Embodiment Construction

[0028] The content of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0029] Such as figure 2 As shown, the schematic diagram of a single finger LED BAR.

[0030] 2 cables are connected to the VCC and GND of the power supply module PSU, and the voltage is connected to the PCB.

[0031] The anodes of LED11, LED21, and LED31 of the first horizontal aluminum substrate are connected to VCC, and the cathodes of LED1N, LED2N, and LED3N are connected to GND. LED11, LED12, and LED1N are connected in series to form one string, LED21, LED22, and LED2N are connected in series to form one string, and LED31, LED32, and LED3N are connected in series to form one string.

[0032] The anodes of LED11, LED21, and LED31 of the second horizontal aluminum substrate are connected to VCC through a jumper 0Ω resistor, and the cathodes of LED1N, LED2N, and LED3N are connected to GND. LED11, LED12, and LED1N are connected in serie...

Abstract

The invention relates to a design and a manufacturing method of an inserted aluminum substrate, in particular to a method for designing an inserted LED BAR. A plurality of parallel LED BARs are transversely designed; connecting leads of LED BARs are mutually connected on a longitudinal aluminum substrate to be combined into a unified wiring port and the unified wiring port is connected with a power supply module and a control module; and connecting wire jumpers needed by the plurality of leads on the longitudinal aluminum substrate are connected through a resistor of 0 ohm. Multi-layer inserted design is performed by using a flexible printed circuit (FPC), a certain length is reserved between the wiring ports, the insertion is facilitated, and the reliability is improved.

Description

Technical field [0001] The invention relates to the design and manufacture of circuit boards and the field of LED applications, in particular to the design and manufacture of a finger-type LED BAR, and the related control technology in the LED application field with complex functions. Background technique [0002] At present, LED is the main product of green energy-saving lighting. Because LED is an electric and point light source, it is small in size, pollution-free, and easy to apply, and it has received widespread attention. [0003] In the application field, LEDs are mainly mounted on aluminum substrates, especially high-power LED applications, especially high-grade aluminum substrates as the preferred chip carrier. [0004] Such as figure 1 As shown, take three aluminum substrates, three parallel arrays of three LED strings on each aluminum substrate, and N devices in series for each string of LEDs as an example. The connection relationship is: [0005] Cable 1, cable 3, and cab...
