DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The present invention provides a lamp with good heat dissipation effect, comprising a base 1 and a lamp body 2, wherein the lamp body 2 is preferably rotatably arranged on the base 1, wherein a light source 35 and a light source heat dissipation structure are arranged inside the lamp body 2, the light source heat dissipation structure comprises a hollow copper tube 31, an exhaust fan 32, an exhaust fan 33 and a first heat dissipation fan 34, the exhaust fan 32 and the exhaust fan 33 are distributed on the left and right sides of the light source 35, the hollow copper tube 31 comprises a main tube 36, a first extension tube 37 and a second extension tube 38, one end of the first extension tube 37 is connected to one end of the main tube 36, one end of the second extension tube 38 is connected to the other end of the main tube 36, the exhaust fan 32 is arranged correspondingly to the other end of the first extension tube 37, the exhaust fan 33 is arranged correspondingly to the other end of the second extension tube 38, the first heat dissipation fan 34 is arranged correspondingly to the main tube 36, and a through hole is provided at a position of the lamp body 2 close to the first heat dissipation fan 34 so that the first heat dissipation fan 34 is connected to the outside.

[0028] It can be understood that the heat dissipation principle of the light source heat dissipation structure of the present invention is: when working, the light source 35 will generate more heat; first, the heat emitted by the light source 35 is drawn into the main tube 36 of the hollow copper tube 31 through the other end of the first extension tube 37 by the exhaust fan 32; further, the first cooling fan 34 blows the outside cold air to the main tube 36 to dissipate the heat and cool down the hot air containing the heat of the light source in the main tube 36 to form cold air; finally, the cold air in the main tube 36 is discharged from the hollow copper tube 31 through the other end of the second extension tube 38 by the exhaust fan 33; in the above manner, an air-cooled heat dissipation circulation system is formed at the internal light source of the lamp to achieve a better heat dissipation effect on the light source 35.

[0029] Preferably, the light source heat dissipation structure of the present invention may further include a second heat dissipation fan 311 and a third heat dissipation fan 312. The second heat dissipation fan 311 and the third heat dissipation fan 312 are respectively arranged on the front side and the rear side of the light source 35. The second heat dissipation fan 311 and the third heat dissipation fan 312 are used to blow air to dissipate the light source 35 to further improve the heat dissipation effect of the light source heat dissipation structure.

[0030] In addition, preferably, the light source heat dissipation structure of the present invention also includes a first blower 313, and the first blower 313 is arranged above the exhaust fan 33, and the air outlet of the first blower 313 is toward the light source 35. The cold air exhausted by the exhaust fan 33 is blown toward the light source 35 by the first blower 313 to better ensure the heat dissipation effect of the light source 35.

[0031] The present invention may further include a second blower, which is arranged inside the lamp body 2 and close to the top of the lamp body 2, the light source 35 and the light source heat dissipation structure are close to the bottom of the lamp body 2, and the air outlet of the second blower is downward. The second blower blows air downward so that the light source heat dissipation structure can better perform the heat dissipation cycle of hot air and cold air to ensure the heat dissipation effect, and makes the temperature inside the lamp body 2 more uniform, thereby better ensuring the service life of the lamp.

[0032] In addition, specifically, the light source heat dissipation structure may also include a mounting plate 39, the exhaust fan 32 and the exhaust fan 33 are arranged on the left and right sides of the top surface of the mounting plate 39, the light source 35 is located between the exhaust fan 32 and the exhaust fan 33 and is located above the top surface of the mounting plate 39, and the hollow copper tube 31 is arranged on the bottom surface of the mounting plate 39.

[0033] Preferably, the light source heat dissipation structure further includes a heat sink 310, which is disposed on the bottom surface of the mounting plate 39. The heat sink 310 is provided with a receiving groove for receiving the main body tube 36. The heat sink 310 is provided to further improve the heat dissipation effect of the light source heat dissipation structure. The number of heat sinks 310 is preferably multiple, and the multiple heat sinks 310 are spaced apart along the length direction of the main body tube 36. The lamp of the present invention can be applied to different places such as stages, hotels, and stadiums, and no excessive restrictions are made here.

[0034] Specifically, there are two exhaust fans 32 and two exhaust fans 33. In addition, two first cooling fans 34 are disposed on the front and rear sides of the mounting plate 39, and the hollow copper tube 31 is located between the first cooling fans 34 on the front and rear sides.

[0035] Preferably, there are multiple hollow copper tubes 31, and the multiple hollow copper tubes 31 are arranged at intervals. Further, the lengths of different hollow copper tubes 31 can be the same or different, and there is no excessive restriction here.

[0036] In addition, preferably, the present invention may further include a rotation driving device, which is connected to the light source 35. The rotation driving device drives the light source 35 to rotate, which can avoid the cold air discharged by the exhaust fan 33, the second cooling fan 311, and the third cooling fan 312 from blowing air to the light source 35 at a fixed point, so that the light source 35 can be evenly cooled, and the service life of the light source 35 can be better guaranteed. The above-mentioned rotation driving device can specifically adopt a motor or other devices, which is not too limited here.

[0037] Preferably, the present invention may further include a controller and a photosensitive module, wherein the controller is connected to the light source and the photosensitive module, wherein the photosensitive module is disposed on the outer wall of the lamp body 2, and the controller is disposed inside the lamp body 2. The light intensity of the current environment of the lamp is monitored by the photosensitive module and further transmitted to the controller. The controller calculates the target color temperature by the following formula (1) and controls the color temperature of the light source 35 accordingly:

[0038] CT=2700+15×(Lux-100) (1)

[0039] Wherein, CT represents the target color temperature (unit: Kelvin / Kelvin), Lux represents the light intensity (unit: lux / Lux); the above formula (1) represents the following reference value setting: when the light intensity is 100Lux, the color temperature of the light source is set to 2700K (warm white, similar to dusk light); the above formula (1) represents the following linear relationship: for every increase of 100Lux light intensity, the color temperature increases by 1500K (for example: under 500Lux ambient light, CT=2700+15×400=8700K, cold white). Through the above-mentioned manner, the present invention can dynamically adjust the color temperature of the light source of the lamp according to the light intensity, bringing the following technical effects: first, realizing automatic fill light balance: when the light in the current environment (such as the stage) of the lamp is strong, the light source of the lamp automatically switches to high color temperature cold light to avoid the warm light being submerged by the ambient light; second, realizing situational rendering: for example, the lamp of the present invention is applied to the main stage of a concert. At the climax of the concert, the ambient light may become messy due to the flash of the audience's mobile phones. The lamp of the present invention enhances the contrast of the light source by increasing the color temperature (colder) to highlight the focus of the main stage; third, improving the user experience and perception: the present invention can dynamically adjust the color temperature according to the changes in the ambient light, such as using cold light with a higher color temperature when the natural light is strong during the day, and using warm light at night or in dim environments. This can reduce eye fatigue and improve the viewing experience.

[0040] In addition, the light source of the present invention can specifically adopt the existing technology to realize a gradient light source that gradually changes the light brightness or light color at a certain gradient speed; further preferably, the present invention can also include a carbon dioxide detector, which is arranged on the outer wall of the above-mentioned lamp body 2, and the carbon dioxide detector is connected to the controller, and the carbon dioxide concentration of the current environment of the lamp is detected by the carbon dioxide detector. Further, the controller calculates the light gradient speed through the following formula (2) and controls the light brightness gradient speed or light color gradient speed of the light source 35 accordingly:

[0041] Speed ​​= 0.1 × CO2_ppm (2)

[0042] Wherein, Speed ​​represents the light gradient speed (unit: custom rate unit, for example, times / 150 seconds), CO2_ppm represents the carbon dioxide concentration (unit: ppm); the above formula (2) indicates that for every 100 ppm increase in carbon dioxide concentration, the light gradient speed increases by 10 units accordingly, for example: the lamp of the present invention is used in a quiet theater (CO2_ppm=300) → Speed=30 (slower gradient); the lamp of the present invention is used after an intense dance performance (CO2_ppm=2000) → Speed=200 (fast flashing / flowing effect). Through the above-mentioned method, the present invention can dynamically adjust the gradient speed of the light source according to the carbon dioxide concentration of the environment in which the lamp is located: on the one hand, it can realize environmental health warning: when the CO2 concentration of the environment in which the lamp of the present invention is located exceeds the standard (such as >1500ppm), the light gradient speed of the corresponding light source is controlled to be faster, so as to remind the staff to ventilate the on-site environment through the rapid flashing of the light; on the other hand, it can realize dynamic atmosphere matching: when the lamp of the present invention is used in a highly interactive performance scene, the audience's breathing and movements cause the CO2 concentration of the current environment to fluctuate, and the light gradient speed changes accordingly, thereby better enhancing the real-time and sense of immersion of the performance.

[0043] Compared with the prior art, the present invention provides a lamp with good heat dissipation effect, which has the following beneficial effects: (1) The light source heat dissipation structure of the present invention includes a hollow copper tube, an exhaust fan, an exhaust fan and a first heat dissipation fan. First, the heat emitted by the light source is drawn into the hollow copper tube by the exhaust fan, and further, the hot air containing the heat of the light source in the hollow copper tube is blown by the first heat dissipation fan to dissipate heat and cool down to form cold air. Finally, the cold air in the hollow copper tube is discharged by the exhaust fan. In the above manner, an air-cooled heat dissipation circulation system is formed at the internal light source of the lamp, which can better ensure the heat dissipation effect of the light source and better ensure the service life of the lamp. (2) The prior art usually adopts the arrangement of heat dissipation fins on the top surface of the mounting plate to conduct the heat of the light source, and the heat dissipation fins will occupy a large space. The present invention only needs to arrange the exhaust fan and the exhaust fan on the top surface of the mounting plate, which will reduce the occupied space compared with the prior art. (3) The light source heat dissipation structure of the present invention has high integration, which can facilitate the overall installation and disassembly of the light source heat dissipation structure, thereby facilitating the maintenance of the light source and other lamp components. (4) When the prior art uses copper tubes for heat dissipation, coolant is usually injected into the copper tube, and the openings at both ends of the copper tube are further closed. The heat of the light source is absorbed by the coolant in the copper tube. However, the coolant is prone to failure after long-term use, which leads to failure of the heat dissipation function of the copper tube, and the replacement of the copper tube is troublesome. The light source heat dissipation structure of the present invention adopts a hollow copper tube, which means that there is no need to inject coolant into the copper tube, and an air-cooled heat dissipation cycle is used to dissipate the heat of the light source. The hollow copper tube of the present invention is not prone to failure, and the exhaust fan, exhaust fan, and first heat dissipation fan located outside the hollow copper tube are relatively easy to disassemble and replace. (5) By providing a first blower and a second blower, the heat dissipation effect of the present invention can be better guaranteed. (6) By driving the light source to rotate by a rotary drive device, it is possible to avoid the light source heat dissipation structure from blowing air to a fixed point on the light source, so that the light source can be evenly dissipated and the service life of the light source can be better guaranteed.
