Description

Technical Field

[0001] This utility model relates to circuit controllers, and in particular to a light strip driver for controlling the operation of light strips. Background Technology

[0002] Compared to light bulbs, LED strips offer greater versatility and can create a wider variety of lighting effects. To control operating current and voltage, ensure safe circuit operation, and guarantee the normal functioning of LEDs, LED strips typically require a strip driver to connect to the circuit. Furthermore, to achieve specific lighting effects, the strip driver often needs to connect multiple strips simultaneously, allowing them to work in tandem. However, the use of multiple strips, and the numerous LEDs on each strip, inevitably increases the power consumption of the strip driver, generating significant heat during operation. To dissipate this heat quickly, existing strip drivers use metal materials for their housings, which not only increases the driver's weight and production costs but also obstructs wireless signal transmission due to electromagnetic shielding effects, weakening the signal and hindering its use in modern smart homes. Utility Model Content

[0003] The purpose of this invention is to provide a novel LED strip driver that reduces weight and production costs while ensuring heat dissipation efficiency and minimizing the weakening of wireless transmission signals.

[0004] The LED strip driver of this utility model includes a base box made of plastic material with an opening on one side, and a heat sink made of metal that can cover the opening side of the base box; a circuit board is installed inside the base box, and thermal silicone is provided between the circuit board and the inner side of the heat sink, and the two sides of the thermal silicone are in contact with the power resistors on the heat sink and the circuit board, respectively.

[0005] The LED strip driver of this invention features a plastic housing as its base, inside which a circuit board, wireless transmission module, and other electronic components are installed. The circuit board is positioned close to the opening side, and a metal heat sink covers the opening of the base, forming a complete outer shell. This shell structure effectively reduces electromagnetic shielding effects, minimizes attenuation of the wireless signal, and thus improves the strength of the wireless transmission signal, making it better suited for modern smart homes. Furthermore, the heat generated by the circuit board and electronic components during operation is mainly concentrated in the power resistor. This heat can be quickly transferred to the heat sink via thermal silicone, and then rapidly dissipated by the heat sink, ensuring adequate cooling. Therefore, the LED strip driver not only effectively ensures rapid heat dissipation and stable LED strip operation but also reduces weight and production costs while improving the strength and stability of wireless transmission.

[0006] Preferably, the bottom box has an opening at the top, and the heat sink is connected to the opening at the top of the bottom box.

[0007] Preferably, the heat sink has several heat dissipation fins arranged in parallel.

[0008] Preferably, the heat sink is connected to the top of the base box, and the heat sink fins are arranged vertically side by side.

[0009] Preferably, the inner side of the bottom box is provided with several limiting blocks near the opening, and the heat dissipation plate is provided with a hook plate. The end of the hook plate is a hook that engages and fixes with the limiting blocks. The heat dissipation plate is connected and fixed to the limiting blocks on the bottom box through the hook plate and the hook on it.

[0010] Preferably, the power resistor is located in the middle of the circuit board.

[0011] Preferably, the bottom box is equipped with several wiring ports.

[0012] By configuring the LED strip driver as described above, the heat dissipation efficiency of the driver can be further improved, and the ease of installation and removal of the heat sink can be enhanced. Attached Figure Description

If the specific posture changes, the directional indication will also change accordingly.

[0018] If the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.

[0019] This utility model proposes a light strip driver.

[0020] The LED strip driver of this embodiment includes a base box 1 with an opening on one side and a heat sink 2 that can cover the opening side of the base box. The base box is made of plastic material, the heat sink is made of metal, and a circuit board 3 is installed inside the base box. Thermal silicone 4 is provided between the circuit board and the inner side of the heat sink, and the two sides of the thermal silicone are in contact with the power resistors 5 on the heat sink and the circuit board, respectively.

[0021] like Figure 1-3 As shown, the base box is a plastic shell with several wiring ports 6, through which circuits and light strips are connected. The interior of the base box houses the circuit board, wireless transmission module, and other electronic components. The circuit board is positioned close to the opening, while a metal heat sink covers the opening and connects to the base box to form a complete outer shell. This shell structure effectively reduces electromagnetic shielding effects, minimizes attenuation of wireless signals, and thus improves the strength of wireless transmission signals, making it better suited for modern smart homes. Furthermore, the heat generated by the circuit board and electronic components during operation is mainly concentrated in the power resistor. The heat from the power resistor can be quickly transferred to the heat sink via thermal silicone, and then rapidly dissipated by the heat sink, ensuring adequate cooling.

[0022] The aforementioned LED strip driver has an opening at the top of the base box 1, and a heat sink 2 is connected to the opening at the top of the base box. This is because heat is more easily transferred upwards, and placing the heat sink at the top also provides higher heat dissipation efficiency. Furthermore, the heat sink 2, specifically at its top, has several vertically arranged heat dissipation fins 21, further improving heat dissipation efficiency.

[0023] like Figure 2As shown, the inner side of the bottom box 1 is provided with several limiting blocks 11 near the opening, and the heat dissipation plate 2 is provided with a hook plate 22. The end of the hook plate is a hook 23 that engages and is fixed with the limiting blocks. The heat dissipation plate is connected and fixed to the limiting blocks on the bottom box through the hook plate and the hook on it. Its structure is simple, its operation is stable and its assembly and disassembly are convenient, which can improve the convenience of production and maintenance.

[0024] like Figure 2 As shown, the power resistor 5 is located in the middle of the circuit board 3, which allows the thermal silicone to adhere to the middle of the inner side of the heat sink, making the heat of the heat sink more even and improving the heat dissipation efficiency.

[0025] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
