Future high-efficiency lighting for cold storage walk-insPosted in Green by mmathews on 06/23 at 10:22 PM Luxim introduced a high-efficiency bulb design that could rewrite the formula for cold storage lighting in power consumption, wattage, color, and heat output. About the size of a tiny Christmas string light, Luxim’s bulb transfers most of the energy input to light instead of heat. The bulb itself is filled with argon gas and does not use embedded electrodes, an electric field is driven into the bulb through what is called a “puck”. The electric field vaporizes the argon into a plasma that outputs 6000K daylight-spectrum light at a very high lumen per watt. Typical lumens per watt ratings are: The full daylight color spectrum is an advantage in determining the condition of perishable or frozen food items, which can be difficult to see under some lighting. The entire unit is RoHS compliant, meaning there is no lead or other environmentally harmful substances in the bulb. Argon gas is inert, unlike the substances used in many lighting systems. With an operating temperature range of -40C to +40C, these bulbs could easily handle the environment of a cold storage warehouse or walk-in cooler or freezer. Even better, there’s no lifetime derating for bulb orientation or short cycle times. The only drawback is the 30-second warm-up and two-minute restrike. Check the ZDNet video (only 1:30) where Luxim CEO Tony McGettigan explains the properties of the bulb and the technology used. Make a comment | (0) Comments |
