A bidirectional light sheet including at least first and second arrays of bare LED chips having top and bottom electrodes, where the arrays of LEDs are sandwiched between at least two transparent substrates having conductors bonded to the electrodes without wires, forming light sheets to emit light from opposite surfaces of the light sheet to create a bidirectional light sheet. The light sheet may be suspended from a ceiling to be non-parallel to the ceiling A reflector or a plurality of lenses may be included in the light sheet to emit light at any peak intensity angle to achieve a predetermined light emission pattern.

An LED filament includes LED chips, two conductive electrodes, light conversion coating, and attaching structure. The LED chips are electrically connected with one another. Each of the two conductive electrodes is electrically connected to a corresponding LED chip of the LED chips. The light conversion coating is coated on two sides of the LED chips and the two conductive electrodes. A portion of each of the two conductive electrodes is exposed from the light conversion coating. The light conversion coating includes a top layer and a base layer. The base layer coats on one side of the LED chips, and the top layer coats on another sides of the LED chips. The attaching structure is between the top layer and the base layer, between the base layer and the conductive electrodes, or between the top layer and the conductive electrodes.

An illumination device includes a supporting base, and a light-emitting element inserted in the supporting base. The light-emitting element includes a substrate having a supporting surface and a side surface, a light-emitting chip disposed on the supporting surface, and a first wavelength conversion layer covering the light-emitting chip and only a portion of the supporting surface without covering the side surface.

An illuminated multifunctional lamp shade assembly including a frame, a finial, at least one light, a timer and a battery is provided. The assembly can be used for lighting in emergency circumstances, or in addition to, or instead of, standard lighting under non-emergency circumstances. The assembly can be portable such that it can be used in place on a lamp or removed and be used as an independent portable light source for a variety of applications.

An array of LEDs is supported by a support mechanism that both supports conductors leading to the LEDs and sinks heat from the LEDs. The support mechanism may be a transparent heat-conducting sheet or an array of cantilevered arms at different angles that support the LEDs and sink heat. This reduces the blockage of light. The LEDs are positioned generally in the focal plane of an array of concave mirrors that collimate the light. The LEDs and array of mirrors are translatable with respect to one another to steer the aggregate light beam to customize the emission. In another embodiment, multiple LEDs are positioned over each mirror in the mirror array, and the combination of LEDs illuminated over each mirror is used to steer the aggregate light beam from the luminaire.

A lamp or display is comprised of at least one light panel (10) on a carrier plate (13) comprising at least one light panel (10) in the form of an OLED illuminant, lying on or against an at least partially light-permeable carrier plate (13) of the lamp in a planar manner. A liquid or viscous medium (11) is arranged between the adjacent surfaces of the light panel (10) and of the light-permeable carrier plate (13), and the connection between the light panel (10) and the carrier plate is an adhesive connection, which can be easily undone without destroying or adversely affecting the carrier plate (13).

An illumination device includes a supporting base, and a light-emitting element inserted in the supporting base. The light-emitting element includes a substrate having a supporting surface and a side surface, a light-emitting chip disposed on the supporting surface, and a first wavelength conversion layer covering the light-emitting chip and only a portion of the supporting surface without covering the side surface.

An illumination device including an upper casing, a transparent bottom casing, a light source module and a reflection layer is provided. The upper casing has a lower surface. The transparent bottom casing has an upper surface. The light source module is disposed on the lower surface of the upper casing. The reflection layer is extended between the upper surface of the transparent bottom casing and the lower surface of the upper casing for reflecting the light emitted by the light source module.

An illuminated multifunctional lamp shade assembly including a frame, a finial, at least one light, a timer and a battery is provided. The assembly can be used for lighting in emergency circumstances, or in addition to, or instead of, standard lighting under non-emergency circumstances.

Apparatus, system, and method embodiments are disclosed for illuminating clothing, fashion accessories, and other items using diffusion and reflection of light from a light source. A fashion accessory can include a diffusion layer to provide a unique visual appearance from the light source based on the diffusion layer's manipulation of photon wavelength. The diffusion layer can reside under an exterior shell of the fashion accessory and diffuse light from the light source, providing a unique design aspect to the fashion accessory. The fashion accessory can further include a light refraction chamber to direct light in a visually appealing way, providing variations in quality and texture of the light that an observer sees. Additional layers of material over the exterior shell can provide additional variations in quality and texture of the observed light.
