Described smooth conversion fluorescence module is large semi-spherical shape.

Described LED light source comprises circuit board and the LED being welded thereon, and circuit board is bonded on round table-like boss by heat conduction elargol.

Preferred version is that described LED is high-power blue-ray LED, or the combination of high-power blue-ray LED and high-power red-light LED.

Preferred version is that the bus of described round table-like boss and the angle of horizontal plane are 65 degree-75 degree.

In actual applications, in order to solve the problem of great power LED cooling difficulty, often adopt the mode that strengthens radiator surface area to reach thermal balance, but the weight increase that the consequence of doing is like this radiator causes too much consuming metal material, the utility model has been optimized structural design, lamp body is made by heat-conducting plastic and aluminum, lamp body inner chamber and round table-like boss are made up of aluminium, lamp body external cooling fin is made up of heat-conducting plastic, LED light source is directly fixed to boss top by heat conduction elargol, the passage of heat complete metal of LED like this, and utilize the feature of heat-conducting plastic excellent heat radiation performance, reach thermal balance with external environment.

High-power blue-ray LED or blue light+red-light LED mixes use, realizes the three-dimensional LED light source scheme of low cost, high colour developing, high light efficiency, luminous intensity distribution design more flexibly.Light conversion fluorescence module, away from LED chip, when realizing remote excitation, has solved the problem of the aging decay of fluorescent material.

The bus of round table-like boss and the angle of horizontal plane are 65 degree-75 degree, then buckle the light conversion fluorescence module of large semi-spherical shape, make LED light source part lighting angle increase to 270 degree left and right, meet the demand of various space illuminations and decoration.

The light conversion fluorescence module of large semi-spherical shape is that macromolecule resin is made by techniques such as cast, injection mouldings, includes light-converting material.The LED light fixture colour temperature making is in 2700K-6500K left and right, and colour rendering index can reach more than 90.
