Abstract
The utility model discloses a light-emitting diode (LED) circuit control system with a fan cooling device, and the LED circuit control system relates to the technical field of the application of an LED on the aspect of street lamps. The LED circuit control system comprises a power supply, a constant-current source, a fan, a temperature detecting module and a control circuit; the power supply is connected with an LED lamp set through the constant-current source; a signal output end of the temperature detecting module is connected onto the control circuit; and an output end of the control circuit is connected with the fan. The LED circuit control system adopts the fan cooling device; after a lamp is electrified, the fan works according to an ambient temperature in the lamp, and when the temperature detecting module detects that a working ambient temperature in the lamp exceeds a set standard, the fan is enabled to begin working through the control circuit, so as to quicken air circulation and decrease the temperature. When the temperature detecting module detects that the working ambient temperature in the lamp is lower than the set standard, the control circuit enables the fan to stop working, so that the service life of the fan can be prolonged, and the electric energy is saved.
Description
Technical field
The utility model relates to LED applied technical field aspect street lamp.
Background technology
As everyone knows, in view of prior art, the advantage that the luminous original paper of LED has is that light efficiency is high, but, as not solving the problem of light decay, use LED as luminous original paper, particularly the great power LED luminescence component just can not demonstrate fully the advantage of the luminous original paper of LED.
At present, many light fixtures enterprise utilizes conventional lamp repacking LED light fixture, in order to overcome light decay; People mainly lean on the aluminium section bar radiator and adorn a fan and solve heat dissipation problem aspect heat radiation, have a bad place to be exactly the light fixture energized like this after, fan is just started working; Useful life of fan has been shortened in fan long-term work so greatly, also has now to the LED solar street light; The electric weight of battery stores just is not a lot, and the fan long-term work has also consumed a part of electric energy.In winter,, after lighting, light fixture there is no need to start the fan heat radiation, consumed power because outdoor environment is colder.
Summary of the invention
The utility model purpose is to design a kind of energy-conservation, as to be beneficial to the reduction light decay fan cooling apparatus used led circuit control system that has that is beneficial to.
The utility model comprises power supply, constant-current source, LED lamp group and fan; Said power supply is connected with LED lamp group through constant-current source; It is characterized in that also comprising temperature monitoring module and control circuit; The signal output part of said temperature monitoring module is connected on the control circuit, and the output of said control circuit is connected with fan.
The utility model adopts fan cooling apparatus used; Light fixture energising aft-fan when operating ambient temperature surpasses established standards in temperature detecting module detects light fixture, starts working fan through control circuit according to the ambient temperature work in the light fixture; Accelerate air circulation, reduce temperature.Operating ambient temperature is lower than established standards in temperature detecting module detects light fixture, and control circuit quits work fan, can prolong fan useful life and saves energy like this.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Embodiment
As shown in Figure 1, the utility model is provided with power supply 1, constant-current source 2, fan 3, temperature monitoring module 4, control circuit 5 and LED lamp group 6.
