Abstract: An LED illuminating device includes a boiling room, an optical module, a heat insulating member and a heat exchanging member communicating with the boiling room. The boiling room defines a horizontal room and an annular, vertical room having a bottom end surrounding the horizontal room. A wick structure is received in the boiling room. Working fluid is received in the boiling room and saturated in a bottom portion of the wick structure. The optical module includes a plurality of LEDs attached to a heat absorbing member connecting with the bottom portion of the wick structure. The heat insulating member is received in the boiling room and attached to a middle portion of the wick structure for thermally insulating the middle portion of the wick structure from vaporized working fluid in the horizontal room of the boiling room.

Abstract: An LED lamp includes a light-emitting module, an electrical module and an elongated heat dissipating member. The light-emitting module includes a light source provided with a plurality of LEDs. The electrical module includes a circuit board electrically connected with the LEDs of the light source and two end caps each forming a pair of electrical pins at an outer end thereof. The heat dissipating member is arranged between and connecting with the two end caps, the heat dissipating member is a hollow metal tube and includes a mounting portion and a heat dissipating plate extending from the mounting portion. The mounting portion and the heat dissipating plate cooperatively define an elongate chamber. The circuit board is accommodated in the chamber of the heat dissipating member. The light source is thermally attached to an outer surface of the mounting portion.

Abstract: An LED lamp includes a cooling member, a light source, a lamp cover and a pair of lamp caps arranged at opposite ends of the cooling member. The cooling member has an elongated heat absorbing plate forming a heat absorbing surface at one outer side thereof. The light source includes a plurality of LEDs arranged on the heat absorbing surface. The lamp cover covers the LEDs therein and engages with the cooling member. Each lamp cap includes an end cap fixed on the cooling member and a connector rotatably connected with the end cap. The connector includes a pair of poles being electrically connected to the LEDs and extending outwardly therefrom for inserting into a lamp holder to get a power for the LEDs.
