Description
Technical field
The present invention relates to the lighting apparatus field, a kind of LED reflector lamp of high-effective concentration.
Background technology
In the past, searchlight or the headlamp that is used for motor vehicles such as railway locomotive, motor-car, city underground, light rail train, automobile generally adopted halogen tungsten lamp, Metal halogen lamp or xenon lamp etc. as lighting source, and used traditional parabolic reflector to carry out optically focused.Its shortcoming is that the light efficiency of light source is low, must just can reach certain irradiation distance with very high-power focusing, and such result directly causes the life-span low, and maintenance workload is big, and the frequent damage of light fixture also might bring potential safety hazard.
We know that the life-span of great power LED reached more than the 50000h, in some field, also are used widely, and the LED reflector lamp is also arranged on the market; But because single LED power that approaches spot light character generally is not more than 10W, so LED is mainly used in flashlight at present, the lamp of camping etc. is asked not high civilian occasion; For the locomotive headlamp; The building searchlight, the occasion that night flight lamp peculiar to vessel etc. is had relatively high expectations is used considerably less at home.This is because the restriction of traditional led light source light receiving device (reflector) determines.
Present LED reflector lamp has that to adopt single led light emitting source, its reflector inwall be a complete parabola, and (referring to the accompanying drawing 1) that adopt cellular design also arranged; According to the single face characteristics of luminescence of LED, the hot spot that the LED reflector lamp impinges upon the place ahead mainly contains reverberation, direct light, angle light three parts composition, and each parabola in the cellular reflector is relatively complete; Each paraboloidal axis overlaps with corresponding led light source centre normal; If to the demanding words of hot spot, angle light is almost all useless, the useful just direct light and the reverberation of fraction; Irradiation distance is far away more; Angle light proportion is just big more, and the loss of light is just big more, as shown in Figure 2 like this.And reach higher illumination, led light source just needs bigger power, yet led light source needs certain heat radiation requirement again, and the service life of having reduced the LED reflector lamp.
Summary of the invention
To the deficiency that prior art exists, the object of the present invention is to provide a kind of high-effective concentration, save the LED reflector lamp of energy consumption, longer service life.
For realizing above-mentioned purpose; The invention provides following technical scheme: a kind of LED reflector lamp; Comprise reflector and be arranged on the led light source in the reflector; Corresponding led light source is provided with parabolic reflector in the reflector, and the centre normal of said led light source and the axis of parabolic reflector are an angle setting.
Through adopting technique scheme; Reduced the loss of led light source angle light, letting and penetrating the wide part of going is reverberation, makes optically focused more efficient; In reaching the zone under the situation of required illumination; Reduced the led light source power demand, more energy-conservation, and prolonged service life of LED reflector lamp.
The present invention further is provided with: the axis angle of the centre normal of said led light source and parabolic reflector is set between 45 ° to 90 °.
Through adopting technique scheme; Reduced the loss of led light source angle light greatly, let penetrate the light go more major part be reverberation, further make optically focused more efficient; In reaching the zone under the situation of required illumination; Further reduced the led light source power demand, more energy-conservation, and prolonged service life of LED reflector lamp.
The present invention further is provided with: said led light source is arranged on the focal position of parabolic reflector.
Through adopting technique scheme, make that reverberation is parallel all, further improves the high efficiency of optically focused.
The present invention further is provided with: the led light source in the said reflector is provided with several, correspondingly with each led light source is provided with a parabolic reflector, and the centre normal of each led light source all axis of the parabolic reflector corresponding with it is an angle setting.
Through adopting technique scheme, improved the illumination in requiring the zone.
The present invention further is provided with: said reflector is bowl-shape setting; Said each parabolic reflector is on the not confocal inwall that is distributed in reflector; Said reflector inside bottom is provided with lamp socket; Said led light source is distributed in respectively on the lamp socket sidewall of corresponding each parabolic reflector, and each led light source is arranged on the focal position with its corresponding parabolic reflector.
Through adopting technique scheme, the wide part that lets the ejaculation of each led light source go is a reverberation, and the reverberation of this part is parallel all, and collection has higher illumination a long way off in requiring the zone, at utmost avoided the loss of angle light.And profile can be flexible and changeable, and adaptability is stronger.Through the contrast experiment, the light cup of identical bore, the light utilization of traditional light cup only has an appointment about 30%; And this light cup light utilization of the present invention can reach 70%-80%; In view of the above, if reach identical illumination, use the power of the required light source of light cup of the present invention to have only about 40% of the traditional light cup of use; Can under the prerequisite that meets the demands, save energy consumption like this, improve product service life (caloric value is little).Penetrate occasion far away in requirements such as headlamp, searchlights, of far-reaching significance.
Below in conjunction with accompanying drawing the present invention is further described.
