    Abstract: A dual LED light fixture is comprised by a lower LED light source housing and an upper LED light source housing. A lower LED light source is mounted in the lower light source housing to generate downlight. An upper LED light source is mounted in the upper LED light source housing and remote from an outer circumferential light transmitting outer side area of the upper light source housing and from which is emitted side light illumination. An LED power supply and light control circuit mounted in the LED light fixture and adapted for connection to a power source. The LED light power supply and control circuit has a dimming circuit and a lower and upper driver current supply circuit. A switch is operative to connect driver current to the upper LED light source when actuated to an “on” position and to disconnect driver current to the upper LED light source when in a normal “off” position. The switch is operative for engagement to its “on” position when desirable to provide drive current to the upper light source and illumination from both the lower and upper LED light sources of the LED light fixture. Various embodiments of the LED light fixture is described.

    Abstract: A lighting device with improved luminous performance is provided, which includes a first light path, a second light path and a plurality of first light sources and second light sources. The first light path includes a plurality of first bending portions and second bending portions arranged in staggered arrangement. Each first bending portion and each second ending portion protrude from one side and the other side of a first reference line respectively. The first light sources are distributed over the second bending portions. The second light path is connected to the first light path in parallel, and includes a plurality of third bending portions and fourth bending portions arranged in the staggered arrangement. Each third bending portion and each fourth bending portion protrude from one side and the other side of a second reference line respectively. The second light sources are distributed over the third bending portions.

    Abstract: A vat polymerization printer may comprise a tank assembly for containing a photo-curing liquid resin. The tank assembly may include a tank sidewall and a tank bottom formed by a membrane assembly. The membrane assembly may comprise a radiation-transparent flexible membrane and a frame affixed to a perimeter of the radiation-transparent flexible membrane. In one embodiment, the radiation-transparent flexible membrane may include a radiation-transparent flexible substrate sandwiched between two fluorinated ethylene propylene (FEP) films or two polyolefin polymer films. In another embodiment, the radiation-transparent flexible membrane may include an FEP or polyolefin polymer film bonded to a layer of silicone rubber at a first side of the layer of silicone rubber, the layer of silicone rubber having a coating on a second side thereof. The vat polymerization printer may also comprise an OLED light source.
