1. Driving power supply
I believe many friends who have used LED products know that driving power supply can be said to be the most important part of LED lighting products. A high efficiency, low heating, good stability of the driving power supply for LED lighting products is particularly important, LED wall lamp is no exception, now we take the non-isolated driving power supply to discuss with you.
The characteristics of non-isolated driving power supply should be constant current and wide voltage, i.e. the city voltage is 85-265V, which is very common. It also needs low power consumption, high efficiency, high power factor in some cases, and has the requirements of open circuit short circuit protection, output overvoltage protection, high load capacity and so on. At the same time, it also needs to adopt some safety in the part of driving power supply. Design, using physical insulation, even in the use of non-isolated driving power supply can achieve absolute security.
2. LED Light Source
In order to achieve a certain brightness, we need to pay attention to the choice of light source is different in the design of different beads, and the effect of heat dissipation is also different, of course, the light effect is also different, can not choose some low-grade, low-brightness beads in order to save costs to charge, whether the brightness of an LED wall lamp is up to the standard depends entirely on the light source, the light source is not well done can also be said. What brightness? So the light source of LED wall lamp is also very exquisite.
At present, the common heat dissipation structure of LED wall lamp in the market is aluminium material, and then heat is directed to the external aluminium material through the aluminium base plate of the lamp beads for heat dissipation, so the purity of this material determines whether the heat dissipation of an LED wall lamp meets the standard. If the heat dissipation material is not handled properly, it will greatly affect the life of the LED wall lamp, and also affect its own LED washing. Wall lighting quality. Choosing a good radiator is also an aspect we should pay attention to.
However, since 2013, LED wall-wash lamps have been widely used in various places, involving a wider and wider range, from indoor to outdoor, from partial lighting to overall lighting, are the level of improvement and development; nowadays, LED wall-wash lamps have been invested in the lighting project, in the next few years, LED wall-wash lamps will become an indispensable part of the lighting project. The development direction of LED wall lamp is compact and light in volume and high power LED light source in power. Therefore, it is necessary to master the small skills of a product.
