Embodiment Construction

[0022] The technical solutions of the various embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] figure 2 A schematic diagram of a light source assembly according to an embodiment of the present invention is shown. Such as figure 2 As shown, the light source assembly 100 includes: a first phosphor wheel system 1 and a second phosphor wheel system 2 . The first phosphor wheel system 1 includes a first phosphor wheel 12, the first phosphor wheel 12 can be irradiated by excitation light, and when the first phosphor wheel 12 rotates, the light irradiated by the excitatio...

Abstract

The invention provides a light source component and a projector. The light source component is provided with more than one fluorescent powder wheel, excitation light transmitted from a first transmission part can motivate a second fluorescent powder layer on a second fluorescent powder wheel to emit the second fluorescent light by adding a transmission part on a first fluorescent powder wheel, thereby sharing the energy born by the fluorescent light motivated by irradiating one fluorescent powder wheel through the excitation light; the working temperature of the fluorescent powder is reduced, the conversion efficiency of the fluorescent powder is improved, and the ageing speed of the fluorescent powder is slowed down. The light source component is applied to the projector.

Description

technical field [0001] The invention relates to light source technology, in particular to a light source component and a projector. Background technique [0002] At present, projection display products are developing rapidly. The mainstream laser projection light source structure generally uses laser to excite phosphors to generate the required laser light to realize the conversion of beam color. [0003] Such as figure 1 As mentioned above, in the prior art, a beam of parallel incident blue excitation light is converged into a light spot through a lens, and a phosphor layer of a required color is coated on the phosphor wheel. When rotating, the phosphor layer is irradiated by the blue excitation light and converted into a fluorescent beam of the corresponding color of the phosphor, part of the fluorescent light is collimated into a parallel beam through the lens, and returns along the original optical path, and part of the fluorescent light is reflected by the substrate of...
