The controller 5 is fixed in the middle of the chassis 8, the emergency light source 6 and the high-power light source 61 are respectively fixed on the chassis 8, and the chassis 8 is made of iron materials, so that the heat dissipation effect of the light source can be achieved. The chassis is provided with a battery compartment 54 for placing the rechargeable battery 51, and protecting the rechargeable battery 51 from damage. The ac mains supply supplies power to the controller 5, and the power module 1 converts ac power into dc power, which supplies power to the control system, and also charges the rechargeable battery 51. The control unit 3 is electrically connected to the emergency light source 6, the photosensitive module 4 and the light source driving module 31, and the light source driving module 31 is electrically connected to the high-power light source 61.

When alternating current exists, the power module 1 converts the alternating current into direct current to supply power to the control unit 3, the human body induction module 2, the light source driving module 31 and the high-power light source 61, and simultaneously charges the rechargeable battery 51 if the rechargeable battery 51 is under-voltage. At this time, if the human body sensing module 2 senses the presence of a human body, it will output a control signal to the control unit 3, the control unit 3 outputs a PWM signal to the light source driving module 31, the light source driving module 31 will drive the high power light source 61 to be turned on, and the brightness is 100%. After 20 seconds, if the human body sensing module 2 does not sense a person, the control unit 3 controls the light source driving module 31 to reduce the brightness of the high-power light source 61 through the PWM signal, and adjusts the brightness of the high-power light source 61 to 50%, so that the aim of saving electric energy can be achieved without blackening a piece of paint in the corridor, and a better experience is provided for the user, wherein the brightness adjustment to 50% is only an illustration of the embodiment, and certainly, as long as the brightness is lower than 100%, the utility model also belongs to the protection scope of the utility model.

When the alternating current is powered off, the power module 1 detects that the alternating current is disconnected, and at the moment, the power module 1 can automatically switch to the rechargeable battery 51 to supply power, and the rechargeable battery 51 supplies power to the control unit 3, the human body induction module 2 and the emergency light source 6. Since it is not suitable to supply the high-power light source 61 in consideration of the battery power supply, only the emergency light source 6 is operated in order to extend the power supply use period when the rechargeable battery 51 is supplied with power. Similarly, when the human body sensing module 2 senses the existence of a human body, a control signal is output to the control unit 3, and the control unit 3 outputs a PWM signal to the emergency light source 6, so that the emergency light source 6 is turned on and the brightness is 100%. After 20 seconds, if the human body sensing module 2 does not sense a human body, the control unit 3 controls the brightness of the emergency light source 6 to be 50% through the PWM signal, so as to achieve the purpose of saving electric energy, wherein the brightness of 50% is only an example of the embodiment, and certainly, only the brightness is lower than 100%, which also belongs to the protection scope of the present utility model. Particularly, when a fire disaster or other hazards occur in a public area, the power failure of the area can be caused, and the induction lamp can be powered by the built-in rechargeable battery 51 to continuously provide illumination, so that emergency illumination is provided for evacuees, and a vital function is played.

The utility model is also internally provided with a switch, and the switch can be switched into an automatic induction on-off mode through a toggle switch. That is, if the human body sensing module 2 senses the existence of a human body, it will output a control signal to the control unit 3, the control unit 3 outputs a PWM signal to the light source driving module 31, the light source driving module 31 will drive the high-power light source 61 to be turned on, and the brightness is 100%. After 20 seconds, if the human body sensing module 2 does not sense a human body, the control unit 3 controls the light source driving module 31 to turn off the high-power light source 61 through the PWM signal, so as to realize the function of automatically sensing on and off.

Further, the top of the battery compartment 54 is provided with a battery compartment upper cover 52, the bottom of the battery compartment 54 is provided with a battery compartment heat dissipation hole 53, a lithium battery is selected as a rechargeable battery, the rechargeable battery 51 is placed in the battery compartment 54, the battery compartment 54 is protected from being damaged by high temperature, the battery compartment 54 is far away from the high-power light source 61, damage to the rechargeable battery 51 due to temperature is reduced, and the service life of the rechargeable battery 51 is prolonged. The power module 1 is switched to a rechargeable battery 51 to provide emergency power for the controller 5 after the ac power is cut off.

Further, since the power of the emergency light source 6 is smaller, the emergency light source 6 can be controlled to be turned on by directly outputting the PWM signal through the control unit 3. Since the high-power light source 61 has a large power, the control unit 3 cannot directly drive the high-power light source 61, and thus the high-power light source 61 needs to be controlled to be turned on by the light source driving module 31, and the control unit 3 directly drives the light source driving module 31 to control the high-power light source 61.

Further, the emergency light source 6 has a small number of lamp beads and a small power, and therefore generates very little heat, and is fixed to the inner ring of the chassis 8. The high-power light source 61 has a large number of beads and a large power, and therefore generates a very large amount of heat, and is fixed to the outer ring of the chassis 8, and is away from the rechargeable battery 51, thereby avoiding damage to the rechargeable battery 51.

Further, the human body sensing module 2 is a human body pyroelectric sensor or a microwave radar sensor. The human body induction module 2 of this embodiment adopts a microwave radar sensor, the output end of the human body induction module 2 is electrically connected with the input end of the control unit 3, and when the human body induction module 2 senses a person, the control unit 3 is triggered to output a PWM signal to control the on and off of the high-power light source 61 and the emergency light source 6.

Further, the photosensitive module 4 is a photosensitive sensor, and an output end of the photosensitive module is electrically connected with an input end of the control unit 3, and is used for detecting the brightness degree of the external environment, when the brightness of the external environment is higher than a threshold value, the control unit 3 does not work, that is, the human body induction module 2 inducts that a human body cannot turn on a light source. When the external environment brightness is lower than the threshold value, the control unit 3 starts to work, and after the human body sensing module 2 senses a human body, the human body sensing module 2 triggers the control unit 3 to output a control signal, so that the human body sensing lamp does not work in daytime, and only works when the environment is dark, thereby achieving the purpose of saving electric energy.
