Two, LED panel lamp Problems existing
At present, the panel light on market is mainly divided into two classes: the illuminated panel light of direct-illumination type panel lamp and side.
Direct-illumination type panel lamp 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 light guide plate, broken the dependence to light guide plate, light fixture cost is lower, designs more flexible; 3, lightweight, after saving light guide plate, 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 the temperature residing for it is much lower, can ensure the longer life-span.Direct-illumination type panel lamp has above advantage, has following shortcoming simultaneously: the light direct beam that 1, LED sends gets off, and is sent by diffuser plate, so inevitably makes light fixture has speck; And speck will be eliminated, then need two approach: a. must strengthen the spacing of LED light source and diffuser plate, cause the thickness of light fixture to increase like this, lamp outer casing cost increases, and thickness increase simultaneously can increase the transmission path of light, 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, then has and be difficult to fixing and orientation problem.3, difficulty of dispelling the heat 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 mounting, to making to occur gap between lamp plate and postnotum, the radiating condition of lamp plate is deteriorated, and lamp pearl quantitative requirement is too much, cause power increase, increase caloric value.
Comparatively speaking, be more inclined to use now the illuminated panel light in side, direct-illumination type panel lamp power area, thickness under square one strengthen compared with the illuminated panel light in side, cannot not only cost-saving, perfectly increase lighting area but also energy-conservation.The structure of the illuminated panel light in side mainly comprises: aluminium chassis, light diffusing sheet, light guide plate, reflective sheeting, LED light source, light source substrate, power drives etc., wherein light diffusing sheet and light guide plate are the cores of the illuminated panel light in side.Side LED light is changed light angle injection by site refraction, reflection, thus is converted line source to area source by light guide plate.The light that light guide plate penetrates by light diffusing sheet more enters one deck and evenly sheds, and forms the area source of uniform light, plays a part to block site simultaneously.But existing side luminescent panel lamp only just can reach large-area exiting surface by light guide plate, and along large area more toward central light strength more weak (determine according to the light guide plate design in light guide plate, but inevitable light being along lossy during Medium Propagation); And too low to the utilization rate of the general amount of the light of LED lamp bead, easily see lamp pearl during side-looking, cause producing hot spot, between aluminium frame and exiting surface, have bright line or the inconsistent phenomenon of brightness.
Moreover, the Yuan Jian ﹐ reason that light guide plate in the illuminated panel light in side also belongs to more difficult making is to be covered with towards the one side of light source the guide-lighting picture and text that these light guiding points of Dao Guang Dian ﹐ are formed by light guide plate, and (patterns) ﹐ presents by dredging close arrangement, how to arrange these light guiding points and just can reach required briliancy and the uniformity is a large problem.Ling Wai ﹐ is in the manufacturing process of light guide plate or may occur to become Chi Qu ﹐ between the storage life this is also the large problem that restriction light guide plate uses.The preparation method of light guide plate is mainly divided into two kinds: the brush and non-printing formula of screen printing; The brush light guide plate 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 light guide plate of screen printing is to the difference of the refraction effect of light than non-printing formula; Although non-printing formula light guide plate has good light refraction effect, investment is large, the difficult grasp of production technology, needs professional equipment and production efficiency is low simultaneously.The intensity of the sheet material after its engraving can be destroyed, and wire casing and shrinkage pool easily store dust simultaneously, brings a lot of problem to production and application.
Be the LED panel lamp of a kind of free from glare of CN201120156724.7 without the such as application number of light guide plate in prior art, not only need the distance strengthening both sides LED to increase light-emitting area, and LED needs mating cavity height just can reach the effect of total reflection, however this utility model still can not meet the requirement of the bright dipping of panel light large area and large area uniform in light emission.
