LED Driving Light Manufacturers
Led Driving Light Manufacturers offer auxiliary LED lights that are mounted on the front of a vehicle to illuminate objects and terrain that are not directly visible to the driver. They are commonly used on 4wd vehicles to improve visibility during nighttime off-roading and high-speed cruising.
Several factors affect the performance of an LED driving light. First, look for a model that uses quality chips. Higher-quality LED chips have a more consistent color temperature and better Colour Rendering Index (CRI).
LED driving lights come in a wide variety of lumen packages, beam characteristics and colour options, which makes it important to understand what you’re buying before you purchase. Some lights are designed for a wide or flood pattern, while others have a more focused spot pattern that’s ideal for driving on rural roads or in foggy conditions.
The brightness of a LED driving light is determined by the amount of current that flows through it. The more electrons filling holes in the diode, the brighter the LED will be. The key is to ensure that the heat output and drive current are properly controlled in order to achieve maximum brightness.
When evaluating the brightness of a LED driving light, be sure to look for a raw Lumen figure as well as an effective Lumen figure that has been tested using LED Off Road Driving Lights high-tech photometry equipment. One Lumen per square metre is the standard, and a quality manufacturer will submit their products to professional third-party testing for this purpose. It’s also important to note that a higher number of Lumens does not necessarily mean better light output.
Having durable LED driving lights is important, especially when relying on them to illuminate the road ahead. The light’s mounting bracket and lens need to be strong enough to withstand vibration, corrosion, UV degradation and impacts. It’s best to find one that utilises aluminium for its durability and thermal conductivity, as well as a hard-coated polycarbonate lens that resists stone chips.
The quality of the solder and its creep resistance is also key. Vehicles travelling at high speed and on off-road terrains cause repeated, high amplitude vibration that can cause stress on the solder joints. This can result in failure and loss of light output.
A good indicator of quality is the luminosity or ‘lumens’ rating. Lux measurements are expensive to perform and not all manufacturers report them. However, the better ones will submit their lighting to an independent testing lab and publish the results. This ensures transparency for their customers. For example, Narva’s Ultima LED 215 MK2 LED driving light boasts 165W and 21,780 raw lumens. This equates to a single lux at 1,093 metres.
The top LED Driver Manufacturers ensure that their products are compatible with a wide range of LED setups. They also invest in rigorous research and development to design drivers that offer optimal efficiency and longevity.
One of the most important considerations when choosing a LED driving light is its power factor (ratio of actual current utilized to power delivered) and flicker control. Flicker is a result of high-speed switching operation which creates a significant amount of electromagnetic interference that needs to be filtered and screened using additional circuitry.
Linear drivers implement a non-isolated topology that can be dangerous and does not prevent direct contact between the high voltage output and the AC mains supply. SMPS LED drivers, on the other hand, use surface-mount driver ICs that can be mounted directly onto the metal core printed circuit board (MCPCB) without the need for circuit routing. These drivers feature advanced buck, boost, or buck-boost switched mode power conversion topologies to meet the varied drive current requirements of LED luminaires. This allows for a smaller physical size and improved reliability, EMI suppression, thermal management and input/output isolation.
Despite their small size and light weight, LEDs must still be protected against moisture, dirt, contaminants, insects and dust. Therefore, the mounting bracket is a crucial part of the overall construction. A quality driving light will use a thick bracket made of high-grade metal to withstand repeated, high-amplitude vibration.
The design of the reflectors is a key factor in converting the raw light output of the LEDs into a beam pattern. A cheap light may be powerful in terms of lumens, but due to poor reflector engineering much of that power will be wasted. A well-engineered reflector can provide fine control over the distribution of the light and maximize the use of the available lumens.
Another factor in the security of a LED driving light is the choice of materials for the lens. It is advisable to choose a light that uses polycarbonate rather than cheaper Polymethyl Methacrylate (PMMA) as the latter is less resistant to damage from rocks, road debris and other environmental factors. A good quality light will have a coating that increases resistance to UV degradation and scratches.
A quality LED driving light will have a thick mounting bracket. This is to ensure that the light can withstand the stress of the vibrations caused by high-speed driving. The bracket should also be made of a material that can resist stone strikes, such as polycarbonate. Polycarbonate is more durable than the cheaper alternative of polymethyl methacrylate (PMMA).
The quality of reflector engineering and construction can significantly affect how well a lighting system can project a beam. Poor reflector engineering may cause the light to have an inefficient pattern, with much of its Led Driving Light Manufacturers power wasted. In contrast, a high-quality reflector will efficiently utilise the lumens produced by its LED chips.
Interior car lights that flash, change colors or are particularly bright can distract drivers and potentially impair their ability to see the road ahead of them. This is why many states impose restrictions on the use of these lights. For example, red lights must be visible only from the rear of a vehicle, not from the front, to avoid confusion with emergency vehicles. It is important to check whether a state you are importing your product to has these same safety requirements.
