These halogen lamp heaters were developed to efficiently extract the infrared light from the halogen lamp, with more than
85% of the input power converted into heat, resulting in a very efficient energy source.
Heating by halogen lamp is rich in flexibility and controllability, with excellent characteristics no other heat source can provide. Ushio's heat processing systems are used in various industrial fields such as electronic device manufacturing processes like semiconductors and LCDs, and heating of auto parts and resin materials such as CFRP.

Highly efficient energy sources
Over 85% of the input power is converted to infrared radiation for a highly efficient lamp-type radiant heat source.
Reduced power consumption means lower running costs.
Excellent heating and cooling performance
Non-contact rapid heating and cooling is achieved by a low-heat-capacity tungsten filament.
For example, it is possible to heat aluminum to 300℃ in only 10 seconds.
By reducing heating times, processing capabilities have been improved.
In addition, unlike resistive heating that continually consumes power, the ability to be ON or OFF as needed lowers running costs.
Wavelength of light matches the material absorption characteristics
Matching the absorption characteristics of various metals and the wavelength output of halogen lamp heaters, enables high efficiency, as well as, heating processes that are not possible with high-frequency heating and hot air.
Highly controllable
Superior thermal control has been achieved through the optically designed heater unit and dedicated PID control system that other heat sources cannot match.
A non-contact in-plane temperature ±5% distribution has been achieved.
Compact, clean heat source
Halogen lamp heaters can be installed in narrow spaces since they can output a large amount of energy in spite of their small size and light weight. In addition, maintaining a clean atmosphere or whether heating in air or a vacuum are not issues for non-contact heating. Photoheating also emits no gases, so it can contribute to CO2 emission reduction.
Constant-energy emission over long lifespan
Using the halogen cycle enables a design with a long lifespan unmatched by other halogen lamp heaters. Furthermore, as there are no changes over time as with other heat sources, near constant-energy emission is maintained over the entire lifespan and results in improved maintainability.
This alternative heat source replaces conventional electric/gas furnace, electric and induction heating for hot forming processing of advanced thermoplastic materials such as used for car chassis, hot press of steel plates constituting axles, engineering plastics and CFRP. In recent years, we have also been participating in advancing applications for electric and hybrid car secondary battery manufacturing processes, and fuel cell stack and resin fuel tank manufacturing processes for fuel cell vehicles.
From low to high temperatures and from atmospheric pressure to high vacuum, this is used as an industry-standard heat source for semiconductor manufacturing processes such as oxide-layer formation, activation after ion implantation and silicide formation. It also serves an important role as an assist heater or auxiliary heat source.
Flat panel displays
Non-contact heating and fast heating and cooling are provided, with length increased up to 2.5 m to support longer substrate sizes. It is also effective in high vacuum baking chambers.
Solar cells
Non-contact heating and fast heating and cooling by halogen heater lamp are used for mounting heat treatment devices such as firing furnaces, CVD and dryers.
As a heat source for thermoplastic resin molding, many halogen lamp heaters are used for roll-to-roll continuous film heating.
Home appliances and more
The non-contact heating of the halogen heater is effective for heating molds used to form compact camera lenses, and for foods that require a clean sanitary environment.
