Conventional light source is instead of completely in other lighting field.
Existing LED light group display light is uneven, the various complexity of work flow, and volume is big or component distribution does not conform to
Reason, has been seen long and eyes are harmful to and has been left ghost.
Therefore, it is necessary to provide a kind of new LED circuit board.
【Utility model content】
The purpose of this utility model is to provide a kind of LED circuit board with scale groove.
The technical solution of the utility model is as follows：The LED circuit board includes circuit board body and LED lamp bead, the electricity
Plate body in road includes pcb layer, insulating barrier, heat-radiating substrate and is opened in some draw-in grooves of the heat-radiating substrate, described in each
Draw-in groove bottom is provided with first groove, and the insulating barrier is embedded in first groove, and the insulating barrier offers second
Groove, the pcb layer is embedded in second groove, and the insulating barrier is by the pcb layer and the heat-radiating substrate
Interval, the LED lamp bead is embedded in the draw-in groove and is electrically connected with the pcb layer, and the side wall of the draw-in groove is circular arc
Shape.
Preferably, the insulating barrier is PP glue.
Preferably, the side wall of the draw-in groove is provided with the ink of the high reflection particle that its surface is covered in by ink jet printing.
Preferably, the heat-radiating substrate is copper coin.
Preferably, the circuit board body is several in line circuit boards, also including flexible PCB, the two adjacent electricity
Connected by flexible PCB between the pcb layer of road plate body.
Preferably, it is sequentially connected in series between the pcb layer in the same circuit board body.
The beneficial effect that the present invention is reached：Simple structure, globality is strong, can be added according to the length of circuit board body
The quantity of LED lamp bead, and by being arranged at the ink of the high reflection particle of the card groove sidewall, so that uniform light and bright
Bright, gently comfortable to eyes, illumination zone is also broader.
【Brief description of the drawings】
Fig. 1 is the cross-sectional view of the utility model LED circuit board.
【Specific embodiment】
The utility model is described in further detail with implementation method below in conjunction with the accompanying drawings.
Fig. 1 is referred to, the LED circuit board 100 includes circuit board body 1 and LED lamp bead 2, and the circuit board body 1 is wrapped
Include pcb layer 11, insulating barrier 12, heat-radiating substrate 13 and be opened in some draw-in grooves 14 of the heat-radiating substrate 13, described in each
The bottom of draw-in groove 14 is provided with first groove 15, and the insulating barrier 12 is embedded in first groove 15, the insulating barrier 12
The second groove 16 is offered, the pcb layer 11 is embedded in second groove 16, the insulating barrier 12 is by the circuit
Flaggy 11 and the heat-radiating substrate 13 are spaced, and the LED lamp bead 2 is embedded in the draw-in groove 14 and electric with the pcb layer 11
Property connection, the side wall of the draw-in groove 14 is circular arc.
The side wall of arc-shaped structure, the more conducively insertion of finger, make when the LED lamp bead 2 is mounted and dismounted, will not
The circuit board body 1 and the LED lamp bead 2 are damaged, the LED circuit board 100 is preferably protected, increased the service life.
In the present embodiment, the insulating barrier 12 is PP glue, and the PP glue can preferably by the heat-radiating substrate 13 and institute
State pcb layer 11 to be adhesively fixed, and have stability and security concurrently.
The side wall of the draw-in groove 14 is provided with the high reflection particle layer of ink 141 that its surface is covered in by ink jet printing, described
High reflection particle layer of ink 141 is the particle with high reflection, such as ceramic particle.Preferably, the particle is micron-sized or receives
Meter level, such as 0.15 μm to 0.45 μm.Layer be, for example, 5 μm to 50 μ m-thicks, more preferably 20 μm to 30 μ m-thicks.It is described high anti-
Penetrate particle layer of ink 141 and reflecting properties are also improve in blue spectral range in whole visible-range, particularly.This is being produced
It is favourable during raw white light.
The heat-radiating substrate 13 is copper coin.
Further, the circuit board body 1 is several in line circuit boards, also including flexible PCB 3, two adjacent institutes
State and connected by flexible PCB 3 between the pcb layer 11 of circuit board body 1.
It is sequentially connected in series by wire (figure depending on) between the pcb layer 11 in the same circuit board body 1.
The beneficial effect that the present invention is reached：Simple structure, globality is strong, can be added according to the length of circuit board body
The quantity of LED lamp bead, can also increase flexible PCB and connect multiple circuit board bodies, with assembled shape according to use environment
Into different structure, and by being arranged at the ink of the high reflection particle of the card groove sidewall, so that uniform light and bright,
Gently comfortable to eyes, illumination zone is also broader.
Above-described is only implementation method of the present utility model, it should be noted here that for the ordinary skill of this area
For personnel, on the premise of the utility model creation design is not departed from, improvement can also be made, but these belong to this practicality
New protection domain.
