Abstract
The utility model relates to a PCB for LED positioning, belonging to the large-power LED lighting field, comprising a PCB, a LED positioning hole on the PCB, a periphery bonding pad of the LED positioning hole, a copper foil route between the bonding pads, a bonding pad for connecting the LED and a drive power supply at the two ends of the PCB, an installation screw hole of the PCB, a quadric optical lens installation screw hole. The PCB prevents the lamp beauty from being influenced due to LED connection by conductor and determines the LED installation position, improves the production technology of the LED lamp and increases the production efficiency.
Description
Affiliated technical field
The utility model belongs to great power LED mounting process field.
Background technology
LED is as a kind of new type light source, and is low with its energy consumption, the life-span long, environmental protection is generally promoted.Because the luminous flux of single LEDs is low, generally all be that plurality of LEDs links together in the light fixture, at present, be connected with dual mode: 1, needed LED in the single light fixture all is welded on the aluminium base, links to each other by the Copper Foil line on the aluminium base between each LED at plurality of LEDs; 2, the corresponding aluminium base of a LEDs connects with lead by the positive and negative electrode pad on the aluminium base between each LED.All there is defective in above dual mode, if single LEDs occurs after Reflow Soldering unusually in first kind of mode, the LED that then needs to dismantle crosses Reflow Soldering again, may change other LED colour temperature like this, accelerate light decay.The position of second way LED is easy to generate deviation effects light type, and has between the aluminium base that to influence light fixture than long lead attractive in appearance.
Summary of the invention
The utility model is for improving existing led light source mounting process, and visual effect is enhanced productivity, and has designed a kind ofly to single LEDs light source location, reduces the PCB of LED lamp interior line.
The technical solution of the utility model:
A kind of PCB that is used for the LED location, described PCB comprises that PCB installs screw hole and secondary optical lens is installed screw hole, be used for fixing PCB and secondary optical lens, described PCB also comprises the LED locating hole, pad is arranged around the LED locating hole, can directly be connected with pad on the LED aluminium base, there are pad and Copper Foil line in described PCB two ends, are used for being connected between LED and the driving power.All LED all connect by the Copper Foil line on the PCB, and PCB is connected by the Surface Mount wire jumper with LED, and it is attractive in appearance to have avoided the connection of use long lead to influence light fixture.
Description of drawings
Fig. 1: the utility model plane example structure figure.
Fig. 2: the utility model exemplifying embodiment structure chart.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.The following stated only is a preferred implementation of the present utility model, and every any form of being done based on creative ideas of the present utility model is modified or change, all belongs to the category of the utility model patent.
Referring to Fig. 1, a kind of PCB that is used for the LED location shown in Figure 2, by described pcb board 1, LED locating hole 2, secondary optical lens screw hole 4 is installed, PCB installs Copper Foil cabling 6 between screw hole 3, LED locating hole peripheral pads 5, the pad, the pad 9 that two row LED are connected, the pad 7 of selecting electric power loop, described pad 7 inserted the pad 10 and the pad 8 that is used to be connected the power supply input-output line of electric power loops.
Described pcb board 1 is installed screw hole 3 by PCB and is installed on the radiator, LED aluminium base 11 is put into LED locating hole 2, with screw secondary optical lens being installed screw hole 4 by hole 13 and secondary optical lens is installed on the PCB, pad 12 on the aluminium base links to each other with LED locating hole 2 peripheral pads 5 by the Surface Mount wire jumper, link to each other by the Copper Foil cabling on the pcb board 6 between the two horizontal adjacent LED, every row 6 LEDs are series connection in this way all, first connects the pad 9 of described pcb board both sides with last LEDs and is connected with pad 7 in every group of series LED, selecting an electric power loop by pad 7 again and link to each other, will insert power supplys with pad 10 corresponding bonding pad 8 with the pad 10 in this loop. the row of two on same pcb board LED can be connected with pad 5 by pad 9 and connects. and the LED on the different pcb boards connects can pass through pad 9, pad 7, pad 10 is connected with pad 8.
