Embodiment Construction
[0030] see figure 1 As shown, the lamp of the present invention has a light cover 10, the light cover 10 is a light-transmitting material, such as: plastic or glass formed, and combined with the cover body 20 to form an internal space 12, the light cover 10 will be arranged in front of the LED module 30 to evenly project the light emitted by the LED module 30 . The heat dissipation unit 40 can conduct heat conduction (heat dissipation) to the heat energy generated by the LED module 30, and is arranged at the rear end of the LED module 30. In this embodiment, the heat dissipation unit 40 includes a combination of a heat pipe 42, a heat sink 44, and a base 46. , but not limited to this combination, aluminum extrusion can also be used to form heat sinks. The LED modules 30 can be arranged in a variety of ways. The LEDs 30a can be directly planted on the base 46 of the cooling unit 40 as shown in the figure of this embodiment, or the LEDs 30a can be installed on a substrate first...
