For LED lamp, light engine and luminaire manufacturers to receive an Energy Star certificate for their products, the US Environmental Protection Agency (EPA) requires that the LEDs used in these products must comply with the LM-80 (Lumen Maintenance) test requirements. LM-80 test reports provide evidence that the LED component can be assessed and compared across all LED manufacturers. OSRAM Opto Semiconductors is one of the first to have successfully met the criteria of the LM-80 test requirements with two very different product families – OSLON SSL and Golden DRAGON Plus.
Two different high-power LEDs from OSRAM Opto Semiconductors were tested – the ceramic OSLON SSL LED and the Golden DRAGON Plus premold LED. Inaugurated by the Illuminating Engineering Society (IESNA), the LM-80 test offers luminaire manufacturers a means of comparing the performance of LEDs from different suppliers based on reliable and comparable data. Successful completion of the LM-80 test is an essential step toward receiving an Energy Star certificate from the EPA.
The aim of the LM-80 test is to demonstrate, in an abbreviated test of 6,000 hours (approximately nine months), a consistent industry method of measuring lumen maintenance of SSL sources, such as LED packages, arrays and modules. The LM-80 specifies that LEDs are tested at three different temperatures to assure performance in various conditions. In addition to the two predefined temperatures of 55°C and 85°C, OSRAM has used a third temperature of 105°C to simulate the requirements of highly demanding applications.
“Successful completion of the LM-80 test for two of our very different LED product families is a significant achievement, but it’s only the start. Other products are already in the test phase, so in the near future all our high-power LEDs for General Lighting will comply with LM-80 testing requirements. Luminaire manufacturers will then have an important platform for Energy Star certification by the EPA”, said Artur Groesbrink, who is responsible for standardization at OSRAM Opto Semiconductors. “The Energy Star certification is essential if companies want to market their products successful in the United States.”
