North America leads the plasma lamp market and is expected to lead in the coming years also. Building owners, government, utilities and other shareholders in the region are supporting the employment of plasma lamps on wider scale due to concern regarding energy consumption. The Asia-Pacific plasma lamp market is expected to grow with the highest rate in the coming years due to high growth potential in the industrial and commercial application of plasma lamps.
The plasma lamp market is growing at a significant rate due to power savings with the use of plasma lamps, long term savings and benefits, highest scotopic luminosity compared to any other lighting solutions, and longer lifespan of plasma lights compared to conventional lighting solutions. Increasing demand for energy efficient lighting systems, and development of wireless technologies for smart lighting systems are some of the factors creating ample opportunities for the plasma lamp market to grow in the coming years.
Plasma lights offer the fullest spectrum of lighting and work through light emitting plasma bulbs which energize a quartz bulb to generate solid state light source. Usage of plasma lamps can save more than 40% of energy, which in turns save more than one-third of the electricity bills. Plasma lamps provide full spectrum light with maintaining the level of efficiency and removes the limitation of dealing with a limited LED spectrum. Moreover, plasma lamps are twice as efficient as LED bulbs available in the market.
Previously, the major drawback in plasma lamps was that the lifespan of plasma lamps was limited by the magnetron used for generation of microwaves. But with the use of solid state chips to produce radio frequency, the lifespan of plasma lamps increased to a significant level. To energize plasma lamps in a bulb positioned inside, a system was designed to focus radio frequency waves into a dielectric waveguide produced by ceramic. The light produced by the plasma gets trapped inside the opaque ceramic waveguide, creating an issue with ceramic waveguide. Ceravision Limited launched an optically clear quartz waveguide in 2009 to overcome the issue with ceramic waveguide.
The plasma lamps can be sustained at powers less than 100 watts with the use of high dielectric waveguide. Plasma lamps also use the fill materials of conventional gas discharge lamps to eliminate the requirement of spinning the bulb. A system, high efficiency plasma lighting, with efficiency more than 80 lumens per watt was introduced; which has proved to be the most energy efficient light sources for industrial, commercial and outdoor lighting. The augmentation is not just because of their high system efficiency, but due to the fact that they enable great luminaire efficiency due to the small light source.
Some of the factors driving the plasma lamp market are less heat emission compared to other light sources and less energy consumption to get the same visual acuity. High cost of plasma lamps and numerous substitutes available in the market at cheaper rates are some of the factors restraining the growth of the plasma lamp market.
Some of the competitors in the global plasma lamps market are Ceravision Limited, Plasma International GmbH, Solaronix SA, Hive Lighting, Inc., Lumartix SA, Topanga Technologies, Inc., and Luxim Corporation. Ceravision Limited had recently launched a combined luminaire and lamp, Alvara, to be used in street lighting applications.
