Vapor lamp assembly technique

摘要

An LED lamp that couples a heatsink with LEDs mounted on it to a glass envelope with a surface area equivalent to approximately that of a conventional light bulb, and by using a coolant vapor within the glass envelop, the lamp can be made much lighter and more cheaply. The heat generated by the LEDs is dissipated by the glass surface and not conducted into the heatsink. The heatsink can thus be mostly for the power supply. This allows for a reduced operating temperature for the power supply components that allows for a longer expected life for the power supply. In addition, the LED light bulb of the present invention can have nearly the same shape and appearance as a standard incandescent bulb. The invention can also have an advanced flyback power supply.

1. A method for assembling an Light Emitting Diode (LED) light bulb comprising: mounting LEDs onto a thermally conductive structure; mechanically incorporating the thermally conductive structure with a glass base; electrically connecting the LEDs with conductors incorporated within the glass base; fusing a glass envelope to the glass base via a heat source; injecting a coolant into the glass envelope via a tube; reducing the pressure within the glass envelope; and sealing off the tube.
