A light diffusing film for a back light display is described. The light diffusing film includes a unitary film consisting essentially of polycarbonate and a uniformly dispersed anti-static material in an amount sufficient to impart anti-static properties to the film. The anti-static material may comprise a fluorinated phosphonium sulfonate. The film may additionally include at least one textured surface for the low scattering of light. Alternatively, the film may additionally include a uniformly...

An aircraft forward position lighting device (1) has a modular configuration, including a mounting module (20) containing solid-state light sources, e.g., light-emitting diodes (LEDs) (210, 230). The mounting module also includes reflectors 220. The pattern of light emanating from the light sources and reflectors satisfy Federal Aviation Regulations (FARs) regarding minimum light intensity. The device includes a cut-off shield module (10) configured to provide angular cut-offs to the pattern of ...

A night light comprising a housing with a rotatable bezel mounted thereon. The housing includes a rear wall with electric blades extending outwardly therefrom for engaging in an electrical wall outlet. The bezel is rotatable about a first pivot axis. A LED array is mounted in the bezel and the array is rotatable about a second pivot axis. The second pivot axis is oriented on a different plane to the first pivot axis and preferably lies at ninety degree thereto. When the bezel is rotated about th...

A quickly deployable and reconfigurable light emitting diode (LED) lighting apparatus with high output intensity and precisely controlled beam property is disclosed for navigational aids. The lighting apparatus comprises an array of high intensity LED units with their light beams individually controlled by secondary optical systems. The transformed light beams mix in a pre-determined manner to produce an illumination pattern with desired intensity distribution. The LED lighting apparatus may fur...

Also described is a battery configured to provide an electrical current to a helmet system, an electrical distribution system configured to provide a path for the electrical current between the battery and the ...

A tubular Electro-Luminescent light device offers desired bending directions with super brightness based on the predetermined width of a panel incorporated with a proper inverter system. The panel has a much narrower width than a tube means containing the panel to allow the panel to bend in any direction and angle within the tube means to provide desired light effects. The panel can be flat or twisted within the tube means, which in turn may have a desired colored, transparency, wall thickness, ...

An orthogonal array backlight module includes multiple fluorescent tubes paved on both inner sides of a light box, and a display panel comprised of diffuser plate, optical film and liquid crystal panel being provide on the top of the light box; and each fluorescent tube being significantly shorter than that of the prior art of same size to effectively provide consistent luminance and allow easier assembly.

An indicator device is intended to make an indication by illuminating a predetermined indicating surface, and comprises a light source (12) for emitting a light (L1) of the first wavelength and a fluorescent plate (22) disposed between the light source and the indicating surface for changing at least part of the light of the first wavelength projected from the light source into a light (L2) of the second wavelength longer than the first wavelength and projecting it towards the indicating surface...

A flashlight having a magnet incorporated into the electrical circuit of the flashlight. This flashlight may further include a flexible member which either is provided with a light or conducts light, which flexible member is also provided with a magnet for coupling with the magnet in the circuit.

The present invention relates to a portable apparatus including a fastening mechanism for use with the light-emitting disk. The clamping area of the light-emitting disk has a plurality of conductive terminals, and the touch portion of the fastening mechanism connected with the conductive terminals can supply electrical power to light up the light-emitting disk. Furthermore, the light-emitting disk can light partially, intermittently or colorfully by itself because the fastening mechanism control...
