An LED light bulb includes a bulb shell, a bulb base, two conductive supports, a stem, two supporting arms, and an LED filament. The bulb base is connected with the bulb shell. The two conductive supports are disposed in the bulb shell. The stem extends from the bulb base to inside of the bulb shell. The two supporting arms are disposed in the bulb shell. The LED filament includes a plurality of LED chips arranged in an array and two conductive electrodes respectively disposed at two ends of the LED filament and connected to the LED chips. The two conductive electrodes are respectively connected to the two conductive supports. A direction of a first highest curved portion of the LED filament and a direction of a second highest curved portion of the LED filament are substantially opposite to a direction of a lower curved portion of the LED filament.

An LED light module comprises an emitting portion; at least one LED package; a back cover; and an end cap. The emitting portion defines a first curved surface. The first curved surface extends a first length along a cylindrical axis defined by the LED light module. The back cover defines a second curved surface extending the first length along the cylindrical axis. The first curved surface and the second curved surface define a perimeter of the LED light module. In a cross-section of the LED light module taken in a plane substantially perpendicular to the cylindrical axis, the perimeter is substantially ovular, elliptical and/or tear-drop shaped. The end cap is substantially ovular, elliptical and/or tear-drop shaped, and comprises a coupling element configured to electrically and/or mechanically couple the LED light module to a subsequent LED light module or to a fixture.

The disclosure provides a portable light. The portable light includes a housing having a front surface, a rear surface, and an internal space for receiving electronic components and a battery. The portable light also includes a chip-on-board (COB) assembly. The COB assembly includes a substrate, a matrix of individual light emitting diode (LED) chips mounted to the substrate, and an outer coating covering the matrix of LED chips. The front surface of the housing is curved in one direction and the COB assembly is correspondingly curved and mounted to the front surface, such that individual LED chips are positioned about the curve and orientated to direct light outwardly about the curve to provide a collective beam angle greater than 220 degrees. The portable light further includes a front lens cover to protect the COB assembly.

An LED light bulb includes a bulb shell, a bulb base, two conductive supports, a stem, and an LED filament. The bulb base is connected with the bulb shell. The two conductive supports are disposed in the bulb shell. The stem extends from the bulb base to inside of the bulb shell. The LED filament includes a plurality of LED chips and two conductive electrodes. The LED chips are arranged in an array along an elongated direction of the LED filament. The two conductive electrodes are respectively disposed at two ends of the LED filament and connected to the LED chips. The two conductive electrodes are respectively connected to the two conductive supports. The LED filament is curled to satisfy symmetry characteristics.

A solid state lamp includes a connector and a bulb portion with multiple strips.

A light fixture includes a visible light module and a germicidal light module. The visible light module may include one or more visible light engines designed for emitting visible light for general illumination. The visible light module may define a top side, a bottom side opposite the top side, and an outer perimeter around the top side and the bottom side. The visible light module may define an aperture extending through the visible light module from the top side to the bottom side. The visible light module may be designed to emit the visible light out of and across the bottom side from the outer perimeter to an inner perimeter defined by the aperture. The germicidal light module may be coupled to the visible light module. The germicidal light module includes a germicidal light engine designed to emit germicidal light through the aperture effective in deactivating pathogens.

A white-light LED module is disclosed. The white-light LED module includes a substrate, and a red-light LED chip string, a blue-light LED chip string, and a green-light LED chip string arranged on the substrate. The red-light LED chip string, the blue-light LED chip string, and the green-light LED chip string are connected in parallel. A number of blue LED chips within the blue-light LED chip string equals to the number of green LED chips within the green-light LED chip string. The number of red LED chips within the red-light LED chip string is as double as the number of blue LED chips and the green LED chips. In this way, the light mixture performance of the red, green and blue LED chips may be enhanced.

A light emitting diode (“LED”) light fixture includes a base including contacts for connecting to an electrical power supply, a plurality of LED disposed on a stand coupled to the base, and a protective shell coupled to the base for protecting the stand from being contacted by a foreign object. The LED stand might be an elongated spherical shaped ball, or a polygonally shaped prism.
