Problems solved by technology

[0003] refer to figure 1 , the holder (holder) 11 of the existing integrating column 10 is a hollow cylinder, and there is no adjustment mechanism design when the integrating column 10 is fixed relative to the light source 12, that is to say integrating column 10, holder 11 and light source 12 The relative positions of the three are fixed and cannot be changed, so that the angle of the light beam emitted by the light source 12 is limited by the size of the holder 11, that is, the error of the optical path cannot be corrected; and the holder 11 of the hollow cylinder requires a large assembly space

Embodiment Construction

[0013] The aforementioned and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of a preferred embodiment with reference to the drawings.

[0014] Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

[0015] refer to figure 2 and image 3 , the preferred embodiment of the integrating column fixing device with adjustment function of the present invention is suitable for relatively fixing an integrating column 21 on a light source module 22. In this embodiment, the light source module 22 is based on a plurality of light emitting diodes (LEDs) ) as an example, which includes R, G, B (red, green, blue) LEDs. Since the three primary colors LEDs have high color saturation and directivity, the lamp reflector (not shown in the figure) can be omitted. The color wheel (color wheel) (no...

Abstract

The present invention provides an integral column fixing device with regulation function. It is applicable to make an integral column be relatively fixed on a light source module. Said fixing device includes a self-body and several fixing pieces. Said self-body surface has several fixing holes correspondent to the fixing pieces, the integral column can be fixed on said light source module by means of fixing holes and fixing pieces.

Description

technical field [0001] The invention relates to an integrating column fixing device, in particular to an integrating column fixing device with adjustment function. Background technique [0002] In the projection device, the integrated rod is an important optical element, which is arranged on the light path to homogenize the light. Generally, the common integrated rod can be roughly divided into solid integrated rod and hollow integrated rod ( hollow integrated rod) two kinds. The solid integrating column uses the principle of total internal reflection (TIR) ​​between the material and the air, while the hollow integrating column uses glass substrates to overlap and adhere to each other to form a hollow column, and the inner wall is coated with a high-reflectivity coating to make it easier to enter the integrating column. The light beam can be reflected multiple times by the coating, so as to achieve the purpose of homogenizing the light beam. [0003] refer to figure 1 , t...
