4. lighting device as claimed in claim 3, it is characterized in that: each end plug is to be formed with an annular groove on its horizontal-extending inner surface partly, this lighting device also comprises a columned transparent light guide bar, the two ends of this leaded light bar partly are respectively to be formed with an outward extending annular lip, and each flange is to be inserted in the annular groove of end plug of a correspondence so that this leaded light bar is arranged in this shell and so that each LED wafer is to be positioned at one by within an annular lip formed space of end face corresponding with of this leaded light bar.
5. lighting device as claimed in claim 4 is characterized in that: this leaded light bar is to be formed with several bubbles so that the light that penetrates from LED wafer is to change direction to leave this shell when running into bubble after entering the leaded light bar in inside.
6. lighting device as claimed in claim 1 is characterized in that: this enclosure is to be injected into inert gas.
7. lighting device as claimed in claim 1 is characterized in that: this enclosure is to be injected into liquid dye or fluorescent agent.
8. lighting device as claimed in claim 1 is characterized in that: this enclosure is to fill with optical fiber, one of them end of every optical fiber be provided with fluorescent material in order to light emission to housing exterior.
9. lighting device as claimed in claim 1, it is characterized in that: this light emission unit also comprises two reflection shields, and this each reflection shield is to be located on this each installation base plate so that this each LED wafer is to be positioned at the central part of this reflection shield to reach reflective effect.
