Problems solved by technology

[0003] In the existing LED street lamp manufacturing mode, because the LED chip must be fixed on the bracket first to prepare the LED light source, there are at least two contact surfaces between the chip and the lamp cap, and only one side of the contact surface of the light source actually touches the fixed part of the street lamp lamp cap. As a result, the heat conduction area is not enough, leading to the fact that the heat generated by the LED chip is accumulated inside the LED light source and cannot be effectively dissipated in the air. This is the main reason for the LED street light to fade

Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0011] Such as figure 1 As shown, an LED street lamp of the present invention that can effectively reduce thermal resistance includes an LED street lamp housing 1 and an LED light source 2. The LED street lamp housing 1 is provided with a concave layer 3, and the LED light source 2 is embedded in the concave layer 3. .

[0012] Change the mode of separate design of the LED light source 2 and the LED street lamp housing 1, and combine the design of the LED street lamp housing 1 and the LED light source 2 to achieve the purpose of solving heat accumulation. By reducing the contact layer in heat conduction, thereby improving heat conduction efficiency, the problem of heat conduction efficiency reduction caused by mutual contact surfaces of heat conduction layers can be effectively reduced.

Abstract

The invention discloses an LED street lamp capable of lowering heat resistance effectively. The LED street lamp comprises an LED street lamp shell and an LED light source. An indent layer is arranged on the LED street lamp shell. The LED light source is embedded into the indent layer. The LED street lamp has the advantages that the mode that the LED light source and the LED street lamp shell are designed respectively and individually is changed, the LED street lamp shell and the LED light source are combined, and therefore the problem of heat accumulation can be solved.

Description

technical field [0001] The invention relates to an LED street lamp, in particular to an LED street lamp which can effectively reduce thermal resistance. Background technique [0002] The existing LED street lamp manufacturing methods are to prepare the LED light source first, and then fix the LED light source on the prepared LED street lamp lamp cap through physical methods. There is a heat-dissipating glue between the light source and the lamp cap to increase the heat conduction function. [0003] In the existing LED street lamp manufacturing mode, because the LED chip must be fixed on the bracket first to prepare the LED light source, there are at least two contact surfaces between the chip and the lamp cap, and only one side of the contact surface of the light source actually touches the fixed part of the street lamp lamp cap. As a result, the heat conduction area is not enough, leading to the fact that the heat generated by the LED chip is accumulated inside the LED ligh...
