Description

Technical Field

[0001] This utility model belongs to the field of lighting technology, and more specifically, relates to a lighting fixture with high-efficiency heat dissipation. Background Technology

[0002] LED lighting is a type of lighting device that uses a light-emitting diode (LED) as its core light-emitting element. It emits visible light in the form of photons by releasing energy through the recombination of electrons and holes in semiconductor materials. It is the third generation of lighting technology after incandescent and fluorescent lamps, and due to its high efficiency, energy saving, and environmental friendliness, it has become the mainstream choice in the modern lighting field.

[0003] However, the current electro-optical conversion efficiency of LED light sources is only about 20%-40%, and the remaining energy is dissipated in the form of heat. If this heat cannot be dissipated in time, it will cause the LED junction temperature to rise, which will not only lead to luminous efficiency decay and seriously affect the lighting quality, but also accelerate the aging of LED chips and packaging materials, reducing the life of the lamp and potentially causing circuit failure, lamp body deformation, or even fire risk. Utility Model Content

[0004] In order to solve the problems existing in the prior art, this utility model aims to provide a lighting fixture with high-efficiency heat dissipation, so as to improve the efficiency of heat conduction and dissipation and effectively reduce the junction temperature of LEDs.

[0006] A high-efficiency heat dissipation lighting fixture includes a base for connection to a ceiling, a mounting base with LED light sources, a lampshade, and a light guide plate. The base is detachably connected to the upper end of the mounting base, and the lampshade is detachably connected to the lower end of the mounting base. The light guide plate is disposed on the inner bottom surface of the lampshade, and the outer side of the lampshade is provided with a ring of evenly distributed fins A, forming a three-dimensional heat dissipation array structure. The heat dissipation area is increased by the fins A, thereby improving the overall heat dissipation efficiency of the lighting fixture.

[0007] Furthermore, both the lampshade and the fin A are made of aluminum alloy and are integrally formed together.

[0008] Furthermore, a groove is formed on the outer side of the lampshade, and the fin A is disposed in the groove.

[0009] Furthermore, the fixing base includes upper and lower connecting parts, with the lower connecting part detachably disposed on the upper connecting part; wherein, the base is detachably connected to the upper end of the upper connecting part, and the lampshade is detachably connected to the lower end of the lower connecting part.

[0010] Furthermore, a fin B is provided between the upper and lower connecting parts.

[0011] Furthermore, both the lower connecting part and the fin B are made of aluminum alloy, and the two are integrally formed.

[0012] Furthermore, the upper connecting part and the base are snapped together; the lower connecting part is locked onto the lampshade by a corresponding locking bolt.

[0013] Furthermore, the upper end of the upper connecting part is provided with a mounting groove into which the base sinks.

[0014] The beneficial effects of this utility model are as follows: By setting fins in the lampshade and the mounting base for arranging the LED light source, this utility model effectively increases the heat dissipation area, improves the overall heat dissipation efficiency of the lamp, and effectively reduces the LED junction temperature, thereby avoiding problems such as luminous efficacy decay, lamp life reduction, circuit failure, lamp body deformation, and even fire risk caused by high temperature; Secondly, in this application, the mounting base has a heat dissipation channel, and the fins are set in the heat dissipation channel, ensuring that the mounting base can quickly dissipate heat during the lamp's use, while also ensuring that heat is quickly dissipated.
