[0003] At present, the heat dissipation of LED street lamps mainly depends on natural heat dissipation, that is, the air convection on the heat dissipation holes on the lamp housing is used to take away heat, the heat dissipation effect is not ideal, and the service life of LED street lamps is affected.
Therefore, it can be seen from the above description that the power supply device in the prior art has low operational reliability, poor power supply stability, and poor heat dissipation effect

The invention discloses a water-cooled LED streetlamp comprising a cooling water tank, an LED chip, a heat transfer device, a water pump, and a radiator. The water-cooled LED streetlamp is characterized in that the cooling water tank is connected with the water pump through a first water pipe, the water pump is connected with the heat transfer device through a second water pipe, the heat transfer device is connected with the radiator through a third water pipe, the radiator is connected with the cooling water tank through a fourth water pipe, a temperature sensor is disposed inside each of the cooling water tank and the heat transfer device, and the temperature sensors are electrically connected with the radiator and the water pump. The cooling water is used as a medium to transfer heat; a single-chip microcomputer is used for automatic control; accordingly the streetlamp has the radiating effect which is not matched by that of air cooling and natural cooling; the water-cooled LED streetlamp is especially suitable for high-power LED chips and is good in radiating effect and long in service life.
Description
technical field [0001] The invention belongs to the field of LED lamps, and in particular relates to a water-cooled LED street lamp. Background technique [0002] At present, LED lighting products are gradually replacing traditional lighting fixtures as mainstream lighting products. For high-power LED street lamps, the luminous efficiency is the key factor, but the heat dissipation of LED lamps is a crucial factor to achieve long life and high luminous efficiency. In reality, there are many reports of early failure of street lights, called dead lights, which is a great constraint for public lighting. [0003] At present, the heat dissipation of LED street lamps mainly relies on natural heat dissipation, that is, the air convection on the heat dissipation holes on the lamp housing is used to take away heat. The heat dissipation effect is not ideal, which affects the service life of LED street lamps. Therefore, it can be seen from the above description that the power supply ...
