Detailed Description

Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

The utility model relates to a radiating structure of a projection lamp, which comprises a plurality of radiating fins 100. As shown in fig. 1, each fin 100 is disposed in a vertical state with the plate surface facing left and right, and the fins 100 are connected at intervals in the lateral direction from left to right.

As shown in fig. 2 and 3, the heat sink 100 is provided with a connection member 200 near the periphery thereof. In the present embodiment, the connection members 200 are provided at positions near both front and rear sides of the fin 100 in the illustrated direction. The connection member 200 includes two connection tabs 210, a connection socket 220, and a reinforcement bar 230. Both tabs 210 of the same set extend laterally from the heat sink 100 in the same orientation. In the present embodiment, each connecting piece 210 extends on the heat sink 100 to the left perpendicular to the plate surface of the connecting piece 210. Reinforcing bars 230 extend from the plate surface of the heat sink 100, and the reinforcing bars 230 are connected between two connecting pieces 210 of the same group. The connection sockets 220 are arranged in a position and number to fit the connection pads 210. When the heat sink 100 is installed, the heat sinks 100 are sequentially arranged from left to right, and the ends 211 of the connecting pieces 210 on the heat sink 100 positioned on the right side are inserted into the connecting sockets 220 on the heat sink 100 positioned on the left side towards the left in the adjacent two heat sinks 100. The two connection pieces 210 in the same group effectively increase the structural strength of the connection piece 210 on the heat sink 100 under the supporting action of the reinforcing strip 230, and improve the stability of the connection piece 210. The heat sinks 100 are connected through the connecting pieces 210, and the connecting pieces 210 are close to the peripheral positions of the connecting plates, so that the situation that the peripheral edges of two adjacent heat sinks 100 are relatively close to or far away from each other can be effectively avoided, namely, the structural stability of the heat sink formed by the installation of the connecting members 200 of the heat sinks 100 is ensured.

In some embodiments, the two connection pieces 210 of the same group are disposed parallel to each other, or, as shown in fig. 2, the two connection pieces 210 of the same group are not parallel to each other, and spatially intersect the space plane where the two connection pieces 210 of the same group are located. The reinforcing bar 230 extends from one connecting piece 210 to the other connecting piece 210 in a curve shape, which effectively increases the structural strength of the reinforcing bar 230 itself. The heat sink 100 is a metal sheet. In some embodiments, the connection member 200 is die cut on the heat sink 100. As shown in fig. 2, two connection sockets 220 are punched on one connection member 200, and the connection sockets 220 may have a rectangular opening shape. The connection piece 210 is die-cut in a U shape, and the end 211 of the connection piece 210 is die-cut in an L shape. After the connecting piece 210 and the reinforcing strip 230 are punched to have corresponding shapes, the connecting piece 210 and the reinforcing strip 230 are bent relative to the plate surface of the heat sink 100, and the connecting piece 210 and the reinforcing strip 230 are integrally formed on the heat sink 100. After bending, the corners of the reinforcement bars 230 extend in an arc from one connecting piece 210 to the other connecting piece 210. The die-cut and bent connection piece 210 is vertical or nearly vertical to the plate surface of the heat sink 100 in space. The reinforcing strips 230 formed by punching and bending have high structural strength, and can effectively reduce the deflection amplitude of the connecting sheet 210 relative to the plate surface of the radiating fin 100. After the heat sinks 100 are connected, the connection piece 210 stably and effectively supports the heat sinks 100, so as to ensure the structural stability of the periphery of the formed heat sink.

The heat sink 100 has a bottom edge 101 and side edges 102. In this embodiment, as shown in fig. 2, the bottom edge 101 extends horizontally in the front-rear direction, and the side edge 102 extends obliquely in the vertical direction. Of the two tabs 210 in the same set, one tab 210 is adjacent and parallel to the bottom edge 101 and the other tab 210 is adjacent and parallel to the side edge 102. The two tabs 210 of the same set effectively support the heat sink 100 near the side edges 102 and 101, respectively, against deformation.

In some embodiments, as shown in fig. 1 and 3, baffles 300 are installed at both left and right sides of the heat sink formed by the heat sink 100. The baffles 300 on both sides are respectively connected to the heat sink 100 on the left and right outermost sides. As shown in fig. 3, a stopper 310 is provided on the baffle 300. The stopper 310 extends on the baffle 300 toward the heat sink 100. The stopper 310 may be formed by punching and bending the baffle 300. The stopper 310 is disposed near the periphery of the baffle 300. When the baffle 300 is connected with the heat sink 100, the limiting piece 310 abuts against the plate surface of the heat sink 100, and the limiting piece 310 supports between the periphery near the baffle 300 and the periphery of the heat sink 100, so as to avoid deformation of the periphery of the baffle 300 relative to the periphery of the baffle 300.

In some embodiments, a cover plate 400 is installed at the bottom of the heat sink formed by the heat sink 100. As shown in fig. 4, 5 and 6, the cover 400 is provided with flanges 410 at both front and rear sides. The flange 410 is provided with a plurality of notches 411, and the notches 411 are uniformly distributed along the length direction of the flange 410. The relative positions of the notches 411 are adapted to the relative positions of the fins 100. The cover plate 400 covers the bottom of the radiator, the bottom edges 101 of the cooling fins 100 are correspondingly clamped in the gaps 411, and the bottoms of the cooling fins 100 are fixed and positioned by the gaps 411, so that the structural stability of the bottom of the radiator is further improved. Wherein the notch 411 is configured as a V-shape, the V-shaped notch 411 facilitates rapid guiding of the bottom edge 101 of the heat sink 100 into the notch 411. As shown in fig. 6, the left and right sides of the cover plate 400 are provided with protruding mounting heads 420. The mounting head 420 is fixedly connected with the side edge of the baffle 300 by means of screws or welding.

As shown in fig. 1 and 7, the upper edge 103 of the fin 100 is bent horizontally. After the heat sinks 100 are connected, the upper edge 103 of each heat sink 100 forms a heat dissipation plane 110. The heat dissipation plane 110 mounts the light source assembly 500 thereon. Heat generated during operation of the light source assembly 500 is transferred to each heat sink 100 through the heat dissipation plane 110, and then dissipated through the heat sink 100 to dissipate heat.
