Description
Technical field
This utility model is related to a kind of illuminating lamp, particularly a kind of LED street lamp driver.
Background technology
The power of LED street lamp is larger, and substantial amounts of heat can be produced in work, and heat can not be distributed in time, can cause LED core
Piece light decay accelerates, and PN junction burns out, and insulation ag(e)ing etc. has a strong impact on the service life of LED.Publication No. " CN105142272A "
Patent documentation disclose " a kind of radiating fault handling method of LED ", its technical scheme for adopting is：By in radiator
Upper increase temperature sensor, and increase electrical switch, after the temperature of radiator is too high, comparison circuit output switch in power end
Signal, electrical switch deenergization, LED quit work, and after temperature is reduced, electrical switch connects circuit, and LED recovers work
Make.This method can effectively extend the service life of product really, but as general whole LED only radiates with one
Device, after temperature is too high, electrical switch deenergization, whole LED extinguish, and illuminating effect, this way are just lost after extinguishing
It is infeasible in practice, particularly, the Temperature Distribution of whole LED lamp panel is uneven, and the high temperature of local is transmitted to scattered
After on hot device, heat is quickly transmitted on whole radiator, may cause the deficient change of temperature to cause electrical switch action,
Also LED street lamp damage is easily caused, and, the heat of LED lamp panel is transmitted on radiator and is also required to the regular hour, this side
Method thermometric has certain hysteresis quality, and temperature control effect is undesirable.
The content of the invention
In order to overcome the deficiencies in the prior art, this utility model provides one kind and can solve the problem that to be caused to use because of heat dissipation problem
The lost of life, there is provided the LED street lamp driver for persistently illuminating.
This utility model solves the technical scheme adopted by its technical problem：
A kind of LED street lamp driver, including driving power supply, the outfan of the driving power supply are parallel with some independent propping up
Road；The branch road includes LED lamp panel, temperature element, on-off circuit and comparator；The temperature element is arranged on the LED
On plate, the on-off circuit is serially connected on the line of LED lamp panel and driving power supply, a wherein input of the comparator and institute
State temperature element connection, another input termination reference amount, the output termination on-off circuit.
The beneficial effects of the utility model are：Each branch road of the present utility model is independent, wherein the temperature of a branch road
After exception, the signal trigger comparator of temperature element input, comparator send cut-off signals, and on-off circuit cuts off the branch road
Power supply, the branch road quit work, after temperature is reduced, the signal trigger comparator of temperature element input, and comparator sends leads
Messenger, on-off circuit connect the power supply of the branch road, and the branch road is resumed work, wherein a branch road or several branch road temperature
After exception, other branch road normal works are not interfered with, continuous illumination can be realized, and, point for measuring temperature is located in LED lamp panel, tool
Have the advantages that sensitivity is high, can effective protection LED chip, extend product service life.
Description of the drawings
With reference to the accompanying drawings and examples this utility model is further illustrated.
Fig. 1 is electrical block diagram of the present utility model.
Specific embodiment
With reference to Fig. 1, a kind of LED street lamp driver, including driving power supply 1, if the outfan of the driving power supply is parallel with
Dry independent branch road（In Fig. 1, dotted line frame show a branch road）；The branch road includes LED lamp panel 4, temperature element 5, switch electricity
Road 2 and comparator 3；The temperature element 5 is arranged in the LED lamp panel 4, the on-off circuit 2 be serially connected in LED lamp panel 4 with
On the line of driving power supply 1, a wherein input of the comparator 3 is connected with the temperature element 5, another input termination base
Quasi- reference quantity V, output terminate the on-off circuit 2.
The LED lamp panel 4 includes aluminium base 6 and the LED chip 7 being welded on aluminium base 6, and the temperature element 5 can be with
For temperature sensor, critesistor etc., the on-off circuit 2 can be miniature relay or by semiconductor device such as audion,
The electronic switching circuit of the compositions such as metal-oxide-semiconductor, temperature element 5 can be connected with the input "+" in the same direction of comparator 3, it is also possible to
The reverse input end "-" connection of comparator.The LED chip of wall scroll branch road can be series connection, or series connection is mixed with parallel connection
Connection, if the aluminium base plate suqare of wall scroll branch road is larger, can arrange several thermometric components and parts, one point for measuring temperature on aluminium base
Temperature exceed the upper limit after, you can trigger comparator cuts off the power supply of the branch road, after all points for measuring temperature less than connect after the upper limit should
The power supply of branch road.
Wherein after the temperature anomaly of a branch road, the signal trigger comparator of temperature element input, comparator send shut-off
Signal, on-off circuit cut off the power supply of the branch road, and the branch road quits work, after temperature is reduced, temperature element input
Signal trigger comparator, comparator send Continuity signal, and on-off circuit connects the power supply of the branch road, and the branch road recovers work
Make, as each branch road is independent, the power of LED street lamp is larger, and branch road quantity is more, wherein a branch road or several branch road temperature
After degree exception, other branch road normal works are not interfered with, continuous illumination can be realized, and, point for measuring temperature is located in LED lamp panel,
Have the advantages that sensitivity is high, can effective protection LED chip, extend product service life.
