Within the heating assembly are the circular halogen lamp, a fan, [3] and the controls for the oven which frequently include an automatic shut-off timer and a temperature control interface. [2] [4] On a basic model, the heating assembly has a handle to allow users to safely lift the lid off the unit. More elaborate models have a hinged lid ...
A halogen lamp operating in its fitting with the protecting glass removed A halogen lamp behind a round UV filter. A separate filter is included with some halogen light fixtures to remove UV light. Halogen lamp (105 W) for replacement purposes with an E27 screw base A close-up of a halogen lamp capsule
A ceramic hob with two multi-zone radiant heaters. A ceramic radiation heating cooktop has a surface made of low-expansion thermal glass-ceramic that is transparent to infrared. [5] This surface houses radiant or halogen heaters below it. The advantage of this arrangement is that the heat can be quickly controlled.
Left to right: MR16 with GU10 base, MR16 with GU5.3 base, MR11 with GU4 or GZ4 base Line drawing of an LED MR16 lamp, with a heatsink rather than a reflector. A multifaceted reflector (often abbreviated MR) light bulb is a reflector housing format for halogen as well as some LED and fluorescent lamps.
Like other gas-discharge lamps such as the very-similar mercury-vapor lamps, metal-halide lamps produce light by ionizing a mixture of gases in an electric arc.In a metal-halide lamp, the compact arc tube contains a mixture of argon or xenon, mercury, and a variety of metal halides, such as sodium iodide and scandium iodide.

Xenon, or high-intensity discharge (HID), lighting provides brighter headlights and increases visibility of many peripheral objects (e.g. street signs and pedestrians) left in the shadows by standard halogen lighting. However, the bright headlights have given rise to complaints about glare. [10]
In a kitchen the hob is a projection, shelf, grate or bench for holding food or utensils at the back or side of a hearth to keep them warm, or an internal chimney-corner. In modern British English usage, the word refers to a cooktop or hotplate , as distinguished from an oven .
The spectrum of light emitted from a fluorescent lamp is the combination of light directly emitted by the mercury vapor, and light emitted by the phosphorescent coating. The spectral lines from the mercury emission and the phosphorescence effect give a combined spectral distribution of light that is different from those produced by incandescent ...
