Understand the concrete meaning of above-mentioned term in the present invention.
LED light strip, which refers to, to be assembled in LED on band-like FPC (flexible circuit board) or PCB hardboard, because its shape of product as
One strap is the same and gains the name.Because of long service life, but it is very energy saving and environmentally protective and gradually in various decoration industries
Show up prominently.Light bar has the feature that
1, soft, it can arbitrarily crimp.2, it can shear and receive.3, bulb and access are thoroughly coated flexible modeling
In glue, insulation, water-proof function are good, with insurance.4, resistance to meteorology is strong.5, it is not easy to break with, is long with longevity number.6, easily fabricated figure
The moulding such as shape, text；At the moment by wide in range using just in fabrication, bridge, approach, garden, garden, stratum, fruitless flower plate, family
All, it whitewashes and illuminates on bus, lake, the bottom, poster, small white plate for taking accounts or notes temporary, mark etc..
However existing LED light strip LED wafer 200 is placed on bracket bowl functional areas, since bowl is to LED wafer 200
Shading, thus cause 200 light emitting angle of LED wafer reduce.And 200 heat of LED wafer is diffused into branch by cradling function area
Frame pin, then light bar substrate is diffused by bracket pin, heat spreader path is longer, to influence the heat dissipation performance of light bar.
In order to overcome the above problem, provide a kind of double-deck route wide-angle light-emitting LED soft light bar in the following embodiments
10。
Fig. 1 is please referred to, Fig. 1 is a kind of light-emitting LED soft light bar 10 of double-deck route wide-angle provided in an embodiment of the present invention

Piece 200 is set up directly on flexible base board 100, and LED wafer 200 is connect at least one connection line 300.
Inventor devises a kind of light-emitting LED soft light bar 10 of double-deck route wide-angle comprising flexible base board 100 and LED
Chip 200, LED wafer 200 do not need through bracket but are set up directly on flexible base board 100, and such LED wafer 200 is sent out
Light time can emit from all angles to the maximum extent.When flexible base board 100 be it is opaque, LED wafer 200 shines can be to
180 ° of direction transmitting far from flexible base board 100；When flexible base board 100 be it is transparent, LED wafer 200 shines can not only be to
180 ° of direction transmitting far from flexible base board 100, some light can also light transmission flexible base board 100 be emitted to its back.It is so aobvious
It lands and improves the light emitting angle of LED wafer 200.
On the other hand, compared to single layer route, the set-up mode of two connection lines 300 strengthens the electricity of light bar entirety
Capacity, while the solid use of route, the hardness of light bar increase, pressure drop increases, the voltage that can be born becomes larger, and global reliability also improves
?.
In addition, the double-deck route wide-angle is light-emitting LED soft because LED wafer 200 is set up directly on flexible base board 100
200 heat of LED wafer of light bar 10 is directly diffused into light bar substrate, and heat dissipation path shortens, to promote the heat dissipation performance of light bar.
It also notes, compared to band compared with conventional base plate, the double-deck light-emitting LED soft lamp of route wide-angle is few in configuration aspects
The structures such as stiffening plate, manufacturing process also relative simplicity.
Please continue to refer to Fig. 1 to Fig. 5 to understand more CONSTRUCTED SPECIFICATIONs.
