Summary of the invention

The utility model provides a kind of material internal heat-conduction principle that utilizes at above technical problem, and the heat of light source is conducted diffusion, and the abundant convection current of adopting air and radiating surface again is to realize the factory lamp of secure heat dissipation.

The technical solution of the utility model is: comprise lampshade, power supply and light source, described light source adopts LED integrated optical source, and it also comprises the radiator that is located at the column between power supply and the lampshade; The middle part, bottom surface of described radiator is provided with the continuing surface that is used to install described LED integrated optical source with efficient heat conductivity, and LED integrated optical source is fixedly connected on the described continuing surface; Described lampshade is fixedly connected on the bottom surface of described radiator; All establish the heat radiation wing on the outer surface of described radiator.

Described radiator also is provided with mesopore, and described power supply links to each other by the lead that is arranged in the mesopore with light source.

Described radiator cross section profile is rounded, and described heat radiation wing is T type, three forked types, selenodont or straight rod type.

Described radiator cross section profile is rectangular, and described heat radiation wing comprises four the main wings and the auxilliary wing of being located on the described main wing that are positioned on the diagonal.

The surface of described heat radiation wing has tongue and groove.

The inner surface of described lampshade is provided with the male and fomale(M﹠F) that luminous intensity distribution is used.

The utility model adopts LED integrated optical source, has solved the structural complexity that adopts several simple grains LED to be brought, and has greatly reduced the light source volume.The radiator that is adopted in the utility model adopts highly heat-conductive material to make, as aluminium alloy, with LED integrated optical source directly connects with its on, assurance is connection with heat conduction between the two, guarantees that the heat of LED integrated optical source can promptly conduct to this radiator; Radiator outer surface design has some heat radiation wings, as the T shape etc., use the die-casting technique one-shot forming, forms rule special use thermal convection current passage, increased and air between area of dissipation, be convenient to the heat radiation of LED integrated optical source.The lampshade that light fixture is supporting, the lighting requirement for the illumination that makes irradiation area and the light distribution uniformity reach various factory works is designed to various geometries.Requirement with the user.

The utlity model has following beneficial effect: 1,, make the light source volume greatly reduce, make fitting structure simpler, reasonable, attractive in appearance than the simple grain led light source owing to adopt LED integrated optical source.2, except that the thermal resistance of LED and radiator itself, there are not other any thermal resistances, reduce the thermal resistance of heat transfer path significantly, and increased the efficiently radiates heat area greatly, greatly promoted the integral heat sink ability of light fixture, prolonged the service life of light fixture; 3, because designs simplification can reduce small product size and weight, make product more tend to miniaturization, the high-altitude is used safer; 4, the appropriate design of supporting lampshade, the light loss consumption is little, and light distribution is even in the irradiation area.The utility model is particularly useful for the great power LED factory lamp.
