Problems solved by technology

Due to the structural limitation of the single substrate of the traditional fluorescent pink wheel, it is difficult to realize multiple optical functions in the same fluorescent pink wheel at the same time, resulting in the limitation and inflexibility of the optical path design
At the same time, for the current traditional fluorescent pink wheel manufacturing process, especially the multi-color segment fluorescent pink wheel, there are certain difficulties in the precise control of the position, gap, shape and other requirements of the color segment, as well as the subsequent part of the manufacturing process, resulting in The process of the fluorescent pink wheel is complicated, the overall light intensity decreases, and the chromaticity and color temperature have deviations. At the same time, this will also require higher production costs.

Embodiment 1

[0040] figure 1 Shown is Example 1 of the present invention, which is assembled from three aluminum substrate fans with a silver-coated film with a thickness of 0.5mm, and red, yellow, A fluorescent pink wheel layer assembled after green three different fluorescent pink segments. Three pieces of aluminum substrate fans 103, 106, 107 with different angles but with a sum of angles of 360° are made by silver-plated film (high reflection) process on aluminum sheet raw materials, and by cutting and other mechanical and chemical related methods. Then use methods such as printing, dispensing, and spraying to coat fluorescent pink segments 201, 202, and 203 on each substrate segment respectively. Through a specific jig, three aluminum substrate segments 103, 106, and 107 coated with fluorescent pink segments are assembled. Forming an outer diameter of 55mm and an inner diameter of 12mm circular fluorescent pink disc layer.

[0043] figure 2Shown is Example 2 of the present invention, which consists of a diffuser substrate fan 104 with a haze of 100% and a thickness of 1 mm, and two aluminum sheets with a thickness of 0.8 mm and a reflectivity of 95% with an aluminum-coated metal film on the surface The substrate segments 101, 108 are assembled. A fluorescent pink wheel layer formed by coating different fluorescent pink segments 201, 202 on two aluminum substrate segments coated with metal film, and then assembling with the diffuser substrate segment 104. The diffuser 104 and the aluminized film-coated aluminum plate substrate fan pieces 101 and 108 are made by the aluminized film process on the raw material of the aluminum sheet, and through mechanical and chemical related methods such as cutting. Then use printing, dispensing, spraying, etc. to coat the fluorescent pink segments 201 and 202 on the aluminum substrate segments 101 and 108 respectively. Through a specific jig, the diffuser segment...

Embodiment 3

[0046] image 3 Shown is Embodiment 3 of the present invention, which is assembled from 6 pieces of glass fans with a thickness of 0.7mm, an angle of 60°, an outer circle diameter of 50mm, and an inner circle of less than 12mm. A fluorescent pink wheel layer assembled after coating different fluorescent pink segments 201, 202, and 203 on six glass fan pieces. By coating the glass surface with a high-transparency blue film, and through mechanical processing such as machine cutting, 6 glass fan pieces 102 with an angle of 60° are formed, and then printing, dispensing, spraying, etc. are applied to each glass fan. Fluorescent pink segments 201, 202, and 203 are respectively coated on the sheet. By means of a specific jig, 6 pieces of glass segments 102 coated with fluorescent pink segments are assembled to form a fully transparent circular fluorescent pink wheel layer with an outer diameter of 50 mm and an inner diameter of 12 mm.

Abstract

Disclosed are a fluorescent powder color wheel and a manufacturing method thereof. A plurality of substrates are assembled to form the fluorescent powder color wheel, and coated substrates and substrates with surfaces coated with fluorescent powder are assembled by the aid of a jig. By the aid of a novel fluorescent powder color wheel structure and the manufacturing method of the fluorescent powder color wheel, multiple functions of a single fluorescent powder color wheel are applied in a combined manner, and the novel fluorescent powder color wheel and a light source using the same are provided to realize flexible combined application of optical path design of a projection system and meet the requirements of an LED (light-emitting diode) light source and a laser light source for exciting light intensity and chromaticity.

Description

[0001] technical field [0002] The invention relates to the technical field of light sources for lighting and projection display, in particular to a structural design and a manufacturing method of a fluorescent pink wheel assembled from one or more substrate segments in the field of projection display. [0003] Background technique [0004] Now, more and more projection displays mainly choose to use LED (Light Emitting Diode) or LD (Laser Diode) as the display light source. One of the modes is to directly use the multi-color excitation light source to emit light of different wavelengths such as red, green or blue. As a light source to achieve color display; the other is to use a red or green or blue as a light source, and then use it to excite and convert the other two primary colors, and finally realize color projection display by modulating the optical path. For example, U.S. Patent No. 7,547,114B2 proposes a method for generating high-brightness time-sequence color ligh...
