Description
Technical field
The utility model relates to a kind of lighting lamp, and in particular to a kind of planar light source lamp group, it has the composite optical plate of diffusion and light harvesting dual-use function, and adds transparent decorated sheet material in the optical sheet top, adds the ornamental of light fixture.
Background technology
The light source that is applied to modular surface light source at present has two kinds haply, and wherein a kind of is cold-cathode tube (CCFL), and another kind then is light emitting diode (LED); Generally be " directly-down light source " as the application of light source with CCFL; After it is arranged in a backboard with plural CCFL, again backboard is installed on the bottom of modular surface light source, makes CCFL light source is provided from the modular surface light source bottom; Since let modular surface light source produce the illumination effect of visual planar light source; In addition, more have with CCFL to be applied to the side-light type light source, it is arranged at CCFL one side of one LGP; With by LGP with ray guidance to the forward light that CCFL was produced, and reduce the cost that is provided with of CCFL.Yet; Owing to adopt CCFL can cause product integral body to have big thickness as the modular surface light source of light source, therefore, to the product requirement of thin typeization now; Again to LED have that volume is little, in light weight, long service life, brightness are high, and characteristic such as power consumption is few; So adopt LED to replace the illuminating source main flow that fluorescent lamp becomes lighting lamp gradually at present, and, simultaneously the modular surface light source of forming be installed in a backboard with the side that said LED is installed in the LGP of modular surface light source as the lighting lamp of light source; The light of LED emission is injected from the LGP side; Cooperate assemblies such as reflector plate via the optical texture of being located at LGP, let light via continuous reflection with refraction and from exiting surface ejaculation LGP, in the hope of illumination effect that area source is provided and meet the slimming product requirement.
At present modal side-light type modular surface light source mainly is made up of light source, LGP, reflecting plate (reflective sheet), diffusion barrier and brightness enhancement film, and its advantage is to have characteristics such as frameization in light weight, slim, narrow, low power consumption.Yet; Because of the structure of side-light type is that light source is placed the LGP side, it is long across the exhibition of whole LGP that the light that is incident to LGP is needed, and along with the increase of light transmission distance; The lightness meeting decays rapidly; So this design is applicable to as undersized area source, rarely be applied to large-sized area source, for example: the large tracts of land interior illuminator.In order to make the side-light type modular surface light source can be applied in the large scale area source; Existing patent discloses the parallel and compartment of terrain of a plurality of side-light type modular surface light sources and is arranged on the same plane; Can be applied to large-sized lighting apparatus by this; And can not increase its thickness by modular surface light source, reach purpose of thinness as the straight-down negative.
Existing side-light type light source mainly is provided with LGP in the reflecting plate of an indentation; And be provided with blooming pieces such as diffusion sheet and light-collecting piece in LGP; Utilize brightening piece (prismatic lens) (BEF) and reflective polarizers (DBEF or CBEF) collocation make and be used for reaching the purpose that light is concentrated, prismatic lens has good collection characteristics (dwindling the dispersion angle of dispersing light source) on optical effect, less light produces total reflection but prismatic lens also lets angle easily; Thereby the service efficiency of reduction light; So some briliancy have relatively high expectations or the application of battery powered modular surface light source on, in order to improve briliancy, increase the light utilization ratio and to save electric power, can use reflective polarizers (DBEF or CBEF) to come to utilize once more light to achieve the goal; By this; To be a little luminous light emitting diode, with a plurality of arrangements, to form the light source of a straight line.Continue it, after light source is imported by the LGP side end face, utilize of the light reflection of zigzag reflector plate light source; Make light projection and dispersing toward the upper surface of LGP; Make light diffusion and evenly distribution through diffusion sheet again, then, utilize light-collecting piece can concentrate on light direction by light; So, the structural design of light source film group according to this is on implementing; Must settle several light emitting diodes, except that the raising that causes assembling man-hour and manufacturing cost, and on reality is used; Because light source is the arrangement of a little luminous light emitting diode in line by several, in the hope of forming the form of a line source, yet; Have the gap between the light emitting diode unavoidably,, therefore in brightness, still have not enough flaw so be projeced into the light of LGP and the light of noncontinuity projection; In addition, the employed diaphragm number of modular surface light source framework increases, comparatively speaking, except meeting causes thickness increases, shortcoming such as more cause the optical efficiency of module whole to reduce, the module cost is high, the assembling yield is limited.
Therefore; The utility model needs two kinds of optical sheets could have the dual-use function of diffusion and light harvesting simultaneously, and on designing, disappearances such as manufacturing cost height and luminance shortage is arranged in view of existing flat light source structure; Be mat its for many years in the manufacturing of association area and assisting a ruler in governing a country of design experiences and knowledge; And, do the research and development improvement upgraded to this existing flat light source structure, in the hope of bringing into play its higher Practical Benefit property through clever thought in many ways.
