Abstract:
The present invention is a control method of color temperature and luminance for an LED device and a control system thereof. The control method has the following steps: executing a cold-start motion; determining whether a warm-start motion is executed during a preset time; if yes, adjusting the color temperature of the LED device, and determining whether the warm-start motion is executed again during the preset time; if not, adjusting the luminance of the LED device, and determining whether the warm-start motion is executed again. A user can adjust the color temperature and the luminance of the LED device by turning off and on a switch of the control system.
Abstract:
A lighting device has a light-bar mount and multiple light bars. The light-bar mount is integrally formed from a board. The light bars are mounted on the light-bar mount and each light bar has a heat sink, a circuit board and multiple high-power LED modules. The heat sink is detachably mounted in the light-bar mount. The circuit board is mounted in the heat sink. The high-power LED modules are mounted on the heat sink and electrically connected to the circuit board for providing outward illumination.
