Method for manual and automatic dimming and device thereof
Disclosed is a method for manual and automatic dimming and a device thereof, the method comprising: installing optical sensors and control units on a plurality of LED lights; through switching on a single power switch, allowing the control units to respectively adjust, in an automatic manner, the lighting brightness of the LED lights according to the surrounding brightness detected by the optical sensors; performing via manual operation short-term turning off the power switch; and then using the control unit to synchronously adjust the lighting brightness or color temperature of the LED lights. As such, the convenience of installation and use is improved.
Abstract We present a magneto-optical study of p -type Zn 1− x Mn x O diluted magnetic semiconductors (DMS) obtained by thermal oxidation Zn 1− x Mn x Te layers. Photoluminescence spectra were used to determine the “giant” Zeeman splitting and to estimate the exchange integrals N 0 (α−β)∼0.1 eV. This is an extremely small value for a II–VI DMS, and we discuss possible reasons for this effect.
