Abstract

A light apparatus with an enlightened pattern includes a driver circuit, a LED plate, an optical light guide, a connector and a bulb shell. The LED plate connected to the driver circuit has a LED module for emitting a light. The optical light guide has a bottom end facing to the LED module for receiving the light and has a top end forming an enlightened pattern where the light escaped from the top end of the optical light guide. The connector is used for fixing the LED plate to the optical light guide for aligning the LED module to emit the light into the bottom end and for transmitting heat of the LED plate to the optical light guide.

Dependent claims

A light apparatus, comprising:

a driver circuit for converting an external power source to a driving current;
an LED plate being connected to the driver circuit and having a first LED module and a second LED module, the first light emitting a first light with the driving current;
an optical light guide, as a first optical unit, having a bottom end facing to the first LED module for receiving the first light and having a top end forming an enlightened pattern where the first light escaped from the top end of the optical light guide;
a second optical unit for guiding a second light emitted from the second LED module to a lateral surface of the optical light guide, the lateral surface being between the top end and the bottom end of the optical light guide;
a connector for fixing the LED plate to the optical light guide for aligning the first LED module to emit the first light into the bottom end and for transmitting heat of the LED plate to the optical light guide;
and
a bulb shell covering the optical light guide.
