Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of light sources, in particular to a light source that can be connected in series. Background Art
[0002] In lighting technology, LED filaments, with their unique high luminous efficiency, high color rendering, and low energy consumption, have become a hot topic of research within the industry. Currently, LED filament light sources are primarily connected in series. However, when a large number of LED chips are connected in series, the required supply voltage is relatively high. Existing methods for connecting LED filaments in parallel include connecting the electrodes of the LED chips with a brushed metal layer, and placing wires inside the LED circuit board and connecting them with a brushed metal layer. However, the reflective properties of metal can affect the light source quality. Using circuit board wiring is costly, complex, and requires a single supply voltage, making it difficult to adapt to various low-voltage power supply environments.
[0003] In the related art, a solution for a resistor-free low-voltage LED light strip (Announcement No.: CN209839769U) was discovered after searching. The multiple LEDs and constant current chips are connected in series to form LED series units. Multiple LED series units are connected in parallel to the positive and negative power supply lines. The operating voltage of the LED series units is 24V. A low-power constant current chip is used to suppress surges, and no high-power resistors are required. Each LED series unit has low power consumption. The same power supply can drive more LED series units, and the light strip can be extended.
[0004] However, the aforementioned method of placing wires on a flexible circuit board and securing the LEDs in series first and then in parallel can render the entire series circuit inoperable if a single LED in the series circuit fails or stops functioning. Furthermore, series connections can result in excessive filament voltage, making them unsuitable for low-voltage circuits. To address this issue, we have developed a light source that can be connected in series. Utility Model Content

When each power line A is connected in series, there are ten in series. If the light source body of the fifth one burns out on the surface of the aluminum substrate, it will not affect the lighting of other light sources on the surface of the aluminum substrate. It can be achieved that if one of the power lines A burns out, the damaged power line A can be replaced separately.
[0014] The terminals A and B on the surfaces of both ends of the aluminum substrate are connected in series to power. There is a set of 220V power lines on the aluminum substrate.
