Cree issued a press release yesterday saying that the company has signed a cross-licensing agreement with Ledvance, under which Cree will continue to collect royalties from Ledvance and obtain a royalty-free license for the Ledvance patent portfolio. In exchange, Ledvance will also receive Cree's license for a patent portfolio of LED bulbs and LED luminaires. Licensed patents cover all aspects of LED lighting, including optics, thermal management, LED power and control, LED light efficiency, and light color and uniformity. However, certain Cree patents covering Cree Network Lighting Technology (SmartCast) and Color Mixing Technology (TrueWhite) are not included in this license.
"With the development of intellectual property over the past 29 years, Cree has a strong technology portfolio that is the basis for the design and manufacture of high-performance LED bulbs and LED luminaires," said Brad Kohn, vice president of law and general counseling at Cree. Ledvance's latest licensing agreement is another example of the value of Cree's R&D investment and the breadth and strength of Cree's lighting technology. â€
Prism, a transparent object surrounded by two intersecting planes that are not parallel to each other, used for splitting or dispersing light beams. Prism is a polyhedron made of transparent materials (such as glass, crystal, etc.). It is widely used in optical instruments. Prisms can be divided into several types according to their properties and applications. For example, in spectral instruments, the "dispersion prism" that decomposes the composite light into spectrum is more commonly used as equilateral prism; In periscope, binocular telescope and other instruments, changing the direction of light to adjust its imaging position is called "total reflection prism", which generally adopts right angle prism.
