Description

Outdoor LED Driver

Technical field:

The utility model relates to the technical field of power supply products, in particular to an outdoor LED driving power supply with waterproof effect.

Background technique:

Due to the advantages of energy saving and environmental protection of LED lighting fixtures, many outdoor lighting fixtures are currently replaced with LED lighting fixtures. LED lamps cannot be directly connected to the mains, and require a driving power supply to convert the inputted mains to form a power supply for LED lighting. For ordinary LED drive power, in order to ensure the normal operation of LED lamps, it must have a good heat dissipation effect to dissipate the heat in the power supply in time. For the driving power supply working outdoors, it not only needs to ensure a good heat dissipation effect, but also needs to have a waterproof effect, so as to prevent outdoor rainwater from entering the power supply, causing a short circuit of the power supply, and burning the power supply. Taking the outdoor LED street lamp power supply as an example, the current structural method is: install the circuit board of the power supply in a box, and then pour silica gel into the box, so that the circuit board and the box form a whole. Although this method can achieve the effects of waterproofing and heat dissipation, it also has the following disadvantages:

1. The cost is high. Due to the high price of silica gel raw materials, pouring silica gel into the power supply can have a good heat dissipation effect, but it also leads to high product costs.

2. Difficult to repair, because the circuit board is encapsulated in the power supply box through silica gel, the box body and the circuit board form a whole that cannot be disassembled. If there is a problem with the circuit in the circuit board, it cannot be repaired at all, and the entire power supply can only be scrapped , which causes huge waste and is not conducive to environmental protection.

3. The production process is complicated. Because the current production method needs to be filled with silica gel, the production process is increased and the production efficiency is reduced.

The inventor once proposed a Chinese utility model patent for LED driving power to solve the defects of the existing technology, but this LED driving power still needs to be improved. This outdoor LED driving power is currently mainly used for LED lighting fixtures In actual use, it is often necessary to adjust parameters such as the brightness of the LED lighting source through the adjustment knob in the power supply. However, in the technical solution proposed by the inventor, the shell is fully sealed for waterproof effect. Open any holes, so it is impossible to adjust directly from the outside, and the power supply case must be opened to adjust, which will cause great trouble to the user.
