PURPOSE: An illuminator with a multi separated incidence angle is provided to concentrate a light source by refracting the light source from an LED lamp. CONSTITUTION: A lamp case(110) includes an open lower part. A plurality of LED lamps(120) is installed on both sides of the lamp case to emit light to the outside. A reflector(130) reflects the light from the LED lamp with other refractive index. The light emitting shade(140) is formed on the lower part of the lamp case. The light emitting shade concentrates the refracted light from the reflector on an incident boundary face. |
