Excessive heat generation is one of the main causes of LED failure. With the advent of Oslon Square, Osram Opto Semiconductors has successfully launched an LED that is particularly resistant to high temperatures.

To ensure that several LEDs in the luminaire maintain color consistency at higher temperatures, they are measured and sorted at 85 °C. Because this temperature is very close to the temperatures common in all lighting applications in buildings from spotlights to alternative light sources.
Osram has successfully optimized the heat dissipation of Oslon Square to withstand higher junction temperatures. In explaining the advantages of this innovative technology, Ivar Tangring, Solid State Lighting Product Development Division of OSRAM Opto Semiconductors, Germany, said: "With our new conversion technology, we are able to produce a conversion layer that is much thinner than before. This is thinner. The conversion layer helps to dissipate heat, so LEDs can withstand higher temperatures.†Even with temperatures up to 135°C in LEDs, Oslon Square can last up to 50,000 hours. 
The new Oslon Square: better heat dissipation, stable color uniformity and longer lamp life at high temperatures.
The attributes of the new Oslon Square benefit customers
For customers who need to further process LEDs into luminaires, measurement and sorting at 85 °C is of great significance. They need to obtain accurate parameter information such as luminous flux and color stability in order to best define their product attributes.
In addition, improved temperature characteristics enable higher light efficiency in applications. Mr. Tangring emphasized: “Light efficiency refers to the ratio of luminous flux to the electrical power consumed, which can help customers greatly optimize the cost performance of their luminaire solutions.†Due to the higher junction temperature that can be withstood, the required heat dissipation There are fewer pieces, so they can be smaller in size, simplifying the design of bulbs and fixtures and saving costs.
Application in interior lighting
Oslon Square is especially suitable for a wide range of applications in buildings. It has a color temperature range of 2,400K and 5,000K and produces warm white or cool white light. Its color rendering index exceeds 80, and its luminous flux is surprisingly 202 lm. In addition, product versions with different color temperature ranges and higher color rendering indexes are coming soon.
Currently, the new LED is undergoing various quality tests: the certification process for the LM-80 Life Test has been initiated and the results of the 3,000-hour test are expected to be announced by the end of this year, and the results of the 6,000-hour test will be announced in the spring of 2014.
