The flexible light-emitting diode light strip adopts a PCB soft board as a main board, and is generally assembled by using a chip type LED. Depending on the application type, the number and length of LEDs can be adjusted freely. Moreover, it can be bent freely based on its use of a PCB flexible board; therefore, the flexible light-emitting diode light strip is suitable for use in an irregular shape or a narrow space.

The power supply unit is electrically connected to the conductive unit to provide a power to each of the light emitting diode units. Wherein, each of the conductive units and the corresponding light-emitting diode unit has an electrical connection region, which is selectively disconnected or connected, thereby turning off or turning on the light emitted by each of the light-emitting diode units, so that the light is emitted The diode can be discolored by a single color or mixed light.

In the above-mentioned pivot-adjustable color-changing light-emitting diode device, the flexible substrate may be in the form of a strip or a repeating connection, which may be composed of a flexible printed circuit (FPC).

In the above-mentioned color-controlled light-emitting diode device based on the pivotal control, the light emitted by each of the light-emitting diode units includes a red light, a green light or a blue light; and the light emitted by each light-emitting diode can be Blending light to form a yellow light, a cyan light, a magenta light (Magenta) or a white light.

The number of the light emitting diode unit 140 and the conductive unit 130 is not particularly limited. In FIG. 1 , the overall color-controlled light-emitting diode device 100 based on the pivot control includes three conductive units 130 and three light-emitting diode units 140 . Each of the conductive units 130 is electrically connected to each of the light emitting diode units 140. The three light emitting diode units 140 can emit red light, green light, and blue light, respectively. Each of the conductive units 130 and each of the LED units 140 has an electrical connection region 180. The electrical connection region 180 can be selectively disconnected or connected to control whether each of the conductive units 130 and its corresponding LED unit 140 are turned on or not, thereby controlling whether each of the LED units 140 is illuminated or not. For example, in FIG. 1 , when the electrical connection region 180 between the light emitting diode unit 140 emitting red light and the corresponding conductive unit 130 is disconnected, only the blue light and the green light emitting diode are emitted. The body unit 140 can be turned on and lit. At this time, based on the principle of hue, the color of the color-changing light-emitting diode device 100 based on the pivot control is cyan light formed by blue light and green light mixed light. Based on this principle, the LED unit 140 of any number and of any color can be turned on or off to form a variety of mixed light colors. Since the light-emitting diode unit 140 including at least three kinds of light colors of red light, green light, and blue light is used, the entire color-adjustable light-emitting diode device 100 based on the pivotal control may include at least red light according to the opening and closing state thereof. , green light, blue light, yellow light, cyan light, magenta light (Magenta) and white light color combination.

The opening cover 150 is formed on the flexible substrate 110. When the opening cover 150 is opened or removed, the conductive unit 130 at the position opposite to the opening cover 150 is disconnected, so that power cannot be supplied to the corresponding light emitting diode. The unit 140; when the aperture cover 150 is closed or installed, the conductive unit 130 is connected to provide power to the corresponding light-emitting diode unit 140. Thereby, the dimming effect can be achieved in a simple manner, without the need for the LED strip lamp to be dimmed using a high-cost driving IC.

The switching device 160 can control each conductive unit 130 and its corresponding LED. Units 140 are turned on or off. For example, when the switch device 160 is pressed, the corresponding LED unit 140 can be illuminated, and the LED unit 140 that controls different light colors can be separately illuminated or mixed to obtain a dimming effect.

Similar to the foregoing embodiment, as shown in FIG. 4, the flexible substrate 110 may be repeatedly extended to form an elongated strip.
