Description
Technical field
The present invention relates to a kind of illuminating lamp, the illuminating useless power consumption of particularly a kind of daily life is zero AC 220 V semiconductor corridor road lamp.
Background technology
Existing corridor road lamp is used incandescent lamp, gas-filled lamp etc. always, and their weak point is: with under the constant power, their brightness is low, and power consumption is big, and the life-span is short, and the useless power consumption of their control circuit is also bigger.The weak point of existing LED integrated drive electronics is: the cost height, and power consumption, its useless power consumption is non-vanishing.
Summary of the invention
In order to overcome above-mentioned deficiency, the invention provides a kind of useless power consumption is zero AC 220 V semiconductor corridor road lamp.It is made up of lamp holder connector, lampshade, circuit installing plate, semiconductor LED array and led drive circuit.It is characterized in that
Be packaged with led drive circuit in the described lamp holder connector; Described lampshade is fixed on the lamp holder connector; Described lampshade below is fixed with the circuit installing plate; Be evenly distributed with many high-brightness semiconductor led array on the described circuit installing plate; Described led drive circuit is by the step-down current-limiting circuit, rectification circuit, and transient protection, filter circuit are formed; The ac input end of described rectification circuit is in series with the step-down current-limiting circuit that is made of electric capacity; The dc output end of described rectification circuit is parallel with transient protection, filter capacitor and semiconductor LED array.
The hickey that described lamp holder connector is a standard or the hanging interface of standard.
Described circuit installing plate be plane or the spherical calotte type.
Described semiconductor LED array is connected in series by many high-brightness semiconductor LED or semiconductor LED chip or LED paster and forms.
Described rectification circuit is made up of the rectifier bridge that four diodes constitute.
Compared with prior art, the invention has the beneficial effects as follows: (one), the semiconductor LED volume is little, in light weight, the life-span is long, luminous efficiency is high, energy-conservation, the electricity consumption of a corridor road lamp of the present invention only is equivalent to the electricity consumption of present corridor road lamp controller.(2), drive circuit is simple, its useless power consumption is zero, the reliability height, cost is low, makes simple.(3), the LED stabilized intensity, the flicker free sense.(4), since entire circuit be capacitive, help improving the power factor (PF) of AC network, pollution-free to AC network.Helping absorbing the pollution of AC network, is Environmental protection lamp.
Description of drawings
Fig. 1 is a drive circuit schematic diagram of the present invention.
In Fig. 1,1. alternating current 220V input, 2. electric capacity 1,3. rectifier bridge, 4. electric capacity 2, the 5.LED array.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is elaborated.
In circuit shown in Figure 1, useless power consumption be the drive circuit of zero AC 220 V semiconductor corridor road lamp by step-down current limiting capacitance (2), rectification circuit (3), filter capacitor (4) and led array (5) composition.The ac input end of rectification circuit (3) is in series with electric capacity (2); The led array (5) that the dc output end of rectification circuit (3) is parallel with electric capacity (4) and is in series by semiconductor LED.The rectifier bridge that rectification circuit (3) is made of four diodes.Useless power consumption is that the reduction voltage circuit of zero AC 220 V semiconductor corridor road lamp drive circuit adopts high-voltage capacitance (2); alternating current 220V is become low pressure output; after rectifier bridge (3) rectification, obtain direct current; after transient protection, filter capacitor (4) filtering, obtain DC current more stably again, give high-brightness semiconductor led array (5) power supply.When disturbing, the voltage at electric capacity (4) two ends can not suddenly change, and has protected the operate as normal of semiconductor LED array (5).Semiconductor LED array (5) is connected in series by many high-brightness semiconductor LED or semiconductor LED chip or LED paster and forms.Because drive circuit of the present invention does not use dissipative cell, so the useless power consumption of AC 220 V semiconductor corridor road lamp of the present invention is zero.
