Abstract

The utility model discloses an LED down lamp which comprises a housing, a light-transmitting board and an LED light source, and is characterized in that an optical processing film is arranged between the light-transmitting board and the LED light source and comprises a first polyester film and a second polyester film, wherein the opposite surfaces of the first polyester film and the second polyester film are respectively formed with a large number of micro lenses, and the long axles of the micro lenses on the first polyester film and those of the micro lenses on the first polyester film are arranged in different directions.

Description

The LED Down lamp

[technical field]

The utility model relates to the LED lighting technical field, or rather, relates to a kind of LED Down lamp.

[background technology]

Down lamp is a kind of lighting that is embedded into light down-ejection type in the ceiling.Its maximum characteristics are exactly to keep the integral body of building decoration unified and perfect, can not destroy the perfect unity of furred ceiling art because of the setting of light fixture.Its structural advantages is that light source is hidden in building decoration inside, and light source does not expose, free from glare, and visual effect is soft, even, is applicable to environment such as market, supermarket, office building, hotel, coffee shop, family.Along with development of science and technology, Down lamp is also constantly being weeded out the old and bring forth the new: from initial incandescent lamp electricity-saving lamp finally.Along with high power savings advantages and the LED technology of LED are progressively full-fledged, the LED Down lamp also occurs on market successively, common in the market LED Down lamp is conventional lighting sources simply to be replaced to LED make basically, what have also can form the frosted layer and carry out simple optical treatment on light-emitting plate, yet there are the following problems for this series products: bright dipping is inhomogeneous, dazzle etc. is arranged, the desirable light effect that goes out that this and people pursue has very big gap, so the appearance of a kind of new LED Down lamp of market demand.

[utility model content]

The technical problem that the utility model solves is to overcome the defective that prior art exists, and a kind of LED Down lamp that light effect is good, light efficiency is high that goes out is provided.

The utility model is achieved through the following technical solutions: a kind of LED Down lamp, comprise housing, light-passing board and led light source, described LED Down lamp disposes a light and handles film between described light-passing board and led light source, described light is handled film by comprising first polyester film and second polyester film, described first, second polyester film opposite face is formed with a large amount of lenticules respectively, and the lenticule major axis on described first polyester film is arranged on the different directions with lenticule major axis on second polyester film.

Lenticule on described first, second polyester film has identical refractive index.

Described light is handled film and is also comprised a separating layer, and this separating layer is arranged between described first, second polyester film, and described first, second polyester film is an one by described separation layer pressing.

The refractive index of described separation layer is lower than the lenticular refractive index on described first, second polyester film.

Lenticular refractive index on described first, second polyester film is 1.55, and the refractive index of described separation layer is 1.42.

Lenticule major axis on described first polyester film and the lenticule major axis on second polyester film are set to 90 degrees mutually.

A kind of LED Down lamp, comprise housing, light-passing board and led light source, described LED Down lamp disposes pair of lamina light and handles film between described light-passing board and led light source, described double-deck light processing film is pressed together by pressure-sensitive adhesive (PSA) by two above-mentioned light processing films and forms.

Compared with prior art, the utility model is handled film by set up special light in existing LED Down lamp, has improved the light effect that of LED Down lamp significantly, and has still kept higher light efficiency.

[specific embodiment]

See also illustrated in figures 1 and 2ly, the LED Down lamp 9 that the utility model disclosed comprises that housing 1, light-passing board 2, light handle film 3, reflector 4, led light source 5 (containing circuit board), radiator 6, power supply 7 and power supply fixture 8.Described light is handled film 3 and is arranged between light-passing board 2 and the led light source 5, is used to handle that led light source 5 sends or project light after reverberation bowl 4 reflections handles all light paths on the film 3.

See also shown in Figure 3, described light is handled film 3 by comprising first polyester film 31, second polyester film 32 and be located at first, second polyester film 31, interlayer 33 between 32, described first, second polyester film 31,32 opposite faces are formed with a large amount of lenticules 310 respectively, 320, lenticule major axis on described first polyester film 31 and lenticule major axis on second polyester film 32 are arranged on the different directions (being 90 ° of angles between two major axis in the present embodiment is provided with), described first, lenticule 310 on second polyester film, 320 have identical refractive index (being 1.55 in the present embodiment), the refractive index of described interlayer 33 (being 1.42 in the present embodiment) is lower than described first, lenticule 310 on second polyester film, 320 refractive index, described first, second polyester film 31,32 is one by described interlayer 33 pressings.

The light processing film 3 that Fig. 3 disclosed is an individual layer, when also can being bilayer or multilayer, it is described to see also Fig. 4, and this figure has disclosed a kind of double-deck light and handled film 3 ', and it is to be pressed together by pressure-sensitive adhesive (PSA) by the light processing film 3 that is disclosed among two Fig. 3 to form that this light is handled film 3 '.

Generation type and the manufacture craft of handling the lenticule 310,320 on the film 3 about the structure and the light of LED Down lamp are disclosed by prior art, are not giving unnecessary details at this.

More than describing is embodiment of the present utility model only, forgives and can understand, and under the prerequisite that does not depart from the utility model design, all should be included within the technical conceive of the present utility model simple modification of the present utility model and replacement.
