Problems solved by technology
[0002] In the prior art, LED lamps on the market use PCB circuit boards, and the wires (conductive wires) for power transmission are relatively small, with small conductivity and uneven conductivity. When the power supply is not enough, the circuit board is prone to heat, resulting in serious heat accumulation, and it is easy to burn the LED wick. At the same time, the traditional LED circuit board does not have reflective functions, and its lamp installation is a soldered connection structure. It is not easy to disassemble when the parts are damaged, and it is inconvenient to repair

Embodiment 2
[0048] Embodiment two: if figure 2 As shown, the key of the LED lamp with the improved circuit board is that the reflector 9, the light-transmitting sheet 23, and the fixing ring 24 are sequentially connected.
Embodiment 3
[0049] Embodiment three: as image 3 As shown, the key of the LED lamp with improved circuit board is that the LED lamp includes a lamp cap 13 , a reflector 9 , a circuit board 7 , and a light-transmitting cover 6 . .
[0050] A method for manufacturing a circuit board of an LED lamp, the key of which is that the method includes: a metal C-shaped cylinder as the positive pole of the circuit board; an inner cylinder is arranged in the middle of the cylinder of the positive pole and an outer The cylinder acts as the negative pole of the circuit board.
[0051] The inner cylinder and the outer cylinder are integrally connected by a metal bridge.
[0052] The metal bridge passes through the opening of the C-shaped cylinder.
[0053] The space between the C-shaped cylinder, the inner cylinder and the outer cylinder is filled with insulating material; the finished product obtained in the above steps is sliced to become a circuit board that can be welded with an LED wick.

An LED lamp with an improved circuit board is characterized by comprising a light transmitting cover, the circuit board, a driving module, a reflector, a driving box, a lamp holder and a fixing ring. The light transmitting cover is connected with the reflector in a threaded mode or a buckling mode, the reflector is made of aluminum products or other metal materials, and patterns with different shapes are arranged on the surface of the reflector. The circuit board sequentially comprises a ring-shaped metal conductive positive pole, an insulation ring, a ring-shaped metal conductive negative pole and a plurality of LED lamp sources, wherein the LED lamp sources are connected between the positive pole and the negative pole, space between the positive pole and the negative pole is filled with the insulation ring, the lamp holder comprises a lamp holder cover, an upper driving cover, the driving box and a driving annular cover which are connected in sequence, and a screw fixing hole is formed in the top in the lamp holder cover. According to the LED lamp, the metal sheet positive pole, the metal sheet negative pole and transparent insulation materials are separately solidified into a whole to form the circuit board, an LED lamp filament is directly welded to the metal sheet positive pole and the metal sheet negative pole, and therefore, cooling effect of the lamp filament through the circuit board is improved remarkably. In addition, the bottom of the circuit board is coated with a coating with light reflecting effect, so that lighting and reflecting effect can be improved. By means of a connection mode of splicing fittings, leads can be connected with the splicing fittings in an insertion mode, and therefore, the circuit board or a driving power supply is maintained and replaced conveniently.
Description
Technical field: [0001] The invention belongs to LED spotlights, bulb lamps and the like in the field of lighting lamps, and specifically relates to an LED lamp with an improved circuit board. Background technique: [0002] In the prior art, LED lamps on the market use PCB circuit boards, and the wires (conductive wires) for power transmission are relatively small, with small and uneven conduction. When the power supply is not enough, the circuit board is prone to heat, resulting in serious heat accumulation, and it is easy to burn the LED wick. At the same time, the traditional LED circuit board does not have reflective functions, and its lamp installation is a soldered connection structure. When the parts are damaged, it is not easy to disassemble and repair. Invention content: [0003] In view of the defects existing in the prior art, the object of the present invention is to provide a circuit board with good heat dissipation effect and an LED lamp with an improved cir...
