heating may be accomplished by passing the assembly through a reflow oven or under an infrared lamp or by soldering individual joints unconventionally with a desoldering hot air pencil. reflow soldering with long industrial convection ovens is the preferred method of soldering surface mount components to a printed circuit board or pcb. each segment of the oven has a regulated temperature, according to the specific thermal requirements of each assembly.
some applications use the heat generated by the filament, such as incubators, brooding boxes for poultry, heat lights for reptile tanks, infrared heating for industrial heating and drying processes, lava lamps, and the easy-bake oven toy. quartz tube heat lamps are used for industrial processes such as paint curing or for space heating .
infrared pyrometer. the most common infrared thermometer is the spot infrared pyrometer or infrared pyrometer, which measures the temperature at a spot on a surface actually a relatively small area determined by the d:s ratio . these usually project a visible red dot onto the center of the area being measured that identifies the spot being .
thermal radiation, also known as heat, is the emission of electromagnetic waves from all matter that has a temperature greater than absolute zero. it represents the conversion of thermal energy into electromagnetic energy. thermal energy consists of the kinetic energy of random movements of atoms and molecules in matter. all matter with a .
an infrared heater or heat lamp is a body with a higher temperature which transfers energy to a body with a lower temperature through electromagnetic radiation. depending on the temperature of the emitting body, the wavelength of the peak of the infrared radiation ranges from 780 nm to 1 mm. no contact or medium between the two bodies is needed for the energy transfer.
ultraviolet germicidal irradiation uvgi is a disinfection method that uses short-wavelength ultraviolet ultraviolet c or uvc light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their dna, leaving them unable to perform vital cellular functions. uvgi is used in a variety of applications, such as food, air, and water purification.
a solar cooker is a device which uses the energy of direct sunlight to heat, cook or pasteurize drink and other food materials. many solar cookers currently in use are relatively inexpensive, low-tech devices, although some are as powerful or as expensive as traditional stoves, and advanced, large-scale solar cookers can cook for hundreds of .
heat therapy, also called thermotherapy, is the use of heat in therapy, such as for pain relief and health. it can take the form of a hot cloth, hot water bottle, ultrasound, heating pad, hydrocollator packs, whirlpool baths, cordless fir heat therapy wraps, and others. it can be beneficial to those with arthritis and stiff muscles and injuries to the deep tissue of the skin.
reflow soldering is a process in which a solder paste a mixture of prealloyed solder powder and a flux-vehicle that has a peanut butter-like consistency is used to stick the components to their attachment pads, after which the assembly is heated by an infrared lamp, a hot air pencil, or, more commonly, by passing it through a carefully .
an incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a wire filament heated until it glows. the filament is enclosed in a bulb to protect the filament from oxidation.current is supplied to the filament by terminals or wires embedded in the glass.
infrared lamps deliberately use the heat generated by the filament, for uses such as incubators, brooding boxes for poultry, heat lights for reptile tanks, infrared heating for industrial heating and drying processes, lava lamps, and the easy-bake oven toy. incandescent bulbs typically have short lifetimes compared with other types of lighting; around 1,000 hours for home light bulbs versus typically 10,000 hours for compact fluorescents and 30,000 hours for lighting leds.

a halogen oven, halogen convection oven, or halogen cooking pot is a type of oven that utilizes a halogen lamp as its heating element. it is used primarily for cooking. halogen ovens are often noted for being more energy-efficient than a conventional oven due to their use of a halogen lamp reducing the cooking time usually needed in a conventional oven. halogen cooking pot from manufacturer german pool
electric heating is widely used in industry. advantages of electric heating methods over other forms include precision control of temperature and distribution of heat energy, combustion not used to develop heat, and the ability to attain temperatures not readily achievable with chemical combustion. electric heat can be accurately applied at the .
these devices are widely used in manufacturing involving conveyors or 'web' processes, such as large sheets of glass or metal exiting an oven, fabric and paper, or continuous piles of material along a conveyor belt. infrared thermal imaging cameras or infrared cameras are essentially infrared radiation thermometers that measure the temperature .
a microwave oven is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. this induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating. microwave ovens heat foods quickly and efficiently because excitation is fairly uniform in the outer 25–38 mm of a homogeneous, high water content food item. the development of the cavity magnetron made possible the production of .
an electric light is a device that produces visible light from electric current.it is the most common form of artificial lighting and is essential to modern society, providing interior lighting for buildings and exterior light for evening and nighttime activities. in technical usage, a replaceable component that produces light from electricity is called a lamp.
a headlamp is a lamp attached to the front of a vehicle to illuminate the road ahead. headlamps are also often called headlights, but in the most precise usage, headlamp is the term for the device itself and headlight is the term for the beam of light produced and distributed by the device.
a shrink tunnel or heat tunnel is a heated tunnel mounted over or around a conveyor system.items such as packaging have shrink film loosely applied; with heat, the film shrinks to fit snugly around the wrapped object.
infrared signature, as used by defense scientists and the military, is the appearance of objects to infrared sensors.an infrared signature depends on many factors, including the shape and size of the object, temperature, and emissivity, reflection of external sources earthshine, sunshine, skyshine from the object's surface, the background against which it is viewed and the waveband of the .
carbide lamps, or acetylene gas lamps, are simple lamps that produce and burn acetylene c 2 h 2 which is created by the reaction of calcium carbide cac 2 with water h 2 o .. acetylene gas lamps were used to illuminate buildings, as lighthouse beacons, and as headlights on motor-cars and bicycles. portable acetylene gas lamps, worn on the hat or carried by hand, were widely used in mining .
ir welding is a welding technique that uses a non-contact heating method to melt and fuse thermoplastic parts together using the energy from infrared radiation. the process was first developed in the late 1900s, but due to the high capital cost of ir equipment the process was not commonly applied in industry until prices dropped in the 1990s.
