Module street lamp is a widely used product in LED products. It also has a very big difference in structure and optoelectronics. It is simple to use a pcb circuit board equipped with LED and a chassis to become an LED module. With some manipulation, the DC power supply and the corresponding exhaust heat treatment make the LED life and brightness unit stronger.

LED control module, this is used on the LED module street lamp, in fact it refers to the light source of small LED blocks, which can be made up of different total number of control modules to form LED lights of different sizes and efficiencies, such LED lights , Now everyone aliases modular design lighting fixtures. According to the different processing technology of LED module street lamp surface treatment, we can divide it into software modules, surface mount modules, sub-surface mount modules, three-in-one surface mount modules, and three-in-one surface mount modules.

The software module refers to the module street lamp in the form of DIP package that passes the lamp foot over the PCB board, and fills the lamp hole with tin according to electric welding. The advantage is that the angle is large, brighter, and heat dissipation is good; the disadvantage is that the screen pixel density is small.

Surface mount module, also known as SMT, the module street lamp in the form of SMT package is welded on the surface of the PCB board according to the welding method, and the lamp feet do not need to go over the PCB board. The density is high, suitable for viewing in the room; the defect is that the chromaticity is not high enough, and the LED lamp itself is not good enough for heat dissipation.

The sub-surface mount module is a commodity between DIP and SMT. The package form of the module street lamp is the same as the surface layer of SMT, but its positive and negative pins are the same as those of DIP, and they also cross the PCB during production. For electric welding, the LED module street lamp made by this type of processing technology has the advantage of being brighter, indicating that the effect is very good. The disadvantage is that the processing technology is complicated and the maintenance is difficult.

The three-in-one surface mount means that the LED chips with different colors of R, G, and B are packaged in the same colloidal solution; the advantage of the module street lamp is that it is easy to manufacture, which shows that the effect is very good, but the disadvantage is the light splitting adjustment. The color is difficult and the cost increases.
