Light-emitting diodes (LEDs) have become a staple in modern lighting and signaling systems, effectively replacing traditional light bulbs. Their advantages are numerous: they consume significantly less energy, are highly durable, and are available in a vast range of sizes and configurations. This versatility allows LEDs to be incorporated into solutions that are not only energy-efficient but also come in a variety of unconventional shapes and sizes, particularly miniaturized designs.
LEDs can be integrated into traditional control panels, such as those found in control cabinets, or seamlessly embedded into consumer devices to serve as indicators, signaling whether a certain function is active. An interesting feature in compact designs is the use of special optical fibers, which can transmit light from an LED mounted on a printed circuit board (PCB) to a remote signal panel, allowing for space-saving solutions.
Optosupply has introduced an innovative solution with its miniature LEDs, measuring just 1.0×0.4×0.4 mm, mounted at the end of a slender wire with a diameter of 0.25 mm and a length of approximately 300 mm. The wire is equipped with a goldpin connector (with a pin pitch of 2.54 mm), offering numerous new possibilities and making the modular design of devices more accessible. These compact modules are ideal for use in small devices where space constraints would typically make optical fibers impractical. The flexibility of having the LED mounted on a wire also allows for use as an indicator on mobile components. Potential applications range from model making—such as airplane lights, railway signals, or street lamps—to toys, as well as backlighting buttons, knobs, or controls in consumer, professional, or industrial devices.
The compact size, ease of use, and availability of a wide range of colors make these miniature LEDs an excellent choice for bringing to life ideas that may have been challenging or impossible to achieve with other lighting components.
