Illumination system having color temperature control and method for controlling the same
First Claim
1. An illumination system, comprising:
- a power supply unit; and
a light emitting apparatus driven by power supplied from the power supply unit,wherein the light emitting apparatus comprises;
a first light emitting portion and a second light emitting portion disposed in a same light emitting package and configured to be independently driven to emit output light; and
a controller configured to control at least one of a color temperature and a luminous flux of the output light by controlling operations of the first and second light emitting portions, andwherein the controller is configured to generate a first control signal based on luminous flux control data and a second control signal based on color temperature control data,and the controller is configured to output the first control signal to control an output luminous flux of the first light emitting portion and output the second control signal to control a color temperature of the second light emitting portion.

Abstract
An illumination system includes a power supply unit; and a light emitting apparatus driven by power supplied from the power supply unit. The light emitting apparatus includes: a first light emitting portion and a second light emitting portion configured to be independently driven to emit output light; and a controller configured to control a color temperature or a luminous flux of the output light by controlling operations of the first and second light emitting portions. The controller is configured to control an output color temperature of the output light according to color temperature control data for controlling an output color temperature of the second light emitting portion or control a luminous flux of the output light according to luminous flux control data for controlling an output luminous flux of the first light emitting portion.

12. A method for controlling illumination system, the method comprising:
-
storing environment-related control data in an information storage unit; detecting ambient information outside the illumination system; determining at least one of a luminous flux and a color temperature for the illumination system based on the environment-related control data and the ambient information; controlling a first light emitting portion and a second light emitting portion based on the at least one of the luminous flux and the color temperature; generating a first control signal based on luminous flux control data; generating a second control signal based on color temperature control data; outputting the first control signal to control an output luminous flux of the first light emitting portion; and outputting the second control signal to control a color temperature of the second light emitting portion, and wherein the first light emitting portion and the second light emitting portion are disposed in a same light emitting package and independently driven to emit output light. - View Dependent Claims (13)
