Energy Efficient and Sustainable Lighting Solution
|
|
An Introduction
Lighting of outdoor areas including industrial peripheral areas, warehouses, streets, roadways
parking lots, pedestrian areas, landscaping, townships, etc. is currently dominated by Metal
Halide (MH), Mercury Vapor (MV) and High-Pressure Sodium (HPS) sources. These non-
energy-efficient light sources have been in use for many years and have well-understood
performance characteristics. Recent advances in Ceramic Xenon technology have resulted in a
new option for outdoor area lighting, with several potential advantages over MH and HPS
sources. Well-designed Ceramic Xenon outdoor luminaires can provide the required surface
illuminance using less energy and with improved uniformity, compared to MH, MV and HPS
sources. Ceramic Xenon luminaires also have significantly longer life (16,000 to 18,000 hours
or more, compared to 6,000 to 8,000 hours) with better lumen maintenance. Ceramic Xenon
Lamps do not contain any mercury, lead, or other known disposal hazards; and they come on a
relatively shorter pulse start with a very less delay time.

2. Quality of Light
The Ceramic Xenon Lamp meets the current outdoor lighting needs. Ceramic Xenon with its warm
Daylight light improves the appearance of retail, shops, business, roads, vehicles, signage, buildings,
parks and the people. Daylight light improves the visibility of objects and people either indoor or
outdoor at the sides of the road and highways. For example, to a motorist this means a better chance
of spotting and reacting to potential hazards on the side of the road, footpaths, bicycle lanes, etc.
Daylight light is perceived brighter than yellow light at the same measured luminance. This is due to
two factors: the eye’s increased sensitivity to white light at low light levels and improved color contrast
from better color rendering. So simply put, you can see much better. Daylight light is always preferred
at night over yellow-orange light of a HPS. Daylight light gives one a better visibility to see objects,
people, and bright, colorful surroundings clearly. It also enables better orientation and quicker
identification of people and the surrounding areas.
3. System Efficiency
The Ceramic Xenon may cut the cost of the total lighting ownership in three ways: increased luminous
efficacy, reduced ballast losses, and improved optical performance.
Increased luminous efficacy:
Improvements to lamp arc tube design and a technology based upon xenon gases has increased
luminous efficacy, meaning that one can use the Ceramic Xenon to replace High Pressure Sodium
(HPS), Mercury Vapor (MV) or Quartz Metal Halide (QMH) with useful energy savings and without
loss of light levels.
Ceramic Xenon can be considered in the following way:
• Ceramic Xenon 35W instead of HPS/QMH 70W.
• Ceramic Xenon 50W instead of HPS/QMH 150W.
• Ceramic Xenon 70W instead of HPS/QMH 150W or 250W.
• Ceramic Xenon 100W instead of HPS/QMH 250W or 400W.
• Ceramic Xenon 150W instead of HPS/QMH 400W.
4. Optical Efficiency
Improved optical performance:
The Daylight light and optimized design and precise positioning of the light source enables
substantially improved optical performance. This means your luminaires can be spaced at a greater
distance apart—one needs fewer light points to achieve the desired lighting performance.
5. Dependable Service
Constant light output over a long period of time for more lamps:
The Ceramic Xenon lamps have a long rated average life of 15,000 hours with shorter cold and hot
start-up time. Solid cool down, ensures the best luminous flux maintaining rate thereby reducing the
early failure of the lamp. The lamp has very few solder joints and a strong outside structure, stronger
anti-vibration and anti-shock ability, thus reducing its early failure possibility.
6. Sustainability
Environmental Concerns and Solutions:
• 20% of the world’s energy costs are towards Lighting.
• Lighting consumes approximately 17 - 20% of energy requirements.
• Sustainable energy efficient lighting reduces global warming by reducing energy requirements.
• More than 80% of current lighting in use in the world is based on antiquated technology which
consumes more energy and indirectly causes more CO2 emissions.
• Even if we convert 20% of the current lighting to energy efficient lighting, we will save nearly
50 Billion Euro globally in energy costs.
• Energy-efficient general lighting has the potential to achieve average energy savings of 40%.
Globally this would save:
o EUR 120 billion in energy costs
o 630 million tonnes of CO2
o 1,800 million barrels of oil equivalent
o Or the annual output of 600 medium sized power stations at 2TWh/yr.
• Hazardous materials in lamps (Mercury) also have to be kept within limits to prevent polluting
our ecosystems.
• Latest lighting solutions can help save our environment.
Elements of Sustainable Lighting:
Most efforts in Lighting are starting off with the need to comply
• Energy Efficiency
o Meeting or exceeding visual performance while optimizing energy utilization (i.e. Lumens/watt)
• Impact on Physical Environment – Life Cycle Assessment (LCA)
o Lighting products have the least impact on the physical environment at optimum
performance levels.
• Light Pollution
o Encroachment/Negative impact of lighting on night skies.

• Ceramic Xenon Lamp has the following certifications from the principal manufacturer:
Electronic Ballasts for Ceramic Xenon Lamps
In recent years there has been an increase in the use of electronic ballasts to operate
various types of High Intensity Discharge (HID) Lamps– High Pressure Sodium (HPS),
Metal Halide (MH) and Mercury Vapor (MV).
As opposed to the magnetic ballast which requires the addition of a capacitor and an ignitor, the
electronic ballast is self-sufficient. With the increasing use of these electronic ballasts, it is important
to understand both of these technologies, i.e. the magnetic and the electronic.
In order to clarify the understanding, we have outlined the significant advantages of Electronic
Ballasts for Ceramic Xenon lamps.
Advantages of Low frequency Electronic Ballast Technology
• Improves the overall efficiency of low wattage systems.
• Specific operating frequency. It can eliminates stroboscopic of light sources and bring comfortable lighting effects.
• A single unit replaces three components: ballast, capacitor and ignitor.
• Protects against voltage and current transients and lamp malfunction (e.g. DC effect near end-of-life).
• Stable light output.
• Stable watt output despite AC line voltage fluctuations. Provides noticeable stability and consistency in lamp to lamp color, stable lumen output, and permanent bright lighting effects.
• Low power consumption, less heat dissipation, effectively reduced energy consumption and electricity charges of lowering down the ambient temperature.
• Rated life up to 50,000 hours
• Power factor very close to 1.0.
• Lamp-friendly ignition process.
• Perfect square wave lamp current: increases longevity and improves lumen maintenance.
• Option for lamp monitoring and control.
