Abstract

The utility model discloses a high-power double channel LED circuit, comprising a power supply, diodes, and light emitting diodes, wherein the light emitting diodes and the diodes are connected in parallel one-to-one, the light emitting diodes and the diodes are divided into two groups and 14 pairs, each pair is invertedly connected with the LED circuit in parallel, and the two groups are connected with the LED circuit in series. The LEDs are connected with the an inverted diode in parallel, such that even if one LED in the whole LED circuit is in a failure or is damaged, the rest can still normally work, and even if the current is overlarge, the brightness decay of the LEDs is not accelerated and the service life of the LEDs is not reduced, thereby greatly saving cost.

Description

High-power two-way led circuit
Technical field
The utility model relates to a kind of high-power LDE circuit, relates in particular to high-power two-way led circuit.
Background technology
What high-powered LED lamp inside was commonly used is series circuit; Series connection is that operating current is constant, and voltage changes, because high-power 1W LED and 3W LED are the electric currents of constant current 350mA and 700mA; Have only series connection could guarantee that the operating current of every LEDs is the same, could guarantee working life.
Series circuit has the people to be said if having gone bad other LED of LED has not all worked, but this probability is very low, the original LED quantity of high-power LED lamp just seldom, easy damage so not.
Aspect of parallel circuits considers it is reliable, if when having gone bad a LEDs, though the LED light fixture can also operate as normal; But the doomsday is not long; Because original normal operating current is to share on several LEDs, gone bad one now, the electric current of the hundreds of MA of his on one's body just is increased to other LED and gets on; The long-time high current work of other LED, the result only burns.
Present a lot of next lamp of situation do not work and cause a whole cluster of lamps, ornamental all not work, and cause the electric current of back to raise yet, and make LED light decay fast, and it is very big with waste to change such cost that spends to all LED again again.
The utility model content
Not enough the utility model according to above-mentioned technical problem provides a kind of high-power two-way led circuit.
In order to realize that the technical scheme that technique scheme the utility model proposes is high-power two-way led circuit, comprise power supply, diode, light-emitting diode, described light-emitting diode and diode are connected in parallel one to one.
Described light-emitting diode and diode have 2 groups 14 pairs, and every pair is connected in reverse parallel on the circuit, and 2 groups are connected on the circuit.
Described light-emitting diode is the above large-power light-emitting diodes of 1W.
Described electric power output voltage 48V, direct current 320mA.
This programme is high-power two-way led circuit; Such LED is bad or damage and can not cause the bad or cisco unity malfunction of a whole string LED; Can not occur because the excessive LED of the causing light decay of electric current is accelerated yet; Life-span shortens, and mainly is made up of LED and diode, when producing, only need on LED, get final product by parallelly connected again backward diode.
The beneficial effect of the utility model is: through on LED again backward diode of parallel connection make in the whole string led circuit LED bad or damage and can not cause the bad or cisco unity malfunction of a whole string LED; Can not occur because the excessive LED of the causing light decay of electric current is accelerated yet; Life-span shortens, and saves great amount of cost like this and also can not waste.
Description of drawings
Fig. 1 is the circuit structure diagram of the utility model.
Embodiment
To the utility model high-power two-way led circuit that elaborates, comprise power supply 1, diode 2, light-emitting diode 3 below in conjunction with Fig. 1, light-emitting diode 3 is connected in parallel with diode 2 one to one; Light-emitting diode 3 has 2 groups 14 pairs with diode 2; Every pair is connected in reverse parallel on the circuit, and 2 groups are connected on the circuit, and light-emitting diode 3 is the above large-power light-emitting diodes of 1W; Power supply 1 output voltage 48V, direct current 320mA.
Such LED is bad or damage and can not cause the bad or cisco unity malfunction of a whole string LED; Can not occur because the excessive LED of the causing light decay of electric current is accelerated yet; Life-span shortens, and mainly is made up of LED and diode, when producing, only need on LED, get final product by parallelly connected again backward diode.
Through on LED again backward diode of parallel connection make in the whole string led circuit LED bad or damage and can not cause the bad or cisco unity malfunction of a whole string LED; Can not occur because the excessive LED of the causing light decay of electric current is accelerated yet; Life-span shortens, and saves great amount of cost like this and also can not waste.
