Abstract
The utility model relates to an illuminating device, in particular to a micro emergency lamp with the functions of a small night lamp. The utility model comprises a universal circuit of an emergency lamp, the universal circuit comprises a rechargeable battery BT connected with a relay J, the relay J is provided with a normally closed contact, the relay J and the rechargeable battery BT are respectively connected with an external power supply through an power supply plug; the rechargeable battery is connected with a LED lamp through the normally closed contact of the relay and a power switch K2, wherein, the rechargeable battery BT is also connected with the LED lamp through a switch K1 and a voltage-reducing resistor R6 that are parallelly connected with the relay J and the power switch K2, and the brightness of the small night lamp depends upon the resistance of the R6. The utility model has the functions of a small night lamp, has the advantages of simple structure and convenient operation.
Description
Technical field
The utility model relates to a kind of lighting apparatus, is specially a kind of miniature emergency light with the mini light night function.
Background technology
Emergency light is a kind of reserve ligthing paraphernalia that often uses in people's daily life, its universal circuit as shown in Figure 1, when being communicated with outside 220V electrical network, internal relay J gets electric and adhesive, the relay normally-closed contact is disconnected, thereby broken off the current supply circuit of battery BT to LED, LED can not be luminous; But externally under the situation of supply line's outage, the relay J of emergency light internal circuit discharges because of dead electricity, and battery BT powers to LED through normally-closed contact, power switch K2, the R5 of relay, thereby realizes the function of emergency lighting.But the setting of existing emergency light light is comparatively single, and light generally can't be regulated, and needs further improvement.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, easy to use at the comparatively single defective of existing emergency light light setting, the miniature emergency light of band mini light night function.
The technical solution of the utility model is as follows: a kind of miniature emergency light with the mini light night function, comprise an emergency light universal circuit, this universal circuit comprises the rechargeable battery BT that is connected with relay J, relay J is provided with normally-closed contact, relay J is connected with the externally fed power supply by attaching plug respectively with rechargeable battery BT, rechargeable battery is connected with the LED lamp by relay normally-closed contact, power switch K2, wherein, rechargeable battery BT also is connected with the LED lamp with dropping resistor R6 by the K switch 1 with relay J and power switch K2 parallel connection.
The utility model is inserted in the supply socket at ordinary times, when power supply has a power failure, can light automatically, realizes the function of emergency lighting.Under the normal situation of power supply,, the relay normally-closed contact is disconnected because relay J gets electric and adhesive, thereby broken off the current supply circuit of battery BT to LED, LED can not be luminous, at this moment, and Closing Switch K1, make circuit turn-on, because the hypotensive effect of dropping resistor, the light of LED lamp changes, and uses thereby can be used as mini light night, increased the function of emergency light, very easy to use.
Description of drawings
Fig. 1 is an emergency light universal circuit structural representation.
Fig. 2 is an electrical block diagram of the present utility model.
The specific embodiment
As shown in Figure 2, the miniature emergency light of band mini light night function comprises an emergency light universal circuit, the charging plug of this universal circuit is connected with the 220V supply socket, 220V voltage through the C1 step-down again after D1～D4 rectification, be divided into two-way, one the tunnel is added to the relay J two ends, because relay J gets electric and adhesive, the relay normally-closed contact is disconnected, relay J connects rechargeable battery BT, and rechargeable battery is by the relay normally-closed contact, power switch K2 is connected with the LED lamp, because the relay normally-closed contact disconnects, thereby broken off the current supply circuit of battery BT to LED, LED can not be luminous; Another Lu Zejing D5 charges to battery BT.When the 220V electrical network has a power failure suddenly, the voltage that is added in the relay J two ends disappears thereupon, relay J discharges because of dead electricity, and this moment, battery BT powered to LED through normally-closed contact, power switch K2, the R5 of relay, thereby has reached the purpose of grid power blackout automatic emergency lighting.
In addition, rechargeable battery BT also is connected with the LED lamp with dropping resistor R6 by the K switch 1 with relay J and power switch K2 parallel connection.Closure by direct gauge tap K1 makes circuit turn-on, because the hypotensive effect of dropping resistor, the light of LED lamp changes, and uses thereby can be used as mini light night.
If light fixture is pulled up from supply socket, be in normally off because of relay contact this moment, and the power supply of LED lamp work is provided by battery BT, strong, weak two kinds of duties that LED divides, the K2 that closes is a high light, and disconnecting the K2 K1 that closes again is the low light level, can reach the purpose of portable lighting very easily.
