Description

A kind of LED light fixture
[technical field]
The utility model relates to a kind of lighting, especially a kind of LED light fixture.
[background technology]
At present the principal mode of the light source of lighting is spot light and line source, and the spot light of indication is meant that in the plane irradiation is equivalent to the light source of the irradiation of any here, is the general name of a class light source of similar incandescent lamp list lamp illuminating effect.So-called line source refers to that in the plane irradiation is equivalent to the light source of the irradiation of a straightway, as fluorescent tube.Illuminated by surface light source is a kind of specific combination lighting system of spot light, and area source is generally formed by the spot light or the line source of intensive combination, area source since luminous soft evenly, be light source than the better more healthy lighting of spot light or line source.
LED is a kind of semiconductor that electric energy can be converted into visible light, and it has efficient height, photochromic pure, light quality height, advantages such as energy consumption is little, the life-span is long, illuminator points of proximity light source, is the novel green light source of 21 century of generally acknowledging in the world.Traditional LED is mainly used in signal and shows field, building aviation obstruction beacon, navigation light, automobile signal light, instrument back lighting, uses also more and more widely in amusement nowadays, building indoor and outdoor, urban beautification, the Landscape Lighting.If LED is adopted in the illumination of China family 1/2nd, the then annual generated energy that can save power station, Three Gorges.
The area source that existing a kind of LED constitutes, as patent application 2006100620897X number, name is called the LED area source, a kind of LED area source is disclosed, comprise LED substrate and several LED that are installed on the LED substrate, the one phosphor plate support around described LED is set on the LED substrate, described phosphor plate support has an outwardly open interior tapered reflecting surface, has reflectorized material on the reflecting surface, install one on the described phosphor plate support and cover described LED and with described LED the phosphor plate of certain intervals is arranged, phosphor plate is towards the coating fluorescent powder of described LED.Phosphor plate adopts light transmissive material to make.The LED substrate adopts Heat Conduction Material to make.The LED substrate is fixed on the housing by means of Heat Conduction Material; this invention forms homogeneous light emitting area on phosphor plate, send very evenly soft light, has avoided the generation of dazzle; thoroughly eliminate dazzling phenomenon, reached vision protection and the thorough effect of eliminating spot light.
The phosphor plate as the luminous intensity distribution plate of the LED area source of said structure is a flat board, whole covering on the substrate with LED, and has certain intervals with LED, therefore, the whole LED area source has higher height and bigger volume, and the whole structure that covers on the substrate with LED of this kind phosphor plate makes and can not make up freely and arrange in pairs or groups between the LED area source that then the LED area source can't carry out modular production.
Existing ordinary luminaire generally all adopts fluorescent lamp or incandescent lamp bulb, and such lighting not only power consumption is big, and light is dazzling.Also have a lot of local LED of employing as lighting, but, do not meet current people's vision requirement, and its light is relatively dimer, is mostly only using as ornament lamp because existing LED encapsulation problem makes the light that LED sent have dazzle.For example the patent No. is 96225173.9 bivalve body No glare bulb, at the two-layer housing of lamp holder outer setting, internal layer shell is scattered light, make it to produce sheen, but the manufacture craft of this its internal layer shell of structure bothers very much, and adopts the filament incandescent lamp bulb, and power consumption is big and heating is high, its shell body is a vitreum, and lamp holder is easy to damage; The patent No. is a kind of curtain wall lamp of 200410033101.5 for another example, and the LED fluorescent tube is housed in box at the bottom of the printing opacity, and a scattering sheet is established in the box bottom at the bottom of its printing opacity, and the lamp that this method is made is very dim though its light is very soft, can not do lighting fully.In a word, the existing scheme that adopts LED as illuminating lamp, light is bright but has dazzle; There is not the effect that does not have illumination again of dazzle.
[utility model content]
The purpose of this utility model is in order to solve the problem of above-mentioned proposition, and the LED light fixture of the evenly soft and free from glare of a kind of excellent in heat dissipation effect, light is provided.
To achieve these goals, the technical solution adopted in the utility model is: a kind of LED light fixture, comprise the light fixture frame, and described frame is provided with groove; Circuit board is equipped with the plurality of LEDs bulb on described; LGP, the one side of described LGP is provided with texture; Reflector layer, described reflector layer are installed in the one side of the band texture of described LGP; And the diffusion layer that is installed in the LGP another side, described circuit board is installed in the groove of frame and is positioned at the edge of described LGP, it is characterized in that be provided with the heat-radiating aluminum plate between described circuit board and described frame, described heat-radiating aluminum plate is embedded on the described frame.
Preferably, the texture of laying on the described LGP is the silk-screen texture.
Preferably, the texture of laying on the described LGP is the frosted texture.
Preferably, the texture of laying on the described LGP is concavo-convex texture.
Preferably, adopt cramp to connect between the described frame.
The utility model compared with prior art its beneficial effect has: because the utility model adopts diffusion layer, LGP, reflector layer to match with the LED bulb, structure and manufacture craft are all fairly simple, the light that the LED bulb sends is through the refraction and the reflection of LGP, and penetrate from diffusion layer through LGP after the reflection of reflector layer, light is evenly soft, free from glare is not dazzling; Illuminator adopts the LED bulb, and light is bright, can be used as lighting and use, and incandescent lamp and its power consumption of fluorescent lamp is smaller relatively; The LED bulb is installed in the hard shell, in frame, there is aluminium base to give LED bulb and circuit board heat radiation, and the peripheral indention of frame has strengthened area of dissipation, solved the big problem of the high heating of LED power, aluminium base is embedded in the frame, has added big and the contact area of frame, also improved radiating efficiency simultaneously widely, make the working time of the present utility model very long, and can the too high damage light fixture of Yin Wendu; Adopt cramp to connect between the frame, do not have the screw screw, make the connection one integrated mass between the frame, profile is more attractive in appearance.Profile of the present utility model is very attractive in appearance, also can play the effect of ornament, is a kind of very both artistic and practical decorating lighting lamp.
