| 20160091179 | LED TUBE LIGHT - An LED tube light having a substantially uniform exterior diameter from end to end is disclosed. It has a glass light tube with narrowly curved end regions at ends for engaging with end caps, in which outer diameter of each end cap is equal to outer diameter of light tube. LED tube light also include a thermal conductive ring. The narrowly curved end region is formed by glass tempering. End caps are joined to the light tube by sleeving over the rear end regions with a hot melt adhesive disposed between the rear end region, the transition region, the insulating tubular part and the thermal conductive ring. An outer diameter of thermal conductive ring is the same as the outer diameter of the main region of the light tube. The transition region is curved, and an outer diameter of rear end region is less than that of the main region. | 03-31-2016 |

| 20160109069 | TUBULAR LED LAMP - The present invention relates to internal use in offices, businesses, production areas, etc. This product could replace fluorescent, incandescent, halogen, and any other type of lamp or luminaire for internal use. The lamp was designed to maximize the air flow and to obtain an adequate heat transfer rate between the lamp and the environment. On the other hand, need to be brought to your attention that some of the component comprising the tubular lamp will be manufactured using Aluminum and/or other appropriate material to increase the heat exchange rate between the lamp and the environment and thus avoid overheating the LEDs to prevent a premature failure. | 04-21-2016 |
| 20160109109 | LED LIGHTING TUBE DEVICE AND METHOD - An LED lighting tube including a heat-dissipating tubular envelope having an LED assembly directly affixed to an inner surface of the heat-dissipating tubular envelope. A method of making an LED lighting tube by providing a heat-dissipating tubular envelope, and affixing an LED assembly directly to an inner surface of the heat-dissipating tubular envelope with an adhesive layer. A method of providing heat-dissipation without a heat sink in an LED lighting tube by providing a heat-dissipating tubular envelope, affixing an LED assembly directly to an inner surface of the heat-dissipating tubular envelope with an adhesive layer, and dissipating heat through the heat-dissipating tubular envelope. | 04-21-2016 |
| 20160131341 | Lighting Assembly - An elongate tubular lighting assembly having a body with a length between spaced first and second ends. The tubular lighting assembly has a source of illumination and first and second connectors respectively at the first and second body ends. The first connector has cooperating first and second parts having first and second surfaces. The first and second connector parts are configured so that the first and second surfaces are placed in confronting relationship to prevent separation of the first and second connector parts with the body in an operative state as an incident of the first connector part moving relative to the second connector part from a position fully separated from the second connector part in a substantially straight path that is transverse to the length of the body into an engaged position. | 05-12-2016 |
