The LED System comprises of various elements on which need to work in

harmony to drive the best results. At COMPACT, we ensure that all these

components work seamless to define the best performance

Components of LED System

LED: Good quality LED is defined by the following parameters

•Lumen depreciation: At COMPACT we use LED with high Lumen maintenance ensuring

that Lumen depreciation is not more than 30% over the rated life of the LED. These are

certified under the IES LM-80 standards

•High Lumen efficiency: LED with high lumen output are used to ensure higher lux in the

fixture

•Consistent binning: LED colour and quality consistency is ensured through effective

binning.

Components of LED System

Electrical: Good Electrical circuit is the backbone of the LED system

•Optimum Input Current: Operating LEDs at high electrical currents creates higher heat

levels which compromise the lifetime of the LED. Optimum input current ensures long

lifespan of LED. Our circuit design ensures that the LED is driven at optimum current

levels.

•Withstand Surge voltage: Electrical circuit can be the weakest link in the LED system if

its not able to withstand surge Voltage which routinely inflicts the Indian power system.

Our circuit design ensures that the electrical system is able to withstand double phase

voltage without failing or affecting the LED.

Components of LED System

Mechanical/Thermal: Proper Thermal management for enhanced LED lifespan

•Heat Sink: A heat sink is a passive heat exchanger that cools a device by dissipating heat into the

surrounding medium.

•In COMPACT fixtures aluminium fins maximize the surface area in contact with the cooling medium-

air.

•Thermal Interface: Heat sink attachment methods and thermal interface materials also affect the die

temperature of the integrated circuit. We use high quality Thermal adhesive which improves the heat

sink's performance by filling air gaps between the heat sink and the device.

•Pure Aluminium Fixture: Aluminium fixture helps conduct part of the heat generated by chip to the

forebody of lighting fixture . We use high thermal conductivity aluminium which has 50% higher thermal

conduction property.

LED Vs OTHERS Technical comparison

WHY LED IS THE BEST TECHNOLOGY FOR STREETLIGHT

1)    Luminaire/ System efficiency2)    Ballast and Driver efficiency3)    Scotopic superiority4)    Lumen Maintenance5)    Uniformity of light distribution and light hotspots under traditional lights6)    Color reproduction

Luminaire/System Efficiency

In a traditional bulb (incandescent, metal halide, HPS etc.) a considerable portion of the light output is directed upwards. This light must then be reflected down. The efficacy of the reflector in turn is determined by the quality of finish, operating conditions and ambient temperature. The quality of the reflector and, therefore, the amount of light reflected degrades over time. The actual amount of light coming out of a fixture is, thus, considerably lower.

An HPS lamp has a larger profile, a single source of light and a considerabel amount of light trapped in the relector.

An LED light by contrast has a small profile, several sources of light ensuring better light distribution. All the light is produced and directed downwards. There are no problems of reflector efficiency, aging of reflector coating and consequent loss in light output.

Luminaire/System Efficiency

A colleague sent the two pictures above. The image on the left shows illumination of a street with HPS lights while that on the right shows the impact of LED street lights. Several advantages of LED lighting systems are immediately visible. LED lights have significantly less glare, more uniform Light distribution, fewer shadows, and improved visibility. The best part is that this improvement is obtained with fewer lumens and 40 % or more savings in electricity and maintenance costs.
