Problems solved by technology

If there is an error in the positioning of the light source, it will cause problems such as brightness attenuation and poor imaging quality uniformity.
[0004] In order to make the illuminated area generated when the light from the light source is projected onto the imaging element coincide with the imaging element, the current projector adds an adjustment device to the optical system to adjust the light path. However, the addition of the adjustment device will undoubtedly increase the volume of the projector. Contributes to the miniaturization of the projector

Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0013] see figure 1 , is the projector 100 provided by the present invention. The projector 100 includes at least one light source module 10 , a first optical element 20 , a lens 30 , a second optical element 40 , an imaging element 50 , a lens module 60 and an optical machine base 70 . The light source module 10 , the first optical element 20 , the lens 30 , the second optical element 40 , the imaging element 50 , and the lens module 60 are sequentially fixed in the optical machine base 70 along the optical path direction.

[0014] The imaging element 50 of the projector 100 may adopt DLP (Digital Light Processor) technology, or LCD (Liquid Crystal Display) technology or LCOS (liquid crystal on silicon) reflective liquid crystal technology. In this embodiment, the imaging device 50 is an LCOS panel.

[0015] In this embodiment, the optical machine base 70...

Abstract

A light source module comprises a light source component, a radiating element, a light source base and a locking element. The light source base comprises an accommodating hole in which the light source component is accommodated. The locking element fixes the radiating element on the light source base. The light source component is capable of sliding with respect to the radiating element in a first direction, the radiating element is capable of sliding with respect to the light source base in a second direction, the first is perpendicular to the second direction, the first direction and the second direction are arranged on the plane where the optical axes of the light beams projected by the light source module are perpendicular to each other, and the locking element fixes the relative position of the light source component, the radiating element and the light source base. The light source module provided in the invention is capable of adjusting the position of the light source component during the assembly so that the lighting area of the light source component reaches an optimal illumination position, and finally fixes the light source component so as to ensure that the lighting area of the light source component reaches the optimal illumination position. In addition, the invention further provides a projector.

Description

technical field [0001] The invention relates to a light source module and a projector using the light source module. Background technique [0002] At present, with the home use of projectors, there are more and more products on the market. However, in order to manufacture a projector with high imaging quality, it is often necessary to improve the performance of the projector in all aspects. [0003] However, when the light emitted by the light source of the projector is irradiated onto the imaging element through the optical system, the optical path from the light source to the imaging element must be correct, so that the illuminated area generated when the light is projected onto the imaging element coincides with the imaging element, so that the image in the imaging element The image can be completely projected on the screen through the lens module. If there is an error in the positioning of the light source, it will cause problems such as brightness attenuation and poor...
