摘要:
The present invention generally relates to an extraction structure for a UV lighting element. The present invention also relates to a UV lamp comprising such an extraction structure onto a substrate. The extraction structure comprises a plurality of nanostructures for anti-reflecting purposes. The nanostructures are grown on the top surface of at least one of the first and second side of the substrate.

This control, device, for a representative lamp (L1), by way of a power control circuit (20), detects the cathode (1k) from a resistor (TRk1), and controls a high-voltage stabilizing circuit (10), and performs drive controls so that the gate voltages, which were divided from the output voltage (Vgo) from the high-voltage stabilizing circuit (10), become suitable voltages. Moreover, the control device, for other lamps (L2..., Ln), by way of the power control circuit (20), changes the voltage dividing ratio of impedance dividing by resistors (R2_1, R2_2, ..., Rn_1,Rn_2) for the Output voltage (Vgo) using control elements (Q2, ...., Qn), and performs control so that the cathode current of each of the lamps (L2,..., Ln) becomes the same as the cathode current of the representative lamp (L1)
摘要:
A target for ultraviolet light generation comprises a substrate adapted to transmit ultraviolet light therethrough and a light-emitting layer disposed on the substrate and generating ultraviolet light UV in response to an electron beam. The light-emitting layer includes a powdery or granular rare-earth-containing aluminum garnet crystal doped with an activator. The light-emitting layer has an ultraviolet light emission peak wavelength of 300 nm or shorter.
