The problem is that the wavelength of the light

2017-08-16 13:54:27 | 日記

<p>The problem is that the wavelength of the light is dependent on the gas and energy jump so the light has a very peculiar quality as you may have noticed when looking at fluorescents. To understand why, let's look at the other commercially available sources of light. Great if we want to heat a space. LED's are simpler.What about color of the light. Incandescents use the resistance to electrons (not a good start to efficieny) of a given material to electrons to heat the material and then generate light. They excite a contained gas which absorbs electrons and spits out photons. 1000 lumens is twice as bright or intense a light as 500 lumens if generated at the same "color" (generally measured in Kelvin for temperature of light).First, what's our measure of brightness? The best yardstick (excuse the word) is the humble lumen. Any time you see "Super" in some description of a product, immediately you tend to recoil. The ad wizards of the 70's killed the word for most commerical application but with LED lights, it's not just some hokey branding title. First, let's tackle the lumens part of our equation. Generally speaking, the higher Kelvin of light, the whiter or brighter we perceive the color. Light is almost a bi-product of this method. Based on this, we can reduce our wattage significantly and still generate the same brightness of light if not brighter. Super bright actually means something when describing LED light. Super bright has a very real meaning with LED lighting and it's a primary reason why many people seek out this solution until, of course, they realize how much they can save by switching to LED's. 90% in fact. This is more a perceptual effect as our eyes (actually the brain) process different wavelengths of light. The efficiency of this method is significantly better than the other two methods as a measure of how many photons are generated for a certain amount of incoming electricity. Certain venues such as hospitals, office, industrial, and outdoor lights probably don't want to foster a warm, snuggly, "let's take a nap" kind of vibe so bright or superbright light is the right way to go. Why are LED's so good at producing Lumen's? Well, you could say it's the most efficient means of turning electrons (measure of electricity) into photons. The light generated is based on a "black body cavity" means and the wavelenths are generally very broad (many different colors of lights). We associate this light quality with being away, alert, and clean. Super bright, when describing light, is generally thought of as having a large lumen count with a high Kelvin color and our LED lights can selected and <a href="http://www.outedsionbulb.com">edison lamp</a> color-tuned accordingly. Super this, super that. Around 3500 would be daylight and lower than 3000, would be "warm" light which has a yellow or red hue in terms of how we perceive it. For functions where the <a href="http://www.linsheng.com">Emergency Light</a> quantity of light is important, let's take a look at what "Super bright" really means. This allows an LED to produce large amounts of lumens which translates into very intense or bright light. Lumens is what we really want to measure when looking at brightness with a secondary role for the "color" of light. Lumen is a measure of the quantity of photons (the smallest individual packet of light) that are delivered. We'll look at both aspects and explain how to get the brightest, or super bright light through LED's. Most of the electric energy is being turned into heat.. A 5000 K light is considered to be bright white.Lumens are very easy to quantify. The diode drives electricity to a material that absorbs it and then generates a resulting photon.We get it. Fluorescents are more efficient but in a very round about way.</p>


I think they're right that the president is wrong

PALM BEACH, Fla. "I think they're right that the president is wrong," Walker told me, "but I also think we've got to make sure that homeland security isn't compromised.When Walker told the story at the Freedom Summit in Des Moines, Iowa, in late January, the audience ate it up — just loved it — and Walker was rewarded with rousing applause. In recent weeks, for example, he has cited his command of the Wisconsin National Guard as evidence of national security experience, and in Palm Beach on Saturday, he pointed to Ronald Reagan's 1981 firing of the air traffic controllers as "the most significant foreign policy decision of my lifetime" — a decision made, in case anyone missed the point, by "a president who was previously a governor. Then he pulls out his Kohl's credit card and there's another 10 percent. In the end, Walker left the uncomfortable impression that he hadn't considered the question very seriously. On the other hand, Walker's way-outside-the-Beltway method of expressing himself might resonate with voters in primary and caucus states more than Washington thinks. But we're here, and we're not going to complain about it.At the same time, Walker could be headed for trouble with the establishment, Washington-based wing of his party. It's about leadership. Under instructions from his wife Tonette, Walker has learned how to pile on the discounts and coupons whenever he goes to the popular Wisconsin-based department store. Certainly some parts of his performance before the Club for Growth led observers to suspect that he has not really dived into a number of big issues — not just foreign policy, but domestic as well — that will serve as tests for presidential candidates in coming months. If he sees a shirt on the rack with a tag that reads, "Was $29. All the other candidates who came to Palm Beach — Bush, Cruz, Rubio, Jindal — quickly and clearly said Ex-Im should be allowed to expire. Whatever the case, Walker insisted that "Foreign policy is something that's not just about having a Ph.Still, all that has led to some feelings of unease among policy experts and Republican insiders that Walker, for all his outward popularity, might be headed for difficulties over the substance of policy. Fast forward to Saturday morning, here in Palm Beach, when Walker told it again at a meeting of wealthy donors sponsored by the Club for Growth in an ornate ballroom at The Breakers, one of the most opulent hotels in America. But Walker still saw value in telling the story. Bush in 2000. On the one hand, they'll have a point — Walker needs to come up with clear, crisply-expressed positions led street light on a variety of national and international issues."Walker's comparison set off a lot of debate over whether the air traffic control firings, as consequential as they were, really supported the point Walker was trying to make.It's not clear whether Walker's problem is temporary or longer lasting. "Totally," Walker said, without a moment's hesitation.Ds. But he caught a slingshot out of Iowa and instead finds himself at the top of many GOP lists at a very early point in the race.What does that mean, exactly? It's not entirely clear. "Not just Republicans, I think the Congress as a whole needs to find a way to fund homeland security going forward," Walker answered.Ds — and is working on foreign policy questions. "So even if they don't necessarily relate to that story, I think they appreciate that someone like me can tell that story and relate to the people who we're going to need in the next election."After a little more along those lines, I said I was still a little unclear on where Walker stood."Probably not as many Kohl's shoppers here," Walker said dryly when I asked him afterward about the contrast. "And the next thing you know, they're paying me to buy that shirt!" Walker exclaims.'"At The Breakers, in front of the contributors whose approval all GOP candidates hope to win, it wasn't quite the same. Should Republicans stand firm on not funding Obama's unilateral action on immigration, or should they go ahead and fund the Department of Homeland Security without regard to what Obama has done? Here is what Walker said:



I think they have to figure out some way to have the bridge to continue to fund homeland security but in a way that doesn't remove their ability to come back sometime in the not too distant future if the court rules or if the administration changes how they do this action in a way that could LED Panel Light be upheld in court.


It wasn't exactly a straightforward answer, and the Club questioner noted that the audience would have liked to hear the word "eliminate."Walker assumed that in the best-case scenario he would be in for a long, slow move to the front of the Republican pack." Walker noted that he was part of the states' lawsuit against Obama's action. The reception to Walker's story was polite, but noticeably more subdued than in Iowa. From Jeb Bush, with his long exposure to both state and national governance, to Marco Rubio and Ted Cruz, senators who speak with some authority on big issues, to others like Bobby Jindal, and potentially John Kasich and Mike Pence, who have experience on both the state and federal stage — other candidates are ahead of Walker in their ability to come up with sharp and well-argued statements on domestic and foreign policy. Now he has to take some time to catch up with himself."We thought all along if we got in, it would be kind of this slow and steady, don't worry about the other guys, just keep focused on moving forward, and as candidates chose not to get in or fell off, we'd be in a position to make a compelling case to them," Walker explained. — Scott Walker likes to tell a story about shopping at Kohl's. He'll appeal to more voters by not getting stuck in the Washington mud. "A lot of these donors were frustrated after the last election because they were feeling … that Americans couldn't relate to our nominee," he told me. But not Walker." Walker eventually said he did not support re-authorizing Ex-Im, but it took a while to get there..On the other hand, maybe Walker just hadn't thought it through very carefully. Part of the difficulty is that he has found himself far ahead of where he thought he would be at this stage in the race, and is thus under a much hotter spotlight than he might have imagined. Here's how he answered the question:



I think again, if you do what I mentioned with the tax code, if you make it fair and simple, if you do trade overall that's open and fair going forward across the world, across the globe, and you simplify the regulatory code, then the most compelling argument people would say is that this Bank is there because other countries have it, somehow we need it out there -- I think that's a faulty argument and premise, but I understand why today, when you've got all these other various regulations and a tax code that doesn't work and other things, but if you simplify the tax code, you simplify the regulatory climate, you pull back the frivolous and out-of-control lawsuits, there's no need to have it, and let the market drive everything, and those that are worthy of the competition, big or small, I think, will do well. Yes, he has a huge record of achievement as a governor.99," Walker explains, he goes to the cash register with a flyer from the newspaper and gets another 10 or 15 percent off. They need to have the power of the purse string to offer a counter to that." In our conversation, he said he has gathered together advisers — some of whom do have Ph.One easy question, at least as far as members of the Club were concerned, involved the Export-Import Bank. And for that reason, Walker looks like the man who can attract almost everyone in the Republican camp — social, economic, and national security conservatives — in addition to those disaffected voters. He explained that he recognized the concerns lawmakers have about giving up their ability "to push back on the president's questionable, if not illegal, actions.99, Now $19. But will that be enough to get him through a long campaign?In contrast, other Republican candidates — some with less impressive records of accomplishment than Walker — have shown a lot of fluency with national and international issues.For example, in our conversation Saturday, I asked Walker what Republicans in Washington should do in the standoff over funding the Department of Homeland Security. Look for GOP insiders to begin whispering, and then saying out loud, that Walker needs to raise his game if he is going to play on the national stage.D or talking to Ph. On one hand, it appeared Walker was adopting the time-honored stance of the governor who stands outside the squabbling of both parties in Washington — a tactic that last worked quite well for George W. "In Iowa, the people went 'Yeah! We feel great when we get that 30 percent in the mail."That's a huge part of Walker's appeal right now: He seems to be the Republican candidate who has the best chance of connecting with the millions of middle-class voters who have drifted away from the GOP in recent elections. That's a huge plus for Walker and, along with his impressive record in Wisconsin, is the reason he has shot to the first tier of the Republican race in recent weeks. And another newspaper flyer that might be worth as much as 30 percent off. No one expects a governor to have dived deeply into international affairs this early in the race, but Walker is definitely a work in progress. "We had no idea that after that Iowa summit there would be that kind of acceleration to the race. Walker will have to reach beyond his record to compete with them on the issues and present himself to voters as a potential president.And then there was foreign policy. In our conversation, I asked whether the campaign had shifted under his feet. The Club wants to see it die; that's a good conservative position.


To insure that these lights work consistently in the water

2017-08-07 15:29:27 | 日記

To insure that these lights work consistently in the water; I propose that we use some new technology being introduced in consumer flashlights. It would be smart to outfit such water toys with bright white LED flashing lights.



Generally you have to wait thirty seconds for the engine's oil pressure to come up anyway and thus the anti-collision warning system will light up right away.com/gear/details/ee_shakelight.uiuc. If they get too dim from too smooth of water, yah, we wish, then the system would revert back to the battery.modernoutpost. As the jet ski hops across the wake and waves the vibrational energy can shake the power system to keep the flashing lights on.html



Here is a quick movie you can watch online to see how this technology works.edu/LectDemo/scripts/demo_descript. Perhaps this is a good way to save lives on the water? Think on this.



Every year there are more and more jet ski accidents bulb edison in the United States.



This does not mean that the anti-collision lights would not be hooked up to a battery, only that you would not be asking for any juice.idc?



Currently there are some nifty micro-flashlights being used which you can buy which use a similar technique and are available thanks to the Everlight Flashlight technology research lab. In fact the number of deaths per year is increasing. The bumps on the water can power up the anti-collision warning lights using electromagnetic induction technology to charge a capacitor instead of the lights working off a battery.modernoutpost. Here is a link to this home use flashlight:



I propose we use the engine rumble to light up the dashboard of the jet ski and anti-collision flashing lights. These smaller flashlights work by shaking them for about thirty seconds and shine for about 6 minutes and they shine quite bright since they use a very bright LED light. As the jet ski moves faster over the waves it will automatically increase the intensity of the light and make it brighter, thus adding more safety.



I then had to obviously announce my presense in the room

2017-08-05 16:05:42 | 日記
Now I know what you're thinking- "everyone poops in private".

I poop. I then had to obviously announce my presense in the room.

But I'll tell you what I do. By private, I mean that there's one toilet, and the door locks. Then she left. She told me she would replace it later and to take my time. Others often try at the locked door- the only degree of separation that exists between me and them. NOT TRUE. Another thing that you might not have known about me is that I am a secret pooper- I poop in private. Well, it's true.but now you all know what to do in case this happens, to you. The average person assumes the bathroom is closed and locked, as stated earlier. Sometimes other people are in that room with them. It is a most frightening situation that often makes me poop myself (HA! I just realized that too). She began to open the locked door with her key.. In the lobby of a few select buildings on the beautiful Green Mountain College campus, private bathrooms exist. I heard her enter the first room, and quickly turned out the light. I was dumbfounded. Other locations on Heat Sink Supplier campus also provide private bathrooms. The part that I was in. The cleaning lady on my floor once entered the bathroom's small outer room- the room containing a sink and mirror which precedes the toilet part of the bathroom. However, there are times when I am not able to reach the lightswitch in time, in which case, I continue pooping, and I attempt to do so as loudly as possible. However, when you are one of the only people who holds a key to a bathroom you clean, or possibly close at times, you know better. However, I wil attest to the fact that I am not the only secret pooper.. The part that locks.

Much to my dismay, I was once involved in what I call a secret pooping disaster (SPD for short). I burst out with the first thing that came to my mind- "Someone is in here", which she followed with, "Oh, sorry.. That's why I'm a "secret pooper". I bet you didn't know that. What was I to do? I couldn't just tell her I turned in out because someone was coming in! I couldn't tell her I enjoy pooping in the dark (I don't, but I wouldn't want to make up such a story).

That's why I poop in private. Others poop in public bathrooms, generally having over two stalls (it's awful, I know).

Perhaps I shouldn't turn out the light. I poop. They get out of there fast, too. That fact has lived with me all my life. why is the light out?". Well, actually sometimes I turn off the light, so the bathroon appears to be closed and locked- which easily deters these "intruders". Sometimes, those other people are also pooping (YUCK!). No one in their right mind wants to be around when someone else is pooping.

. Nothing.. I do absolutely nothing. So I did the only thing I could- I told her the blub kept flickering and was now out

2017-08-04 14:01:20 | 日記
The lights on the street play a vital role especially for motorists during night time. It allows a smooth flow of vehicle traffic and prevents any untoward accidents like car collisions and robberies. Now a Days LED Street Light Manufacturers are in big demand because of huge requirements of led street lights and adapting new technology and all led lights have save maximum energy and gives bright light compared to others because of this reason led street light manufacturers are great demands in these days. Led street light manufacturers do not make use of chemicals during manufacturing because of this reason only LED Street Light Manufacturers popularity keep on growing.

Criteria followed by LED Street Light Manufacturers:

1. Energy Saving: all people moves to energy saving and eco friendly led bulbs so led street light manufacturers prefers most on this at the time of manufacturing because of this reason only led street lights are environmental friendly.
2. Radiation less: All the sectors have shifted to use of led bulbs because led street light manufacturers do not use led and mercury.
3. Durability: LED Street Light Manufacturers should maintain constant durability what they are maintained in the early stage.
4. Breakage: Another criterion for led street light manufacturers are they should manufacture led street light are resistance to heat, shock and many vibration to avoid easily broken.

Customer Attention about LED Street Light Manufacturers:

a) Prefer best LED Street Light Manufacturers because brand name will differ from one company to another.
b) Prefer best lifespan led’s, some led street light manufacturers will provide greater lifespan led’s.
c) Give much attention about waterproof led’s because we have to make use in all weather condition.

g) Prefer light weight led street light bulb.

Advantages of LED Street Lights:

The most important advantage of LED street lighting compared with standard lighting is the small amount of energy it needs to function properly. Mercury bulbs need 35 (lm) to work while LEDs need 100 (lm). They are also friendly to the environment since they do produce any emissions because of their compact state. They can also last for thousands of hours.

With so many uses and benefits, it is no longer a secret as to why LED Street Lighting has become a hit amongst the population. Even solar Street lights are also economical and Eco friendly.
