Embodiment Construction
[0013] An empty heat-dissipating LED power supply, including a circuit board, a power supply box body and a power supply box cover. The above-mentioned circuit board is fixedly arranged in the power supply box body. The wall and the bottom plate of the power box body, the circuit board is fixedly arranged on the bottom plate of the power box body; the above-mentioned vacant unit is independently and vertically installed on the circuit board, and the working temperature of the vacant unit is -40 ° C ~ 100 ° C; the above-mentioned power box cover is U-shaped, It includes the top cover of the power box cover and the side covers symmetrically arranged at both ends of the top cover. The above-mentioned top cover and side covers are provided with a plurality of strip holes for heat dissipation, and the side cover is also provided with plug-in slots for leading out power lines. hole; the width of the above-mentioned strip-shaped hole is less than 3mm; the total area of the above-men...

The invention provides a vacant heat dissipation type light-emitting diode (LED) power supply, and the vacant heat dissipation type LED power supply mainly solves the problems that the existing vacancy heat dissipation type LED power supply is bad in heat dissipation performance and can not work in a high-temperature and high-moisture environment, and an existing technical structure is not reasonable. The vacancy heat dissipation type LED power supply comprises a circuit board, a power supply box body and a power supply box cover, a vacancy unit is independently and vertically arranged on the circuit board, the power supply box cover is in a U shape and comprises a top cover of the power supply box cover and edge covers which are symmetrically arranged at two ends of the top cover, a plurality of strip-shaped holes which are used for dissipating heat are formed in both the top cover and the 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 vacant unit can be independently changed, the vacancy heat dissipation type LED power supply can be suitable for the high-temperature and high-moisture environment, an air duct is formed by vertically arranging the vacancy unit, heat can be easily taken through air flow circulation, and heat dissipation effect is further improved. The power supply box cover is reasonable in duty ratio, high in intensity, in favor of manufacturing and low in cost.
Description
technical field [0001] The invention relates to the field of LED lighting, in particular to an empty cooling type LED power supply. Background technique [0002] The vacant unit of the existing LED power supply is generally arranged on the circuit board, which is not conducive to heat dissipation, and is not suitable for normal operation in a high temperature and high humidity environment. [0003] 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 [0004] The invention provides a vacant heat-dissipating LED power supply, which mainly solves the problems that the existing vacant heat-dissipating LED power supply has poor heat dissipation performance and cannot work in a high-temperature and high-humidity environment; the structure of the prio...
