Lampshade provided with light distribution lens and LED street lamp

Abstract

A lampshade provided with light distribution lenses comprises a lampshade body and the light distribution lenses, wherein, the main part of the lampshade body takes on a long strip shape and is evenly distributed with a plurality of light distribution lenses. An LED street lamp with high power is formed by connecting a plurality of LED light sources to a driving power in series and parallel by a printed circuit. A light fitting consists of the lampshade provided with the light distribution lenses, the LED light sources, a radiator provided with a circulating channel, the driving power, a lamp arm clamping device and other fittings, wherein, the radiator, a driving power pack and the lamp arm clamping device integrally form the main body of the light fitting by aluminium alloy, the LED light sources are fixedly connected on the lower end surface of a heat transmission base plate of the radiator, an LED light source series which is formed by connecting the LED light sources in series by the printed circuit and an LED light source array unit that is formed by connecting the LED light sources in parallel are respectively connected at a positive pole and a negative pole of an output end of a power supply, each group of LED light sources which are connected in series are sealed by the lampshade provided with the light distribution lenses, and the center of each lens on the lampshade is installed correspondingly to the LED light source. As the LED street lamp adopts the lampshade provided with the light distribution lenses, the structure of the light fitting is simplified, the manufacturing cost is reduced, the light loss of the light fitting is decreased, and the light-emitting efficiency of the light fitting is improved. The radiator provided with the circulating channel can strengthen air convection, improves the effect of heat dissipation, and can reduce the volume of the radiator under the same power, thus saving raw materials and reducing the manufacturing cost.

Description

technical field [0001] The invention relates to a lighting fixture, specifically a lampshade with a light distribution lens and an LED street lamp. Background technique [0002] The outbreak of the global energy crisis has increasingly highlighted the importance of energy saving and consumption reduction. As an important part of energy consumption that cannot be ignored, lighting electricity has been widely valued by people, and the high efficiency and energy saving of LED as a new generation of lighting sources is also gradually It is recognized that the LED lighting industry is booming, but the "noble" nature of LED lamps on the market currently makes it difficult to popularize and apply them. The specific technical defects include complex structure of lamps, low light output efficiency, large volume of lamps, especially radiators, and energy consumption. A series of technical problems such as the high cost of raw materials. Contents of the invention [0003] In order t...
