The supporting back plate is disposed between the second casing and optical member. The supporting back plate includes a first area and a second area. A distance from the first area to the second casing is greater than a distance from the second area to the second casing. The circuit board is disposed on the first area of the supporting back plate. The lights are disposed on the supporting back plate.

A lamp, a hanging transparent lamp and a lamp system are provided. The lamp includes a frame body, a light guide plate, a light source and a circuit assembly. The frame body includes side covers, side bars, a first integrating member and a second integrating member. Each of the side covers comprises a carrying portion. Each of the two side covers is partitioned into an upper space and a lower space by the side bar. The light guide plate is held on the carrying portions. The light guide plate has a first light-emitting surface and a second light-emitting surface. Only side edge portions of the first light-emitting surface and the second light-emitting surface are covered by the frame body. The light source is disposed adjacent to the side surface of the light guide plate. The circuit assembly is connected to the light source to form an electrical loop.

Systems and methods are disclosed for a light cover that may include a blocking portion configured to block a light emitted from a light-emitting diode, the blocking portion having a first shape associated with a heated state in which the blocking portion extends vertically in parallel with a lower portion of an optical sheet, the first shape configured to minimize a gap between the lower portion of the optical sheet and the blocking portion; a mounting portion configured to contact a bottom portion of a cover bottom of the display, the mounting portion extending orthogonally from the blocking portion; and a plurality of mounting pegs disposed on interior portions of the mounting portion, each of the plurality of mounting pegs configured to removably couple the mounting portion of the light cover to the bottom portion of the cover bottom.

A lighting fixture includes a housing, a first light source, a light guide plate, and a second light source. The housing has an inner cavity and a mounting hole, the mounting hole communicates the inner cavity with an external environment of the housing, the light guide plate is installed in the mounting hole. A side of the light guide plate faces the inner cavity, the other side of the light guide plate faces an outside of the housing. The second light source projects second light to the light guide plate, the second light is capable of being projected to the outside of the housing through the light guide plate. The first light source projects first light, and is configured such that the first light is projected to the outside of the housing through the light guide plate, and the housing is a non-light-transmitting housing.

An improved LCD backlighting unit (“BLU”) particularly a BLU which uses light emitting diode (“LED”) light sources especially white LED light sources, enhances a liquid crystal display's (“LCD's”) readability in sunlight. The improved BLU briefly increases a display screen's brightness, typically 2-6× greater than a BLU's maximum continuous operating brightness. The BLU and its associated LED driver provide substantially increased brightness for a predefined and relatively short interval, typically 2 to 60 seconds, without damage. The LED driver control prevents boosting the display brightness too frequently or for too long thereby avoiding system damage by adequately dissipating the increased power. The BLU may include a thermal sensor on or near the LEDs to provide real time temperature feedback to the LED driver control. Temporarily boosting the BLU's brightness helps any outdoor daylight application such as commercial drones where the sun can easily wash out a display an the drone's controller.

A reflector laminate comprises a reflector having a first major surface and a second major surface opposite the first major surface, and a visible light non-transmissive adhesive tape having a major adhesive surface and a second major surface. The adhesive surface is in contact with the first major surface of the reflector and at least a portion of the adhesive tape extends beyond the edge of the reflector.

A light mixing module, a display device having the light mixing module, and a design method for the light mixing module are provided. The light mixing module includes a main substrate with a printed circuit, and at least one chip-level light emitting unit arranged on the main substrate. The chip-level light emitting unit includes a LED chip, a backlight bracket, a shading element and a supporting element. The backlight bracket is mounted on the main substrate, and the backlight bracket has a cup-shaped reflecting surface surrounding the LED chip. The shading element is suspended right above the LED chip by the supporting element.

A backlight board and a liquid crystal display apparatus are disclosed. The backlight module includes a plastic frame and a square-shaped adhesive tape. The plastic frame has an attachment surface on the top surface of the plastic frame. The attachment surface includes a first attachment sub-surface and a second attachment sub-surface. The first attachment sub-surface is parallel with a light-exiting surface; the second attachment sub-surface is connected to an end of the first attachment sub-surface, and is at a predetermined angle in relation to a plane on which the first attachment sub-surface is disposed. A portion of the square-shaped adhesive tape that may extend outwardly from an edge of the plastic frame can be attached to a transitional surface to avoid extending out of the plastic frame.

A backlight module comprises a back plate, a reflective sheet arranged on the back plate and forming a plurality of openings, a plurality of light-emitting elements located in the plurality of openings, at least one optical element arranged on the reflective sheet, and at least a supporting element configured between the back plate and the reflective sheet. The supporting element can move along with the reflective sheet. The supporting element has a base portion and a supporting portion extending from the base portion towards the optical element. The base portion of the supporting element is located between the back plate and the reflective sheet. The supporting portion of the supporting element passes through the reflective sheet to support the optical element. The supporting element is not a fixed design and can move along with the reflective sheet. Therefore, other plates under the reflective sheet do not require openings, which can improve assembly convenience and effectively reduce the mechanism interference caused by the expansion and contraction of the reflective sheet. The invention also provides a display device including the backlight module.
