Description
Technical field
The utility model relates to LED illumination light source technical field, particularly relates to a kind of light source board fixture.
Background technology
LED, as the electric light source of a new generation, can design all multiple types light fixture products.LED lamp product in process of production, LED light source plate needs to fix, it is generally the screw of three circumference uniform distributions, be fixed on radiator or cover of driver, the problem how this screw hole that just there are three circumference uniform distributions on a radiator or cover of driver is aimed at the screw hole on light source board, could lock screw after aligning.In assembling process, after putting light source board, assembler, by visual aligning screw hole, many times regulates, the screw hole on radiator and light source board is aimed at, then screwing screw.Production efficiency is low, and lamp assembled expense increases.
So need a kind of optimization assembling mode badly, enhance productivity, make the technology that assembly cost declines.
Utility model content
In view of the above problems, the utility model provides a kind of light source board fixture.
A kind of light source board fixture, is characterized in that, comprising:
Cover of driver, arranges a boss in cover of driver center;
Radiator, offer the first through hole with boss form fit, and radiator is sheathed on boss by the first through hole, to make radiator and the complete contraposition of cover of driver;
Light source board, offers the second through hole with boss form fit, fold and establish on a heat sink, and light source board is sheathed on boss by the second through hole, to make light source board and the complete contraposition of cover of driver.
Above-mentioned device, is characterized in that, described boss profile is trapezoidal.
Above-mentioned device, is characterized in that, described boss is hollow design.
Above-mentioned device, is characterized in that, described first through hole and described second through hole are trapezoidal.
Above-mentioned device, is characterized in that, described light source board shady face coated with thermally conductive material.
Above-mentioned device, is characterized in that, described cover of driver is evenly provided with some first screws.
Above-mentioned device, is characterized in that, described light source board and described radiator coupling are provided with the second screw and the 3rd screw.
Above-mentioned device, is characterized in that, described cover of driver, described light source board and described radiator are circle.
Above-mentioned device, is characterized in that, the material of described cover of driver is aluminium.
In sum, the utility model proposes a kind of light source board fixture, cover of driver, radiator and light source board will all be arranged the identical asymmetric apertures of planar graph, utilize the direction uniqueness of this asymmetric control, complete the orientation of light source board opposite heat sink or cover of driver, solve directionality problem when LED light source plate is fixed, make assembling simpler.
Accompanying drawing explanation
With reference to appended accompanying drawing, to describe embodiment of the present utility model more fully.But, appended accompanying drawing only for illustration of and elaboration, do not form the restriction to the utility model scope.
Fig. 1 is the utility model cover of driver structural representation;
Fig. 2 is the utility model light source board structural representation;
Fig. 3 is the utility model heat spreader structures schematic diagram.
Detailed description of the invention
In order to make the technical solution of the utility model and advantage more should be readily appreciated that, be described in further detail below in conjunction with accompanying drawing.Should illustrate, specific embodiment described herein only in order to explain the utility model, and is not used in restriction the utility model.
As shown in Figure 1-Figure 3, a kind of light source board fixture of the utility model design, comprising having:
Cover of driver, this cover of driver is provided with a boss 1, and this boss 1 can be arranged on the central point of cover of driver, also can be arranged on other any position on cover of driver, in the utility model, is preferably arranged on the center position of cover of driver;
Radiator, be arranged on this cover of driver, this radiator arranged one first through hole 3, the shape of this first through hole 3 is identical with the flat shape of cover of driver convex platform 1, so just the through hole of this radiator can be mated with the boss 1 of cover of driver, radiator muff-joint is located on cover of driver;
Light source board, folding establishes on a heat sink, and one second through hole 4 is offered at the center of this light source board, and this second through hole 4 is identical with the shape of the first through hole on radiator, radiator and tabula rasa, just also through this second through hole, are all fixed according to same direction by the boss of cover of driver.
In the utility model, the profile of boss is asymmetric, this ensure that cover of driver, radiator and light source board are all directions, they can be fitted together very easily like this, do not need capturing position repeatedly when installation is fixing.So the shape of boss can be trapezoidal, also can be triangle, or other asymmetric shapes, preferably, the shape of the boss in the utility model, the first through hole and the second through hole is trapezoidal, when manufacturing, the shaped slightly of the first through hole and the second through hole is greater than the external diameter of boss, sheathedly eaily can enter like this, and then is fixed into an entirety.
In the utility model, boss on cover of driver is hollow design, be conducive to cross-under power line like this on light source board, cover of driver also arranges some screw holes 2, in order to coordinate the screw hole 2 of cover of driver and form an entirety, radiator and light source board are provided with some screw holes equally, these devices can be fixed in the same direction like this.In actual life, the profile of LED may be circular, also may be other shapes, such as square and so on.In the utility model, circular with LED, some screw holes are evenly distributed in cover of driver circumferentially, so radiator and light source board are circumferentially equally also evenly provided with some screws, in order to easy for installation and fixing object, preferred screw hole design is three, is distributed on circumferentially in equilateral triangle shape.So just do not need a lot of screw, not only attractive in appearance but also save labour.
In the utility model, the backside coating of light source board has Heat Conduction Material, so just can by heat energy transfer that light source board produces on radiator, further, cover of driver is designed to that Heat Conduction Material makes, such as metal or the reasonable alloy of other heat conduction, in order to the consideration of the aspect such as economic and attractive in appearance, preferably, the material of cover of driver is aluminium, so very light.
After cover of driver, light source board and radiator are assembled according to same direction, lock screw, be fixed, because cover of driver and light source board be all asymmetric apertures, thus only have a direction, have and only have a direction to put down light source board, thus aligning screw hole, direction is not right, and light source board fails to lay down, solve directionality problem when LED light source plate is fixed like this, make assembling more simply light.
By illustrating and accompanying drawing, giving the exemplary embodiments of the ad hoc structure of detailed description of the invention, based on the utility model spirit, also can do other conversion.Although above-mentioned utility model proposes existing preferred embodiment, but these contents are not as limitation.
For a person skilled in the art, after reading above-mentioned explanation, various changes and modifications undoubtedly will be apparent.Therefore, appending claims should regard the whole change and correction of containing true intention of the present utility model and scope as.In Claims scope, the scope of any and all equivalences and content, all should think and still belong in intention of the present utility model and scope.
