LIGHT EMISSION APPARATUS, ILLUMINATION SYSTEM AND ILLUMINATION METHOD |
摘要 |
A light emission apparatus includes: a wiring board; a plurality of LED chips that are disposed on an LED chip mounting surface of the wiring board and are grouped into a plurality of LED groups; a wavelength conversion member that is disposed at a position corresponding to the LED chip mounting surface of the wiring board, converts a wavelength of light emitted by the corresponding LED chips, and emits first-order light with a different color temperature for each wavelength conversion region; a current supply section that supplies a driving current to the LED chips independently for each LED group through the wiring board; and a control section that controls the current amount supplied for each LED group in response to a control signal. The control section independently controls timing of starting to light the LED groups in accordance with the light control level. |
