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.

LED package

An LED bulb includes a connector for electrically connecting with a power supply, a heat sink disposed on the connector, and a plurality of LEDs mounted the heat sink. 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 LEDs are attached on a second face of the base. The base defines a plurality of through tunnels extending through the base from the first face to the second face of the base.

LED bulb

A method for manufacturing an LED module, including steps of: providing a heat conductive plate and an LED die, the heat conductive plate defining a concave groove therein; forming an electrode circuit layer on the heat conductive plate around the concave groove; plating one metal layer on a bottom of the concave groove of the heat conductive plate, and plating another metal layer on the LED die; eutectically bonding the metal layer of the heat conducting plate and the metal layer of the LED die together to form into an eutectic layer; forming electrodes on the LED die, and connecting the electrodes with the electrode circuit layer; and encapsulating the LED die in the concave groove.

Method of manufacturing LED module

A light source holder includes a spherical surface and a number of recessed portions. The recessed portions are defined in the spherical surface and arranged substantially evenly over the spherical surface. Each of the recessed portions comprises a plurality of inner surfaces. The inner surface of each recessed portion comprises a bottom surface and a lateral reflective surface. The bottom surface is capable of having a solid-state light source arranged thereon. The lateral reflective surface is adjacent to the bottom surface and configured for reflecting light emitted from the solid-state light source and outputting the light from the recessed portion.

Illumination device

An LED lamp for lighting purpose includes a lamp base, a heat sink, a plurality of LED modules and a blower. The lamp base encloses an inner space and defines a plurality of vents therein. The vents communicate the inner space with a surrounding atmosphere. The heat sink comprises a cylinder at a center thereof. The cylinder has a through hole therein, which communicates with the inner space and vents of the lamp base and cooperates therewith to form an air passage. The LED modules are attached to a periphery of the heat sink. The blower generates an airflow circulating through the air passage to thereby dissipate heat generated by the LED modules.
