FIELD

The present invention relates to an energy-saving lighting fixture, in particular a LED lamps. Background technique

In the current global energy increasingly tense situation, countries are advocating energy saving, energy looking for ways in which LED (light emitting diode) because of its environmental protection, long life, low driving voltage, high luminous efficiency, no radiation, anti- shock, etc., has attracted attention.

On the market, various LED lamps have varying quality, there is insufficient brightness most, limited power, heat dissipation is poor, light attenuation and high cost problems.

In Patent Publication No. CN1407271A LED chip fluorescent lamps invention patent, will be embedded in the LED lamp housing wick column light emission by the driving power source drives the LED in the socket. Apparently the patent does not take into account the very good heat dissipation problem of the LED, alone circumferential cooling holes in the socket are still unable to meet the heat dissipation high power LED, the LED can use low-power type, high-power LED can not be employed, restriction and the use of the lamp brightness. SUMMARY

For the above-described disadvantages of the prior art, the present invention provides an LED lamps, a lamp, LED light source, the radiator, the insulating member and the base composition, wherein the shade using PC, acrylic, glass and other materials, internal coating with a phosphor layer, the shape may be of various shapes spherical, hemispherical, elliptical, honeycomb-shaped or shaped like a mushroom, and can arbitrarily change the size and specifications. Using high power LED LED light source as the light source, and its power may be varied according to the purpose, LED embedded in a surface such as table circular radiator end portion, wherein the surface is coated with a truncated cone-based reflective layer, and an LED embedded uniformly distributed grooves, scull bottom or both sides of the recess is provided with an opening. The middle radiator is a hollow cylinder in a uniform distribution around the metal fins, the horizontal distribution and the vertical distribution, or a distribution of inclination may be employed or a mixture of several insulating member using an insulating material PC, nylon and the like, which separate radiator and the base isolation, the radiating insulated. A housing comprising a base cap and an LED drive power, wherein the LED driving power supply mounted in the base housing, the LED connected through the cable groove-like surface of the rotary table opening, the power in the hollow cylinder and the base, a passage.

And a connector connected to the base and the insulating member are connected, the insulating member and the radiator covers and the radiator, according to the various needs of the environment and costs, can be used with a flip-chip type connection slot and the detent structure or an internal thread and screw structure or silicone adhesive or silicone adhesive and then press the male screw fixation and other otherwise connected.

The LED light source may be a separate die, chip scale packages, the package and the conventional surface mounted device (SMD), and other high-power LED.

The heat sink is integrally closed at one end by a truncated cone surface based composition and the heat sink, the surface is provided with a truncated cone-based reflective layer, the fins may be arranged in the horizontal profile, inclined or vertical distribution of one or several distribution mix body; annular shape may be circular, fan-shaped, square, polygonal, one or a mixture of several.

Fins on the heat sink may need to reconcile the number and size.

The class may be a truncated cone frustum-type surface, hemispherical, conical, cylindrical or prismatic one kind or a mixture of several.

Said base alloy, copper, aluminum and other metals and alloys may be employed.

The present invention preclude the radiator is integral with the structure, the LED light source can be efficiently generated through heat:: dissipated through the heat sink, to achieve good cooling effect, slow decay of the light, improving the use life of the LED.
