Problems solved by technology

However, when the adhesive is hard adhesive, the adhesive may not easily absorb the vibration generated by the color filter under high-speed rotation, thus causing the color filter to vibrate too much during high-speed rotation. phenomenon, and even greatly increase the noise
Moreover, when the aforementioned vibration reaches a certain level, the color filter will crack or even be damaged.
[0006] In addition, the structure of the color wheel disclosed in U.S. Patent No. 5,868,482 is quite complicated, and the adhesive between the carrying component and the filter is easy to overflow to the light-transmitting area of ​​the filter, causing the filter to be damaged. Contamination problem, and the contaminated part will also reduce the quality of its optical effect

Embodiment Construction

[0033] figure 2 A schematic diagram of a filter set according to a preferred embodiment of the present invention is shown. The filter set 200 of the present invention is composed of one or more filters. The filter set 200 is, for example, a planar circular sheet structure. The filter set 200 can be divided into a light-transmitting area 202 and a filter combining area 204 , and at least one recess 206 is formed in the filter combining area 204 .

[0034] The light-transmitting area 202 is used to provide high transmittance, and changes the color of the passing light after the light passes through. The light-transmitting region 202 is, for example, a region coated with an optical interference filter film.

[0035] The filter combination area 204 is the area where the filter set 200 is combined with the color wheel main body or carrier described later. The recessed portion 206 of the filter joint area 204 is used to provide a combination assembly fixedly connected to the fi...

Abstract

A colour wheel consists of bearing component, filter element set and combination piece as bearing component comprises central axis, the first bearer having at least one concave portion and the second bearer as well as can rotate around central axis, filter element set comprises light transmission area and filter element combination area as central axis is shared by both of filter element set and bearing component with filter element combination area having at least a concave portion, combination piece is located simultaneously in both of concave portions for the first bearer and filter element combination area so as to fix filter element combination area of filter element set at position in between the first bearer and the second bearer.

Description

technical field [0001] The invention relates to a color filter (Color Filter) and a color wheel (Color Wheel) using the filter and a manufacturing method thereof, in particular to a color filter with a method for preventing the filter from escaping and using the color wheel A color wheel for an optical filter and a method for manufacturing the same. Background technique [0002] The known color wheel structure is composed of a carrier and a flat color filter. When the color wheel rotates, due to the action of centrifugal force, the color filter is very easy to shake, deviate, etc., especially when the tolerance between the filter and the carrier is too large, it may even cause the filter damage. [0003] It is known that in order to solve the above-mentioned problems, a color wheel for bonding the filter and the carrier by adhesive is proposed. as figure 1 As shown, the current color wheel 100 is obtained by bonding an adhesive carrier 12, a loop-shaped flat color filter...
