COB lens

2025.03.06

COB lens, or COB lens, is a lens specifically designed for COB (Chip on Board) light sources.

Definition

COB lens is a lens specially designed for COB light source integrated with high power density LED chip, which is used for optical processing such as refraction and reflection of the light emitted by COB light source to achieve specific lighting effects.

Principle

Through the optical design of the lens, the light emitted by the COB light source is focused, diffused or the shape of the spot is adjusted to meet different lighting needs.

01 High light transmittance

High-quality COB lenses have a transmittance of up to 90% and can make full use of the light emitted by the COB light source.

02 Precise optical design

Through precise optical design, specific lighting effects can be achieved, such as concentrating light, astigmatism, anti-glare, etc.

03 High temperature resistance

It can cope with the high temperature working environment to ensure the stability and life of the light source.

04 The wide range of applications

It is suitable for many fields such as road lighting, indoor lighting, commercial lighting and landscape lighting and other fields.

Application areas and effects

01 Road lighting

It can efficiently focus the light onto the road, significantly improve the illumination and uniformity of the road surface, and provide a safe and reliable visual environment for pedestrians and vehicles.

02 Interior lighting

Bring soft and uniform light to the interior space, creating a comfortable and pleasant atmosphere. At the same time, it can also achieve anti-glare function and effectively reduce the stimulation of light to the human eye.

03 Commercial lighting

Provide high brightness, high color rendering light, make the color of the product more vivid and real, highlight the display effect, attract the attention of consumers.

04 Landscape lighting

Cleverly combined with a variety of lamps and lanterns to create stunning light and shadow effects, adding gorgeous colors and artistic atmosphere to the landscape.

Development trend

01 Higher light transmittance

With the continuous progress of material science and optical design, the transmittance of COB lenses is expected to be further improved in the future.

02 More accurate optical design

Through advanced computer simulation and optimization algorithms, more accurate optical design can be achieved to meet more complex lighting needs.

03 Better high temperature resistance

New materials and processes are used to improve the high temperature resistance of COB lenses, ensuring their stability and life in extreme environments.

04 Intelligent lighting control

Combined with intelligent components such as sensors and controllers, more intelligent lighting control is realized, bringing more convenience and comfort to people's life and work.

Sum up

As a high performance optical component, COB lens has a broad application prospect and development potential in the field of lighting. With the continuous progress and innovation of technology, I believe it will play a greater role in more fields.
