Abstract

The invention provides an LED (light emitting diode) projection lamp, which comprises a front lamp shade, a middle tube and a back tube, wherein the front lamp shade and outer periphery of the front part of the middle tube are installed through screw threads; the middle tube is of a backwards projected convex structure; a lens is arranged in the middle tube and comprises a transparent light gathering mirror surface; a reflecting mirror surface is arranged on the periphery of the transparent light gathering mirror surface; a sleeve is arranged on the periphery of the middle tube in a way of being tipsily aligned with the transparent light gathering mirror surface; the sleeve is provided with a light supplementing tube; a back lamp holder is embedded in the back side, rightly aligned with the transparent light gathering mirror surface, of the middle tube; an LED lamp board is arranged in the back lamp holder; the periphery of the back side of the middle tube and the periphery of the back side of the back lamp holder are movably installed through a long strip regulating rod. The LED projection lamp has the advantages that the short-distance linear irradiation, the short-distance scattered light illumination and the long-distance light-gathering projection can be realized; the long and short distance and short distance large range light projection can be realized; the more comprehensive illumination range is ensured.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an LED projection lamp, which belongs to the technical field of LED lamps. Background technique [0002] Flood lights make the illuminance on the specified illuminated surface higher than that of the surrounding environment; usually, it can aim in the required direction and requires a structure that is not affected by weather conditions, which is mainly used for large-scale operation sites, mines, and building outlines , stadiums, overpasses, parks and flower beds, etc. Therefore, almost all large-area lighting fixtures used outdoors can be regarded as floodlights; the beam angle of the floodlights can be wide or narrow, and the range of variation is between 5°~110° At present, more and more cities have begun to install corresponding floodlights for night lighting in blocks where high-rise buildings are concentrated, bustling commercial areas or urban landmark buildings, etc., to play the role of l...
