Problems solved by technology

However, relying solely on the aluminum substrate cannot provide sufficient heat dissipation, and covering the heat dissipation aluminum body will also cause a decrease in heat dissipation efficiency, which will lead to heat accumulation and temperature rise inside the LED lamp, and the accumulation of heat will affect the performance of the LED lamp and its power supply. Work normally, even cause damage to LED lights

Embodiment Construction

[0025] Such as figure 1 As shown, in the first embodiment of the present invention, the LED lamp is generally represented by reference numeral 1, wherein the LED lamp bead 2 of the LED lamp 1 is installed on the PCB board 3, and the PCB board 3 is connected to the heat dissipation slice 4 on. The heat sink is made of thermally conductive material, such as aluminum, aluminum alloy, etc. In this way, the heat generated by the LED lamp bead 2 is conducted to the heat sink 4 through the PCB board 3 to dissipate heat.

[0026] The LED lamp 1 also has a semi-cylindrical lampshade 5 and a housing 6, wherein the lampshade 5 is made of a transparent or translucent material, so that the light emitted by the LED lamp bead 2 can pass through the lampshade, and the housing 6 is then made of insulating material, for example made of plastic material etc. The lampshade 5 and housing 6 are interconnected in a manner known in the art so as to form a cylindrical chamber. For example, the lam...

Abstract

The invention relates to an LED lamp, which has a lampshade and a casing, the lampshade and the casing are connected to each other to define a cavity, and the cooling fins are connected to the inner side of the lampshade or the casing, so that the cooling fins divide the cavity into a cooling cavity and a housing. A light-emitting chamber of a PCB board installed with LED lamp beads, wherein the PCB board is connected to the base plate of the heat sink, and the base plate is configured to have different heat dissipation at different parts of the base plate. The invention also relates to a heat sink and a modular housing for the LED lamp.

Description

technical field [0001] The invention relates to an LED lamp. Background technique [0002] As a new type of light source, LED lamp has the advantages of high luminous efficiency, energy saving, environmental protection, etc., so it is more and more widely used in lighting, decoration and other fields. Chinese utility model patent CN 201851928U discloses an LED lamp, which includes LED lamp beads installed on a printed circuit board (PCB board), the PCB board is installed on an aluminum substrate, and the LED lamp beads are made of a transparent or semi Covered with a transparent lampshade. The LED lamp also includes a heat dissipation aluminum body, and the insulated power supply circuit board is arranged in the heat dissipation aluminum body. The aluminum substrate and the heat dissipation aluminum body are connected to each other or formed into one body. In this way, the heat generated by the LED lamp beads is transmitted to the heat dissipation aluminum body through th...
