The LED doesn’t burn out in the conventional sense. To have a way of describing what happens, product life is measured as lumen depreciation. The life span of an LED is much longer than that of incandescent, fluorescent or HID lamps. Fluorescent or HID light sources also show a reduction in light output before they [...]
Probably not. It is not really practical since the assembly process for the individual diode requires precision control of temperature and excellent process cleanliness. A more important question is to consider the arrangement of LEDs within the fixture. Just like the old Christmas tree lights where one bad bulb made and all of the lights [...]
Most of the fixtures now being offered for sale must be removed from service and repaired by the manufacturer, or (more than likely) discarded. ALLED has designed their fixtures with the intent of preserving the value of the customer’s investment over the very long term. ALLED’s patented Rapid Change Capability offers unparalleled ability for the [...]
With a correctly designed fixture: LEDs yield very high energy-efficiency, ruggedness, and superior life, as compared to other light sources; Required maintenance on such correctly designed fixtures is greatly reduced; Energy savings and maintenance savings combine to yield an overall reduction in cost of ownership, as compared to other light sources; and LED lights are [...]
One of the design criteria for a conventional housing is to prevent injury to the user or to prevent starting a fire. Traditionally, only enough cooling is provided to keep the body of the housing at a user-safe level. Therefore, high internal temperatures are common with such fixtures. To operate at a temperature that supports [...]
LEDs are used for general illumination, aesthetic, effect, or specialty lighting applications, including architectural highlighting. Traffic lights and exit signs also now use red, yellow, green or blue LEDs. ALLED has focused its LED lighting technology into commercial applications where long lasting, efficient, and generally maintenance free lighting is needed to illuminate streets, highways, parking [...]
LED is short for Light-Emitting Diode. An LED is a semiconductor diode that emits light when current is passed through it. LEDs have been used since the 1970’s as indicator lights on electronic products. Recently the efficiency, reliability, and light output of LEDs have improved to the point where they are not only useful for [...]
