Abstract
The utility model provides a vacant spacing automatically-controlled type LED power supply, which mainly solves the problems that the traditional vacant spacing automatically-controlled type LED power supply is poor in heat dissipation property and is incapable of working in high-temperature and high-humidity environments, the prior art is incapable of making adjustment suitable for environment on working of the power supply to cause that the power supply is easy to be damaged and the circuit board of the traditional vacant spacing automatically-controlled type LED power supply is unreasonable to set and inconvenient to install and maintain. The vacant spacing automatically-controlled type LED power supply comprises a circuit board, a power box body and a power box cover, wherein vacant units are independently and vertically arranged on the circuit board, a control device is arranged on the circuit board, and a bottom plate of the power box body is provided with at least three groups of connecting holes. According to the utility model, due to adoption of an installation mode that the vacant units are vertically arranged on the circuit board, easy heat-dissipation is achieved; and because the control device is additionally arranged, the power supply is prevented from being damaged, and the service life of the power supply is prolonged. A gap is formed between the circuit board and the bottom plate of the power box body and can be used as an air channel, formation of airflow is facilitated, and therefore the vacant spacing automatically-controlled type LED power supply is more convenient to install and maintain.
