Abstract

A light-emitting apparatus includes a first light emitter configured to emit visible light and including a plurality of light sources having color temperatures different from each other, a second light emitter configured to emit infrared rays, and a controller configured to adjust characteristics of the visible light and the infrared rays by controlling the first and second light emitters, in which each of the light sources includes a light-emitting diode chip and a wavelength conversion unit configured to convert a wavelength rage of light emitted from the light-emitting diode chip.

Claims (14)

1. A lighting device comprising:

a first light emitter comprising a plurality of light sources each being configured to emit light with a different color temperature;

a second light emitter comprising at least one light emitting structure configured to emit light having a longer peak wavelength than that emitted from the first light emitter;

a controller configured to adjust characteristics of light emitted from the first and second light emitters; and

a user interface member configured to receive input of a user and connected to the controller,

wherein each of the light sources comprises a light-emitting diode chip and a wavelength conversion member configured to convert a wavelength range of light emitted from the light-emitting diode chip, and

wherein the controller is further configured to disable the second light emitter in response to receiving an input for prohibiting emission of the light emitting structure through the user interface member.

2. The lighting device according to claim 1 , wherein the user interface member further comprises a module configured to display various types of information related to light emitted from the lighting device.

3. The lighting device according to claim 2 , wherein the user interface member is configured to display intensity, a color temperature, or a spectrum of light currently emitted from the lighting device.

4. The lighting device according to claim 1 , further comprising a storage medium,

wherein the controller is further configured to store data for driving condition applicable to the first light emitter and the second light emitter.

5. The lighting device according to claim 4 , wherein the controller is further configured to control the first and second light emitters according to a spectrum of light stored in the storage medium.

6. The lighting device according to claim 1 , further comprising an optical sensor configured to sense external light.

7. The lighting device according to claim 6 , wherein the controller is further configured to acquire a spectrum of the external light by communication with the optical sensor and compare the spectrum of the external light with a spectrum of light emitted from the first and second light emitters to control the first and the second light emitters according to a result of the comparison.
