LED connection circuits.
The utility model also provides a kind of LED lamp.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of LED connections circuit, including LED, micro-control unit MCU, Microcontroller Unit and LED driving
Circuit, LED drive circuit one end connection signal input terminal, the other end connect LED, and the MCU is for providing pulse signal
To LED drive circuit, the LED drive circuit is used to pulse signal being conveyed to LED, for controlling the opening and closing of LED.
The LED is more than two concatenated LED lamp beads.
The utility model also provides a kind of LED lamp, including above-mentioned LED connection circuits.
The LED lamp is LED worklight, LED automobile lamps and lanterns or LED wall wash lamp.
Compared with prior art, the utility model reduces the time that LED is lighted, and the junction temperature of LED is reduced, on illuminating effect
Equivalent prior art.Using the LED connection circuits of the utility model, the service life of LED improves 20-30%.
Description of the drawings
Fig. 1 is the circuit catenation principle figure of LED connections circuit provided by the utility model.
In figure：1-LED, 2- micro-control unit MCU (Microcontroller Unit), 3-LED driving circuits.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings, but not as the restriction to the utility model.
Referring to Fig. 1, a kind of LED connections circuit, including LED1, MCU2 and LED drive circuit 3,3 one end of LED drive circuit
Connection signal input terminal, the other end connect LED1, and micro-control unit MCU (Microcontroller Unit) 2 is for providing arteries and veins
Signal is rushed to LED drive circuit 3, LED drive circuit 3 is used to pulse signal being conveyed to LED1, for controlling the unlatching of LED1
And closing.
The applying frequency of the utility model MCU micro-control units (Microcontroller Unit) is in 900HZ-
1100HZ, pulse duty factor 50%；
The pulse signal Fast transforms of the utility model, living human eye's None- identified, actual scene illumination application with it is existing
Scheme illuminating effect is identical, but the utility model reduces the duty ratio that LED is used, and reduces LED operation time 20-50%.Prolong
Long LED service life is 20%. or more.
The LED of the utility model can be as needed, the more than two concatenated LED lamp beads of setting in the line.
The utility model also provides a kind of LED lamp, including above-mentioned LED connection circuits.
The LED lamp of the utility model can be that LED worklight, LED automobile lamps and lanterns or LED wall wash lamp etc. are a variety of with LED
For the lamps and lanterns of light source.
In Fig. 1 of the utility model, VIN is signal input part, and the service life of LED is improved using the utility model,
It reduces and replaces the frequency.Reduce enterprise, businessman, individual estimated cost.
Embodiment described above, only one kind of the utility model more preferably specific implementation mode, the skill of this field
The usual variations and alternatives that art personnel carry out within the scope of technical solutions of the utility model should all be included in the guarantor of the utility model
It protects in range.
