About New Color Dimming LED PCB
The utility model relates to a novel color lamp LED circuit board, whICh comprises a substrate The surface of the base plate is provided with a  flexible circuit board lamp strip The flexible FPC light strip includes the connection of external power supply
The very white positive terminal is used to connect the white negative terminal of the negative pole of the external power supply, and is used to connect the serial module lines of the positive and negative terminals, white light source and warm light source. The invention adopts a substrate, a flexible FPClamp strip, a white light positive electrode, a white light negative electrode, a series module line, a white light source and a temperature light source, and positive and negative alternating current are input to the positive and negative electrodes. The power driver is connected to the positive and negative terminals on the circuit board respectively. It can realize double line color change, dimming and white light on the circuit board. Light A and light B can be adjusted and balanced, and the light can be controlled in sections, which solves the 3-wire input problem of the existing power driver. The installation process is SIMple and the manufacturing cost is saved.
LED is an electrical appliance used to transmit, distribute and change the light distribution of light sources, including all components required for fixing and protecting light sources (except light sources) and wiring accessories required for connecting to the power supply.
Circuit board

Especially in recent years, these lamps have been decorated in different places or have a festive atmOSPhere With the large-scale use of LED, LED lamps are favored by the public because of their energy saving, long service life and beautiful decoration This is an important part of the lamp The circuit board makes the circuit miniaturized and visualized. It plays an important role in the large-scale production of fixed circuits and the optimization of power layout
In order to achieve the purpose of color change and dimming, the power driver needs 3 lines of input in two rows of ordinary light PCB circuit boards, and it is impossible to control the lights in sections The installation process is complex and the manufacturing cost is high
In order to achieve the above purpose, the invention provides the following scientific and technological solutions: a novel color LED circuit board, including a substrate, wherein a flexible FPC light strip is set on the surface of the substrate, and the flexible FPC light strip includes connecting an external power supply. The white positive terminal of the positive pole is used to connect the white negative terminal of the negative pole of the external power supply, the serial module line used to connect the positive and negative terminals, the white light source and the temperature light source, the white positive terminal, the white negative terminal, the serial module line, and the white light source thermal light source are connected to the application module of the line LED, wherein the white light source is a single or segmented strip arranged in the application module to form at least one row of monochrome lamp beads, So as to form soft and even wiring. In the modules that can be adjusted or remain dark or change color, the warm light source is a combination of one or more color light strips arranged in at least one line of the application module to form a soft and uniform string connection. Modules that have been adjusted or are not dimmed or discolored.
Base plate is metal base plate
The metal substrate is aluminum substrate
The components welded between the circuit board and the white light source are fixed on the installation surface of the radiator by rolling, bonding or screws.
The shape of the base plate is round
Compared with the prior art, the invention has the following beneficial effects:
The invention adopts a base plate, a flexible Flexible circuit board lamp strip, a white light positive terminal, a white light negative terminal, a series of module lines, a white light source and a warm light source, and positive and negative alternating current are input from the positive and negative electrodes The power driver is connected to the positive and negative terminals on the circuit board respectively It can realize double line discoloration, darkening, and white light on the circuit board Light A and light B can be adjusted and balanced, and the light can be controlled in sections, which solves the 3-wire input problem of the existing power driver The installation process is simple and the manufacturing cost is saved
