Reflector lamp with high effective luminous energy

Abstract

The invention discloses a reflector lamp with high effective luminous energy, so as to solve a problem that ray effective availability of an existing reflector lamp is not high. The reflector lamp comprises a radiator housing, a lower part is provided with a cavity, a middle part is provided with a platform, and radiator fins on the upper part are connected with the platform. A COB light source is placed on the center of the platform, and faces the cavity on the lower part. A COB support presses the COB light source. A reflection cup is under the COB light source. A front ornamental ring is under the reflection cup. A lens is between the reflection cup and the COB support, and the reflection cup covers the lens. The lens is a bowl-shaped condensing lens formed by an outer contour and an inner contour. The outer contour is a centrosymmetric polynomial aspherical curve. The inner contour is a centrosymmetric Bezier spline curve. The reflector lamp structure of the lens adding the reflection cup greatly improves peak intensity, so most light enters an effective illuminating area, to reduce light pollution and glare, so the reflector lamp saves more energy.

Description

technical field [0001] The invention relates to a spotlight, in particular to a spotlight with high effective light energy through the change of optical structure. Background technique [0002] With the further development of LED light sources, more and more people realize the advantages of this light source: green, energy saving, long life, easy maintenance, etc. In the field of commercial lighting, there is a kind of guide rail spotlight that has flourished with the application of new light sources. Compared with traditional track spotlights, the new LED track spotlights seem to be more suitable for this type of lighting and have a broader application market. In the lighting of major commercial supermarkets, LED track spotlights have become an indispensable type of lamps. [0003] However, with the deepening of the application field, various problems also appear. The present invention will deal with the optical problems of a downlight. Most of the initial optical desig...

Problems solved by technology

[0005] The power of the light source in the above-mentioned first solution cannot be increased, and the power of the entire lamp is not large, and the applicability is not strong; in the second solution, in order to avoid causing larger spot problems, the surface of the lens is treated with moiré or atomization, but This processing method will cause a series of glare problems, and is rarely used; the third solution, the lens and the reflector need to be used together, and specific products have appeared on the market, and the uniformity of the spot and the utilization rate of light energy have been greatly improved. However, due to the diversity of product types, corresponding lenses and reflectors must be developed for each product, and its versatility, development cycle, and cost performance have no great advantages
