Surface-mounted optoelectronic device
First Claim
1. An optoelectronic device for surface mounting comprising an insulating substrate having an upper and a lower surface, at least one optoelectronic element mounted at said upper surface, contact members on said lower surface, conductive strips disposed on the upper surface and in electrical contact with said contact members on the lower surface, a first of said conductive strips being in electrical contact with the lower surface of the optoelectronic element and at least a second of said conductive strips being connected to the upper surface of the optoelectronic element, an annular spacer enclosing but spaced apart from said optoelectronic element and fixed to the upper surface of the insulating substrate so that its axis is aligned with the optical axis of the optoelectronic element, said spacer having a height exceeding the thickness of the optoelectronic element, and a spherical lens of a transparent material having a diameter exceeding the inner diameter of the annular spacer, glued to the latter and spaced apart from the upper surface of the optoelectronic element by a distance such that the plane of light emission of the optoelectronic element is situated at a distance d from the spherical lens which is smaller than or equal to its extension, which is the distance between the focus F and the edge of the lens.

Abstract
The invention relates to an optoelectronic device for surface mounting of the type comprising an insulating substrate, whose upper surface receives at least one optoelectronic element electrically connected to contacts of the lower surface of the substrate through conductive strips. An annular spacer is fixed to the upper surface of the substrate. A spherical lens is glued on the annular spacer and the plane of light emission is situated at a distance from the spherical lens which is smaller than its extension.
