    • Broad spectrum light emitting devices and methods and semiconductor chips for fabricating such devices include a light emitting element, such as a diode or laser, which emits light in a predefined range of frequencies. The light emitting element includes a shaped substrate suitable for light extraction through the substrate and a cavity in the substrate proximate the light emitting element. For example, a trench adjacent at least a portion of the periphery of the light emitting element may be provided. The cavity/trench is configured to contain light conversion material such that light extracted from sidewalls of the cavity/trench passes through the light conversion material contained in the cavity/trench. Methods of fabricating such devices and/or chips are also provided.
    • 用于制造这种器件的广谱发光器件和方法以及半导体芯片包括发射预定频率范围内的光的诸如二极管或激光器的发光元件。 发光元件包括适合于通过基板的光提取的成形基板和靠近发光元件的基板中的空腔。 例如,可以提供与发光元件的周边的至少一部分相邻的沟槽。 空腔/沟槽被配置为容纳光转换材料,使得从空腔/沟槽的侧壁提取的光通过包含在空腔/沟槽中的光转换材料。 还提供了制造这种装置和/或芯片的方法。

    • In one form of the present preferred embodiment of the present invention it relates to a three-position feed-thru electric line or wire cord piercing switching combination of the rotary type which at least saves electric energy by use of a half-wave diode rectifying means. The electric energy saving, three-position, combination switch having one "off" and two electrical passing switching positions. The switch will provide three-positions of 120 degrees for each position so that machine-gun or gunning, overshooting or rapid manual switch actuation for each of the three-positions is substantially prevented and also provides an electrical "off" half-wave rectified "dim" and an electrical full-wave "on" illumination to a single filament lamp, string of Christmas tree lamps and the like, and will even provide at least eight separate combination, of three illuminations, when electrically connected ahead of a, for example, conventional LEVITON rotary 3-way lamp socket switching means which uses a conventional 3-way incandescent lamp member which is removable inserted into the lamp socket portion thereof. The half-wave diode rectifying means is electrically connected to and substantially shuntingly between two of three electrical contact members of the conductor wire-piercing and the wire non-piercing type of switch.
