LED tube light with diffusion layer
First Claim
1. An LED tube light, comprising:
- a plurality of LED light sources;
an end cap;
a light tube, having a first end attached to the end cap; and
a diffusion film layer,wherein the diffusion film layer is disposed above the LED light sources so that light emitted from the LED light sources is transmitted through the diffusion film layer and the light tube; and
an optical diffusion coating having an outer surface and coated on an outer surface of a rear end region of the first end of the light tube, wherein;
a hot melt adhesive is bonded to the outer surface of the optical diffusion coating, andan increased frictional resistance is generated between the end cap and the light tube due to the presence of the optical diffusion coating when compared to the frictional resistance between the end cap and the light tube without any optical diffusion coating.

Abstract
An LED tube light, including LED light sources, end cap, a light tube, a diffusion film layer and a reflective film layer is provided herein. Diffusion film layer is disposed above LED light sources so that light emitted from LED light sources are transmitted through diffusion film layer and light tube. Diffusion film layer can also be optical diffusion coating coated on wall of light tube, and coated to an outer surface of rear end region of light tube, a hot melt adhesive is bonded to outer surface of optical diffusion coating to generate increased frictional resistance between end cap and the light tube. Reflective film layer is disposed on inner circumferential surface of light tube, and occupying a portion of inner circumferential surface of light tube along circumferential direction thereof. LED light sources are disposed above or adjacently to one side of reflective film layer.

19. An LED tube light, comprising:
-
a plurality of LED light sources; two end caps; a light tube, having two ends respectively attached to the two end caps; and a first diffusion film layer, wherein the first diffusion film layer is disposed above the LED light sources so that light emitted from the LED light sources is transmitted through the first diffusion film layer and the light tube, wherein a second diffusion film layer is disposed on an outer surface of a rear end region of a first end of the light tube, and a hot melt adhesive connecting the light tube to each end cap is bonded to an outer surface of the second diffusion film layer, and wherein an increased frictional resistance is generated between each end cap and the light tube due to the presence of the second diffusion film layer when compared to the frictional resistance between each end cap and the light tube without the second diffusion film layer. - View Dependent Claims (20, 21)
