Description
Technical field
The present invention relates to LED, especially relate to a kind of LED string using constant current-supplying and manufacturer thereof
Method.
Background technology
Along with socioeconomic fast development, LED as exploitation and the powerful of decoration,
Use more and more universal, it has also become a beautiful landscape that enterprise's mark publicity is indispensable with beautifying city
Line.Along with every profession and trade product, the increasingly sharpening of service competition, how to be the corporate image of oneself, commodity,
Mark builds a unique publicity image to attract consumer's eyeball, and branding strategy has become marketing work
The most important thing, the various visual features forms such as " outdoor sign system " and leaflet embody day by day
Its irreplaceable effect.LED string product has been widely used various place.
LED string currently on the market mainly divides LED flexible light string and LED hard lamp string two kinds, its difference
It is as follows: 1, flexible LED lamp string is to use FPC to do assembling wiring board, assembles with paster LED,
The thickness of its product is only the thickness of one piece of coin, does not takes up space；Universal specification have 30cm length 12 LEDs,
24 LEDs and 50cm length 15 LEDs, 30 LEDs etc..Also have 60cm, 80cm etc., different
User have different specifications.And can arbitrarily cut off, can also arbitrarily extend and luminescence is not by shadow
Ring.2, LED hard lamp string is to do assembling wiring board with PCB hardboard, and the useful paster LED of LED assembles
, the most useful straight cutting LED carries out assembling, optionally different and use different elements.Hard lamp string
Advantage is to be easier to fix, and processes and install the most more convenient；Shortcoming is arbitrarily to bend, uncomfortable
Close irregular place.Hard lamp string paster LED have 12 LEDs, 30 LEDs, 36 LEDs,
The good plurality of specifications such as 54 LEDs；With straight cutting LED have 18,24,36,48 etc. no
Same specification, have front also has side, lateral emitting be again Wall-shaped lamp string.Adding of these two kinds of lamp strings
Work complex process, relatively costly.
Summary of the invention
For overcoming above-mentioned shortcoming, the present invention provides that a kind of processing is simple, low cost, have indivedual lamp to damage
Do not interfere with the LED string using constant current-supplying of Integral luminous performance.
It is an object of the invention to be realized by techniques below measure, a kind of LED using constant current-supplying
String, including multiple lamp string locations of the series connection powered by a constant-current drive circuit, described lamp string location is by also
Multiple LED composition that connection connects.
As a kind of optimal way, described lamp string location is welding in parallel LED module in the circuit board.
Described wiring board is preferably PCB or FPC.
As another kind of optimal way, described lamp string location is that same intervals parallel connection is welded on two electric wires
LED.
As a kind of optimal way, two electric wires of described lamp string location welding can be separate two lists
Line, it is also possible to be a double doubling；The LED that described lamp string location uses is straight cutting or adopting surface mounted LED
Lamp bead.
As a kind of optimal way, the output electric current of described constant-current drive circuit, by described lamp string location
The rated current of LED and the quantity of LED determine, no more than LED quantity * LED rated current.
As a kind of optimal way, the output of described constant-current drive circuit, supply for described employing constant current
The general power of all LED in the LED string of electricity.
The method that the invention also discloses the LED string that two kinds of manufactures are welded on two electric wires.
One of which method comprises the steps:
1), two parallel electric wires are spaced strip off at correspondence position, form multiple pads arranged side by side；
2), it is sequentially inserted into the positive and negative pin of LED, LED at corresponding pad and is respectively inserted in two electric wires
Corresponding pad on, and welded；
3), by the LED quantity that each lamp string location is in parallel, the electric wire welding LED is disconnected, formed and separate
Unit；
4) electric wire one end of a polarity LED pin, using the first lamp string location is welded as input, first
Lamp string location welds the other end and the second lamp string location welding phase of another electric wire of another polarity LED pin
The electric wire of reversed polarity LED pin is electrically connected with, and the second lamp string location welds the electricity of another polarity LED pin
The electric wire of the other end of line and the 3rd lamp string location welding opposite polarity LED pin is electrically connected with, and connects successively
Connect formation one lamp string；
5) the multiple lamp string locations using length to intercept above-mentioned connection are pressed, by the first lamp string location when, using
Input be connected to a pole of constant-current drive circuit outfan, will in back light string location not with a upper lamp
The tail end of the electric wire that string location connects connects another of constant-current drive circuit outfan by another root electric wire
Pole.
Another kind of method comprises the steps:
1), two parallel electric wires are spaced strip off at correspondence position, form multiple pads arranged side by side；
2) the LED quantity, as required by each lamp string location, is sequentially inserted into LED at corresponding pad；
Wherein, the positive and negative pin of LED of same lamp string location is respectively inserted on the corresponding pad of two electric wires, phase
The positive and negative pin of LED of adjacent lamp string location is reversely inserted on the corresponding pad of two electric wires, and is welded；
3) the wherein disconnection in the electric wire of LED, next adjacent lamps string, by adjacent lamps string location are welded
The electric wire that unit disconnects is another root electric wire, makes adjacent lamps string location only have an electric wire to connect；
4) the multiple lamp string locations using length to intercept above-mentioned connection are pressed, by the first lamp string location when, using
In the head end of electric wire that is not connected with next lamp string location be connected to a pole of constant-current drive circuit outfan,
The tail end of the electric wire not being connected with a upper lamp string location in back light string location is connected by another root electric wire
Connect another pole of constant-current drive circuit outfan.
The present invention uses constant current-supplying, no matter the basic phase of electric current that lamp string how long, is added in each LED
With, so that the brightness of each LED luminescence is essentially identical；The present invention uses after multiple LED parallel connection again
No matter the frame mode of series connection, be used on decoration or composition contour line having have good effect, simultaneously
The present invention one or plurality of LEDs lamp damaged (short circuit or open circuit) therein are all without affecting Integral luminous
Performance；The present invention welds many group lamp string locations on two electric wires, whether by staggered after simple disconnection
Connect, or adjacent cells interlocks and disconnects the mode of wherein single line after welding, all makes the present invention have processing
Simply, low cost, variable-length, advantage that luminosity concordance is good so that the present invention has greatly
The market competitiveness.
