Embodiment Construction

[0072] In order to understand the technical features and beneficial effects of the present invention in detail, and to realize them according to the content, in the following, the preferred implementation as shown in the accompanying drawings will be further described in detail:

[0073] see figure 1 , figure 2 and image 3 As shown, the first preferred embodiment of the composite optical color wheel device for projectors of the present invention includes: a substrate 10, a light-transmitting material 20, a counterweight sheet 30, a glass phosphor 40 and a coating layer 50 ; the composite optical color wheel device for a projector of the present invention is installed on a motor 60 to form a color wheel module and is driven by the motor 60 to rotate.

[0074] Such as figure 2 and image 3 As shown, the substrate 10 is an opaque circular plate. The substrate 10 has an axis and includes a set hole 11 and a through hole 12. The set hole 11 is provided through the axis of t...

Abstract

The invention discloses a projector combined type optical color wheel device which comprises a substrate, a light transmission material, a counterweight sheet material and a glass phosphor body. The glass phosphor body comprises a light transmission area. The light transmission material is fixedly arranged in the light transmission area; the counterweight sheet material is attached on the light transmission material; and the glass phosphor body neighbors the substrate. According to the invention, the density of the counterweight sheet material is different from that of the light transmission material and the light matting property is unlike that of the substrate so as to achieve the effect of both counterweight and time sequence marking and solve the problem with the increase in the working procedures when needed to be externally provided with a counterweight and time sequence marking and the problem with the proneness to come off during the high speed rotation of a color wheel by providing a projector combined type optical color wheel device with simplified procedures and enhanced production performance.

Description

technical field [0001] The invention relates to a device or equipment for photographing, projecting or viewing, in particular to a composite optical color wheel device for a projector that can simplify the production procedure. Background technique [0002] Most of the existing projectors use the digital light processing technology (DLP) developed by Texas Instruments, which uses light to irradiate a rotating color wheel to achieve the purpose of color separation, and then uses the principle of persistence of vision to make human vision Combinations of various colors are produced. [0003] Such as Figure 10 , Figure 11 and Figure 12 As shown, the existing color wheel 70 includes a silica gel phosphor 71 and a light-transmitting material 73; wherein, the silica gel phosphor 71 forms more than one color area 711 on the surface by coating and hollows out A light-transmitting area 712 is formed, and the light-transmitting material 73 is embedded in the light-transmitting a...
