Background technology
Light emitting diode (Light Emitting Diode, LED) as solid state light emitter of new generation, have the many merits such as energy-conserving and environment-protective, extra long life, antivibration, progress along with technology, its light efficiency improves constantly, substitute gradually all kinds of conventional light source, be widely applied in the fields such as demonstration, illumination.Wherein because LED light source is point source of light, exiting surface is less, very easily causes the human eye vision discomfort, produces dazzle.
In prior art, because LED luminous has directionality, for unidirection luminous, the bright dipping mode of existing LED lighting, be all luminous LED directly towards the light-emitting area (straight lighting-out tpye) of light fixture, or the light-emitting area of side direction light fixture (side is illuminated); The anti-dazzle method of existing LED lighting mainly contains: adopt the light transmissive material with light diffusion or atomization to shelter from LED light source, reduce the identification of human eye to luminous LED light source, or on fitting structure, design certain shading angle, make human eye can not see luminous LED light source in certain elevation coverage.
The light transmissive material that employing has light diffusion or an atomization shelters from the anti-dazzle mode of LED light source, LED light source and the light transmissive material spacing less in, when perhaps the LED light source luminous intensity is larger, just can't avoid human eye directly to see LED light source, thereby produce dazzle; And the anti-dazzle mode of the certain shading angle of design on the employing fitting structure has certain limitation to the lighting angle of light fixture own, and can't avoid human eye directly to see luminous LED light source in angle arbitrarily.
The utility model content
Technical problem to be solved in the utility model is: a kind of indirect lighting LED light fixture is provided, not only can avoids the generation of dazzle fully, and reduce weight and the manufacturing cost of light fixture, have better economic benefit.
For solving the problems of the technologies described above, the utility model proposes a kind of indirect lighting LED light fixture, comprise the electronic circuit board that is provided with some LEDs light sources, also comprise reflector, be provided with the face-piece of through hole, described reflector is located at the cavity that forms accommodating described electronic circuit board on face-piece, described electronic circuit board is arranged on face-piece, and described LED light source is luminous towards the reflector inwall.
Further, described through hole is provided with diffuser.
Further, the quantity of described electronic circuit board is at least one.
Further, described face-piece is that metal material is made.
Further, the inner surface of described reflector is to form the optical surfaces such as curved surface, plane.
Further, described face-piece is provided with annular boss, and described electronic circuit board is arranged on the top of described boss, and described reflector is located on the lateral wall of boss, the madial wall of described boss surrounds and forms described through hole, and the madial wall of described boss is provided with diffuser.
Technique scheme has following beneficial effect at least: the utility model is by being located at reflector the cavity that forms accommodating described electronic circuit board on face-piece, electronic circuit board is arranged on face-piece, LED light source is luminous towards the reflector inwall, realize that the people can directly not see emitting led light source under any visual angle, can avoid the generation of dazzle fully; Electronic circuit board directly is combined with face-piece, and by face-piece, LED light source is dispelled the heat, and without mating in addition lamp radiator spare, reduces weight and the manufacturing cost of light fixture, has better economic benefit.

Fig. 2 is the cutaway view of the utility model indirect lighting LED light fixture.
Fig. 3 is the schematic diagram during light refraction in the utility model indirect lighting LED light fixture.
Fig. 4, when in the utility model, human eye is watched indirect lighting LED light fixture, avoids producing the principle schematic of dazzle.
The specific embodiment
It should be noted that, in the situation that do not conflict, embodiment and the feature in embodiment in the application can combine mutually.Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1 and Figure 2, the indirect lighting LED light fixture of the utility model embodiment comprises some LEDs light sources 1, face-piece 2, reflector 3, diffuser 4, electronic circuit board 5, wherein, face-piece 2 is provided with a through hole 21 be used to deriving light, it is made for metal material, be conducive to heat conduction, heat radiation, face-piece 2 is provided with an annular boss 22, and the inner ring sidewall of boss 22 surrounds and forms the through hole 21 that runs through face-piece 2.Reflector 3 is located at the cavity that forms a holding electronic wiring board 5 on face-piece 2, reflector 3 is used for reflecting the light that LED light source 1 sends, light is throwed downwards, reach the purpose of illumination, particularly, reflector 3 cooperatively interacts and is connected with the outer ring sidewall of boss 22 by its inwall, more firm in order to cover, and can on the inwall of reflector 3, apply glue; The inner surface of reflector 3 is other optical surfaces such as curved surface, plane.Diffuser 4 is arranged on the madial wall of boss 22, perhaps also can be arranged on the top of boss 22 so that through hole 21 is sealed, the inside of protecting on the one hand this light fixture is touched arriving not, avoid the impurity such as dust to enter, can make on the other hand part light carry out secondary or Multi reflection, make the light fixture bright dipping more even.The electronic circuit board 5 that is welded with some LEDs light sources 1 is loop configuration, and it is adjacent to the top that is fixed on annular boss 22, and guarantees that LED light source 1 is luminous towards reflector 3 inwalls.LED light source 1 is welded on electronic circuit board 5.
As another kind of embodiment, the quantity of electronic circuit board 5 can be one, two or more, can need to determine according to actual illumination, such as, can two circulating electron wiring boards 5 be installed on the top of boss 22, improve the brightness of illumination, the shape of electronic circuit board 5 is not restricted to circle, also can be other shape.
During work, as Fig. 3, LED light source 1 can upwards send the light of certain angle after connecting externally fed, these light are after the printing opacity effect and reflex of the diffuse reflection effect of the reflecting curved surface of reflector 3, diffuser 4, changed the direction of propagating, final below of investing the light fixture exiting surface by through hole 21, realized the purpose of throwing light on.
