Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of projecting lamp, especially to a LED projecting lamp with heat dissipation function. BACKGROUND

[0002] LED (Light Emitting Diode) is a kind of semiconductor device, and a large amount of heat will be generated when it works. Compared with traditional incandescent lamps and fluorescent lamps, LED lamps have higher light efficiency and higher energy conversion efficiency, but the high power density also makes the heat generated by LED lamp body relatively more. Excessive working temperature not only affects the light decay (light efficiency decline) and color temperature change of LED, but also may cause the light source and driving circuit inside the LED lamp body to age prematurely, and even cause failure due to high temperature, thereby shortening the service life of LED lamp. With the continuous development of LED technology, LED lamps have been widely used in various lighting scenes such as outdoor projection, building lighting, street lighting, etc. due to their energy saving, environmental protection and long service life. Especially in the application of high-power LED projecting lamp, because it needs to bear a large power and emit a high luminous flux, the heat dissipation problem becomes a key factor limiting its performance and service life.

In this way, the heat dissipation efficiency of the radiator is significantly improved, because the accumulation of dust will seriously affect the performance of the radiator. The introduction of these structures not only improves the cleaning convenience of the radiator, but also ensures that each part of the radiator can be effectively moved, supported and fixed, thereby greatly improving the heat dissipation effect.

[0004] However, although the heat dissipation structure has been set in prior art 1, its heat dissipation structure is relatively simple, which limits its heat dissipation capacity to some extent. Especially in the use process of LED projecting lamp, because of its high brightness and large power, the heat dissipation is also relatively high. The generation of such high heat puts higher requirements on the heat dissipation of LED lamp.

[0030] Example 1

[0031] Please see Figure 1 The utility model embodiment provides a structure for LED projection lamp carries out heat dissipation and its LED lamp body 200 is transparent to the lamp body part of projection lamp, the heat dissipation mechanism 300 is used to carry out heat dissipation to the lamp body. The working temperature of LED lamp body 200 is one of the main factors of influencing its performance. The temperature of the inside of LED lamp body 200 increases when working and will cause the temperature of LED chip to increase, and the light efficiency reduces, thereby making the light brightness of its emission gradually decline, and even the color temperature deviation phenomenon appears. And in use, the temperature of LED lamp body 200 is too high and will also accelerate the aging of LED light source, causes its service life to shorten greatly, and even can cause the damage of LED chip. If this temperature cannot be discharged for a long time, also will produce the fire and other security risks, especially in the environment is relatively closed or ventilation is poor, the problem of heat accumulation will be enlarged.

[0032] Therefore, in the embodiment, provide a kind of LED projection lamp with heat dissipation function, to carry out effective heat dissipation to LED lamp body 200, ensure that it can normally work in stable temperature range, to prolong lamp life, improve safety and keep illumination effect.

[0033] Please see Figure 1 And Figure 2 In the embodiment, a kind of LED projection lamp with heat dissipation function is by including lamp cylinder 100, LED lamp body 200 and heat dissipation mechanism 300 three major parts;The lamp cylinder 100 is the shell structure of entire projection lamp, it not only plays the role of protection internal component, simultaneously provides the space for the installation of LED lamp body 200 and heat dissipation mechanism 300;The LED lamp body 200 is set in lamp cylinder 100 interior, is the core part of projection lamp, for light emission, illumination;And the heat dissipation mechanism 300 is similarly set in the interior of the lamp cylinder 100, with the LED lamp body 200 cooperation work, its main function is to effectively conduct and dissipate the heat generated by LED lamp body 200 in working process, to ensure that LED lamp body 200 is in a normal working temperature in lamp cylinder 100, prolongs service life.

[0034] In the embodiment, by this design, the LED projection lamp can not only provide stable illumination effect, but also effectively avoid the performance decline or damage caused by overheating, to improve the reliability and safety of product.

[0035] Please see Figure 2In the embodiment, the heat dissipation mechanism 300 is tightly fitted with the LED lamp body 200 through a contact type connection, which mainly provides effective heat dissipation for the LED lamp body 200. When the LED lamp body 200 is performing the lighting task, a large amount of heat will be generated over time, especially when the brightness and power of the LED lamp body 200 are high, which will make the heating phenomenon more significant. Therefore, by combining the heat dissipation mechanism 300 with the LED lamp body 200 through a contact type installation method, it can ensure that the heat generated by the LED lamp body 200 can be quickly conducted out of the surface of the LED lamp body 200 after the heat is generated, so as to maintain the LED lamp body 200 within a suitable operating temperature range and ensure its normal and stable operation.

[0036] Further, referring to Figure 2 , the design of the heat dissipation mechanism 300 includes at least two heat sinks, specifically, a first heat sink 310 and a second heat sink 320. The two heat sinks each adopt a different heat dissipation method to work together to effectively dissipate the heat generated by the LED lamp body 200 during operation. The first heat sink 310 can adopt a heat conduction method to guide the heat into the first heat sink 310, while the second heat sink 320 dissipates the heat on the first heat sink 310 to the outside of the lamp barrel 100. Through this combination, the heat dissipation mechanism 300 can more comprehensively cope with the heat dissipation needs of the LED lamp body 200 under different working conditions, ensuring the stable operation of the LED lamp and prolonging its service life.

[0037] In the embodiment, the first heat sink 310 is arranged at a specific position between the LED lamp body 200 and the second heat sink 320; this layout ensures that the heat sinks can work effectively together to achieve the best heat dissipation effect. The first heat sink 310 is provided with a plurality of evenly distributed fixing grooves 315 on the machine body, which are arranged to ensure that the second heat sink 320 can be stably installed on the first heat sink 310; the second heat sink 320 is fixed by arranging a rack 321 and hanging one end of the rack 321 on the fixing groove 315 of the first heat sink 310, so that the position of the second heat sink 320 is fixed. In this way, the first heat sink 310 and the second heat sink 320 together form a whole heat dissipation system.

[0038] Referring to Figure 2In the process of dissipating heat of the LED lamp body 200, the heat generated by the LED lamp body 200 is first transferred to the first heat sink 310 in a heat conduction manner, and the heat on the first heat sink 310 is effectively discharged to the outside of the lamp barrel 100 through the second heat sink 320 or heat exchange with external air, thereby avoiding the accumulation of heat inside the lamp barrel 100, ensuring the normal working temperature of the LED lamp body 200, and prolonging the service life of the LED lamp.

[0039] Further, please refer to Figure 1 , the bottom of the lamp barrel 100 is provided with a plurality of air outlets 120 to effectively discharge the heat inside the lamp barrel 100 through the second heat sink 320; the LED lamp body 200 is installed in contact with the first heat sink 310, so that the heat generated by the LED lamp body 200 is effectively and quickly transferred to the first heat sink 310, and finally discharged through the second heat sink 320 and the air outlet 120, thereby ensuring the high efficiency of the LED lamp.

[0040] Please refer to Figure 2 and Figure 3 In this embodiment, the LED lamp body 200 includes a lamp head 210 and a base 220 arranged at the bottom of the lamp head 210. The base 220 is arranged as a brass base 220, which serves to improve the heat dissipation efficiency of the LED lamp body 200 and increase the stability of the LED lamp body 200. Brass has good heat conduction performance and can quickly conduct the heat generated by the LED lamp body 200 to the first heat sink 310, further improving the heat dissipation effect. At the same time, the firmness of the brass base 220 also ensures the stable installation of the LED lamp body 200, avoiding damage to the lamp caused by vibration or external force. Through this design, the LED projector lamp not only has excellent heat dissipation performance, but also ensures the stability and durability of the lamp, providing users with a more reliable and safe lighting solution.

[0041] Please refer to Figure 3 , the base 220 is also provided with a heat-conducting mounting plate 230; the two ends of the base 220 are in contact with the heat-conducting mounting plate 230 and the lamp head 210 respectively, and the heat-conducting mounting plate 230 serves to further conduct the heat generated by the LED lamp body 200 during work to the heat dissipation mechanism 300, and to install and fix part of the LED lamp body 200.

[0042] The heat-conducting mounting plate 230 is made of high-thermal-conductivity materials, such as aluminum alloy or copper alloy, which can efficiently transfer heat, ensuring that heat is rapidly transferred from the LED lamp body 200 to the heat-dissipating mechanism 300. In this way, the heat-conducting mounting plate 230 not only enhances the heat transfer efficiency between the LED lamp body 200 and the heat-dissipating mechanism 300, but also helps maintain the LED lamp body 200 within a stable temperature range, preventing performance degradation or damage caused by overheating. The heat-conducting mounting plate 230 is mainly designed for convenience and stability of installation, ensuring that the LED lamp body 200 can be securely mounted on the heat-dissipating mechanism 300, avoiding loosening or damage of the lamp due to vibration or external force.

[0043] Please refer to Figure 3 The heat-conducting mounting plate 230 is uniformly and evenly spaced with several mounting legs 231, and the inside of the lamp barrel 100 is provided with several support blocks 110 adapted to the heat-conducting mounting plate 230; the LED lamp body 200 is fixed in the lamp barrel 100 by the mounting legs 231 and the support blocks 110. The mounting legs 231 enable the heat-conducting mounting plate 230 to form good contact and support with the support blocks 110 inside the lamp barrel 100, ensuring that the LED lamp body 200 can remain horizontal and stable during installation, avoiding deformation or loosening caused by improper installation or long-term use; the cooperation of the mounting legs 231 and the support blocks 110 can also disperse the heat generated by the LED lamp body 200 to some extent, so that the heat can be exchanged and dissipated from the lamp barrel 100, further improving the heat-dissipating effect and ensuring that the LED projector can work continuously and stably.

[0044] Please refer to Figure 3 In this embodiment, the central area of the heat-conducting mounting plate 230 is provided with a heat-dissipating hole 232, which is designed to improve the heat-dissipating efficiency of the entire system. In addition, the first heat-dissipating device 310 is designed to contain several groups of heat-conducting pieces 311, which are arranged at uniform angles, ensuring that heat can be uniformly transferred from the heat source to the heat-dissipating device. These heat-conducting pieces 311 are made into a thin sheet structure, which not only reduces the weight of the heat-dissipating device, but also makes heat conduction more efficient due to the large surface area of the sheet structure. The central part of the first heat-dissipating device 310 is also specially designed with air flow channels 314 communicating with the heat-dissipating hole 232, which allows hot air to flow directly to the second heat-dissipating device 320 through these flow channels. In this way, the heat generated by the brass base 220 can be effectively transferred through the heat-dissipating hole 232 and discharged by the second heat-dissipating device 320 through the air flow channels 314. This design makes the heat transfer no longer limited to a single heat-conducting mounting plate 230, but can be transferred through multiple angles and paths, thereby further improving the overall performance of the heat-dissipating system.

[0045] Please refer to Figure 4 and Figure 5 Each of the heat-conducting members 311 includes a first heat dissipation fin 312 and a second heat dissipation fin 313, and a gap is provided between the first heat dissipation fin 312 and the second heat dissipation fin 313. This arrangement can not only keep the air flowing between the heat dissipation fins and improve the heat dissipation efficiency, but also avoid the poor heat conduction caused by the direct contact between the heat dissipation fins. The fins are more easily exchanged with the external air. The gap between the first heat dissipation fin 312 and the second heat dissipation fin 313 allows the air to flow freely between the fins, increasing the heat exchange area and thus improving the heat dissipation effect. At the same time, the sheet structure of the heat dissipation fins also increases the heat dissipation area, further improving the heat dissipation efficiency. Through this design, the heat dissipation mechanism 300 can more effectively conduct the heat generated by the LED lamp body 200 out and transfer it to the second heat sink 320 through the air flow channel 314, and finally discharge it to the outside of the lamp barrel 100, ensuring that the LED lamp body 200 works within a stable temperature range and prolongs its service life.

[0046] Please refer to Figure 4 The gap provided between the first heat dissipation fin 312 and the second heat dissipation fin 313 is smaller than the gap provided between adjacent heat-conducting members 311. This can make the air flow through the first heat dissipation fin 312 and the second heat dissipation fin 313 receive more resistance, thereby increasing the residence time of the air between the fins and improving the heat exchange efficiency. At the same time, this design also makes the air flow between adjacent heat-conducting members 311 more smooth, avoiding the air flow obstruction caused by the too small gap between the heat-conducting members 311, and further improving the heat dissipation effect. In this embodiment, the heat dissipation mechanism 300 can achieve efficient conduction and dissipation of the heat generated by the LED lamp body 200, ensuring that the LED lamp body 200 works within a stable temperature range and prolonging its service life and improving the lighting effect.

[0047] Please refer to Figure 4 In order to enable the second heat sink 320 to be assembled with the first heat sink 310, the fixing groove 315 is provided on the heat-conducting member 311, and the fixing groove 315 is provided through at least four heat-conducting members 311 to ensure that the second heat sink 320 can be stably installed on the first heat sink 310, improving the stability and heat dissipation effect of the heat dissipation mechanism 300. Through the fixing groove 315 on at least four heat-conducting members 311, the second heat sink 320 can be stably connected with the first heat sink 310. At the same time, the provision of the fixing groove 315 can also enhance the connection strength between the first heat sink 310 and the second heat sink 320, avoiding loosening or falling off caused by vibration or external force during work, and further ensuring the stability and safety of the LED projector.

[0048] Please refer to Figure 6 The second heat sink 320 further comprises a heat dissipation fan 322 arranged in the frame 321, which is mounted on the frame 321 and rotates based on the frame 321. The heat dissipation fan 322 is arranged as a negative pressure fan, which can discharge the heat on the first heat sink 310 to the outside of the lamp barrel 100.

[0049] Further, the rotating speed of the heat dissipation fan 322 can be intelligently adjusted according to the working state of the LED lamp body 200. When the LED lamp body 200 works in a high brightness and high power state, the rotating speed of the heat dissipation fan 322 will automatically increase to cope with greater heat dissipation demand; and when the LED lamp body 200 works in a lower brightness or standby state, the rotating speed of the heat dissipation fan 322 will be reduced accordingly to reduce energy consumption and noise. This intelligent adjustment function not only improves the heat dissipation efficiency, but also makes the entire LED light projector system more energy-saving and environmentally friendly.

[0050] Please refer to Figure 6 The frame 321 is provided with a plurality of hanging ears 323 at one end close to the first heat sink 310, which are connected with the fixing groove 315 by hanging and buckling. The frame 321 is hollow arranged for discharging heat; and the frame 321 is further provided with a mounting bracket 324 at the other end away from the first heat sink 310 for mounting the heat dissipation fan 322. In this way, the stable mounting of the heat dissipation fan 322 can be ensured, and the heat dissipation fan 322 can fully inhale the surrounding air and discharge the heat from the inside of the lamp barrel 100 when working. At the same time, the hollow frame 321 design can also reduce the weight of the entire heat dissipation mechanism 300 and improve the heat dissipation efficiency. Through this design, the heat dissipation mechanism 300 can more effectively discharge the heat generated by the LED lamp body 200 to the outside of the lamp barrel 100, ensuring that the LED lamp body 200 works in a stable temperature range, thereby prolonging its service life and improving the lighting effect and safety.

[0051] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
