On the contrary, when the content of the light diffusing agent is added in excess of 5 parts by weight, the light diffusing agent component is excessively added so that the amount of light passing through the infrared emitting lens 10 is reduced, so that the luminance characteristic of the infrared light is unstable. Losing phenomenon has occurred.
