An LED bulb includes a heat sink, a circuit, an LED, and a driving module. The heat sink includes a base, a tube extending downwardly from a first face of the base, and a plurality of fins extending outwardly from an outer circumference of the tube. The circuit is formed on a second face of the base, and the LED is disposed on the second face of the base and electrically connected with the circuit. The LED bulb further includes a first lead and a second lead electrically connecting with the circuit and extending through the base. The driving module includes a first electrode, and a second electrode electrically insulated from the first electrode and surrounding the first electrode. The first electrode of the driving circuit contacts with the first lead, and the second electrode of the driving circuit contacts with the second lead.

LED bulb and method for manufacturing the same

A LED package includes a substrate, at least one LED chip, a transparent adhesive and a lens. The at least one LED chip is mounted on the substrate. The transparent adhesive is filled between the LED chip and the lens. A number of through holes is regularly defined in an optical non-effective portion of the lens. The through holes are configured for increasing the air convection between inside and outside of the lens.
