Abstract
A light emitting diode (LED) module is disclosed. The LED module includes a plurality of LED strings each including a plurality of LEDs in a serial connection with each other and disposed with respect to a central axis of a base board in a co-axial fashion, a plurality of drivers each connected to the corresponding LED string for providing adjustable driving currents to trigger each of the LED strings respectively and to adjust a color temperature of each of the LED strings, and a controller, connected to the plurality of drivers, for generating a plurality of output signals and outputting the output signals to the plurality of drivers respectively in response to a predetermined setting so as to adjust the color temperature.
Claims17
A light emitting diode (LED) module, comprising:
- a plurality of LED strings each including a plurality of LEDs in a serial connection with each other wherein the LED strings are disposed with respect to a central axis of a base board in a co-axial fashion;
- a plurality of drivers each connected to the corresponding LED string, for providing adjustable driving currents to trigger each of the LED strings respectively and to adjust a color temperature of each of the LED strings;
- and
- a controller, connected to the plurality of drivers, for generating a plurality of output signals and outputting the output signals to the plurality of drivers respectively in response to a predetermined setting so as to adjust the color temperature.
A (light emitting diode) LED lamp apparatus, comprising:
- a base board;
- and
- a LED module having a plurality of LED strings each including a plurality of LEDs connected in series, a plurality of drivers each connected to the corresponding LED string, and a controller connected to the drivers, wherein the LED strings are disposed co-axially with respect to a central axis of the base board;
- wherein the driving current outputted by the drivers and transmitted to the LED string according to a predetermined setting corresponds to an adjustable color temperature.
A method for adjusting a color temperature of a (light emitting diode) LED module in a LED lamp apparatus, comprising the steps of:
- receiving a signal indicative of a predetermined setting by a controller;
- generating a plurality of output signals to a plurality of drivers respectively in response to the predetermined setting by the controller;
- and
- outputting a plurality of driving currents to a plurality of LED strings in the LED module for adjusting the color temperature thereof wherein the LED strings are disposed with respect to a predetermined axis in a co-axially fashion with respect to a base board of the LED module.
