LED Driving Lights
The makers of LED driving lights don’t manufacture the bulbs or LEDs themselves, they assemble them using mounts, circuit boards and reflectors. That’s why you see companies quote raw lumen figures that don’t really mean much.
The SMPS drivers are favoured by manufacturers because they offer high power efficiency, controllability, flicker elimination, low total harmonic distortion (THD), and AC mains isolation.
Light output
LED driving lights are a great way to improve your visibility on the road. They are highly efficient and offer a long lifespan. They are also extremely durable, withstanding vibrations and heat. You can choose from a wide range of colors and styles to match your vehicle’s style. The most popular LED driving lights are those with a high lumen rating. This measure is a standard for the brightness of a light and is measured in candela per square centimeter (cd/cm2).
An LED driver regulates the current supplied to an array of LEDs, avoiding thermal runaway and maintaining a consistent light output. This is achieved by converting the alternating current (AC) input into Led Driving Light a DC output that is suitable for driving an LED array. The driver does this by regulating the voltage along an electronic circuit and supplying it to the LED array.
SMPS drivers are the preferred LED driver solution in visually demanding and safety sensitive indoor lighting applications, where efficiency, lighting control and flicker elimination are critical requirements. They use a switched linear topology that offers a compact design with minimal component count and reduced total harmonic distortion (THD). Unlike buck LED drivers, they do not require a separate power supply and are fully isolated from the AC mains.
Color temperature
If you’re planning on buying LED driving lights, it’s important to know about color temperature. This is because different light temperatures affect how well they illuminate a space. Some light colors are more natural, while others are brighter and cooler. It’s best to choose a light color that matches the overall tone of your room. For example, if you have more silver and blue tones in your home, cool white LEDs are ideal. Warmer, natural colors like yellow and gold are better suited for interiors with wooden accents.
The color temperature of a LED light is measured in Kelvins and represents how bright it appears to the human eye. The lower the number of Kelvins, the warmer or more yellow the color is. The higher the number of Kelvins, the cooler or more blue it is. For a more accurate picture of the brightness, look for LEDs that display an effective lumen figure. This figure is calculated through high-tech photometry and is the most realistic representation of the light output.
A good rule of thumb is to stick with a color temperature that is closest to the natural Daylight. This will give you the most visibility while driving. It’s also important to choose a constant voltage driver over a SMPS driver. SMPS drivers use a large amount of reactive components, which can increase the size and cost of your system.
Reflectors
The reflectors of a led driving light are used to direct the beam of light from the source. They are available in many shapes and sizes, allowing them to be adapted for different applications. The shape and size of the reflector determines the angular Led Driving Light distribution of the beam of light and its efficiency. Lighting designers specify the efficiency of a reflector in units of candelas per steradian.
PIAA’s new rearward-facing LED lights use an advanced computer-designed multi-surface reflector that gathers and projects more light than traditional forward-facing bulbs. They also offer better control of the LED lighting beam pattern, reducing glare on other vehicles and road users.
Another factor that affects the performance of a LED driving light is the brightness, or lumen, rating. A higher lumen rating means more illumination, but not necessarily greater accuracy. A lumen rating is based on the amount of light that a single LED emits, and it does not include the power consumption of the fixture.
A good LED driving light will have high lumens, but the actual number of lumens depends on a number of factors, including the size of the LED and its packaging. It is important to look for a driving light that has an accurate lumen rating, especially when shopping online. A reputable brand will publish the lumen rating on their website, making it easy to compare LED driving lights and make an informed purchase.
Dimming
If you’re concerned that your LED driving lights are getting dimmer, you can test the bulbs with a voltmeter. You should also check the wiring and ballast to make sure they’re all connected properly. If the problem persists, it could be a sign of a burned out bulb or malfunctioning driver. In such cases, you should replace the bulb or ballast to resolve the issue.
If your LED driver isn’t designed to dim, it may overwork itself by trying to maintain a constant current. This will cause it to fail over time. If you want to make your LED driver dim, look for a model that is designed with a PWM dimming control. The dimmer function is usually generated by a timer IC, such as the popular TI 555.
Most LED drivers use AC power, but some offer DC inputs as well. These are called off-line LED drivers. They can operate with a wide range of voltages, but they’re generally more expensive than their DC counterparts. This is because they have a larger physical size and require more components. They also create more electromagnetic interference, which needs to be filtered and screened using additional circuitry.
