lighting can be manipulated to illuminate the curves in the road

Through Pixel Light, it’s possible to generate any particular beam-shape required to assist with the driver’s visibility. Discrete LEDs are turned on, off, or dimmed to form the most suitable beam at any stage of the journey. When combined with the vehicle’s navigation system, lighting can be manipulated to illuminate the curves in the road, as well as raise or lower when negotiating hills. This technology, when linked together with camera systems, also enhances illumination of road signs, pedestrians, and other objects in the driver’s line of sight, while minimizing the glare of oncoming traffic.Vehicle lighting has gradually migrated from xenon-based lamps to solid-state technology over recent years. Initially, the changeover concentrated on areas such as cabin illumination, parking lights, etc. More recently, though, it’s being used in the front lighting of mid-/high-end car models (and now becoming an option in lower end cars). Two main reasons behind the switch are the greater reliability and lower power consumption offered by LEDs. However, perhaps the overriding benefit is the lighting system’s versatility made possible by the LED’s adjustable output power, which can ultimately have a profound effect on automotive safety.
Pixel led high bay light and fast switching means that multiple blanking zones are able to be placed into the beam. The beam can be shaped or bent as required with a higher level of precision and without the need for shaping or bending motors, thereby simplifying system design and lowering the overall bill of materials.The variation in the electrical characteristics of each LED has a significant impact on lighting-system performance. For example, a considerable difference in the LEDs’ anode-cathode voltage can trigger high levels of heat dissipation, which raises power consumption and requires additional heatsinking. Until better LED matching becomes available, this topology will likely experience only limited success in AFS applications.Short-circuit switches disable individual LEDs so that the beam can be shaped as needed. It’s possible to avoid the power-consumption and thermal-management issues inherent in parallel topologies with system partitioning, if a companion chip is added into the circuit.

The first family of mid-power ceramic LEDs that offer no-compromise performance and reliability. Unlike today's common mid-power plastic packages, XLamp XH-G and XH-B LEDs enable lighting manufacturers to create a new generation of more energy-efficient, longer life LED lighting solutions without sacrificing cost or performance. XH LEDs are optimized for fluorescent replacement lighting applications such as troffers and panel lights, where high efficacy, lifetime and smooth appearance are critical.We're excited that Cree is offering high-quality, ceramic-based mid-power led flood light designed for real world lighting applications," said Roger Suen, supply chain management director, Light Engine. "The XH LED family gives us confidence in providing products that deliver stable lumen maintenance and good color consistency that cannot be duplicated by plastic packages.
