High-power LED concentration system

Abstract

The invention provides a large-power LED concentrating system in an illuminating apparatus, comprising an ellipsoid light reflector and a plurality of LED modules; wherein, the LED modules are evenlyarranged at the periphery of the ellipsoid light reflector; the emergent light surface of every LED module is provided with an optical collector group; the optical collector group comprises an outer cover of the optical collector and a lens arranged in the outer cover of the optical collector; an optical collector support is arranged opposite to the ellipsoid light reflector; the optical collectorsupport is provided with mounting holes with different angles; the optical collector groups are respectively embedded in the mounting holes on the optical collector support. In the system, the structure scheme of the ellipsoid light reflector and the optical collector groups is adopted to lead a plurality of LED irradiating lights to be superimposed mutually to form pointolite and reflect to a second focus, so that the needed luminous flux is achieved and the requirement of the large-power LED concentrating system is met.

Description

Technical field: [0001] The invention relates to a light concentrating system in an illuminating device, in particular to a high-power LED light concentrating system composed of an ellipsoid reflector and a condenser lens group. Background technique: [0002] At present, as a new type of light source, LED has the advantages of low energy consumption, less heat generation, high luminous efficiency, no pollution, energy saving and environmental protection, and long service life. Therefore, LED has been widely used in the lighting field. However, since the power of a single LED cannot be made very large, a combination of multiple high-power LEDs must be used to obtain a larger luminous flux. Commonly used lamps and lanterns in general film and television lighting, such as projection slides, projectors, movie projectors or follow spot lights, etc., all use ellipsoidal reflectors as the concentrating system. Such as figure 1 As shown in the concentrating system of traditional f...
