    • PROBLEM TO BE SOLVED: To provide a cost-effective solution for maintaining precise control over the relative brightness of different LED channels while still allowing for current variations between LED channels.SOLUTION: The present invention relates to a system that provides an intelligent approach to driving multiple strings of LEDs. A processing device determines an optimal current level for each LED string from a limited set of allowed currents. The processing device also determines a PWM duty cycle for driving the LEDs in each LED string to provide precise brightness control over the LED string. The settings for the current level and duty cycle are transmitted to an LED driver for regulating the current and on-off times of the LED strings. Beneficially, the system reduces the size of the LED driver while leveraging existing resources available in the processing device to operate the LEDs in a power-efficient manner.
    • 要解决的问题:为了保持对不同LED通道的相对亮度的精确控制,同时仍然允许LED通道之间的电流变化,提供了一种经济有效的解决方案。 解决方案:本发明涉及一种提供智能方法来驱动多串LED的系统。 处理装置从有限的允许电流集合确定每个LED串的最佳电流电平。 处理装置还确定用于驱动每个LED串中的LED的PWM占空比,以提供对LED串的精确亮度控制。 当前电平和占空比的设置被传送到LED驱动器,用于调节LED串的电流和开关时间。 有利的是,该系统减少了LED驱动器的尺寸,同时利用处理装置中可用的现有资源以功率有效的方式操作LED。 版权所有(C)2013,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide an LED lamp in which the output light intensity of an LED in the LED lamp is adjusted on the basis of an input voltage to the LED lamp.SOLUTION: An LED lamp 80 includes: one or more LEDs 90; and an LED driver 92 receiving an input voltage 84 and providing regulated current to the one or more LEDs 90. The LED driver 92 adjusts the regulated current to the one or more LEDs 90 according to the input voltage 84 to adjust the output light intensity of the one or more LEDs 90. The LED lamp 80 can be directly replaced with conventional incandescent lamps 20 in typical wiring configurations found in residential and commercial building lighting applications that use conventional dimmer switches 10. The conventional dimmer switches 10 carry out dimming by changing the input voltage 84 to the LED lamp 80.
