Abstract
This utility model provide a kind of LED heat scald locating dowel, include base with protrude from described base upwardly extending locating dowel cylinder, its feature is to be provided with escape groove in described base and locating dowel cylinder joint；Described escape groove avoids the corner angle of LED-baseplate when being used for installing.It has such advantages as：1. mould structure is simple, and dynamic model is with meat it is not necessary to increase the movable devices such as core pulling.2. locating effect is reliable, and assembling is unique, practical.
Description
Technical field
This utility model is related to a kind of light fixture manufacturing technology, is specifically applied to the various light fixture systems containing burn structure
In making, for assembling a kind of burn positioning rod structure of LED.
Background technology
At present, it is widely used in car light industry with LED, LED headlight already becomes a kind of trend it is therefore desirable to have steady
Fixed reliable LED positions and to realize assembling.Many light fixtures all pass through burn form positioning LED now, due to mould processing factors,
Fitting surface is led to inherently to there is chamfering, it is docile to there is fitting surface after assembling LED, leads to LED deviation theory position, and then
Impact optical property.And LED positioning bad often bring extremely serious consequence, as bad in optical property, whole lamp is scrapped.
Existing burn as depicted in figs. 1 and 2 positions rod structure and its installation with LED-baseplate is illustrated, in locating dowel 101
The chamfering 102 existing and base 100 between influences whether being accurately positioned and installing of LED-baseplate 200.
Utility model content
Technical problem to be solved in the utility model is that providing one kind to be advantageously implemented accurately, stably assembles LED
LED heat scald locating dowel.
Its technical problem to be solved can be implemented by the following technical programs.
A kind of LED heat scalds locating dowel, and including base and protrude from described base upwardly extending locating dowel cylinder, it is special
Point is to be provided with escape groove in described base and locating dowel cylinder joint；Described escape groove avoids LED-baseplate when being used for installing
Corner angle.
As the improvement further of the technical program, described escape groove is cannelure.
As one of preferred embodiment of the present utility model, the longitudinal section of described escape groove is in 1/4 circle.
Also serve as one of preferred embodiment of the present utility model, the groove width of described escape groove and groove depth are equal.
As the further improvement of the technical program, at least one section of described escape groove and described locating dowel damaged surface
The cell wall of rounding off.
The same further improvement as the technical program, described susceptor surface is with described escape groove cell wall joint
Good at right angles turnover.
Also as preferred embodiment of the present utility model, the section of described escape groove is U-shaped.
LED heat using technique scheme scalds locating dowel, arranges one by the corner connecting in cylinder and base
Avoid slot structure, and then avoid the impact to assembly precision and laminating degree for the chamfering existing at corner in prior art；Real
Show LED accurately, stably assemble；This precise and stable burn structure can bring stable optical property to assembly light fixture.
Brief description

For the ease of expressing and keeping simplified form, in above-mentioned view, all do not mark hatching；
In figure：100th, 400 bases 101,301 locating dowel 102 chamfering 200,500 LED-baseplate
302 escape groove 3011 cylinder 3021,3022 cell wall, 401 surface 402 corner angle
Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment of the utility model is described in further detail.
LED heat as shown in Figures 3 to 5 scalds locating dowel and its application is illustrated, in burn locating dowel 301 and base 400 phase
The place connecing has opened up an annular escape groove 302, the post of the one of cell wall 3021 of escape groove 302 and locating dowel 301
Face 3011 is in rounding off trend, and the change of the concave-convex surfaces such as obvious step in both joints.Escape groove 302 is another
The cell wall 3022 at end forms the structure of corner angle 402 with surface 401 joint of base 400, illustrates by profile, this corner angle 402
Section is right angle；The section of whole escape groove 302 is in the cross-section structure of 1/4 circle.Its width is equal with depth.
This escape groove 302 actually plays the effect of a technology groove, can prevent in LED assembling process because technique is fallen
Angle leads to assemble unstable, and technology groove physical dimension can also determine according to practical situation.
As shown in figure 5, LED-baseplate its corner angle can be realized completely avoiding when mounted, its two sides can completely and bottom
The cylinder 3011 of the surface 401 of seat and locating dowel 301 realizes laminating.
Certainly, the structure of escape groove can also be designed to bottom surface is U-shaped version.
The said structure that this utility model provides is that existing LED heat scalds locating dowel structure optimization, and this structure is passed through in burn
Column bottom increases technology groove, prevents from leading to LED positioning bad because fillet in processing, improves optical stability.This structure is passed through
Increase technique slot structure at 1 and reach the impact avoiding technique fillet that LED is positioned.Have such advantages as：
1. mould structure is simple, and dynamic model is with meat it is not necessary to increase the movable devices such as core pulling.
2. locating effect is reliable, and assembling is unique, practical.
