An LED lamp, comprising a base; a lamp envelope coupled to the base; a support module accommodated in the lamp envelope, a first inner cavity being formed between the support module and the lamp envelope, the first inner cavity containing therein a first gas medium; a driver module accommodated in the first inner cavity and coupled to the support module; and an LED inner vessel accommodated in the first inner cavity and coupled to at least one of the support module and the driver module, a sealed second inner cavity being formed within the LED inner vessel, and the second inner cavity containing therein a second gas medium and an LED light source module.

An LED lighting fixture includes a housing, a substrate located within the housing, a plurality of LED groups of various colors mounted on the substrate, each LED color group including multiple LED components, at least one circuit communicating with a power supply and adapted for powering the LED components, and an optical component located at an output end of the housing. The LED components are arranged along first and second directions orthogonal to one another, such that no two LED of the same color reside adjacent one another along both of the first and second directions, and each LED component is spaced-apart from an adjacent LED component a distance no greater than 1.0 mm.

A light-emitting device and a bulb include a light engine structure. The light engine structure includes a first seal cavity and a light source which is provided in the first seal cavity. The first seal cavity filled with an insulating liquid or gas. The light source is exposed to the insulating liquid or gas. A second seal cavity is provided outside the first seal cavity, which is filled with an insulating liquid or gas. This invention provides a sealed light-emitting engine filled with heat-dissipating liquid or gas, in which a second layer of sealed heat-dissipating structure is disposed outside the light-emitting engine, and the die structure exposed to the heat-dissipating liquid or gas, which solves the heat-dissipating problem of lamps. Furthermore, a design of the light-emitting engine provides a foundation for various applications of bulb lamps, and solves defects of cost and light efficiency of common bulb lamps at present.

The present disclosure relates generally to a “clocking” mechanism that give customers the flexibility to adjust light output distribution of luminaires to a desired level. The “clocking” mechanism gives the flexibility to adjust a position of a retainer ring of a LED system with respect to a mounting module that includes a heat sink adapter housing.
