Embodiment Construction

[0027] Below, the present invention is further described in conjunction with the preferred embodiments shown in the accompanying drawings.

[0028] A method for providing color-changing light from an existing light source includes the following steps:

[0029] Set up a light source to guide the light beam from the light source to a moving device: the light beam can be directed to the moving device, or directed to the moving device through reflection of a reflecting device (such as a mirror or a spectroscopic filter) or guided by an optical fiber;

[0030] The moving surface of the moving device is divided into several areas with different characteristics; the movement of the moving surface makes these areas face the light beam from the light source in sequence, thereby successively generating light of different wavelengths to form the second light beam : such as a color wheel, which transmits light with different wavelengths through different regions;

[0031] The inventive m...

Abstract

The invention provides a light source capable of providing color change light and a method thereof. The light source comprises a luminous source (2); a moving surface comprises a moving device (1) which is provided with different regions of different characteristics; these regions sequentially face a light beam (41) from the luminous source along with movement to generate light of different wavelengths in sequence for constituting a second light beam (42); in particular, a second luminous source (3) is arranged in the light source for guiding a light beam (43) from the second luminous source and the second light beam (42) to be assembled into an output light beam of the light source; and the luminous source (2) and the second luminous source (3) are controlled, so that the second luminoussource (3) is switched on when the luminous source (2) is switched off when boundary lines among the regions fall into the irradiating range of the light beam (41) from the luminous source. By adopting the light source, the problem of spoke light spots can be solved.

Description

technical field [0001] The present invention is a divisional application of the patent application with the application number 200810067549.7, the application date is May 30, 2008, and the invention title is "a light source capable of providing color-changing light and its method". The present invention relates to a lighting / illumination device and its system, in particular to a light source structure and method for generating varying lighting effects by splitting or combining light beams. Background technique [0002] In the field of image projection, for example (but not limited to) involving rear projection television (RPTV) or front projectors, light source application technology has become more and more mature. While the prior art provides a variable color light source for this field, it continuously optimizes the performance, structure or cost of the light source. [0003] In view of the advantages of solid-state light sources, such as semiconductor light-emitting dio...
