Description

A dual-purpose LED lighting system for daily emergency

technical field

The utility model relates to the lighting field, in particular to a daily emergency dual-purpose LED lighting system.

Background technique

The current fire emergency lights are generally connected to the mains for charging, which is relatively wasteful of electric energy and not energy-saving enough. In addition, the current fire emergency lights do not work in normal times, and additional lamps need to be installed for lighting, which also causes a certain degree of waste of resources.

Contents of the invention

In order to solve the problems in the prior art, the utility model provides a dual-purpose LED lighting system for daily emergency, which can work in two states of daily lighting and emergency lighting according to the actual situation, saving resources.

The technical scheme that the utility model solves its technical problem adopts is:

A daily emergency dual-purpose LED lighting system, including an LED array and a driving circuit. The input end of the driving circuit is connected to the mains, and the output end is electrically connected to the LED array to supply power to the LED array. The lighting system also includes a lithium battery pack and a power supply. The charging circuit is connected to the driving circuit and the input end of the lithium battery pack, the output end of the lithium battery pack is electrically connected to the input end of the driving circuit, and is used to supply power to the driving circuit when there is no commercial power input.

Preferably, the LED array is composed of two groups of LED lamps, the two groups work simultaneously for daily lighting, and one group works for emergency lighting.

The beneficial effects of the utility model are:

1. When the mains power is normal, the lighting system charges the lithium battery pack through the driving circuit and the charging circuit. When the mains power is cut off, the lighting system can supply power to the driving circuit and the LED array through the lithium battery pack to achieve daily lighting and emergency Two working states of lighting;

2. The LED array is divided into two groups. When the system is powered by the mains, the two groups of LED lights work together for daily lighting. When the lithium battery pack is powered, the system only controls one group of LED lights to work, reducing system power consumption. Extend lighting hours.

detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Figure 1 is a schematic structural diagram of the utility model, as shown in the figure, the utility model provides a daily emergency dual-purpose LED lighting system, including an LED array 1 and a drive circuit 2, the input end of the drive circuit 2 is connected to the mains, The output end is electrically connected with the LED array 1 to supply power to the LED array 1. The lighting system also includes a lithium battery pack 3 and a charging circuit 4 for connecting the drive circuit 2 and the input end of the lithium battery pack 3. The output of the lithium battery pack 3 The terminal is electrically connected to the input terminal of the driving circuit 2, and is used for supplying power to the driving circuit 2 when there is no commercial power input. When the mains power is normal, the lighting system charges the lithium battery pack through the driving circuit and the charging circuit. a working state.

The LED array 1 is composed of two groups of LED lamps, the two groups work at the same time for daily lighting, and one group works for emergency lighting.

The parts not described in the description are prior art or common knowledge. This embodiment is only used to illustrate the utility model, and is not intended to limit the scope of the utility model. Those skilled in the art make modifications such as equivalent replacements to the utility model and all think that they fall into the protection of the utility model claims. within range.
