Can ultracapacitor be used as a power source for smart street lighting?

CONCLUSION We can use UltraCapacitor as a power source replacing the Battery to achieve a feasible Smart Street Lighting System. Although we need more complex controller that can increase the efficiency of the current proposed setup and we can use soft switching for better performance.[]

Do LED street lights need an AC-DC converter?

LEDs do not have tubes or filaments, making them incredibly durable and capable of operating with the driver for longer periods. An AC-DC converter must be utilized to power LED street lighting systems from the input voltage of alternating current.

What is a street light sensor?

The sensor used has a function to activate the street lights at night and to turn the lights off automatically at daylight. They are Light Dependent Resistors (LDR) with sensitivity from daylight or any means of lighting system .

Why SMD LED is operating when connected to ultracapacitor?

As can be seen that the SMD LED is operating when connected to UltraCapacitor. Although in current setup it can be seen that the capacitor are connected in series which is not an ideal way to connect capacitor. These UltraCapacitors on later stage were connected in parallel as the capacitance increases in parallel. VII.

How much power does a street lamp post consume?

In relation to its power consumption rate, a single street lamp post consumes 0.32kWhr/month. Base from the computation table of MERALCO, this consumption gains an amount of Php108.00 per month. Figure 4: Prototype construction Set-up. Table 1: Breakdown of the material cost.

How does a street light system work?

In relation to the findings, the prototype was constructed with super capacitors, solar panel, and a lead acid 12VDC battery to sustain a stand-alone street light system which operates the entire cycle of its function by generating its own energy and to supply power in the control.
