FIELD 0~ THE INVENTION
[0002] The present invention is directed to a lamp, and more particularly to a lamp including a light emitting diode (LED) as the lighting source. , ' 1p BACKGROUND
[0003] Lamps with an LED light source typically include a tamp cover, the LED, and a lamp holder. The LED is positioned inside the lamp cover and has two legs extending out of a head of the lamp cover through attached lead wires.
The lamp cover head is then put in a machine for injection, forming a lamp holder within which the lamp cover head and the lead wires are tightly enclosed. Producing a lamp in this manner is relatively difficult and complicated. Additionally, if the LED or the Tamp cover breaks, a professional tool is generally required to split open the lamp holder and to replace the broken part. The lamp holder must then be injected again.

Departing from the central position of the lamp seat 31 in a longitudinal direction is a positioning flange 312. The interior of the lamp seat 31 includes a cylindrical body having two or more openings through holes 314 extending longitudinally through the lamp seat 31.
(OOZO] A plastic-sealed portion of the LED 2 is positioned inside the lamp cover 1 with the base of the LED seating against the top surface of the cylindrical body 313. The LED legs 21 extend out of the lamp cover 1 into and through respective through holes 314.

The internal space of the permanent portion 321 includes an insulation projection 3211 that separates the interior of the permanent portion 321 into two longitudinal channels 323. Each of the two longitudinal channels 323 of the permanent portion 321 is in communication with a respective opening or through hole 314 in the lamp seat 31. The internal space of the movable portion 322 is recessed with a groove 3221 for receiving the insulation projection 3211 of the permanent portion 321.
[0022) A directive block 3212 having an angle of inclination is provided at the upper end of each of the longitudinal channels 323 of the permanent' portion 321 for shaping the space adjacent to the LED 2 into a narrow slot 3213.

Securing the lead wires 4 in the longitudinal channels 323 in this manner provides a secure' engagement between the conductive plates 41 of the lead wires 4 and the LED legs 21.
[0025] A groove 324 is formed in the outer wall surface of the inner cover 32, and a convex fitange is formed at the same position of the inner wall surface of the outer cover 33 for engagement with the groove 324. Combining the groove 324 with the convex flange enables the outer cover 33 to firmly enclose the inner cover with its top edge bearing against the positioning flange 312 of the Lamp seat 31.
[0026 One method of assembling the LED lamp includes positioning the conductive plates 41 of the lead wires 4 into the narrow slots 3213, -and fitting the positioning pin 3214 into the positioning hole 3223 to form the inner cover 32 (which includes the permanent portion 321 and the movable portion 322).

If an LED is broken or otherwise inoperable, a repair can be made by pulling the lamp .cover out of the ring-shaped groove, and pulling the bad LED from the lamp seat and replacing it with a new LED. If a conductive plate has a failure contact with the LED leg, a repair can be made by pulling the inner cover out of the outer cover, and removing the rnovable part. All of this repair work can be conveniently performed without damaging any section of the LED tamp.
~0028~ Thus, while, several embodiments have been shown and described, various changes and substitutions may of course be made, without departing from the spirit and scope of the invention. Many of the method steps described herein, for example, may be pertormed in a different order than that which is specifically described.
