Features:
Angle 120- 180 degrees, uniform color and high brightness.
The net constant current circuit design has super anti-static function to ensure the stability of the module.
Anti-static PVC profile base is adopted to effectively prevent PCB solder joints from contacting with metal shell to cause short circuit.
Using I-type, Y-type and X-type connecting wires, the module installation is convenient and fast; With self-locking connector, more connections are made.
Freedom.
Low power consumption and pure color; Long life and high stability. Convenient connection, each module contains plug and socket wires, which is convenient for connection. Light weight, compact structure and convenient installation. There are various sizes and specifications, suitable for fonts of any size. Low voltage power supply, safe and reliable.
Widely used in toys
At present, it is not suitable for making lamps (lighting needs more power, and straw hat series is obviously not competent)
Gray scale representation is not needed, and power consumption is generally low. Even if 74HC595 is used without constant current, it will not cause LED damage.
disadvantaged
The heat dissipation of straw hat lamp itself is not particularly good, because it is dissipated through two pins, and poor heat dissipation will bring other effects (light decay, life). Secondly, the volume of straw hat lamp also
It is relatively large and does not meet the current requirements. The straw hat lamp series decayed to 90% for thousands of hours. If we use lighting for 6 hours every day, then 1 year needs 2 190 hours. The LED is substantially attenuated to
70% brightness is considered as the end of life, so we can't see that 1 year loses its use value.
