Embodiment 1

[0022] like figure 1 As shown, an LED street lamp that is beneficial to heat dissipation includes a lamp holder 4 and an LED illuminant 2 fixedly connected to the lamp holder 4. The LED illuminant 2 includes an LED lamp copper substrate and is fixed on one side of the LED lamp copper substrate. The LED lamp above is characterized in that it also includes a groove-shaped rear lamp cover 1 and a plurality of heat dissipation pipes 3 fixedly connected to the rear lamp cover 1, and both ends of the heat dissipation pipes 3 are fixedly connected to the rear lamp cover. 1, and the rear lamp cover 1 and the other side of the copper substrate of the LED lamp form a closed cavity, and the axial direction of the heat dissipation pipe 3 is located in the width direction of the LED street lamp.

[0023] Specifically, the plurality of cooling pipes 3 provided are the main heat dissipation parts of the LED street lamp, and the rear lamp cover 1 and the other side of the copper substrate of ...

Embodiment 2

[0025] The present embodiment is further limited on the basis of embodiment 1, as figure 1 As shown, in order to enable each LED lamp to dissipate heat evenly, the heat dissipation pipes 3 are evenly arranged in rows along the length direction of the LED street lamp.

[0026] In order to make the heat dissipation pipe 3 have a good thermal conductivity, meet the strength requirements of the LED street lamp working environment, facilitate processing, and have a heat conduction area as large as possible per unit volume, as a preference, the heat dissipation pipe 3 is a copper pipe, and the heat dissipation pipe 3 The thickness range is in the range of 0.8mm-1.5mm, and the diameter of the cooling pipe 3 is in the range of Φ6-Φ12.

[0027] In order to further enhance the heat conduction rate between the copper substrate of the LED lamp and the outer wall of the heat dissipation pipe 3, the airtight cavity formed by the rear lamp cover 1 and the other side of the copper substrate o...

Embodiment 3

[0030] The present embodiment is further limited on the basis of embodiment 1, as figure 1 As shown, the heat dissipation pipe 3 is fixedly connected to one end of the lamp holder 4 , and the other end of the lamp holder 4 is provided with a driving power supply box 5 .

[0031] In this setting, the provided drive power supply box 5 is used to set the drive power supply, and setting the drive power supply at the other end of the lamp holder 4 helps prevent the drive power supply from being affected by the heat generated by the LED lamp, and is beneficial to the service life of the drive power supply.

Abstract

The invention discloses an LED street lamp conducive to radiating. The LED street lamp comprises a lamp holder (4) and an LED luminous body (2) fixedly connected onto the lamp holder (4). The LED luminous body (2) comprises an LED lamp copper substrate and an LED lamp fixed on one side of the LED copper substrate. The LED street lamp further comprises a grooved back lamp cover (1) and a plurality of radiating tubes (3) fixedly connected onto the back lamp cover (1). Two ends of each radiating tube (3) are fixedly connected onto the back lamp cover (1) which forms a sealed cavity with the other side of the LED lamp copper substrate, and the radiating tubes (3) are axially located on the width direction of the LED street lamp. The LED street lamp is simple in structure and large in radiating area, and a circuit part of the LED street lamp is isolated with the outside and favorably prevented from being affected by outside interference.

Description

technical field [0001] The invention relates to the field of lighting devices, in particular to an LED street lamp which is beneficial to heat dissipation. Background technique [0002] After decades of technological improvement, LED light source has become the mainstream product of modern lighting with its advantages of high luminous efficiency, low power consumption, long service life, strong safety and reliability, and environmental protection. Existing LED lamps are also gradually applied to the field of street lamps. Since a single LED illuminant is generally a point light source with a small luminous angle, in order to obtain a wide range of irradiation areas, most of the illuminants of existing LED street lamps are LED illuminant groups, making The overall volume of LED street lights is large and the overall heat generation of LED street lights is large. [0003] Existing LED street lamps include a frame and LED illuminants fixed on the frame, heat dissipation pipes,...
