LED tube light
First Claim
1. An LED tube light, comprising:
- a plurality of LED light sources;
a light tube including a main region, a plurality of end regions, and a plurality of transition regions;
an LED light bar, disposed inside the light tube, the LED light sources being mounted on the LED light bar;
a magnetic metal member; and
a plurality of end caps, each of the end caps having an electrically-insulating tubular part;
wherein each of the end caps is sleeved over a respective end region of the light tube, an outer diameter of each end region is less than the outer diameter of the main region, the outer diameter of the main region is substantially the same as the outer diameter of each end cap, each transition region forms a curved region, the magnetic metal member is fixedly arranged on an inner circumferential surface of the electrically-insulating tubular part, and bonded to an outer peripheral surface of the light tube using a hot melt adhesive formed between the outer peripheral surface of the light tube at one end region and the inner circumferential surface of the electrically-insulating tubular part of one end cap, the hot melt adhesive does not spillover through the gap between the one end cap and one of the transition regions, and outer surfaces of the transition regions are under compression and inner surfaces of the transition regions are under tension.

Abstract
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.
