Colour Rendering from LED Lighting | LEDinside – LED, LED Lighting, LED Price Trends, Global LED News and Market Research. Start to look into LED lighting and quickly it becomes obvious that one type of LED will not suit all situations. After a while, you get sophisticated enough to take colour-rendering index (CRI) and colour temperature into account, and even then you are only about halfway down the check list. A little colour science There is no scientific definition of white light because, like beauty, white is in the eye of the beholder. However, everybody agrees that daylight is white, or at least a type of white, and daylight comes from the sun - a ball of gas with a surface temperature about 6,500 Kelvin.
"Sunlight is pretty close to black-body radiation," Dr James Nobbs of the University of Leeds told Electronics Weekly. Nobbs is head of colour physics at a unique institution: Leeds' department of colour science, which was established in the 1880s to support textile dying - a regional speciality at the time. It has a continuous spectrum across the 750nm (deep red) to 380nm (violet) we see in a rainbow. NOVALED - The New OLED Generation. LED professional: LED Lighting Technology Information - Magazine.

Elemental LED Adds New Aluminum Channels for LED Strip Light | LEDinside – LED, LED Lighting, LED Price Trends, Global LED News and Market Research. Elemental LED has added aluminum channels aimed at satisfying demand for stylish LED strip light installation options. The aluminum channels can be available in cabinet installations, display cases and for architectural accent lighting.
Alternatively, channels can be used in conjunction with LED strip light in nearly any situation requiring more durability or the style of a sturdy fixture. According to the company,pairing an aluminum channel with the appropriate strip light choice enables customers to build the perfect fixture for almost any project. The Aluminum Channels are designed for use with flexible LED strip lights. Clear and diffused channel covers provide further customization options. Disclaimers of Warranties 1.

Driving Higher Levels of Efficiency in Lighting through Primary Side Regulation | LEDinside - LED News, LED Price Trends and LED market intelligence,Global LED News, Market Intelligence & Research. Abstract Global attention continues to focus on the methods for achieving low power consumption and high efficiency. Lighting represents nearly 20% of the worldwide consumption of electrical resources and advancements in lighting can have a tremendous impact.
LED solid state lighting (SSL) is environmentally friendly for the global environment. It has a smart form factor, long life, high conversion efficiency, and substantially reduces power consumption up to 80 or 90 percent compared to traditional incandescent lighting. LED drivers play an important role in LED SSLs, as these drivers provide accurate current to maintain a stable brightness. However, the traditional approach of the LED driver used a secondary feedback circuitry for driving LED’s voltage and current. This secondary feedback circuit increases the cost and size. This article shows a patented technology “Primary Side Regulation” (PSR). Figure 1. Figure 3.
Conclusion Disclaimers of Warranties 1. How to choose LED Driver IC? | LEDinside - LED News, LED Price Trends and LED market intelligence,Global LED News, Market Intelligence & Research. LED has established its unshakable position in the backlighting of portable devices. Even in the backlighting for the large-sized LCD panel, it has started to challenge the mainstream CCFL. In lighting, LED is especially popular in the market due to its highlighted features like energy-efficiency, environmental friendliness, long lifetime, and low maintenance. The driver circuit is a crucial and integral part of the LED.
Whether in lighting, backlighting or the display panel, the choice of the technical architecture of the driver circuit must correspond to specific applications. The LED lighting mechanism goes as follows: when the forward voltage is applied to both ends, the minority carrier and majority carrier in the semiconductor recombine to release surplus energy, giving off photons. The main functions of the LED drive circuit are to transfer the AC voltage into a constant power supply and match the voltage and current according to the requirements of LED devices.
