Description
Technical field
The present invention relates to lighting field, particularly, relate to a kind of rectangular optical reflecting light source structure.
Background technology
Semiconductor lighting is generally promoted, and take LED light fixture as main light fixture extensive application.Wherein the technology such as LED-backlit source, LED flat lamp does not also have full maturity, and main cause is: the spot light of (1) LED chip, and while forming planar light source, conversion efficiency is on the low side; (2) LED distribution of light is lambert's type, also needs the structures such as film and diffusion barrier of glistening while manufacturing planar light source.(3) a kind of lateral type structure of the employing backlight such as television set, mobile phone is more general, but light efficiency is lower; (4) television set also has the straight-down negative of employing structure, and straight-down negative light efficiency is high, but still needs diffusion barrier technology.
Nowadays, LED technology also occurs adopting reflector reflection or lens reflection to make the luminous luminous intensity distribution of LED not occur youth uncle type phenomenon, avoid the problem that occurs that uneven illumination is even, but adopt LED light source can greatly weaken the intensity of illumination through lens reflection, reduced the utilization rate of light, and most of reflectors that still adopt revolving body on the existing market of employing reflector reflection technology, its range of exposures is circular, but some situation needs different ranges of exposures, as rectangle range of exposures, this reflector can not meet the demands.
Also there is forming the reflector of rectangle range of exposures in prior art, Chinese Patent Application No. is 201110105807.8, it discloses a kind of rectangle transmitter and LED light fixture, this rectangle transmitter is because the difference of its lateral reflection face can produce rectangular shaped light source, but the not isostructure due to its lateral reflection face, manufacturing process and manufacturing process are comparatively complicated, and this invents not mentioned heat abstractor, although its transmitter and light fixture volume size are less, if but do not have heat abstractor still the life-span of lamp to be impacted for the permanent use of LED lamp, in the course of time can affect illumination, cause uneven illumination even.
Another part of Chinese Patent Application No. is 200810155880.4, it discloses a kind of high-power LED street lamp fixture, this invention can produce rectangular illumination region and also be provided with heat abstractor, although but the recessed rectangular pyramid shape reflector that the reflector of this invention adopts the reflector of four triangles or inverted trapezoidal to form can produce rectangular illumination district, but the side structure of its reflector is entirely not identical, manufacturing process or some complexity, and reflecting effect not than camber reflection in the face of the reflection of light good.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of diffusion barrier part that can save light source, a kind of rectangular optical reflecting light source structure of larger raising light source light emission rate and effectively distribute heat.
Another object of the present invention is to simplify the manufacturing process of the reflector that produces rectangular shaped light source, reduces the manufacturing cost of rectangular shaped light source.
For achieving the above object, technical solution of the present invention is as follows:
A kind of rectangular optical reflecting light source structure, by a plurality of square optical reflector, arrange and form rectangular array, the bowl structure that each square optical reflector is upper opening, the bottom of bowl structure and four faces are around cross section and are parabolical curved surface, and the top of each square optical reflector is provided with LED light source.
Square optical reflector of the present invention can be that four lateral reflection faces and cross section identical with the equal structure of bottom reflection face is parabolical curved surface, also can be that four lateral reflection face structure cross sections identical but bottom reflection face different structure are parabolic surface, two kinds of structures like this can produce high reflection efficiency to light, form uniform rectangular shaped light source.
Preferably, described LED light source and square optical reflector are positioned at same central axis.
Preferably, described square optical reflector is coated with optical reflectance coating.
Preferably, described optical reflectance coating is aluminium film.
The present invention is coated with in square optical reflector the reflecting effect that optical reflectance coating can strengthen light, plays one and adds intense light irradiation effect.Reflectance coating can also can select other to meet other reflectance coatings of reflectivity requirement by aluminium film.
Preferably, described a plurality of square optical reflector connects by mounting bracket, and described LED light source is arranged on mounting bracket, and LED light source head is towards square optical reflector bottom reflection face.
Preferably, described mounting bracket comprises rectangular shaped rim, and described rectangular shaped rim is provided with the mounting rod of parallel a plurality of installation LED light sources.
Preferably, described mounting bracket is provided with radiating piece.
The present invention also possesses good heat sinking function simultaneously, can guarantee that uniform illumination is not subject to the temperatures involved of light fixture, long service life.
Preferably, described rectangular optical reflecting light source structure front is provided with printing opacity safety glass backplate.
Creativeness of the present invention is: adopt square optical reflector to carry out light reflection to LED light source and produce square hot spot, and the square light of array penetrate reflector can be square hot spot combination results rectangular shaped light source.The production method of this rectangular shaped light source is distinguishing with prior art, in prior art, great majority are all directly to produce rectangular shaped light source, by array-type LED light source, form a large rectangular shaped light source again, the reflecting cup structure adopting like this must side surface of emission structure can not be accomplished striking resemblances exactly, at most two pairs of difference are identical, and some technology are even more complicated.And the present invention produces four lateral reflection face structures of the square reflector of square hot spot, be all identical, manufacture craft is simple, can save manufacturing cost; Meanwhile, it is parabolic surface that the structure of lateral reflection face adopts cross section, and such structure has the reflecting effect of pair spot light very good, can produce uniform lighting effect, does not need to use diffusion barrier technology.
Compared with prior art, the beneficial effect that the present invention has is:
The present invention is that all even light extraction efficiency is high in single square optical launcher bright dipping, and outgoing square hot spot, a plurality of square optical launchers are arranged with array, can form rectangular shaped light source, save the diffusion barrier part of light source, larger raising light source light emission rate, adopts the lateral reflection face manufacturing process that structure is identical easy, saves the cost of light source.
