Description
Technical field
The utility model relates to a kind of light-emitting diode (LED) energy-saving lamp that human induction switch is arranged.
Background technology
The present lighting that human induction switch is arranged, general fluorescent lamp that all adopts the high pressure excitation and osram lamp are as light emitting source, under the situation of the frequent induction of human body, control circuit can frequently be exported high level/low level control signal, because the inherent characteristic of fluorescent lamp and osram lamp, under the situation of frequent energising and pass electricity, can shorten greatly the useful life of its light emitting source, must often change fluorescent tube; Simultaneously, during the circuit starting, must provide bigger electric current and higher starting resistor, so power consumption is very high.
Summary of the invention
The purpose of this utility model provides a kind of energy-efficient, long-life energy-saving lamp that human induction switch is arranged.The purpose of this utility model is achieved like this: the utility model is made up of power supply, control power supply and lamp plate assembly and shell mechanism: described power supply is to adopt prior art, and the direct voltage of operate as normal is provided for light-emitting diode; Described control power supply is to adopt prior art, for the human body induction module switch in the lamp plate assembly provides low pressure galvanic current source; Described lamp plate assembly by the human body induction module switch in the prior art, wiring board and a plurality of/(or) individual unit circuit series connection current limliting adjusts resistance and forms; The individual unit circuit is by the identical light-emitting diode of a plurality of performances (LED) series connection, and a plurality of element circuits can be formed in parallel by the individual unit circuit; Described light-emitting diode (LED) is adjusted resistance through current limliting, and two ends are connected on respectively between supply voltage and the ground wire.When ambient light illumination less than setting, and under the situation of human body sensing, power supply can be exported the direct voltage of setting, and through current-limiting resistance, the operating current of regulation is provided to light-emitting diode, thereby make the light-emitting diode forward conduction and send white light, after the output delay time of setting finished, light fixture extinguished automatically.
The utility model because LED has the characteristic of high frequency break-make, adopts LED as light emitting source in this circuit, and cooperates the human body induction module switch, thereby have energy-efficient compared with the prior art. feature of long life.
Description of drawings
Fig. 1 is the circuit diagram of a kind of embodiment of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the embodiment of accompanying drawing, but be not to limit scope of the present utility model by any way.
As shown in Figure 1, the utility model is made up of power panel 1, lamp plate assembly 2.
The lamp plate assembly 2 of present embodiment is adjusted resistance C by existing human body induction module switch 3 and individual unit circuit D series connection current limliting and is formed.
Single or multiple element circuit D of the present utility model generally is made up of 43-159 the identical LED of performance: when LED quantity is less than 50, can adopt as shown in Figure 1 individual unit circuit D--by the identical LED series connection of a plurality of performances; When LED quantity greater than 50, then adopt individual unit circuit D parallel connection as shown in Figure 1.The utility model little power consumption, for example: the light emitting source of being made up of 43 LED is when operate as normal, and available power only is 4 watts.
The described power panel 1 of present embodiment is made up of power supply 4 and control power supply 5 two parts; its adopts be have high-temperature resistant output capacitor, wide power be input as 110V-250V, soft start electric current (reduce exchange input impact), efficient greater than 80%, shock-resistant electric current, leakage current be less than 1ma/240V, and has the existing high-effect driving and the people of overvoltage overload protection function to feel automatic control power supply.
Human body induction module switch 3 provides power supply by power panel 1, when ambient light illumination less than setting, and under the situation of human body sensing, the high level that human body induction module output is about 3 volts, effect through the control power supply in the power panel 1, make the direct current supply voltage of power supply output regulation, for the LED light emitting source provides normal working voltage.The duration of human body induction module switch output high level is by the design document regulation of product, behind the delay time that surpasses regulation, the human body induction module switch can be automatically converted to low level, effect through the control power supply, cut off the supply power voltage of light emitting source, thereby light emitting source is extinguished, when receive the human-induced signal next time, then repeat said process.
During the light-emitting diode operate as normal, must guarantee the size of its operating current, general value is 15-25ma (milliampere), and electric current is excessive or too small, all can influence the useful life of light-emitting diode, thereby influences reliability of products.In the present embodiment circuit, power supply adopts the resistance-capacitance depressurization circuit, and the size of light-emitting diode operating current determines that by the amount of capacity of electric capacity in the present embodiment, the operating current of light-emitting diode is 20ma (milliampere).
Because the frequent switch of human body induction module switch, and light emitting source is light-emitting diode (LED), therefore, is necessary for light-emitting diode the safeguard measure that prevents overvoltage and overcurrent is provided.In the present embodiment, install suitable piezo-resistance additional, utilize piezo-resistance to absorb the characteristic of high pressure and anti-surge, thereby reach the purpose of overvoltage protection at the output of power supply.The pressure sensitive voltage value (V) of piezo-resistance is determined by following formula: the series connection quantity of V=3.4x light-emitting diode.
