Embodiment 1

[0040] figure 1 It is a schematic layout diagram of the heat dissipation structure of the light source in Embodiment 1 of the present invention. Such as figure 1 As shown, the light source heat dissipation structure 10 can dissipate heat energy generated when the light source 2 (such as a light emitting diode) emits light. Wherein, the bottom of the light source 2 generally has an electrical contact 22 of at least one of the positive end 222 and the negative end 224 , and a heat dissipation contact 24 . The electrical contact 22 can obtain the power supply PW required to drive the light source 2 to emit light from a transformer, commercial power, primary battery or secondary battery. In another embodiment, the negative end 224 of the light source 2 may replace the heat dissipation contact 24 , so that the light source only has the positive end 222 and the negative end 224 .
