For example, the material of the second light-transmitting region is glass or PC (Polycarbonate), PMMA (Polymethyl Methacrylate), MABS (methyl Methacrylate-acrylonitrile-butadiene-styrene plastic), PETG (ethylene terephthalate-1, 4-cyclohexylenedimethylene terephthalate, Polyethylene terephthalate-1, 4-cyclohexanedimethanol), AS (acrylonitrile-styrene copolymer), PS (Polystyrene ), acryl (acrylic copolymer), PVC (Polyvinyl chloride), PET (Polyethylene terephthalate), or the like. In this embodiment, the material of the second light-transmitting region is glass.
In order to improve the heat dissipation efficiency of the housing, for example, the lamp further includes a metal heat conduction frame welded to the housing, so that heat on the housing is conducted to the metal heat conduction frame, and the heat is exchanged with the outside air through the metal heat conduction frame, so that the housing can dissipate heat well. For another example, the cross section of the metal heat conducting frame is rectangular. For example, the metal heat conducting frame is made of aluminum, so that the metal heat conducting frame is light in weight and good in heat conducting performance, and heat on the shell is quickly conducted to the metal heat conducting frame. It is understood that, in other embodiments, the material of the metal heat conducting frame may also be copper, so that the heat conducting performance of the metal heat conducting frame is better.
In order to further improve the heat conduction rate of the shell, for example, the lamp further comprises heat dissipation fins, and the heat dissipation fins are arranged on the metal heat conduction frame, so that heat on the metal heat conduction frame exchanges heat with outside air through the heat dissipation fins, and the shell has a higher heat conduction rate. For another example, the number of the heat dissipation fins is multiple, and the multiple heat dissipation fins are uniformly arranged on the metal heat conduction frame, so that the heat conduction efficiency of the metal heat conduction frame is higher. For another example, the plurality of heat-conducting fins are arranged in a rectangular array, so that the heat-conducting effect of the shell is better.
For example, the outer wall of each heat-conducting fin is provided with a plurality of convection grooves, so that air flow enters the convection grooves to exchange heat with the heat-conducting fins. For another example, the convection grooves are distributed at intervals along the circumferential direction of the heat-conducting fins, so that the heat-conducting fins have better heat dissipation performance. For another example, the cross section of each convection groove is triangular, so that the contact area between the convection groove and air is larger, and the heat dissipation efficiency of the heat conduction fins is improved. For example, each heat conduction fin is provided with an air inlet groove and a side wall hole which are communicated with each other, so that air flow can sequentially pass through the air inlet groove and the side wall hole, and the heat conduction fins are in good contact with the air flow. For another example, the side wall hole is opened on the inner wall of the convection groove, that is, the side wall hole is communicated with the convection groove, so that part of the air flow in the contact process with the convection groove enters the ventilation groove through the side wall hole, and the heat-conducting fin has a better heat dissipation effect. For another example, the number of the side wall holes is plural, and the plural side wall holes are distributed at intervals along the extending direction of the convection slot. For another example, the distance between two adjacent side wall holes is 3 mm-5 mm, so that the air circulation effect between the air flow and the convection groove is better, and the heat dissipation effect of the heat conduction fins is better.
In the lamp, the housing is provided with the accommodating groove, the supporting seat is positioned in the accommodating groove and connected with the housing, the number of the light-emitting assemblies is multiple, and the heat-conducting columns of the light-emitting assemblies are distributed at intervals along the circumferential direction of the supporting seat, so that the heat-conducting columns of the supporting seat are distributed uniformly along the circumferential direction; the first lamp bead and the second lamp bead are respectively positioned on two sides of the heat conduction column, so that two sides of the heat conduction column can better emit light, heat generated by the light emission of the first lamp bead and the second lamp bead is conducted to the heat conduction column, and because two ends of the heat conduction column of each light-emitting assembly are respectively connected with the shell and the supporting seat, part of the heat on the heat conduction column can be conducted to the shell and the supporting seat, and part of the heat is subjected to heat exchange with air around the heat conduction column, so that the heat dissipation efficiency of the heat conduction column is ensured; the heat conducting columns are connected with the heat conducting plate, and the heat conducting plate is positioned on one side of each heat conducting column, which is far away from the shell, so that the heat on the heat conducting columns can be partially conducted onto the heat conducting plate for heat dissipation, the heat conducting efficiency of the heat conducting columns is improved, the problem that the lamp beads are too much in accumulated heat and even burnt out is solved, and the service life of the lamp beads is longer; the heat-conducting plate is provided with the first light-transmitting area, so that light rays generated by the first lamp beads and the second lamp beads can penetrate through the heat-conducting plate, and the lighting effect of the lamp is ensured; the heat conducting plate is provided with an avoiding groove and a plurality of first open grooves, each first open groove corresponds to each heat conducting column, the rotating assembly is arranged on the supporting seat and is positioned in the avoiding groove, the cover plate is arranged on the power output end of the rotating assembly, the rotating assembly drives the cover plate to rotate relative to the heat conducting plate, the cover plate is provided with a plurality of second open grooves, and because the included angle of the extending directions of two adjacent second open grooves is equal to the included angle of the extending directions of two adjacent first open grooves, and the number of the first open grooves is equal to that of the second open grooves, the area of each first open groove is equal to that of each second open groove; when the lamp is turned on, the driving component drives the cover plate to positively rotate to a preset angle relative to the heat conducting plate, so that each second open slot of the cover plate corresponds to each corresponding first open slot, and light rays emitted by the first lamp beads and the second lamp beads can better penetrate through the cover plate; when the lamp is closed, the driving assembly drives the cover plate to rotate reversely by a preset angle relative to the heat conducting plate, so that each second open slot of the cover plate is staggered with each corresponding first open slot, the first open slots of the heat conducting plate are shielded by the cover plate, the phenomenon that sunlight directly irradiates on the first lamp beads or the second lamp beads to cause accelerated oxidation is avoided, foreign objects are not easy to touch the first lamp beads or the second lamp beads, and the first lamp beads and the second lamp beads are not easy to damage and the working time is long.
