Description

The led light source LGP

Technical field

The utility model relates to field of illumination lamp technology, particularly relates to a kind of led light source LGP.

Background technology

LED is the abbreviation of English Light Emitting Diode (light emitting diode), and it is the high-performance solid light source that a kind of novel faint electric energy of usefulness just can be luminous.

First commercialization of 20 middle of century LED light emitting diode appears on the market, and through the course in surplus 50 years, its performance was constantly improved, and manufacturing cost constantly descends, and has obtained the rapid progress that attracts people's attention.LED has obtained using widely with advantages such as its intrinsic high efficiency, long-life, low-loss, vibration resistance, response speed piece, volume are little.Along with improvement of Manufacturing Technology, luminous efficiency and the luminous intensity of its single LED constantly are improved, and along with the improvement of LED performance and the enhancing of power, it has been possible that single LED makes the highlight illumination light fixture, the LED product has become the new product that has influence in the application of lighting field.

Because the characteristics on its product structure are limit, the light-emitting area of LED is a directive property light source semi-sphere, the light that it sent is a directive property light source and the planar scattered light of angle light source hemisphere is arranged, for the light that can make scattering shines out forward as far as possible, reach the intensity of illumination (for identical irradiation distance) of broader angle and smooth light source or farther irradiation distance (for identical luminous intensity), the technical staff has done a large amount of research and trial.

The day for announcing is on November 7th, 2007, notification number is to disclose a kind of " LGP structure-improved " in the Chinese patent of CN200972511Y, it mainly comprises one by the made light guide sheet of high light transmissive material, described light guide sheet the place ahead is provided with a clear thorough photic zone, its back side is provided with a reflecting layer, and this reflecting layer and photic zone are one-body molded, and, the shape of being somebody's turn to do " LGP structure-improved " is confined to box-shaped, and the light of illuminating source imports from the straight line side of box-shaped.Thereby also be subjected to the limitation of box-shaped shape by the illuminating product of its manufacturing.And in the real life process, illuminating product shape quantity in the form of annular discs is also quite a lot of, thereby the market demand of the LGP of round sheet is also very big.

The utility model content

Technical problem to be solved in the utility model is, satisfy the active demand in lighting market, a kind of led light source LGP is provided, utilize this led light source LGP to cooperate the illuminating product of producing with corresponding assembly, light import the back reflective evenly, can not produce ghost image, make the light fixture of making not only can produce enough brightness, and light stability can not glimmer, and allow eyes not have dazzling sensation, again with power saving and athermic advantage.

The technical scheme that its technical problem that solves the utility model adopts is: the led light source LGP, comprise one by the made photic zone of high light-transmitting materials, it is characterized in that: also comprise the reflector layer that brushing is closely linked at photic zone upper surface and described photic zone, the rounded sheet of described led light source LGP, lower surface of euphotic upper surface, reflector layer (side to light) and upper surface are respectively that parabola revolves three-sixth turn along the axle center of led light source LGP and the parabolic surface shape that forms.

In technique scheme, closely combine through reflector layer and the photic zone upper surface that the stack brushing forms by two-layer above composite; Bottom in the reflector layer can be one deck reflectorised paint, also can be other reflectorized material, and the reflective enamelled coating and the photic zone upper surface of brushing closely combine; Superficial layer in the reflector layer can be the mixture layer of lacquer type organic coating and bead, also can be other mixtures of material layer, and the lacquer type organic coating of brushing and the mixture layer of bead and reflective enamelled coating closely combine.

For the symmetric points symmetric design led light source more than 2 is arranged with the center of circle in the side of led light source LGP circumferential edge; Described each led light source is positioned on the corresponding parabolic focus respectively.

The beneficial effects of the utility model are: one, because the rounded sheet of led light source LGP, and suitable for making becomes discoid illuminating product, and can not increase invalid, and this is that the LGP of the box-shaped of prior art is difficult to realize; Two, the lower surface of euphotic upper surface, reflector layer and upper surface are the paraboloid of revolution respectively, but not the translation parabola of prior art, be that parabola revolves three-sixth turn along the axle center of led light source LGP and the parabolic surface shape that forms, with its center of circle led light source more than 2 is arranged for symmetric points design at the LGP side of circumferential edge, described each led light source is positioned on the corresponding parabolic focus respectively, the light of led light source reflects through reflector layer, form collimated light beam, make the light homogeneous and bright of throwing photograph, can not produce ghost image; Three, reflector layer and the photic zone through brushing closely combines, and makes optical attenuation littler, and makes the structure of led light source LGP become more suitable, is convenient to production, easy to assembly, and production cost is low; Four, utilize this led light source LGP to cooperate corresponding assembly can make ultra-thin illuminating lamp, its light transmission is good, long service life, light stability can not glimmer, and allow eyes not have dazzling sensation, with power saving and athermic advantage, be easy to apply again, do not pollute the environment after LGP is discarded, meet the energy-conserving and environment-protective requirement.
