Embodiment Construction

[0021] The LED projection lamp provided by the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0022] like figure 1 and figure 2 As shown, an LED projection lamp 100 provided by the present invention includes a casing 10 , an LED lamp board 20 disposed on the casing 10 , an upper cover 30 covering the LED lamp board 20 , and a lamp cover disposed on the upper cover 30 40. The rear cover 50 connected to the housing 10, the lamp post 60 and the lamp socket 70 connected to the rear cover 50.

[0023] see also image 3 and Figure 4 , the housing 10 is made of a polyamide composite polymer thermal conductive material added with graphite, which greatly reduces the weight of the main body of the LED projection lamp 100 . The housing 10 includes a base body 11 and a boss 12 disposed at the center of the base body 11 , the base body 11 is circular, and the boss 12 is a hollow cylindrical shape for fixing t...

Abstract

A projection lamp utilizing light emitting diodes (LEDs) includes a housing, a lamp board positioned on the housing, an upper covering the lamp board, and a lens positioned above the upper cover. The lamp board includes a plurality of LEDs. A majority portion of the housing and the upper cover is composed of thermally conductive materials. The housing includes a plurality of latch holes, the upper cover includes a plurality of latching chambers corresponding to the latch holes, and the lens includes a plurality of latching members extending through the latching chambers to engage the housing latch holes.

Description

technical field [0001] The present invention relates to a projection lamp, in particular to an LED projection lamp. Background technique [0002] LED (Light-emitting Diode, light emitting diode) lighting source has the advantages of long life, energy saving, green environmental protection, rich color and miniaturization, and is called the next generation of light source and has attracted much attention. With the continuous development of energy-saving technology, LED lights will be the direction of the future development of the lighting industry. However, LEDs convert a large part of the input electrical energy into heat energy, and because the LED chip area is small and the heat generation density is high, the key to the development of LED lighting is to solve the problem of heat dissipation first. The junction temperature is an important technical indicator to measure the heat dissipation performance of LED lamps. The increase of the junction temperature due to poor heat ...
