Problems solved by technology

[0006] In order to solve the above-mentioned problems, the present invention provides a projection system, in which the air guide method and fan configuration can help the light source and the optical module to dissipate heat effectively, thus allowing two or more light sources in the projection system to be set at an equivalent distance. Close to each other, thereby solving the problem of excessive volume of multi-light source projection systems in the prior art

Embodiment Construction

[0035] An embodiment of the present invention is a projection system, which includes a first light source module 12 , a first flow guiding member 14 and a first fan 16 . Please refer to figure 1 , figure 1 for a schematic diagram of these components. In this embodiment, the first flow guiding member 14 not only has the function of guiding the flow, but also serves as a bracket supporting the first light source module 12 . For ease of illustration, other components in the projection system, such as the housing, circuit board, and optical modules, are not shown in the figure 1 middle.

[0036] figure 1 The arrow 15 in represents the light emitting direction of the first light source module 12 . In practical applications, the first light source module 12 may use a mercury bulb, a tungsten filament bulb, a light emitting diode bulb or other light emitting components as its illuminant. In other words, the concept of the present invention can be applied to projection systems u...

Abstract

The invention provides a projection system, which comprises a light source module, a flow guide member and a fan. The flow guide member comprises a hollow body and at least one part of the light source module is arranged in the body. The body is provided with an air inlet and an air outlet. The fan is close to the air inlet and used for blowing air flow to the air inlet along a first direction. The air flow leaves the air outlet along a second direction and the first direction is different from the second direction. By virtue of the flow guide manner and arrangement of the fan according to the invention, poor heat dissipation is avoided even when two or more light sources in the projection system are closely arranged.

Description

technical field [0001] The present invention relates to a projection system, and more particularly, the present invention relates to a heat dissipation mechanism applied to a projection system. Background technique [0002] In recent years, with the vigorous development of various electronic products, commercial and household multimedia systems are increasingly popular. In most multimedia systems, the most important hardware is a display device for presenting images. How to improve the quality of display devices has always been a topic that manufacturers and designers attach great importance to. [0003] Projection systems have the advantages of small size, easy installation, and large-size images. Therefore, more and more public places, enterprises or home theaters use projection systems as display devices. Since the light in many public places is relatively bright, the brightness of the projection system must be relatively increased, so that the viewer will not feel that...
