Abstract

An LED lamp assembly includes a lamp holder, which has a hollow light-transmittable shade that defines an inside chamber and a bottom opening at the bottom side of the inside chamber and a hollow base connected to the bottom side of the shade, and a light-emitting board, which has a resistor, LEDs and two contact members installed in a circuit board thereof and electrically connected to the circuit pattern of the circuit board and mounted with the circuit board inside the hollow base with the LEDs aimed at the inside chamber of the shade of the lamp holder.

Claims

1. An LED lamp assembly comprising:

a lamp holder having a light-transmittable shade and a base at a bottom side of said shade, said shade having an inside chamber and a bottom opening at the bottom side thereof in communication with the inside chamber, said base having an inside chamber in communication with the bottom opening and the inside chamber of said shade; and

a light-emitting board mounted in the inside chamber of said lamp holder, said light-emitting board having a circuit board, a resistor installed in said circuit board, at least one light emitting diode installed in said circuit board and electrically connected to said resistor, and two contact members installed in said circuit board and electrically connected to said resistor and said light emitting diode for electric connection to an external electricity.

2. The LED lamp assembly as claimed in claim 1, wherein said lamp holder is molded from electrically insulative plastics.

3. The LED lamp assembly as claimed in claim 1, wherein said lamp holder is molded from polycarbonate.

4. The LED lamp assembly as claimed in claim 1, wherein said lamp holder further comprises a coupler disposed on shade for fastening said lamp holder to an external object.

5. The LED lamp assembly as claimed in claim 4, wherein said coupler comprises two mounting members provided at two opposite sides of a periphery of said shade, each said mounting member comprising a stop block extending from the periphery of said shade and an engagement strip extending downwards from one lateral side of said stop block.

6. The LED lamp assembly as claimed in claim 1, wherein said base of said lamp holder comprises two mounting holes vertically extending through a top wall thereof;

wherein the contact members of said light-emitting board are exposed through said two mounting holes to the outside of said lamp holder.

7. The LED lamp assembly as claimed in claim 6, wherein said base of said lamp holder further comprises an insertion hole horizontally extending through a periphery and a part of the top wall thereof in communication with said mounting holes for the insertion of said light-emitting board into said lamp holder.

8. The LED lamp assembly as claimed in claim 1, wherein said base of said lamp holder further comprises an insertion hole in communication with the inside chamber of said base for the insertion of said light-emitting board into said lamp holder.

9. The LED lamp assembly as claimed in claim 1, wherein said circuit board of said light-emitting board comprises a circuit pattern at a top wall thereof;

said contact members of said light-emitting board are installed in the top wall of said circuit board near two distal ends and electrically connected to said circuit pattern;

said light emitting diode is installed in the top wall of said circuit board and electrically connected to said circuit pattern and aimed at the inside chamber of said shade of said lamp holder;

said resistor is installed in said circuit board and electrically connected to said circuit pattern.

10. The LED lamp assembly as claimed in claim 9, wherein said contact members are formed of tin paste.
