LED spotlight

Abstract

The invention provides an LED spotlight, and belongs to the technical field of LED lamps. The LED spotlight solves the problem that the existing LED spotlight is poor in heat dissipation performance.The LED spotlight comprises a cylindrical shell, a reflecting shade is fixed in the shell body, a substrate is fixed at the upper end of the reflecting shade, the substrate is provided with an LED lamp bead, two pressure arms are hinged at the upper end edge of the shell, a plurality of transverse radiating fins are horizontally fixed on the substrate, a plurality of connecting columns are fixed on the transverse radiating fins, the plurality of connecting columns are respectively arranged at the edge of the transverse radiating fins along the circumferential direction, vertical radiating finsare rotatably connected on the connecting columns, the vertical radiating fins are in an arc shape, and when the vertical radiating fins swing inwards, the concave surfaces of the vertical radiatingfins are attached to the outer edges of the transverse radiating fins, and the substrate is also provided with a transmission piece which can enable the vertical radiating fins to swing outwards whenthe pressure arms swing downwards. The LED spotlight has better heat dissipation performance and ensures the service life.

Description

technical field [0001] The invention belongs to the technical field of LED lamps and relates to an LED spotlight. Background technique [0002] Spotlights can be installed around the suspended ceiling or on the upper part of the furniture, inside the wall, in the dado or skirting line, and the light is directly irradiated on the household utensils that need to be emphasized, so as to highlight the subjective aesthetic effect and achieve a prominent focus, unique environment, rich layers, and atmosphere. Strong, colorful artistic effects, soft spotlights, elegant and luxurious, can not only play a leading role in the overall lighting, but also can be partially illuminated to enhance the atmosphere. [0003] As disclosed in the patent document (Application No.: 201820210830.0), a spotlight includes a base, and there is a storage cavity inside the base, a driving power is placed in the storage cavity, and a heat dissipation panel connected to the base , the aluminum-based circ...

Problems solved by technology

[0003] As disclosed in the patent document (Application No.: 201820210830.0), a spotlight includes a base, and there is a storage cavity inside the base, a driving power is placed in the storage cavity, and a heat dissipation panel connected to the base , the aluminum-based circuit board installed on the heat dissipation panel, the front frame connected to the heat dissipation panel, the panel installed inside the front frame, and the lugs installed on the side of the front frame, the panel installed inside the front frame and the The height of the front frame is even, and an insulating ring is provided on the part where the front frame is in contact with the heat dissipation panel. The inside of the insulating ring is provided with a first thread, and the edge of the heat dissipation panel is correspondingly provided with a second screw thread. Two threads, the base is provided with a heat dissipation panel fixing column, and the heat dissipation panel is correspondingly provided with a fixed through hole. Since the spotlight will generate a lot of heat during work, a heat dissipation plate is required for heat dissipation. However, the spotlight is installed when it is installed. It needs to be inserted into the hole that has been opened in the ceiling. The hole matches the outer diameter of the spotlight housing, so the radial dimension of the heat sink needs to be smaller than the diameter of the hole, which will limit the heat dissipation performance of the heat sink and affect the performance of the spotlight.
