[0031] In order to more clearly understand the above objects, features and advantages of the present utility model, the solution of the present utility model will be further described below. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0032] Many specific details are set forth in the following description in order to fully understand the present utility model, but the present utility model can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0033] Referring to Figures 1 to 6 As shown, a kind of lamp provided by some embodiments of the present utility model includes a housing 1, a light source 3, a fixed bracket 2 and a controller 4.

[0034] Among them, the light source 3 is arranged on the housing 1, the light source 3 has positive and negative contact points, the fixed bracket 2 is provided with a conductive structure 21, one end of the conductive structure 21 forms a conductive contact 212, and the other end forms a plug-in terminal 211. The conductive contact 212 is in contact electrical connection with the positive and negative contact points. The controller 4 is arranged on the housing 1 and is in plug-in electrical connection with the plug-in terminal 211 to supply power to the light source 3 through the conductive structure 21. That is to say, the positive and negative contact points on the light source 3 are electrically connected to the controller 4 through the conductive structure 21 on the fixed bracket 2, and then the controller 4 supplies power to the light source 3 through the conductive structure 21.

[0035] Specifically, the fixed bracket 2 is fixed on the housing 1. When installing the fixed bracket 2, the light source 3 is pressed between the housing 1 and the fixed bracket 2, so that the positive and negative contact points can stably contact with the conductive contact 212. Furthermore, the problem of poor contact can be avoided. Without welding, a stable power signal can be provided to the light source 3, avoiding damage to the light source 3 due to improper operation during welding, reducing consumables, and the assembly is simple, reliable and the operation is convenient, which can improve production efficiency.

[0036] In some embodiments, referring to Figure 2As shown, a cavity structure 11 is formed inside the housing 1. Both the light source 3 and the fixing bracket 2 are disposed inside the cavity structure 11. The fixing bracket 2 can fix the light source 3 on the housing 1 and ensure the stability of the electrical connection. Specifically, the inner wall surface of the cavity structure 11 can be formed as a reflective structure to evenly disperse the light emitted by the light source 3 through the reflective inner wall, so that the light can be evenly distributed. Of course, a lens for dispersing light can also be provided inside the cavity structure 11. The present utility model does not limit this.

[0037] Specifically, the controller 4 is disposed outside the housing 1, and the plug-in terminal 211 passes through the housing 1 to be plugged and electrically connected to the controller 4. With such a setting, the controller 4 does not need to occupy the internal space of the housing 1, avoiding affecting the light emitted by the light source 3, and thus ensuring that the lamp of the present utility model can emit uniform light and improving the use performance. Specifically, the plug-in terminal 211 on the fixing bracket 2 passes through the housing 1 to realize the electrical connection between the controller 4 and the light source 3. Even if the light source 3 and the controller 4 are separately disposed inside and outside the housing 1, the fixing bracket 2 can supply power to the light source 3.

[0038] In some embodiments, referring to Figure 4 As shown, the fixing bracket 2 includes a bracket body 22 and a connecting column 23 disposed on the bracket body 22. The bracket body 22 is fixed on the housing 1, and the light source 3 is pressed between the bracket body 22 and the housing 1. That is to say, the light source 3 can be pressed between the housing 1 and the bracket body 22 through the bracket body 22, thereby ensuring the stability of the electrical connection between the light source 3 and the bracket body 22.

[0039] Referring to Figure 3 As shown, a through hole 12 communicating with the cavity structure 11 is formed on the housing 1. The connecting column 23 passes through the through hole 12 to extend outside the housing 1 for electrically connecting to the controller 4. That is to say, the bracket body 22 is disposed in the cavity structure 11 inside the housing 1, and the controller 4 is disposed outside the housing 1. The connection between the controller 4 and the bracket body 22 can be realized through the connecting column 23, and then the connection between the controller 4 and the light source 3 can be realized. It should be noted that the shape of the through hole 12 is adapted to the shape of the connecting column 23 to avoid light leakage at the through hole 12 when the connecting column 23 passes through the through hole 12.

[0040] Specifically, referring to Figure 2 As shown, the light source 3 and the controller 4 are separately disposed on the inner and outer sides of the bottom wall of the cavity structure to reduce the distance between the light source 3 and the controller 4, shorten the length of the electrical connection between the light source 3 and the controller 4, make the structure compact, and ensure the connection stability.

[0041] In specific implementation, the conductive structure 21 includes a metal conductor, and the metal conductor penetrates through the inside of the connecting post 23 and the bracket body 22 to achieve electrical connection between the controller 4 and the light source 3 through the metal conductor. In specific implementation, the metal conductor forms a plug-in terminal 211 at the end of the connecting post 23 extending outside the housing 1 for plug-in electrical connection with the controller 4, and forms conductive contacts 212 on the bracket body 22 for contact electrical connection with the positive and negative contacts on the light source 3.

[0042] It can be understood that the metal conductor is arranged inside the connecting post 23 and the bracket body 22. The connecting post 23 and the bracket body 22 can protect the metal conductor to avoid damage to the metal conductor, thereby ensuring a stable connection between the controller 4 and the light source 3 and extending the service life.

[0043] Further, referring to Figure 4 As shown, the number of positive and negative contacts is two, namely a positive contact and a negative contact. The conductive contacts 212 include a first contact and a second contact. The positive contact is in contact electrical connection with the first contact, and the negative contact is in contact electrical connection with the second contact. When the conductive structure 21 is electrically connected to the controller 4, the positive electrode of the light source 3 can be powered through the first contact of the conductive structure 21, and the negative electrode of the light source 3 can be powered through the second contact of the conductive structure 21. When both the positive and negative contacts of the light source 3 are electrically connected to the controller 4, the light source 3 can emit light.

[0044] That is to say, through the fixed bracket 2, not only can the electrical connection between the light source 3 and the controller 4 be achieved, but also the light source 3 can be arranged on the housing 1, and there is a high connection stability between the light source 3 and the housing 1, so that the light source 3 can emit light stably. In specific implementation, the first contact and the second contact are formed into a conductive copper foil structure to increase the contact area and ensure the electrical connection with the positive and negative contacts.

[0045] Specifically, the number of metal conductors is two, namely a first conductor and a second conductor. One end of the first conductor forms a first contact and provides a positive electrode electrical signal to the positive contact on the light source 3. One end of the second conductor forms a second contact and provides a negative electrode electrical signal to the negative contact on the light source 3. The other ends of the first conductor and the second conductor jointly form a plug-in terminal 211 for plug-in electrical connection with the controller 4 and transmitting electrical signals. Further, the two metal conductors are arranged side by side and embedded inside the connecting post 23 and the bracket body 22 to respectively transmit positive and negative electrode electrical signals.

[0046] In some embodiments, continue to refer to Figure 4As shown, a positioning groove 221 is provided on the fixed bracket 2, the light source 3 is arranged in the positioning groove 221, and both the first contact and the second contact are arranged on the bottom wall of the positioning groove 221. Specifically, when implemented, the shape of the positioning groove 221 is adapted to the shape of the light source 3, so as to ensure that when the light source 3 is arranged in the positioning groove 221, the positive contact and the negative contact on the light source 3 can respectively come into contact with the first contact and the second contact of the positioning groove 221 to achieve electrical connection, and the light source 3 is limited by the positioning groove 221 to ensure the contact stability between the positive contact, the negative contact and the first contact, the second contact.

[0047] In some embodiments, referring to Figure 2 and Figure 6 As shown, the controller 4 includes a plug-in mating terminal 41, and one of the plug-in terminal 211 and the plug-in mating terminal 41 is a male plug terminal and the other is a female plug terminal. That is to say, a male plug terminal can be provided on the controller 4 and a female plug terminal can be provided on the fixed bracket 2, or a female plug terminal can be provided on the controller 4 and a male plug terminal can be provided on the fixed bracket 2. The present utility model does not make a limitation on this, as long as the plug-in electrical connection between the controller 4 and the fixed bracket 2 can be realized to improve the installation efficiency.

[0048] Through the plug-in mating of the male plug terminal and the female plug terminal, the electrical connection between the controller 4 and the fixed bracket 2 can be realized. After the installation direction of the controller 4 is determined, the connection between the controller 4 and the fixed bracket 2 can be realized through plugging, without the need for additional operations such as wiring or soldering. The installation is convenient, the operation is simple, and the production efficiency can be improved. Specifically, the controller 4 can be connected to the housing 1 by means of snap connection or the like to ensure that its position on the housing 1 can be relatively fixed, thereby ensuring the stability of the electrical connection with the fixed bracket 2.

[0049] In some embodiments, the fixed bracket 2 and the conductive structure 21 are an integrally formed structure by die casting, which avoids the displacement of the conductive structure 21 inside the fixed bracket 2, ensures stable connection, and at the same time, can protect the conductive structure 21 through the fixed bracket 2 and improve the service life of the fixed bracket 2.

[0050] When specifically implemented, a first mounting hole 24 is provided on the fixed bracket 2, a second mounting hole is provided on the housing 1, and the fixed bracket 2 is connected to the housing 1 through a fastener 5 passing through the first mounting hole 24 and the second mounting hole. That is to say, the fixed bracket 2 can be firmly installed on the housing 1 through fasteners 5 such as screws, and then the light source 3 is pressed between the fixed bracket 2 and the housing 1, so that the positive and negative contacts on the light source 3 can stably contact the conductive contacts 212 on the fixed bracket 2, thereby avoiding the problem of poor contact.

[0051] Referring to Figure 4As shown, the number of the first mounting holes 24 is two, and the fixing bracket 2 is fixed on the housing 1 by two fasteners 5 passing through the first mounting holes 24, so as to be able to provide a uniform pressing force to the light source 3 and avoid damage to the light source 3 due to excessive local stress. Of course, the number of the first mounting holes 24 can also be three or more, as long as they can be evenly distributed on the fixing bracket 2 and can apply a uniform pressing force to the light source 3 to press the light source 3, and the present utility model does not limit this.

[0052] Of course, the fixing bracket 2 can also be fixed on the housing 1 by other means such as buckles, and the present utility model does not limit this, as long as the light source 3 can be pressed between the fixing bracket 2 and the housing 1 so that the positive and negative contact points on the light source 3 can stably contact the conductive contact points 212 on the fixing bracket 2.

[0053] In some embodiments, a heat-conducting layer is provided on the side of the light source 3 facing the housing 1, so that the light source 3 and the housing 1 can be in full contact, and then the heat generated on the light source 3 is transferred to the housing 1 through the heat-conducting layer and dissipated through the housing 1, avoiding overheating of the light source 3 and prolonging the service life of the lamp. Specifically, the heat-conducting layer can be a heat-conducting silicone grease layer.

[0054] Refer to Figure 5 As shown, a plurality of heat dissipation grooves 13 are provided on the outer wall surface of the housing 1, and the heat dissipation grooves 13 are formed by recessing from the outer wall surface of the housing 1 towards the inside of the housing 1. With such a setting, the area of the outer surface of the housing 1 can be increased, that is, the heat dissipation area can be increased, and then the heat dissipation performance can be increased to further prolong the service life of the lamp.
