Described rear end element is provided with port.

Described rear end element is provided be used to the storage silo of depositing power supply.

Described illumination module also comprises light source sealing device and glass lens, and described light source sealing device is located on the described light source, and described glass lens is located on the described light source sealing device.

The end cover of described radiator is provided with 3 described light sources.

The both sides of described radiator are provided with some curved metal bars.

The utility model has the advantage of that light fixture modularity concept is to come the different lighting unit of distributor according to different lighting demands, can select neatly, the watt level of combination lighting satisfies illumination, and adopted again the heat radiation technology of novel geometric form magneto-caloric material to guarantee the reliability and stability of high power light source work; The every unit of light source group has adopted the integrated multicore light source of a plurality of LED and supporting glass lens, and the steady illumination of 2700～6000K light is provided under the optical physics effect of the light source of different-colour and lens.Polarity can tactic characteristics under magnetic field environment according to magneto-caloric material again for light source radiation structure of the present utility model, utilization forms the thermal field air-flow of transverse shifting at device surface, can fully play the purpose action principle of dynamic heat radiation refrigeration, utilize again simultaneously unique " U " shape emitting structural to be arranged in the radiator of array, make magnetic field air-flow and cold air form active swap on a large scale, thereby reach the not only purpose of balanced but also quick heat radiating, so just controlled the temperature rise of led chip, improved light efficiency and the power of high-power LED light source, what modules light fixture no matter adopt to make optical efficiency and power relatively stable.

Below in conjunction with accompanying drawing the utility model is described in further detail.
