Embodiment Construction
[0017] An empty self-control heat dissipation LED power supply, including a circuit board, a power supply box body and a power supply box cover. The side wall and the bottom plate of the power box body, and the circuit board are fixedly arranged on the bottom plate of the power box body; the above-mentioned vacant units are independently and vertically arranged on the circuit board, and the working temperature of the vacant units is -40 ° C ~ 100 ° C; When the temperature of the power supply is too high, or when the humidity of the environment where the power supply is located is high, the control device is used to cut off the power supply or reduce the power of the power supply. The control device is electrically connected to the circuit board; the above-mentioned power supply box cover is U-shaped, including the top cover of the power supply box cover And the side covers symmetrically arranged at both ends of the top cover, the top cover and the side covers are provided with ...

The invention provides a vacant self-control heat-dissipation-type light-emitting diode (LED) power supply, and the vacant self-control heat-dissipation-type LED power supply mainly solves the problems that an existing vacant self-control heat-dissipation-type LED power supply is bad in heat dissipation performance and can not work in a high-temperature and high-moisture environment, adjustments which fit in with the environment can not be conducted on power supply working, and therefore the power supply is easily damaged in the prior art, and the structure is unreasonable in the prior art. The vacant self-control heat-dissipation-type LED power supply comprises a circuit board, a power supply box body and a power supply box cover, a vacant unit is independently and fixedly arranged on the circuit board, a control device is arranged on the circuit board, and the control device is electrically connected with the circuit board; the power supply box cover is in a U shape, a plurality of strip-shaped holes which are used for dissipating heat are formed in a top cover and edge covers , and an insertion type groove hole which is used for guiding a power supply wire is formed in each edge cover. Due to the adoption of the installation method of ejecting the vacant unit on the circuit board, heat is easy to dissipate, the control device is additionally-arranged, damage to the power supply is avoided, and service life of the power supply is prolonged. The power supply box cover is reasonable in arrangement of duty ratio, is high in intensity, in favor of processing and low in cost.
Description
technical field [0001] The invention relates to the field of LED lighting, in particular to an empty self-control cooling LED power supply. Background technique [0002] The existing vacant units are generally arranged on circuit boards, which is not conducive to heat dissipation and is not suitable for normal operation in high temperature and high humidity environments. [0003] The existing vacant self-control heat-dissipating LED power supply is not equipped with a control device, so that when the temperature or humidity of the power supply is too high, the power supply cannot be cut off in time, or the power supply power is reduced, causing the power supply to be damaged. [0004] The existing structure of the cover of the power supply box is relatively unreasonable, which is not conducive to heat dissipation, and may also cause sundries to fall into the power supply, thereby causing problems such as short circuit of the power supply. Contents of the invention [0005...
