Abstract:
The invention relates to a headlight comprising a plurality of headlight elements which respectively comprise at least one semiconductor chip emitting electromagnetic radiation; a primary lens element reducing the divergence of an incident light passing through a light input; at least one headlight element output which is used to radiate part of the light of a headlight from the headlight element. At least one of the headlight element outputs is arranged in at least two groups such that the arrangement of at least one group and/or at least the overall arrangement of the headlight element outputs corresponds essentially to a desired radiation characteristic of the headlight, such that in particular a form arises substantially corresponding to the cross-sectional shape of a desired headlight beam, whereby the semiconductor chips belonging to the headlight element outputs of one group can be respectively operated independently from the other semiconductor chips. The invention relates to a headlight element which is suitable for use with said type of headlight.
Abstract:
The invention relates to a conductor frame (1) for at least one electronic component, comprising at least two electric connection parts (2) with respectively at least one electric connection strip (3) and at least one retaining strip (4). The connection frame (1) is characterized in that an indentation is provided between the at least one retaining strip (4) and connection part (2), creating a parallel offset between the retaining strip (4) and adjacent area of the connection part (2), and in that another parallel offset is created between the connection part (2) and electrical connection strip (3) such that the retaining strip (4) and electric connection strip (3) are located on a common plane. The retaining strip (4) can be removed easily through the indentation (8) without having to create a disadvantageous stamping gap between the connection part (2) and the retaining strip (4).
Abstract:
The invention relates to a surface-mountable light-emitting diode, comprising a chip housing, which has a lead frame (16) and a semiconductor chip (22). This semiconductor chip is situated on the lead frame (16) while in electrical contact therewith and contains an active radiation-emitting region. According to the invention, the lead frame (16) is formed by a flexible layer (12, 14) consisting of multiple layers.
Abstract:
The invention relates to an optoelectronic component comprising a semiconductor chip (1), which is mounted on a flexible chip support (6). Strip conductors (3, 5) for electrically connecting the semiconductor chip (1) are configured on a first primary surface of said support and the latter also accommodates a housing frame (7), which is filled with a radiation-permeable medium, in particular a filler compound. The invention also relates to a display device, an illumination or backlighting device and to a method for producing components according to the invention.
Abstract:
The invention relates to a high-radiance LED chip (1) comprising a radiation-emitting active region (32) and a window layer (2). In order to increase the radiant yield, the cross-sectional surface of the radiation-emitting active region (32) is smaller than the cross-sectional surface of the window layer (2), which is made available for disengaging the light. The invention also relates to a method for producing a lens structure on the surface of a light emitting component.
Abstract:
The invention relates to two methods for producing semiconductor elements, wherein a luminescence converter element is directly arranged on a semiconductor body (1). According to the first method, a suspension (4) containing a bonding agent and at least one luminous substance (5) is applied to the semiconductor body (1) in the form of a coating. In the next step, the solvent is removed, whereupon only the luminous substance (5) and the bonding agent remain on the semiconductor body. According to the second method, the semiconductor body (1) is provided with a bonding coating (6) on which the luminous substance is directly deposited.
