technical field

The invention relates to the technical field of LED light source modules, in particular to a high-power LED multi-chip light source module.

Background technique

LED light source module is a widely used product in LED products. There are also great differences in structure and electronics. The simple one is to use a circuit board and shell equipped with LEDs to form an LED light source module. For complicated ones, add some control, constant current source and related heat dissipation treatment to make the LED life and luminous intensity better. The LED light source module is mainly used to display the night effect of advertising fonts (acrylic, blister) and logos. It uses text or logos as the medium and is installed on the top or wall of the building. It can not only show the daytime effect of the logo, but also use LED as a light source to show another effect at night.

Most of the existing LED (Light Emitting Diode, light-emitting diode) light source boards are a whole-board structure, which is costly. In addition, most of them are simple circular or strip-shaped, and the shape is monotonous, which is not conducive to product marketing. Moreover, because the whole-board light source board occupies a large volume, it also increases transportation and storage costs.

In order to solve the above problems, the Chinese invention patent with the publication number CN213453109U discloses a LED light source module with a convenient splicing shape, including at least one arc-shaped LED light source board, circuit sockets arranged at both ends of the LED light source board, at least one wire with plug terminals at both ends, and at least one return terminal. The LED light source board is provided with a plurality of LED illuminants and printed circuits electrically connected with the LED light emitters and the circuit sockets. The LED light source board can be driven by an external power supply through a circuit socket. Connect, and insert the loop terminal in another circuit socket to make the printed circuit on the LED light source board form a complete loop.

The above-mentioned LED light source module with convenient splicing shape, multiple arc-shaped LED light source boards can be connected together through a plurality of the above-mentioned wires and a complete circuit circuit is formed by inserting the circuit terminal at the end, so the circuit connection is convenient and reliable, which greatly simplifies the installation process of the connection between the LED light source boards, and the appearance is beautiful, and the shape can be diversified. A plurality of LED light source modules are combined to form a new shape or pattern, and the traditional LED light source module is not easy to change the shape and position of the LED light source module during actual use. The LED light source module of the above-mentioned convenient splicing shape is connected by electrical wires between two adjacent LED light source modules. When moving the position of the LED light source module, the electrical wires are easily damaged due to tearing, which is not conducive to use.
