Description
Technical field
The present invention relates to lighting technical field, particularly relate to a kind of luminescence component and plate mat lamp thereof.
Background technology
LED (LightEmittingDiode, light emitting diode) technology with its power saving, brightness is high, long service life, anti-seismic performance are good etc., and advantage is extensively promoted, the application of LED in normal lighting and display is in recent years more and more extensive.
At present, existing LED illumination mode mainly comprises straight-down negative and side entering type two kinds.Wherein, adopt the LED lamp panel of straight-down negative luminescence to be to arrange in array-like in a lampshade multiple LED lamp holder, and corresponding drive circuit is set in lampshade, this simple and practical, it has following advantage: first, efficiency is high, and the light of LED through diffuser plate direct irradiation out, improves the system energy efficiency of light fixture; The second, cost is lower, saves the cost of light guide plate, and the cost of light fixture is reduced, and inner space is large, designs also more flexible; 3rd, light fitting quality alleviates, because eliminate light guide plate; 4th, reliability increases.But the main weak point of straight-down negative LED lamp panel is to do too thin, will have certain spacing between LED light source and diffuser plate, otherwise light fixture can produce bright spot, this certainly will cause the thickness of light fixture to increase, and the cost of lamp outer casing is and then increased, and the outward appearance of light fixture also can seem not good.And thickness adds, just increase the delivering path of light, the efficiency of light fixture is reduced.Because lamp pearl is fixed on postnotum, if postnotum full wafer aluminium base, so cost will be very high, if with the aluminium base of bar shaped, fixing and location etc. is again a problem.If the postnotum of direct type flat plate light uses the aluminium sheet in large face, also to consider to lift the problems such as postnotum bending for a long time; More dazzling during straight-down negative LED lamp panel work simultaneously, the uniform light degree sent is not good, and its uniformity is specifically less than 70%.
Be appreciated that in Design of Luminaires, the performance of each components and parts and material therefor will determine the performance of light fixture product, and element increases, and unfailing performance reduces.If so the good diffuser plate of service property (quality), light fixture can ensure the longer life-span, and light guide plate and reflectance coating are at high temperature, easy aging yellowing, affect light extraction efficiency and service life.The flat lamp of the side entering type luminescence parts that are plane and the inside that are square are adopted also to be all plane, the mainly reflecting plate of mounting plane shape, light guide plate and diffuser plate successively in a rectangular base, and in base and at the side edge mounted LED lamp bar of light guide plate, light reaches the object improving the uniformity under the acting in conjunction of reflecting plate and light guide plate through multiple reflections, and effectively prevents dazzle by diffuser plate.From said structure and principle, the core of the illuminated LED planar lamp in such side is, by the effect of light guide plate, line source is converted into area source.
By the structure of above-mentioned prior art light guide plate and principle known, light on the light guide plate of prior art is all that this mode being covered with surrounding luminescence by LED lamp bar could realize, this technique is very difficult in practical operation, and yield is lower, and therefore cost is high; The illuminated LED planar lamp in this side has following deficiency simultaneously: first, it is very high that efficiency is not allowed to be easy to do, and area is not more allowed to be easy to do more greatly, under equal-wattage, side entering type LED flat lamp still has no small gap in the performance indications such as light output, efficiency and colour rendering index compared with traditional LED down; The second, heavier-weight, price is higher.Light guide plate is the core of side entering type flat lamp; Because adding light guide plate, cost ratio straight-down negative wants high; 3rd, higher to light guide plate quality requirement, if design bad, there will be middle bright, both sides are dark, or enter plain edge and have bright border, or the phenomenon such as different angles brightness is inconsistent, affect lighting quality; 4th, unfailing performance is relatively poor is in higher temperature all the time due to the light guide plate in the light emitting plane lamp of side, reflective ink and reflectance coating, and be easy to aging yellowing, cause light emission rate to reduce, lamp life is had a greatly reduced quality.
Summary of the invention
