A method for manufacturing a lighting device (100), the method comprising the steps of providing (S1) a sheet of optically transmissive plastic material, forming (S2) a lighting device housing from the sheet of optically transmissive plastic material, such that the lighting device housing comprises a first portion (212) connected to a second portion (214) by a flexible connecting portion (202), folding (S3) the first (212) or second portion (214) about the flexible connecting portion (202) to enclose a light source (210) and driver electronics (206) within an enclosed region of the lighting device housing, and securing (S4) the first portion (212) to the second portion (214) such that the lighting device housing maintains the folded position.

In accordance with various embodiments, a modular lighting system features multiple light panels each having multiple light-emitting elements thereon, as well as connectors for electrically and mechanically interconnecting the light panels.

An LED module with high flame retardant grade includes a base, lens group, flame retardant film and at least one LED luminary unit. The flame retardant film is provided on a first side of the base with at least one hole on the flame retardant film. The LED luminary unit is provided on the first side of the base and passes through the hole with the lens group being covered onto the first side of the base. A first closed space is formed between the lens group and base. The flame retardant film can effectively cut off circuit sparks generated by a circuit layer or by a PCB board on the base, effectively reducing security risks. The module has a high flame retardant grade after being provided with the flame retardant film and the LED module has a simple structure and is easy to process and implement.

A lighting system configured to fit with a box or strip housing and a method of fitting a lighting system with a box or strip housing are presently disclosed. At least one longitudinally extending light source is held with a light source support. At least two hinges extend from the light source support, proximate a first edge, at least two mounting arms extend from the second side of the light source support, proximate a second edge, wherein the first edge and the second edge of the light source support are parallel.

An illumination device includes a sleeve, a securing member, and a light source. The sleeve defines a cavity and includes an open upper end communicating with the cavity and a lower end. The open upper end and the cavity are dimensioned to receive a fluid container. The securing member is supported on the sleeve and is adapted to secure the sleeve tightly about fluid containers having different diameters. The light source includes a light bulb and a power source and is supported on the sleeve in a position to direct light into the cavity.

The present invention relates to a light emitting device comprising a transparent substrate which light can pass through and at least one LED chip emitting light omni-directionally. Wherein the LED chip is disposed on one surface of the substrate and the light emitting angle of the LED chip is wider than 180, and the light emitted by the LED chip will penetrate into the substrate and at least partially emerge from another surface of the substrate. According to the present invention, the light emitting device using LED chips can provide sufficient lighting intensity and uniform lighting performance.

A light guide plate (LGP) includes a positioning block that includes a positioning block body and a liquid filled and hermetically sealed in a receiving compartment formed in the interior of the positioning block body. The liquid is expandable with a drop of temperature so as to increase a volume thereof and thus enlarge a size of the positioning block body through elasticity of the positioning block body. In this way, the LGP positioning block is adjustable with the variation of the surrounding temperature so as to achieve effective positioning of the light guide plate and providing high reliability of a liquid crystal display device including the light guide plate.
