An LED control system is provided for connection to an LED lighting system via a power line to control the LED lighting system using commands formed by manipulation of frequency and amplitude of a signal transmitted over the power line. The signal may be for example a wave or a sequence of pulses. The signal may be provided in superposition with line power or the line power may be formed as the signal.

An apparatus to produce a letterbox using a strip of material includes: a bender to receive and bend the strip of material into a desired shape of a letterbox including flanges and notches, and the bender to bend at least one end of the strip of material slightly to produce a slight bent; a processor to measure a first plurality of hole positions on a first end of the strip of material and a second plurality of hole positions on flanges of the strip of material, wherein the first plurality of hole positions on the first end are measured to match a first plurality of holes on a second end of the strip of material, wherein the second plurality of hole positions on the flanges are measured to match a second plurality of holes on a base plate; and a puncher to punch the first plurality of holes on at least one of the first end and the second end of the strip of material according to the first plurality of hole positions, and the puncher to punch the second plurality of holes on the flanges according to the second plurality of hole positions.

An illuminating vehicle assembly includes a plastic grille component and a badge mounted to the plastic grille component. The badge houses at least one light source. The light source may be illuminated to create various lighting effects. Any heat generated by the at least one light source can be dissipated into the plastic grille component.

A vehicle lighting system is provided primarily for use with emergency response vehicles. The vehicle lighting system includes at least one luminescent planar sheet affixed to a vehicle's mounting surface. The luminescent planar sheet includes a non-luminescent printed circuit board in the shape of a letter or number which has a top surface of a color which contrasts with the mounting surface's color. The luminescent planar sheet includes a plurality of light emitting LEDs which are surface mounted upon the printed circuit board so as to be arranged in the shape of the desired letter or number with the LEDs covering no more than 20% of the printed circuit board's top surface. Preferably, the LEDs cover no more than 7% the printed circuit board's top surface.

The invention relates to a lighting display system (1), comprising: a mounting structure (3), which comprises a mounting plate (7) having a front side (13); at least one first plug contact (15) arranged on the front side (13) of the mounting plate (7); and an electrical power supply connection (17), which is electrically connected to the at least one first plug contact (15); at least one luminous body (5), which comprises a front side (19) and a back side (21); a second plug contact (23), which is arranged on the back side (21) of the at least one luminous body (5) and which can be plugged together with and electrically connected to the first plug contact (15); and a plurality of light sources (27), which are electrically connected to the second plug contact (23); wherein the at least one luminous body (5) can be secured to the mounting structure (7) by means of least one securing assembly (29), wherein a first element (31) of the at least one securing assembly (29) is firmly connected to the back side (21) of the at least one luminous body (5), a second element (33) of the at least one securing assembly (29) is firmly connected to the front side (13) of the mounting plate (7), and a third element (35) of the at least one securing assembly (29) is configured to connect the first and the second element of the at least one securing assembly (29) to each other in a positive-locking manner.

A three-dimensional display device is provided with at least three elongated support legs. The legs are oriented and peripherally spaced around a central vertical axis forming an open leg cavity between the support legs, allowing for unobstructed passage of light through the cavity. The outer surface of each of the support legs defines a plurality of notches spaced longitudinally along the outer surface of each support leg, and the notches are adapted to receive and to secure against movement relative to the leg a portion of an elongated flexible light emitting tubular member, forming a three-dimensional helical patterned illumination.

A dual-use side-lighting netting lamp box with a box body. The box body has a top frame structure and a bottom frame structure. The top frame structure is formed by assembling short cross rod profiles and long cross rod profiles through top netting fixing blocks; and the bottom frame structure is formed by assembling short cross rod profiles and long cross rod profiles through bottom netting fixing blocks. A table surface at the top of the lamp box adopts a detachable structure, so that the lamp box can be used as not only a lamp box table when the table surface is placed normally, but also a single lamp box when the table surface is removed. Thus, the dual-use function is realized, the functionality of the lamp box is obviously improved, and the resource utilization rate is high.

An illuminating vehicle assembly includes a plastic grille component and a badge mounted to the plastic grille component. The badge houses at least one light source. The light source may be illuminated to create various lighting effects. Any heat generated by the at least one light source can be dissipated into the plastic grille component.

A lighting device for use on apparel includes a main body portion and a raised graphic portion at the front of the main body. Inside the device there is a graphic element in the raised portion that is translucent. Behind the graphic element and inside the main body of the device there is one or more lighting elements, a control circuit, and a battery. There is a power connector at a side of the main body, or in a remote connector, to charge the battery, and one or more switches either at the side of the main body or on the remote connector to allow a person to control the lighting operation of the device. The device is molded in the form of the graphic element and the graphic element, lighting element, battery, and circuitry are embedded in the molded body.
