The invention discloses a novel color tone light LED circuit board, comprising a substrate, the surface of the substrate is provided with a flexible FPC light bar, and the flexible FPC light bar comprises a connection for external power supply.
LEDs are appliances that transmit, distribute, and change the light distribution of a source, including all components required to secure and protect the source, except the source, and the wiring accessories necessary to connect to the power source. The lamps are decorated with various places or decorated with festive atmospheres, especially in recent years. With the large-scale use of LEDs, LED lamps are favored by the public for their advantages of energy saving, long service life and good embellishment. It is an important part of the luminaire. The circuit board makes the circuit miniaturized and intuitive, which plays an important role in mass production of fixed circuits and optimization of electrical layout.
Common lamp circuit boards In order to achieve the purpose of two-line color change and dimming, the power driver needs three line inputs, and it is not able to control the lights in sections. The installation process is complicated and the manufacturing cost is relatively high.
In order to achieve the above object, the present invention provides the following technical solution: a novel color tone light LED circuit board comprising a substrate, the surface of the substrate is provided with a flexible FPC light bar, and the flexible FPC light bar includes a connection for external power supply. a white positive terminal of the positive electrode, a white negative terminal for connecting the negative pole of the external power source, a series module line for connecting the positive terminal and the negative terminal, a white light source and a warm light source, the white positive terminal, the white negative terminal, the series module line, The white light source and the warm light source are connected into an 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 monochromatic light beads to form a soft and uniform string connection. a module that can be adjusted or not dimmed or discolored, the warm light source is a string or a plurality of color combinations of light strips arranged in at least one row in the application module to form a soft and uniform string connection. A module that is tuned or not dimmed or discolored.
- The substrate is a metal substrate
- Metal substrate is aluminum substrate
- The components welded between the circuit board and the white light source are fixed by rolling or bonding or fixed by screw on the installation surface of the radiator.
- The shape of the substrate is circular
Compared with the prior art, the beneficial effects of the present invention are as follows:
The invention adopts a substrate, a flexible FPC light bar, a white light positive terminal, a white light negative terminal, a series module wire, a white light source and a warm light source, and the positive and negative alternating currents are input from the power driver, and the circuit board is connected with the positive and negative poles. It can realize double-line color change, dimming, white light on the circuit board, A warm light B can adjust the balance, and can control the light in sections, solve the problem of the three lines input of the prior art power driver, and install The process is simple, saving manufacturing costs.
