Referring to fig. 1 and 2, an embodiment of a stage light is provided.

Referring to fig. 1, the present embodiment has a lamp housing, a lens, a lamp housing 100, a bracket, an intermediate cover 140, and a bottom case 160.

The lamp housing and the lamp housing 100 clamp and fix the lens, and the lens is installed simply.

The lamp housing 100 is rotatably connected to the bracket, so that the lamp housing 100 can rotate relative to the bracket, and the irradiation angle can be adjusted.

The outer contour of the middle cover 140 is similar to the outer contour of the lamp housing 100, and the appearance is not affected.

The intermediate cover 140 is located between the lamp housing 100 and the bottom case 160, and can be used to close the bottom case 160, thereby avoiding adjusting the design of the lamp housing 100.

Referring to fig. 3, in particular, the lamp housing 100 has a first ring portion 230, a first barrel portion 180 located inside the first ring portion 230, and a first shroud 250 erected on the first ring portion 230.

The first enclosure 250 is used for supporting the lens, and the portion of the first ring 230 outside the first enclosure 250 is used for connecting the lampshade, so that the lens is fixed, and the fixation of the lens is simplified.

Wherein, the inner side of the first enclosing plate 250, the first ring part 230 and the first barrel part 180 are used for forming the lamp housing 100.

In the lamp housing 100, an LED chip and an aluminum substrate may be disposed, so that the illumination effect is satisfied, and an energy saving advantage is also provided.

Of course, a reflective structure should be disposed in the lamp housing 100 to concentrate light and improve illumination.

For wiring, a first through hole 130 may be provided at the lamp housing 100, that is, the first through hole 130 is provided at the bottom of the first barrel 180, and a wire is arranged through the first through hole 130.

In order to dissipate heat of the lamp housing 100, the heat dissipation area 120 is disposed on the back surface of the lamp housing 100, the heat dissipation area 120 is composed of a plurality of heat dissipation fins 190, and the heat dissipation fins 190 should be integrally manufactured with the first ring part 230 and the first barrel part 180, so as to reduce the manufacturing cost.

Optimally, the heat dissipation fins 190 are distributed in a central manner, so that air can smoothly flow to the outer side of the lamp housing 100 from the center of the lamp housing 100, and heat exchange is enhanced.

Referring to fig. 4, the first barrel 180 is located at the center of the lamp housing 100, the heat sink 190 is connected to the radial outer surface of the first barrel 180, and the top edge of the heat sink 190 is also at the same height as the back surface of the first barrel 180, that is, the heat sink 190 is at the same height and is connected to the radial outer side of the first barrel 180.

Thus, the intermediate cover 140 can be placed flush on the mounting surface formed by the heat sink 190 and the first tub portion 180.

Referring to fig. 4, in order to firmly fix the lamp housing 100 and the intermediate cover 140, screw holes may be provided in the back surfaces of the heat sink 190 and the first barrel 180, so that the intermediate cover 140 and the lamp housing 100 are fixed by a bolt connection.

To ensure sealing, a seal ring and a seal groove may be provided between the rear surface of the first tub 180 and the intermediate lid 140.

Of course, the intermediate cover 140 should also be provided with a second through hole 150 coaxial with the first through hole 130, without affecting the wire arrangement.

Because the thickness of the heat sink 190 is not enough to provide the threaded holes, the local part of the heat sink 190 can be formed with the reinforcing ribs 200, so that the thickness of the heat sink 190 is increased, and the arrangement of the threaded holes is facilitated.

That is, screw holes are provided in the reinforcing ribs 200 or at the joints between the reinforcing ribs 200 and the heat sink 190, thereby fixing the intermediate cover 140.

The provision of the screw holes in the ribs 200 and the heat sink 190 allows the fixing points to be close to the edge of the middle cap 140, reducing the risk of deformation of the middle cap 140.

In a simplified manner, the bottom case 160 may be provided with mounting holes 210 coaxial with the screw holes, and the mounting holes 210 may be provided with mounting bolts penetrating through the rear of the middle cover 140 to be coupled to the screw holes.

Thus, the number of screws is reduced, the cost is reduced, and the height of the whole stage lamp is also reduced.

To facilitate attachment of the bracket, two opposing fins 190 may be thickened to form the mounting portion 220 of the attachment bracket.

Therefore, the requirement of the connecting support is met, and meanwhile, the height of the radiating fins 190 is not reduced, and the radiating effect is not influenced.

Referring to fig. 3, the first ring part 230 is provided with a first groove 240 extending in a direction of a line connecting the two mounting parts 220.

Thus, the bottom of the heat sink 190 has a stepped entity forming the first groove 240, improving the torsion resistance of the mounting portion 220.

Meanwhile, the first groove 240 can be used for arranging the circuit without increasing the height of the lamp housing 100.

It will be readily appreciated that the intermediate cover 140 and the bottom housing 160, and primarily the bottom housing 160, form a control chamber 170, and that the control chamber 170 is used to house structures for controlling the light source, such as a high voltage package, a circuit board, a capacitor, a distributor, a switch, etc.

Referring to fig. 4, the bottom surface of the bottom case 160 is provided with an interface, thereby facilitating wiring.

Referring to fig. 4, the outer side of the bottom case 160 is provided with two opposite first recesses 260, thereby facilitating hand-held installation and limiting the control structure to prevent reverse installation.

Thus, the present embodiment has the following effects:

1. through setting up lamp body 100, middle lid 140 and drain pan 160 to, form two independent cavities, be lamp body 100 and control chamber 170 respectively, thereby, on the one hand, avoid the control structure of light source and light source to share a cavity, avoid increasing the volume of lamp body 100, on the other hand for radiating area 120 lug connection is on the wall of lamp body 100, makes radiating area 120 be close to the light source as far as possible, improves the radiating efficiency.

2. The middle cover 140 is further arranged, so that the heat dissipation area 120 can extend to the center of the lamp housing 100, the heat dissipation area is increased, the heat dissipation of the center of the lamp housing 100 is enhanced, and the heat dissipation efficiency is improved to the greatest extent.

3. And the intermediate cover 140 and the bottom shell 160 are arranged, so that the control cavity 170 can be independently disassembled and assembled without disassembling the lamp housing 100, the maintenance is simplified, and the probability of poor sealing of the lamp housing 100 is reduced.

4. The lamp housing 100, the middle cover 140 and the bottom case 160 are fixed together, so that they can rotate together to facilitate the adjustment of the irradiation angle.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the knowledge range of those skilled in the art.
