Description

Lamp strip driver Technical Field The present utility model relates to circuit controllers, and more particularly to a lamp strip driver for controlling the operation of a lamp strip. Background The ribbon lamp has higher applicability than a bulb, and can form more diversified lighting atmosphere effects. In order to control the working current and voltage, the safe operation of the circuit is ensured, the normal operation of the LED lamp is ensured, and the lamp strip is generally connected into the circuit through a lamp strip driver. Meanwhile, in order to form a specific light effect, the lamp strip driver also needs to connect a plurality of lamp strips at the same time, so that the lamp strips work in a matched mode. However, on the other hand, the use of multiple light strips, and multiple LED light beads on each strip, necessarily increases the power of the strip driver, which generates a significant amount of heat during operation. In order to dissipate the heat as soon as possible, the existing lamp strip driver adopts a metal material which is more favorable for heat dissipation to manufacture the shell of the driver, but the weight of the driver can be increased, the production cost can be increased, wireless transmission signals can be blocked due to electromagnetic shielding effect, the wireless transmission signals are weakened, and the use of modern intelligent home is not facilitated. Disclosure of utility model The utility model aims to provide a novel lamp belt driver, which can reduce weight and production cost and reduce weakening of wireless transmission signals while ensuring heat dissipation efficiency. The lamp belt driver comprises a bottom box which is made of plastic materials and is provided with an opening at one side, a heat radiation plate which is made of metal and can cover the opening side of the bottom box, a circuit board is arranged in the bottom box, heat radiation silica gel is arranged between the circuit board and the inner side of the heat radiation plate, and two sides of the heat radiation silica gel are respectively contacted with the heat radiation plate and a power resistor on the circuit board. The bottom box of the lamp belt driver is a plastic shell, a circuit board, a wireless transmission module and other electronic elements are arranged in the bottom box, the circuit board is arranged near the opening side, the radiating plate made of metal covers the opening of the bottom box and is connected with the bottom box to form a complete shell, and the shell with the structure can effectively reduce electromagnetic shielding effect and reduce weakening of wireless signals, so that the strength of the wireless transmission signals is improved, and the lamp belt driver is better suitable for modern intelligent households. On the other hand, the heat generated in the working process of the circuit board and the electronic element in the bottom box is mainly concentrated on the power resistor, and the heat of the power resistor can be quickly transferred to the radiating plate through the radiating silica gel and then quickly radiated through the radiating plate, so that the radiating requirement is ensured. Therefore, the lamp strip driver not only can effectively ensure the heat dissipation speed and the working stability of the LED lamp strip, but also can reduce the weight and the production cost and improve the strength and the stability of wireless transmission. Preferably, the top opening of the bottom box is arranged, and the heat dissipation plate is connected to the opening at the top of the bottom box.
