Description
Technical field
The present invention relates to emergency-lighting set field, and in particular to a kind of guide-lighting board mounting structure.
Background technology
With the continuous progress of fire emergency lampses technology, light guide plate can preferably play LED light source light efficiency and excellent because of it
Good guide-lighting performance, is widely applied in fire-fighting emergent identification lamp.
Existing guide-lighting board mounting structure be by laser cutting technique, one end of light guide sheet cut to be formed irradiated region and
Guide-lighting paper, is then attached to light guide sheet two sides by extraction regions, then circuit board is pasted onto with glue the edge of light guide plate, finally for
Prevent the light leak from also needing to aluminium-foil paper to be attached to light guide plate surrounding.
Generated heat after LED works long hours, can melt glue, cause circuit board to depart from light guide sheet；And it is because guide-lighting
Circuit board, when assembling product is carried out, the operation difficulty of light guide sheet is pasted onto than larger, glue mistake using glue by plate than relatively thin
Many, glue can flow to light guide sheet or LED light source, influence light conductivity, and glue is very few, and circuit board patch is not tight, and circuit board easily comes off.
When being attached in light guide sheet using guide-lighting paper, covered, it is necessary to paste aluminium-foil paper to prevent light guide sheet side light leakage, but aluminium foil
Paper does not have light conductivity, so when light guide sheet is produced, to reserve the position for pasting aluminium-foil paper, causes the full-size(d) ratio of light guide sheet
Practical dimensions are big.The structure installation procedure is various, reduces production efficiency, also add product cost.
The content of the invention
In order to solve the above problems, the present invention provides a kind of guide-lighting board mounting structure, including light guide sheet, be provided with Card trough,
Irradiated region and extraction regions；Guide-lighting carton, for covering light guide sheet surface；Circuit board, configures in light guide sheet；LED light source, configuration
On circuit boards, and just to the irradiated region.
The light guide sheet forms Card trough, irradiated region and extraction regions by laser cutting in light guide sheet；The Card trough
Rectangular, size is mutually paired with the size of circuit board；The Card trough cuts to form irradiated region to light guide sheet internal direction, institute
State irradiated region and be provided with opening, just to Card trough, the shape of irradiated region is designed opening direction according to LED light source.
The circuit board is fixed in the Card trough using natural resiliency, and the LED light source is located in irradiated region.
The guide-lighting carton is folded by guide-lighting paper and formed, and the matching size pair of size and light guide sheet is divided into lid and lower cover,
After being assembled in light guide sheet, the bottom surface covering light guide plate tow sides of the upper lid and lower cover, side covering light guide plate side.
A kind of guide-lighting board mounting structure of the invention, Card trough, irradiated region and extraction regions are gone out in light guide plate internal cutting；
Using the natural resiliency of circuit board, circuit board is fixed in light guide plate, eliminating tradition will use glue fixing circuit board
Step, significantly increases production efficiency, is folded using guide-lighting paper and forms guide-lighting carton, for wrapping up light guide sheet, eliminates biography
System structure needs the reserved position for pasting aluminium-foil paper, reduces product cost, and LED light source is located in light guide plate, can make to lead
Tabula rasa light efficiency is more preferable.

Specific embodiment
Specific embodiment of the invention will be hereinafter described in reference to the drawings.
As shown in Figure 1, Figure 2, Figure 3 shows, the present invention provides a kind of guide-lighting board mounting structure, including light guide sheet 1, is provided with Card trough
11st, irradiated region 12 and extraction regions 13；Guide-lighting carton 2, for covering the surface of light guide sheet 1；Circuit board 3, configures in light guide sheet 1；
LED light source 4, configuration on circuit boards 3, and positive control penetrates area 12.
Card trough 11, irradiated region 12 and extraction regions 13 are formed in light guide sheet 1 by being cut by laser；Card trough 11 is in square
Shape, size is mutually paired with the size of circuit board 3；Card trough 11 cuts to form irradiated region 12 to the internal direction of light guide sheet 1, irradiation
Area 12 is provided with opening, and just to Card trough 11, the shape of irradiated region 12 is designed opening direction according to LED light source 4；Circuit board 3 is utilized
Natural resiliency is fixed in Card trough 11, and LED light source 4 is located in irradiated region 12；Guide-lighting carton 2 is folded by guide-lighting paper and formed, chi
The matching size pair of very little and light guide sheet 1, is divided into lid 21 and lower cover 22, after being assembled in light guide sheet 1, upper lid 21 and lower cover 22
Bottom surface covers the surface of light guide plate, the covering light guide plate side of side 23 14.
Go out Card trough 11, irradiated region 12 and extraction regions 13 in the internal cutting of light guide plate 1；Using the natural resiliency of circuit board 3, will
