Description
Technical field
The present invention relates to a kind of light fixture, particularly relate to the modular flat lamp that adopts LED or other miniature lamp bead to form.
Background technology
Existing LED flat lamp is divided into according to illumination mode: two kinds of side entering type and straight-down negative LED flat lamp.
Side entering type LED flat lamp is mainly by frame support, the diffuser plate setting gradually up and down, reflector, LGP, and a plurality of lamp bars that are oppositely arranged with the edge of LGP respectively, and drive and form.The topmost function of LGP is will be by the direction of light navigation designing, and optical material has PS polystyrene, the poly-carbonic acid vinegar of PC, PMMA (poly-methyl methacrylate vinegar) acrylic material etc.The deficiency of side entering type flat lamp is mainly: the first, and it is very high that efficiency is not allowed to be easy to do, and area more greatly is not more allowed to be easy to do.The second, weight is heavier, and price is higher.LGP is the core of side entering type flat lamp, and it is high that cost ratio straight-down negative is wanted; The 3rd, higher to LGP quality requirement, if design badly, bright in the middle of there will be, 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.The 4th, unfailing performance is relatively poor, because LGP, reflective ink and reflectance coating are in higher temperature all the time, is easy to aging yellowing, causes light emission rate to reduce, and lamp life is had a greatly reduced quality.The 5th, lamp bar arranges in opposite directions, and light source utilization rate is lower.
Straight-down negative LE D flat lamp is comprised of frame support, diffuser plate, the plane that drives, be furnished with LED particle.Straight-down negative LED flat lamp structure and side entering type are similar, just light source be evenly distributed on diffuser plate after, compare side entering type, can not do very thinly, the distance of light source and diffuser plate can not be too near, so whole lamp size is thicker, but efficiency is high more a lot of than side entering type.The main weak point of straight-down negative flat lamp is to do too thinly, between LED light source and diffuser plate, will have certain spacing, otherwise light fixture can produce bright spot, this certainly will cause the thickness of light fixture to increase, the cost of lamp outer casing is and then increased, and it is not good that the outward appearance of light fixture also can seem.And thickness increased, just increased the delivering path of light, the efficiency of light fixture is reduced.Because lamp pearl is to be fixed on postnotum, if postnotum full wafer aluminium base, cost will be very high so, if with the aluminium base of bar shaped, fixing and location etc. is again a problem.If the postnotum of straight-down negative flat lamp is used the aluminium sheet of large face, also to consider to lift for a long time the problems such as postnotum bending.
