Embodiment 1

[0027] The present invention firstly provides an LED light source combination structure with efficient heat dissipation function, such as figure 1 and figure 2 As shown, it includes a housing 1 , a lamp bead board 2 , a plurality of LED lamp beads, a heat pipe radiator 3 , a fan 4 , a power supply 5 , an LED driving circuit 7 and a condenser cover 6 .

[0028] Wherein, the shell 1 is made of metal sheet metal, such as aluminum plate or iron plate, and the surface of the shell 1 is provided with a paint film by baking plating to prevent rust. In this embodiment, the shape configuration of the housing 1 is a rectangular box, and the rectangular box is a closed shell structure.

[0029] First, the above-mentioned lamp bead board 2 is made of heat-conducting material, such as copper, and the lamp bead board 2 is fixedly installed in the housing 1; specifically, in this embodiment, one side of the housing 1 (such as figure 2 There is a mounting hole on the left side as shown), ...

Embodiment 2

[0039] The present invention also provides a projection lamp, which includes the above LED light source combination structure with efficient heat dissipation function. Of course, usually the projection lamp also includes a light box, a mechanism for winding film installed on the light box, and various types of optical lenses.

Abstract

The invention discloses an LED light source combination structure with an efficient heat dissipation function and a projection lamp. The LED light source combination structure comprises a shell, a lamp bead plate, a plurality of LED lamp beads, a heat pipe radiator, a fan, a power source, an LED drive circuit and a light gathering cover. The lamp bead plate is made of a heat conduction material and is fixedly arranged on the shell; the plurality of LED lamp beads are arranged on the front surface of the lamp bead plate; the heat pipe radiator is fixedly installed on the back face of the lamp bead plate, the fan is fixedly installed on the shell, and airflow blown by the fan directly faces the heat pipe radiator. The power source and the LED drive circuit are both installed on the shell, the power source is electrically connected with the LED drive circuit and the fan, and the LED lamp beads are electrically connected with the LED drive circuit. The light gathering cover is fixedly installed on the shell, the lamp bead plate is located in the light gathering cover, and the inner wall of the light gathering cover is a mirror surface. The projection lamp comprises the LED light sourcecombination structure. The structure is simple in structure and reasonable in design, and can effectively improve the brightness and quality of the light beam irradiated on the film.

Description

technical field [0001] The present invention relates, in particular, to an LED light source combination structure and projection lamp with efficient heat dissipation function. Background technique [0002] Projector lamp, also known as projector, is a device that can project images or videos onto the screen. When it is used for general lighting, it can be widely used in outdoor lighting projects in homes, offices, schools and entertainment venues. At the same time It can also be used to create various lighting effects and project the required patterns. [0003] Slide projection lamp is a kind of projection lamp. When it works, it shines light on the film to project the picture pattern on the film, and continuously projects the pattern on the film in the form of slides. [0004] However, in the current slide projection lamp, the light source emits a large amount of heat after long-term use. After the heat accumulates, it will shorten the life of the LED lamp bead on the one ...
