Innovations in Easy Assembly of LED Lighting Components

An illumination apparatus designed for lighting applications with directional output using LEDs and optical elements. The apparatus features an array of directional catadioptric optical elements aligned with an array of LEDs. These optical elements include electrodes that provide electrical connections to the LEDs, allowing the LEDs to be packaged separately from the optics. The optical element array can be assembled with the LED array to create the complete illumination apparatus.

A light-emitting device designed to prevent cracks in solder joints between substrates in LED displays while reducing the number of connectors. The device features two substrates: one flexible and one rigid. At one end, the flexible substrate overlaps the rigid substrate without covering the wiring patterns. An electrically conductive joining member spans across the wiring patterns to connect the substrates. This design enables flexible arrangement and prevents solder joint cracks.

A light-emitting device with a cost-effective substrate joining structure that allows for flexible substrate arrangement. It consists of a first flexible substrate with mounted light-emitting elements and a second substrate. The first substrate overlaps part of the second substrate without covering its wiring. An electrically conductive joining member bridges the wiring patterns of both substrates. This design eliminates the need for connectors or adhesives, reducing manufacturing complexity and costs.

An approach for creating customized and efficient LED lighting devices involves assembling a monolithic array of LEDs and then selectively modifying it to achieve desired configurations. The process starts with a monolithic array of LEDs, from which specific LEDs are selectively removed and transferred to form a customized array with specific positions and spacings. This non-monolithic array is then aligned with an array of optical elements to create the final illumination apparatus. Techniques such as light or laser-based separation are used to remove and position LEDs precisely, allowing for optimization of the LED arrangement to match the optical elements. This method enhances efficiency by avoiding the need to manufacture LEDs in the final configuration from the outset.

An LED-based illumination apparatus designed for efficient, directionally controlled lighting features reduced manufacturing complexity. It comprises an array of custom optical elements, such as lenses, aligned with a separate array of LEDs. The optical elements focus and direct the light emitted by the LEDs. The optical array includes electrodes for electrical connections to the LEDs. LEDs are initially formed in a monolithic array but are selectively removed and transferred onto a substrate to create a customized LED array with specific compositions and spacings. This custom array is then assembled with the optical array, allowing for precise configuration and alignment. Techniques like selective removal from the monolithic array facilitate this customization, while the optical array ensures proper electrical contact with the LEDs.

Low-cost, small-sized holder for an LED that can easily contact and mount a variety of different CoB-LEDs having contact pads in different locations. The holder includes a base, a contact, and a T-shaped contact section. The contact is connected to electrical wiring and has a receiving section to connect to a cable. The base holds the contact and exposes the T-shaped contact section in a receptacle that receives the LED board. This allows the T-shaped contact to electrically contact a pad on the LED board.

An illumination apparatus that provides a highly efficient, compact, and customizable lighting solution. The apparatus involves an array of separately formed optical elements and a separately formed array of light-emitting elements. The optical element array contains reflective or refractive elements that direct light emitted by the light-emitting elements. The optical element array also has electrodes to electrically connect to the light-emitting elements. The optical and light-emitting element arrays are assembled with alignment so each light-emitting element is positioned at an input surface of an optical element. This enables the separately formed light-emitting array to be customized and optimized independently from the optical elements.

Modular lamp design with easily replaceable planar semiconductor lighting elements that can be mounted in sockets. The lamp consists of an illuminant with a planar LED lighting surface that can be inserted into a socket. The socket provides the electrical and mechanical connection to power the illuminant. Multiple illuminants can be inserted into adjacent sockets to create a larger common illumination surface. The sockets can have connections on multiple sides for flexible wiring and shorted supply connections to simplify electrical connections.

A light-emitting device with a simplified, cost-effective structure using overlapping substrates and a joining member. The device has two overlapping substrates with wiring patterns and light-emitting elements. The substrates are partially overlapped with the first substrate overlapping a portion of the second substrate. An electrically conductive joining member is positioned across the wiring patterns. This configuration allows the substrates to be connected with just one joining member instead of multiple connectors.

A lighting module for vehicle headlights and other lighting applications that can simplify production and reduce costs compared to traditional connectors. The module has an electrical connector for connecting to vehicle wiring that is mounted directly to a heat sink using an electrical interconnection device such as a printed circuit board. This eliminates the need for a two-part connector with the second part joining after the heat sink mounting. The module design also includes a cavity on the heat sink to prevent electrical contact between the connector contacts and the sink.

LED light fixture with detachable modules that makes it easy to replace them when needed or add/remove modules to adjust brightness. The fixture has a frame with a power connector. The LED module has a connector that slides into the frame and connects to the power connector. This allows the module to be quickly attached/detached for maintenance or to customize brightness by adding/removing modules.

A connector for holding and electrically connecting an LED module substrate without screws. It uses a two-piece cover system. Closing the upper cover piece over the lower piece clamps the LED module in between. The upper cover has spring-loaded contact pads that make electrical connection with the module's contact pads. The clamping action of closing the covers holds the module securely in place and establishes electrical contact. This eliminates the need for screws and provides reliable electrical connection to the module.

LED-based lamp assembly for retrofitting light fixtures without requiring rewiring or modifications. The lamp assembly has a rotating driver assembly that screws into the existing socket and makes electrical contact. A lamp housing with LEDs is connected to the driver. The driver and housing rotate independently to adjust the light direction. Heat sinks and fans cool the LEDs. The rotatable driver and housing allow aiming the LEDs without modifying fixtures.

Flexible circuit board assembly for an LED lamp to improve heat dissipation, maintain shape, and enable efficient production. The assembly uses a strip-shaped resin layer as a substrate. On the upper surface, a signal line layer made of copper or aluminum is patterned for electrical connections. On the lower surface, a thicker heat dissipation layer made of the same metal is added to dissipate LED heat.

A modular organic light emitting diode (OLED) light source and fixture that allows easy installation and prevents OLED unit from falling out. The light source unit attaches to the socket using spring biased engagement claws. The socket has a holding mechanism that keeps the claws disengaged when the OLED unit is not present. When the OLED unit is inserted, the holding mechanism releases the claws to engage and hold the unit in place.
