Most typical schemes have a return on investment of less than 2 years. Find out more »

History of Induction Lighting development

1884 - Johann Wilhelm Hittorf discovers the electrodeless discharge lamp, Hittorf is also known for the discovery of the cathode-ray.

1880s - J.J.Thomson thoroughly studies the phenomena of the electrodeless discharge lamp following the initial discovery by Johann Wilhelm Hittorf. Thomson was an established physicist and it was his work that allowed Induction lighting to develop further.

1893 - Nikola Tesla first demonstrated his electrodeless lamp, at the 1893 World Columbian Exposition in Chicago, his lamp looked like a large light bulb and had strange green phosphors. His lamp powered the electromagnetic field of a nearby large “Tesla Coil”. Tesla brought the lamp into the public eye and further improved the lamp.

1904 - Peter Cooper Hewitt developed an Induction lamp that used mercury vapour; he already had expertise as the inventor of the first commercial mercury vapour lamps. He worked on Induction lamps with a sphere shape.

1967 - John Anderson develops the first reliable electrodeless lamp. The lamp moves out of experimental stages and the commercial era of the lamp begins. Later his compact GENURA lamp was released in 1994. General Electric, his employer, applied for 27 patents related to this lamp technology.

1990s - The Philips Corporation develops the QL lamps which operated at a frequency of 2.65Mtz which was not achieved before.

2010 - Cema Lighting Limited partner with an electronics company to develop a fourth generation higher lumen output lamp using a different electronic configuration ensuring greater lamp life and reliability.

2012 - Cema Lighting Limited introduces the UKs first comprehensive five year “Fit and Forget” Induction lighting system, giving customers a five year warranty on both parts and labours, giving a zero cost 5 year lighting system.

2012 - Cema Lighting Limited plans to move all Induction ballast production to the UK and applies for a number of patents on new electronic ballast developments.

The basic principles of Induction Lighting

Our new generation Induction lamp is a brand new form of lighting that applies state-of-the-art technology combining optics, power electronics, plasma study, magnetic material study and other related fields.

The new generation Induction lamp represents the future of lighting, with high lumen output, high
colour rendering and long lamp life. Induction lighting aims to become the most promising energy saving and environmentally friendly light source around.

So how does it work

An Induction lamp only consists of a lamp, a power coupler and an electronic ballast, that is it!

The power coupler is built inside the lamp, connecting the electronic ballast via the feeder line. It induces the high frequency electromagnetic energy, which is generated by the electronic ballast into the lamp. This allows the air inside to be ionised, which then turns to plasma.

As the activated atom of plasma returns to its original state, the plasma will then radiate ultra violet light and activate the phosphor powder coating on the inner wall of the lamp to give off visible light.

History of LED Lighting development

1907 – British scientist Henry J. Round discovers that the junction of a semi-conductor produces light. Silicon Carbide was used but the light was very dim so no further research took place.

1920’s – Russian researcher, Oleg Vladimirvich Losev produced the first LED, but his research never made it out of his own country. At the same time, Bernhard Gudden and Robert Wichard Pohl of Germany, experimented with phosphor materials made from Zinc Sulphide with Copper. These experiments did not produce much light either.

1936 – The term “electroluminescence” came about after a published report by George Destriau on the light produced by passing an electric current through Zinc Sulphide powders.

1950’s – British experiments in electroluminescence using a semiconductor called Gallium Arsenide, led to the development of the first infrared light-emmiting diode. It was reported that these early laboratory LED’s had to be kept in liquid nitrogen during operation and significant effort was required to produce lights that could function at room temperature.

1962 – Nick Holoyak Jr. produced the first visible spectrum light, a red light. Holonyak was later at the University of Illinois, where a student graduate of his, M. George Craford, invented the first yellow LED and later a much brighter red and red-orange in 1972.

1990’s – Experimenters used Indium Gallium Aluminium Phosphide to produce ultra bright LED’s of orange –red, orange, yellow and green. Blue LED’s were also produced in the early part of this decade as well. They were first produced using Silicon Carbide, but due to the dim quality of Light this was replaced by Gallium Nitride. Following this, Indium Gallium Nitride was introduced which produced high intensity blue and green lights.

LED is not as new as most people believe. LED, or light-emitting diode, started out as a very dim, yellow light but progressed to the very bright light we see today.

The portfolio of Cema Lighting Limited LED products has been compiled using the latest LED technology within the lighting field. All Cema Lighting Limited LED products carry a full 5 year replacement warranty. It is envisaged that the new LED products being introduced over the next few months will carry a 7 year warranty. New products are to include an LED tube with an in-built emergency 3 hour system. Also, an LED tube with an in-built movement sensor and lux level.
