The bulb shell and the light bulb having the same can implements 360 degree omnidirectional illumination with large light-emitting angle and high light-emitting efficiency, and have good heat dissipation performance, thereby increasing the service life of the LED lamp.

The present disclosure discloses a light distribution element and a lamp, the light distribution element is configured to distribute light for a light source, and the light distribution element includes at least two first light distribution modules arranged along a height direction of the light distribution element, the at least two first light distribution modules surround the light source in a circumferential direction, each of the at least two first light distribution modules includes a light incident surface and a light output surface that are away from each other, and the light incident surface is arranged opposite to the light source, each of the at least two first light distribution modules has a divergent light configuration from the light incident surface to the light output surface; and a depression region is between two adjacent first light distribution modules.

The purpose of the present invention is to realize a lighting device which can be switched between an overall lighting and a local lighting with a single lighting device. The concrete structure is a lighting device including: a first light guide having a first major surface and a first back surface, and a first hole; a second light guide, disposed on the first light guide, and having a second major surface, a second back surface, and a second hole; a reflection sheet disposed under the first back surface of the first light guide; a liquid crystal lens disposed above the second major surface of the second light guide, in which first LEDs and second LEDs are disposed circumferentially along a side wall of the first hole and a side wall of the second hole, respectively, and the first LEDs and the second LEDs are displaced each other in azimuth direction.

An end cap for mounting an LED support in a sign cabinet comprises a support-mating portion for mating with an LED support, the support-mating portion including a hollow portion into which an LED support can be inserted and a protruding portion that protrudes into the LED support; and a cabinet-contacting portion opposite to the support-mating portion, the cabinet-contacting portion including a cup section for contacting the cabinet and supporting the end cap and LED support within the cabinet.

The present invention discloses a sector light, said sector light having at least one tier including a light source assembly comprising opaque dividing elements, two or more light sources, and two or more optical lenses; wherein the light source assembly is divided into circumferential sections, each circumferential section being separated by the opaque dividing elements, and each circumferential section containing a light source and an optical lens arranged such that the optical lens collects and outwardly projects the light emitted by the light source.

Simulated flame devices are shown and described having first and second diffusers, each with a sheet having a series of lines etched or embedded on the sheet. A PCB is disposed behind the first and second diffusers and comprises a plurality of light sources disposed or embedded on the PCB. The first and second diffusers may wrap about the PCB to create a 360 degree effect, and the diffusers themselves act to stretch the light emanated from the light sources in a vertical direction. The use of the two diffusers along with changing a brightness of some or all of the light sources over time simulates a moving flame.

A debubbler system includes a hollow enclosure and a vent assembly. The hollow enclosure includes comprising an inlet configured to receive coolant into the hollow enclosure and an outlet configured to direct coolant out of the hollow enclosure. The vent assembly includes a vent member configured to rotate about two or more axes within the hollow enclosure. Additionally, the vent member includes an open end configured to remain above a coolant level within the hollow enclosure as the vent member rotates about the two or more axes and a tube configured to flow air, coolant, or both, from the open end of the vent member out of the hollow enclosure.
