Abstract: A light device having a battery and lamp housing and a hinged top door. Batteries and a lamp holder are located within the housing and are accessible by opening the hinged top door. As the hinged top door is opened, a cam surface that holds the batteries in tight contact with the lamp holder moves away from the batteries, thereby releasing the tension holding the batteries in place within the housing. The batteries can therefore be easily loaded and unloaded. Likewise, as the hinged top door is closed, the tension holding the batteries in place is reapplied to the batteries to create a circuit for powering a lamp engaged with the lamp holder. Furthermore, the lamp engaged with the lamp holder is also accessed through the hinged top door.

The spaces between the LEDs are utilized for light passage.

Abstract: A headlight for use on a head gear, or the like, is provided. A LED serves as a light source mounted on a clamp for attachment to the head gear in any one of the three orientation planes. A universal mount of the light source on the clamp allows the light beam to be directed by up and down, as well as by side-to-side, manual adjustment. The beam covers substantially all frontal objects without changing the position of the clamp. A pair of pivot connections, or a ball and socket mechanism, exhibit sufficient frictional engagement to hold the light source in position. The pivot connection may be used to support the ball on the light source in the second embodiment. The socket is split along its curvature lines and an O-ring extends around the split socket to assure frictional engagement to hold the light source in position.

The light reflection pattern comprises a plurality of arced grooves and is configured such that the grooves have their depths increasing with an increase in the distance from the light source, and that each of the grooves has its depth increasing with an increase in the light emission angle made by a line of a light emission direction with respect to a diagonal line from the light source. Thus, the light reflection pattern is adapted to reflect more light at an area farther from the light source and the diagonal line as well, thereby further improving uniformity in brightness all over the light conductive plate.

The LED module includes linear arrays of LEDs supported by support arms having mounting mechanisms for engaging with the housing sidewalls. The mounting mechanisms include scissor arms rotatably attached together about mid-portions thereof, and a tightening screw that adjusts the distance between the scissor arm ends to press engagement surfaces of the scissor arms against the housing sidewalls. Adjustment screws at the lower ends of the support arm can be adjusted to further extend the engagement surfaces, so that a single LED module can be installed inside a wide range of backlit sign sizes. The retrofit method includes removing the conventional fluorescent lamp from the backlit sign, and installing the LED module using the scissor arm mounting mechanisms.

Abstract: The invention relates to a chemiluminescent light element having at least two chambers, filled with an oxalate solution and an activator solution, or variations of known chemiluminescent light materials including dyes. The oxalate solution is placed within a tight-sealed pouch made of thin aluminum foil lined on its interior side by a polymer, for instance a polyolefin, and so forms the first chamber. This latter is enclosed in a bigger tight-sealed pouch made of translucent polymer film forming the second chamber, which also contains the liquid activator. The outer pouch consists of two polymer films sealed together along their periphery and contain a ball able to pierce the inner pouch by manual action from the user.
