The LED has been established as the lighting technology of choice for the commercial vehicle industry due to its numerous benefits over incandescent lighting.<\/span><\/p>\n

The light emitting diode (LED) has established itself as the lighting technology of choice for the commercial vehicle industry. Decades of technological advancement of LEDs have seen traditional incandescent lighting phased out on commercial vehicles. With uptime as the driving force behind most vehicle specification considerations, LEDs have proven more reliable, durable, and longer-lasting. There are numerous benefits LEDs can offer and understanding these benefits can help fleets capitalize on cost savings and uptime.<\/span><\/p>\n

Electroluminescence versus incandescence<\/span><\/h3>\n

LEDs utilize electroluminescence to create light.<\/span><\/p>\n

\u201c[The process of] electroluminescence [in LEDs] is the movement of electrons between two terminals of a diode,\u201d says Dan Wallace, National Sales Manager, OEM Trailer Group, with Phillips Industries. \u201cThe LED is a diode itself. The power goes into the LED which has semiconductors. As the power flows back and forth between the semiconductors, it produces light.\u201d<\/span><\/p>\n

Phillips Industries is a manufacturer and supplier of a variety of commercial trucking parts, serving both OEMs and the aftermarket.<\/span><\/p>\n

\u201cThe energy that is lost during this process as it goes between the conductors creates the light that you see, and you actually see a color,\u201d Wallace continues. \u201cThe color is based on how much energy is lost. You can see red, yellow, blue \u2013 really any color in the rainbow.\u201d<\/span><\/p>\n

The process of incandescence, or light produced from heat, was utilized in commercial vehicles before LEDs were integrated. With incandescent bulbs, power is sent to a metal filament; the filament is heated and begins to glow, emitting light. In order to obtain different coloring from incandescent bulbs, a colored lens is placed over the bulb.<\/span><\/p>\n

The light-emitting processes and construction of incandescent bulbs and LEDs are the main differences between what these types of lighting can provide a commercial vehicle.<\/span><\/p>\n

The benefits of LEDs<\/span><\/h3>\n

LED construction is referred to as a solid-state, being a circuit that is electronically powered.<\/span><\/p>\n

\u201cThe benefits of LED lighting are innumerable, though the primary among them is that the solid-state nature provides a lifetime lighting solution,\u201d says Andrew Liuzzo, marketing communications specialist, Truck-Lite. Truck-Lite designs, manufactures, and distributes vehicular safety lighting and visibility products.<\/span><\/p>\n

The longevity of LEDs is superior compared to incandescent bulbs.\"ThisThis chart compares estimated service life and pricing ranges for incandescent and LED lighting in key areas of Class 8 trailers.<\/span>Image courtesy of Optronics International<\/span><\/span><\/p>\n

\u201cLED lamps, being a solid-state, are extremely robust and resilient,\u201d says Brett Johnson, president and CEO of Optronics International, a worldwide manufacturer and supplier of industrial and commercial vehicular safety lighting products. \u201cIncandescent lights generally have a service life of about 2,500 hours [as it pertains to the commercial vehicle], whereas the solid-state LED has a service life of up to 100,000 hours.\u201d<\/span><\/p>\n

A major reason for the extended life, beyond its solid-state construction, is the amount of amperage drawn to power the LED.<\/span><\/p>\n

\u201cGenerally speaking, an LED lamp draws about one-tenth the amperage of an incandescent lamp,\u201d says Phillips Industries\u2019 Wallace. \u201cAn incandescent stop\/tail\/turn light with a 1156 bulb draws 2.1 amps. The equivalent stop\/tail\/turn LED lamp draws 0.2 amps.\u201d<\/span><\/p>\n

The reduction in resistance provides the vehicle\u2019s electrical system relief. The lower current draw may also result in increased battery and alternator life for the vehicle, as well as more power available for the vehicle\u2019s other electrical demands, says Liuzzo.<\/span><\/p>\n

Furthermore, less amperage requirements for the lighting allows for the specification of smaller gauge wiring. Instead of a 12-gauge wire, LED lighting systems can utilize a 14- or 16-gauge wire, Wallace says. The smaller gauge wire equates to less copper in the harnessing, which yields a lower cost.<\/span><\/p>\n

Durability is another benefit LEDs offer.<\/span><\/p>\n

\u201cIn heavy duty or vocational applications in which there are rugged environments, the solid-state circuit of an LED is significantly more rugged and durable,\u201d says Optronics\u2019 Johnson.<\/span><\/p>\n

Without a filament that can become disconnected and cause the light to fail entirely, like that in an incandescent bulb, the LED\u2019s circuit construction has a stronger and longer-lasting design. And as LED technology has progressed, the size and durability of the lamps have improved.<\/span><\/p>\n

Phillips Industries has developed PERMALITE XB, a circuit board-free LED system. The system features copper strips which contain the LEDs; these strips are insert molded into the base of the lamp. The lamp has a lens molded to the base as well. This system creates a fully encapsulated light, eliminating airspace between the LED and the lens.<\/span><\/p>\n

\u201cIt is highly impact-resistant, [as well as] resistant to corrosion, vibration, and water intrusion,\u201d Wallace says of PERMALITE XB lamps. \u201cThey are lightweight and extremely thin.\u201d<\/span><\/p>\n

Maintenance practices with LEDs<\/span><\/h3>\n

Preventive maintenance (PM) is a great way to monitor the life of LED lamps and ensure the fleet capitalizes on the longevity such lights offer. The number-one cause of problems for LEDs is corrosion, so monitoring for corrosion is essential.<\/span><\/p>\n

Optronics\u2019 Johnson recommends drivers and maintenance personnel frequently check the lighting system to ensure lights are functioning properly. Furthermore, Truck-Lite\u2019s Liuzzo suggests an LED be replaced should a single diode malfunction. Many LED manufacturers have extensive warranty coverage for LED lamps \u2013 be sure to check if the light is under warranty for replacement.<\/span><\/p>\n

When monitoring LED functionality and health, it is crucial to consider the electrical system as a whole. A failure in the LED may be indicative of a failure in a wiring harness or elsewhere in the electrical system. Truck-Lite offers the Light-Out Detection System for LED lighting that diagnoses light failures as well as harness and connection failures.\"After<\/span><\/p>\n

\u201cThe longer you can maintain the integrity of a vehicle\u2019s wiring harness, the better your lighting system will perform,\u201d Liuzzo says. \u201cThe use of wire probes to check voltage or continuity should be discontinued, as this practice compromises a harness system. Puncturing wire allows for moisture to wick throughout a vehicle\u2019s electrical system, corroding it from the inside out. Using a multimeter to troubleshoot a wiring harness system is the safest way to ensure the longevity of a harness system without damaging connectors, wires, and seals.\u201d<\/span><\/p>\n

\u201cWe recommend as part of a PM schedule that you unplug and inspect your lighting system,\u201d says Phillips Industries\u2019 Wallace. \u201cUnplug the lights and the mating connections on the harness, apply a coat of dielectric grease, and move on to the next connection.\u201d<\/span><\/p>\n

Lighting the road ahead<\/span><\/h3>\n

Fleets with older vehicles may still utilize incandescent bulbs. It should be known that replacing incandescent bulbs with LED lamps is a viable option. Most LED manufacturers offer multiple connection options to ensure compatibility.<\/span><\/p>\n

Upfront cost in switching from incandescent bulbs to LEDs may be a concern for some fleets. However, with the longer life expectancy of a well-maintained LED system, the price of continuing to purchase and install incandescent bulbs over the same timeframe may be more costly.<\/span><\/p>\n

With a longer lifespan and a greater durability, LEDs may be a more desirable option for commercial vehicle lighting.<\/span><\/p>\n<\/div>\n
