Description
Technical field
The utility model relates to a kind of heat radiation pcb board and LED.
Background technology
Printed circuit board, also known as printed circuit board (PCB), is the supplier of electronic devices and components electrical connection.Its development has the history of more than 100 year; Its design mainly layout design; Adopt the major advantage of circuit board to be the mistake greatly reducing wiring and assembling, improve the gentle productive labor rate of Automated water.
How the wiring board of long narrow arranges wire structures, to meet circuit radiating requirements and cabling demand, two solder joints of more general small-sized electric devices can only be arranged in the circuit board along its length, and in order to meet cabling demand (can not be short-circuited), can other partial corrosions except the copper cash part for walking wire routing, to ensure that its cabling is convenient, but in use often because heat radiation reason causes wiring board to affect the useful life of electronic product under big current or high enthusiasm condition.
Particularly on LED lamp bar, particularly evident to the requirement of heat dispersion.
Utility model content
For the deficiency that prior art exists, the first object of the present utility model is to provide a kind of heat dispersion high and can meets the one heat radiation pcb board of wiring requirements.
For realizing above-mentioned first object, the utility model provides following technical scheme: a kind of heat radiation pcb board, be set to rectangle, its width range is at 11mm to 13mm, some pad groups are had along the horizontal spaced set of described pcb board, each pad group includes two component pads for welding electric device, one end of described pcb board is provided with power supply weldering group, described power supply weldering group is provided with and comprises positive terminal pad and negative terminal pad for welding with external power source, described pcb board comprises positive cabling portion, negative cabling portion and radiating part, described radiating part comprises some bronze medals be covered in component pads, connected by copper cash between adjacent bronze medal, the spacing being positioned at the adjacent bronze medal of radiating part is less than 2mm, between adjacent pad group, serial or parallel connection is arranged, and be series between positive terminal pad and negative terminal pad and form loop.
Because the pad group on this pcb board laterally can only arrange (limiting by its width), also comparatively simple based on its Wiring structure of same reason, except power pad, adjacent pad group can only couple successively, so the utility model marks off three cabling portions, positive cabling portion, negative cabling portion and radiating part, by increasing the area (bronze medal be wholely set) of its copper cash on electric device solder joint, the area of dissipation of wiring node is increased greatly, and spacing between adjacent bronze medal can not more than 2mm, to ensure its radiating effect.
The utility model can be set to further: described power supply weldering group is arranged at one end of pcb board, described negative cabling portion be covered with copper cash and connect negative terminal pad with from negative terminal pad bronze medal farthest.Described positive cabling portion is covered with copper cash and connects positive terminal pad and the bronze medal nearest apart from positive terminal pad.Be arranged on same one end of pcb board by power supply being welded group, one can increase it in the convenience of external module cabling, and two compare and are separately positioned on two ends, and copper cash cabling is longer, further increases heat dispersion.
The utility model can be set to further: described positive cabling portion also comprises extension apparatus, and the copper cash of described extension apparatus is used for dispelling the heat to bronze medal.Be that difference is by the copper cash covered equally by extension apparatus, copper cash one end is extended by positive pole solder joint, and what parts the other end does not take over, and forms an empty cabling portion like this, too increases heat dispersion.
Second object of the present utility model is the LED providing a kind of high heat radiation.
For realizing above-mentioned second object, the utility model provides following technical scheme: with a kind of LED of above-mentioned pcb board, described component pads is welded with LED lamp bead.Adopt big current heat dissipation technology, make the timely conduct radiation of LED light source heat energy in air, thus solve because heater own temperature is too high and shorten its useful life.
The utility model can be set to further: two described LED lamp bead parallel connections form luminescence unit, and described luminescence unit is arranged in series and forms loop between external power source.String is also reasonable: the change not affecting other branch road operating current because a LED lamp pearl open circuit, cause the situation that other branched line operating current raises, also not because of lamp pearl open circuit, cause the change of other local road design parameter and useful life of shortening light source or the phenomenon of burning.
By adopting technique scheme, compared to existing technology: the utility model solves LED light source and electronic devices and components, because of the little heat of the conventional wires node area of dissipation not easily conduct radiation defect of going out in time, greatly extends the useful life of electronic devices and components.String is also reasonable: the change not affecting other branch road operating current because a LED lamp pearl open circuit, cause the situation that other branched line operating current raises, also not because of lamp pearl open circuit, cause the change of other local road design parameter and useful life of shortening light source or the phenomenon of burning; Reduce light decay because of good heat dissipation effect, extend the useful life of LED light source; Anti-ripple is stronger than conventional wires circuit.
