Electronic ballast of metal halide lamp for projector with digital control
A novel digital control theory is proposed for the metal halide lamp electronic ballast used for the projector. The resonant ignition with LCSCP mode is adopted here, an adaptive digital control method for ignition is proposed to overcome the problem of the deviation for the passive components. A simple power closed loop method is proposed to make the lamp power constant without the power over ...
متن کاملMetal halide perovskite light emitters.
Twenty years after layer-type metal halide perovskites were successfully developed, 3D metal halide perovskites (shortly, perovskites) were recently rediscovered and are attracting multidisciplinary interest from physicists, chemists, and material engineers. Perovskites have a crystal structure composed of five atoms per unit cell (ABX3) with cation A positioned at a corner, metal cation B at t...
متن کاملMetal Transfer and Arc Plasma in Gas Metal Arc Welding
This article analyzes the transient complex heat transfer and fluid flow in molten metal and arc plasma during the gas metal arc welding process. The model predicts the formation, growth, detachment, and transfer of droplets from the tip of a continuously fed electrode under the influences of several competing forces including gravity, electromagnetic force, arc pressure, plasma shear stress, a...
متن کاملOptical pumping of helium with arc lamp excited LNA lasers
2014 We have developed a compact and relatively inexpensive laser source at 03BB =1.083 03BCm, suitable for optical pumping in helium. The laser is made of an LNA crystal transversely pumped by krypton arc lamps. A cw power of 800 mW has been achieved at 1.083 03BCm with a 3 GHz bandwidth. A 66 % nuclear polarization has been obtained in a 3He gas. Revue Phys. Appl. 24 (1989) 827-831 AOÛT 1989,
متن کاملLead Halide Perovskites and Other Metal Halide Complexes As Inorganic Capping Ligands for Colloidal Nanocrystals
Lead halide perovskites (CH3NH3PbX3, where X = I, Br) and other metal halide complexes (MX(n), where M = Pb, Cd, In, Zn, Fe, Bi, Sb) have been studied as inorganic capping ligands for colloidal nanocrystals. We present the methodology for the surface functionalization via ligand-exchange reactions and the effect on the optical properties of IV-VI, II-VI, and III-V semiconductor nanocrystals. In...
