Abstract
A street lamp power saver relates to a circuit device which controls a lighting lamp by using a semiconductor device. When the existing street lamp is used at night, the power and the lighting load are reduced, the power supply voltage is increased, on one hand, the electric energy is wasted, and on the other hand, the street lamp is accelerated to age. The utility model discloses to the above-mentioned shortcoming of current street lamp, propose with the automatic device that reduces voltage of thyristor, utilize photo resistance, the automatic break-make voltage of light projector simultaneously, saved the manual management street lamp. The utility model discloses low in manufacturing cost, simple and convenient reliable, the economize on electricity effect is very obvious, is suitable for cities and towns, the street lamp economizes on electricity of factory and mines to use.
Description
Title of the present utility model is an electronic power saver for street lamp, relates to using the circuit arrangement that semiconductor device is controlled illuminating lamp.
Existing cities and towns and after factories and miness street lighting every day 23.00, because power and electric consumption on lighting load reduce, illuminalive power-supply voltage raises, generally all more than 230V to 240V.Wasted electric energy so on the one hand, on the other hand because the rated voltage of general lighting lamp is 220V, overtension makes the aging quickening of illuminating lamp, and the life-span shortens.In addition, transitional street lamps is dark in the sky, during daybreak, need artificial break-make power supply, can not automatically switch.
The purpose of this utility model is to overcome the above-mentioned shortcoming that existing illuminating lamp exists, and proposes a kind of electronic power saver for street lamp that utilizes controllable silicon to reduce too high voltages, utilizes photo resistance to realize auto switching to street lamp simultaneously.
Below in conjunction with accompanying drawing the present utility model purpose is realized elaborating:

pIt is high resistive that resistance is, and is in full conducting between solid-state relay KS5.6 pin, and street lamp RL is bright entirely.R
3With R
1Parallel connection guarantees the conducting of thyristor full voltage, and during to 23:00, electric contact quartz clock normally closed contact S disconnects, and makes the phase shift of thyristor triggering signal, reduces V
1The angle of flow makes V
1R is adjusted in step-down output
wMake the L.N terminal voltage be output as street lamp low-voltage power supply voltage.(be the bright back of a street lamp street lamp power supply, road lamp power supply average voltage that records during this period of time half an hour to 22.) up to second day at day, because illumination increases, the RP resistance is low resistance JCG parameter solid-state relay open circuit, street lamp R
LLamp goes out.
As street lamp R
LDuring for incandescent lamp, directly get final product,,, when exchanging in the week electric voltage dropping 5%, can cause after put out, putting out certainly just to rekindle in 3～5 minutes because these two kinds of lamps have relatively high expectations to supply power voltage if when street lamp is high-pressure mercury-vapor lamp or sodium vapor lamp with this circuit.Electric voltage dropping problem when solving 23:00 should add the common delay circuit of a cover at circuit, to guarantee bulb unlikely extinguishing in the step-down process.
Fig. 2 is the schematic diagram of light projector.
In order to increase RP photo resistance sensitivity, designed a small-sized light projector, R
pPut on this light projector focus.This light projector is made by the R=50mm concave mirror, and focus A B to the limit is
=25mm is R
pBe placed on the A point, can improve its sensitivity greatly.R
pTwo ends be associated in 3.4 bipods of circuit solid-state relay KS respectively.Light projector can only be put to the back, burns out R otherwise easily focused on by sunlight

Fig. 3 is the structure chart of electronic power saver for street lamp.1-light projector wherein, 2-electric power quartz clock.3-shell, 4-solid-state relay, 5-printed circuit board (PCB).This electricity-saving appliance is installed in public lighting circuit switch-box downside, and bidirectional thyristor seals in the street lamp major loop.
The parameter of components and parts is as follows:
S: be the quartzy electric power timing controller of SPK-2 type normally-closed contact.KS:JCG parameter solid-state relay.RP: photo resistance, bright resistance≤IK Ω, resistance in the dark 〉=IM Ω, 1 peace.V
2: the heavy time variant voltage＞400V of thyristor off-state, what electric current is electric current＞1.5～2 times maximum bear.R
2：75Ω。R
1: 20K Ω, R
w: 0～10K Ω is adjustable.C3：0.33uf。The electricity-saving appliance operating voltage is 220V, and operating current is respectively 10A, 20A, 30A, 50A, 100A, 150A, 200A, 300A, 500A
Compare with existing illuminating lamp electricity consumption, use electronic power saver for street lamp, economize on electricity is remarkable: with 250W10 lamp calculates, 1 year 2250 degree that can economize on electricity, and economize on electricity takes 562.5 yuan, have more than is needed half a year With regard to recoverable investment. Simultaneously, 23 are reduced later on too high supply voltage, greatly improve bulb and reach The service life of fluorescent tube. Manpower has then been saved in the power supply of automatic switchover illuminator. China's one annual electricity generating capacity Be 9,000 hundred million degree, electric consumption on lighting accounts for more than 5%, therefore promotes the use of electronic power saver for street lamp economy effect Benefit is very huge.
