The locating dowel adjacent with described close-fitting hole it is provided with on the step wall of described first step, described first step
Top is provided with the second boss for mounted lens, the step surface of described second boss offers annular recessed
Groove, arranges three pits having for location in described annular groove.
Wherein, the top of described cylindrical lamp holder offers PIN needle hole, the plane bottom described PIN needle hole
On be provided with the reinforcement for preventing PIN needle hole from ftractureing.
Wherein, the angle between sidewall and the plane of described cylindrical light head of described cylindrical lamp holder is big
In 90 degree less than 100 degree.
Wherein, the width of described first elongated slot one end is less than the width of the other end.
Wherein, the bottom surface of described first elongated slot is consistent with the radian of described outer circumference surface.
Wherein, the hole wall in described close-fitting hole is symmetrically arranged with U-lag.
Beneficial effects of the present invention: the outer circumference surface of ceramic heat-dissipating main body of the present invention is the arc-shaped of outwardly convex,
And the bottom of ceramic heat-dissipating main body is provided with boss, arrange between the bottom of described boss and described outer circumference surface
Flange, the top of described outer circumference surface is had to be provided with and the cylindrical light of described outer circumference surface one sintering
Head, described outer circumference surface uniformly offers the first elongated slot, the described first curved setting of elongated slot, and described
First elongated slot is through described flange and runs through described boss, is provided with for putting at the axle center at described boss top
Putting the first step of lamp plate assembly, the bottom of described first step is provided with and connects with described cylindrical lamp holder
Circular hole, the step surface of described first step is provided with the close-fitting hole for close-fitting plastic nut, described
Being provided with the locating dowel adjacent with described close-fitting hole on the step wall of one step, the top of described first step sets
It is equipped with the second boss for mounted lens, the step surface of described second boss offers annular groove, institute
Three pits for location it are provided with in stating annular groove.Lamp holder and outer circumference surface one sintering, eliminate
The assembling of lamp holder, the first elongated slot of the arc that outer circumference surface is offered, and the first elongated slot are distributed in outer circumference surface,
Area of dissipation is increased, and radiating effect is more preferable.Present configuration is simple, good heat dissipation effect, and assembling letter
Single, use manpower and material resources sparingly.

Detailed description of the invention
1 to accompanying drawing 4 further illustrated the technology of the present invention by detailed description of the invention below in conjunction with the accompanying drawings
Scheme.
A kind of ceramic heat-dissipating main body for shot-light, the outer circumference surface of ceramic heat-dissipating main body is the circle of outwardly convex
Arcuation, and the bottom of ceramic heat-dissipating main body is provided with boss 1, the bottom of described boss 1 and described outer circumference surface
Between be provided with flange 2, the top of described outer circumference surface be provided with and described outer circumference surface one sintering
Cylindrical lamp holder 3, described outer circumference surface uniformly offers the first elongated slot 4, and described first elongated slot 4 is curved
Arrange, and described first elongated slot 4 through described flange 2 and runs through described boss 1, described boss 1 top
Be provided with the first step 5 for placing lamp plate assembly at axle center, the bottom of described first step 5 be provided with
The circular hole that described cylindrical lamp holder 3 connects, the step surface of described first step 5 is provided with for close-fitting
The close-fitting hole 6 of plastic nut, the step wall of described first step 5 is provided with adjacent with described close-fitting hole 6
Locating dowel 7, the top of described first step 5 is provided with the second boss 8 for mounted lens, and described second
Offering annular groove on the step surface of boss 8, arranging three in described annular groove has recessed for position
Hole.Lamp holder and outer circumference surface one sintering, eliminate the assembling of lamp holder, the arc that outer circumference surface is offered
First elongated slot, and the first elongated slot is distributed in outer circumference surface so that area of dissipation increases, and radiating effect is more preferable.
Present configuration is simple, good heat dissipation effect, and assembling is simple, uses manpower and material resources sparingly.
The top of described cylindrical lamp holder 3 offers PIN needle hole, and the plane bottom described PIN needle hole sets
It is equipped with the reinforcement for preventing PIN needle hole from ftractureing.The setting of reinforcement is subject to when decreasing because of PIN needle riveted
Power and the risk of plane cracking bottom the PIN needle hole caused so that heat sink body reliability is higher.
Angle between sidewall and the plane at described cylindrical lamp holder 3 top of described cylindrical lamp holder 3 is more than
90 degree are less than 100 degree.This design is beneficial to the demoulding and the molding of product of mould.
The width of described first elongated slot 4 one end is less than the width of the other end.
The bottom surface of described first elongated slot 4 is consistent with the radian of described outer circumference surface.The design increases first long
The area of dissipation of groove bottom, improves the radiating efficiency of ceramic heat-dissipating main body.
It is symmetrically arranged with U-lag on the hole wall in described close-fitting hole 6.Close-fitting hole and plastic nut press together,
Owing to, during installing screw, plastic nut can be coordinated on hole wall symmetrical with this by certain torsion
The U-type groove arranged, it is possible to effective wall is because of the torsion former problems such as screw not tight that thus result in such as excessive
Occur.
