What Are the Two Parts of the LED Light Source Module

The LED light source module is divided into two parts, one is a variety of LED screens specifically for outdoor, mainly used for display and backlight; the other is specifically used for LED lighting classes. Here we mainly talk about LED light source modules. The light source modules used for LED lighting are divided into two parts: DC module and AC module. DC module is Direct Current English abbreviation, AC module is to exchange Alternating Current English abbreviation. Different modules are different from the lamps. The DC modules are divided into constant current modules and constant voltage modules. They need to be applied to the lamps together with the driver. The AC module is different. Municipal Electric Application on Lantern. The constant stream module, that is, the module board current is constant, the voltage can be adjusted appropriately. The constant voltage module is the fixed voltage of the module board, and the current can be adjusted at will. At present, 12V, 24V, and 48V are more common. The AC module already has its own power supply system, which can be connected directly to the municipal electricity. Different modules are applied to different lamps. The constant stream module is mostly used on fixed and separately used lamps; constant pressure modules are mostly used for combinations, infinite stitching lamps; AC modules can use various lamps, focusing on Cost consideration. The AC module is directly connected to the market. Many users are worried about safety and do not dare to use it. In fact, as long as the structure is processed, it is very safe to use the lens or colloid to protect the high voltage part and not let people contact With the improvement of technology, this aspect can be well avoided; and because the DC module has been driven, it is low -voltage electricity, so the safety performance is relatively strong. However, after the driver is added, the cost will increase the cost. , The lamp body will change.
