Abstract
The invention relates to a luminous structure, which comprises a light source and a trumpet-shaped reflecting cavity. The light source comprises a cylinder-shaped or a cone-shaped base and a plurality of LEDs (light emitting diodes) distributed around a side of the base, an inner wall of the reflecting cavity is a curved reflecting surface, and the light source is arranged in the reflecting cavity and is located at the bottom of the reflecting cavity. The luminous structure adopts a side-emitting light source and produces emergent lights after being reflected on the reflecting surface, so that glares can be effectively avoided. The reflecting surface is a paraboloid, the LEDs are arranged on focuses of the reflecting surface or on a straight line which can produce parallel emergent lights, so that emergent lights with small light-emitting angles can be produced. By using multiple LEDs, even heat distribution can be guaranteed, middle power LEDs can be selected and used, therefore, heat-radiating is convenient while cost can be lowered. The invention further relates to an LED lamp.

Background technology
Because LED (Light Emitting Diode; Light emitting diode) fast development of technology, the light efficiency of LED continue to improve and cost continues to descend, and add that the LED standard establishes gradually; The LED illuminating product no longer is confined to engineering and commercial illumination, and spreads to civilian lighting of home gradually.Wherein the LED shot-light is the light source of a kind of folk prescription to bright dipping, like BR, MR, PAR class light fixture.According to the Energy Star standard, MR class shot-light lighting angle need be less than 50 °, and PAR class shot-light lighting angle need be less than 65 °.LED Down lamp, Ceiling light, Projecting Lamp or the like then are the unidirectional illumination light fixtures that directly combines with LED integral body, also need less lighting angle in general use occasion.
Existing LED shot-light, Down lamp, Ceiling light and Projecting Lamp etc., most of lens or reflector that uses many great power LEDs to mix All-in-One realized.But because the price of great power LED is higher, the cost of this scheme is higher, is not suitable for civilian popularization.In addition, the shot-light of realizing in this way owing to demonstrate position, a plurality of hole in appearance, has very big-difference with traditional Halogen lamp LED in appearance, is difficult for being accepted by market.
Another kind of newer implementation is to mix corresponding lens or reflector realization by single integrated LED.With respect to the mode of plurality of LEDs, this scheme especially form of reflector is accepted by market in appearance more easily.But because the integrated LED heat is concentrated, the heat build-up that is produced can cause its whole less stable.In addition, because the integrated optical source light-emitting area is bigger, in order to improve light utilization efficiency, lens and reflector need bigger height, cause structurally having limited the size of power supply.
In addition, though the integrated LED of equal luminous flux is more cheap slightly than manying a great power LED on price, but still there is not significant advantage.For the cost performance that improves, many even cloth of middle power LED of use are also arranged on surface plate, add in the above that again the mode of frosted or diffuser cap is done light-emitting area evenly, prevent to see the lamp pearl.But this mode can not realize less lighting angle.
