Abstract
In order to apply an optical element such as a lens, for example, to an optoelectronic component, the surface (3B), averted from the transmitter or receiver (2), of the filling material (3) is designed directly with a lens profile (7). This is done by filling a defined quantity of the transparent filling material (3) into the recess (1A) of the carrier body (1) for the purpose of embedding the transmitter or receiver (2), and by subsequently impressing a lens profile (7) onto the surface (3B), averted from the transmitter or receiver, of the transparent filling material (3) by means of a punch (8), before the transparent filling material with the lens profile (7) thus impressed is completely cured.
Claims13
An optoelectronic component, comprising:
- a carrier body with a recess;
- an optoelectronic transmitter or receiver arranged in the recess on the carrier body;
- and
- a filling which is made from a transparent material and embeds the optoelectronic transmitter or receiver in the recess of the carrier body,
- wherein a surface, averted from the transmitter or receiver, of the filling is designed with a lens profile, and
- wherein said surface, averted from the transmitter or receiver, of the filling does not protrude substantially from a surface, averted from the transmitter or receiver, of the carrier body.
A method for producing an optoelectronic component having a carrier body with a recess and an optoelectronic transmitter or receiver arranged in the recess on the carrier body, the method comprising the steps of:
- forming the recess in the carrier body;
- mounting the transmitter or receiver in the recess thus formed;
- filling a defined quantity of a transparent filling material into the recess for the purpose of embedding the transmitter or receiver;
- impressing a lens profile on a surface, averted from the transmitter or receiver, of the transparent filling material;
- and
- curing the transparent filling material having the surface having the lens profile.
