Abstract
The invention relates to a large-power light emitting diode (LED) strip-shaped structure energy-saving lamp, which comprises an aluminum shell, a heat conduction aluminum substrate, a luminous diode and a high frequency transformer, wherein alternative current (AC) 200V high-frequency power supply is inputted from the input end of the high frequency transformer, alternative current (AC) 36V power is outputted from the output end of the high frequency transformer, then the AC power is converted to direct-current power through a bridge-type rectifier consisting of the diode, the direct-current power which is rectified through an electrolysis capacitor is filtered, then the direct-current power is limited through a sensor to obtain the rated 320mA current needed by the large-power diode, and the current is connected with the luminous diode through the aluminum substrate so as to realize the illumination.
Description
Technical field
The invention belongs to a kind of decorating lighting lamp, relate to a kind of high-power LED light source energy-saving lamp.
Background technology
The LED wall lamp is again line style LED Projecting Lamp etc., because its profile strip, also having the people that it is called the LED line lamp, mainly is to do a building decoration illumination usefulness, is used in addition sketching the contours the profile of heavy construction, traditional prior art is all with power supply of single one meter configuration, it is divided into two classes by control mode, and one is constant voltage source, and two are the crossing current power supply, manufacture process bothers relatively, and use is the not easy-maintaining that damages.So make attendant's workload increase, the numerous prices of the similar LED light fixture of existing market kind are also relatively costly, the security of using at product and all process imperfection on the short problem service life of product, can not be fully and lifetime of LED be complementary, lack a kind of deficiencies such as power supply of long service life.
Summary of the invention
The object of the invention is, for the deficiencies in the prior art, proposes a kind of high-power LED bar structure energy-saving lamp.
High-power LED bar structure energy-saving lamp of the present invention, comprise aluminium type shell, the heat conduction aluminum substrate, light emitting diode and high frequency transformer, it is characterized in that: by the input of high frequency transformer (1), input AC200V high frequency electric source, the output of high frequency transformer (1), the alternating current of output low pressure AC36V, the bridge rectifier (2) that consists of through diode again changes direct current into, carry out filtering for rectification direct current out by electrochemical capacitor (4), DC current through filtering carries out current limliting to inductor (3), obtain the required 320 milliamperes specified electric current warp of heavy-duty diode, aluminium base (5) is connected to light emitting diode (6) and realizes illumination.
The present invention's beneficial effect compared with prior art: with respect to the circular configuration of LED Projecting Lamp, the heat abstractor of the strip structure of LED wall lamp seems that better processing a bit
Description of drawings
The invention will be further described below in conjunction with accompanying drawing, but embodiments of the present invention are not limited to this.
Fig. 1-technical scheme circuit diagram
Among the figure: high frequency transformer (1), bridge rectifier (2), inductor (3), electrochemical capacitor (4), aluminium base (5), led light source (6).
The specific embodiment
As shown in Figure 1: high-power LED bar structure energy-saving lamp of the present invention is comprised of four parts: high frequency transformer, rectifying and wave-filtering, current-limiting inductance and load light emitting diode.High frequency transformer provides specified power voltage and electric current for load, consists of full-wave rectifier filter with fast recovery diode and electrochemical capacitor and becomes direct current, and DC voltage provides 320 milliamperes of electric current powering loads through current-limiting inductance.Load is connected by 12 pearls, and power is that the light emitting diode of single 1W consists of; It comprises aluminium type shell, the heat conduction aluminum substrate, light emitting diode and high frequency transformer, it is characterized in that: by the input of high frequency transformer (1), input AC200V high frequency electric source, the output of high frequency transformer (1), the alternating current of output low pressure AC36V, the bridge rectifier (2) that consists of through diode again changes direct current into, carry out filtering for rectification direct current out by electrochemical capacitor (4), the DC current of process filtering carries out current limliting to inductor (3) and with the impact that prevents high-frequency impulse load is consisted of infringement, required 320 milliamperes specified electric current is connected to light emitting diode (6) through aluminium base (5) thereby the inductance energising forms magnetic resistance acquisition heavy-duty diode, LED light emitting diode mean allocation voltage by a plurality of series connection, rated voltage when being the work of diode, thus realize illuminated area.This light fixture cooperates magnetic current limit by inductance element few owing to adopting the high frequency transformer power supply, and stability is high.Its element is magnetic device, and the probability of damage seldom reaches the effect of long-term use.Because device reaches the effect of long-term use less.Because device largely reduces product bug less, manufacture simple, from the cost calculation of power material than 10 times at original end.
Claims (1)
1. high-power LED bar structure energy-saving lamp, comprise aluminium type shell, the heat conduction aluminum substrate, light emitting diode and high frequency transformer, it is characterized in that: by the input of high frequency transformer 1, input AC200V high frequency electric source, the output of high frequency transformer 1, the alternating current of output low pressure AC36V, the bridge rectifier 2 that consists of through diode again changes direct current into, carry out filtering for rectification direct current out by electrochemical capacitor 4, DC current through filtering carries out current limliting to inductor 3, obtain the required 320 milliamperes specified electric current of heavy-duty diode, be connected to light emitting diode 6 and realize illumination through aluminium base 5.
