Abstract
The utility model discloses an LED emergency lamp which is characterized in that the utility model comprises an LED light source which is composed of LED arrays, the LED light source is connected with a main power supply and is connected with an emergency standby power supply, and an emergency automatic switchover circuit is connected between the main power supply and the emergency standby power supply. The utility model has the advantages of small size, high reliability, high efficiency, and long service life of a battery. The light source adopts energy-saving and high-effective LEDs, the emergency time is long, and the work reliability is high.
Description
Technical field:
The utility model relates to lighting technology, is a kind of special lighting, specifically a kind of LED emergency light.
Background technology:
For the purpose of safety, emergency light has been widely used in numerous occasions.Existing emergency light all is to adopt incandescent lamp or fluorescent lamp as light source usually, and by lead acid accumulator as emergency power supply.Such emergency luminaire, not only Zhao Ming brightness is very restricted, and volume is big, heaviness, useful life is short, and reliability is low, and the time of emergency lighting is also shorter.
Summary of the invention:
The purpose of this utility model provides that a kind of volume is little, good reliability, efficient height, battery life are long; Light source adopts the LED of efficient energy-saving, and the crash time is long, the LED emergency light that functional reliability is high.
Technical solution of the present utility model is: a kind of LED emergency light, it is characterized in that: the led light source that has led array to constitute, led light source is connected to main electricity, and is connected with emergency standby power, is connected to emergent automatic switch-over circuit between main electricity and spare emergent power source.
Main power supply circuits described in the utility model are made up of rectification circuit, the electronic transformer that is connected with rectification circuit, voltage stabilizing circuit.Emergency standby power is made up of nickel chromium triangle rechargeable battery pack and charging circuit.Emergent automatic switch-over circuit is a normally closed solid-state relay.Main power circuit is connected to the power supply status indicating circuit.
The beneficial effects of the utility model are: main electricity electronics transformer circuit, and volume is little, good reliability, efficient height; Charging circuit adopts integrated circuit, helps protecting battery, extending battery life; Light source adopts LED, and the crash time is long, the functional reliability height.The rated power scope is big, and is applied widely, do not wait from 4W-60W according to different size; Crash time can not waited from 90min-180min according to different size.
Below in conjunction with drawings and Examples the utility model is further described:
Description of drawings
Accompanying drawing is the circuit diagram of a kind of LED emergency light of the present utility model.
Embodiment:
Accompanying drawing has been described an embodiment of the present utility model, in this embodiment, the led light source that has led array to constitute, led light source is connected to main electricity, and be connected with emergency standby power, between main electricity and spare emergent power source, be connected to emergent automatic switch-over circuit.Described main power supply circuits are made up of rectification circuit (comprising rectifier diode D1, D2, D3, D4 etc.), the electronic transformer (being made up of diode D5, D6, D7, D8, D9, triode VT1, VT2, choke L2, L3, L4, L5, L6, capacitor C 11, C12, C13, C14, C15, resistance R 2 etc.), the voltage stabilizing circuit (comprising integrated package 7805 etc.) that are connected with rectification circuit.Emergency standby power is made up of nickel chromium triangle rechargeable battery pack (or other suitable similar rechargeable battery) and charging circuit (comprising integrated circuit AIC1563, diode D10, D11, D12, capacitor C 1, C2, C3, C31, C32, resistance R 10, R11, R13, R4, R5, choke L1 etc.).Emergent automatic switch-over circuit is a normally closed solid-state relay J.Main power circuit is connected to power supply status indicating circuit (comprising integrated circuit AIC1783, LED light, capacitor C 4, C9, C10, resistance R 6, R7, R8, R9, R14, R15, R16, triode Q1 etc.).Also have components and parts such as diode D13, resistance R 1, R3 in the circuit.
Operation principle: when civil power just often, charge inside circuit operate as normal is to rechargeable battery charging (when battery is full of, stopping automatically).After the civil power outage, emergency circuit switches, and battery is powered to LED, makes the luminous generation illuminating effect of LED.
