Problems solved by technology
[0008] Even so, as everyone knows, light-emitting diodes provide extremely divergent light beams, which are neither concentrating ellipsoid lights nor parabolic lights that provide parallel light. Therefore, when the light beams of light-emitting diodes are projected on the mirror wheel 12, they will occupy a considerable area. area, the above-mentioned measures of driving the light bulb in advance may not be able to achieve the desired result; in addition, there are many junction areas on the mirror wheel 12, and for avoiding each junction, there is a considerable area on the mirror wheel 12 from the beginning that cannot be reached. is utilized, this situation is the same as shortening the required continuous luminous flux A-section "flat peak section", and increasing the unnecessary B-section "narrow valley section", that is, increasing the discontinuity of luminous flux, greatly Minimally reduce the use efficiency that the mirror wheel 12 can normally provide

Embodiment Construction
[0045] The first embodiment of the present invention is a display system 3 , as shown in FIG. 3A , the display system 3 includes a light source system 31 , a light guide system 33 and an imaging system 35 . In this embodiment, the display system 3 is a digital light processing (DLP) projector.
[0046] The light source system 31 is used to provide light required for imaging, and includes a first light source module 311 and a second light source module 321 . The first light source module 311 includes a mirror wheel 313 , two secondary light source modules and a controller (not shown in the figure).
[0047] With reference Figure 5The mirror wheel 313 has a central shaft 310 and a body portion 312. In this embodiment, the body portion 312 is disc-shaped, for example, a disc with a diameter of 5 cm (the diameter can be adjusted according to actual needs). The main body portion 312 is disposed on the outer peripheral edge of the rotating shaft. The main body portion 312 include...

Abstract
The invention provides a light source module and a display system using the light source module. The display system comprises a light source system, a light guiding system and an imaging system. The light source system comprises a first light source module and a second light source module, wherein the first light source module provides a first color light, and the second light source module provides a plurality of color lights with different colors from the first color light. The light source system lights the first color light and the color lights with different colors to provide to the light guiding system according to the prearranged integration time sequence, and the light rays generated by the light source system can be guided to the imaging system by the light guiding system to perform the imaging at proper time.
Description
technical field [0001] The present invention relates to a light source device, in particular to a module using a plurality of light emitting diodes (Light Emitting Diode, LED) as a light source, and a display system using the light source module. Background technique [0002] U.S. Patent Application No. 11 / 081,825 discloses a light-emitting structure using light-emitting diodes as a light source. In the state of non-continuous lighting, a higher current is input to drive light. Based on this structure, a light source module and a projection using the light source module are established. system. [0003] Referring to FIG. 1 , the light source module 1 includes a first LED 111 , a second LED 112 , a mirror wheel 12 , and a power control device (not shown in the figure). The two light emitting diodes 111 , 112 are arranged such that their light emitting paths are substantially perpendicular to each other, and the mirror wheel 12 is arranged between the two light emitting diode...
