Background technology
In recent years, be accompanied by the development of semiconductor technology and succeeding in developing of great power LED, LED is widely used at aspects such as signal demonstration, back lighting, Landscape Lightings as semiconductor light sources.Along with improving constantly of great power LED light efficiency, led light source begins progressively to enter the general illumination field.Semiconductor lighting is acknowledged as the third generation light source after incandescent lamp, fluorescent lamp etc. with characteristics such as its energy-saving and environmental protection, life-span length.
The following several forms of the general employing of LED light fixture now:
A kind of is that light source is comprised of plurality of LEDs, substitute conventional light source with led array, adopt design philosophy and the design form of conventional lamp, only Drive and Control Circuit and radiating element are adjusted, then put common lampshade, setting angle and the angle of divergence size of LED are not adjusted or designed.Can replace existing conventional light source in this way, and the light fixture external form does not change, but LED spatial light distribution characteristic and conventional light source difference are larger, can reduce on the contrary the utilization ratio of light with the light distributing method of conventional light source, and the heat radiation of led chip also is a very scabrous problem.
Another kind is that plurality of LEDs forms light source with array format, but LED is arranged on the arc-shaped curved surface, adjust the angle of LED with this, such as the disclosed LED street lamp of Chinese patent CN101059228A, LED multiple row multirow in the rectangular area is arranged in length and breadth, between the LED of each column or row and the baseplane of pedestal certain angle is arranged; The disclosed LED light projector of Chinese patent CN2743676Y will be installed the LED seat and be designed to curved surface shaped; Chinese patent CN2874223 discloses the on-plane surface LED lamp that is used for car light, adopts taper, sphere, hemispherical and paraboloidal non-plane printed circuit, the led chip that gathers thereon, and the parabolic back side is provided with fin.
Also have a kind of form of reflection shield that adopts that the spatial distribution of light intensity is adjusted, such as the highly effective slot-shaped reflective cover of Chinese patent CN101101096A, bottom land is arranged led array, utilizes the flute profile reflector to adjust the light intensity spatial distribution.
Having a kind of is that plurality of LEDs distributes with array format again, and installs the angle of divergence of lens or reflector change LED additional at every LEDs, such as the high-power LED street lamp of Chinese patent CN1821651A, and the LED horizontal distribution, and every LEDs has corresponding lens corresponding with it; Perhaps control simultaneously setting angle and the light angle of divergence of LED, such as the LED road-light light-source of Chinese patent CN1936417A, the plane at its each row LED place all has a certain degree with the bottom surface, and every LEDs has corresponding lens supporting with it.
Top several method has improved the light utilization efficiency of LED by number of ways, but also has following shortcoming:
Certain angle that is distributed with owing to LED, therefore its appended wiring board or radiator all must have a certain degree with base, needing to make special mould matches with it, but the Mold Making cost is high, difficulty of processing is large, because angle is non-adjustable after the moulding, a mold is general only corresponding to a kind of luminous form or application scenario, be that the LED light fixture rear light intensity angle distribution of dispatching from the factory can not be changed, reduced the accommodation of light fixture.
