Customers first outline the LED light bar, and then find the switching power supply. They find it difficult to have a suitable switching power supply. Either the power flow is very large and the working voltage is very small (such as I > 350mA, V < 40V); otherwise the current is very small and the working voltage is too high (such as I < 40mA, V > 180V). The result is that the heat is not optimistic, the output power is low, and perhaps the operating scale is insufficient. In fact, the wall washing lamp manufacturers choose an excellent series parallel connection mode, and the current and voltage applied to each LED are the same, while the role of the power supply can carry forward the role of the bar. The best way is to communicate with the switching power supply manufacturer first and tailor it.
The purchase of LED wall washing lamp is particularly important for all LED lighting. It is related to the final expression of all LED lighting projects, and it is whether all projects can stand the test of time. But there are many people who don't understand. In the case of purchase, they only ask for the detailed introduction of the general manager. In fact, what they have made clear is only a little bit. It's very easy to fall into the wrong idea. Now let me tell you what are the three mistakes in purchasing LED lights.
The lighting perspective of LED is divided into reasonable perspective and specific lighting perspective. The intersection angle between half of the axial diameter compressive strength value of brightness unit value and the luminous axial diameter (opposite direction) is a reasonable angle of view. Two times of half value angle (or half output power angle) is the specific lighting angle. Because of the weak light source, the angle beyond half of the axial compressive strength is not reasonable in the specific application.
Every big city attaches great importance to the lighting work of big cities, and has carried out the lighting construction of big cities at different levels. The construction of the lighting project of big cities is regarded as the key countermeasure to improve and clean up the natural environment of big cities. It has become the consensus of leading cadres and people from all walks of life to make big cities bright and beautiful. The outdoor lighting projects are mainly the construction of wall lighting, urban square, residential district lighting and other projects; the purpose of lighting design is to use the lighting effect to reconstruct the landscape at night, and present the beautiful and neat landscape at night. Therefore, lighting design should also consider the harm to landscape plants, so that the ecosystem is more and more harmonious.
