Embodiment Construction
[0033] In order to make it easy to understand the technical means, creative features, objectives and effects achieved by the present invention, the present invention will be further explained below in conjunction with specific drawings.
[0034] See figure 2 with image 3 , The lighting fixture includes a housing 2, in which a number of high-power LED light sources are densely arranged. These high-power LED light sources can be arranged in a honeycomb or rectangular array (such as figure 2 Shown).
[0035] Each high-power LED light source includes an LED light-emitting diode 21, and the LED light-emitting diode 21 is covered with a concave mirror 22 for converging light. The light-emitting part of the LED light-emitting diode 21 is located at the focal point of the concave mirror 22. A converging lens 23 is arranged in front of the LED light emitting diode 21, and the focal point of the converging lens 23 is located at the light emitting part of the LED light emitting diode 21. ...

The invention provides a large-power LED light source, a large-power LED illuminating lamp using the same and an application of the illuminating lamp and relates to an LED lighting instrument, in particular to a large-power LED light source, a large-power LED illuminating lamp using the same and an application of the illuminating lamp. The large-power LED light source comprises an LED and a pair of optical collectors which collect light from the LED and is characterized in that the optical collectors are concave mirrors, a light-emitting part of the LED is located at a focal point of the concave mirror; the large-power LED light source also comprises a convergence lens which is located in the front of the LED, the focal point of the convergence lens is located at the light-emitting part of the LED. The invention solves the problem that luminous efficiency of the large-power LED lamp is low and the problem of luminous effect that emergent light form is not full or soft.
Description
Technical field [0001] The invention relates to an LED lighting lamp, in particular to a high-power LED light source, and also relates to a high-power LED lighting lamp using the light source and the use of the lighting lamp. Background technique [0002] At present, the whole world is seeking to solve the contradiction between economic development and energy shortage. With the maturity of light-emitting diodes, namely LED technology, and the rapid decline in cost, LEDs are increasingly used in the fields of automotive lamps, traffic signal equipment and lighting. The development and application of LED lighting fixtures will surely bring broad market prospects and new economic development opportunities to the entire energy-saving lighting and green lighting industry, and high-power LED light-emitting diodes are the inevitable choice for lighting fixtures. [0003] In recent years, in the design and application of such high-power LED lighting products at home and abroad, basically a...
