Have you ever suffered from the harmful impact of voltage spiking in your car’s electrical setup? Furthermore, has your car’s LEDs failed just after few months of their installation? If yes, then there is a high probability that you are a victim of voltage spiking.
Voltage spikes can be found in almost every truck or car. Although, there are a number of reasons why it occurs; however, most of them arise from the alternator, which is the electrical power plant of your car. An alternator is responsible for charging your car’s battery and supplies sufficient power for the working of all electronic equipments of your car. Though, the car battery is DC in nature (12 V generally), the alternator supplies an AC voltage.
Thus, a rectifier is fitted in the car, which carries out the AC to DC voltage conversion. A rectifier can be built separately or can be fitted as the part of the alternator. Depending upon the car’s demand, the specific load is levied onto the alternator. The load on your car keeps on changing. You can easily witness such changes during the night while waiting at the traffic signal. The continuous modulation in the power levels result in the generation of spikes and dips in the voltage, which over time accumulates to degrade the performance of the LEDs.
However, with the recent technological advancements, this type of LED failure is becoming obsolete now. With the incorporation of the latest techniques, a separate regulated supply of power is provided on all LEDs, thereby making them less susceptible to voltage spiking failure. However, where does the main difference lie between the conventional and the technologically advanced voltage spike tolerant LEDs? Read below to spot the major differences:
Although, a conventional high power LED comes with a lot of valuable advantages like affordable price, wide application area, brighter output, beautiful colors, etc., the only feature that holds back the efficiency of them is the power regulating circuitry, which controls the power supplied to the individual bulbs. The inefficient division and regulation of voltage in the series connected LEDs leads to overheating and thus results in premature failure of the lights.
On the other hand, high power LEDs come with a separate power supply, which maintains a consistent voltage to the individual illuminations, without affecting the brightness of the lights. In some lights, even the bridge rectifiers are incorporated for enabling the use in dual polarity mode. These LEDs encompass the ability to light up, irrespective of the polarity they are connected in.
