Analyze the application of white LED in indoor lighting with ergonomics

As a light source with great development potential, the advantages of LED's long life, solid structure, lower power consumption and flexible dimensions have attracted more and more attention. In recent years, LEDs, especially monochromatic LEDs are widely used in large screens, signal lights and landscape lighting. With the continuous development of LED technology, the luminous efficiency, color rendering, color temperature, power of a single LED and the luminous flux of LED modules of white LEDs have continuously made new breakthroughs. People are full of expectations for the application of LEDs in lighting.

In normal indoor work or activities, people not only require the satisfaction of visual functions, but also a certain degree of visual comfort. This is people’s psychological need for the lighting environment, which requires that the light environment in the field of view should not have direct glare or indirect glare, the color temperature should be appropriate, and the lighting arrangement should be comfortable. In terms of the glare requirements of the field of view, white LEDs are both an advantage and a challenge. Due to the small light-emitting point and beam angle of the LED, the direction of light emission is easy to control, but on the other hand, usually the LED light intensity is relatively concentrated, and if the maximum light intensity distribution is not handled properly, it is easy to cause glare to the observer.

As far as the visual function is concerned, the current LED luminous flux and luminous efficiency are still difficult to meet the needs of large-area general lighting. Therefore, a reasonable lighting design is the key to applying LEDs to indoor lighting. For example, you can use LEDs for local accent lighting, or use LEDs to facilitate control of this feature for auxiliary lighting and dimming design. The design should combine the visual function, psychological and physical needs at the same time, maximize the strengths and avoid weaknesses, and create a healthy and comfortable light environment.
