History Of Induction

Nikola Tesla was a Serbian-American inventor, physicist, mechanical engineer, electrical engineer, and futurist. He was an important contributor to the use of commercial electricity and is best known for developing the modern alternating current (AC) electrical supply system and many revolutionary developments in the field of electromagnetism in the late 19th and early 20th centuries. Tesla demonstrated wireless energy transmission as early as 1891. The Tesla effect is a term for an application of this type of electrical conduction. In 1894, Tesla lights incandescent lamps wirelessly at the 35 South Fifth Avenue laboratory in New York City by means of “electro-dynamic induction” or resonant inductive coupling, providing evidence for the potential of wireless power transmission. It is based on Tesla early discoveries & inventions, that conventional lighting evolved into modern days Induction lighting technology which today contribute to green energy and help reduce carbon footprint globally.

How Induction Works

Induction light is an electrode-less induction lamp consisting of an electronic ballast. Rings with magnetic coils create an electromagnetic field using a high frequency generated by the electronic ballast, providing outstanding energy savings and vastly reducing maintenance costs. This field goes round the glass-filled tube. Electrons discharged by the magnetic coils collide with mercury atoms inside the tube and become excited. These electrons give off energy in the form of invisible UV light. The conversion to visible light occurs when it passes through a phosphor coating on the inside surface of the tube. The lamp therefore relies on the fundamental principles of gas discharge and electromagnetic induction to produce light.

Advantages

Induction lighting’s long operating life means it’s virtually maintenance free and well suited for installation in areas that are difficult or costly to access. Induction light is ideal for use with high-ceiling applications, great for warehouses, storage facilities, industrial buildings, office buildings, school gyms, roadways, parking garages, street lights, park lights, public areas and more.

  • High efficiency (Lamp 80 – 90 lm/W, Ballast PF 98%) – High efficiency of the lamp and ballast leads to energy cost savings
  • Save electricity up to 60% – Less electricity consumption while maintaining higher or equal brightness
  • Long lifespan (80,000 – 100,000 hrs) – Based on usage of 12 hrs per day, Induction Lamps can be used to 20 years!
  • Easy on eyes (No glare and flickering) – Eyes are not easily tired and eyesight is protected. Better consumer experience and increase safety to operators working long-hours
  • Low heat emission (Lengthen lifetime of lighting systems and remove risk of explosion or fire. Reduce HVAC cooling load)
  • Instant turn on and restart (0.01sec) – Unlike metal halide lamps, Induction Lamps will be lit instantly when back-up power kicks in during power failures.
