A light bulb includes a housing, an illuminating component, a driving circuit board, a light transmitting component and a lens. The housing has a circumferential opening and a cavity chamber therein. The illuminating component is disposed within the cavity chamber. The driving circuit board is disposed inside the cavity chamber. The driving circuit board is also electrically coupled to the illuminating component. In addition, the driving circuit board drives the illuminating component while being powered up. The light transmitting component is disposed within the cavity chamber and affixed to the illuminating component. The light transmitting component includes a plurality of transmitting microstructures on its surface that uniformly distribute lights emitted from the illuminating component along an axial direction of the light bulb. The lens is disposed within the cavity chamber. The lens also focuses the uniformly distributed lights on a predetermined range along the axial direction of the light bulb.

A lighting fixture includes a housing, a light source, an optics array, and control circuitry. The housing includes an opening through which light is provided from the lighting fixture towards an area of interest. The light source is in the housing and includes a number of solid-state light sources. The optics array is also in the housing and includes a number of optics. Each optic in the optics array is configured to focus light from each one of the light sources into a number of beams of light such that each one of the beams of light is provided through the opening of the housing at a different angle. The control circuitry is configured to selectively illuminate the number of solid-state lighting sources such that a direction of light provided by the lighting fixture dynamically changes over time.

A light fixture with a troffer design. The light fixture includes a housing, LED assembly, and lens assembly. An inner lens can be positioned over the LED assembly to control the distribution of light. A reflector can be positioned over the LED assembly instead of the inner lens to control the light.

A light emitting device (LED-Filament) comprises: a light-transmissive substrate; at least one blue LED chip mounted on the light-transmissive substrate, for instance mounted on a face thereof; and a photoluminescence material at least partially covering the at least one blue LED chip. The photoluminescence material comprises narrow-band red phosphor particles that generates light with a peak emission wavelength in a range of 600 nm to 640 nm and a full width at half maximum emission intensity of 50 nm to 60 nm. The light emitting device is characterized by CRI Ra greater than or equal to about 90. The narrow-band red phosphor particles can comprise at least one Group IIA/IIB selenide sulfide-based phosphor material such as for example CaSe.sub.1−xS.sub.x:Eu (CSS phosphor). The LED-filament can be incorporated in a lamp, with a yellow to green-emitting phosphor that generates light with a peak emission wavelength in a range of 520 nm to 570 nm, to provide light with a color temperature in a range of 1500 K to 4000 K or 1500 K to 6500 K and a General Color Rendering Index (CRI Ra) greater than or equal to about 90 and a CRI R9 greater than or equal to about 50.

A body, such as a lamp body, includes a tubular element. At least one conductor is introduced into the tubular element and a glass material surrounds the conductor. The glass material forms a seal between the tubular element and the conductor. The glass material includes a sintered glass, such as a sintered glass ring, and may completely surround the conductor.

A light source module includes a light source, first and second lens elements, a reflector, and a first diffuser. The light source emits a beam focused by the first lens element on a first focal point. The reflector is disposed on a beam transmission path. The first lens element is between the light source and the reflector. The first diffuser is between the first lens element and the reflector and includes a first diffusion plate and a first drive mechanism. The first diffusion plate is at/near the first focal point. The beam is transmitted to the reflector by the first diffusion plate. The first drive mechanism is between the first diffusion plate and the first lens element, and moves/rotates the first diffusion plate. The second lens element has a second focal point, coinciding with the first focal point, at a light-incident side. The reflector is at the light-incident side.

An illuminated lighting stand has a lighting fixture head mount, a bottom base, and an elongated, upright illumination pole extending between the head mount and the bottom base. The illumination pole consists of an elongated, upright skeletal support pipe, RGB tape surrounding the support pipe, diffusing material circumscribing the RGB tape, and a transparent outer tube covering the diffusing material, all these elements extending the length of the illumination pole. An electrical power supply and Wi-Fi electronics are housed within the base to illuminate and control the illumination sequencing and functioning of the light stand.

An LED tube lamp includes a glass lamp tube, two end caps, an LED light strip, a power supply, and a diffusion film. The glass lamp tube includes a main body region and two rear end regions, each of the two rear end regions coupled to a respective end of the main body region and each of the two end caps coupled to a respective rear end region. A length of the light strip is longer than the length of a main body region of the glass lamp tube. Each of the two end caps is coupled to a respective end of the glass lamp tube by a adhesive. The LED light strip is attached to an inner circumferential surface of the glass lamp tube with a plurality of LED light sources mounted on the LED light strip. The diffusion film is disposed on an out surface of the glass lamp tube.
