  2. Hardware interface design - Wikipedia

    en.wikipedia.org/wiki/Hardware_Interface_Design

    Hardware interface design (HID) is a cross-disciplinary design field that shapes the physical connection between people and technology in order to create new hardware interfaces that transform purely digital processes into analog methods of interaction. It employs a combination of filmmaking tools, software prototyping, and electronics ...

  3. High-intensity discharge lamp - Wikipedia

    en.wikipedia.org/wiki/High-intensity_discharge_lamp

    HID lamps are used in high-performance bicycle headlamps, as well as flashlights and other portable lights, because they produce a great amount of light per unit of power. As the HID lights use less than half the power of an equivalent tungsten-halogen light, a significantly smaller and lighter-weight power supply can be used.

  5. Gas-discharge lamp - Wikipedia

    en.wikipedia.org/wiki/Gas-discharge_lamp

    A high-intensity discharge (HID) lamp is a type of electrical lamp which produces light by means of an electric arc between tungsten electrodes housed inside a translucent or transparent fused quartz or fused alumina arc tube. Compared to other lamp types, relatively high arc power exists for the arc length.

  6. Metal-halide lamp - Wikipedia

    en.wikipedia.org/wiki/Metal-halide_lamp

    It is a type of high-intensity discharge (HID) gas discharge lamp. [1] Developed in the 1960s, they are similar to mercury vapor lamps, [1] but contain additional metal halide compounds in the quartz arc tube, which improve the efficiency and color rendition of the light. The most common metal halide compound used is sodium iodide. Once the arc ...
