A led floodlight with adjustable light center distance

Abstract

The invention discloses an LED floodlight with adjustable optical center distance, which comprises a floodlight main body, a base plate and a fixing ring, and the floodlight main body includes a lens adjustment cylinder, a lens frame, a locking screw, a middle block, a heat pipe, The first fin, the second fin, the heat dissipation frame and the protective shell, the middle block is a cylindrical structure made of copper, and a group of end surfaces of the middle block are attached and fixed with several groups of lamps distributed in a rectangular array. Beads, two sets of threads are respectively opened on the two ends of the outer circle of the middle block, five sets of heat pipes are inserted on the surface of the middle block facing away from the lamp post, the five sets of heat pipes are parallel to each other, and the five sets of heat pipes The first fins are sleeved and fixed at both ends, the second fins are sleeved and fixed on the heat pipe between the first fins on both sides, the bottom plate is a circular plate-like structure placed horizontally, and a vertical The vertical lower column on the base plate. The LED floodlight with adjustable optical center distance can adjust the optical center distance of the floodlight according to needs, and is suitable for popularization and use.

Description

technical field [0001] The invention belongs to the technical field of LED lamps, and in particular relates to an LED projection lamp with adjustable light center distance. Background technique [0002] LED is a solid-state semiconductor device that can convert electrical energy into visible light, and it can directly convert electricity into light. The heart of LED is the wafer of a semiconductor, and one end of wafer is attached on a bracket, and one end is negative pole, and the other end connects the positive pole of power supply, and whole wafer is encapsulated by epoxy resin. [0003] Existing LED floodlights mostly use single-group lenses or non-adjustable reflective lenses to condense light. The problem is that when the distance of the illuminated object changes, the size of the emitted light spot cannot be adjusted within a suitable range. The result is that the spot of the object that needs to be illuminated by concentrated light is too large to affect the observa...

[0003] Existing LED floodlights mostly use single-group lenses or non-adjustable reflective lenses to condense light. The problem is that when the distance of the illuminated object changes, the size of the emitted light spot cannot be adjusted within a suitable range. The result is that the spot of the object that needs to be illuminated by concentrated light is too large to affect the observation of details, and the spot that needs to be illuminated in a larger area is too small to meet the lighting requirements
