Abstract

An LED lamp includes a housing, at least one circuit board, several LED and two electric wires. The LED are mounted on a bottom face of the circuit board. The circuit board and the LED are all installed in the housing with the LED located at a bottom end of the housing. Two through holes are formed on a top end of the housing. The electric wires respectively passed through the through holes of the housing to electrically connect with the circuit board. The LED lamp is inbuilt with LED so that it is unnecessary to further install any LED bulb. The electric wires can be serially connected so that multiple LED lamps can be easily connected.

Claims

1. An LED lamp comprising:

a housing having a bottom end which is an open end, the housing being hollow, having a lower chamber and an upper chamber communicating with each other, the lower chamber being located at the bottom end of the housing, while the upper chamber being closer to a top end of the housing;

at least one locating section being formed on inner wall face of the housing between the lower chamber and the upper chamber;

two through holes being formed on a top end of the housing, inner ends of the through holes respectively communicating with the upper chamber;

at least one circuit board;

several LEDs mounted on a bottom face of the circuit board and several electronic elements electrically connected with the circuit of the circuit board;

the circuit board together with the LEDs and the electronic elements being installed in the housing, the circuit board being positioned in the locating section, the LEDs being located in the lower chamber, while the electronic elements being located in the upper chamber; and

two electric wires respectively passed through the through holes of the housing, inner ends of the electric wires extending into the upper chamber to connect with the circuit board, outer ends of the electric wires extending out of the housing.

2. The LED lamp as claimed in claim 1, wherein an upper locating section and a lower locating section are formed on inner wall face of the housing;

a lower circuit board and an upper circuit board being horizontally parallelly arranged and electrically connected with each other, the lower circuit board being positioned in the lower locating section near the lower chamber, while the upper circuit board being located in the upper locating section near the upper chamber;

the LEDs being mounted on a bottom face of the lower circuit board, while the electronic elements being mounted on a top face of the upper circuit board.

3. The LED lamp as claimed in claim 2, wherein the inner ends of the electric wires are connected to the upper circuit board.

4. The LED lamp as claimed in claim 2, wherein the two circuit boards are separated from each other by an insulating board.

5. The LED lamp as claimed in claim 4, wherein a third locating section is formed on the inner wall face of the housing between the two locating sections;

the insulating board is positioned in the third locating section.

6. The LED lamp as claimed in claim 1, further comprising a lens mounted at a bottom end of the housing.

7. The LED lamp as claimed in claim 2, further comprising a lens mounted at a bottom end of the housing.

8. The LED lamp as claimed in claim 1, wherein an outer circumference of the housing is formed with a thread.

9. The LED lamp as claimed in claim 1, further comprising a connecting member mounted on an outer circumference of the housing.
