A light passing tube with a main portion, a first end portion and a second end portion. The first end portion and the second end portion are placed at two opposite ends of the main portion. A first end cap is attached to the first end portion and a second end cap is attached to a second end portion of the light passing tube. An exterior surface of the main portion has defined a peripheral edge line. The first end portion has a tilt curve portion with a tilt angle between the peripheral edge line and an exterior surface of the first end portion. ## Claims ### Claim 1 An LED light tube, comprising: an LED strip having a substrate plate and multiple LED modules, the multiple LED modules being mounted on the substrate plate; a light passing tube, having a main portion, a first end portion and a second end portion, the first end portion and the second end portion being placed at two opposite ends of the main portion, the light passing tube being used for storing the LED strip; a first end cap attached to the first end portion of the light passing tube, an exterior surface of the main portion defining a peripheral edge line, the first end portion having a tilt curve portion with a tilt angle between the peripheral edge line and an exterior surface of the first end portion, the tilt angle being between three degrees to ten degrees; a second end cap attached to a second end portion of the light passing tube, the first end cap and the second end cap each having two pins; and a driver enclosing in one of the end caps for supplying a driving current to the multiple LED modules and for controlling the multiple LED modules, wherein the first end cap has an extended electrode for connecting to an attached device for providing an external power to the attached device, wherein the attached device is detachable from the first end cap to be replaced with an another attached device, the another attached device provides a different function as the attached device. ### Claim 2 (depends on 1) The LED light tube of claim 1, wherein the tilt curve portion has a low section and a high section, the low section is adjacent to the main portion of the light passing tube, the high section is adjacent to the first end cap, a slope rate of the low section is smaller than the high section. ### Claim 3 (depends on 1) The LED light tube of claim 1, wherein the tilt curve portion has a first part connected to the first end cap, a middle part and a second part connected to the main portion of the light passing tube, the first part and the second part have larger diameters than the middle part. ### Claim 4 (depends on 3) The LED light tube of claim 3, wherein the tilt curve portion has a first part connected to the first end cap, a middle part and a second part connected to the main portion of the light passing tube, the first part and the second part have smaller diameters than the middle part. ### Claim 5 (depends on 3) The LED light tube of claim 3, wherein the tilt curve portion has a first part connected to the first end cap, a middle part and a second part connected to the main portion of the light passing tube, diameters of the first part, the middle part and the second part are changed gradually. ### Claim 6 (depends on 1) The LED light tube of claim 1, wherein the another attached device and the attached device are operated under different wireless protocols. ### Claim 7 (depends on 1) The LED light tube of claim 1, wherein the attached device has a sensor for collecting an environment information outside the LED light tube, the driver operates according to the environment information. ### Claim 8 (depends on 7) The LED light tube of claim 7, wherein the sensor detects an ambient light level, the driver adjusts an output light of the LED strip according to the ambient light level. ### Claim 9 (depends on 7) The LED light tube of claim 7, wherein the sensor detects a movement of an object, and the driver controls the light strip based on whether the movement exists. ### Claim 10 (depends on 1) The LED light tube of claim 1, wherein the attached device has a battery providing a battery power to the driver to drive the LED strip. ### Claim 11 (depends on 10) The LED light tube of claim 10, wherein the battery provides the driver to drive the LED strip to emit light when the LED light tube apparatus is removed from a normal bracket holder. ### Claim 12 (depends on 10) The LED light tube of claim 10, wherein an output light level of the LED strip is determined by an expected use time period. ### Claim 13 (depends on 1) The LED light tube of claim 1, wherein the attached device has a rotating ring wrapping the LED light tube apparatus, and rotatable manually relative to the LED light tube. ### Claim 14 (depends on 13) The LED light tube of claim 13, wherein a rotation angle of the rotating ring is provided to the driver to determine how to control the LED strip. ### Claim 15 (depends on 14) The LED light tube of claim 14, wherein the multiple LED modules of the LED strip has a first set and a second set of LED modules with different optical characteristics, the driver adjusts a relative driving current ratio to the first set of the multiple LED modules and the second set of the multiple LED modules to generate mixed output lights of different optical characteristics. ### Claim 16 (depends on 13) The LED light tube of claim 13, wherein the LED strip emits a light beam with a main direction, a rotating angle of the rotating ring controls the driver to change the main direction of the light beam. ### Claim 17 (depends on 16) The LED light tube of claim 16, wherein the rotating ring moves the LED strip to change the main direction of the light beam. ### Claim 18 (depends on 1) The LED light tube of claim 1, wherein the attached device uses a magnet unit to attach to the first end cap.
