In an electronic apparatus comprising a circuit board supporting semiconductor components and traces or conductors for supplying electrical energy to the semiconductor components, and a connection arrangement by which the conductors are connected to a power supply cable, the circuit board being covered by an electrically insulating encapsulating layer, a molded frame part is mounted on the circuit board so as to cover the connection arrangement, the molded frame part having a circumferential edge structure which extends on one end into the encapsulating layer and at the other end projects above the encapsulating layer so as to create an interior space which, when the encapsulating layer is at least partially cured, is filled with additional encapsulating compound to form, after curing, a relatively thick protective layer over the wire or cable and conductor connecting area.

Method for making an electronic apparatus having an encapsulating layer within and outside of a molded frame overlying a connection arrangement on a circuit board

In a lighting apparatus, comprising a heatsink having at one side thereof a recess with at least one groove extending over the length of the heatsink, a plurality of lighting units are arranged in the groove or grooves oriented toward the opening of the recess for the emission of light therefrom and the frame is provided at the side opposite the opening with heatsink ribs, the lighting units in the groove or grooves being encapsulated by an encapsulating material added into the groove or grooves and being cured therein so as to be in direct contact with the groove walls and enclosing the lighting units at least up to the light emitting lenses thereof.

An LED module or assembly is disclosed, the assembly having at least one LED component mounted on a support or circuit board and an optical element which encloses the at least one LED component and defines an interior space in which the at least one LED component is housed. A vent device is defined within the optical element for permitting gases generated from operation of the at least one LED component to be vented to atmosphere. The vent device prevents outside moisture from entering the interior space, but permits the gases to pass out to atmosphere for minimizing the likelihood of fogging of the optical elements in the interior space of the assembly.

In a light emitting diode arrangement for lighting purposes, comprising a circuit board with at least one light generating semiconductor element disposed on the circuit board and conductors extending on the circuit board to the semiconductor element and being electrically connected to terminals of the semiconductor element, a light transmissive element is disposed on the circuit board and covers the semiconductor element and a flame resistant cover element is disposed below the light transmissive element and on top of the terminals to cover the terminals to provide for electrical and flame insulation thereof.

Light emitting diode arrangement for high safety requirements

A light source element is employed back-lighting of liquid crystal displays and that comprises an obliquely placed light exit face and/or light entry face. At its surfaces, the light waveguide is surrounded by reflectors into which suitable aperture regions are potentially formed. A plurality of light sources and/or a more direct view is provided and, thus, a corresponding increase of the luminance results. A method is also provided for the manufacture of a light source element with an integrated reflector.

The invention relates to a lighting device, comprising a light guide (), a light source (), which couples the light that is emitted into the light guide, and a support () in the form of a shell, consisting of several interconnected sub-shells which enclose the light guide, at least in the area in which the light should be deviated. The invention also relates to a method for producing a lighting device.

Illumination arrangement

A passive radiation optical system includes a one-piece module having a plurality of individual optical components wherein the one-piece module is radiation-permeable or reflective. The optical components are connected to one another via predetermined breaking points for forming a radiation optical system module. In addition, the one-piece module can be separated to form optical components that include one or more individual optical components. The one-piece module is particularly for use with light emitting diodes. The passive radiation optical system module is suitable for mass production, and because of its modular principle, it enables flexible adaptation to the shape and size of the desired lighting device, such as lighted advertising or safety lighting.

An LED module includes a substrate having good thermal conductivity and one or more radiation-emitting semiconductor components that fixed on the top side of the substrate. The underside of the substrate is fixed on a carrier body having a high thermal capacity, in which the component fixing between the semiconductor components and the substrate and the substrate fixing between the substrate and the carrier body are embodied with good thermal conductivity. Furthermore, the invention relates to a method for producing the LED module, in which metal areas that are suitable as an etching mask improve the impressing of the current required during the anodic bonding, and at the same time, are used as contact areas for contact-connecting the radiation-emitting semiconductor components. The LED module has the advantage that the semiconductor components can be subjected to higher energization as a result of the high thermal capacity of the carrier body.

LED module and methods for producing and using the module

The invention describes a flexible multiple LED module having a plurality of rigid printed circuit boards, which are each connected at one of their main surfaces to a flexible printed circuit board with a spacing between one another, and a plurality of LEDs, which are mounted in the region of the rigid printed circuit boards on the flexible printed circuit board. The multiple LED module is suitable particularly for installation in luminaire housings, in particular for motor vehicles.
