A circuit board is arranged in the heat dissipation frame 11 , a lamp holder 121 is optionally fixed in the lamp holder frame 12 through a bolt structure, and the circuit board is electrically connected with the lamp holder 121 . The lamp tube 2 is erected between the two lamp sockets 121, and electrical energy is supplied through the circuit board; in this embodiment, the lamp socket 121 can optionally use a VS lamp socket; the wattage of the lamp tube 2 can be optionally 1000W.

The heat dissipation frame 11 includes a heat dissipation frame main body 111 and a heat dissipation frame lower cover 112. The heat dissipation frame main body 111 is opened downward, and a circuit board is arranged inside the heat dissipation frame. The lower opening of the heat sink body 111 is closed. Specifically, a sealing groove is opened at the lower opening of the heat dissipation frame body 111 , and a sealing rubber strip 1111 is installed in the sealing groove.

The side wall of the heat dissipation frame body 111 is provided with a plurality of heat sinks distributed in a tooth shape, which increases the surface area of the heat dissipation frame body 111, thereby improving the heat dissipation capacity of the heat dissipation frame 11 and preventing the temperature of the circuit board in the heat dissipation frame 11 from being too high. , causing damage.

As shown in FIGS. 3-4 , the lower surface of the lower cover 112 of the heat dissipation frame is provided with through-hole pressure riveting studs 1121 and semicircular wire grooves 1122 . The wires in the main body 111 of the heat dissipation frame are drawn out from the end of the lower cover 112 of the heat dissipation frame, and are divided into two paths. The wire trough 1122 is electrically connected to the lamp socket 121 at the far end, which avoids the disorderly distribution of wires in the lamp, and improves the safety and aesthetics of the lamp.

The side wall of the heat sink main body 111 is provided with a plug hole, and the plug 113 is electrically connected to the circuit board through the plug hole to supply power to the whole lamp.

The reflector 3 is disposed below the heat dissipation frame 11 and between the two lamp sockets 121 through the support plate 4 . The specific structure of the reflector 3 will be described below with reference to FIG. 5 .

The reflector 3 is an arc-shaped shell structure with an opening facing downward, and includes a reflector body 31 and two connecting side plates 32 symmetrically arranged at both ends of the reflector body 31 . The lamp tube 2 is arranged in the reflector main body 31 . When the bulb emits light, the reflector 3 plays the role of reflecting light, so that the light is directed toward the opening of the reflector 3 as much as possible, so as to avoid excessive dispersion of the heat radiation of the lamp tube 2 . The connecting side plate 32 is provided with a semicircular groove, and the lamp tube 2 is erected on the lamp socket 121 through the groove.

The support plate 4 is arranged between the lower cover 112 of the heat dissipation frame and the reflector 3 . Specifically, the support plate 4 is fixedly connected to the lower cover 112 of the heat dissipation frame through riveting posts 1123 , and is connected to the reflector 3 through a clamping structure. The clamping structure includes a first clamping structure 33 and a second clamping structure 34 .

As shown in FIG. 6 , the first clamping structure 33 includes an elastic piece 331 , the upper part of the elastic piece 331 is fixedly connected with the support plate 4 by bolts, and the lower part of the elastic piece 331 is a bending structure, and is clamped with the connecting side plate 32 of the reflector 3 Since the elastic piece has a certain elasticity, the use of the elastic piece 331 for clamping can facilitate the disassembly of the reflector 3, but the reflector 3 is easy to shake in the lamp holder body 1, and the stability is poor. As shown in FIG. 7 , the second clamping structure 34 includes a clamping strip 341, the upper part of the clamping strip 341 is fixedly connected with the support plate 4 by bolts, and the lower part of the clamping strip 341 is clamped with the connecting side plate 32 of the reflector 3; The clipping of the strips 341 increases the stability of the reflector 3 and makes it less prone to shaking. However, because the clips 341 are not elastic, the disassembly and installation of the reflector 3 is inconvenient. The bolts take down the reflector 3 and the clamping structure as a whole, and the operation feasibility is poor. Therefore, in this embodiment, one end of the reflector 3 is preferably connected to the support plate 4 through the first clamping structure 33 , and the other end is connected to the support plate 4 through the second clamping structure 34 . It can be easily removed, and the reflector 3 can be placed stably in the main body 1 of the lamp holder.

In this embodiment, the connecting side plate 32 is provided with an elastic clip slot 321 corresponding to the aforementioned elastic piece 331 , and the connecting side plate 32 is further provided with a clip slot 322 corresponding to the aforementioned clip 341 .

In order to facilitate the operation of the personnel, the connecting side plate 32 of the reflector 3 is an inclined inclined plane, and the personnel can operate the clamping structure from the gap between the inclined inclined plane and the lamp socket frame 12 .

In this embodiment, since the support plate 4 and the lower cover 112 of the heat dissipation frame are arranged in parallel and spaced apart from each other through the rivets 1123, the support plate 4 not only serves the purpose of connecting the lamp frame main body 1 and the reflector 3, but also serves as an isolation The effect of the heat radiation of the lamp tube 2 further improves the heat dissipation effect of the whole lamp.

In this embodiment, the circuit board and the lamp holder body 1 with heat dissipation function are integrated into one body, which replaces the ballast structure in the traditional lamp, which can greatly reduce the volume of the lamp and reduce the overall height of the lamp; The frame lower cover 112 is fixed by the riveting column 1123, so by reducing the height of the riveting column 1123, the distance between the support plate 4 and the cooling frame lower cover 112 can be shortened, and the height of the whole lamp can be further compressed.
