[0002] An electronic transformer is an electronic device that converts the alternating voltage of the mains into direct current and then forms a high-frequency alternating voltage output through semiconductor switching devices, electronic components and high-frequency transformer windings. It is also an AC-DC-AC inverter circuit described in electronics theory.

[0003] The electronic transformer for lighting lamps is often not convenient for heat dissipation. Since the lighting lamp itself generates heat, the electronic transformer will also generate heat during long-term operation, making it difficult for the electronic transformer to dissipate heat. Content of the Utility Model

[0004] The purpose of the utility model is to provide an electronic transformer for lighting lamps to solve the problem that the existing electronic transformers are often not convenient for heat dissipation.

Concave-shaped frames are respectively fixed on both sides of the bottom of the electronic transformer body. An installation plate is provided below the concave-shaped frames. Fixed seats are respectively fixed on both sides of the installation plate. Convex-shaped grooves are provided on the fixed seats. Convex-shaped rods are slidably connected in the convex-shaped grooves. The bottoms of the opposite sides of the two convex-shaped rods can be respectively inserted into the recesses of the corresponding concave-shaped frames. A diversion block is fixed in the middle of the installation plate.

[0006] The electronic transformer for lighting lamps provided by the utility model further has the following technical features:

[0007] Further, the shape of the diversion block is a quadrangular pyramid.

[0008] Further, one side of the convex-shaped rod is connected to the corresponding fixed seat through a spring, and the lower side of the convex-shaped rod can contact the concave-shaped frame.

[0009] Further, inclined surfaces are respectively provided on the opposite sides of the two convex-shaped rods.

[0010] Further, a heat-conducting silica gel sheet is provided on the upper side of the electronic transformer body. Four corners on the upper side of the electronic transformer body are respectively connected with support feet through bolts. A radiator is fixed on the four support feet. The lower side of the radiator contacts the heat-conducting silica gel sheet.

[0011] Further, grooves are respectively provided on both sides of the installation plate.

[0012] The utility model has the following beneficial effects: By fixing the mounting plate to an external structure and inserting the opposite ends of two convex rods into the depressions of corresponding concave frames respectively, it is convenient to limit and fix the electronic transformer body. The combined use of the heat dissipation holes and the strip holes plays a role in heat dissipation, and the flow guiding block plays a role in guiding the flow.

[0018] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.

[0019] As Figures 1 to 5 shown in the embodiment of the electronic transformer for a lighting lamp of the present utility model, the electronic transformer for a lighting lamp includes an electronic transformer body 1. Heat dissipation holes 2 are formed in the side surface of the electronic transformer body 1, strip holes 3 are formed in the bottom of the electronic transformer body 1, concave frames 4 are respectively fixed on both sides of the bottom of the electronic transformer body 1, a mounting plate 5 is arranged below the concave frames 4, fixing seats 6 are respectively fixed on both sides of the mounting plate 5, convex grooves are formed in the fixing seats 6, and convex rods 7 are slidably connected in the convex grooves. The bottoms of the opposite sides of the two convex rods 7 can be respectively inserted into the depressions of the corresponding concave frames 4. A flow guiding block 8 is fixed in the middle of the mounting plate 5. By fixing the mounting plate 5 to an external structure and inserting the opposite ends of the two convex rods 7 into the depressions of the corresponding concave frames 4 respectively, it is convenient to limit and fix the electronic transformer body 1. The combined use of the heat dissipation holes 2 and the strip holes 3 plays a role in heat dissipation, and the flow guiding block 8 plays a role in guiding the flow. When air flows through the gap between the electronic transformer body 1 and the mounting plate 5, the air can enter the interior of the electronic transformer body 1 through the flow guiding block 8, thus achieving the purpose of facilitating heat dissipation.

[0020] In an embodiment of the present application, preferably, the shape of the flow guide block 8 is a quadrangular pyramid, so that the air flow can gather at the top of the quadrangular pyramid, facilitating entry into the electronic transformer body 1.

[0021] In an embodiment of the present application, preferably, one side of the convex rod 7 is connected to the corresponding fixed seat 6 via a spring, and the lower side of the convex rod 7 can contact the concave frame 4, enabling the convex rod 7 to limit and fix the concave frame 4 and the electronic transformer body 1 under the action of the spring.

[0022] In an embodiment of the present application, preferably, inclined surfaces are respectively provided on the opposite sides of the two convex rods 7. When installing the transformer body 1, by pressing down on the transformer body 1 to install it, the concave frame 4 contacts the inclined surfaces on the convex rods 7, thereby driving the convex rods 7 to move, facilitating the installation of the transformer body 1. When the transformer body 1 is installed in place, the convex rods 7 can reset under the action of the spring.

[0023] In an embodiment of the present application, preferably, a heat-conducting silica gel sheet 9 is provided on the upper side of the electronic transformer body 1. Four corners on the upper side of the electronic transformer body 1 are respectively connected to support feet 10 by bolts, and a radiator 11 is fixed on the four support feet 10. The lower side of the radiator 11 contacts the heat-conducting silica gel sheet 9. The heat-conducting silica gel sheet 9 is a heat-conducting medium material synthesized by a special process with silica as the base material and adding various auxiliary materials such as metal oxides. Through the cooperative setting between the radiator 11 and the heat-conducting silica gel sheet 9, further heat dissipation can be achieved.

[0024] In an embodiment of the present application, preferably, grooves are respectively formed on both sides of the mounting plate 5. By using bolts to clamp at the grooves on both sides of the mounting plate 5 and tightening the bolts with an external structure, the position of the mounting plate 5 can be fixed.

[0025] When the present utility model is in use, by using bolts to clamp at the grooves on both sides of the mounting plate 5 and tightening the bolts with an external structure, the position of the mounting plate 5 can be fixed. By pressing down on the transformer body 1 to install it, the concave frame 4 contacts the inclined surfaces on the convex rods 7, thereby driving the convex rods 7 to move, facilitating the installation of the transformer body 1. When the transformer body 1 is installed in place, the convex rods 7 can reset under the action of the spring. The opposite ends of the two convex rods 7 are respectively inserted into the recesses of the corresponding concave frames 4. The combined use of the heat dissipation holes 2 and the strip holes 3 plays a role in heat dissipation. The flow guide block 8 plays a role in guiding the flow. When the air flow flows through the gap between the electronic transformer body 1 and the mounting plate 5, the air flow can enter the electronic transformer body 1 through the flow guide block 8, thereby achieving the purpose of facilitating heat dissipation. Through the cooperative setting between the radiator 11 and the heat-conducting silica gel sheet 9, further heat dissipation can be achieved.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
