Description

Light-operated light timing device

The utility model relates to a kind of timing device of being made up of light-sensitive element.Being particularly suitable for those darknesses turns on light and does not need bright lighting system engineering to daybreak.

In the prior art, directly control the lighting fixture of Push And Release, in navigation light, be applied by light-sensitive element.But it can not use the most of occasion as neon light, advertising lamp box, street lamp, at present the most widely used commercially available timer representative products of this type of light engineering.As: the quartzy time switch of SDK-2 type that the KG316T microcomputer time switch that the American-European gram in Zhuhai Special Zone Instr Ltd. produces and Shanghai Electric Clock Factory produce, this timer of controlling Push And Release fully with the time, in order to follow the tracks of the trouble that the time difference in the four seasons brings is to set up lighting time frequently, and the user uses very inconvenient; Also to add a rain control protective device when this time switch is used in as neon light in addition, increase many expenses.

The purpose of this utility model be to provide a kind of melt light-operatedly turn on light, time control is turned off the light, the multi-functional timing device of rain control protection three unification.

1, by light-operated circuit and the time control circuit light-operated light timing device that constitutes jointly, photodiode D ₃With capacitor C ₂Polyphone is connected across between power supply VCC and the ground resistance R ₅Be connected their mid point B and triode V ₂Become the input of first reverser between the B utmost point, resistance R ₄, D ₂, V ₂The tie point of the C utmost point is V ₂Output be again the second reverser V ₁Input, D ₃Be subjected to light to be low-resistance, B point high level, A point low level, V ₁End J ₁No current passes through, and is in contrast unglazed, C ₁And C ₂Be attempted by between A, B point and the ground, because C ₁, C ₂Discharge and recharge D ₃Whether short time is subjected to light, and A, B point high level can not suddenly change, and it is characterized in that: D ₃Unglazed one to three minute, B point low level, A point high level, J ₁There is electric current to pass through J1-2, D ₅, R ₁₃, D ₈, C ₄Be serially connected between VCC and ground, D, E point is set up high level fast; J1-2, D ₅, R ₁₃, R18, D ₁₁, C ₅Be serially connected between VCC and ground, because R ₁₈Resistance is much larger than R ₁₃, by the V11CE utmost point, D ₁₂, C ₅Be serially connected between VCC and ground R ₁₉, D ₁₀Polyphone is connected on their input, and the accelerating circuit of composition makes the G point only keep 30 seconds low levels, jumps to high level R ₂₀Be serially connected in G point and V ₁₀The B interpolar, V ₁₀, V ₉Conducting, D point low level, D ₈Instead end partially, by C ₄E point high level is kept in discharge, by C ₅G point high level D point low level is kept in discharge; F point alarm clock pulse control V ₈End V ₇The time of conducting is greater than by C ₄Keep the time of E point high level.

Two, confine delay circuit (prolonging circuit): J hereinafter to be referred as frame _1-2, D ₅(indication at night), R ₁₃, D ₈, C ₄For frame prolongs first loop; R ₁₄, V ₅, V ₆, R ₁₂, D ₇For frame prolongs second loop.When changeing night from daytime, J ₁Adhesive, J _1-2Closure, the power supply VCC frame of flowing through prolongs the C in first loop ₄Momentary charge; Meanwhile, frame prolongs the second loop input and gets high level, V ₅, V ₆Conducting, D ₇The anode low level is instead ended partially, J in the C point low level main control loop ₂Discharge, normally-closed contact is connected the external loading loop, finishes night and turns on light.And begin simultaneously to carry out and confine time-delay, suitably select C ₄Capacity, R ₁₄Resistance, V ₅, V ₆The β value, can roughly time-delay be confined in the regular hour scope, accurate timing, the technical finesse difficulty is bigger.Generally time-delay is confined in the long time, for example 5-8 hour, to satisfy the usefulness of precision timing.
