How to reduce glare from LED lights

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. retail store lighting LED lights denledgiaphuc

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.

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.
