Embodiment Construction

[0025] In order to enable those skilled in the art to better understand the present invention, it is described in detail with accompanying drawings, please refer to Figure 1-2A As shown, the present invention discloses an LED street lamp, comprising a rear shell 1, a front shell 2, a fixed light pole seat 3, and a transparent lampshade 4, wherein:

[0026] The transformer 5 is fixed on the outer surface of the rear case 1 , and the LED lamp board 6 is fixedly arranged on the front case 2 .

[0027] A plurality of cooling fins 11 are arranged on the outer surface of the rear case 1, and a plurality of arc-shaped grooves 12 are arranged on the inner surface of the rear case 1. The section of the arc-shaped groove 12 is arc-shaped, and its length is the same as that The shells 1 are equal in length, and the surface where the front shell 2 and the rear shell 1 are combined, that is, the inner surface of the front shell 2 is provided with arc-shaped grooves 21 equal in number to t...

Abstract

The invention discloses an LED street lamp, comprising a front shell, a rear shell, a lamp post fixing base, a transparent lamp cover, a voltage transformer and an LED lamp panel, wherein, the voltage transformer is fixedly arranged on the rear shell and the LED lamp panel is connected with the front shell; two or more radiating fins are arranged on the external surface of the rear shell, at least one groove is arranged on the internal surface of the front case, and two or more radiating fins are arranged in the groove; the arrangement of the radiating fins is convenient for transferring the heat of the LED lamp panel into the air, so as to radiate the heat of LED in time; therefore, the radiation of the LED street lamp is guaranteed, the service life of the LED street lamp is prolonged, and the light decay decreases to the degree that the light decay can even be neglected so that the brightness of the LED street lamp is warranted.

Description

technical field [0001] The invention relates to a street lamp, in particular to a street lamp using LED as a light source. Background technique [0002] Existing LED street lamps use the principle of aluminum alloy conduction heat dissipation to have the following disadvantages: when metal copper or aluminum alloy is connected to the LED lamp board and the ballast, the heat dissipation of the LED and the ballast can reduce the temperature of the LED lamp board and the ballast. When the number of LEDs exceeds 32, this method cannot effectively dissipate the temperature of the LEDs and ballasts into the air, thus causing the temperature in the overall light box to reach above 70 degrees Celsius. The LED street lights are integrated and sealed on the outside. When the temperature rises, the LED decays quickly until it goes out and cannot be used. Contents of the invention [0003] The purpose of the present invention is to provide an LED street lamp, which can solve the heat...
