A lamp includes a supporting body and a lamp body. The supporting body is fixed to a support such as a ceiling. The supporting body defines a plurality of apertures each including a hole and a slot. The slot has a width less than a diameter of the hole. The lamp body includes a housing, a heat sink, a light source and a cover. The housing forms a plurality of protrusions each including a pole and a head. The head has a diameter larger than a width of the slot. The protrusions extend through the holes of the apertures and then are rotated into the slots, whereby the heads are located above the slots and engage with the supporting body. Thus, the lamp is suspended from the support. A resilient member is provided between the housing and the supporting body.

LED illumination device

An LED bulb includes a connector for electrically connecting with a power supply, a heat sink disposed on the connector, an LED module mounted the heat sink, and an envelope secured to the heat sink and covering the LED module. The heat sink includes a tubular body, a plurality of first fins extending outwardly from an outer circumference of the tubular body, and a plurality of second fins extending inwardly from an inner circumference of the tubular body.

LED bulb

An LED bulb includes a connector, a heat sink disposed on the connector, an LED module, and an envelope secured to the heat sink and covering the LED module. The heat sink includes a tubular body defining a central through hole, a plurality of fins, and a supporting body located in the tubular body and interconnecting inner edges of the fins. The LED module is attached on the supporting body of the heat sink. A fan is received in the tubular body. When the LED bulb is at work, the fan generates an airflow which flows from an outer environment through the tubular body, the through hole, the LED module, the fins and finally the tubular body to return to the outer environment, thereby to effectively take away the heat generated by the LED module.

An LED lamp includes a light source including LEDs and a heat dissipation device. The heat dissipation device includes a heat absorption board contacting the light source to absorb heat generated by the LEDs, a fin assembly located over the heat absorption board, two heat pipes thermally connecting the heat absorption board and the fin assembly, a fan and a fan holder fixing the fan on the fin assembly. The fan holder includes a supporting board supporting the fan and supporting posts connecting an outer edge of the heat dissipation board and an outer edge of the supporting board. The supporting posts are embedded in the fin assembly.

A heat dissipation device includes a heat absorption board adapted for contacting a light source to absorb heat therefrom, a fin assembly located over the heat absorption board, two spaced heat pipes each comprising an evaporator section and two condenser sections extending from two opposite ends of the evaporator section, and a heat sink located between the heat absorption board and the fin assembly. The condenser sections extend through the fin assembly. The evaporator sections of the heat pipes are sandwiched between the heat sink and the heat absorption board. The heat sink includes alternate first and second heat dissipating branches extending outwardly from a central portion thereof. The first heat dissipating branches contact the evaporator sections of the heat pipes. The second heat dissipating branches are located between the heat pipes.

An LED lamp includes a heat sink, a plurality of LED modules and a reflector. The heat sink has a conical wall. The LED modules are attached to an inner surface of the wall. The reflector is engaged in the heat sink. The reflector has an outer surface facing and angled with the LED modules. Light generated by the LED modules is reflected by the outer surface of the reflector to radiate out of the LED lamp.

LED lamp

A hanging LED lamp includes a base, a heat sink attached to a bottom of the base, a plurality of heat conducting plates coupled to a periphery of the heat sink and connecting with the base and the heat sink, a plurality of LED modules mounted on the heat conducting plates, a cover engaging the base and covering the heat sink, the heat conducting plates and the LED modules therein, and a fixing member connecting a top of the base to fix the LED lamp in a desired position. A plurality of heat pipes are embedded in the heat conducting plates with first ends connecting with the heat sink and second ends connecting with the base.

An LED lamp includes a base, a heat sink mounted on the base, a plurality of LED modules attached to a circumference of the heat sink, a plurality of reflecting rings enclosing the heat sink and surrounding the LED modules and a heat dissipating member mounted on a top of the heat sink and making thermally conductive contact with the heat sink.
