Flexible LED Device with Whole Body Illumination

Abstract

A flexible LED lighting device is disclosed that includes a flexible LED light bar surrounded by a flexible conduit. The flexible LED light bar fits within a inner channel of the flexible conduit in an elongated direction and includes sets of LED arrays on opposed sides of a flexible elongate circuit board formed from a continuous wire band and circuit board segments. Preferably, the flexible conduit includes a tubular outer sleeve that surrounds a tubular inner sleeve and the tubular inner sleeve and LED light bar are cable of being displaced in a radial directions relative to the outer sleeve or in directions that are substantially orthogonal to the elongated direction. The flexible conduit is translucent and / or patterned to diffuse or scatter light emitted from the LED light bar to provide full-body illumination.

AI Technical Summary

Benefits of technology

The solution provides enhanced flexibility and full-body illumination, reducing the risk of damage from torsional stresses and enabling longer, more flexible LED light fixtures with improved light distribution and ease of production.

Problems solved by technology

In some of these LED strip lights, the flexible circuit boards are only flexible in two directions, much like a flattened strip of metal, and are subject to damage when they are bent or twisted in other directions as a result of torsional stresses along the thickness directions.

While such wire mounted LED strip lights do allow for more flexibility, making such LED strip lights with larger LEDs is prohibitive because the wires do not provide a stable support for the larger LEDs.

Further, with these wire mounted LED strip lights, each LED must be individually soldered or connected to the wires, thereby making a wire mounted LED strip light labor intensive to produce.
