LED road lamp head

Abstract

The present invention discloses a LED street lamp holder, it includes lamp shade and LED light unit, the lamp shade includes inner surface and outer surface, the inner surface of said lamp shade is left and right symmetrical along the central line, and the half of the symmetrical inner surface consists of 4-12 flat panels, arbitrary two adjacent flat panels is located in different flat surfaces, the LED light unit is fixed on the flat panel of inner surface, the outer surface of lamp shade is equipped with heating radiator corresponding with the position of flat panel equipped with LED light unit on the inner surface. Due to the certain space angle between arbitrary two flat panels equipped with LED lamp in lamp shade, and the included angles between the flat panel and the lamp shade bottom surface are different, each LED light can irradiate different areas of road surface, thereby the use efficiency of signal LED is increased and the d lighting effect of road surface is improved. It mainly solves the shortcomings of signal angle of LED street lamp irradiation, road surface irradiation is not fully and energy-wasting and other shortcomings.

Description

technical field [0001] The invention relates to a lamp holder for a street lamp, in particular to a lamp holder for a street lamp with an excellent light distribution design using LED lighting. Background technique [0002] Traditional street light sources mainly use high-pressure sodium lamps, high-pressure mercury lamps, fluorescent lamps, etc. This type of light source is characterized by large volume, short life, poor heat dissipation performance, glare and softness, and relatively large power consumption, which has caused great damage to the power grid. The burden does not meet the requirements of a modern energy-saving society; therefore, due to the advantages of small size, long life, and low power consumption of LEDs, some street lights using LED lighting have emerged as the times require. However, the existing LED lamps for road lighting are basically formed by a simple horizontal arrangement of several LEDs. There are at least three connected LED lights embedded i...

[0002] Traditional street light sources mainly use high-pressure sodium lamps, high-pressure mercury lamps, fluorescent lamps, etc. This type of light source is characterized by large volume, short life, poor heat dissipation performance, glare and softness, and relatively large power consumption, which has caused great damage to the power grid. burden, does not meet the requirements of a modern energy-saving society; therefore, due to the advantages of small size, long life, and low power consumption of LEDs, some street lights using LED lighting have emerged as the times require

However, the existing LED lamps for road lighting are basically formed by a simple horizontal arrangement of several LEDs. There are at least three connected LED lights embedded in the concave bottom of the base, and a light-transmitting cover is equipped around the notch of the heat dissipation base. The corresponding lens is connected, and the lens fixing cover is sandwiched between the heat dissipation base and the light transmission cover. The lens fixing cover is made with lens holes corresponding to the number of LED lights, and the end of the lens is embedded through the corresponding lens holes. , LED lights are arranged horizontally on the concave bottom surface, because most of the single LED emits direct light, which has the characteristics of good light concentrating, so if multiple LEDs are simply arranged horizontally, the LEDs will illuminate at the same angle , cannot fully illuminate the road, so these lamps using LEDs cannot achieve the required light distribution for road lighting through a reasonable light distribution design. It not only affects the lighting effect, but also increases the power of the lamps, resulting in a waste of energy
