An LED lighting unit comprising a support structure (14), an LED-based light emitting structure (10) mounted within the support structure and an optical beam shaping arrangement (50, 52) over the top of the support structure. The optical beam shaping arrangement comprises an optically transparent and thermally stable material, and the support structure supports the microstructured layer at a small height above the LED-based light emitting structure. This height may for example be less than 0.5 mm. The optical beam shaping arrangement enables a compact and low height lighting unit to be mounted on a carrier by reflow soldering without damaging the optical beam-shaping component.

A cast concrete durable light fixture design and assembly that will allow in-ground lighting features for roadways, pathways and architectural features providing a simple installation for a drive over in-grade or in-ground lighting fixture. The cast concrete design enables curves and shapes to be manufactured as easily as straight or linear configurations.

A backlight module is provided, including: a back frame in a box shape opening at an opening side; a sealant frame within the back frame; and a light guide plate and a membrane on the light guide plate, both surrounded by the sealant frame; the sealant frame has a step structure including a base portion whose upper surface is a step surface facing towards the opening side and a surrounding wall; the sealant frame has at least one positioning notch recessed into the base portion and the surrounding wall; the membrane has at least one positioning lug at an edge thereof, below the step surface and extending into the positioning notch; and the backlight module includes at least one positioning insert within a respective positioning notch and having a plate piece whose upper surface being an auxiliary supporting surface facing towards the opening side and flush with the step surface.

An LED growth light and method for providing light to plants incorporating an LED arrangement, a growth light housing, and a power source. The LED arrangement includes LEDs arranged in individually powered columns to provide relatively uniform disbursement of the light to the plants. The housing includes an accessory rail to attach a variety of optional accessories and internal cooling fins to cool the housing to prevent damage to the power supply and/or to prevent overheating the plants. In addition, the housing includes a fan and end caps which permit the movement of air for the displacement of heat and reduce the intake of moisture or debris into the interior of the LED growth light.

A luminous pad connected to a transmitter includes a pad body, a light guide strip, a light source module, an electrical object, and a pad surface stitch. The pad body has two pad surfaces; the light guide strip has first and second positions and surrounds the pad body; the light source module is installed at the first position and connected to the transmitter; the electrical object is installed at the second position; a pad surface stitch of a conductive wire is sewed between the two pad surfaces and connected between the electrical object and transmitter, so that the electrical object and transmitter are electrically conducted with each other through the pad surface stitch. This disclosure has the effects of transmitting electric power and/or signals to the electrical object through the pad surface stitch by the transmitter and maintaining the aesthetic appearance and ensuring the flatness of the luminous pad.

In some aspects of the disclosure, an attachable lighting device has a lighting assembly which includes a light housing, an attaching base, and one or more optical sources. The light housing is attached to the top of the attaching base and contains the one or more optical sources. The attachable lighting device has a receiving base which is attachable to an attachment surface of a boat. The attaching base is attachable to the receiving base.

Disclosed is a mini light emitting diode backlight module, comprising a light emitting diode light source and a fluorescent film layer, wherein the light emitting diode light source comprises a substrate and mini light emitting diode lamp beads arranged in an array on the substrate, and the fluorescent film layer is disposed in a light emitting direction of the light emitting diode light source, and a surface of the fluorescent film layer toward the mini light emitting diode lamp beads is provided with grooves arranged in an array. By designing the fluorescent film layer having a specific shape, and placing the same in front of the mini light emitting diode lamp beads, the light leakage can be avoided and the light path can be changed to solve the problem of hotspot and light leakage around in the mini light emitting diode backlight module.
