Abstract
The utility model provides a kind of overlength lamp bar, including long lamp bar and bottom circuit board, the long lamp bar is welded on the bottom circuit board, wherein, the bottom circuit board includes at least one pad group, positive wiring, negative wiring and ground wire, the positive wiring, negative wiring and ground wire are arranged on the bottom circuit board, the pad group is connected between the positive wiring and the negative wiring, the utility model is using the above structure, it realizes and is arranged on the bottom circuit board in multiple pads, again by the manufacture in long lamp bar solder pad, it avoids and needs for LED to be welded in lamp bar by SMT patch in the prior art, it is then assembled into the assembling mode of fluorescent tube, it avoids fluorescent tube there are calorific values and is big, cause the thermal resistance of paster LED excessively high, thus the problem of causing the service life reduction of LED lamp tube.
Description
Technical field
The utility model relates to lighting area, in particular to a kind of overlength lamp bar.
Background technique
LED lamp tube is also commonly called as light pipe, fluorescent tube, and using LED as illuminator, LED lamp pipe has many good qualities light source,
It is generally used for general lighting, office building, market, restaurant, school, family, the room lightings such as factory；
However be all SMT adopting surface mounted LED in present market routine LED lamp tube, this light emitting source is that many LED pass through
SMT patch is welded in lamp bar, is then assembled into fluorescent tube；But that there are calorific values is big for this LED lamp tube, leads to the heat of paster LED
Hinder it is excessively high, to cause the service life reduction of LED lamp tube.
Utility model content
In order to overcome the drawbacks described above of the prior art, the utility model proposes a kind of overlength lamp bars, pass through the utility model
A kind of overlength lamp bar proposed can be realized directly to shine without the welding of SMT patch, and high with thermal coefficient and low thermal resistance is excellent
Point.
In order to solve the above-mentioned technical problem, the technical solution of the utility model are as follows:
A kind of overlength lamp bar, including long lamp bar and bottom circuit board, long lamp bar are welded on the bottom circuit board,
Wherein, the long lamp bar includes LED light bar and at least two first power pads,
The side of the LED light bar is arranged in first power pad.
Further, the bottom circuit board includes at least one LED pad group, at least two second power pads, just
Wiring, negative wiring and ground wire；
The positive wiring, the negative wiring and the ground wire are arranged on the bottom circuit board, the LED pad group
It is connected between the positive wiring and the negative wiring and is weldingly connected with the LED light bar, second power pad is set
It sets in the bottom circuit board and is connected with the positive wiring and the negative wiring, second power pad is also with described
One power pad is weldingly connected.
By adopting the above technical scheme, it is welded by being arranged on the bottom circuit board in multiple pads, then by long lamp bar
Mode on pad, which avoids, to be needed for LED to be welded in lamp bar by SMT patch in the prior art, is then assembled into the group of fluorescent tube
Dress mode, avoids fluorescent tube there are calorific values big, causes the thermal resistance of paster LED excessively high, to cause the service life reduction of LED lamp tube
The problem of.

It is connected between the positive wiring and the negative wiring and is weldingly connected with LED light bar 110, the second power pad setting
It is connected in the bottom circuit board and with the positive wiring and the negative wiring, second power pad is also powered with first
Pad 120 is weldingly connected.
Second power pad with the first power pad 120 for being weldingly connected and to the positive wiring and described negative
Wiring power supply；
The positive wiring and the negative wiring are used to power with to the LED pad group；
The LED pad group is for fixing long lamp bar 100 and powering to long lamp bar 100.
In a concrete application scene of the invention, when user needs using the utility model, user first will be originally practical new
Type is installed on external lamp bracket, and the supply lines of lamp bracket is coupled at the first power pad 120, when user opens for establishing by cable
Guan Shi, at second power pad, the positive wiring described at this time and the negative wiring are used for the power supply of the first power pad 120
It powers with to the LED pad group, long lamp bar 100 lights, to play illuminating effect.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
