Integral device of cold light emergency light and coldlight exit panel

Abstract

An integrated device of cold light emergence lamp and cold light exit indication plate lamp is prepared as setting multiple sockets on centralized control box for socketing multi-set power supply plugs of emergency lamp and exit indication plate lamp, forming said control box by said multiple sockets, cell, micro control chip for detecting cell on fixed time and cold light element driving circuit for carrying out drive under control of said chip.

Description

technical field [0001] The invention relates to an emergency lighting device, in particular to an integrated device of a cold light emergency light and a cold light exit sign which integrates lighting and indicating functions. Background technique [0002] Fire emergency lights and emergency exit signs are widely used in commercial, industrial and civil buildings. They are necessary fire-fighting devices for each building, and both emergency lights and emergency exit signs are indispensable and must be used together. However, these two devices mostly exist as two separate and independent devices at present, and there are many following deficiencies in their design: [0003] 1. As shown in Figure 1, traditional emergency lights generally use incandescent bulbs as their light source, so they have the disadvantages of high current, short life, light scattering and low brightness. In order to meet the emergency lighting time requirements of fire regulations, sealed lead-acid ba...

AI Technical Summary

Problems solved by technology

Such batteries are heavy and bulky, thus burdening the load-bearing capacity of buildings

In addition, the internal space of existing buildings is very limited, and the corresponding products occupy a large space, which brings inconvenience to the internal layout of the building.

Moreover, the reliability of this type of battery is low, the price is high, and the corresponding product cost is high, and the service life is generally only one to two years.

[0004] 2. As shown in Figure 2, the traditional exit display board has its own power supply and drive circuit, which makes the device heavy and noisy, which increases the cost and is not conducive to installation

Because the transformer itself is also heavy and bulky, the overall weight and volume of the emergency lights and emergency exit signs increase, so its manufacturing cost is high

[0006] 4. The traditional emergency exit signs and emergency lights belong to two independent devices

[0010] In a nutshell, in the prior art, when the emergency exit sign and the emergency light exist as two separate and independent devices, the emergency exit sign and the emergency light need to have their own power supply and drive circuit respectively, resulting in a heavy and heavy device. There is noise, which increases the cost and is not conducive to installation

In addition, the integrated emergency exit signs and emergency lights are inseparable from each other, and each integrated emergency exit sign and emergency light also has its own power supply and drive circuit, which also makes the device heavy and noisy. It increases the cost and is not conducive to installation

In addition, because the existing emergency exit signs and emergency lights use incandescent bulbs, lead-acid batteries, and transformer technology, it will inevitably bring about the disadvantages mentioned above
