halogen lamp
A halogen lamp is an incandescent lamp in which a tungsten filament is sealed into a compact transparent envelope filled with an inert gas, plus a small amount of halogen such as iodine or bromine. The halogen cycle increases the lifetime of the bulb and prevents its darkening by redepositing tungsten from the inside of the bulb back onto the filament. The halogen lamp can operate its filament at a higher temperature than in a standard gas filled lamp of similar wattage without loss of operating life. This gives it a higher efficacy (10-30%). It also gives light of a higher color temperature compared to a non-halogen incandescent lamp. Alternatively, it may be designed to have perhaps twice the life with the same or slightly higher efficacy. Because of their smaller size, halogen lamps can advantageously be used with optical systems that are more efficient and in architectural lighting it’s recommended applicated for accent and general lighting in homes, recidential building, shops/stores, restaurant/café, also exhibition/art galleries.
There are several types of halogen lamp which are deppend on dimention of the reflector. MR16 is the mostly used and it has low-voltage dichroic reflector type. The dichroic reflector coating transmits the infra-red radiation (heat) backwards through the glass and reflects the visible radiation (light) forward, thus resulting in a ‘cool beam.’ Dichroic reflector lamps are ideally suitable for accent, task and decorative lighting in homes, shops and hotels/restaurants.
