Description
Technical field
The invention belongs to LED flat lamp fields, and in particular to a kind of flat lamp liner of shell convex surface domes.
Background technique
Flat lamp liner is the important devices component of flat lamp, it is between flat lamp back shroud and reflectance coating, it
Effect is that reflectance coating is tightly supported in the rear surface for being attached to light guide plate.The light that the luminous light source in side is issued, from light guide plate side
Face entering light enters light guide plate by incidence, and light is in light guide plate, and reflection, refraction, diffusing reflection of light etc. occurs, and repeatedly light becomes
Change, especially the reflection of reflectance coating, diffusing reflection the effects of under, light becomes relative to the straight to shining of flat lamp plane, from leading
The front outgoing of tabula rasa, to generate illumination functions, illuminates ambient enviroment.Traditional flat lamp gasket construction is using one piece
Or several pieces of polyethylene foam cottons, i.e. EPE pearl wool or one or a few EVA cotton.But traditional mode is there are disadvantage,
If using one or a few EPE pearl wool, microcosmic upper EPE plate face often have fluctuating tilt, therefore EPE pearl wool edge and
There can be some gaps between LED light-emitting section, be easy to appear light leakage phenomena, i.e., from the front of lamps and lanterns, after lamp is lighted, go out
On the surrounding boundary line of smooth surface, there are abnormal bright light rays.Further, since reflection film edge is pulled drawing, also it is easy to happen microcosmic
It arches upward or rises and falls, therefore be optically easy to appear water ripple phenomenon, i.e., from the front of lamps and lanterns, after lamp is lighted, in light out
In the plane in face, there is non-uniform smooth waviness phenomena.The above phenomenon is particularly easy to appear in long strip type flat lamp, such as
600x1200mm size, 300x1200mm size.
Summary of the invention
The purpose of the present invention is overcoming the prior art to have the defects that be easy to appear light leakage phenomena, a kind of flat lamp is provided and is existed
It is pressed on gasket body in structure by back shroud, the elastic bumps on gasket body can tightly compress light guide plate
In the structure of profile frame, so that light-emitting section and the always consistent dislocation-free of light guide plate center line, brightness is uniform, edge
The flat lamp of the shell convex surface domes of no light leakage pads.
The technical solution adopted by the present invention to solve the technical problems is: a kind of flat lamp of shell convex surface domes
Liner comprising gasket body is evenly equipped with multiple elastic bumps in the plate face of gasket body, and each elastic bumps are in gasket body
Height in plate face is equal.
In LED flat lamp of the invention, flat lamp compresses gasket body by back shroud in structure, on gasket body
Elastic bumps light guide plate can be tightly pressed in the structure of profile frame so that light-emitting section and light guide plate center line
Always consistent dislocation-free, brightness is uniform, and edge is without light leakage, to solve dislocation bring leakage problem.After in addition,
Reflectance coating is pressed on light guide plate surface by the elastic bumps on gasket body by cover board securely.Since elastic bumps uniformly dissipate
Cloth arrangement allows each elastic bumps respectively to put forth effort uniformly, to compress reflectance coating, is pressed against by elasticity, and reflectance coating will not be sent out
Life is microcosmic to arch upward or rising and falling, to solve the water ripples large area problem, guarantees that smooth surface is uniformly beautiful.From lamps and lanterns
Front observation, is not in non-uniform smooth waviness phenomena, uniform illumination in the plane of light-emitting surface after lamp is lighted.
Similarly, on the contrary, the elastic bumps on gasket body can also be pressed against the technical effect phase played on the cover board
Together.
Further, each elastic bumps are hollow convex block, and elasticity is good, while saving the material of gasket body.
Further, each elastic bumps are further to save in shelly-shaped groove structure is taken out at the back side of gasket body
The material of gasket body.Meanwhile such structure formation is shell convex surface domes, thus generate biggish resistance to compression
Ability, it is not easy to the generation of salient point collapse phenomenon occur, to ensure that the long-term uniformity of flat lamp illumination picture.
Further, elastic bumps are the plastics or rubber of plastic uptake shell, or the metal of shell, manufacturer are taken out for punching press
Just, processing cost is low.
Preferably, elastic bumps are in cube-shaped, rectangular-shape, positive quadrangular frustum pyramid shaped or positive hexagonal column, and top surface side length
Angle with the side length lines of gasket body is 0 ° -90 °；It, can be according to the cost of processing mold suitable for not having to the flat lamp of specification
With the active force for being pressed against light guide plate and reflectance coating, the shape for rationally designing elastic bumps is carried out.Wherein, the elasticity of positive quadrangular frustum pyramid shaped
Raised inclined ramp can also be in 0 ° -90 ° with the plane included angle of gasket body.
Similarly, elastic bumps are in cylindrical shape and hemisphere shape.
Further, elastic bumps are uniformly distributed in matrix in the plate face of gasket body, facilitate manufacture, compress uniform force.
Preferably, height of the elastic bumps in the plate face of gasket body is 2-8mm, the plate suitable for different-thickness
Lamp can be used for thickness filled layer.
Preferably, the spacing of two elastic bumps of arbitrary neighborhood is 2-20mm；Suitable for different length or width
Flat lamp.
Preferably, elastic bumps are parallel to the end face length of the plate face of gasket body or diameter is 4-100mm, can also fit
It is applied widely for the flat lamp of different length or width.
A kind of beneficial effect of the flat lamp liner of shell convex surface domes of the invention is:
1. flat lamp compresses gasket body by back shroud in structure, the elastic bumps on gasket body can be leading
Tabula rasa is tightly pressed in the structure of profile frame, so that light-emitting section and the always consistent dislocation-free of light guide plate center line,
Brightness is uniform, and edge is without light leakage, to solve dislocation bring leakage problem；
2. reflectance coating is pressed on light guide plate surface by the elastic bumps on gasket body by back shroud securely；Due to bullet
Property protrusion uniformly dispersing arrangement, allow each elastic bumps respectively to put forth effort uniformly, to compress reflectance coating, by elasticity be pressed against,
Reflectance coating will not occur it is microcosmic arching upward or rising and falling, to solve the water ripples large area problem, guarantee that smooth surface is uniform
It is beautiful.It is not in non-uniform smooth waviness phenomena, light in the plane of light-emitting surface after lamp is lighted from the front of lamps and lanterns
According to uniform.
