Composite light module, and projecting unit

Abstract

A light combination module is prepared for setting the first and the second filters in an angle-cross mode to form the first region, the second region, the third region and a light combination region; setting the first region to be opposite to the second one and the third region to be opposite to light combination region; setting the first light source in the first region for emitting the first light beam being reflected to light combination region via the first filter; setting the second light source in the second region for emitting the second light beam being reflected to light combination region via the second filter. The projection device applying said light combination module is also disclosed.

Description

technical field [0001] The present invention relates to a light combination module and a projection device, in particular to a light filter with intersecting arrangement, which can save space and have greater structural strength, which can improve the application options of the light combination module and improve performance and Applied light combination module and projection device. Background technique [0002] Since light-emitting diodes began to be commercialized in the 1960s, due to their advantages of high shock resistance, long life, and small size, their application range has gradually spread to various items in daily life, such as lighting devices and display devices as light sources or Backlight. In a display device, LEDs need to be combined with other optical components to produce full-color visual effects, and one of the important optical components is a dichroic filter. The filter is made of a glass plate coated with various dichroic films. When the light pas...

Problems solved by technology

[0005] Although the combined light module 1 can achieve the effect of combined light, because its two filters are set separately, it requires a larger space, and the strength of its structure is also smaller; in addition, the light combined module 1 The photosynthetic area can only be fixed in the same direction, and the selectivity of the application is low

In addition, it does not disclose how to apply it to other optical devices (such as projection devices), so that the light combination module 1 cannot perform other functions except light combination

[0006] It can be seen that the above-mentioned existing light-combining module and projection device obviously still have inconvenience and defects in structure and use, and need to be further improved urgently.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general products do not have a suitable structure to solve the above-mentioned problems. This is obviously related. The problem that the industry is eager to solve
