Modularized limit emitting diode (LED) street lamp

Abstract

The invention relates to a modularized limit emitting diode (LED) street lamp. The modularized LED street lamp comprises a lamp post, an LED lamp head, a constant voltage module and a constant current module, wherein the constant voltage module and the constant current module are independently set up with each other; the LED lamp head is modularly designed and arranged on the upper part of the lamp post, and driven by an electrical power to generate a light source; the constant voltage module and the constant current module are electrically connected; and the constant voltage module is connected with an exterior supply circuit. When the modularized LED street lamp independently set by the constant voltage and constant current module works, the current enters into the constant voltage module for carrying out constant voltage, then the current processed by the constant voltage enters into the constant current module for carrying out constant current, and at last the current processed by the constant voltage and constant current drives the LED lamp to emit light.

Description

Technical field [0001] The invention relates to an LED street lamp, in particular to an LED street lamp in which a constant voltage module and a constant current module are independently arranged. Background technique [0002] As we all know, with the progress of society, people are paying more and more attention to the application of energy-saving products. Under such a social background, LED lamps have now been widely used. LED lighting products have many characteristics such as high energy saving and long life. A large number of lamps for lighting sources are used in people's lives, especially in the field of street lighting. [0003] The street lamp lighting circuit must have the functions of constant voltage and constant current, among which the constant current part can ensure the long-term use of the LED street lamp. The constant current power supply method is an ideal LED power supply method. It can avoid the current fluctuation caused by the change of the LED forward volt...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned street lamp structurally includes a lamp post, an LED light source and a street lamp circuit, wherein the lamp post is arranged on the supporting ground, the LED light source is arranged on the upper end of the lamp post, and the street lamp circuit includes a constant voltage module and a constant current module, and the street lamp circuit It is electrically connected with the LED light source and provides light-emitting power for the LED light source. However, the characteristics of the constant voltage module of such a street lamp circuit determine that the heat generated by the constant voltage module is relatively large, and the constant voltage module is fully set. In the overall street lamp circuit, the heat generated by the constant voltage module will inevitably affect the working status of other electrical components in the street lamp circuit. In extreme cases, the entire street lamp circuit will be burned due to the abnormal heating of the constant voltage module. Case

[0006] The lamp holders of existing LED street lamps all adopt the overall design method, that is, the 120W street lamps are all concentrated in one lamp holder, if there is a problem with one of the lamp beads, the entire 120W lamp holder must be replaced, which will cause serious waste of resources
