LED street lamp

Abstract

The invention relates to an LED street lamp, which comprises two groups of LED components. The LED components comprise light source components and radiators, and an angle adjusting device is arranged between the two groups of LED components. During mounting, the radiators can be rotated around a rotating shaft to a set position according to requirement, and then a fixed seat and a connection plate are connected together through a connection block, so the rotators can be rotated to different angles by changing the engagement position of the connection block and the connection plate so that an LED light source rotates to different angles to meet the requirements of different irradiation angles and irradiation ranges so as to achieve the best illumination effect; the irradiation angle and the irradiation range of the LED light source are convenient and quick to adjust; and the adjusting device has a simple structure and wide application range, large modification for a production process according to different road conditions is not needed, the LED street lamp is easy to be produced in batch, and the production cost is greatly lowered.

Description

technical field [0001] The invention relates to a lighting facility, in particular to an LED street lamp whose irradiation angle can be adjusted. Background technique [0002] It has been more than 30 years since the first batch of LEDs began to enter the market in 1986. Compared with traditional lighting, LED lighting has the advantages of less heat generated, higher luminous efficiency, and long service life, and has been widely used. . At present, the main application areas of LED include large-screen color display, lighting fixtures, lasers, multimedia imaging, LED background light source, detectors, traffic lights, instrumentation, optical fiber communication, satellite communication, marine communication, and graphic recognition. [0003] LED is an all-solid cold light source, small in size, light in weight, strong in structure, low in operating voltage, and long in service life. According to the usual definition of light efficiency, the luminous efficiency of LED is ...

Problems solved by technology

Therefore, in different road conditions, it is necessary to make different adjustments to the structure of the street lamp pole during the production stage, that is to say, for street lamps with different road conditions, the production process also needs to be adjusted, which increases production costs and is not conducive to mass production and Subsequent installation and debugging, during installation, the irradiation angle and range of LED street lights cannot be adjusted according to the actual situation such as the height of the light poles and the distance between the light poles, so that the LED street lights cannot achieve the best lighting effect
