Abstract

A lighting apparatus includes a bottom housing, a light cover, multiple LED modules and a light source plate. The bottom housing includes a bottom plate. The bottom plate has a first film layer and a substrate layer. The first film layer has a width between 2 μm and 120 μm. The light source plate is mounted with the multiple LED modules on a top side of the light source plate. A bottom side of the light source plate faces to the bottom plate and the top side of the light source plate faces to the light cover. A light of the multiple LED modules pass through the light cover.

First claim

1 . A lighting apparatus, comprising:
a bottom housing, wherein the bottom housing comprises a bottom plate, wherein the bottom plate has a first film layer and a substrate layer, wherein the first film layer has a width between 2 μm and 120 μm; a light cover; multiple LED modules; and a light source plate mounted with the multiple LED modules on a top side of the light source plate, wherein a bottom side of the light source plate faces to the bottom plate and the top side of the light source plate faces to the light cover, wherein a light of the multiple LED modules pass through the light cover.

2 . The lighting apparatus of claim 1 , wherein the bottom plate further has a second film layer, wherein the first film layer and the second film layer are attached on two sides of the substrate layer.

3 . The lighting apparatus of claim 2 , wherein there is a first glue layer between the first film layer and the substrate layer, wherein there is a second glue layer between the second film layer and the substrate layer.

4 . The lighting apparatus of claim 3 , wherein the substrate layer has a metal layer.

5 . The lighting apparatus of claim 4 , wherein substrate layer also has a wiring layer with contact nodes for guiding electrical signal through the wiring layer.

6 . The lighting apparatus of claim 4 , wherein an first antenna layer is attached to the bottom housing.

7 . The lighting apparatus of claim 6 , wherein the first antenna layer is between the substrate layer and the first film layer, wherein there is a second antenna layer attached between the substrate layer and the second film layer, wherein the first antenna layer and the second layer receive wireless commands from an external device, wherein a controller decodes the wireless command and adjusts driving currents to the multiple LED modules to obtain a required light parameter.

8 . The lighting apparatus of claim 4 , wherein there is a thermal passing unit for guiding heat of the multiple LED modules to the bottom housing.

9 . The lighting apparatus of claim 8 , wherein a portion of the first film for contacting the thermal passing unit is removed for the thermal passing unit directly contact the substrate layer without passing heat via the first film to the substrate layer.

10 . The lighting apparatus of claim 3 , wherein the first glue layer covers 60% to 95% of an interface area between the first film layer and the substrate layer.

11 . The lighting apparatus of claim 2 , wherein there are protective layers on the first film layer and the second film layer.

12 . The lighting apparatus of claim 2 , wherein the first film layer has a first thickness, the second film layer has a second thickness, wherein the first thickness is smaller than the second thickness for 5% of the second thickness.

13 . The lighting apparatus of claim 2 , wherein the first film layer has a first thickness, the second film layer has a second thickness, wherein the second thickness is smaller than the first thickness for 5% of the first thickness.

14 . The lighting apparatus of claim 2 , wherein the first film layer and the second film layer are plastic layers.

15 . The lighting apparatus of claim 14 , wherein the plastic layers are made of PE or PP material.

16 . The lighting apparatus of claim 1 , wherein the bottom housing has two lateral wall, wherein the bottom plate is a rectangular shape.

17 . The lighting apparatus of claim 16 , wherein there are two side covers disposed on two opposite ends of the bottom housing.

18 . The lighting apparatus of claim 17 , wherein there is a wiring layer for passing electric signal from one cover to the other cover for connecting another lighting apparatus, wherein said another lighting apparatus and the lighting apparatus are connected in parallel.

19 . The lighting apparatus of claim 16 , wherein there are multiple cutting segment structures on the bottom housing for changing the bottom housing to fit different lengths.

20 . The lighting apparatus of claim 19 , wherein the cutting segment structures are provided to break off to change the length of the bottom housing.
