Modular transformer type light-emitting diode (LED) streetlamp

Abstract

The invention discloses a modular transformer type light-emitting diode (LED) streetlamp, which comprises a first bracket, a second bracket, a master bracket, a connecting plate and a plurality of LED modules. Each LED module consists of a polycarbonate (PC) cover, a waterproof adhesive tape, a light source component and a radiator, wherein the light source component is fixed on the radiator through a fastener; the waterproof adhesive tape is arranged in a groove of the PC cover; a waterproof joint and a driving power supply are fixedly arranged on the radiator; the PC cover is also fixed on the radiator through a fastener; and the radiator is connected to the first bracket through a fastener. The first and second brackets are connected to the connecting plate through angle adjusting screws, and are locked by screw caps. The second bracket is also connected to the master bracket through angle adjusting screws, and is locked by screw caps. A full-modular design is adopted, so that the streetlamp is high in consistency, stability and protection grade. By an entire flexible design, angles can be randomly adjusted, the streetlamp is convenient to replace and maintain, and light also can be supplemented. The streetlamp can be widely applied to various intelligently controlled complex ordinary roads or modern highways.

Description

technical field [0001] The invention relates to the technical field of LED road lighting, in particular to a modular transformer-type LED street lamp. Background technique [0002] LED solid-state semiconductor lighting technology is considered to be a strategic energy-saving technology in the 21st century. Many countries and cities in China, Europe and North America have developed and vigorously promoted LED road lighting technology. Compared with metal halide lamps (MH) and high pressure sodium lamps (HPS), LED street lamps have a longer life (greater than 5 times); at the same time, because LED has the characteristics of energy saving, environmental protection, long life, small size and so on. The working voltage is safe and low voltage, long service life, multi-color temperature and other advantages. In addition, LED street lights also have better controllability and light efficiency, which can realize intelligent control and save energy by as much as 50%. Another gree...

AI Technical Summary

Problems solved by technology

[0004] The fixed installation of traditional street lamps is relatively simple, and the service life is short, which requires continuous maintenance and increases construction costs. At the same time, it is difficult to realize intelligent control and secondary light distribution, which leads to low lighting efficiency and utilization.

[0005] In the existing LED street lamps, LED particles are usually assembled in a module, or the light source module and the driving circuit module are integrated in a closed lamp housing. If some light sources are damaged or the whole lamp is damaged, all must be replaced, resulting in serious resource problems. Waste; although non-module LED lamps have secondary light distribution to meet the effective irradiation range, the assembly process is relatively simple, the consistency between hundreds of light sources is relatively poor, and the one-time success rate of welding light sources is relatively low, which is not conducive to mass production; At the same time, after the lamp and the light pole are connected, in order to meet the lighting range of the lamp, the angle needs to be adjusted locally, while ordinary LED lamps do not have the function of local adjustment angle, which makes the light distribution inaccurate and the utilization rate is greatly reduced.
