A light source unit in a backlight module able to resist the accumulation of static electricity includes a circuit board, a plurality of lighting elements, a plurality of conductive lines, and at least one connecting line. Each conductive line electrically connects with lighting elements. The conductive line forms a plurality of first sharp portions. A plurality of second sharp portions which are grounded are facing the first sharp portions. The first sharp portions collect static electricity and the second sharp portions cooperate with the first sharp portions to discharge the static electricity.

Apparatus and methods for lighting. The apparatus may include an LED light source. The light source may be disposed in housing. The apparatus may include a circuit. The circuit may be configured to cause the LED light source to emit light at: a first intensity; and a second intensity that is different from the first intensity. The apparatus may include a mechanical power state selector. A user may use the power state selector to select between LED light sources that are arranged to illuminate in different directions. The apparatus may include a CCT state selector. A user may use the CCT state selector to select a CCT for one or more LED light sources. The CCT may be produced by combining light from one or more LEDs of different CCTs.

The current invention applying super slim LED-unit(s) has built-in contactors has (a) magnetic only or (b) conductive magnetic-movable-kits so can attach or detachable metal magnetic-field reactive buss-strips. The conductive-movable type which also can deliver electric current from buss-strips of track light. The super slim LED light or units is a DC powered LED light has optics design become super thin and none bright-spots. The said LED-units install under the light-block material housing or parts, and light-beam go through at least of reflective surface at inner surface or walls. The said LED-unit install on hard or bendable circuit board with divider the compartment only has LED, lit-lens, reflective housing. The compartment is only space where light-beam traveling and has multiple times reflected and emit out from top lens. The said light beam emit out from LED-unit(s) reflected by high reflective surface or wall including (1) white high-polished plastic or (2) metalized mirror-like or (3) shining metal piece back-and-forth and light emit out from top lens. The current invention has multiple time reflective and refractive optic theory to make the super thin light for SMD LED(s) on hard or bendable PCB to get in-direct light beam. To get none bright-sports by not install LED(s) under face top lens. The Track LED light or LED-unit has slim features with different size can use as ceiling, closet, kitchen, laundry, door, garage, patio or anywhere for building, residence, house for indoor or outdoor use.

A device for an illuminated balloon includes a light emitting diode. A holder is connected to the light emitting diode, the holder having a first side, an opposite second side, and a hole which receives the light emitting diode, the hole extending from the first side to the second side. The holder is connectable to the inside surface of the balloon, so that the light emitting diode points out from the balloon. When so connected to the balloon, the longitudinal axis of the light emitting diode is oriented substantially perpendicular to the surface of the balloon. In an embodiment the holder is disc shaped, is fabricated from foam, and is connected to the inside surface of the balloon by an adhesive.

A light-emitting device comprises a casing including an upper surface portion having one or more first through holes, and a front surface portion having an opening; a transparent member that closes off the one or more first through holes; one or more light-emitting elements that face the one or more first through holes, respectively, within the casing; and a lid member provided so as to close off the opening, wherein the casing is integrally formed using one material.

In a door mirror device for a vehicle, a projector protrudes out toward a lower side from a circuit board, and the projector projects a pattern onto a ground surface. Moreover, illuminating LEDs and guide bodies are fixed to a lower surface of the circuit board. Due to the illuminating LEDs generating lights and the guide bodies guiding these lights, the guide bodies irradiate the lights from lower ends, and the ground surface is illuminated. Here, the lower ends of the guide bodies are disposed further toward a lower side than the projector. Therefore, shadows, which are due to the projector, arising in lights that illuminate the ground surface can be suppressed.

A method for manufacturing a light-emitting device includes: providing a base including a first depressed portion and a second depressed portion both upwardly opening; and positioning and mounting at least one semiconductor laser element on or above the base based on a predetermined point on a line connecting the first depressed portion and the second depressed portion in a plan view.

A lighted tile for false panel, including a frame having a bottom and sides that extend projecting from the bottom, a backlighting system having a series of lights attached to the bottom, and a stretched flexible sheet that extends between the sides facing the lights. The lights are light-emitting diodes, and the sheet is secured to the sides of the frame.

A light-emitting device includes a surface-light-emitting unit, a substrate, a holding sheet, and a sealing sheet. The surface-light-emitting unit has a light-emitting surface and a non-light-emitting surface, and emits light from the light-emitting surface. The substrate has a mounting surface and a non-mounting surface provided to be flush with the light-emitting surface, and has a power source mounted on the mounting surface. The holding sheet is provided to face the non-mounting surface and the light-emitting surface provided to be flush with the non-mounting surface. The sealing sheet is disposed on the side opposite to the holding sheet with respect to the surface-light-emitting unit and the substrate, and provided to cover the surface-light-emitting unit and the power source. The light-emitting device is disposed so that the holding sheet comes to the installation surface side. With such a structure, the light-emitting device that can be stably disposed on the installation surface is provided.

A cordless, battery powered lighting device is disclosed which is configured to be removably installed on a distal end portion of a handheld electrosurgical instrument, and once the lighting device is installed on the distal end portion of the instrument, light automatically projects from the lighting device along the longitudinal axis of the surgical instrument.
