LED street lamp

Abstract

The invention relates to an LED street lamp which comprises a heat dissipation cover (1) provided with a fixing handle (6), a driving power source (3) and an LED light source (2) arranged in the heatdissipation cover (1). The LED light source (2) is electrically connected with the driving power source (3), the heat dissipation cover (1) is used as a shell of the LED street lamp and externally provided with heat dissipation fins (4), and the top of the heat dissipation cover (1) is further provided with a heat dissipation column (5). When the LED street lamp is in use, heat produced by the driving power source (3) is directly transferred into air, and heat produced by the LED light source (2) is dissipated into air through the heat dissipation fins (4) and the heat dissipation column (5) on the heat dissipation cover (4).

Description

technical field [0001] The invention relates to an LED street lamp. Background technique [0002] Traditional street lighting fixtures, due to backward technology, have been difficult to meet higher and higher requirements for use, so they are gradually eliminated. The application of LED lights in the field of street lighting is gradually becoming popular. The use of LED street lights can effectively solve the low efficiency of traditional lamps. , High energy-consuming technical defects, can meet higher requirements for use, however, the LED light source chip in the LED street lamp will generate a lot of heat while emitting light efficiently, if the heat generated by the LED light source cannot be effectively dissipated to the outside world, then It will seriously affect the service life of LED street lamps and may bring potential safety hazards.

Problems solved by technology

[0002] Traditional street lighting fixtures, due to backward technology, have been difficult to meet higher and higher requirements for use, so they are gradually eliminated. The application of LED lights in the field of street lighting is gradually becoming popular. The use of LED street lights can effectively solve the low efficiency of traditional lamps. , High energy-consuming technical defects, can meet higher requirements for use, however, the LED light source chip in the LED street lamp will generate a lot of heat while emitting light efficiently, if the heat generated by the LED light source cannot be effectively dissipated to the outside world, then It will seriously affect the service life of LED street lamps and may bring potential safety hazards. Therefore, LED street lamps need to be equipped with radiators when they are in use. It is difficult for the radiator to dissipate the heat effectively, which poses a threat to the normal use of the LED street lamp. If multiple radiators are equipped in the LED lamp at the same time, it will inevitably lead to a more complicated internal structure of the LED street lamp, and increase the volume and size of the LED street lamp. Weight, but also lead to increased cost of LED street lamps

In addition, in the LED street lamps of the prior art, the drive power of the LED light source is also installed inside the lamp, and the drive power will also generate heat. If the heat dissipation is not good, it will also pose a threat to the normal use of the LED street lamp, and there is a greater safety hazard.
