Analysis of glare function in COB downlight

There are two reasons for glare:

First, physiological reasons;

First, the reason for the lamps;

Physiological reasons are:

1. Due to the high-intensity stimulation, the pupil is reduced;

2. Light scattering occurs in the intraocular tissues such as the cornea or the lens to form a light curtain in the eye;

3, because the retina is stimulated by high brightness, the adaptation state is destroyed.

The main factors that cause glare in lamps are:

1, the brightness of the light source (the higher the brightness, the more significant the glare);

2, the position of the light source (the closer to the line of sight, the more significant the glare);

3. The size and quantity of the light source (the larger the apparent area, the more the number of light sources, the more significant the glare);

4, the surrounding environment (the darker the ambient brightness, the eye's adaptation to low brightness, glare is also significant).

There are two ways to control glare:

1. Directly limit the brightness of the light source or use a light-transmitting material to reduce glare;

2. Control the glare with the protection angle of the lamp.
