Description

Technical Field

[0001] The utility model relates to the field of projectors, in particular to an energy-saving long-life LED projector. Background Art

[0002] A projector, also known as a projector, is a device that can project images or videos onto a screen or wall. It is mainly connected to computers, VCDs, DVDs, BDs, game consoles, DVs, etc. through different interfaces to play corresponding video signals. The projector uses the convex lens imaging principle to project transparent objects onto the screen to form an enlarged image.

[0003] Existing projectors usually use high-energy bulbs to project images during use. Since high-energy bulbs generate a lot of heat when working, the projector may overheat, affecting the projection effect. In addition, electronic components will age faster when working in a high-temperature environment, resulting in performance degradation and shortening the overall service life.

[0004] Therefore, in view of the fact that the above-mentioned existing projectors use high-energy bulbs to project images during use, which generates a large amount of heat and causes the projector to overheat. The high temperature environment accelerates the aging of internal components and affects the overall service life. An energy-saving and long-life LED projector can be designed to reduce the power consumption of the lamp source, save energy, reduce the heat generation of the projector, and maintain stable operation of the projector. Utility Model Content

[0005] In order to overcome the problem that existing projectors use high-energy bulbs to project images during use, which generates a lot of heat and causes the projector to overheat, the high temperature environment accelerates the aging of internal components and affects the overall service life.

[0006] The technical solution of the utility model is: an energy-saving and long-life LED projector, including a shell, an energy-saving adjustment component and a heat dissipation component; one end of the shell is equipped with an energy-saving adjustment component for replacing and adjusting the light source for projection, and the rear end of the shell is equipped with a heat dissipation component for monitoring the internal temperature of the projector and adjusting the heat dissipation effect; the energy-saving adjustment component includes a positioning frame, an LED light source, a rack, a drive module, a gear, a threaded ring, a fixing frame, and a clamping rod; one end of the shell is equipped with a positioning frame, and the interior of the positioning frame is equipped with an LED light source.

[0007] Preferably, by using LED light sources for projection, the frequency and cost of replacing bulbs are reduced. At the same time, the LED light source has a slower attenuation rate and lower power consumption, which saves a lot of energy. The LED light source does not generate a lot of heat during the light-emitting process, which reduces the heat generation of the projector, avoids overheating and short-circuit damage of the projector, and maintains stable operation of the projector. Secondly, a temperature sensor is used to monitor the internal temperature, and the control module is driven to adjust the fan heat dissipation according to the actual temperature conditions, increasing the air flow, avoiding damage to the projector caused by temperature fluctuations, and when the temperature drops to a certain level, the control module will reduce the fan speed to avoid unnecessary energy waste.

[0008] Preferably, the fixing bracket is located inside the shell, and a threaded ring is provided at one end of the fixing bracket. The positioning frame is fixed to the shell thread through the threaded ring. By using the threaded ring to connect the positioning frame to replace the light source, replacing the LED light source becomes simpler and faster, avoiding the complicated disassembly process, reducing the difficulty of replacement, and at the same time ensuring that the LED light source is precisely aligned with the optical system of the projector, thereby improving the clarity and color reproduction of the projection image.

[0009] Preferably, a rack is provided on the outer wall of the positioning frame, a driving module is provided at one end of the outer shell, a driving rod is provided at one end of the driving module, a gear is sleeved on the outer wall of the driving rod, and the gear is meshed with the rack. The rotation of the light source is adjusted by connecting the gear to the rack through the driving module, thereby optimizing the distribution of light in the projection lens, making the projection picture clearer and the color more accurate, improving the projection effect, and providing a more flexible projection method in different usage scenarios, thereby improving the practicality of the projector.

[0010] Preferably, a plurality of groups of card rods are provided around the outer end of the fixing frame, and a card slot for accommodating the card rods is opened at one end of the outer shell. The fixing frame is fixed to the outer shell by the card rods. By using the card rods to connect the fixing frame and the outer shell for card fixing, a more stable fixing effect is provided, ensuring a close fit between the fixing frame and the outer shell, reducing the risk of loosening, falling off and damage due to vibration, and extending the service life of the projector.

[0011] Preferably, the heat dissipation assembly includes a control module, a fan, a docking frame, an output plate, fins, a transmission tube, a heat conducting plate, a connecting block, a heat pipe, and a temperature sensor. The control module is located at the rear end of the shell, and a connecting block is provided at the outer end of the control module. Multiple groups of heat pipes are provided inside the connecting block. Docking frames are provided at both ends of the heat pipes, and fins are provided inside the docking frames. By using a heat pipe to connect the two groups of fins, the heat dissipation area is increased to assist heat dissipation, so that more heat can come into contact with the air and dissipate into the environment, avoiding excessively high temperature that affects its brightness and color, thereby ensuring stable operation of the projector.

[0012] Preferably, a fan is provided on the inner wall of the docking frame, an output plate is provided on the side of the fan away from the fins, a heat conducting plate is provided on the outside of the output plate, and a transmission tube is provided between the output plate and the heat conducting plate. The fan is combined with the output plate to connect the heat conducting plate to dissipate heat from the internal heating parts of the projector, accelerate the air flow, and take away the heat generated inside the projector. The heat conducting plate can quickly conduct the heat on the heating parts to other areas, making the heat distribution more uniform, and the auxiliary fan dissipates it into the air, ensuring that the internal heating parts can maintain a low operating temperature, thereby improving the heat dissipation efficiency of the projector.

[0013] Preferably, a temperature sensor is provided at the lower end of the control module, and the temperature sensor is electrically connected to the control module and the fan. By using the temperature sensor to monitor the internal temperature, the control module is driven to adjust the fan heat dissipation according to the actual temperature conditions, thereby increasing the air flow and avoiding damage to the projector caused by temperature fluctuations. When the temperature drops to a certain level, the control module will reduce the fan speed to avoid unnecessary energy waste.

[0014] Beneficial effects of the utility model:

[0015] 1. Compared with traditional projectors, the use of LED light sources for projection reduces the frequency and cost of replacing bulbs. At the same time, the LED light source has a slower decay rate and lower power consumption, saving a lot of energy. In addition, the LED light source does not generate a lot of heat during the light emission process, which reduces the heat generation of the projector, avoids overheating and short circuit damage, and maintains the stable operation of the projector. Secondly, a temperature sensor is used to monitor the internal temperature. According to the actual temperature conditions, the control module is driven to adjust the fan heat dissipation, increase the air flow, and avoid damage to the projector caused by temperature fluctuations. When the temperature drops to a certain level, the control module will reduce the fan speed to avoid unnecessary energy waste.

[0016] 2. When heat dissipation is achieved through a fan combined with a heat conduction plate, a heat pipe is used to connect two sets of fins to increase the heat dissipation area to assist in heat dissipation, accelerate air flow, and allow more heat to come into contact with the air and dissipate into the environment. The heat conduction plate can quickly transfer the heat from the heating components to other areas, making the heat distribution more even, ensuring that the internal heating components can maintain a lower operating temperature, improving the overall heat dissipation effect, and ensuring the stable operation of the projector.

[0017] 3. Use the drive module to connect the gear drive rack to adjust the rotation of the light source, optimize the distribution of light in the projection lens, make the projection picture clearer, the color more accurate, improve the projection effect, and provide a more flexible projection method in different usage scenarios, thereby improving the practicality of the projector. At the same time, the clamping rod connects the fixing frame and the shell for clamping and fixing, providing a more stable fixing effect, ensuring a close fit between the fixing frame and the shell, reducing the risk of loosening, falling off and damage due to vibration, and extending the service life of the projector.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] See also Figure 1-Figure 4 The utility model provides an embodiment: an energy-saving and long-life LED projector, including a housing 1, an energy-saving adjustment component and a heat dissipation component; one end of the housing 1 is equipped with an energy-saving adjustment component for replacing and adjusting the light source 202 LED for projection, and the rear end of the housing 1 is equipped with a heat dissipation component for monitoring the internal temperature of the projector and adjusting the heat dissipation effect. The energy-saving adjustment component includes a positioning frame 201, an LED light source 202, a rack 203, a drive module 204, a gear 205, a threaded ring 206, a fixing frame 207, and a clamping rod 208. A positioning frame 201 is provided at one end of the housing 1, and an LED light source 202 is provided inside the positioning frame 201.

[0025] See also Figure 1-Figure 2In this embodiment, the fixing frame 207 is located inside the housing 1. A threaded ring 206 is provided at one end of the fixing frame 207. The positioning frame 201 is threadedly fixed to the housing 1 through the threaded ring 206. By connecting the positioning frame 201 with the threaded ring 206 to replace the light source 202 LED, it becomes easier and faster to replace the LED light source 202, avoiding the complicated disassembly process and reducing the difficulty of replacement. At the same time, it ensures that the LED light source 202 is accurately aligned with the optical system of the projector, thereby improving the clarity and color reproduction of the projected image. The positioning frame 201 A rack 203 is provided on the outer wall of the housing 1, a driving module 204 is provided at one end of the driving module 204, a driving rod is provided at one end of the driving rod, a gear 205 is provided on the outer wall of the driving rod, and the gear 205 is meshed and connected with the rack 203. By adopting the driving module 204 to connect the gear 205 to drive the rack 203 to adjust the rotation of the light source 202LED, the distribution of light in the projection lens is optimized, so that the projection picture is clearer and the color is more accurate, the projection effect is improved, and a more flexible projection method is provided in different usage scenarios, thereby improving the practicality of the projector.

[0026] See also Figure 1-Figure 3 In this embodiment, a plurality of groups of clamping rods 208 are arranged around the outer end of the fixing frame 207, and a clamping slot for accommodating the clamping rods 208 is opened at one end of the shell 1. The fixing frame 207 is clamped and fixed to the shell 1 through the clamping rods 208. By using the clamping rods 208 to connect the fixing frame 207 and the shell 1 for clamping and fixing, a relatively stable fixing effect is provided, ensuring that the fixing frame 207 and the shell 1 are tightly fitted, reducing the risk of loosening, falling off and damage due to vibration, and extending the service life of the projector. The heat dissipation component includes a control module 301, a fan 302, a docking frame 303, an output plate 304, a fin 305, and a transmission tube 306. 06. Heat conducting plate 307, connecting block 308, heat pipe 309, temperature sensor 310. The control module 301 is located at the rear end of the housing 1. A connecting block 308 is provided at the outer end of the control module 301. Multiple groups of heat pipes 309 are provided inside the connecting block 308. Both ends of the heat pipes 309 are provided with docking frames 303. Fins 305 are provided inside the docking frames 303. By using a heat pipe 309 to connect two groups of fins 305, the heat dissipation area is increased to assist heat dissipation, so that more heat can come into contact with the air and dissipate into the environment, avoiding excessively high temperature that affects its brightness and color, and ensuring the stable operation of the projector.

[0027] See also Figure 2-Figure 4In this embodiment, a fan 302 is provided on the inner wall of the docking frame 303. An output plate 304 is provided on the side of the fan 302 away from the fins 305. A heat conducting plate 307 is provided on the outer side of the output plate 304. A transmission tube 306 is provided between the output plate 304 and the heat conducting plate 307. By using the fan 302 in combination with the output plate 304 to connect to the heat conducting plate, heat is dissipated from the heat-generating components inside the projector, accelerating air flow and taking away the heat generated inside the projector. The heat conducting plate can quickly transfer the heat from the heat-generating components to other areas, making the heat distribution more uniform and assisting the fan 302 in dissipating the heat into the air. To ensure that the internal heating parts can be maintained at a low operating temperature and improve the heat dissipation efficiency of the projector, a temperature sensor 310 is provided at the lower end of the control module 301, and the temperature sensor 310 is electrically connected to the control module 301 and the fan 302. By using the temperature sensor 310 to monitor the internal temperature, the control module 301 is driven to adjust the fan 302 for heat dissipation according to the actual temperature conditions, thereby increasing the air flow and avoiding damage to the projector caused by temperature fluctuations. When the temperature drops to a certain level, the control module 301 will reduce the speed of the fan 302 to avoid unnecessary energy waste.

[0028] When working, first select a suitable LED light source 202 according to the user's usage requirements, and thread the selected LED light source 202 through the positioning frame 201 and the threaded ring 206 to ensure that the LED light source 202 is accurately aligned with the optical system of the projector. Using the LED light source 202 for projection reduces the frequency and cost of replacing bulbs. At the same time, the LED light source has a slower attenuation rate and lower power consumption, which saves a lot of energy. The LED light source does not generate a lot of heat during the light-emitting process, which reduces the heat generation of the projector, avoids overheating and short-circuit damage of the projector, and maintains stable operation of the projector. During the use of the projector, start the drive module 204 to connect the gear 205 to drive the rack 203 to adjust the rotation of the light source 202LED, optimize the distribution of light in the projection lens, make the projection picture clearer, the color more accurate, and improve the projection effect.

[0029] Secondly, when the projector is running, a temperature sensor 310 is used to monitor the internal temperature, and the control module 301 is driven to adjust the fan 302 to dissipate heat according to the actual temperature conditions, thereby increasing the air flow and avoiding damage to the projector caused by temperature fluctuations. When the temperature drops to a certain level, the control module 301 will reduce the speed of the fan 302 to avoid unnecessary energy waste. When the fan 302 is running, the heat pipe 309 connects the two sets of fins 305 to increase the heat dissipation area to assist in heat dissipation, accelerate air flow, and allow more heat to come into contact with the air and dissipate into the environment. The heat conduction plate can quickly transfer the heat from the heating parts to other areas, ensuring that the internal heating parts can maintain a low operating temperature and ensure the stable operation of the projector.

[0030] Through the above steps, by using the LED light source 202 for projection, the frequency and cost of replacing the bulb are reduced. At the same time, the LED light source has a slower attenuation rate and lower power consumption, which saves a lot of energy. The LED light source does not generate a lot of heat during the light-emitting process, which reduces the heat generation of the projector, avoids overheating and short circuit damage of the projector, and maintains stable operation of the projector. Secondly, the temperature sensor 310 is used to monitor the internal temperature, and the control module 301 is driven according to the actual temperature conditions to adjust the fan 302 for heat dissipation, increase the air flow, and avoid damage to the projector due to temperature fluctuations. When the temperature drops to a certain level, the control module 301 will reduce the speed of the fan 302 to avoid unnecessary energy waste.
