Abstract
The invention discloses an economical emergency LED (light-emitting diode) lamp which comprises a housing, an LED lamp bar driving circuit, an LED lamp bar, and a change-over switch and a socket which are arranged in the housing, wherein a first stationary contact of the change-over switch is connected with an output end of the LED lamp bar driving circuit; a second stationary contact of the change-over switch is connected with the output end of the LED lamp bar driving circuit by the socket; and a movable contact of the change-over switch is connected with a power supply input end of an LED lamp tube. According to the economical emergency LED lamp, the change-over switch and the emergency socket are additionally mounted in the LED lamp tube, and a port externally provided with an emergency power supply is additionally formed in the LED lamp tube with a normal function, so that common illumination and low-light-level emergency illumination functions are realized, the convenience of the LED lamp tube is kept, the possibility of transforming the LED lamp tube into an emergency lamp is provided, the economy of emergency illumination is achieved, and an application of the LED lamp is more extensive.
Description
Technical field
The present invention relates to a kind of LED lamp, relate in particular to a kind of economical emergency LED lamp.
Background technology
The LED lighting engineering is the important content of present world lighting field develop rapidly, and the LED lamp substitutes the trend of common fluorescent lamp and also strengthens day by day.Because the drive circuit of LED fluorescent tube is built in LED fluorescent tube inside, in daily use, directly insert the 220V power supply in lamp tube ends, and do not need to be connected in series ballast etc., very convenient.But when emergency lighting is used, present technology can not suitably reduce the brightness of light fixture by the method for external control, therefore need to be equipped with the battery pack of larger capacity usually, realize emergency lighting with this, but this kind mode not only external device is huge, and the cost in the practical application exceeds several times than general fluorescent tube emergency lighting, the cost height, take up room greatly, not attractive in appearance, be not suitable for large tracts of land and promote.
Summary of the invention
The purpose of this invention is to provide low, the little economical emergency LED lamp that takes up room of a kind of cost, change between civil power and the emergency power supply fast in the time of can making things convenient for emergency lighting and switch.
The present invention adopts following technical proposals:
A kind of economical emergency LED lamp, comprise housing, LED lamp bar drive circuit and LED lamp bar, also comprise the change-over switch and the socket that are arranged in the housing, first stationary contact of described change-over switch connects the output of LED lamp bar drive circuit, second stationary contact is by the output of socket connection LED lamp bar drive circuit, and the movable contact of described change-over switch connects LED tube power input.
Described socket is the four-core socket.
Described change-over switch is the DPDT change-over switch.
The present invention has increased the interface of external emergency power supply by installing change-over switch and emergency sooket additional in LED fluorescent tube inside at the LED of normal function fluorescent tube.When the LED lamp uses as normal illumination, switch is placed the normal position, this moment, the function of LED fluorescent tube was the same as the original.When as general lighting and emergent the use, switch is placed emergency position, insert emergent interface with emergency power supply unit this moment, namely realize the convenience of general lighting and low-light (level) function of emergency illumination, maintenance LED fluorescent tube, for transforming the emergent lamp that uses as, the LED fluorescent tube provides possibility again, reached the economy of emergency lighting, it is more extensive to make the LED lamp use.
Description of drawings
Fig. 1 is mounting structure schematic diagram of the present invention;
Fig. 2 is electrical block diagram of the present invention.
The specific embodiment
As shown in Figure 1, a kind of economical emergency LED lamp, comprise housing 4, LED lamp bar drive circuit 2 and LED lamp bar 5, also comprise the DPDT change-over switch 3 and the socket 1 that are arranged in the housing 4, first stationary contact of described change-over switch connects the output of LED lamp bar drive circuit 2, and the input of LED lamp bar drive circuit 2 is electrically connected with the city.Second stationary contact is by the output of socket 1 connection LED lamp bar drive circuit 2, and the movable contact of described change-over switch connects the power input of LED fluorescent tube.Described socket 1 is four-core socket 1.
The present invention adds DPDT change-over switch 3 and four-core socket 1 between drive circuit in original LED tube circuit and the lamp bar.This DPDT change-over switch 3 and 1 combination of four-core socket is as a whole, be built in the housing 4 of LED lamp.
When the civil power normal power supply, DPDT change-over switch 3 is placed the normal position, among Fig. 2, double-point double-throw switch is stirred left, provide 24V(or 36V by LED lamp bar drive circuit 2 for LED lamp bar 5) low-voltage dc power supply, 5 work of driving LED lamp bar, use with common LED illuminating lamp the same for normal illumination this moment.External power source through inverter to batteries charging.The function of LED fluorescent tube is the same as the original.
This device also can be used for emergency light to be used, need the supply unit by four-core socket 1 external emergency light this moment, DPDT change-over switch 3 is stirred to the right when placing emergency position then, then can be realized two kinds of functions of general lighting and low-light (level) function of emergency illumination.When the externally fed fault, LED lamp bar drive circuit 2 quits work, this moment, emergency power supply unit started, battery pack is exported 24V(or 36V by inverter to LED lamp bar 5) low-voltage dc power supply, current characteristics according to LED, this moment control inverter output current, both can realize that little electric current lighted LED lamp bar 5.The input power of LED lamp bar 5 is controlled by inverter at this moment, has therefore reached the purpose that realizes the emergency lighting of LED fluorescent tube with less battery capacity, thereby has realized the economy of emergency LED fluorescent tube.
Emergency power supply unit of the present invention is made up of rechargeable battery and inverter, can design according to different needs, and described inverter concrete structure no longer specifically describes.
The present invention passes through at the built-in change-over switch of existing LED lamp and socket 1, do not change under the prerequisite of existing LED lamp size, make the LED lamp can make things convenient for external emergency power supply unit, and behind the collocation emergency power supply unit, also make the existing many Battery packs emergency lighting miniaturization of volume ratio of whole emergency light, and can realize the illumination of low-light level, namely play the emergency lighting effect, and save electric power resource.
