  • Optoelectronic component and method for producing it
    Publication number: 20040089898
    Abstract: An optoelectronic component having a basic housing or frame (12) and at least one semiconductor chip (20), specifically a radiation-emitting or -receiving semiconductor chip, in a cavity (18) of the basic housing. In order to increase the efficiency of the optoelectronic component (10), reflectors are provided in the cavity in the region around the semiconductor chip. These reflectors are formed by virtue of the fact that a filling compound (28) filled at least partly into the cavity (18) is provided, the material and the quantity of the filling compound (28) being chosen in such a way that the filling compound, on account of the adhesion force between the filling compound and the basic housing, assumes a form which widens essentially conically from bottom to top in the cavity, and the conical inner areas (30) of the filling compound serve as reflector.

  • Method for producing a shaped piece suitable for optical purposes
    Patent number: 6162853
    Abstract: Described is a process for preparing a molding suitable for optical purposes, which process comprises the conjoint free-radical polymerization of a precondensate (A) which is derived from at least one hydrolytically condensable silane (a) having at least one free-radically polymerizable group X, and of a monomer (B) having at least two free-radically polymerizable groups Y, the numerical ratio of groups X to groups Y being not greater than 5:1. The moldings obtainable by this process are characterized by high transparency and homogeneity, freedom from stress, scratch and abrasion resistance, high mechanical strength, etc.
