Abstract

The invention discloses a spotlighting searchlight and a lighting method of the spotlighting searchlight and relates to the technical field of lamp lighting. The spotlighting searchlight comprises a reflector, a fixing frame, a Fresnel lens and a light source. The light source comprises a substrate and a light emitting face which are welded into a whole. The substrate is fixed into the reflector and is located at the end far away from a light outgoing opening. The fixing frame is a circular truncated cone frame. One end of the fixing frame is located outside the substrate and is fixedly connected with the reflector. The other end of the fixing frame is provided with a fixing ring in a welded manner and extends towards the direction of the light outgoing opening. The Fresnel lens is embedded into the fixing ring. The lens surface, located on the side of the fixing frame, of the Fresnel lens is a smooth surface, and the lens surface, located on the side of the light outgoing opening, ofthe Fresnel lens is engraved with multiple concentric grooves. The spotlighting searchlight can solve the problems that an existing spotlight is low in luminous efficacy utilization rate and cannot achieve large-power small-angle spotlighting, achieve ultra-high-power LED remote spotlighting and greatly improve the luminous efficacy utilization rate, the size of the lamp is reduced, the structureof the lamp is simplified, and the product application flexibility is improved.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a spotlight searchlight and a lighting method thereof. Background technique [0002] Most of the light sources of existing LED spotlights use low-power LED lamp beads arranged in an array, each lamp bead contains a small lens, and the light efficiency utilization rate is low, and it is impossible to achieve high-power and small-angle spotlight. If you want to obtain greater illuminance at a longer distance, you must continuously increase the number of LED lamp beads and lenses, so that the volume of the lamp continues to expand, but the increase in volume limits the installation and application of the lamp. Therefore, it is necessary to design a lamp that can achieve high-power and small-angle spotlight on the basis of the existing volume. [0003] By adopting three key elements of high-power fluorescent ceramic LED light source, reflector and Fresnel lens, the present inventio...
