Abstract
The invention discloses a power driver cooling device of an LED (Light Emitting Diode) lamp, wherein the power driver cooling device can improve the working life of an electrolytic capacitor. The power driver cooling device of the LED lamp comprises a power driver. A cooling device is arranged on a circuit board of the power driver. The electric fan of the cooling device is arranged on the circuit board of the power driver. The electric fan faces to the electrolytic capacitor which is arranged in a power driver area. A positive pole and a negative pole which are led out from the circuit board of the power driver are serially connected with the capacitor and the electric fan. The capacitor is connected with a resistor in parallel. When the electrolytic capacitor works, heat produced by the electrolytic capacitor is taken away through the electric fan, the temperature of the electrolytic capacitor is decreased, the temperature of the electrolytic capacitor is ensured to be kept within a normal working temperature range, and the service life of the electrolytic capacitor is improved.
Description
Technical field
The present invention relates to the power drives of LED lamp, particularly the power drives heat sink of LED lamp.
Background technology
The power drives service life of LED lamp and the electrochemical capacitor in power drives have direct relation, and electrochemical capacitor its working life under different temperatures is widely different, and temperature is higher, and the life-span is shorter.Generally, the life-span of electric capacity shortens with the rising of temperature, is apparent that electrolytic capacitor most.Limit of working temperature is the electrolytic capacitor of 85 ℃, and while working under temperature is the condition of 20 ℃, ordinary circumstance can guarantee the normal working hours of 181019 hours; And while working under the condition of 85 ℃ of limiting temperatures, ordinary circumstance only can guarantee the normal working hours of 2000 hours.
Summary of the invention
The object of this invention is to provide a kind of power drives heat sink that can give improve the LED lamp of electrochemical capacitor working life.
Technical solution of the present invention completes like this, the power drives heat sink of LED lamp, it includes power drives, power drives wiring board is provided with heat sink, the electric fan of heat sink is located on power drives wiring board, electric fan is relative with the electrochemical capacitor being located in power drives district, and both positive and negative polarity and electric capacity, the electric fan of on power drives wiring board, drawing are cascaded, and electric capacity is together in parallel with a resistor.
Technique effect of the present invention is: electrochemical capacitor when work, heat electrochemical capacitor being produced by electric fan is taken away, and the temperature of electrochemical capacitor is reduced, and the temperature of guaranteeing electrochemical capacitor improves its use and receives the order within remaining on normal working temperature scope.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the circuit diagram of heat sink.
The specific embodiment
By reference to the accompanying drawings the present invention is described in further detail, on the wiring board 1 of power drives, establishes and should be electrically connected to, the both positive and negative polarity of heat sink and capacitor C, electric fan 2 are cascaded, and capacitor C and resistance R are connected in parallel; Electric fan 2 is relative with the electrochemical capacitor in power drives district, and the wind that electric fan 2 produces, to electrochemical capacitor, is lowered the temperature to the electrochemical capacitor in work, improves the working life of electrochemical capacitor.
