The reflector 60 is configured with a transparent hole 62 having a rectangular or circular shape so that the UV-B light emitted from the UV-B LED 50 can pass through the lower surface. The UV-B has very weak penetrating power, so if there is a medium or cover other than quartz in the middle, it cannot be transmitted. Therefore, when the bottom of the bio-LED 10 inducing vitamin D synthesis in the body is completely exposed to transmit UV-B Safety against electric shock is improved by the reflector 60 because a person's hand can come into contact with the terminal part of the UV-B LED 50 and a person can get an electric shock due to negligence in use or installation. The penetration hole 62 is configured at a position corresponding to the UV-B LED 50 and is configured the same as the number of UV-B LEDs 50, and the center of each penetration hole 62 is It is configured to substantially coincide with the center of the UV-B LED 50.

Since the wide angle of UV-B emitted from the UV-B LED 50 is 120°, the inclination angle of the inclined surface 63 is 115 to 125°, preferably 120°. When the inclination angle of the inclined surface 63 is 115° or less, part of the UV-B light emitted from the UV-B LED 50 is reflected by collision with the inclined surface 63, and the wide angle of UV-B is reduced to irradiate UV-B. The area is reduced, and when the angle of inclination of the inclined surface 63 is 125 ° or more, the wide angle of UV-B is not reduced, but the portion of the reflector 60 where the thickness is reduced increases, so that the reflector with the inclined surface 63 ( 60) is lowered. The size of the penetration hole 62 and the angle of inclination of the inclined surface 63 are configured to maximize the intensity of the reflector 60 while maximally accepting the UV-B light emitted from the UV-B LED 50. .

A flange fastened to the upper housing and bent and protruding around the lower circumference, a through-hole at a position corresponding to the UV-B LED, extending from the through-hole and protruding upward from the inner bottom surface of the reflector so as to be accessible to the UV-B LED, and extending to the UV-B LED. -B A reflector composed of an inclined surface configured to gradually expand along the direction in which the LED is projected and a strip surface connected to the flange and the upper boundary of the inclined surface extended to the transmission hole and the inclined surface extended to the adjacent transmission hole are configured, ;
Place the UV-B LED inside the upper housing or reflector;
When the upper housing is inserted and coupled to the ceiling, tex, and LED lighting, the flange prevents the upper housing from being inserted further into the ceiling, tex, and LED lighting.
According to claim 1,
The inclination angle of the inclined surface is composed of 115 ~ 125 °, vitamin D body synthesis induction bio-LED, etc., characterized in that.
