Abstract

An omnidirectional light emitting device is provided. An example device includes a flexible substrate (102) having a substrate length, a first substrate surface (1022), and a second substrate surface (1024). The flexible substrate is configured to be flexibly wrenched about a longitudinal axis that is parallel to the substrate length. The example device further includes a plurality of LED packages (104) disposed on the first substrate surface (1022). Each LED package of the plurality of LED packages (104) is configured to emit light outward from the flexible substrate (102).

IPC Classes  ?

• F21K 9/232 - Retrofit light sources for lighting devices with a single fitting for each light source, e.g. for substitution of incandescent lamps with bayonet or threaded fittings specially adapted for generating an essentially omnidirectional light distribution, e.g. with a glass bulb
• F21S 4/24 - Lighting devices or systems using a string or strip of light sources with light sources held by or within elongate supports flexible or deformable, e.g. into a curved shape of ribbon or tape form, e.g. LED tapes
• H01L 25/075 - Assemblies consisting of a plurality of individual semiconductor or other solid state devices all the devices being of a type provided for in the same subgroup of groups , or in a single subclass of , , e.g. assemblies of rectifier diodes the devices not having separate containers the devices being of a type provided for in group
• H05K 1/18 - Printed circuits structurally associated with non-printed electric components
• F21Y 115/10 - Light-emitting diodes [LED]
• F21Y 103/10 - Elongate light sources, e.g. fluorescent tubes comprising a linear array of point-like light-generating elements
• F21Y 107/70 - Light sources with three-dimensionally disposed light-generating elements on flexible or deformable supports or substrates, e.g. for changing the light source into a desired form
