Modularization LED street lamp with adjustable angle

Abstract

The invention discloses a modularization LED street lamp with adjustable angle. The street lamp comprises a lamp body, an LED module, a reflecting bowl, a sealing ring, a diffuser, a constant current driver and a power supply, wherein a plurality of module mounting surfaces with different angles are arranged in the diffuser; the reflecting bowl and the LED module which are formed into a whole are arranged on the diffuser; and the sealing ring is embedded inside the periphery of the diffuser. The street lamp is characterized in that the lamp body forms a rotary spindle component in a mode of combining stretching and casting for adjusting an elevation angle of the lamp; and two groups of radiating fins of the lamp body are connected and fixed through rotation of the rotary spindle component, and are movably hinged with a round rod stretched by the fins through a semi-open slot stretched by a main shaft rod. Light with different light-emitting angles can be generated in a mode of adjusting a reasonable combination of angles and slants of an internal light source, so that light emitted by the light source can be more effectively utilized, while excellent radiation effect is considered, and the LED street lamp can accord with the requirement on illuminance and uniformity of the street.

Description

technical field [0001] The invention relates to a street lamp for lighting, in particular to an LED street lamp using a high-power and high-brightness light-emitting diode as a lighting source, and belongs to the technical field of semiconductor application lighting. Background technique [0002] Existing numerous LED urban lighting street lamps use low-power LED arrays as illuminants to solve the problem of heat dissipation. However, the light decay of low-power LEDs is strong, and the number of LEDs used is large, so the installation cost is relatively high. Urban lighting LED street lamps are bound to adopt high-power LED development trends, and a few street lamp products that use high-power LEDs as illuminants do not solve the problem of heat dissipation of LEDs when the power reaches a certain level; LED astigmatism and spotlight control Problems: the illuminance range, type, and balance of illuminance of street lamps on the road surface; the photoelectric conversion e...

Problems solved by technology

The light distribution curve of the conventional light source in the current traffic and road lighting traditional light source is a wide-angle circular normal distribution, and most of the current road lighting designs use single-side lighting, which will cause local light sources to be wasted in the surrounding lighting; in addition, according to the current According to traffic lighting design standards, the distance between street lights in the direction of the road is generally three times the height of the lights. Due to the defects of the light distribution curve of conventional light sources, some light sources cannot illuminate dark areas.

This not only causes a waste of energy, but also brings great safety hazards to driving at night.
