The edge of an extension part of the bracket is provided with a discontinuous obstruct section, and siphon phenomena generated on the edge of the extension part by encapsulation colloid can be controlled to only occur in the discontinuous obstruct section, therefore, the technical efficacy that the occurrence of the siphon phenomena is controlled to prevent oversize change of the size of the encapsulation colloid is achieved.
Description
Technical field
A kind of light-emitting diode support structure refers in particular to a kind of edge in support the light-emitting diode support structure of the obstruct section of discontinuous with the control siphonage is set.
Background technology
In recent years, because light-emitting diode (Light Emitting Diode, LED) have that power consumption is low, component life is long, need not warm up advantages such as lamp time and reaction speed be fast, add that its volume is little, vibration resistance, be fit to volume production, therefore light-emitting diode generally is used on the indicator light and display unit of information, communication and consumption electronic products, as mobile phone and personal digital assistant (Personal Digital Assistant, PDA) screen backlight source, various outdoor display, traffic lights and car light etc.
Below a kind of light-emitting diode support structure will be described, and please refer to shown in " Fig. 1 " that " Fig. 1 " illustrates the schematic perspective view into existing light-emitting diode support structure; Existing light-emitting diode support structure includes: first support 51 and second support, 52, the first supports 51 include first top ends 511 and first extension, 512, the second supports 52 include second top ends 521 and second extension 522.
Therefore, please refer to shown in " Fig. 2 ", " Fig. 2 " illustrates the schematic perspective view into existing light-emitting diode support structure improvement; The trickle burr that produced for second extension, 522 edges of first extension 512 of eliminating first support 51 and second support 52, when making light-emitting diode support structure, then need to increase flattening course, the trickle burr that second extension, 522 edges of first extension 512 of place first support 51 and second support 52 are produced when using the elimination punching press.
Flattening course is at second extension, 522 edges of first extension 512 of first support 51 and second support 52 and forms chamfering 54; promptly can eliminate the trickle burr that second extension, 522 edges of first extension 512 of first support 51 and second support 52 are produced by the formed chamfering 54 of flattening course; when again first support 51 and second support 52 being encapsulated by packing colloid; because need be with first top ends 511 and first extension, 512 parts of first support 51; and second top ends 521 of second support 52 and second extension, 522 parts; be inserted in the liquid packing colloid in the mode of falling to insert; after packing colloid solidifies; can be with first top ends 511 and first extension, 512 parts of first support 51; and second top ends 521 of second support 52 and first extension, 512 parts are packaged in packing colloid, and light-emitting diode chip for backlight unit 53 is formed protection.
Yet; because second extension, the 522 process chamferings 54 that flattening course produced of first extension 512 of first support 51 and second support 52; when first support 51 and second support 52 are carried out encapsulation process; liquid packing colloid then can be owing to chamfering 54 siphonage that produces; promptly can make the size of packing colloid after solidifying to change, more likely can't form protection light-emitting diode chip for backlight unit 53.
In sum; prior art has existed light-emitting diode support structure behind the process flattening course always since the midium or long term as can be known; the siphonage that produces and cause the packing colloid size to change and can't form the problem of protection to light-emitting diode chip for backlight unit; therefore be necessary to propose improved technological means, solve this problem.
The utility model content
Because prior art exists light-emitting diode support structure behind the process flattening course; the siphonage that produces and cause the packing colloid size to change and can't form the problem of protection to light-emitting diode chip for backlight unit; the utility model discloses a kind of LED support structure-improved then, wherein:
The LED support structure-improved that the utility model disclosed, it comprises: first support and second support, first support include first top ends and first extension, and second support includes second top ends and second extension.
Wherein, first extension extends downwards from first top ends, and first top ends is provided with the depressed part of indent, and depressed part is used for affixed light-emitting diode chip for backlight unit, and the edge of first extension is concaved with at least one obstruct section; Second extension extends downwards from second top ends, and second top ends and light-emitting diode chip for backlight unit form and electrically connect, and the edge of second extension is concaved with at least one obstruct section.
And be to form disjunct chamfering by edge at first extension and second extension at the obstruct section that first extension and second extension are arranged with, the section length that intercepts section can be random length or fixed numeric values, and intercept the edge that section can be evenly distributed in first extension and second extension, or intercept the edge that section can be allocated in first extension and second extension arbitrarily.
The section of depressed part is that one of them is arranged at the top ends of first support with semicircular in shape or V-type shape, and when the section of depressed part presents the V-type shape, the angle of offering of depressed part opening is an an angle of 90 degrees, light that light-emitting diode chip for backlight unit the produced reflecting surface by depressed part can be reflected by this, make its light source that presents approximate directional light, use the luminosity that improves light-emitting diode chip for backlight unit.
And the LED support structure-improved more can comprise packing colloid, is used to be coated on first top ends and second top ends, and partly is coated on first extension and second extension, uses that light-emitting diode chip for backlight unit is formed protection.
The structure that the utility model disclosed as above; and the difference between the prior art be the utility model at the second extension edge of first extension of first support and second support flattening course by discontinuous; form the obstruct section of at least one depression with the second extension edge at first extension of first support and second support; promptly form disjunct chamfering at first extension of first support and the second extension edge of second support; liquid packing colloid only can produce siphonage in intercepting section; can effectively control siphonage by this takes place; and can not allow the size of packing colloid after solidifying produce too big variation, promptly can effectively protect light-emitting diode chip for backlight unit.
