SPOT LIGHT SOURCE AND BULB-TYPE LIGHT SOURCE |
摘要 |
In a spot light source 1 including a case 11, a heat radiator 12 and a light-emitter 18, the heat radiator 12 is formed to have a bowl shape including a bottom portion 12a and a side wall portion 12b extending from the peripheral edge of the bottom portion 12a, and the side wall portion 12b is made of light-transmissive ceramic. Light emitted by an LED element 18b of the light-emitter 18 is guided to the side wall portion 12b by a lens 18d so as to generate a leak light traveling sideways from the spot light source 1, which produces highly decorative effect. |
