Problems solved by technology

This technical solution improves the viewing angle of street lamps to a certain extent through the light distribution structure of the arched surface. Since the technical solution adopted is still to install a lens on a single LED light-emitting head, the lens only serves to focus or focus on a single LED lamp. Due to the effect of astigmatism, it is still difficult to obtain the batwing light distribution curve required for road lighting. The formed illumination area is generally rectangular, such as figure 2 As shown, but also need to install a large number of LED light-emitting heads, the cost is high

Abstract

The invention relates to an LED street lamp, which comprises an LED light source and a lampshade body used to receive the LED light source. The lampshade body comprises a shell, the shell is provided with an optical lens corresponding to the direction of the irradiation of the LED light source; after the optical lens is adopted, the rays emitted from the LED light source pass through the optical lens, are partially divided toward both sides, and are transmitted to large-angle long-distance positions, thereby realizing the evener illuminance distribution in the length direction of the road; the shell is detachably connected with the optical lens and has convenient maintenance; a reflecting shade can take full advantage of the rays more completely; a radiator discharges the heat produced bya light-emitting diode in time, which prolongs the service life.

Description

technical field [0001] The invention relates to a street lamp, in particular to an LED street lamp, which belongs to the lighting field. Background technique [0002] With the substantial improvement of semiconductor LED light efficiency and service life, semiconductor LED light sources are increasingly used in the field of indoor and outdoor lighting. It is not only easier to control the switch of the illuminated area, but also saves power consumption. It is composed of a light-transmitting mask and an LED light source. The light-transmitting mask is only a waterproof and light-transmitting accessory, and it does not have the functions of dimming and light distribution. The LED light source is made by distributing multiple LED single lamps in a plane. These LED single lamps can be electrically connected in parallel or in series, which is called an LED surface light source. The smallest light source unit that is strongly distributed and can be individually controlled is a l...
