Abstract

A LED lamp comprises: a lamp base; an illuminating component, mounted on the lamp base, wherein the illuminating component comprises a circuit board and a plurality of LEDs arranged on the circuit board; a lamp shade, mounted on the lamp shade for enclosing the illuminating element, wherein the lamp shade has at least one open area; and at least one waterproof and ventilative element, disposed on the open area for covering the open area; thereby, vapors inside the lamp shade can vacate out of the LED lamp through the waterproof and ventilative element, while external vapors cannot infiltrate into the lamp shade through the waterproof and ventilative element.

Claims

1. A LED lamp, comprising:

a lamp base;

an illuminating component, mounted on the lamp base, wherein the illuminating component comprises a circuit board and a plurality of LEDs arranged on the circuit board;

a lamp shade, mounted on the lamp base and enclosing the illuminating element, wherein the lamp shade has an open area; and

a waterproof and ventilative element, disposed on the open area for covering the open area;

thereby, vapors inside the lamp shade vacate out of the LED lamp through the waterproof and ventilative element, external vapors fail to infiltrate into the lamp shade through the waterproof and ventilative element.

2. The LED lamp of claim 1, wherein the lamp base has two electrically conductive sockets respectively at two opposite terminals of the lamp base, the lamp shade is a hollow tube, two opposite ends of the lamp shade are respectively connected to the two electrically conductive sockets, and the circuit board of the illuminating component is electrically connected to the two electrically conductive sockets.

3. The LED lamp of claim 1, wherein the lamp shade has two fixtures being extended from an inner wall of the lamp shade, and the circuit board being attached to the two fixtures and the interior of the lamp shade.

4. The LED lamp of claim 1, wherein the waterproof and ventilative element is made of waterproof and ventilative fabric.

5. The LED lamp of claim 4, wherein the waterproof and ventilative element is made of polytetrafluoethylene foam.

6. The LED lamp of claim 1, wherein the open area is a through hole.

7. A LED lamp, comprising:

a lamp base;

an illuminating component, mounted on the lamp base, wherein the illuminating component comprises a circuit board and a plurality of LEDs arranged on the circuit board;

a lamp shade, mounted on the lamp base and enclosing the illuminating element, wherein the lamp shade has a plurality of open areas; and

a plurality of waterproof and ventilative elements, respectively disposed on the open areas for covering those open areas;

thereby, vapors inside the lamp shade vacate out of the LED lamp through the waterproof and ventilative elements, external vapors fail to infiltrate into the lamp shade through the waterproof and ventilative elements.

8. The LED lamp of claim 7, wherein the lamp base has two electrically conductive sockets respectively at two opposite terminals of the lamp base, the lamp shade is a hollow tube, two opposite ends of the lamp shade are respectively connected to the two electrically conductive sockets, and the circuit board of the illuminating component is electrically connected to the two electrically conductive sockets.

9. The LED lamp of claim 7, wherein the lamp shade has two fixtures being extended from an inner wall of the lamp shade, and the circuit board being attached to the two fixtures and the interior wall of the lamp shade.

10. The LED lamp of claim 7, wherein the waterproof and ventilative elements are made of waterproof ventilative fabric.

11. The LED lamp of claim 10, wherein the waterproof and ventilative elements are made of polytetrafluoethylene foam.

12. The LED lamp of claim 7, wherein the open areas are through holes.
