Problems solved by technology

[0004] However, in the above-mentioned LED lamps disclosed in the prior art, the casing has the disadvantage that the loop space capable of accommodating the circuit board part of the lighting device is small. In order to increase the size of the loop space, if the inner shell wall and the outer shell wall size, it will cause the shell to be larger and unable to meet the needs of the shell miniaturization

Abstract

The invention relates to the technical field of lighting devices, and discloses a lighting device that ensures heat dissipation and electrical insulation, and increases loop space. The end openings are arranged; the inner shell wall is arranged in an arc shape inside the outer shell wall in the form of forming a slot space with the outer shell wall, wherein the shell wall without the inner shell wall partially forms a first groove; The device includes an arc-shaped heat dissipation wall with at least one end open and a second groove opened on the heat dissipation wall. The heat dissipation wall matches the corresponding slot space, and the second groove matches the corresponding first groove. The lighting device of the present invention realizes heat dissipation by inserting the arc-shaped heat dissipation wall into the slot space, and at the same time utilizes the grooves opened on the heat dissipation wall to increase the circuit space where the circuit substrate part of the lighting device can be arranged, or can ensure heat dissipation. At the same time, it can also reduce the volume of the casing to meet the needs of the miniaturization of the casing.

Description

technical field [0001] The invention relates to the technical field of lighting devices, in particular to a lighting device that ensures heat dissipation and electrical insulation and increases loop space. Background technique [0002] The lighting device includes a lighting circuit main substrate, a casing and a radiator. The casing and the radiator cooperate to fix the lighting circuit main substrate in the inner space of the casing. [0003] In the prior art, such as the Chinese patent application with publication number CN105874886A, an LED lamp is disclosed, such as figure 1 As shown, in order to ensure the heat dissipation and electrical insulation of the LED lamp, the casing is set to be composed of an inner casing wall (that is, the inner surface in the prior art CN105874886A) and an outer casing wall (that is, the outer surface in the prior art CN105874886A). A slot space into which the heat dissipation wall of the heat sink is inserted is formed between it and the...
