Energy Efficient Lighting


 

 

Echelon’s concern with energy efficient lighting focuses on the areas where we can bring some considerable insights - namely Traffic Engineering Control and Technology. The technologies that we have focused on include:

LED based Traffic Signal lamps can reduce energy consumption related to traffic signal operations by up to 85%. In addition, the life of the LED based lamps is 3 to 5 times that of the standard incandescent lamp. The energy savings and reduced maintenance costs plus improved safety mean that a retrofit can usually pay for itself in 12 to 24 months.
Most street and area lighting in North America use High Pressure Sodium (HPS) and Metal Halide (MH) lamps. These lamps require a typical magnetic or core and coil ballasts to control start up voltage and current to the lamp. This is accomplished with a capacitor, starter or igniter and coil. A typical 100 Watt HPS lamp consumes about 125 watts for normal operation. A  revolutionary new Electronic ballast replaces all the standard parts of the core and coil unit - with one assembly and it only requires 85 to 100 watts for normal operation. This means a 25% to 35% savings in energy consumption with no reduction in light output. Hum and “cycling” are also reduced. Dimming of the lamps can also be effected for those applications where this is feasible.

Savings in energy costs and reduction in maintenance costs usually mean that the conversion cost (of a retrofit) can be paid back in two to four years depending on the cost of power and the wattages of the lamps used.

The LED lamps for Traffic Signals and the new Electronic Ballasts can provide a municipality or region with the tools to reduce power consumption and maintenance costs related to transportation.
