Abstract

A housing for an optoelectronic component comprises a housing body and first and second electrical terminal strips. The first and second terminal strips extend in part inside the housing body and are guided out of the housing body at a first side face. Outside the housing body the two terminal strips are bent in such a way that they comprise a first portion extending at an angle to the first side face, and a second portion (11d, 12d) extending along and spaced from the first side face. A method for producing such a housing is also described.

Claims

1. A housing for an optoelectronic component, the housing comprising:

a housing body comprising a first side face arranged at an angle to a front and a back of the housing body;

first and second electrical terminal strips for supplying an optoelectronic semiconductor chip with electricity, the first and second electrical terminal strips each having a first part inside the housing body and a second part guided out of the housing body at the first side face, the second parts of the first and second electrical terminal strips being bent outside the housing body to form a first portion extending at an angle to the first side face, and a second portion extending along the first side face, spaced at a spacing from the first side face; and

supporting elements connected to the housing body, wherein the supporting elements have an elongate shape, extend from the front to the back of the housing body, project out of a plane of the first side face, and form a tunnel-like cavity,

wherein the first and second electrical terminal strips are within the tunnel-like cavity.

2. The housing according to claim 1, wherein the spacing between the first side face and the second portions of the terminal strips is between 0.4 mm and 0.6 mm in size.

3. The housing according to claim 1, wherein the first and second portions form an angle which is greater than 90°

.

4. The housing according to claim 1, wherein the terminal strips are at least 0.2 mm thick.

5. The housing according to claim 1, wherein the supporting elements have a height corresponding at least to the spacing of the second portions from the first side face plus the thickness of the terminal strips.

6. The housing according to claim 1, wherein the housing body further comprises a second, square-shaped side face arranged parallel to the first side face.

7. The housing according to claim 1, wherein the housing body further comprises a third side wall and a fourth side wall each arranged at an angle to the first side face, the third and fourth side walls each defining respective openings.

8. The housing according to claim 7, wherein the respective openings lead into a rear cavity in the housing body.

9. The housing according to claim 1, wherein the first and second electrical terminal strips are separated from one another by a gap which is smaller than the width of the supporting elements.

10. The housing according to claim 1, wherein the housing body comprises a recess at the front to accommodate the optoelectronic semiconductor chip.

11. The housing according to claim 10, wherein an extension of the first electrical terminal strip extending inside the housing body projects into the recess.

12. A side emitting component having a housing according to claim 1, and a radiation emitting semiconductor chip arranged inside the housing body, wherein the component is configured to be arranged on a terminal carrier so that the second portions of the terminal strips extend along the terminal carrier for connection to the terminal carrier by an electrically conductive joining agent.

13. A method of producing a housing according claim 1, comprising:

introducing a terminal frame with a first electrical terminal strip and a second electrical terminal strip, the first and second electrical terminal strips being flat, into a shaping device, wherein a first and a second portion of the first and second electrical terminal strips project out of the device;

filling the device with a housing body compound for forming the housing body, to at least partially embed the first and second electrical terminal strips in the housing body compound;

bending the first and second electrical terminal strips before or after completion of the housing body, such that the first portions of the first and second electrical terminal strips extend at an angle to the second portion; and

connecting first and second supporting elements to the housing body, from the front to the back of the housing body, wherein the first and second supporting elements project out of the plane of the first side face, have an elongate shape, and form a tunnel-like cavity receiving the first and second electrical terminal strips.

14. The method according to claim 13, comprising injection molding the housing body from thermoplastic material.
