What's new in the market

Candela Lighting Systems has currently developed a wide range of LED downlights mainly for commercial applications with high luminous intensity power LEDs. This series of downlights is available in the range of 5 W to 36 W, both in recessed and surface mounted versions, using higher amounts of special aluminium as the heat sink. It has also developed LED track lights, especially for retail spaces as a replacement for conventional halogen and metal halide lamp options, with the best quality diffuser.

"We use excellent quality thermally conductive adhesives for the diodes to bond with the heat sinks and the heat sinks to the MCPC boards, both in liquid and tape form, depending on the fixture. We are also very particular about the quality of the aluminium, which helps to dissipate heat, leading to the longer life of the product. Besides, several steps have been taken to control and regulate the current in the power supply for LED products and we have added over voltage protection to the light unit," informs BN Sinha, director, Candela Lighting Systems Pvt Ltd.

Glacial Light offers new advanced outdoor and indoor lighting solutions to cater to the commercial and industrial sectors. A few examples are the triac dimmable downlights of 15.24 cm X 20.32 cm (6 inch and 8 inch), and the new 110 W and 220 W high bay light, which is specifically designed with Philips Lumileds LEDs that use thermal module technology to design heat sinks. "We have used innovative technology to build a new driver, which can save energy transfer losses. This driver is available in our downlights, MR16 and AR111," states Nikhil Malhotra, country manager, India, GlacialTech.

"Our thermal module technology prevents the junction temperature from increasing when it reaches a certain level, which guarantees the quality of our high bay lights and extends their lifespan, while reducing atmospheric heat. There is an inbuilt system for controlling the temperature. With no ultraviolet rays and toxic substances such as lead and mercury, these high bay lights are a perfect fit for high ceiling applications. Our intelligent designs offer maximum light output by using 75 per cent less energy than a typical high pressure sodium metal halide light. We use multi-chip technology, whereas other suppliers use COB (which has heat sink problems), with advanced lens technology," explains Nikhil Malhotra.

Among its new products, Mirc Electronics (Onida) offers LED high bay lights in various models, ranging from 70 W system power to 160 W system power. "Our LED high baylights have various technical advantages. They have better thermal management, as they are perfectly designed with extruded aluminium heat sinks for 100 W and 150 W lamps-keeping LED junction temperatures as low as possible. This makes the product more viable for long continuous runs in rigorous conditions-even up to 10 years," says Avnish Jauhari, business head, lighting, Mirc Electronics Ltd. Onida LED lamps are UL approved and can work up to 380 V. These are designed, tested and validated for a lifespan of 10 years. "Our lamps are all customised and we design the light output/pattern to match various applications such as the requirements of factories, warehouses, public places of various heights and various grid sizes," adds Avnish Jauhari.

Trishul Green Lights provides die cast flood lights, panel lights, dome lights, tubelights, underwater lights, etc, with energy efficiency features in different wattages and for different applications. "The heat sinks of our products is directly exposed, hence cooling is more efficient. It is compact and has long life. Heat dissipation in some of our LED products is also being reduced," says S Nagaraj, managing director, Trishul Green Lights.
