LED and LED lamp
First Claim
1. An LED lamp including at least one LED, comprising:
- a heat sink;
at least one LED mechanically connected to the heat sink through screws or screw holes on or in a base bottom of the LED;
a driving circuit including an electrical connector, to which outgoing leads of the LEDs are connected; and
a transparent bulb housing mounted over the LED;
wherein the LED includes at least one LED chip directly mounted on a base of high heat connectivity;
wherein the LED chip is electrically connected to an applied power supply through a circuit board and the LED chip has a transparent medium layer disposed thereon;
wherein a base top surface is a light reflective surface or a light reflective surface is disposed around the base;
wherein the circuit board is disposed on the base; and
wherein the base is a metal base and a screw mechanically connects the heat sink to a bottom surface of the metal base.

Abstract
This invention relates to a light emitting diode (LED) and a LED lamp consisted of LEDs. The LED comprises at least one LED chip. The LED is mounted on a high heat conductivity base and is connected to an applied power supply through a circuit board. The LED chip also has a transparent medium layer on it. The base top surface acts as a light reflective surface, or a light reflective surface is provided around the base, the LED comprises a screw extended downwards from the base bottom or a screw hole in the base bottom to connect the LED to a heat sink mechanically. The LED is electrically connected to a driving circuit through its outgoing wires. The driving circuit is in turn electrically connected to an electrical connector through its housing. A LED lamp can be fabricated after the LED is enclosed in a transparent bulb housing. The LED has high efficiency, high power and long lifetime and can be used to fabricate LED traffic lamps, LED plane light sources, etc.
