Description

Technical Field

[0001] The present invention relates to the field of laser projection equipment, and in particular to a projection laser light combining module. Background Art

[0002] In the field of laser projector technology, there are many problems that need to be solved urgently. Traditional laser projectors have obvious defects in the beam unification and transmission links. Its focusing lens is difficult to accurately fine-tune, which makes it difficult for the laser emitted by the laser head on the laser array frame to effectively focus into a single beam, which seriously affects the clarity and brightness of the projection and cannot meet the user's demand for high-quality projection effects. In addition, during the long-term beam refraction and transmission process, the existing laser projectors lack a convenient debugging method, and it is difficult to flexibly adjust the refraction angle of the beam, which brings great inconvenience to actual use. In addition, in terms of the use of refractive components, traditional designs usually use a single refractive plate for long-term operation, which is very easy to cause damage to the refractive plate, greatly shortening the service life of the equipment and increasing maintenance costs. At the same time, due to the lack of effective heat dissipation and cleaning mechanisms, the refractive plate is easily affected by heat accumulation during operation, and the dust on the surface will also cause abnormal refraction of the laser beam, resulting in poor projection effects, such as beam dispersion, color deviation and other problems, which seriously affect the user's experience.

Then, under the action of the focusing lens 115, the laser emitted from the laser head 103 can be focused, and then the focusing lens 2 109 can further focus the output laser. After the laser passes through the focusing lens 2 109 and is combined, a laser will be formed. The laser will shine on the refraction module 11, and the refraction module 11 can reflect the laser to the refraction module 2 14, and the refraction module 2 14 can reflect the laser to the refraction module 3 13, and the refraction module 3 13 can reflect the laser to the refraction module 4 12. , the laser can be reflected to the front beam splitter 114 through the refraction module 12, the laser will pass through the front beam splitter 114, and encounter the fluorescent wheel 111 to produce yellow light. Under the action of the rear beam splitter 117, the yellow light will be decomposed into red and green light, and then mixed with the original blue light to produce white light. The white light will encounter the refraction module 5 15 during transmission. Under the action of the refraction module 5 15, the white light can be reflected and exported through the combined light output tube 110.

In the process of refracting and transmitting the light beam for a long time, people can start the electric push rod 1102, and the extension and contraction of the electric push rod 1102 can drive the rotating frame 1101 to deflect, and the deflection of the rotating frame 1101 can deflect the refraction angle of the light beam, which is convenient for people to debug the laser projector in actual use, which is beneficial to practical use. At the same time, the work of the motor inside the installation chamber 1106 can drive the rotating roller 1110 to rotate, and the rotating roller 1110 can drive The rotating sleeve 1104 rotates. When the rotating sleeve 1104 rotates, it can drive the deflection plate 1105 to rotate in a circular manner, so that the deflection plate 1105 in contact with the laser beam can be switched, thereby effectively avoiding the problem of damage to the deflection plate 1105 that may be caused by long-term use of a single deflection plate 1105 for refraction. By intermittently switching the deflection plate 1105, it is beneficial to the long-term use of the deflection plate 1105. In actual use, when the rotating sleeve 1104 is driven to rotate by the rotating roller 1110, the deflection plate 1105 on the back will contact the convex rubber platform 1112 on the storage bin 1109. During the contact process, the coolant stored in the storage bin 1109 can achieve heat dissipation for the deflection plate 1105.At the same time, the cleaning fluff 1111 on the convex rubber platform 1112 can wipe the refraction surface of the refraction plate 1105 to prevent dust from falling on the refraction plate 1105 to affect the refraction of the laser beam or cause the beam to disperse and affect the projection effect. At the same time, the convex rubber platform 1112 is a soft material. When in contact with the refraction plate 1105, the refraction plate 1105 will press the convex rubber platform 1112, thereby agitating the coolant inside the storage bin 1109 and moving the coolant inside, thereby accelerating the heat dissipation, further improving the cooling effect of the refraction plate 1105, reducing heat accumulation, and facilitating practical use.
