[0002] The existing LED outdoor drive power supply is in the form of potting to achieve IP65 or higher. The potting filling mainly includes epoxy resin solid filling or silicone soft filling. Since the power supply will generate heat when it is working, the internal components of the power supply will be damaged. Thermal expansion occurs. Due to the different expansion coefficients of each device, the devices will squeeze each other when they expand, which will affect the reliability of the power supply; because the thermal conductivity of solid or soft fillers is not good, the heat of the power device cannot be dissipated effectively, thus Affect the life of the device, that is, the life of the power supply; due to the poor fluidity of the solid or soft filler during potting, it is easy to generate gaps during potting, thus affecting the waterproof performance, and it is difficult to repair after potting fails

The invention discloses a waterproof and radiating light-emitting diode (LED) drive power, relating to the field of lighting. The structural device comprises a power shell, a silicon seal, a sealing oil diaphragm, insulation heat conducting impregnation liquor, an oil diaphragm breathing hole and the like. By using the device, the sealing performance and radiating efficiency of the power are improved, thereby avoiding the damage on the circuit components of the power due to the expansion and extraction of the filling liquor, improving the reliability of the drive power, reducing the weight ofthe power itself, lowering the cost and facilitating production and maintenance, and the filling liquor can be recycled during maintenance. The device of the invention is mainly applied to LED powersand some indoor and outdoor electrical installations requiring water resistance and dust resistance.
Description
technical field [0001] The invention relates to the field of LED lighting, in particular to an LED driving power supply. Background technique [0002] The existing LED outdoor drive power supply is in the form of potting to achieve IP65 or higher. The potting filling mainly includes epoxy resin solid filling or silicone soft filling. Since the power supply will generate heat when it is working, the internal components of the power supply will be damaged. Thermal expansion occurs. Due to the different expansion coefficients of each device, the devices will squeeze each other when they expand, which will affect the reliability of the power supply; because the thermal conductivity of solid or soft fillers is not good, the heat of the power device cannot be dissipated effectively, thus It affects the life of the device, that is, the life of the power supply; due to the poor fluidity of the solid or soft filler during potting, it is easy to generate voids during potting, thus aff...
