Dodging frequency, eliminate dazzle, visual fatigue, distil visual effect；Light fixture is lightweight, easily installs, stable performance, and maintenance rate is low,
Highly versatile, saving space easy for installation；Life-span length, environmental protection；Color rendering index is high, and color reducibility is strong, optical clarity,
See that object is undistorted, be suitable for the advantages such as high-grade commercial lighting place use and progressively occur commercially.
LED flat lamp generally comprises power supply, reflectance coating, catheter plate, diffuser plate, LED lamp bar, and aluminum frame, in LED flat plate
In lamp design, light guide plate is the heart of flat lamp, and light guide plate is the high-tech product that line source is changed into area source, LED
Bar is arranged on light guide plate side, and light source is transformed into area source from straight line via the grid light guide plate and launches from light guide plate, conduit
Plate is usually acrylic material, has a certain degree of expansion during heat.The leaded light directly contacted with LED lamp bar when summer expands
Often there is to squeeze the problem of bad LED lamp bead in plate, and because circular expander is uniform, this situation typically frequently occurs in square
In LED flat lamp, the lamp bead of LED circle flat lamp can't be caused damage.
Through retrieval, having had the problem expanded with heat and contract with cold in view of light guide plate in prior art when designing LED flat lamp, China is specially
Profit application number: ZL201320118566.5, the applying date: on 03 15th, 2013, invention and created name was: LED flat lamp,
This application case discloses a kind of LED flat lamp, including shell body, LED, light guide plate and reflecting piece, described LED
Lamp is against being arranged on the first side of light guide plate, and the second side of described light guide plate is arranged on the inner side of described shell body, described reflecting piece
It is arranged on the top of described light guide plate, elastic construction is set between second side and the inner side of described shell body of described light guide plate,
The elastic deformation of described elastic construction is in the range of the expanding with heat and contract with cold of described light guide plate.This utility model light guide plate deformation time,
Its deflection is absorbed by elastic construction, does not affect fitting tightly between LED light-emitting area and light guide plate, additionally by reflecting piece
Self form elastic construction, reduce cost.Although this structure is in view of the problem of expanding with heat and contract with cold of light guide plate, but it is to solve
Light guide plate be firmly combined with problem, do not solve the problem that LED lamp bead is damaged of expanding with heat and contract with cold.
Utility model content
