Abstract
A wide-angle illumination light-emitting diode (LED) light bulb includes a light base formed of a heat dissipation module having an end to which a circuit board is mounted. The circuit board carries at least one LED that is mounted to the circuit board in a chip-on-board fashion. A global cover is arranged above and covers the LED of the light base heat dissipation module. Intense white light generated by the LED is allowed to emit from the global cover with a wide angle of illumination similar to a conventional light bulb thereby realizing wide and uniform illumination.
Claims2
A wide-angle illumination light-emitting diode (LED) light bulb, comprising:
- a light base heat dissipation module having an end to which a circuit board is mounted, the circuit board carrying at least one LED that is mounted to the circuit board in a chip-on-board fashion;
- and
- a global cover arranged above and covering the LED of the light base heat dissipation module, whereby intense white light generated by a high-power LED is allowed to emit from the global cover with a wide angle of illumination.
