Abstract
The invention discloses an internal squeezing prevention type side-emitting LED panel light. The internal squeezing prevention type side-emitting LED panel light comprises a light frame, a light guide plate and reflection paper, wherein the light guide plate and the reflection paper are arranged inside the light frame; light bar positioning profiles are arranged between the inner walls on the periphery of the light frame and the light guide plate; and LED light bars are fixed to the light bar positioning profiles. The internal squeezing prevention type side-emitting LED panel light is characterized in that buffering intervals allowing the LED light bars to drive the light bar positioning profiles to move together when squeezed by expansion of the light guide plate are reserved between the light bar positioning profiles and the inner walls of the light frame; and meanwhile, the buffering intervals are internally provided with elastic bodies allowing the light bar positioning profiles to movably reset. In the expansion process of the light guide plate, the light bar positioning profiles and the LED light bars on the light bar positioning profiles can effectively stretch out and draw back in the stressed direction, certain buffering is obtained, LEDs are prevented from hard squeezing so as to be effectively protected, the situation that the LEDs are deformed and crushed in the prior art is prevented, the service life of the side-emitting LED panel light is further prolonged, and the emitting quality of the side-emitting LED panel light is further improved.
Description
Technical field
The present invention relates to a kind of anti-internal-extrusion type side luminous
LED
Flat lamp.
Background technology
Known side is luminous
LED
The luminous component of flat lamp generally by the light guide plate being placed in lamp door, reflecting paper and
LED
Lamp bar collectively constitutes.
LED
Edge, the surrounding (typically bilateral symmetry layout) of light guide plate in lamp door is fixed and be inlaid in lamp bar by section bar.During the work of this lamp,
LED
The light sent is reflected paper reflection and the diffusion of light guide plate, is favorably improved lamplight brightness and evenness.
But above-mentioned this kind of flat lamp when real work, there are the following problems:
When
LED
The heat sent when lighting can cause light guide plate to expand, and becomes large-sized, and then on extrusion side lamp bar
LED
, due to
LED
Lamp bar is seamless rigidly fixing with lamp door inwall, and this results in
LED
By crimp by force, time serious, even broken damage, is substantially reduced service life and the luminous mass of light fixture.
Summary of the invention
The present invention seeks to: provide a kind of anti-internal-extrusion type side luminous
LED
Flat lamp, it is possible to solve side luminous
LED
Inside during flat lamp work
LED
Easily by light guide plate
The problem of extruding, prevents
LED
Deform and broken, thus it is luminous to improve side further
LED
The service life of flat lamp and luminous mass.
The technical scheme is that a kind of anti-internal-extrusion type side is luminous
LED

Further, heretofore described elastomer is silica gel or sponge cushion block.
Further, heretofore described elastomer be spring or
V
Shape shell fragment.
Further, heretofore described
LED
On lamp bar, laid out in parallel has some relative with light guide plate sidepiece
LED
, simultaneously
LED
Lamp bar is provided with and prevents
LED
The cushion pad contacted with light guide plate.It is right that the introducing of cushion pad can reduce in light guide plate expansion process further
LED
Impact and abrasion.
Further, heretofore described cushion pad is for being placed at least one
LED
On hollow cushion pad, quilt cover
LED
Contracting is at hollow cushion pad
In block, it is ensured that light guide plate will not touch
LED
。
Further, heretofore described lamp door inner bottom part arranges backboard, and backboard is provided with expanded polyethylene foam, and expanded polyethylene foam arranges described reflecting paper, and reflecting paper arranges described light guide plate.
The invention have the advantage that
1
) this flat lamp that the present invention provides, owing to leaving buffer gap between lamp bar location section bar and lamp door inwall, and elastomer is set, thus during light guide plate expands lamp bar location section bar and on
LED
Lamp bar effectively can stretch on Impact direction, it is thus achieved that certain buffering, it is to avoid
LED
By rigid extruding, thus it is effectively protected
LED
, prevent it from deforming as routine techniques and crushing, further increase side luminous
LED
The service life of flat lamp and luminous mass.
2
) present invention exists further
LED
Lamp bar is provided with and prevents
LED
The cushion pad contacted with light guide plate, it is right that the introducing of cushion pad can reduce in light guide plate expansion process further
LED
Impact and abrasion, be effectively improved the life-span of whole flat lamp.
