Abstract

A LED bulb apparatus includes a main body, a light source, two end covers, and two connectors. The main body is a hollow structure. The light source module is disposed inside the main body. The light source module has a base plate, a driver and a light source. The driver and the light source being are mounted on the base plate. The two end covers are fixed on two ends of the main body for closing the hollow structure for forming a closed container for storing the light source module and a heat dissipation gas.

First claim

The invention claimed is:

1. A LED bulb apparatus comprising:
a main body, being a hollow structure;
a light source module disposed inside the main body, the light source module comprising a base plate, a driver and a light source, the driver and the light source being mounted on the base plate;
two end covers fixed on two ends of the main body for closing the hollow structure for forming a closed container for storing the light source module and a heat dissipation gas; and
two connectors respectively having embedded portions partially embedded in the two end covers while exposed portions outside the end covers, wherein a fluorescent layer covers both the light source and the driver.

2. The LED bulb apparatus of claim 1 , wherein the main body is a R7 bulb standard shape.

3. The LED bulb apparatus of claim 1 , wherein the main body is made of glass.

4. The LED bulb apparatus of claim 3 , wherein the main body is a glass tube.

5. The LED bulb apparatus of claim 1 , wherein the driver comprises driver components mounted on the base plate.

6. The LED bulb apparatus of claim 5 , wherein the driver components comprise rectifier diodes disposed on at least one end of the base plate.

7. The LED bulb apparatus of claim 6 , wherein the rectifier diodes are both ends of the base plate.

8. The LED bulb apparatus of claim 1 , wherein the two end covers are made of a same glass material as the main body and are pressed to conceal the main body during manufacturing.

9. The LED bulb apparatus of claim 1 , further comprising two conductive wires on two ends of the base plate, the two conductive wire being partly embedded in the end cover and partly exposed outside the end cover for connecting to an external power source.

10. The LED bulb apparatus of claim 9 , wherein the conductive wires are Dumet wires.

11. The LED bulb apparatus of claim 1 , further comprising an exhaust tube for installing the heat dissipation gas while manufacturing and concealed after the heat dissipation gas being installed.

12. The LED bulb apparatus of claim 11 , wherein the exhaust tube is made of a same glass material as the main body.

13. The LED bulb apparatus of claim 1 , wherein the driver adjusts a driving current supplied to the light source module by reference to the operation temperature detected by the temperature sensor.

14. The LED bulb apparatus of claim 1 , wherein a heat dissipation material is mixed in the fluorescent layer.

15. The LED bulb apparatus of claim 14 , wherein the heat dissipation material is metal powder.

16. The LED bulb apparatus of claim 1 , wherein the two end covers are plastic piece attached to the main body with glue.

17. The LED bulb apparatus of claim 1 , wherein the two end covers have metal pins embedded in the two end covers for connecting the driver to an external power source.
