Light source module and projection display

Abstract

The invention discloses a light source module that includes a case, a light source, a first wind sending device used to send first flow, a second wind sending device used to send second flow, and a diversion component that has the first diversion section and the second diversion section. The case has a wind outlet, and the light source, first wind sending device, second wind sending device and diversion component are set in the case. The first diversion section is at the same side of the light source and the second diversion section is located at the upper of the light source. The first flow flows to first diversion section after passing through light source and guided by the second diversion section flowing from the front of light source to back of the light source, and exhausted from wind outlet after mixing with the second flow.

Description

Technical field [0001] The invention relates to a light source module and a projection display device, in particular to a light source module and a projection display device equipped with a fan. Background technique [0002] In modern society, with the advancement of optical projection technology, projection display devices capable of outputting high image quality, high resolution and large screens have been developed and used in large numbers. In order to obtain a high-brightness projection screen, the projection display device must use a high-power light source. However, a high-power light source usually generates a lot of heat during use, so it must be equipped with an appropriate heat dissipation design to prolong the service life and display quality of the projection display device. [0003] figure 1 Shown is a top view of the bulb in a conventional projection display device. Please refer to figure 1 In the existing projection display device, the bulb 100 is arranged in t...

Problems solved by technology

However, in the above-mentioned existing design, the airflow 122 is immediately affected by the airflow 132 immediately after leaving the air guide 140, and is directly discharged from the air outlet 112 next to the area A, and has no chance to interact with the low-temperature airflow 132. mix thoroughly

In this way, a local high temperature will be generated at the air outlet 112 next to the area A, and in some cases even a high temperature of 102°C will be generated, which not only fails to meet the requirements of safety regulations, but also easily causes harm to users.
