Abstract

An LED lamp comprises a lamp enclosure and an LED assembly. The lamp enclosure defines a receiving hole therein, and the LED assembly is received in the lamp enclosure. The lamp enclosure is made of a light penetrable material. A plurality of fluorescent powders are doped integrally and distributed uniformly in the lamp enclosure. The LED assembly comprises a plurality of LEDs. Lights emitted by the LEDs pass through the lamp enclosure for lightening an outside of the LED lamp. A method for manufacturing the lamp is also disclosed.

Claims

1. An LED lamp, comprising:

a lamp enclosure defining a receiving hole therein and being made of a light penetrable material, a plurality of fluorescent powders being integrally doped in the lamp disclosure and distributed uniformly in the lamp enclosure;

an LED assembly being received in the receiving hole of the lamp enclosure, the LED assembly comprising a plurality of LEDs, lights emitted by the LEDs passing through the lamp enclosure for lightening an outside of the LED lamp.

2. The LED lamp of claim 1, wherein the fluorescent powders are mixed in the light penetrable material when the light penetrable material is at a molten state, and integrally formed in the lamp enclosure.

3. The LED lamp of claim 1, wherein the LEDs are blue LEDs for generating blue light, and the fluorescent powders are yellow fluorescent powders for generating yellow light when incited.

4. The LED lamp of claim 1, wherein the LED assembly includes a substrate located adjacent to a bottom side of the lamp enclosure, so that the lamp enclosure forms a wide upper chamber above the substrate and a narrow lower chamber below the substrate, and the LEDs are located on the substrate and protrude into the upper chamber of the lamp enclosure.

5. The LED lamp of claim 1, wherein the lamp enclosure is elongated and cylindrical.

6. The LED lamp of claim 5, further comprising a PCB received in the receiving hole and a power plug mounted to one end of the lamp enclosure, the power plug being in electrical connection with the PCB and the PCB being in electrical connection with the LED assembly.

7. The LED lamp of claim 5, wherein the lamp enclosure has a uniform thickness.

8. A method of manufacturing an LED lamp, the method comprising:

melting a light penetrable material;

mixing a plurality of fluorescent powders uniformly in the melted light penetrable material to form a mixture;

using said mixture to form a lamp enclosure which defines a receiving hole therein;

disposing an LED assembly which includes a plurality of LEDs into the receiving hole of the lamp enclosure.

9. The method as claimed in claim 8, wherein the lamp enclosure is elongated and cylindrical, and has a uniform thickness.

10. The method as claimed in claim 8, wherein the fluorescent powders are yellow fluorescent powders which generate yellow light when incited, and the LEDs are blue LEDs which generate blue light when powered.
