Embodiment Construction

[0020] see figure 2 , which is an exploded schematic diagram of the structure of the LED projection lamp of the present invention. The LED projection lamp of the present invention includes a casing 1 , an LED light-emitting chip 2 , a heat dissipation unit 3 and a control unit 4 . The LED light-emitting chip 2 is installed in the casing 1 , and the cooling unit 3 covers the outer surface of the casing 1 ; the control unit 4 controls the rotation of the cooling unit 3 .

[0021] Specifically, the housing 1 is hollow and cylindrical, and in this embodiment, it is a cylindrical structure.

[0022] The heat dissipation unit 3 includes a plurality of sub-heat dissipation units. Please also see image 3 , which is a schematic structural diagram of a single sub-radiation unit. Each sub-radiation unit includes a vane 31 , a transmission rod 32 and a pinion 33 . The top of the transmission rod 32 is fixed on the blade 31 , in this embodiment, the top of the transmission rod 32 is...

Abstract

The invention relates to an LED (light-emitting diode) projection lamp, which comprises a shell, an LED luminous chip, a radiation unit and a control unit, wherein the LED luminous chip is arranged in the shell; the radiation unit comprises blades; the surface of the shell is covered by the blades; the control unit is used for controlling the rotation of the blades of the radiation unit. According to the LED projection lamp, the control unit is used for controlling the rotation of the radiation blades, so that dust can be effectively prevented from entering the shell by closing the radiation blades when the projection lamp is turned off, and the surfaces of the radiation blades can be effectively and conveniently cleaned.

Description

technical field [0001] The invention relates to an LED projection lamp, in particular to an LED projection lamp with a heat dissipation structure. Background technique [0002] Due to the strong light, the LED projection lamp has a high concentration of light energy and a long projection distance. It has the characteristics of very long life, good environmental protection, good impact resistance, good shock resistance, not easy to break, easy to transport, and energy saving. In addition, LED spotlights also have other advantages, such as high light quality, basically no radiation, and low prices. They are typical green lighting sources; they are reliable and durable, and the maintenance cost is extremely low. It is precisely because LED spotlights have the characteristics that other solid light sources cannot match, and are widely used in various fields. [0003] Existing projection lamps include a casing and cooling fins, wherein the cooling fins are located in the casing....
