LED automotive lighting applications

As far as the luminous efficiency is concerned, the LED has exceeded the incandescent light bulb (the standard 60W bulb output is 15lm/W). Or, in other words, the amount of light output (unit: lumen) that is used to produce a light output from a light source (unit: W) to represent the light output. Even so, it is predicted that by 2012, the light output of 150lm/W LED in the market will be everywhere.

High power or high brightness LED light output has exceeded 100 lm/W / W with significant milestone. In fact, some manufacturers have claimed to have obtained the LED light output of the 200lm/W in the laboratory. Therefore, it is clear that, in terms of luminous efficiency, LED has exceeded the incandescent bulbs (standard 60W light bulb output is 15lm/W). Or, in other words, the amount of light output (unit: lumen) that is used to produce a light output from a light source (unit: W) to represent the light output. Even so, it is predicted that by 2012, the light output of 150lm/W LED in the market will be everywhere.

Another added benefit is the life of the LED. Depending on the way of calculation, the life of white LED bulbs can reach at least 10000 hours, and some even claim up to 50000 hours, while the incandescent lamp life is only about 1200 to 1500 hours.

In addition, LED is a "green" product, because it does not contain any hazardous materials. The cost of LED lighting is falling very fast. In the past 12 months, the price of dedicated white LED (some of which have been used by LED bulbs and account for most of their costs) has fallen below $1 a few years ago to about $5.

LED industry analysts predict that in the next 12 months, the price of replacing incandescent bulbs with LED bulbs will be acceptable to consumers.

Some LED manufacturers claim that they have designed a light emitting chip that can be powered by a LED bulb, which produces light that is comparable to that of most private residential 75W incandescent bulbs. In order to have the ability to output the amount of light, such LED chips typically require power from 12W to 15W. In particular, in the case of a car, the headlights must have at least 800 lumens of light output.

How much fuel can LED actually save? University of Michigan Transportation Research Institute (Michigan 'sTransportationResearchInstitute-UMTRI). In a study conducted in 2008. In that study, they compared 100% systems using traditional incandescent and halogen lamp light source and lighting effects, a 100% model system using LED lighting, power consumption of bus exterior lighting was investigated.

The results show that the energy saving rate of the whole LED system is more than 50%. This not only saves the fuel cost of gasoline powered vehicles, but also will reduce the total carbon emissions of 1% to 2% per year.
