Abstract

The invention discloses a light emitting diode (LED) remote flood light. The light consists of a plurality of groups of LED projection devices, wherein each of groups of LED projection devices comprises an LED light source and a light-out device, the light-out device is located at the front end of the LED light source and comprises a tapered light guide cylinder, a small convex lens and a large convex lens, the small convex lens and the large convex lens are located at two ends of the light guide cylinder, and the small convex lens is close to the LED light source. Each of groups of LED projection devices is provided with projection centers which are arranged near and far, each of groups of LED projection devices is collected to the center focus of the large convex lens through the small convex lens and the light guide cylinder to the greatest extent, the light is projected, the remote projection of the light is achieved, the range is more than 300 meters, and the light has the advantages of being electricity-saving, long in service life and high in color rendering index. The device can be applied to projection lighting and high-rod light lighting of stations, wharfs, mines and yards.

Description

technical field [0001] The invention relates to an LED long-distance projecting light, in particular to a long-distance projecting light with an optical distance of 300 meters, which can be applied to projection lighting of stations, wharves, mines and freight yards and high pole lighting. Background technique [0002] At present, the variety of LED lights replacing traditional lights involves all walks of life. Due to the constraints of light distribution technology, the market has not been able to introduce LED remote floodlights with a range of 300 meters to replace such traditional floodlights. Lamps are widely used in industrial production and transportation. Therefore, it is very necessary to design LED remote floodlights. [0003] The 400w high-pressure sodium lamp is the most widely used in traditional remote floodlights. Taking this as an example to compare with the present invention, on the basis that the illumination effect of LED remote floodlights after projecti...
