LED road lamp head

Abstract

A lamp adapter of LED road lamp, comprising a lampshade (1) and LED groups (3). The lampshade (1) comprises an internal surface and an external surface, the shape of the internal surface is eudipleural about a centerline (5), a half of the symmetrical internal surface is composed of 4-12 flat plates (13), and any two adjacent flat plates (13) are provided on different planes. The LED groups (3) are mounted on the flat plates (13), heat radiators (4) are provided on the external surface of the lampshade (1), and the positions of the heat radiators (4) correspond to the positions of the flat plates (13) having LED groups (3) mounted thereon. Any two flat plates (13) having LED groups (3) mounted thereon have a certain space angle between them, and there are different included angles between respective the flat plates (13) and a bottom surface of the lampshade (1).

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
