The safe use current of stainless steel light boxes is generally 20 mA. If this value is exceeded, although the brightness will increase, the color attenuation will be significantly accelerated. Therefore, when purchasing an assembled stainless steel module, be sure to test its output current value. Less than 20 mA is not enough brightness, more than 22 mA affects the life of stainless steel and accelerates color decay.
Most of the light-emitting modules on the market are connected by patch cords. In this way, it is convenient and quick for the advertisement maker to install the light-emitting module. However, some new problems have also appeared. Because the connectors are easily oxidized by the moisture in the air during the long-term use, the contact is poor, and the partial or all circuits are powered off instantaneously or completely, resulting in flickering of the font light source or not bright. The solutions are: 1. Do not use connectors when making modules, directly connect them with copper tinned wires and then use activated carbon solder to weld them firmly. Artificial agate is used to make fully enclosed hollow three-dimensional luminous characters to isolate the contact between the light source and the air.
Try to use a stainless steel light-emitting module with a set of five light boxes, so that the number of light boxes does not change, but the power is reduced by one-fifth. The safe use current of stainless steel light boxes is generally 20 mA. But the falloff of the color will be significantly faster. Therefore, when purchasing an assembled stainless steel module, be sure to test its output current value. Less than 20 mA is not enough brightness, more than 22 mA affects the life of stainless steel and accelerates color decay.
