<p>The present invention relates to an LED lighting device, more particularly to an LED lighting device which can control LED brightness of two colors or more by counting the number of control signals (the number of pulses) outputted from a microcontroller. The disclosed LED lighting device can prevent heat generation and reduce power loss, which are caused by overcurrent of a drive circuit. In addition, since the brightness of each RGB LED can be stably controlled, various light effects can be exhibited.</p> |
