1. Driving power supply

I believe many friends who have used LED products know that the driving power supply can be said to be the most important link in LED lighting products. A driving power supply with high efficiency, low heating and good stability is particularly important for LED lighting products, and led wall washing lamps are no exception.

The characteristics of non isolated driving power supply generally require constant current and wide voltage, that is, the municipal voltage is 85-265V, which is very common. It also requires low power consumption, high efficiency, high power factor in some cases, open circuit and short circuit protection, output overvoltage protection, high load capacity and so on, At the same time, the part involving the driving power supply should adopt some safe design and adopt the way of physical insulation, which can achieve absolute safety even when using non isolated driving power supply.

2. LED light source

In order to achieve a certain brightness, we need to pay attention to the fact that different lamp beads adopt different designs, and the heat dissipation effect is also different. Of course, the light effect is also different. It is impossible to select some low-grade and low brightness lamp beads to fill in in order to save cost. Whether the brightness of an LED wall washing lamp meets the standard depends entirely on the light source, Therefore, the light source of LED wall washing lamp is also very particular.

3. Radiator

At present, the heat dissipation structure of ordinary led wall washing lamps in the market is made of aluminum, and then the heat is directed to the external aluminum through the aluminum substrate of the lamp beads for heat dissipation. Therefore, the purity of this material determines whether the heat dissipation of an LED wall washing lamp meets the standard. If the heat dissipation material is not handled well, it will have a great impact on the service life of LED wall washing lamps, It will also affect the quality of LED wall washing lighting. Choosing a good radiator is also an aspect we should pay attention to.
