Description
Technical field
The present invention relates to LED lighting field, specifically, relate to a kind of LED panel light.
Background technology
One, the overview of LED panel light
LED panel light is the indoor illumination light fitting of a top grade, and its outer rim is formed through anodic oxidation by aluminium alloy, and light source is LED, and whole Design of Luminaires is attractive in appearance succinctly, atmosphere is luxurious, and existing good illuminating effect, can bring beautiful impression to people again.LED panel light design is unique, and light forms the uniform flat luminous effect of one after the LGP of high transmission rate, and illuminance uniformity is good, light is soft, comfortable and not blind bright, can effectively alleviate kopiopia.LED panel light can also radiation proof, the skin that can not stimulate pregnant woman, old man, children.
LED panel light is widely used, the existing trend that replaces Grille lamp; LED panel light is mainly used in: 1, ceiling (replacing original Grille lamp); 2, wall (not only serve as lighting use, also there is artistic expression); 3, fixing body (pursuing practical and artistic combination, convenient and simple installation); 4, other (also can be used on other place, as in railroad car or Large-scale Mobile car, sales counter etc.).
LED panel light adopts ultra-high brightness LED as light source, be applicable to hotel, bar, western-style restaurant, coffee shop, at home interior decoration, etc. room lighting, can directly substitute original conventional fluorescent lamps, and its brightness is higher.Main performance and the feature of LED panel light are as follows: 1, LED panel light flexible design: LED is a kind of point-like illuminator, designer is by the flexible combination of point, line, surface, can design by customer requirement the light source of various difformities, variable grain, its design is very flexible.2, LED panel light illumination is high: LED panel light has adopted luminous uniform reflective panel and sealed design, coordinates efficient LGP, and aluminum alloy materials makes, and illumination effect is even, and illumination is higher.3, the heating of LED panel light is few: LED panel light external form is frivolous, and heat sinking function is complete, and power is low, and heating is few.4, the LED panel light life-span is long: the theoretical life-span of LED reaches 100,000 hours, and as calculated by 8 hours every days, its theoretical life-span is more than 27 years; Wherein, the theoretical life-span of CPL Lamp cup even exceedes more than 100,000 hours.5, LED panel light lamp variation pattern is various: LED panel light can regulate according to different needs and environmental change photochromic, and not only there is no radiation and dazzle the generation of light, and can vision protection, photochromic more gentle.6, LED panel light lamp antivibration power is strong: in LED panel light, LED light source is a kind of high hardness resin illuminator but not tungsten filament glass etc., is not easy to damage, and therefore its antivibration power is relatively high, and environment temperature adaptive faculty is strong.7, LED panel light control ability is strong: LED panel light can carry out by external controller the control of various dynamic routines, can carry out the regulation and control of colour temperature and the adjusting of bright-dark degree.8, the power consumption of LED panel light is low: meanwhile, LED panel light lighting engineering or a green lighting technique, product is not mercurous, discarded object is few, manufacture process exists pollution hardly; Capable of circulation, callable feature that semiconductor lighting has, has important function to the sustainable development of economic society.
Two, the problem that LED panel light exists
At present, the panel light on market is mainly divided into two classes: the illuminated panel light of straight-down negative panel light and side.
Straight-down negative panel light has the following advantages: 1, light efficiency is high, and through diffuser plate direct irradiation out, the utilization rate of light is higher for the light that LED sends, and the overall light efficiency of light fixture is high; 2, save the cost of LGP, broken the dependence to LGP, light fixture cost is lower, designs more flexible; 3, lightweight, to save after LGP, light fixture weight can alleviate greatly, saves cost of transportation; 4, lamp life extends, and the diffuser plate in panel light does not contact with heat generating spot, and its residing temperature is much lower, can ensure the longer life-span.Straight-down negative panel light has above advantage, has following shortcoming simultaneously: the light direct beam that 1, LED sends gets off, and sends by diffuser plate, inevitably like this can make to have on light fixture speck; And to eliminate speck, and need two approach: a. must strengthen the spacing of LED light source and diffuser plate, cause like this thickness of light fixture to increase, lamp outer casing cost increases, and thickness increases the transmission path that can increase light simultaneously, and light fixture light efficiency reduces; B. add the arranging density in headlight pearly-lustre source, increase cost, increase the power of light fixture, and some occasion does not need so bright light fixture.2, the fixation problem of lamp pearl, if adopt full wafer aluminium base, cost will be very high, if adopt bar shaped aluminium base, has and be difficult to fixing and orientation problem.3, heat radiation difficulty strengthens, its postnotum generally adopts iron plate, or the aluminium base that 0.8mm is thick, large-area like this postnotum is easy to distortion after installation, to making to occur gap between lamp plate and postnotum, the radiating condition variation of lamp plate, and lamp pearl quantitative requirement is too much, cause power to strengthen, increase caloric value.
Comparatively speaking, be more inclined to use now the illuminated panel light of side, straight-down negative panel light power area, thickness under square one strengthen compared with the illuminated panel light of side, not only cost-saving, the perfect lighting area but also energy-conservation that increases.The structure of the illuminated panel light of side mainly comprises: aluminium chassis, light diffusing sheet, LGP, reflective sheeting, LED light source, light source substrate, power drives etc., wherein light diffusing sheet and LGP are the cores of the illuminated panel light of side.LGP reflects side LED light, reflect by site and changes light angle ejaculation, thereby converts line source to area source.The light that light diffusing sheet penetrates LGP more enters one deck and evenly sheds, and forms the uniform area source of light, plays a part to block site simultaneously.But existing side luminescent panel lamp only just can reach large-area exiting surface by LGP, and along large area toward central light strength more weak (determine according to the LGP design in LGP, but inevitably light being lossy in the time propagating along medium); And the utilization rate of the general amount of light to LED lamp pearl is too low, when side-looking, easily see lamp pearl, cause producing hot spot, between aluminium frame and exiting surface, have the inconsistent phenomenon of bright line or brightness.
Moreover, the Yuan Jian ﹐ reason that LGP in the illuminated panel light of side also belongs to more difficult making is to be covered with towards the one side of light source the leaded light picture and text that these light guiding points of Dao Guang Dian ﹐ form by LGP, and (patterns) ﹐ is presenting by dredging close arrangement, and how arranging these light guiding points, just can to reach needed briliancy and the uniformity be a large problem.Ling Wai ﹐ may become Chi Qu ﹐, and this is also the large problem that restriction LGP uses in the manufacturing process of LGP or between the storage life.The preparation method of LGP is mainly divided into two kinds: the brush and non-printing-type of screen printing; The brush LGP small investment of screen printing, does not need used device, completely can manual operations, cost is low, production efficiency is high, technical matters is very easy to grasp, but the brush LGP of screen printing to the refraction effect of light poor than non-printing-type; Although non-printing-type LGP has good light refraction effect, investment is large, the difficult grasp of production technology, needs professional equipment and production efficiency low simultaneously.The intensity of the sheet material after its engraving can be destroyed, and wire casing and shrinkage pool are easily stored dust simultaneously, and production and application are brought to a lot of problems.
In prior art without the LED panel light such as application number a kind of free from glare that is CN201120156724.7 of LGP, not only need the distance that strengthens both sides LED lamp to increase light-emitting area, and LED lamp needs mating cavity height just can reach the effect of total reflection, and however this invention still can not meet the bright dipping of panel light large area and the uniform requirement of large area bright dipping.
