A plurality of types of lens bodies 50 that emit the light originated from the LED 42 in different light distribution patterns are previously prepared, and an appropriate one is selected from among them.

A display article includes a film formed from a stretchable plastic and including a first plurality of micro-light emitting diodes and a second plurality of micro-light emitting diodes disposed adjacent to the first plurality and embedded in the plastic. The article includes a substrate having a first portion and a second portion, and a tear seam disposed between the first and second portions. The film is attached to the substrate such that the tear seam is located between the first and second pluralities. A component includes the display article and an airbag disposed adjacent the substrate and configured for transitioning between a stowed position in which the airbag does not extend through the substrate, and a deployed position in which the airbag extends through the substrate and the film. The first and second portions are separated at the tear seam when the airbag is disposed in the deployed position.

A light-emitting diode (LED) lamp for a vehicle and a method of manufacturing the same use MID and magnetic induction technologies. The LED lamp includes a LED module, a housing accommodating the LED module, and a molded interconnect device (MID) electrode formed on a surface of the housing.

The present disclosure describes example magnetic LED lighting systems. A lighting apparatus in accordance with the present disclosure may include LEDs connected in series with a resistor. The LEDs are each coupled, directly or via thermal vias through a mounting element, to one or more magnets. The magnets may serve dual purposes: as a heat sink to dissipate heat and enable LEDs to be used, and as a mounting device to mount the lighting apparatus to a desirable location, such as on an automobile or an industrial machine. The dual-purpose magnets may eliminate the need for an additional heat sink element, thereby reducing weight and/or size of the lighting apparatus.
