The UGR19 light diffuser is mainly used for diffusing plates on some lamps. The comfort of the human eye to the light is a reference value, so the UGR of the light diffusing plate used by the lamp has a reference value for comfort. Will require UGR less than 19.As one of the Thermoforming Plastic Sheet Suppliers, let us first explain what UGR means. 

UGR is a psychological parameter used to measure the subjective response of light emitted by lighting devices in an indoor visual environment to the human eye. UGR19 is the psychological output of the lighting device in the indoor visual environment that causes uncomfortable subjective response to the human eye. The psychological output is less than 19, which is based on a standard of a summary device. The UGR19 light diffusing plate requires the glare value of the light diffusing plate ( UGR) <19.

It is better to use the UDR<19 light diffusing plate now, so that the comfort of the human eye is better, and the light produced by the lamp is more comfortable.
