Induction Lamps
Induction is a process whereby the generated power is passed from one circuit to another without the use of physical electrical conductors. Thus induction lamps are also known as ‘Electrode-less’. Induction lamps utilize the same principle as transformers and radio receivers, enabling lamps to be constructed without the need for wire connections to pass through the glass or quartz envelope. This simplifies construction and extends lamp life.
Induction lamps are available as low pressure mercury lamps using the same triphosphor coating of the inner bulb surface. Low wattage versions use integral control gear but the higher power ratings have external control gear. There is also a high pressure discharge induction lamp, which uses sulphur vapour.
As the commercially available range is limited and diverse a summary of typical operating characteristics has not been included.
Induction lamps are virtually maintenance free and offer an ultra-long life time. They give a pleasing light with high visual comfort - offering a range of colour temperatures.
Lamp manufacturers have pursued different variations on the induction theme. Consequently, there are a number of different types of lamp available. Due to them being a specialist lamp, their availability and distribution is limited whilst the purchase price is high.
