What is the anti-glare effect of COB lens?
With the continuous development and progress of science and technology, COB lens will be used in more and more industries and fields because of its unique advantages. The continuous enrichment of material production also prompts people to pursue a more advanced, flexible and personalized life experience to better meet people's production and living needs.

The following editor will introduce to you what is the anti-glare effect of COB lens? content, welcome to read!

Anti-glare can be considered from the following four angles:

1. Lamp material

Just like a ceiling light, the light source of the downlight is "weakened and dispersed" by some translucent materials.

"Frosted lens" is the most commonly used anti-glare design for downlights. The effect is very direct but there are also disadvantages, there will be no beam angle, no arc. The lighting effects of frosted lenses and "clear glass lenses" are a bit like soft and hard edges.

2. Lamp structure

Some anti-glare designs add "honeycomb mesh" to the "reflector cup" or "lens", which is equivalent to dividing the non-reflective material into several small areas, and the residual light hits the side of the black honeycomb mesh to reduce residual light Random reflections, while converting light into indirect light with a custom honeycomb grid will bring better anti-glare effect.

Deep tube anti-glare

This is the anti-glare method related to the shading angle. Only when the shading angle is above 45° can it meet the current home environment standard. The method to judge whether the shading angle reaches 45° is to see whether the depth from the plane of the mouth to the light source is similar to the length of the thumb.

Optical lens anti-glare

The anti-glare method mentioned above makes users doubt whether it can reduce the length of the lamp while ensuring the anti-glare effect. This can be achieved using optical lenses. The convex lens can stretch the distance between the light source and the window, expand the shading angle, and ensure the anti-glare effect while ensuring the compactness of the lamp body.

Polarized anti-glare

This is more complicated. The lamp itself separates and combines the light source and the light outlet. The light source uses a high-performance optical lens and a honeycomb grid of the light outlet to physically reflect the light. At the same time, the light outlet can be rotated 360° laterally and the light source can be rotated flexibly, which can skillfully change the window angle and shading angle.


3. Color of reflector

"Black reflector" can reduce light leakage and achieve anti-glare. The "matte" one has better anti-glare effect than the glossy one.

4. The number of lamps
What is the anti-glare effect of COB lens?
The number of lamps should be planned according to the size of the space, lighting, wall and floor design, personal needs and many other factors. There are too many lamps, and the illumination of the space exceeds the standard value, which is easy to glare.

Illuminance: Illuminance generally refers to the intensity of light. Light intensity is a physical term that refers to the luminous flux of visible light received per unit area. referred to as illuminance.

5. The location of the lamps

The higher the position of the luminaire, the less likely it is to generate glare.

6. Material

The most common ones are "plastic shell" and "aluminum alloy shell".

The best color rendering index is about 90, and the external driver is selected. The external driver is flexible and its performance is better than that of the general built-in driver. It is also easier to maintain and replace in the event of a failure.

7. Color temperature

General lamps have 3 grades of color tone, warm white 3500K, neutral white 4000K, and cool white 5000K. Recommend 4000K neutral white, warm and bright, whether it is kitchen, bathroom, bedroom, living room and other spaces, it is more suitable.

If you have a secondary ceiling at home and you need to add light strips in the later stage, you should try to ensure that the "color temperature" of the light strip and the spotlight is the same to avoid the effect of "colorful white".

Different brands have different naming principles for different color temperatures, resulting in different names. Therefore, it is best to choose according to the color temperature, do not look at the name alone.

8. Power

The higher the power, the higher the luminous flux. We have to choose different power spotlights and downlights according to the different needs of different regions. Choose 3W for decoration, medium wattage in well-lit areas, and large wattage in dimly lit areas. Of course, it also depends on the number of lamps.
