Detailed description of the invention
Below in conjunction with accompanying drawing 1 to accompanying drawing 4 and further illustrate the technical solution of the utility model by detailed description of the invention.
A kind of ceramic heat-dissipating main body for shot-light, the outer circumference surface of ceramic heat-dissipating main body is the circular-arc of outwardly convex, and the bottom of ceramic heat-dissipating main body is provided with boss 1, between described boss 1 and the bottom of described outer circumference surface, be provided with flange 2, the top of described outer circumference surface is provided with the cylindrical lamp holder 3 forming with described outer circumference surface one sintering, on described outer circumference surface, evenly offer the first elongated slot 4, the curved setting of described the first elongated slot 4, and described the first elongated slot 4 is through described flange 2 and run through described boss 1, the axle center place at described boss 1 top is provided with the first step 5 for placing lamp plate assembly, the bottom of described first step 5 is provided with the circular hole connecting with described cylindrical lamp holder 3, on the step surface of described first step 5, be provided with the close-fitting hole 6 for close-fitting plastic cement nut, on the step wall of described first step 5, be provided with the locating dowel 7 adjacent with described close-fitting hole 6, the top of described first step 5 is provided with the second boss 8 for mounted lens, on the step surface of described the second boss 8, offer annular groove, three pits that are useful on location are set in described annular groove.Lamp holder and outer circumference surface one sintering, the assembling of having saved lamp holder, the first elongated slot of the arc of offering on outer circumference surface, and the first elongated slot is distributed in outer circumference surface, and area of dissipation is increased, and radiating effect is better.The utility model is simple in structure, good heat dissipation effect, and assembling is simple, uses manpower and material resources sparingly.
