Abstract: Crimping of an LED leadframe to a subassembly may stress the leadframe. Flat leadframes cannot accommodate these stresses. Strain relief sections are added to the leadframe to accommodate crimping or other stresses on the leadframe. Strain relief sections are created in the leadframe in the form of openings, notches or bulges. The strain relief sections may be symmetric or asymmetric.

Abstract: Crimping of an LED leadframe to a subassembly may stress the leadframe. Flat leadframes cannot accommodate these stresses. Strain relief sections are added to the flat leadframe to accommodate crimping or other stresses on the leadframe. Strain relief sections are created in the leadframe in the form or openings, notches or bulges. The strain relief sections may be symetric or asymmetric.

Abstract: A leadframe (610) is formed that simplifies the packaging of light emitting elements and/or eliminates the need for stress-inducing folding after encapsulation. In particular, the folding of the contact tabs (505, 506) for surface mounting is performed prior to the mounting and encapsulation of the light emitting elements on the leadframe. In an example embodiment, the leadframe may be formed so that an array, or matrix, of light emitting elements may be packaged during a single packaging process.

Abstract: Conventional techniques are used to control the flux of an LED element, by modifying a surface of a light emitting element. One type of modification is roughening the surface, to enhance the light extraction efficiency. The degree of modification of the surface is controlled by controlling one or more of the parameters associated with the modification process. A given LED technology will have some minimum flux without modification and some maximum flux with optimal modification. By characterizing the relationship between the parameters of the modifying process and the resultant flux, the parameters of the modification process can be controlled to achieve a desired flux between the minimum and maximum flux achievable by the given LED technology.
