[Prior Art] The projection system is a common type of optoelectronic display device, and is widely used in living entertainment, academic presentations, etc. According to its display principle, the projection system can be divided into cathode ray tube (CRT) projection system, liquid crystal display (LpD) projection system, digital light processing (DLP) projection system and stone. Liquid crystal 〇n Silicon (LCoS) projection system, etc. Among them, DLP projection system is popular among consumers because of its high brightness, vivid color, high response rate, and light and thin device. The main market for products. The DLP projection system uses a Digital Micro-mirror Device (DMD) to modulate the light source and then image it onto the screen via a projection optical system. Among them, single- or dual-chip DMD projection systems usually use a Color Wheel to color-separate the light source, add color components to the modulated light, and realize color display. A conventional color wheel generally includes a motor and a filter, and the filter is fixed to the motor in a subsequent manner. During the use of the filters, the light source of the light source can be transmitted through the filter film to the subsequent portion of the filter, resulting in deterioration of the bonding quality of the light-emitting sheet and subsequent loosening or falling off.

[0035] The motor 10 includes a rotor 12 and a stator (not shown) composed of an electromagnetic element (not shown) such as a magnet, a silicon steel sheet, and a wire winding. When the motor 1 starts, the electromagnetic element generates a rotating magnetic field. The rotor 12 is driven to rotate. The rear portion 11 is disposed in the rotor 12. In operation, the rear portion 11 drives the filter 20 adjacent thereto to rotate with the rotor 12. The rotor 12 of the present embodiment is a rotating shaft. The connecting portion 11 is a turntable provided on the rotating shaft, and the filter 20 is then disposed on the side opposite to the motor 10 of the turntable. • The bottom of the motor 10 is provided with two fins 13 . The fins 13 are provided with through holes 14 , and the through holes 14 are sleeved on the fixing posts of the color wheel mounting portion (not shown), so that the color wheel 100 can be fixed. .

The annular transparent substrate 21 of the present embodiment is made of glass. The glass surface is divided into four sectors, and respectively coated with a filter film 23 for filtering red, green, blue and white light. Of course, the calendering sheet 20 The arrangement is not limited to the embodiment, the annular transparent substrate may adopt other transparent substrates that meet the conditions, or the setting of the coating may be changed, or even a plurality of fan-shaped filters may be combined. Filter 20. [0037] The filter 20 is directly attached to the splicing portion, thus eliminating the need for a carrier for the previous color wheel and reducing the process of attaching the filter to the carrier. In turn, the cost of the color wheel is reduced. [0038] The light blocking sheet 30 needs to have the following characteristics: 1) can block the shooting to the next 096104073 form number Α 0101 page 9 / total 26 pages ' 1003171159-0 1345674 100 years of May 16 nuclear replacement page The light of 11 avoids the deterioration of the bonding quality of the adhesive portion 11; 2) the thermal expansion coefficient of the filter 20 is substantially equal, and the thermal stress is prevented from damaging the filter 20. Therefore, in this embodiment, a reflective light blocking sheet is used as the light blocking sheet 30, which has high-grade light capability and good light blocking effect. In addition, in this embodiment, the light-shielding sheet 30 is made of the same material as the filter 20, and thus the light-blocking sheet 30 and the filter 20 have the same thermal expansion coefficient, thereby achieving thermal coupling between the two.

In addition, during the operation of the color wheel 300, the filter 20 and the connecting portion 11 will also undergo a heat generation and cooling process to generate thermal stress. Therefore, the color wheel 100 of the embodiment further includes a thermal stress buffer layer 40 disposed between the filter 20 and the bonding portion 11 for buffering the thermal stress received by the filter 20. The thermal stress buffer layer 40 is provided on the bonding portion 11 by means of bonding. The thermal expansion coefficient of the glass material used in the filter 20 of the present embodiment is larger than the thermal expansion coefficient of the steel material used in the subsequent portion 11 in the range of the operating temperature variation of the color wheel 300. The thermal stress buffer layer 40 has a coefficient of thermal expansion that is less than or equal to a coefficient of thermal expansion of the filter 20 and greater than or equal to a coefficient of thermal expansion of the tab portion 11. 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 I.
