LED wall washer, as the name suggests, allows the light to wash through the wall like water. It is mainly used for architectural decoration lighting and also used to outline the outline of large buildings. Because LED has the characteristics of energy saving, high luminous efficiency, rich color, long life and so on. So, do you know the key technical requirements for the design of an LED wall washer?
1. Drive power：
The driving power supply is an LED lighting product with high efficiency, low heat generation and good stability. The non-isolated driving power supply characteristics generally need to be constant current and wide voltage, that is, the city voltage is 85-265V, which is very common. Yes, low power consumption, high efficiency, and in some cases, high power factor, open circuit and short circuit protection, output overvoltage protection, high load capacity, etc. are required, and it also involves the driving power supply. Some safety designs should be adopted, and physical insulation methods are adopted to achieve absolute safety even when using non-isolated driving power supplies.
2. LED light source:
The light source of the LED wall washer must also be very particular. In order to achieve a certain brightness, it is necessary to pay attention to the selection of the light source. Different lamp beads use different designs, and the heat dissipation effect is also different, and the light effect is also different.
At present, the common LED wall washer heat dissipation structure on the market is made of aluminum, and then the heat is directed to the external aluminum through the aluminum substrate of the lamp bead for heat dissipation, so the purity of this material determines the quality of that Whether the heat dissipation reaches the target, if the heat dissipation material is not handled well, it will greatly affect the life of that, and it will also affect the quality of the LED wall washer lighting effect.
