Description

Technical Field

[0001] The present invention relates to the technical field of lamps, and in particular to a combined lamp. Background Art

[0002] When using a combination lamp, usually at least two lamp bodies are combined to increase the lighting brightness and lighting range. For example, when combining two lamp bodies, the two lamp bodies can be stacked up and down, or the two lamp bodies can be stacked left and right. For example, when combining three lamp bodies, two of the three lamp bodies can be stacked left and right, and the other can be stacked below the two lamp bodies below. For another example, when combining four lamp bodies, the four lamp bodies can be arranged in sequence in the horizontal direction, or can be stacked in sequence in the vertical direction, or can be stacked up and down in groups of two.

[0003] Regardless of the combination of lamps, if the lamps are placed adjacent to each other, the heat from the lower lamp will rise and affect the upper lamp, resulting in poor heat dissipation.

[0040] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0041] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0043] See also Figure 1-Figure 11 The present invention discloses a combined lamp, including at least two lamp bodies, specifically the lamp body includes a lamp housing 100, a light source and a heat dissipation mechanism, and the light source is installed on the lamp housing 100. A heat dissipation cavity is provided in the lamp housing 100, and the top of the heat dissipation cavity is covered with a heat dissipation top plate 10. Specifically, a first guide plate section 11 is provided on the side of the heat dissipation top plate 10, and the first guide plate section 11 is inclined outward from top to bottom. A heat dissipation port is provided on the first guide plate section 11, and the heat dissipation port is connected with the heat dissipation cavity. The heat dissipation mechanism is installed in the heat dissipation cavity, and the heat dissipation mechanism can guide the heat in the heat dissipation cavity to flow to the heat dissipation port and be discharged.

[0044] It should be noted that at least two lamp bodies are stacked up and down or left and right. When there are three or more lamp bodies, the lamp bodies can be stacked up and down or left and right. The specific combination and placement can be based on actual needs.

[0045] When two adjacent lamp bodies are stacked left and right, the first guide plate segment 11 of one lamp body cooperates with the first guide plate segment 11 of the other adjacent lamp body to form a first channel 81 .

[0046] On the basis of the above structure, when the combined lamp of the present invention is used, the light source structure of the lamp is set at the end of the lamp housing 100, and the light source can be set inside the heat dissipation cavity. In this case, a light transmission port is set on the lamp housing 100, and the light emitted by the light source in the heat dissipation cavity can be transmitted through the light transmission port. Of course, the light source can also be set in the heat dissipation cavity, that is, installed on the end plate of the lamp housing 100, and the heat generated is concentrated to the end plate of the lamp housing 100, and then the heat dissipation mechanism in the heat dissipation cavity guides the heat of the end plate of the lamp housing 100 to the heat dissipation cavity, and the heat dissipation mechanism of the heat dissipation cavity guides the heat to the heat dissipation port position for dissipation.

[0047] Take two lamp bodies as an example for explanation. The two lamp bodies can be stacked up and down or left and right.

[0048] See also Fig. 9 When the lamp bodies are stacked up and down, during heat dissipation, since the heat dissipation port is arranged on the first guide plate section 11 of the heat dissipation top plate 10, the first guide plate section 11 is arranged in an inclined state. Based on the inclined surface, the airflow can be blocked from directly flowing upward, and the airflow can be guided to be discharged in the inclined direction. Therefore, the heat discharged from the heat dissipation port is not directly guided upward, so that the heat discharged from the heat dissipation port of the lower lamp body can avoid the upper lamp body, preventing the heat of the lower lamp body from directly rising and causing overheating of the upper lamp body.

[0049] The heat dissipated from the heat dissipation port of the upper lamp body can also avoid other devices or devices above the lamp body, thereby preventing the heat dissipated in the heat dissipation shell from being concentrated on the structure above the lamp body.

[0050] See also Fig.10 When the lamp bodies are stacked left and right, since the first guide plate sections 11 are provided on both sides of the heat dissipation top plate 10 of the lamp housing 100, when the two lamp bodies are stacked left and right, a first guide plate section 11 of the lamp body on the left and a first guide plate section 11 on the right can cooperate to form a "V"-shaped first channel 81, and the first channel 81 can provide gas flow, so as to take away the heat dissipated through the heat dissipation port. In this way, there is a channel for gas flow after the two lamp bodies are stacked left and right, thereby effectively preventing heat from rising and improving the heat dissipation effect.

[0051] Taking three lamp bodies as an example, the two lamp bodies can be stacked up and down, or stacked left and right. The three lamp bodies are respectively the first lamp body, the second lamp body and the third lamp body. When they are combined and stacked, the three lamp bodies are placed in a triangle, that is, the first lamp body and the second lamp body are stacked up and down, and the second lamp body and the third lamp body swing left and right.

[0052] Similarly, when the first lamp body and the second lamp body stacked adjacent to each other are dissipating heat, since the heat dissipation port is arranged on the first guide plate segment 11 of the heat dissipation top plate 10, the first guide plate segment 11 is arranged in an inclined state. Based on the inclined surface, the airflow can be blocked from directly flowing upward and the airflow can be guided to be discharged in the inclined direction. Therefore, the heat discharged from the heat dissipation port is not directly guided upward, so that the heat discharged from the heat dissipation port of the second lamp body below can avoid the first lamp body above, preventing the heat of the second lamp body below from rising directly and causing overheating of the first lamp body above.

[0053] When the second lamp body and the third lamp body are stacked left and right, since the first guide plate segments 11 are provided on both sides of the heat dissipation top plate 10 of the lamp housing 100, when the two lamp bodies are stacked left and right, the first guide plate segment 11 on the left side of the second lamp body and the first guide plate segment 11 on the right side of the third lamp body can cooperate to form a "V"-shaped first channel 81. The first channel 81 can provide gas flow, thereby taking away the heat dissipated through the heat dissipation port. In this way, after the two lamp bodies are stacked left and right, there is a channel for gas flow, thereby effectively preventing heat from rising and improving the heat dissipation effect.

[0054] Of course, four or more lamp bodies can be provided, and the arrangement can be selected according to actual needs.

[0055] That is to say, the heat in the heat dissipation cavity of the lamp housing 100 can flow to the inclined first guide plate, and the heat conducted through the heat dissipation opening on the inclined first guide plate segment 11 can be directly conducted to the outside without affecting the lamp body or structure adjacent thereto. In addition, the inclined first guide plate segment 11 is used as a heat conduction surface, and the inclined guide surface formed can increase the contact area between the heat dissipation component and the air or heat dissipation medium, thereby improving the heat transfer efficiency. The inclined guide surface can be decomposed into a horizontal and a vertical heat dissipation surface, and such a heat dissipation surface is relatively larger.

[0056] The up and down directions referred to in this embodiment can refer to the Y-axis direction in each drawing, and the inside and outside directions referred to in this embodiment can refer to the X-axis direction in each drawing. Due to the different viewing angles in different drawings, the Y-axis direction and the X-axis direction have different directions. The specific up and down directions can be the vertical direction when the product is actually used as the up and down directions, and the inside and outside directions can be the space inside the heat dissipation cavity of the shell as the inside, and the space outside the heat dissipation cavity of the shell as the outside. Of course, the specific direction is selected according to the actual needs of the product.

[0057] Furthermore, the heat dissipation port is provided with a plurality of partition bars 112 arranged at intervals, and the extension direction of each partition bar 112 is consistent with the inclination direction of the first guide plate segment 11 , that is, the partition bars 112 are also arranged at an inclination, and the interval between two adjacent partition bars 112 forms a first heat dissipation hole 111 .

[0058] On the basis of this structure, when heat is dissipated, the heat in the heat dissipation cavity flows to the heat dissipation port position, the heat is dispersed by multiple partition bars 112, and then dissipated through the first heat dissipation hole 111 position between two adjacent partition bars 112. That is to say, the heat in the heat dissipation cavity can be dispersed and exported, and the partition bars 112 disperse the heat to different areas and directions to avoid the heat being concentrated in one place.

[0059] It should be emphasized that since multiple partition bars 112 are arranged at the heat dissipation port to form multiple first heat dissipation holes 111, the heat dissipation paths and channels are increased, and heat can be dissipated through multiple paths, reducing the resistance to heat transfer, thereby improving the heat dissipation efficiency.

[0060] Furthermore, the bottom end of the heat dissipation cavity may be covered with a heat dissipation bottom plate 30, and a plurality of second heat dissipation holes 311 may be provided on the heat dissipation bottom plate 30, and the plurality of second heat dissipation holes 311 are connected to the heat dissipation cavity. Specifically, the second heat dissipation holes 311 in this embodiment may also be selected as honeycomb holes in the prior art.

[0061] In this way, when heat is dissipated inside the heat dissipation cavity, air convection needs to be maintained to achieve more efficient heat dissipation. In this way, the second heat dissipation holes 311 on the heat dissipation base plate 30 at the bottom are used as air inlets. Multiple second heat dissipation holes 311 can guide the bottom airflow to be dispersed and introduced into the heat dissipation cavity, and can be evenly distributed to various positions of the heat dissipation cavity for uniform guidance.

[0062] In addition, based on the structure of the second heat dissipation holes 311 being honeycomb holes, the shape and arrangement of the honeycomb holes are conducive to guiding air flow. When air flows through the honeycomb holes, a natural convection channel is formed, hot air rises, and cold air is replenished, accelerating the dissipation of heat.

[0063] Furthermore, a second guide plate section 32, a heat dissipation plate section 31 and a baffle section are provided on both sides of the heat dissipation bottom plate 30, and the second guide plate section 32 is gradually inclined outward from bottom to top. The baffle section is provided at the bottom end of the second guide plate section 32 and the connecting position of the heat dissipation plate section 31, and a plurality of the above-mentioned second heat dissipation holes 311 are provided on the heat dissipation plate section 31.

[0064] Since a plurality of second heat dissipation holes 311 are provided at the bottom end of the heat dissipation base plate 30 for introducing external airflow into the bottom end of the heat dissipation cavity, when the upper and lower lamp bodies are stacked, the baffle section of the heat dissipation base plate 30 of the upper lamp body can be against the top of the lower lamp body. The baffle section can leave a gap between the upper and lower lamp bodies, allowing gas to flow to the bottom of the heat dissipation base plate 30, thereby facilitating the airflow to be introduced into the heat dissipation cavity through the plurality of second heat dissipation holes 311.

[0065] When the upper and lower lamp bodies are stacked, the upper second guide plate section 32 is gradually tilted outward from bottom to top, and the lower first guide plate section 11 is gradually tilted outward from top to bottom. In this way, when the first guide plate section 11 guides the heat to be discharged in the inclined direction, if there is some heat that will directly rise, it can also flow to the upper second guide plate section 32. The second guide plate section 32 can also guide the heat to flow outward, and at the same time cooperate with the baffle section to prevent the heat dissipated from the heat dissipation port of the lower lamp body from entering the second heat dissipation hole 311.

[0066] When two adjacent left and right lamp bodies are stacked, the left and right sides of the two lamp shells 100 are abutted against each other, and the second guide plate section 32 located at the bottom end side of one of the lamp shells 100 can cooperate with the second guide plate section 32 at the bottom end side of the other lamp shell 100 to form a second channel 82 for air flow. In combination with the first channel 81 at the top position, channels for air flow can be formed above and below the lamp shells 100, so that the heat dissipation effect between the stacked lamp bodies on the left and right is good.

[0067] When there are two lamp bodies in the upper and lower parts, refer to Fig.11 That is, when there are four lamp bodies, the first channels 81 and the second channels 82 of the upper and lower lamp bodies can be enclosed with each other to form a gas flow channel, so that an air flow channel is formed between the four lamp bodies, and the heat conduction effect is better.

[0068] Furthermore, the baffle section is arranged at the connecting position of the bottom end of the heat dissipation plate section 31 and the second guide plate section 32. The baffle section can further block the upward heat from avoiding the second heat dissipation hole 311, and prevent the heat discharged from the lower heat dissipation from being introduced again through the second heat dissipation hole 311 above, thereby improving the heat dissipation efficiency.

[0069] Furthermore, the heat dissipation top plate 10 also includes a connecting plate section 12, on which a concave flow guide groove 121 is provided; the top of the first guide plate section 11 is connected with the connecting plate section 12, and when two adjacent lamp bodies are stacked up and down, the heat dissipation bottom plate 30 of one lamp body abuts against the connecting plate section 12 of the other lamp body, so that the flow guide groove 121 cooperates with the heat dissipation bottom plate 30 to form a third channel. In this way, when the upper and lower lamp bodies are stacked, the second heat dissipation holes 311 of the heat dissipation bottom plate 30 at the bottom of the upper lamp body will not be sealed by the heat dissipation top plate 10 of the lower lamp body, and the flow guide groove 121 forms a third channel in its own length direction, guides the gas flow, and introduces it into the multiple second heat dissipation holes 311 of the heat dissipation bottom plate 30. In this way, the heat dissipation performance of the combined lamp formed as a whole is better.

[0070] More specifically, further, in this embodiment, both sides of the connecting plate segment 12 are provided with third guide plate segments 122, and the third guide plate segments 122 on both sides are inclined. Specifically, the inclination direction of the third guide plate segment 122 is opposite to the inclination direction of the first guide plate segment 11. The top of the third guide plate segment 122 is connected to the top of the first guide plate segment 11, so that the third guide plate segment 122 can guide the gas in the heat dissipation cavity to be discharged toward the heat dissipation port. Based on this structure, the above-mentioned guide groove 121 can be formed between the two third guide plate segments 122.

[0071] Based on this structure, when the gas in the heat dissipation cavity flows upward and dissipates, since the heat dissipation top plate 10 is sealed on the top of the heat dissipation cavity, the gas flowing upward can directly flow to the first guide plate sections 11 on both sides. Since the first guide plate sections 11 gradually tilt outward from top to bottom, the heat dissipation port arranged on the first guide plate section 11 can directly tilt the airflow flowing to the first guide plate section 11 outward.

[0072] At the same time, the connecting plate section 12 is located in the middle position of the two first guide plate sections 11, so the gas flowing in the middle position of the heat dissipation cavity will be guided upward by the third guide plate sections 122 on both sides. The inclination direction of the third guide plate section 122 is opposite to the inclination direction of the first guide plate section 11, so the third guide plate section 122 guides from bottom to top and tilts outward. In this way, when the airflow in the middle position flows to the third guide plate section 122, the third guide plate section 122 will guide the gradually rising airflow to the heat dissipation port of the first guide plate section 11, so that the heat dissipation efficiency is higher.

[0073] In addition, the third guide plate segments 122 on both sides of the connecting plate segment 12 can enclose and form the above-mentioned guide groove 121 to guide the flow of air. There is no need to additionally process the above-mentioned guide groove 121, which can be formed by enclosing the inclined plate segments.

[0074] Furthermore, the heat dissipation mechanism includes a plurality of heat sinks 41 and heat dissipation tubes 42. The plurality of heat sinks 41 are arranged at intervals in the heat dissipation cavity, and the heat dissipation tubes 42 are sequentially passed through the plurality of heat sinks 41. In this way, heat dissipation can be achieved by combining the heat dissipation tubes 42 and the plurality of heat sinks 41. Specifically, a cooling fluid can be introduced into the heat dissipation tubes 42. The heat dissipation tubes 42 can extend to the heat-generating components. A cooling fluid (such as a cooling air flow or a cooling liquid flow, etc.) can be introduced into the heat dissipation tubes 42. The heat-generating components are cooled after heat exchange by the heat dissipation tubes 42. Then, the portion of the heat dissipation tubes 42 connected to the plurality of heat sinks 41 can exchange heat with the heat sinks 41 at different positions, thereby quickly dissipating the heat.

[0075] Specifically, a cooling fan 43 can also be set at the bottom end of the cooling cavity. When cooling, the cooling fan 43 rotates at the bottom end of the cooling cavity to guide the flow of airflow, accelerate the airflow to be introduced from the multiple second cooling holes 311 of the cooling base plate 30, and disperse the airflow through each cooling fin 41, so that the heat is dispersed and flows quickly to the cooling port, thereby accelerating the heat flow and improving the cooling efficiency.

[0076] Further, see Figure 2 , Figure 6 , Figure 7 as well as Figure 8 The lamp body also includes a lamp holder 50, and the lamp housing 100 of the lamp body is mounted on the lamp holder 50. The lamp holder 50 includes two sets of connecting edge components, and the connecting edge components include a first connecting edge 51 and a second connecting edge 52, and the first connecting edge 51 and the second connecting edge 52 are arranged opposite to each other and spaced apart. A first locking member 60 is provided on the first connecting edge 51, and a second locking member 70 is provided on the second connecting edge 52. When the lamp holders 50 are stacked, the first connecting edge 51 of one lamp holder 50 abuts against the second connecting edge 52 of the adjacent lamp holder 50.

[0077] Specifically, the first locking member 60 moves along a locking direction under the action of an external force. The second locking member 70 is provided with a pressure section and a locking section. When the first connecting edge 51 abuts against the second connecting edge 52, the first locking member 60 moves along the locking direction and can be connected to the second locking member 70 and press the pressure section of the second locking member 70. The pressure section can press to drive the locking section to connect and lock with the second connecting edge 52.

[0078] The first connecting edge 51 and the second connecting edge 52 of one group of connecting edge components are spaced apart above and below the lamp holder 50, and the first connecting edge 51 and the second connecting edge 52 of the other group of connecting edge components are spaced apart on the left and right sides of the lamp holder 50. In this way, the lamp holder 50 has four connecting edges, and the first connecting edge 51 and the second connecting edge 52 are spaced apart on the upper and lower sides of the lamp holder 50, and the first connecting edge 51 and the second connecting edge 52 are spaced apart on the left and right sides of the lamp holder 50.

[0079] On the basis of this structure, when at least two lamp bodies are used in combination, the lamp holder 50 of the lamp body is used in combination.

[0080] See also Fig. 9 In the case where two lamp bodies are provided, the two lamp holders 50 are stacked up and down in combination:

[0081] During assembly, one of the lamp stands 50 is placed on top of the other lamp stand 50. In this case, the first connection edge 51 of the upper lamp stand 50 can be abutted against the second connection edge 52 of the lower lamp stand 50. At this time, the first locking member 60 on the upper side corresponds to the second locking member 70 on the lower side. After that, the locking action of the stacked lamp stands 50 begins. The user can hold the first locking member 60 to drive the first locking member 60 to move downward. After the first locking member 60 moves downward, it is connected to the second locking member 70. At the same time, after the first locking member 60 is connected to the second locking member 70, the pressure section of the second locking member 70 can be pressed downward. After the pressure section is pressed, the locking section of the second locking member 70 can be linked to lock with the second connection edge 52. In this way, the first locking member 60 of the first connection edge 51 is connected to the second locking member 70, and the second locking member 70 is locked with the second connection edge 52 at this time. In this way, the first connection edge 51 and the second connection edge 52 can be locked, and the two lamp stands 50 can be locked up and down.

[0082] See also Fig.10 Of course, when there are two lamp bodies, the two lamp holders 50 can also be stacked left and right, so that the first connecting edge 51 of the right lamp holder 50 is abutted against the second connecting edge 52 of the left lamp holder 50. When locking, the user can hold the first locking piece 60 to drive the first locking piece 60 to move to the left. After moving to the left, the first locking piece 60 is connected to the second locking piece 70. At the same time, after the first locking piece 60 is connected to the second locking piece 70, the compressed section of the second locking piece 70 can be pressed to the left. After the compressed section is compressed, the locking section of the second locking piece 70 can be linked to lock with the second connecting edge 52. In this way, the first locking piece 60 of the first connecting edge 51 is connected to the second locking piece 70, and the second locking piece 70 is locked with the second connecting edge 52 at this time. In this way, the locking of the first connecting edge 51 and the second connecting edge 52 can be achieved, and the two lamp holders 50 can be locked left and right.

[0083] It should be noted that when the lamp holders 50 are stacked up and down, the locking direction is the up and down direction, and when the lamp holders 50 are stacked left and right, the locking direction is the left and right direction. In addition, when unlocking, the first locking member 60 is driven away from the second locking member 70 by an external force, and the first locking member 60 is disengaged from the second locking member 70, and the lock is released.

[0084] When there are three lamp bodies, in this case, the lamp holders 50 of the three lamp bodies are respectively the first lamp holder 50, the second lamp holder 50 and the third lamp holder 50 for explanation, and the three lamp holders 50 are arranged in a triangle, that is, the first lamp holder 50 and the second lamp holder 50 are stacked up and down, and the second lamp holder 50 and the third lamp holder 50 are arranged left and right:

[0085] The second lamp holder 50 is placed above the first lamp holder 50, the first connecting edge 51 of the second lamp holder 50 abuts against the second connecting edge 52 of the first lamp holder 50, and the first connecting edge 51 of the third lamp holder 50 abuts against the second connecting edge 52 of the first lamp holder 50. After the assembly is completed, the user can hold the first locking piece 60 of the second lamp holder 50 to drive the first locking piece 60 to move downward. After the downward movement, the first locking piece 60 is connected to the second locking piece 70 of the second lamp holder 50. At the same time, after the first locking piece 60 is connected to the second locking piece 70, the compressed section of the second locking piece 70 can also be pressed downward. After the compressed section is compressed, the locking section of the second locking piece 70 can be linked to lock with the second connecting edge 52. In this way, the first locking piece 60 of the first connecting edge 51 is connected to the second locking piece 70, and the second locking piece 70 is locked with the second connecting edge 52 at this time. In this way, the locking of the first connecting edge 51 and the second connecting edge 52 can be achieved, and the first lamp holder 50 and the second lamp holder 50 can be locked up and down.

[0086] The user can hold the first locking piece 60 of the third lamp holder 50 to drive the first locking piece 60 to move to the left. After moving downward, the first locking piece 60 is connected to the second locking piece 70 of the first lamp holder 50. At the same time, after the first locking piece 60 is connected to the second locking piece 70, the compressed section of the second locking piece 70 can be pressed to the left. After the compressed section is compressed, the locking section of the second locking piece 70 can be linked to lock with the second connecting edge 52. In this way, the first locking piece 60 of the first connecting edge 51 is connected to the second locking piece 70, and the second locking piece 70 is locked with the second connecting edge 52 at this time. In this way, the locking of the first connecting edge 51 and the second connecting edge 52 can be achieved, and the first lamp holder 50 and the third lamp holder 50 can be locked left and right.

[0087] That is to say, when four lamp bodies are provided, the four lamp stands 50 of the four lamp bodies are all provided with a connecting structure, which can realize the combined use of multiple lamp stands 50 in different directions, and the use scenarios are more diverse and flexible.

[0088] In the present application, when the lamp body is assembled, the first connecting edge 51 and the second connecting edge 52 of two adjacent lamp holders 50 are correspondingly abutted, and the first locking member 60 of the first connecting edge 51 of one lamp holder 50 and the second locking member 70 of the second connecting edge 52 of the other lamp holder 50 are used to lock or unlock. The first locking member 60 presses against the second locking member 70 after the movement to achieve locking. When the first locking member 60 is disassembled, it can be reset to separate from the second locking member 70 to complete the unlocking, so that no additional tools are required. In addition, the first locking member 60 and the second locking member 70 are both connected to the lamp holder 50. When the assembly is well aligned, the locking action can be started directly. The locking position is accurate, and no hand support is required, and the locking process is simple.

[0089] Specifically, a locking groove 722 may be provided on the second connecting edge 52, and the second locking member 70 includes two locking arms 71. Based on this structure, a compression section is provided at one end of the locking arm 71, and a locking section is provided at the other end of the locking arm 71. The two locking arms 71 are provided in the locking groove 722, and a locking gap 73 is formed between the force-bearing ends of the two locking arms 71. The first locking member 60 is used to be inserted into the locking gap 73 along the locking direction to press the compression section and drive the locking sections of the two locking arms 71 to connect and lock with the side walls of the locking groove 722.

[0090] When two lamp stands 50 are combined, the first connecting edge 51 of one lamp stand 50 abuts against the second connecting edge 52 of the other lamp stand 50, and the first locking member 60 on the first connecting edge 51 corresponds to the second locking member 70 on the second connecting edge 52. When locking, when the first locking member 60 moves along the locking direction, the first locking member 60 can move toward the locking interval 73 between the two locking arms 71 of the locking member, and the first locking member 60 can be inserted into the locking interval 73, so that the connection relationship with the second locking member 70 can be maintained through the locking interval 73. At the same time, when the first locking member 60 is inserted into the locking interval 73, the force-bearing sections of the two locking arms 71 can be pressed to drive the two locking arms 71 away from each other, so that the locking sections of the two locking arms 71 can be locked and pressed against the side walls of the locking groove 722 to maintain the locked state.

[0091] When unlocking, the first locking member 60 is driven to withdraw from the locking interval 73 between the two locking arms 71, so that the first locking member 60 is disengaged from the second locking member 70, and at the same time, the external force of the force-bearing section of the locking arm 71 is removed, and the locking arm 71 can be disengaged from the side wall of the locking groove 722 to release the lock.

[0092] Specifically, the second locking member 70 further includes an elastic component 74, which is connected between the two locking arms 71. The elastic component 74 can provide an elastic stress, under which the two locking arms 71 can maintain a state of being close to each other.

[0093] Based on this structure, when the second locking member 70 is not in a combined use state, the two locking arms 71 can be close to each other under the action of the elastic member 74, that is, they are kept unlocked from the second connecting edge 52. When the locking action is performed, the first locking member 60 is inserted into the locking interval 73 between the two locking arms 71. During the insertion of the first locking member 60, the two locking arms 71 are driven to open, and the elastic member 74 can be stretched. The locking section of the locking arm 71 can be kept pressed against the side wall of the locking groove 722 under the pressure of the first locking member 60. At the same time, the elastic member 74 is stretched at this time and keeps the return state. The elastic stress of the stretched elastic member 74 can be applied to the first locking member 60 between the two locking arms 71, so that the first locking member 60 can be pressed by the two locking arms 71, so that the locking structure is more stable.

[0094] Of course, when the elastic component 74 is provided, the force of the elastic component 74 can keep the force-bearing section of the second locking member 70 disengaged from the second connecting edge 52 and located in the locking direction of the first locking member 60, so that the first locking member 60 can press against the force-bearing section of the locking arm 71 when moving along the locking direction, overcome the elastic stress, and drive the locking section of the second locking member 70 to overcome the elastic stress and lock toward the second connecting edge 52.

[0095] In the case where the elastic component 74 is not provided, a compressive slope can be provided in the force-bearing section of the second locking member 70. After the first locking member 60 moves along the locking direction, the compressive slope can be pressed to decompose the force, thereby driving the locking section of the second locking member 70 to move toward the second connecting edge 52, and also maintaining the locked state.

[0096] Specifically, the elastic component 74 in this embodiment can be selected as a spring structure in the prior art. In other cases, the elastic component 74 can also be implemented as an elastic rubber block or other structure in the prior art.

[0097] Furthermore, in order to ensure that the locking arm 71 of the second locking member 70 and the locking groove 722 maintain a stable locking state, a connecting groove 723 can be provided on the side wall of the locking groove 722, and a connecting block 711 is provided on the locking section accordingly. The connecting block 711 can be inserted into the connecting groove 723 when the pressure section is under force.

[0098] When locking, the first locking piece 60 is inserted into the locking gap 73 between the two locking arms 71 under the action of external force, so that the two locking arms 71 can be driven to open, and then the locking section of the locking arm 71 is linked to set the connecting block 711 to move toward the connecting groove 723 on the side wall of the locking groove 722, and the locking block can be inserted into the connecting groove 723, so that the locking arm 71 remains in a locked state with the locking groove 722.

[0099] Of course, the above-mentioned connecting groove 723 can pass through to the outer end face of the second connecting edge 52, so that when unlocking, after the first locking piece 60 withdraws from the locking interval 73 between the two locking arms 71, it can apply force to the connecting block 711 in the connecting groove 723 through the connecting groove 723, driving the connecting block 711 to withdraw from the connecting groove 723, so that the two locking arms 71 can be in an unlocked state with the locking groove 722.

[0100] In the case where the connecting block 711 and the connecting groove 723 are not provided, the buckle 712 may be provided on the locking section of the locking arm 71, and a corresponding slot structure may be provided on the inner wall of the locking groove 722, so that when the locking arm 71 is pressed against the side wall of the locking groove 722, the buckle 712 and the slot are kept in a locked state. In addition, locking teeth may be provided on the locking section of the locking arm 71, and a tooth groove structure may be provided on the side wall of the locking groove 722, so that when the locking arm 71 is in contact with the side wall of the locking groove 722, the locking arm 71 and the tooth groove structure may be kept in a toothed and locked state. In short, only when the locking arm 71 is in contact with the side wall of the locking groove 722, the locking section of the locking arm 71 can lock the locking groove 722 to a limited position, can the structure be realized.

[0101] Alternatively, on the basis of a structure without setting the locking groove 722, other limiting structures, such as a protrusion, can be directly set on the second connecting edge 52. After being compressed, the locking arm 71 can drive the locking section to move toward the protrusion and abut it. In order to maintain a stable locking state, a magnet structure can also be set on the second connecting edge 52, and a corresponding magnet structure can be set on the locking section of the locking arm 71. When the locking arm 71 is forced to drive the locking section to approach the second connecting edge 52 for locking, the locking limit can also be achieved by the magnetic attraction between the magnet and the magnet.

[0102] Furthermore, a mounting groove may be provided on the second connecting edge 52, and the second locking member 70 may further include a locking seat 72, and the locking groove 722 is provided on the locking seat 72. When the second locking member 70 is assembled with the second connecting edge 52, the locking seat 72 of the second locking member 70 is installed in the mounting groove, and a through hole corresponding to the connecting groove 723 is provided on the side wall of the mounting groove.

[0103] In this way, the second locking piece 70 is formed by a locking seat 72 and two locking arms 71. The two locking arms 71 of the second locking piece 70 can be first assembled with the locking groove 722 of the locking seat 72, and then the locking seat 72 can be assembled into the installation groove of the second connecting edge 52 of the lamp holder 50. That is, the second locking piece 70 is assembled separately on the outside of the lamp holder 50, and then assembled. In this way, during the processing of the lamp holder 50, only the main structure of the lamp holder 50 needs to be processed, and the locking structure can be assembled later.

[0104] When the two lamp holders 50 are combined and locked, the first locking piece 60 is inserted into the locking gap 73 between the two locking arms 71 of the locking seat 72, and the connecting block 711 of the two locking arms 71 can be inserted into the connecting groove 723 of the locking seat 72 and pass through the through-hole of the second connecting edge 52, so that locking can be achieved. When unlocking, the connecting block 711 structure can be pushed out with the through-hole position of the second connecting edge 52.

[0105] In order to further ensure the accurate locking position of the first locking member 60 and the second locking member 70, two positioning arms 721 may be further provided on the locking seat 72. The two positioning arms 721 are arranged around the top periphery of the locking groove 722 and are staggered with the two locking arms 71. When locking, since the two positioning arms 721 are fixedly arranged on the locking seat 72, the interval position between the two positioning arms 721 is fixed. When the first locking member 60 and the second locking member 70 are locked, the first locking member 60 can be inserted through the interval between the two positioning arms 721. The fixed interval guidance makes the insertion process more stable compared to the guidance by the movable locking interval 73.

[0106] Furthermore, a through groove 511 may be provided on the first connecting edge 51, and the first locking member 60 may be connected to the through groove 511, so that when the first locking member 60 moves along the locking direction, it is guided by the through groove 511, so that the locking direction of the first locking member 60 is more stable.

[0107] More importantly, when the first locking piece 60 is locked with the second locking piece 70, since the first connecting edge 51 and the second connecting edge 52 are abutted against each other, in order to keep the first connecting edge 51 and the second connecting edge 52 in a tightly fitted and abutted locked state, after the first locking piece 60 is inserted into the locking interval 73, the force-bearing sections of the two locking arms 71 on the second connecting edge 52 can also be inserted into the through-groove 511 on the first connecting edge 51, so that the first locking piece 60 is locked to the second connecting edge 52, and the second locking piece 70 is locked to the first connecting edge 51, and they are locked with each other, so that the locking state is more stable.

[0108] More specifically, a buckle 712 is provided on the force-bearing section. When locked with each other, the locking arm 71 of the second locking member 70 passes through the through-connection groove 511, and the buckle 712 structure of the force-bearing section of the locking arm 71 can pass through the through-connection groove 511 and engage with the first connecting edge 51.

[0109] On the basis of this structure, since a buckle 712 structure is provided on the force-bearing section, if an elastic component 74 is provided, the elastic stress provided by the elastic stress makes the buckle 712 structure of the second locking member 70 correspond to the connecting groove 511 structure of the first connecting edge 51, so that when the first connecting edge 51 and the second connecting edge 52 are abutted, the buckle 712 of the second locking member 70 can be correspondingly inserted into the connecting groove structure, and at the same time, the first locking member 60 penetrates into the locking groove 722 to synchronously complete the two-way locking.

[0110] If the elastic component 74 is not provided, force can be applied manually to the force-bearing section of the second locking member 70, such as applying force to the connecting block 711, to drive the connecting block 711 to withdraw from the connecting groove 723. The buckle 712 of the locking arm 71 can correspond to the through-groove 511 structure of the first connecting edge 51 and can also realize two-way locking.

[0111] Furthermore, in order to facilitate the operation of the first locking member 60, the above-mentioned first locking member 60 also includes a pressing arm 61, one end of the pressing arm 61 is hinged to the first connecting edge 51, and the other end of the pressing arm 61 is hinged to the top of the first locking member 60. In this structure, the user only needs to hold the pressing arm 61, so that the pressing arm 61 uses the hinge point hinged to the first connecting edge 51 as a fulcrum to drive the first locking member 60 at the other end to move accordingly, thereby realizing the locking or unlocking action.

[0112] It should be noted that the light source in this embodiment includes a lamp board 22, lamp beads 23 and a light guide cover 21. The lamp board 22 is arranged at the installation opening and is arranged corresponding to the heat dissipation mechanism. Then the lamp beads 23 are installed on the lamp board 22 and are electrically connected to the lamp board 22. The light guide cover 21 is arranged around the outer periphery of the installation opening. Based on this structure, when the lamp is in use, the lamp board 22 is located in the heat dissipation cavity. When the lamp beads 23 are working, the heat generated can be guided to the heat dissipation opening through the heat dissipation mechanism in the heat dissipation cavity for dissipation, and the heat dissipation is directly performed by the heat dissipation mechanism.

[0113] The light guide cover 21 can be arranged outside the installation opening, and the light guide cover 21 can guide the light generated by the lamp beads 23 to be guided out after refraction or reflection, so that the guided light has a better effect.

[0114] Of course, the lamp board 22 can be directly facing the heat dissipation mechanism. When the heat dissipation mechanism includes multiple heat sinks 41 and heat pipes 42, the heat pipes 42 can be connected to the position of the lamp board 22, and the heat dissipation of the lamp board 22 can be directly carried out by the heat pipes 42. The heat is introduced to flow to the multiple heat sinks 41 for heat extraction. In this way, the heat dissipation is directly carried out on the heating structure of the light source of the lamp, and the heat dissipation effect is good, which can prevent damage caused by overheating of the light source.

[0115] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
