[0002] A projector is a device that can project images or videos onto a screen, and can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play corresponding video signals. Projectors are widely used in homes, offices, schools, and entertainment venues.

[0003] For existing projection equipment, if clear images and a large screen are desired, the internal structure of the projector will be relatively complex and the structure will also be large, which is not suitable for use in homes and office places. Moreover, the imaging method of the projector utilizes the properties of light, and the problem with using light imaging is that the process of generating light is an exothermic process, and a large amount of heat will be generated during this process. However, the existing projectors have poor cooling effects on each dispersion plate during the light processing process, resulting in poor projection effects of the projectors and affecting the service life.

Specific embodiments

[0040] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand the other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0041] Please refer to Figures 1 - 5 , and now a direct projection type projector optical machine disclosed by the present utility model will be described. The present utility model is composed of six parts, as shown in Figure 1 , including a camera lens 1, a power-on component 2, a cooling component 3, a radiator 4, an installation housing 5 and an imaging component 6. The interior of the installation housing 5 is a hollow structure, and the imaging component 6 is installed in the hollow structure. The radiator 4 is installed on the side plate of the installation housing 5, the cooling component 3 is installed on the installation housing 5, the camera lens 1 is installed on the side plate of the installation housing 5, the camera lens 1 is arranged on the opposite side of the radiator 4, the power-on component 2 is installed on the outer surface of the side wall of the installation housing 5, and the power-on component 2 is connected to the radiator 4 and the cooling component 3 through wires.

[0042] When the utility model is in use, the PCB board drives the energizing component 2 to supply power to the LED light source 8. The LED light source 8 generates a light beam, and the light beam is concentrated after passing through the reflecting cup 61. Then, the light is reflected to the homogenizing Fresnel lens 62 through the reflecting surface of the reflecting cup 61. The homogenizing Fresnel lens 62 can effectively focus and evenly distribute the incident light beam. The evenly divided light enters the polarizing lens 63. By the polarizing lens 63, the utilization rate of light is improved and scattering is reduced, so that the projected image has a three-dimensional visual effect, and the image quality can also be optimized. After passing through the polarizing lens 63, the light enters the LCD panel 64, and imaging is performed through the LCD panel 64. The formed image is emitted in the form of light to the imaging Fresnel lens 65 for integration, and then presented to the outside through the camera lens 1. Through the setting of the imaging Fresnel lens 65, the light is focused and evenly divided, making the projected image clearer. Finally, the light irradiates on the wall or the curtain to complete imaging. During the imaging process, the fan in the radiator 4 will discharge the heat generated by the LED light source 8, and at the same time, the fan in the air supply housing 35 will suck in cold air, and then the cold air blows onto the surfaces of each plate body in the imaging component 6 for cooling.

[0043] In a specific embodiment, such as Figure 2 , the installation housing 5 includes a second top plate 51, a rectangular groove 52, an installation groove 53, a housing 54, a lower clamping block 55, a round rod 56, an insertion block 57, a first top plate 58 and an upper clamping block 59. A plurality of round rods 56 are installed inside the housing 54, and a plurality of rectangular grooves 52 are formed on the inner surface of the housing 54. The imaging component 6 is inserted into the rectangular groove 52. The lower clamping block 55 is installed on the side of the housing 54, the first top plate 58 is installed above the housing 54, the upper clamping block 59 is installed at the end of the first top plate 58, and the insertion block 57 is installed on the side of the upper clamping block 59. The insertion blocks 57 are arranged in pairs and are inserted into the lower clamping block 55. The camera lens 1 is installed between the upper clamping block 59 and the lower clamping block 55. The second top plate 51 is installed above the housing 54, and a connection groove is formed between the second top plate 51 and the first top plate 58.
