Description

A kind of emergent electricity-saving lamp

Technical field

The utility model belongs to a kind of lighting apparatus, the emergent electricity-saving lamp of particularly a kind of LED, fluorescent lamp combination.

Background technology

Traditional fluorescent lamp is good illumination effect under the Alternating Current Power Supply situation, but as with its emergency light of making, because input is big with the output pressure drop, it is very low that efficient becomes, and operable time is short, in order to prolong power-on time, have to use jumbo battery or the fluorescent tube derate is used, thereby make the emergency light volume big, the cost height, and the emergency light done of common energy-saving fluorescent lamp since when using fluorescent tube often be operated in and be lower than under its rated power situation, fluorescent tube is rapidly aging.And use LED as emergency light, and existing structure is such: constitutes by battery, charging and discharging control circuit and LED lamp group, and the LED emergency light of this form, because the defective of LED illuminator itself, optically focused is too concentrated, uncomfortable cooperation general lighting uses.

Summary of the invention

The utility model mainly solves the shortcoming of the described existing emergency light of background, invent a kind of merge LED and common power saving fluorescent lamp advantage emergent electricity-saving lamp, improve luminous efficiency, save electric energy, extend working time.

The utility model contains LED lamp group 2, circuit drives plate 4, rechargeable battery 5, lamp socket 6, lamp housing 7, light cover 8, circuit drives plate 4, rechargeable battery 5 all are arranged in the lamp housing 7, LED lamp group 2 is arranged on the light cover 8, be loaded with charging circuit 41, emergency circuit 42 on the circuit drives plate 4, this circuit drives plate 4 is electrically connected by electric wire 3c, 3b, 3d respectively with lamp socket 6, LED lamp group 2, rechargeable battery 5.It is characterized in that: also be provided with energy-saving fluorescent lamp 1 on light cover, and circuit drives plate 4 is the circuit boards that contain charging circuit 41, emergency circuit 42 and electronic rectifier circuit 43, described circuit drives plate 4 is electrically connected by electric wire 3a with energy-saving fluorescent lamp 1.

Emergency light of the present utility model, be to use alternating current to energy-saving fluorescent lamp 1 power supply in the occasion that alternating current is arranged, simultaneously to built-in rechargeable battery 5 chargings, when running into power-off condition, energy-saving fluorescent lamp 1 extinguishes, and LED lamp group 2 starts automatically as emergency lighting, collection illumination and emergent and one, can save emergency circuit, the convenient installation.And the life-span of fluorescent lamp is guaranteed.In addition, because the LED light efficiency is than electricity-saving lamp height, so can guarantee the power supply of longer time.The utility model has merged the advantage of LED and two kinds of illuminators of energy-saving fluorescent lamp like this, and two kinds of illuminators cooperatively interact, and remedy shortcoming separately, reach the balance of power saving and illuminating effect, and simple in structure, volume is small and exquisite.

The specific embodiment

According to shown in Figure 1, should comprise energy-saving fluorescent lamp 1 by anxious electricity-saving lamp, LED illumination group, track link (3a, 3b, 3c, 3d, circuit drives plate 4, rechargeable battery 5, lamp socket 6, lamp housing 7, light cover 8.Described circuit drives plate 4, rechargeable battery 5 all are arranged in the lamp housing 7, energy-saving fluorescent lamp 1, LED illumination group 2 all are arranged on the described light cover 8, and the circuit drives plate is electrically connected by electric wire 3a, 3b, 3c, 3d respectively with lamp socket 6, energy-saving fluorescent lamp 1, LED illumination group 2, rechargeable battery 5 with 4.

As shown in Figure 2, contain charging circuit 41, emergency circuit 42 and electronic rectifier circuit 43 on the circuit drives plate 4, circuit drives plate 4 connects rechargeable battery 5, energy-saving fluorescent lamp 1 and LED lamp group 2 respectively.

An embodiment of the drive circuit of circuit drives plate as shown in Figure 3: the on-off circuit that LED lamp group constitutes by switching tube Q3, resistance R 7, R8 and capacitor C 7 and D7, D8, and cooperate switch SW 1-1 to control current switching, this part power supply is introduced from the both positive and negative polarity of rechargeable battery, simultaneously, charging inlet AC input links to each other with said switching circuit with bridge circuit BR2 by the resistance-capacitance depressurization circuit that resistance R 6, capacitor C 6 constitute, and also can charge to rechargeable battery.

In addition, charging inlet AC input inserts the fluorescent tube rectification circuit by switch SW 1-2 with power supply, is used for driving fluorescent tube.Concrete circuit is: switch SW 1-2 back is behind bridge circuit BR1, and the amplifying circuit that constitutes via Q1, Q2 and resistor-capacitor unit is connected to inductance W1, W2, W3 again, forms ballast circuit, and to the fluorescent tube power supply, capacitor C 5 is connected in parallel on the fluorescent tube 1.

Switch SW is two sections switches, and SW1-1 and SW1-2 are its two sections, can control the break-make of two parts circuit respectively.

The utility model emergency light duty is such:

1, be in switch SW and disconnect and have under the alternating current AC electric power thus supplied, the interchange input of circuit of fluorescent lamp electronic ballast and the output of battery all are cut off, therefore energy-saving fluorescent lamp 1 and LED lamp group 2 all do not work, and alternating current is by the C6 step-down, then by after the bridge heap BR2 rectification rechargeable battery being charged;

2, be under the closed Alternating Current Power Supply situation simultaneously in switch SW, energy-saving fluorescent lamp 1 is lighted by electric ballast, by the C6 step-down, charging circuit by bridge heap BR2 rectification charges to rechargeable battery 5 then, and the emergency loop of being made up of R8, D7, D8, Q3 is controlled the output of rechargeable battery 5 simultaneously, and this moment, Q3 was in cut-off state, thereby cut off the output of rechargeable battery 5, LED lamp group 2 does not work;

3, be in closure and under the situation about having a power failure at switch, Q3 becomes conducting by ending, 2 discharges of 5 pairs of LED lamps of rechargeable battery group, LED lamp group 2 enters illumination condition, and the emergency lighting state occurs, this moment is owing to the brightness meeting when voltage ratio is low of LED lamp group 2 obviously reduces, can remind the user to turn off this lamp immediately, avoid battery to cross and put, increase the service life of rechargeable battery 5;

4, switch disconnects under the while power-off condition, and can not charge can not bright lamp.
