[0002] During the operation of the light source of a lamp, especially a stage lamp, a large amount of heat is often generated. At present, an aluminum profile radiator is often used in cooperation with a fan to dissipate heat from the light source. On the one hand, due to the principle that hot air moves upward, a large temperature difference is caused between the upper and lower parts, which further affects the heat dissipation effect of the light source located above.

In the description of the present utility model, unless otherwise stated, the meaning of "a plurality of" is two or more. In addition, the terms "first" and "second" are only used for descriptive distinction and have no special meaning. Among them, the terms "first position" and "second position" are two different positions.

[0046] The technical solution of the present utility model will be further described below with reference to the drawings and through specific embodiments.

[0047] As Figures 1 to 7 shown, an embodiment of the present application provides a heat dissipation structure applied to a lamp, and the heat dissipation structure includes a housing 110, a heat transfer member, a heat dissipation member 130 and a fan 140.

[0048] The housing 110 defines a receiving cavity 111, and the receiving cavity 111 has an air outlet 112 communicating with the outside, which helps air circulation and realizes heat dissipation inside the receiving cavity 111. It should be noted that the sizes and formations of the receiving cavity 111 and the air outlet 112 can be designed according to actual needs, and the present embodiment does not make specific limitations thereto.

[0049] A plurality of heat transfer members spaced apart from each other are disposed in the accommodation cavity 111. The heat transfer member includes a first section 1201 and a second section 1202. The first section 1201 extends in the up and down direction and is used for abutting against the light source member 200 of the lamp. One end of the second section 1202 is disposed on the first section 1201 and extends in a direction away from the light source member 200, and the projection of the second section 1202 on the light source member 200 is located in the middle of the light source member 200 in the up and down direction. It should be noted that the shape, size and number of the heat transfer members can be adjusted according to actual needs, and the present embodiment does not make specific limitations thereon.

[0050] It can be understood that considering that a large amount of heat is generated when the light source member 200 operates, by arranging a plurality of heat transfer members spaced apart from each other and making the first section 1201 of the heat transfer member extending in the up and down direction fit the surface of the light source member 200, it helps to quickly transfer heat. In addition, since the second section 1202 extends in a direction away from the light source member 200 and its projection is located in the middle of the light source member 200, the heat from various parts of the light source member 200 is transferred through the first section 1201 and concentrated on the second section 1202, which helps to more evenly distribute the heat, and as much as possible reduces the temperature difference between the upper and lower parts of the accommodation cavity 111, ensuring that the heat can be evenly distributed over the entire light source member 200.

[0051] A plurality of heat dissipation members 130 connected in sequence along a first direction. The heat dissipation members 130 are disposed in the accommodation cavity 111, and the second section 1202 is disposed between two adjacent heat dissipation members 130. It should be noted that the number and size of the heat dissipation members 130 can be designed according to actual needs, and the present embodiment does not make specific limitations thereon.

[0052] For the convenience of subsequent description, the width direction of the heat dissipation member 130 is the first direction; the length direction of the heat dissipation member 130 is the second direction, and the extending direction of the second section 1202 is parallel to the second direction; the height direction of the heat dissipation member 130 is the up and down direction.

[0053] It should be noted that the light source member 200, the first section 1201 and the heat dissipation members 130 are distributed in sequence along the second direction. Since the first section 1201 of the heat transfer member extends in the up and down direction and is attached to the surface of the light source member 200, and the second section 1202 of the heat transfer member is attached to the heat dissipation member 130 and one end of the second section 1202 is connected to the first section 1201, that is, the heat from various parts of the surface of the light source member 200 is first absorbed by the first section 1201 of each heat transfer member, and then the second section 1202 transfers the heat absorbed by the first section 1201 to the heat dissipation member 130, and the heat is dissipated through the heat dissipation member 130.

[0054] It can be understood that, compared with the related art where the heat dissipation component directly dissipates heat from the light source component, the heat below will move upward and converge with the heat above the light source component, resulting in the temperature above the light source component near the light source component in the accommodation cavity being much higher than the temperature below, that is, the temperature difference between the upper and lower parts near the light source component in the accommodation cavity is relatively large, affecting the heat dissipation effect of the upper part of the light source component. By extending the first section 1201 in the vertical direction and the second section 1202 in the direction away from the light source component 200 and its projection being located in the middle of the light source component 200, the heat absorbed by the heat transfer component from both the upper and lower parts near the light source component 200 in the accommodation cavity 111 is concentrated in the middle of the accommodation cavity 111 near the light source component 200 for overall heat dissipation. The heat in the upper part of the light source component 200 can be guided by the heat transfer component to move downward to the middle first, thereby reducing the temperature difference between the upper and lower parts of the light source component 200 and ensuring the overall heat dissipation effect of the light source component 200.

[0055] In addition, compared with the related art where the light source component is in direct contact with the heat dissipation component and used in conjunction with a fan, since the thermal conductivity of the heat transfer component is much higher than the thermal conductivity of the heat dissipation component 130 itself, the heat dissipation efficiency can be improved, the service life of the lamp can be extended, the amount of air volume required for heat dissipation in the accommodation cavity 111 can be reduced, and the noise can be reduced to ensure the normal use of the lamp.

[0056] According to the heat dissipation structure provided by the embodiment of the present application, by arranging the heat transfer component to be in contact with the light source component 200 and the heat dissipation component 130 respectively, and the first section 1201 of the heat transfer component extends in the vertical direction, the second section 1202 extends in the direction away from the light source component 200, and the projection of the second section 1202 on the light source component 200 is located in the middle of the light source component 200 in the vertical direction, it is helpful to quickly transfer heat while uniformly dissipating heat from the light source component 200, reduce noise, and extend the service life of the lamp.

[0057] In some embodiments, as Figures 2 to 7 shown, the heat transfer component is in an L - shaped form, that is, one end of the second section 1202 is connected to one end of the first section 1201; of course, in other embodiments, the heat transfer component can also be in a T - shaped form, that is, one end of the second section 1202 is connected to the middle of the first section 1201 in the vertical direction, and this embodiment does not make specific limitations on this.

[0058] In some embodiments, as Figures 2 to 7 shown, the cross - sections of the first section 1201 and the second section 1202 are both square, ensuring that the contact surface between the first section 1201 and the light source component 200 and the contact surface between the second section 1202 and the heat dissipation component 130 are flat, so as to maximize the contact area and reduce the air gap, which is helpful to improve the heat conduction efficiency. Of course, in other embodiments, the cross - sections of the first section 1201 and the second section 1202 can also be circular, elliptical, etc., and this embodiment does not make specific limitations on this.

[0059] In some embodiments, as Figures 3 to 7 shown, some of the plurality of heat transfer members are spaced apart in the first direction to form a first heat transfer portion for heat exchange with the upper part of the light source member 200; some of the plurality of heat transfer members are spaced apart in the first direction to form a second heat transfer portion for heat exchange with the lower part of the light source member 200, and the heat transfer members of the first heat transfer portion and the heat transfer members of the second heat transfer portion are in one-to-one correspondence.

[0060] For the convenience of subsequent description, the heat transfer members forming the first heat transfer portion are defined as the first heat transfer members 121, and the heat transfer members forming the second heat transfer portion are defined as the second heat transfer members 122, and the first heat transfer members 121 and the second heat transfer members 122 are in one-to-one correspondence.

[0061] It should be noted that the first section 1201 of the first heat transfer member 121 extends upward in a direction away from the second section 1202 of the first heat transfer member 121, the first section 1201 of the second heat transfer member 122 extends downward in a direction away from the second section 1202 of the second heat transfer member 122, and the second section 1202 of the first heat transfer member 121 is directly above the second section 1202 of the second heat transfer member 122.

[0062] It can be understood that the first heat transfer portion and the second heat transfer portion with one-to-one corresponding heat transfer members are formed by the regular arrangement of the heat transfer members, so as to ensure that the first sections 1201 of the corresponding heat transfer members are in contact with various places on the surface of the light source member 200 facing the heat sink 130, which helps to achieve a more uniform heat distribution, and can achieve more precise control of heat transfer according to the different heat generation and dissipation requirements that may exist in the upper and lower parts of the light source member 200, improve the heat dissipation efficiency, and minimize the hot spots generated due to heat concentration on the light source member 200, thereby extending the service life of the light source member 200 and improving the overall performance.

[0063] In some embodiments, as Figures 3 to 7 shown, in the up-down direction, the projection of the first section 1201 of the first heat transfer portion is symmetric with the projection of the corresponding first section 1201 of the second heat transfer portion along the extension direction of the second section 1202, and the projection of the second section 1202 of the first heat transfer portion coincides with the projection of the corresponding second section 1202 of the second heat transfer portion.

[0064] It can be understood that the projections of the first section 1201 of the first heat transfer member 121 and the corresponding first section 1201 of the second heat transfer member 122 are symmetric in the up-down direction along the second direction, that is, the projections of the first section 1201 of the first heat transfer member 121 and the first section 1201 of the second heat transfer member 122 are staggered in the up-down direction along the first direction, and the projections of the second section 1202 of the first heat transfer member 121 and the corresponding second section 1202 of the second heat transfer member 122 coincide in the up-down direction. Thus, the second section 1202 of the first heat transfer member 121 and the second section 1202 of the second heat transfer member 122 are provided between adjacent two heat dissipation members 130, which helps to improve the stability of the overall heat dissipation structure and the ability of uniform heat exchange.

[0065] In some embodiments, as Figures 3 to 7 shown, some of the multiple heat transfer members are spaced along the first direction to form a third heat transfer portion for heat exchange with the upper part of the light source member 200; some of the multiple heat transfer members are spaced along the first direction to form a fourth heat transfer portion for heat exchange with the lower part of the light source member 200. The heat transfer members of the third heat transfer portion and the heat transfer members of the fourth heat transfer portion are in one-to-one correspondence, and the second section 1202 of the third heat transfer portion and the second section 1202 of the fourth heat transfer portion are both located between the second section 1202 of the first heat transfer portion and the second section 1202 of the second heat transfer portion.

[0066] For the convenience of subsequent description, the heat transfer members forming the third heat transfer portion are defined as the third heat transfer members 123, and the heat transfer members forming the fourth heat transfer portion are defined as the fourth heat transfer members 124. The third heat transfer members 123 and the fourth heat transfer members 124 are in one-to-one correspondence.

[0067] It should be noted that the first section 1201 of the third heat transfer member 123 extends upward along the direction away from the second section 1202 of the third heat transfer member 123, and the first section 1201 of the fourth heat transfer member 124 extends downward along the direction away from the second section 1202 of the fourth heat transfer member 124. From top to bottom, the second section 1202 of the first heat transfer member 121, the second section 1202 of the fourth heat transfer member 124, the second section 1202 of the third heat transfer member 123, and the second section 1202 of the second heat transfer member 122 are arranged in sequence.

[0068] It can be understood that the third heat transfer portion and the fourth heat transfer portion with one-to-one corresponding heat transfer members are formed by the regular arrangement of the heat transfer members, so as to ensure that the first section 1201 of the corresponding heat transfer member contacts each place on the surface of the light source member 200 facing the heat dissipation member 130, which helps to further achieve a more uniform heat distribution, and can achieve a more precise control of heat transfer according to the different heat generation and dissipation requirements that may exist in the upper and lower parts of the light source member 200, improve the heat dissipation efficiency, and minimize the hot spots generated due to heat concentration on the light source member 200, thereby extending the service life of the light source member 200 and improving the overall performance.

[0069] In some embodiments, as Figures 3 to 7 shown, in the projection in the up-down direction, the projection of the first section 1201 of the third heat transfer section is symmetric with the projection of the corresponding first section 1201 of the fourth heat transfer section along the extending direction of the second section 1202, and the projection of the second section 1202 of the third heat transfer section coincides with the projection of the corresponding second section 1202 of the fourth heat transfer section.

[0070] It can be understood that the projection of the first section 1201 of the third heat transfer member 123 and the projection of the corresponding first section 1201 of the fourth heat transfer member 124 are symmetric in the up-down direction along the second direction, that is, the projection of the first section 1201 of the fourth heat transfer member 124 and the projection of the first section 1201 of the third heat transfer member 123 are staggered in the up-down direction along the first direction, and the projection of the second section 1202 of the third heat transfer member 123 coincides with the projection of the corresponding second section 1202 of the fourth heat transfer member 124 in the up-down direction, so that the second sections 1202 of the third heat transfer member 123 and the fourth heat transfer member 124 are arranged between two adjacent heat dissipation members 130, which helps to improve the stability of the overall heat dissipation structure and the ability of uniform heat exchange.

[0071] In some embodiments, as Figures 3 to 7 shown, in the up-down direction, the projection of the first section 1201 of the first heat transfer section coincides with the projection of the first section 1201 of the fourth heat transfer section, and the projection of the first section 1201 of the second heat transfer section coincides with the projection of the first section 1201 of the third heat transfer section.

[0072] It can be understood that the first heat transfer member 121, the second heat transfer member 122, the third heat transfer member 123 and the fourth heat transfer member 124 correspond to each other one by one, that is, the projection of the first section 1201 of the first heat transfer member 121 in the up-down direction coincides with the projection of the corresponding first section 1201 of the fourth heat transfer member 124 in the up-down direction, and the projection of the first section 1201 of the second heat transfer member 122 in the up-down direction coincides with the projection of the corresponding first section 1201 of the third heat transfer member 123 in the up-down direction, so as to ensure that the parts of the upper and lower parts of the light source member 200 in contact with the heat transfer members are symmetric in the up-down direction, ensuring uniform heat dissipation of the light source member 200. At the same time, since in the up-down direction, the projections of the second sections 1202 of the first heat transfer member 121, the corresponding second sections 1202 of the fourth heat transfer member 124, the corresponding second sections 1202 of the third heat transfer member 123 and the corresponding second sections 1202 of the second heat transfer member 122 coincide, the second sections 1202 of the first heat transfer member 121, the second heat transfer member 122, the third heat transfer member 123 and the fourth heat transfer member 124 are arranged between two adjacent heat dissipation members 130, which helps to further improve the stability of the overall heat dissipation structure and the ability of uniform heat exchange.

[0073] In some embodiments, as Figures 5 to 7 shown, some of the plurality of heat transfer members are arranged at intervals along the first direction to form a fifth heat transfer portion for heat exchange with the upper part of the light source member 200; some of the plurality of heat transfer members are arranged at intervals along the first direction to form a sixth heat transfer portion for heat exchange with the lower part of the light source member 200, and the projection of the fifth heat transfer portion in the up-down direction coincides with the projection of the sixth heat transfer portion in the up-down direction.

[0074] For the convenience of subsequent description, the heat transfer members forming the fifth heat transfer portion are defined as the fifth heat transfer members 125, the heat transfer members forming the sixth heat transfer portion are defined as the sixth heat transfer members 126, and the fifth heat transfer members 125 and the sixth heat transfer members 126 are in one-to-one correspondence.

[0075] It should be noted that the first section 1201 of the fifth heat transfer member 125 extends upward along the direction away from the second section 1202 of the fifth heat transfer member 125, and the first section 1201 of the sixth heat transfer member 126 extends downward along the direction away from the second section 1202 of the sixth heat transfer member 126. From top to bottom, the second sections 1202 of the first heat transfer member 121, the fifth heat transfer member 125, the fourth heat transfer member 124, the third heat transfer member 123, the sixth heat transfer member 126, and the second heat transfer member 122 are arranged in sequence.

[0076] It can be understood that the fifth heat transfer portion and the sixth heat transfer portion in one-to-one correspondence with the heat transfer members are formed by the regular arrangement of the heat transfer members, so as to ensure that the first sections 1201 of the corresponding heat transfer members are in contact with all parts of the surface of the light source member 200 facing the heat sink 130, which helps to further achieve a more uniform heat distribution, and can realize a more precise control of heat transfer according to the different heat generation and dissipation requirements that may exist in the upper and lower parts of the light source member 200, improve the heat dissipation efficiency, and minimize the hot spots generated on the light source member 200 due to heat concentration, thereby prolonging the service life of the light source member 200 and improving the overall performance.

[0077] In some embodiments, as Figures 5 to 7 shown, along the first direction, the first sections 1201 of the first heat transfer portion, the fifth heat transfer portion, and the third heat transfer portion are arranged in a cycle.

[0078] It can be understood that the first section 1201 of the first heat transfer element 121, the first section 1201 of the fifth heat transfer element 125 and the first section 1201 of the third heat transfer element 123 are arranged in a cycle along the first direction, and the first section 1201 of the fourth heat transfer element 124, the first section 1201 of the sixth heat transfer element 126 and the first section 1201 of the second heat transfer element 122 are arranged in a cycle along the first direction, which helps to achieve more uniform heat exchange, thereby reducing the concentration of heat in specific areas, avoiding the generation of hot spots as much as possible, improving the overall thermal stability, and also helping to ensure the balance of the entire heat dissipation structure.

[0079] In some embodiments, Figures 5 to 7 As shown, in the up-down direction, the projection of the second section 1202 of the fifth heat transfer portion coincides with the projection of the second section 1202 of the first heat transfer portion.

[0080] It can be understood that the first heat transfer element 121, the second heat transfer element 122, the third heat transfer element 123, the fourth heat transfer element 124, the fifth heat transfer element 125 and the sixth heat transfer element 126 correspond to each other one by one, so that in the up and down direction, the second section 1202 of the first heat transfer element 121, the second section 1202 of the fifth heat transfer element 125, the second section 1202 of the fourth heat transfer element 124, the second section 1202 of the third heat transfer element 123, the second section 1202 of the sixth heat transfer element 126 and the second heat transfer element 126 are connected to each other. The projections of the second sections 1202 of 22 overlap, so that the second sections 1202 of the first heat transfer member 121, the second sections 1202 of the fifth heat transfer member 125, the second sections 1202 of the fourth heat transfer member 124, the second sections 1202 of the third heat transfer member 123, the second sections 1202 of the sixth heat transfer member 126 and the second sections 1202 of the second heat transfer member 122 are provided between two adjacent heat transfer members 130, which helps to further improve the stability of the overall heat dissipation structure and the ability of uniform heat exchange.

[0081] In some embodiments, Figures 2 to 7 As shown, the heat sink 130 is made by continuous stamping, which has a simple and fast manufacturing process, and can greatly reduce the manufacturing process, shorten the working time and reduce the cost.

[0082] In some embodiments, Figure 7 As shown, both side walls of the heat dissipating element 130 that are arranged opposite to each other along the first direction are provided with through grooves 131 along the second direction, the outer side wall of the second section 1202 can be fitted with the inner side wall of the through grooves 131, and the through grooves 131 on the two adjacent sides of two adjacent heat dissipating elements 130 can be spliced ​​into a receiving groove for receiving the second section 1202. It should be noted that the number and shape of the through grooves 131 are designed according to the arrangement of the heat transfer element and the shape of the second section 1202, and this embodiment does not impose any specific restrictions on this.

[0083] In some embodiments, Figure 2, Figure 3 and Figure 5 As shown in Figure 3 and Figure 5 , the heat dissipation structure further includes a fan 140 and a partition 150. The partition 150 is installed on the bottom surface of the heat sink 130, and the fan 140 is installed on the side of the partition 150 away from the heat sink 130. The connection methods between the partition 150 and the heat sink 130 and between the fan 140 and the partition 150 include but are not limited to threaded connection or rivet connection, etc.

[0084] It can be understood that by setting the fan 140, it helps to promote the air flow speed inside and outside the accommodation cavity 111 through the air inlet 112, improving the heat dissipation effect. At the same time, based on the principle that hot air rises and cold air descends, setting the fan 140 below the heat sink 130 can enable the fan 140 to inhale relatively cold air and blow it upward to the heat sink 130, thereby helping to dissipate heat more effectively, reducing the accumulation of heat above the accommodation cavity 111, and avoiding the phenomenon of hot air flowing back to the upper part after accumulating below, ensuring the heat dissipation effect and efficiency.

[0085] In some embodiments, as Figure 2 , Figure 3 and Figure 5 shown, a plurality of fans 140 and partitions 150 are provided and correspond one by one. The plurality of fans 140 are spaced apart along the first direction to further improve the heat dissipation efficiency. It should be noted that the number of fans 140 can be designed according to actual needs, and this embodiment does not make specific limitations on this.

[0086] In some embodiments, as Figure 1 and Figure 2 shown, the outer wall surface of the housing 110 has a guiding inclined surface 113, and the air inlet 112 is located at the guiding inclined surface 113.

[0087] It can be understood that by providing the guiding inclined surface 113 on the outer wall surface of the housing 110 and the air inlet 112 being located at the guiding inclined surface 113, the air flow can be guided, optimizing the path for the fan 140 to inhale cold air and discharge hot air, improving the heat dissipation efficiency, reducing the turbulence in the air flow, and further reducing noise and improving the stability of the air flow. In addition, the guiding inclined surface 113 also helps to prevent dust from accumulating at the air inlet 112, maintaining the smoothness and efficiency of the heat dissipation structure.

[0088] In this embodiment, as Figure 1 and Figure 2As shown, the housing 110 has two oppositely arranged guiding inclined surfaces 113. The air inlet 112 of the air outlet 112 is located on one of the guiding inclined surfaces 113, and the air outlet 112 of the air outlet 112 is located on one of the guiding inclined surfaces 113. Along the direction away from the light source member 200, the vertical distance between the two guiding inclined surfaces 113 gradually decreases in the up and down direction. It should be noted that the inclination angle and size of the guiding inclined surface 113 can be designed according to actual needs, and this embodiment does not make specific limitations in this regard.

[0089] An embodiment of the present application also provides a lamp.

[0090] As Figure 1 and Figure 2 shown, the lamp includes a light source member 200 and the above-mentioned heat dissipation structure, and the heat dissipation member 130 is installed on the light source member 200.

[0091] It should be noted that the lamp includes, but is not limited to, stage lights, landscape lights, spotlights, etc., as long as it is a device that realizes the lighting function, and this embodiment does not make limitations in this regard.

[0093] In some embodiments, as Figure 2 shown, one side of the housing 110 along the second direction is provided with an opening. The light source member 200 includes a light-transmitting plate 201 and a substrate 202. The light-transmitting plate 201 is connected to the housing 110 and covers the opening, and a plurality of LED lamp beads distributed in an array are arranged on the surface of the substrate 202 close to the light-transmitting plate 201, and the surface of the substrate 202 away from the light-transmitting plate 201 is attached to the first section 1201 of the heat transfer member.

[0094] In some embodiments, as Figure 2 , Figure 3 and Figure 5 shown, the lamp further includes an electronic device 300 to realize the on and off of the LED lamp beads. The electronic device 300 is attached to the side of the first section 1201 of the heat transfer member away from the substrate 202 to ensure a compact structure while dissipating heat from the electronic device 300. The electronic device 300 includes, but is not limited to, a power supply.
