Problems solved by technology

Street lamps are widely used in various places that need lighting. With the development of cities and the construction of modern new countryside, more and more street lamps are planned for main streets. However, the existing street lamps have complex circuits, high manufacturing costs, and poor applicability. Shortcomings, therefore, in order to solve the above problems, an energy-saving controllable power supply for street lamps is needed

Abstract

The invention discloses an energy-saving and controllable power supply for street lamps, which comprises a radar control module, a light control module, a step-up constant current module and a light-emitting part. The output end of the radar control module is connected with the input end of the step-up constant current module. The output end of the module is connected to the input end of the boost constant current module, and the output end of the boost constant current module is connected to the light emitting element. The dynamic light emitting element control circuit formed by the combination of the radar control module and the light control module can be used to control the light emitting element. Brightness, the combination of the two and the boost constant current module can realize the function of stably controlling the working state of the light-emitting element; in general, the present invention has the advantages of simple circuit, low manufacturing cost and good applicability.

Description

technical field [0001] The invention relates to the technical field of road traffic lighting, in particular to an energy-saving controllable power supply for street lamps. Background technique [0002] Street lamps refer to lamps that provide lighting functions for roads, and generally refer to lamps within the range of road lighting in traffic lighting. Street lamps are widely used in various places that need lighting. With the development of cities and the construction of modern new countryside, more and more street lamps are planned for main streets. However, the existing street lamps have complex circuits, high manufacturing costs, and poor applicability. Shortcomings, therefore, in order to solve the above problems, an energy-saving controllable power supply for street lamps is needed. Contents of the invention [0003] The main purpose of the present invention is to provide an energy-saving controllable power supply for street lamps with simple circuit, low manufact...
