Embodiment Construction

[0024] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0025] figure 2 A schematic diagram showing Embodiment 1 of the color wheel according to the present invention, image 3 show figure 2 A schematic top perspective view of the color wheel. See in conjunction with 2 and image 3 , it can be seen from the figure that the color wheel in Embodiment 1 is a disk-shaped color wheel, and the color wheel includes: a substrate 10 , a light-transmitting layer 30 and a wavelength conversion layer 50 stacked in sequence. The color wheel also includes a motor 1 connected to the bottom of the substrate 10 , and the color wheel can be driven to rotate by the motor 1 .

[0026] The wavelength conversion layer 50 includes a wavelength conversion material f...

Abstract

The invention provides a color wheel, a light source, a projector and a manufacturing method of the color wheel, wherein the color wheel comprises a base plate (10), a wave length transfer layer (50), and a photic layer (30) in a sequentially stacking mode. In the direction which is perpendicular to a stacking direction, the edge of the wave length transfer layer (50) extends out of or coincides with at least one edge of the base plate (10) and the photic layer (30). An outer glue layer (70) is arranged on the outer side of the outer edge of the wave length transfer layer (50) in an enclosure mode. The color wheel, the light source, the projector and the manufacturing method of the color wheel effectively solve the problems that in the prior art, glue adding amount of the color wheel is difficult to control and glue adding operation is low in efficiency.

Description

technical field [0001] The present invention relates to the technical field of color wheels, in particular, to a color wheel, a light source, a projector and a manufacturing method of the color wheel. Background technique [0002] The role of the color wheel in a DLP (Digital Light Processing) projector is the separation and processing of colors. The separation and filtering of colors by the color wheel is achieved through the high-speed operation of the color wheel. [0003] Disc-shaped color wheels of the prior art such as figure 1 As shown, the color wheel includes a substrate 10', a wavelength conversion layer 50' and a light-transmitting layer 30' stacked in sequence. The light-transmitting layer 30' and the substrate 10' are concentric and equal circles, and the wavelength conversion layer 50' is in the shape of a ring with a through hole in the center. The through hole is provided with a central glue 90', and the central glue 90' ​​is fixedly connected to the light-t...
