A kind of LED daylight lamp circuit plate, comprise two flat conductors that are arranged in parallel, be respectively flat conductor a and flat conductor b, be bonded in the bearing bed on the described flat conductor back side, cover described flat conductor positive and expose the multiple row solder joint to 1 insulating barrier, two solder joints of each solder joint centering are welded on respectively on flat conductor a and flat conductor b, every row solder joint between be in parallel, described two flat conductors every seven row solder joints between be disconnected, after disconnecting, at incision position flat conductor b and flat conductor a, be cross-linked, thereby form two otch two flat conductor both sides, make every seven row solder joints between form series connection.Because flat conductor self has resistance, every seven row solder joints between form series connection, can make every seven row solder joints between resistance consistent.
As preferably, also be provided with copper foil layer between described flat conductor and bearing bed, copper foil layer one end and bearing bed flush, and are reserved with a breach between the copper foil layer other end and bearing bed.Its purpose is, prevents that the arcing phenomenon from appearring in the LED fluorescent lamp when energising.
As preferably, described LED daylight lamp circuit plate is strip, and the positive pole of circuit is positioned at an end of circuit board, and negative pole is positioned at the other end of circuit board.Its purpose is, first, when mounted, be beneficial to the splicing between circuit board and circuit board.The second, be positioned at the two ends of circuit board due to the both positive and negative polarity of circuit board, make each the LED lamp pearl on circuit board identical through the length of circuit board, each LED lamp pearl has identical resistance, makes the brightness uniformity at fluorescent lamp two ends.
As preferably, described two flat conductors are positioned at the central authorities of circuit board, and the width of flat conductor is designated as A, and the flat conductor outward flange is designated as B, A ︰ B=2 ︰ 3～3 ︰ 4 to the distance of board edge.A ︰ B=1 ︰ 1～2 ︰ 1 of existing LED circuit plate, this makes in the situation that the flat conductor width is consistent, flat conductor outward flange of the present utility model, to the distance much larger than prior art apart from B of board edge, can effectively prevent the appearance of arcing phenomenon, to improve security performance.
As preferably, the length of described LED daylight lamp circuit plate is 20cm～30cm, and every two blocks of LED daylight lamp circuit plates are by connecting at the bonding insulating tape of bearing bed.The LED daylight lamp circuit plate of disconnected shape can be spliced when mounted, is convenient for carrying installation.
As preferably, the right width of described solder joint is 1mm～2mm, is highly 2mm～3mm.In prior art, the right width of electric welding is generally 0.5mm, is highly 1mm, makes area of dissipation less, and radiating effect is undesirable, increases its width and height, to guarantee its heat dispersion, improves quality.
As preferably, the bearing of trend of described flat conductor, bearing bed, insulating barrier is that laterally described solder joint is to being longitudinal arrangement.
In sum, the beneficial effects of the utility model are: the utility model is disconnected shape form, has changed the form of a formula of original circuit board, and the convenience on installation is carried has improved greatly.The resistance of each LED lamp pearl on circuit board is consistent, does not have voltage difference, makes the brightness uniformity at LED fluorescent lamp two ends.The right area of electric welding increases, and has increased its heat dispersion.Flat conductor increases to the distance of board edge, increases its security performance.
