[specific embodiment]

Shown in Fig. 1 to 5, a kind of emergent indicator lamp comprises a box body 1 with opening 2, and box body 1 comprises base 11 and the lid 12 that is buckled on the base 11, and base 11, lid 12 surround the box body, and box body two ends are connected with end cap 14 by screw 13 lockings.

Acrylic show label board 3 is equipped with at opening 2 places, wiring board 10, rechargeable battery 4 is housed in the box body 1, adopt first group of LED5 of extraneous power supply power supply, adopt second group of LED6 of rechargeable battery 4 power supplies, behind extraneous power cut-off, automatically switch to rechargeable battery 4 and give the control circuit board 7 of second group of LED6 power supply and the glue box 15 of dress rechargeable battery 4 and control circuit board 7, first group of LED 5, LED crown portion on second group of LED6 is towards the opening 2 of box body 1, LED on LED on first group of LED 5 and the second group of LED6 is staggered on wiring board 10, and control circuit board 7 is connected with by lead and is used for the binding post 71 that is connected with extraneous power supply and extraneous power supply is converted to the converter 8 of giving rechargeable battery 4 chargings after the low tension.

In the utility model, converter 8 is a transformer, and converter 8 is connected between binding post 71 and the control circuit board 7.When electrical network had electricity, control circuit board 7 provided the pulsation charge circuit for rechargeable battery 4, and the interchange after converter 8 transformations becomes the direct current of pulsation through the D7 rectification, was rechargeable battery 4 chargings again after the R14 current limliting.

The utility model course of work is as follows: when electrical network had electricity, control circuit board 7 was first group of LED5 power supply, by the illumination of first group of LED5, makes the luminous demonstration of sign on the show label board 3, and control circuit board 7 is rechargeable battery 4 chargings simultaneously; And when having a power failure, control circuit board 7 transfers rechargeable battery 4 automatically to and gives second group of LED6 power supply, it is constant to guarantee to adopt the 3 luminous demonstrations of show label board, not only power consumption is little for this emergent indicator lamp that adopts LED to illuminate show label board 3, economic environmental protection, two groups of LED switch makes the indicator lamp long service life, and display brightness height when uniform a plurality of LED are luminous on first group of LED5, the second group of LED6, the elderly also easily sees sign clearly on remote, practical.

For ease of whether can operate as normal in detection system, do not pull out simultaneously extraneous binding post 71 power lugs again, in the utility model, also be connected with the button 91 and the signal lamp 92 that are used for testing circuit plate Circuits System on the control circuit board 7, button 91 and signal lamp 92 are installed on box body 1 one end caps 14.Under the energising situation, first group of LED5 is bright, push button 91, control circuit board 7 automatically switches to rechargeable battery 4 and gives second group of LED6 power supply, and this moment is bright as signal lamp 92, second group of LED6, first group of LED5 extinguishes that to show that then circuit connects correct, release button, then first group of LED5 is bright, and second group of LED6 and signal lamp 92 extinguish, simple in structure, convenient and practical.
