Abstract

An illuminating device mainly includes a tube-like lamp disposed in a main body. The tube-like lamp has two terminal portions adapted for electrically connecting to a power source and a bending portion between the terminal portions. The main body is provided with a support having two hooked portions configured to support the tube-like lamp. The present invention further provides another tube-like lamp characterized by having a buffer part securely attached on the bending portion for lessening or absorbing the shock of an impact on the tube-like lamp. The support may has a gap between the hooked portions such that the tube-like lamp fit with sufficient tightness into the gap between the hooked portions thereby immobilizing the tube-like lamp more efficiently and absorbing the shock.

Claims

1. A tube-like lamp having two terminal portions adapted for electrically connecting to a power source and a bending portion between the terminal portions, the tube-like lamp comprising a buffer part securely attached on the bending portion for lessening or absorbing the shock of an impact on the tube-like lamp.

2. The tube-like lamp as claimed in claim 1, wherein the buffer part is an O-ring.

3. The tube-like lamp as claimed in claim 1, wherein the buffer part is a C-shaped ring.

4. An illuminating device comprising:

a lamp having two terminal portions adapted for electrically connecting to a power source and a bending portion between the terminal portions, the lamp comprising a buffer part securely attached on the bending portion; and

a main body provided with a supporting device for connecting the buffer part of the lamp thereby helping to fasten the lamp to the main body.

5. The illuminating device as claimed in claim 4, wherein the support has two hooked portions and a gap between the hooked portions, the hooked portions are configured to support the lamp, and the buffer part of the lamp fits into the gap between the hooked portions.

6. The illuminating device as claimed in claim 4, wherein the buffer part is an O-ring.

7. The illuminating device as claimed in claim 4, wherein the buffer part is a C-shaped ring.

8. The illuminating device as claimed in claim 4, wherein the illuminating device is a backlight device for a liquid crystal display.

9. The illuminating device as claimed in claim 4, wherein the main body comprises:

a housing;

a reflector interposed between the lamp and the housing; and

a diffusion plate,

wherein the reflector reflects light radiated from the lamp toward the diffusion plate.

10. The illuminating device as claimed in claim 4, wherein the main body comprises:

a housing including a base and a case body;

a reflector interposed between the lamp and the base of the housing; and

a diffusion plate sealing the top of the case body of the housing,

wherein the terminal portions of the lamp are disposed along one side of the base.

11. An illuminating device comprising:

a first lamp having two terminal portions adapted for electrically connecting to a power source and a bending portion between the terminal portions; and

a main body provided with a first supporting device, the first supporting device having two hooked portions configured to support the first lamp thereby helping to fasten the lamp to the main body.

12. The illuminating device as claimed in claim 11, further comprising:

a second lamp having two terminal portions adapted for electrically connecting to a power source and a bending portion between the terminal portions;

a second supporting device disposed on the main body, the second supporting device having two hooked portions configured to support the second lamp; and

a third supporting device disposed on the main body and disposed between the first lamp and the second lamp, the third supporting device having two hooked portions configured to support the first lamp and the second lamp.

13. The illuminating device as claimed in claim 11, wherein the illuminating device is a backlight device for a liquid crystal display.

14. The illuminating device as claimed in claim 11, wherein the main body comprises:

a housing;

a reflector interposed between the lamp and the housing; and

a diffusion plate,

wherein the reflector reflects light radiated from the lamp toward the diffusion plate.

15. The illuminating device as claimed in claim 11, wherein the main body comprises:

a housing including a base and a case body mounted on the base;

a reflector interposed between the lamp and the base of the housing; and

a diffusion plate sealing the top of the case body of the housing,

wherein the terminal portions of the lamp are disposed along one side of the base.
