摘要

A light bulb with LED symbols includes a light bulb shell, at least one LED light source, a driver, and an electrical connector. The LED light source includes electrodes and at least one LED substrate with LED chips mounted thereon. The LED substrate has a shape of a pattern, letter, word, logo, character or sign. The LED light source is housed inside a vacuum sealed chamber. The electrodes are connected to a pair of electrical wires, which are connected to a driver and an electrical connector. A method of manufacturing the light bulb is also disclosed.

主权项

1. A light bulb with LED symbols, the light bulb comprising:
a light bulb shell; a core column with an exhaust tube and a bracket; at least one LED light source; a driver; and an electrical connector, wherein the LED light source comprises at least one LED substrate with a plurality of LED chips mounted thereon, the at least one LED substrate having a shape of a pattern, letter, word, logo, character or sign, wherein the LED light source comprises first and second electrodes, wherein the LED light bulb shell is vacuum sealed with the core column so as to form a vacuum sealed chamber, which is filled with a gas having a low coefficient of viscosity and a high coefficient of thermal conductivity, wherein the bracket and the LED light source fixed thereon are housed in the vacuum sealed chamber, and wherein the LED light source is electrically connected to the driver via a pair of electrical wires, the driver being connected to the electrical connector, and the electrical connector being electrically connected to an external power supply so as to light the LED light source.
