What To Look for in LED Light Strips
Just as the market for LED light strips has expanded, it’s also become more complicated to find exactly what you’re looking for. If you want to make sure you’re getting exactly what you hope for, be sure to follow these tips.

Don’t worry too much about brand name, instead focus on features and reviews. Most of the LED light strip market is dominated by small brands you’ve probably never heard of before. This can be confusing and a bit intimidating, but try not to worry too much. Instead, focus on the features the light strip offers. Does it have the Bluetooth connectivity you’re looking for? Is it single-color, RGB, or RGBW? Remember, while RGB strips can produce white, only RGBW strips can produce a clean white like true lightbulb. Once you’ve decided that it meets your needs, look carefully over the pictures, and then see what other users have to say in the review section. Those three things will offer you the best insight into whether the company is rebranding a cheap strip or is actually in the business for the long run.

The second thing to look for is the type of lighting the strip actually provides. Don’t rely on the picture alone, especially if you’re purchasing an RGB strip. If you’re searching for white lighting, be sure it has the color temperature you’re looking for. If you’re shopping for RGB, you’ll want to find out how its RGB lighting works. Can you set it in sections or is it whole strip only? Is the lighting static or does it flow? Are their presets and, if there are, can you customize them or create your own? With so many options, don’t be afraid to move on to another listing if these answers aren’t clear.

Third, pay close attention to how you control the lighting. Many low-costs strips use a remote while more expensive often features smartphone apps. While the remotes can work just fine, you’re often more limited in color, brightness, and customization than app-enabled lighting strips. If you do choose an app-integrated strip, be sure it connects the way you intend. Bluetooth light strips offer more fast and easy setup, but smart home integration, such as Amazon Alexa or Google Home, require Wi-Fi.

Finally, keep in mind how long of a strip you actually need. It’s possible to cut many LED strips to size, so you don’t have to be exact, but if you’re going for RGB, shortening the length could impact what lighting is able to be displayed and how well your strip matches the app. Don’t cut the tail off your rainbow.


8 Common Problems with LED Lighting How to Fix

2021-04-13 20:08:57 | LED Lighting

Khi sử dụng đèn LED, nhiều sự cố thường gặp có thể xảy ra như nhấp nháy, ù, bóng không đủ sáng, chói, ... Nếu không xử lý kịp thời những vấn đề này có thể gây hỏng mạch điện hoặc bóng đèn của bạn, hoặc Bài viết này sẽ giải quyết và khắc phục các sự cố mà chúng ta thường gặp phải, để cải thiện chất lượng ánh sáng LED.

Các sự cố thường gặp hàng đầu với đèn LED

1. Tại sao đèn LED của tôi nhấp nháy?

One of the most common problems when using LED is the light flickering. The lights are basically strobing. If you are using poor quality LED bulbs or flood lights, then you will observe the brightness goes up and down rapidly. If the flicker frequency is below 80 to 100 Hz, then it can be observed by naked eyes. It can be a serious issue as flickering lights might cause fatigue, headache, vomiting or even trigger epilepsy. It is difficult for our eyes to adapt such the flashing lights; thus, we need to know why and fix the flickering problem on LED lights.

Reason 1: Loose wire connection

If the wire connection is loose between the bulb and circuit, you may encounter flashing lights. It is because the current would be periodically obstructed due to the electromagnetic interference. The way to fix it is to inspect all connection points in the circuit to see if there are some wires are about to break or disconnect.

Reason 2: Low quality LED

If you buy the abnormally cheap LED lights, you will get flickering quickly. Due to the poor soldering technique of gold wire with LED chips, the intrinsic components will be loosened easily. In addition, the shoddy LED bulbs will have poor PCB design that does not receive the current properly, so we will see rapid fluctuation of brightness.

One of the effective ways to solve this issue is to buy quality LED lights from reputative brands, and we can take a look at the brand of LED chips they use. For instance, CREE XTE or Osram Square would be the better options. They apply the eutectic soldering technology to eliminate the flickering on LED lights.

Reason 3: Loose bulbs

The LED will have flickering problem if you do not tighten them firmly in the fixture. The poor contact between the bulbs and base will affect the transmission of current. Before inspecting the LED lights, we should shut off the bulbs as well as power supply to prevent electrical shock. If your room is completely dark after turning off the lights, we can put a portable work lights under the fixture to provide ample brightness.

Reason 4: Improper dimmer setup

Knowing your dimmer type is critical to diagnose the problematic strobing LED lights.

The pulse means the current and voltage sent to the bulbs while the width is the duration. PWM dimmers alternate the pulse duration to decrease the overall brightness. In other words, it rapidly shutting on & off the lights to dim the LED lights. The poor-quality dimmer switch generates electrical signal with improper pulse width (<100Hz), and thus lead to observable flickering of LED. The strobing effect is especially significant if you further dim the lights because the duration between each pulse is longer.

It might be inevitable as it is the working principle of this type of dimmer. Digital dimming can solve this problem because it uses different working mechanism.

Constant Current Reduction (CCR) dimmer

As its named suggested, it alters the current of the circuit to produce different brightness. It is generally worked for 0 to 10V DC power supply. The power supply will send the corresponding dimming signal to the lights. In this case, continuous current is supplied and no discrete pulse is formed in the circuit.

Reason 5: Power supply broken

If you are having high power (>100W) LED flood lights for backyard or sports ground, the bad driver (power supply) will cause flickering problem. Before purchasing the LEDs, we can have a look at the driver unit, Mean Well is one of the best and reliable power supplies for LED lights. Its failure rate is approx. 0.3% in the first 2 years.

Reason 6: High wattage electrical appliance

For those who have many high-power appliances at home such as air conditioner, heater, vacuum or etc, the bulbs might flicker if you draw a lot of voltage in the same circuit. To fix this problem, we can turn off some of the devices to see if the flickering light problem is improved.

No flicker LED sports lighting

Flickering problem is also very common in LED commercial & sports lighting. Their lighting standard is even higher than residential application. Apart from no visible flicker in human eyes, the LED lights must not strobe under the high-speed camera. Imagine we are taking >960 fps video and the flickering would greatly affect the picture quality.

LedsMaster’s LED sports lighting are using constant current reduction dimming. They support up to 6000 Hz high speed photography. They are applied to football stadium or other sports venues holding international competitions.

2. LED lights with buzzing noise

Buzzing is another common problem of LED lighting. If your recessed lights or other LED bulbs product such the annoying hum, it might indicate that you overload the circuit. For instance, if the dimmer is just support 300W LED lights but you connect over 200W luminaires, then buzzing would occur.

Where does the sound come from? It is mainly due to vibration of the electronic components inside the lamp. They vibrate in a specific frequency such as 100 to 120Hz.

The buzzing of LED lights indicates abnormality. Once we hear it, we should inspect the lamp, as well as the circuit to ensure safety. Besides, we can also disconnect some of the luminaries to see if we can improve this problem.

3. Why are LED light bulbs are not bright?

After the painful lighting installation, it is common for the people to ask why the LED lights are dim. This problem happens for both indoor & outdoor LED bulbs. Let’s explore the following reasons.

a. Improper power supply for LED lights

If the LED is not working in the rated voltage & current, then the LED lights cannot reach the maximum brightness. When buying the LED lights from manufacturer and you wish to use your own driver, you need to clearly know what is the power, voltage and current input of the LEDs. If the power rating of the driver does not match that of LED, the flood light bulbs will not be bright, or even burnt out. Therefore, it is highly recommended to adopt the original setting of the whole LED lights.

b. Loose wire connection

Similar to the LED bulb flickering, if the wires are not firmly connected, then some of the LED chips inside the lights will not on, and thus reduces the overall lumen output.

c. Aging of LED lights reduce overall brightness

The LED lights are not bright if they have used for a long period of time. The reason is that the electronics inside the lamp starts to deteriorate, and thus they no longer product the 100% lumens. If a LED light is rated as 80,000 hours at L70, the lumen output will fall to 70% of the original value after 80k hours.

It is the normal wearing of LED lights. Nowadays, majority of LED have the life span of 50,000 to 100,000 hours, which is equivalent to 20 to 30 years depending on how long you switch on the bulbs.

d. High ambient temperature lead to dim LED lights

Householder might also complain their LED lamps are not bright if the ambient temperature is high. According to the scientific research, LED produces the maximum brightness at around 25°C junction temperature.

If the working environment is very hot such as 40°C to 60°C, the lumen output of white light drops to approx. 65% to 80% of its maximum value.

On the contrary, cold environment is beneficial to LED because it can be even brighter than its original value.

For industrial application such as foundry and nuclear power station, the ambient temperature can be over 80°C. Thus, special reinforcement on LED luminaires is required.

4. Dimmer does not work with my LED

Some may complaint the LED lights cannot be dimed after connecting to dimmer switch. Firstly, we need to check if the bulb is dimmable. Before you buy the LEDs, you can clearly see the bulb is stated as “dimmable” if they are. If you connect a dimmer switch to non-dimmable LED bulbs, it will usually remain 100% on, no matter how to adjust the brightness on the switch. It is because the PCB of the that LED is not designed for dimming circuit. In addition, it is quite risky to do so because it might damage the LED due to the improper current and voltage during dimming.

5. How to reduce glare from LED lights?

Glare means the strong blinding lights coming out from the light source. It can blur our vision and affect our living quality. For instance, it would be very difficult to read the words on the magazine due to the reflection. Also, white reflective glare of the lights will create white spot on the TV screen.

How to calculate the power of LED bulb required for my home

Reducing the brightness is one of the ordinary ways to fix glare. For home lighting, we can avoid unnecessarily bright lighting by calculating the number of LED bulbs you need. If you have a 20 sq. meter living room, then the lumen required is approx. 20 sq. meter x 150 lux = 3000 lumens. Since most of the LED lights have the luminous efficacy of 130 lm/W, the power of LED bulb required is 3000/130 = 23W. We can add around 20 to 30% to this value (23W) to compensate the reflection of wall and other kinds of energy loss.

If you have a garage, then it is suggested to use the lux level of 500. Since we need to do the repair task in the workshop, we will need brighter lights.

Another way to reduce the glare is to add the barn door near the LED bulbs, to make the light beam more directional. We can create a 3-wall cover for the lamps, so we will not directly see the light source on the side of the lamp. It is especially useful for outdoor flood lights.

6. Blue light pollution

Blue light is another widespread problem of LED light. Although blue light can improve our reaction time and mood, it does impact our health at night. The LED blue lights can suppress the melatonin production inside the body, and thus affect our sleep cycle and quality. The blue light might also damage retina for prolonged exposure. The leakage of blue light will also pollute the sky and cause skyglow at night.

To reduce the amount of blue lights, we can select the LED bulbs with lower color temperature such as from 3500K to 5000K. The LED would produce more blue light for the color temperature over 6000K. Depending on your need and preference, you can select the warm white LED (around 3000 to 3500K) to create relaxing atmosphere.

7. How to improve uniformity of LED lights?

Another common problem is the low uniformity of LED lights. What is uniformity? It basically shows how even the light distribution in an area. As we can see from the above comparison, the left tennis court has low lighting uniformity. There are four observable light spots on the ground. In such the low uniformity, our eyes will not be able to see the whole ground. The uneven dim & bright lights will also fatigue our eyes because our eyes need to adapt to this change continuously.

Một trong những cách phổ biến để khắc phục vấn đề độ đồng đều thấp này là sử dụng đèn LED với góc chùm tia lớn. Đó là vì đèn có thể lan ra bên ngoài đèn. Để cải thiện hơn nữa độ đồng đều, chúng ta thậm chí có thể sử dụng phản xạ thứ cấp để làm sáng khu vực Ví dụ: chúng ta có thể hướng đèn pha lên trên trần nhà và do đó sử dụng đèn phản chiếu để chiếu sáng các khu vực trong nhà, chẳng hạn như nhà hoặc sân thể thao. Vì vậy, bạn sẽ có được độ chiếu sáng đồng đều cao vì trần nhà hoạt động như một bộ khuếch tán. Tuy nhiên , hạn chế là chúng ta sẽ cần nhiều đèn LED hơn vì một số lumen được hấp thụ bởi trần nhà và các chùm ánh sáng bị phân tán theo các hướng khác nhau.

8. Đèn LED đắt tiền

Khi chúng ta so sánh giá của đèn LED với các nguồn sáng khác như metal halide, halogen của CFL, chúng ta sẽ thấy rằng LED thường đắt hơn các loại khác, đó là do vật liệu sử dụng và cơ chế hoạt động của chúng khác nhau. chi phí mua đèn LED cao hơn nhiều, bạn sẽ nhận ra đây không phải là vấn đề vì nó bền lâu hơn và tiết kiệm năng lượng!

Một bóng đèn LED thông thường có tuổi thọ từ 50.000 đến 80.000 giờ, chúng ta có thể so sánh giá trị này với bóng đèn sợi đốt từ 1.000 đến 2.000 giờ. Thêm vào đó, công suất tiêu thụ của đèn LED bằng khoảng 1/10 của đèn sợi đốt để tạo ra cùng độ sáng.
