System. With a simple magnetic attachment, beam shapes and colour temperature can be modified, allowing endless design and display possibilities.


Soraa’s LED lamps are compatible with a very wide range of dimmers, having been tested and characterized extensively through its Works with Soraa program. And the company’s novel heatsink design and thermal management system allows its lamps to run cool and deliver efficient light intensity over a long period of time.


Soraa Vivid 2 lamps


The new 4000K and 5000K CCT, full visible spectrum Soraa Vivid 2 LED MR16 renders colours and whites exactly as they would appear in natural light; without the high heat/UV emissions associated with CMH/halogen lamps and beam striations, artefacts or multiple shadows visible in other manufacturer’s LED products.


“With Soraa’s LED lamps, you can create a perfectly lit - yet energy efficient - space. Our full spectrum technology renders colours vividly and whites accurately; our single source LED and innovative optics create perfectly uniform beams of exceptionally high intensity light, casting clear single shadows; and our lamps are ideally suited for fully enclosed, non-ventilated fixtures - a place where other LED lamps struggle to perform,” says Jeff Parker, CEO of Soraa. “And now with our 4000K and 5000K products, you can bring the energizing feel of natural light indoors without sacrificing light quality and compatibility.”


In certain environments, higher correlated colour temperature light is preferred because it helps create an engaging and energising environment. However, because of their broken spectra, LED and CMH lighting products of 4,000K and 5,000K CCT create spaces that feel unnatural and cold.


The Soraa Vivid 2 MR16 solves this trade-off by representing every visible colour in the right proportion, resulting in scenes that feel energizing, yet warm and natural. The full visible spectrum emission of these LEDs results in a CRI of 95 and R9 greater than 90. Plus, the violet component of the spectrum makes whites stand out in their natural brightness and tint.


Soraa’s LED lamps are available in 12V and line voltage configurations, as well as in a wide range of colour temperatures (2700K, 3000K, 4000K, and 5000K) and beam angles (10°, 25°, 36°, and 60°), allowing lighting flexibility for any type of indoor or outdoor environment.


This includes lighting suitable for smooth and textured fabrics, gold, diamonds, skin tones, and a broad array of other applications. The company’s narrow 10° lamp works with its award-winning magnetic accessory SNAP

The devices come in a smaller, thinner package produced in high efficiency production lines (SO6 and SO4) and have a high CTR at low input current of 0.5mA.


Toshiba launches family of transistor output photocouplers


The devices significantly help to reduce power consumption for industrial devices such as LEDs


Toshiba America Electronic Components, Inc., (TAEC) has introduced a new family of low input current-type transistor output photocouplers that offer a high CTR (Current Transfer Ratio) at low input current.


The TLP182, TLP183, TLP292, and TLP293 significantly contribute to a reduction in power consumption by reducing the LED current of the photocoupler.


Available in both SO4 (TLP292 and TLP293) and 4-pin SO6 (TLP182 and TLP183) packages, by employing Toshiba’s original high-output LED, these products provide not only a high current transfer ratio at the conventional input current of 5mA, but also at the same current transfer ratio at the low LED current of 0.5mA.


This makes it possible to minimize the current to the LED and therefore reduce power consumption.


The TLP182, TLP183, TLP292, and TLP293 also support operation at up to an ambient temperature of 125 degrees C, making them ideal for use in industrial devices such as PLCs and inverters, compact power supplies, AC line detection for household appliances, and other devices operating in extremely hot environments.
