Provided are foldable light softboxes for users to conveniently carry around. The softbox comprises a body portion, a set of flexible and foldable frames, means for switching the softbox between an unfolded state and a collapsed state, and means for fitting the softbox over light sources of different sizes. The body portion of the softbox comprises a front panel, a back panel and a strip of material that circumferentially attached to the front panel to the back panel. The flexible and foldable frames are attached along the circumferences of the front and back panels. The softbox can be folded to fit in a circular container, for example, a bag.

A lighting device assembly includes a light source attached to a heat sink member, a first optic device and a mounting housing configured to be secured in or to a ceiling, wall or other object, and to hold the heat sink member. A second optic device including a second optic member is configured to receive light emitted in a first direction from the light emitting surface of the first optic device and to emit light in a second direction that is transverse to the first direction. A connection mechanism selectively connects the second optic device to the mounting housing, for selective disconnection from the mounting housing.

A lamp includes a base, a light emitting module mounted to the base, a lens member and a decorating unit. The lens member has a light input surface, a light output surface disposed in front of and spaced apart from the light input surface along an axis, and a through hole extending through the light input surface and the light output surface. Light emitted from the light emitting module enters the lens member through the light input surface and exits the lens member through the light output surface. The decorating unit is detachable and is optically disposed for decorating the lamp or for changing at least one of a wavelength, an output angle, a light field and so forth of the light passing through the lens member.

The present invention relates to a light emitting accessory for a portable terminal and an accessory light emitting system for a portable terminal, and to a light emitting accessory for a portable terminal, which is detachably coupled to the portable terminal to emit light using light of a flash of the portable terminal based on an external signal, a location of the portable terminal, and the like, and an accessory light emitting system for a portable terminal. A light emitting accessory for a portable terminal according to the present invention includes: a fixing unit that is detachably coupled to a portable terminal to cover a flash that is formed on a rear surface of the portable terminal; and a light emitting unit that receives light of the flash from the fixing unit to emit light.

An emergency egress light fixture is disclosed herein. The emergency egress light fixture can include a first light chamber base forming a first light chamber, where the first light chamber base includes at least one first reflector insert coupling feature. The emergency egress light fixture can also include at least one first light source disposed in the first light chamber. The emergency egress light fixture can further include a first reflector insert disposed within the at least one first reflector insert coupling feature, where the first reflector insert divides the first light chamber into a first portion and a second portion, where the at least one first light source is disposed in the first portion, and where the second portion is substantially dark when the at least one first light source is illuminated.

A light emitting diode (LED) module is in thermal communication with front and back heat sinks for dissipation of heat therefrom. The LED module is physically held in place with at least the back heat sink. A mounting ring and locking ring can also be used to hold the LED module in place and in thermal communication with the back heat sink. Key pins and key holes are used to prevent using a high power LED module with a back heat sink having insufficient heat dissipation capabilities required for the high power LED module. The key pins and key holes allow lower heat generating (power) LED modules to be used with higher heat dissipating heat sinks, but higher heat generating (power) LED modules cannot be used with lower heat dissipating heat sinks.

Disclosed are a lighting apparatus and a lighting control system. The lighting apparatus includes a heat radiation frame, at least one light emitting device on the heat radiation frame, a diffusion frame provided on the heat radiation frame to protect the at least one light emitting device and diffuse a light emitted from the at least one light emitting device, and a support frame provided under the heat radiation frame and having a receiving space to receive at least one module. The module includes a wireless communication module to transmit or receive a control single of the at least one light emitting device. The power supply module is physically separated from the wireless communication module.

Provided are an optical sheet holding structure capable of preventing an optical sheet from wrinkling and bending in a display apparatus, and from breakage during a vibration test, thereby preventing occurrence of problems such as uneven luminance, luminance degradation and the like, and a display apparatus including the optical sheet holding structure. A chassis for holding an optical sheet includes an engaging part for engaging the optical sheet. The engaging part includes a base provided to stand on a surface of a holding plate for the optical sheet orthogonally to the holding plate and in the thickness direction of the holding plate, and an engaging portion extending substantially parallel to a holding surface from the front edge of the base toward the outside of the frame of the chassis. A distance between the holding surface of the holding plate for the optical sheet and the surface of the engaging piece facing the holding surface is substantially equal to the thickness of the optical sheet. The cross-section of the base of a central engaging part is formed into a shape substantially identical to the shape of an engagement hole provided in the optical sheet.
