Description

Technical Field

Background

In life, a problem often occurs, for example, when a user goes back to a room to sleep, the user needs to turn off the light, and after the user faces that the user needs to turn off the light, the user needs to go back to the room in a dark state, which is inconvenient. The switch control needs wiring, which is inconvenient for many places where wiring is already done, the cost is high for remote control, and the operation is troublesome because the switch control needs matching. The delay control is relatively low in cost and convenient to operate, but the problem is that the schemes are not solved, for example, in some underdeveloped areas, the power supply of the underdeveloped areas is insufficient, and power is frequently cut off, so that the underdeveloped areas need a lamp capable of illuminating after power failure; in addition, the lamp can automatically perform emergency after power failure, but has no function of time delay light turning off. If the functions of lamp turning-off delay and emergency lighting are needed, two LED lighting lamps are bought, one with the lamp turning-off delay function and the other with the emergency lighting function, so that the cost is high, and the practicability of installing two lamps in one room is poor.

When the energy storage module 150 receives the discharging signal, it supplies power to the LED load 120, and when the energy storage module 150 receives the non-discharging signal, it does not supply power to the LED load 120.

Further, the delay detection control module 130 is configured to send a discharge signal to the energy storage module 120 when the commercial power is powered, the LED load 120 is turned from the on state to the off state, and the emergency detection control module 140 does not enter the emergency state, so that the LED load can be continuously turned on, the lighting time may be between 5 seconds and 60 seconds, and the specific time may also be adjusted according to the requirements of the customer. Otherwise, the delay detection control module 130 sends a non-discharge signal to the energy storage module 150. In one embodiment, the delay detection control module may be a commercially available product, such as a chip with model number ME2816 or KU 5590.

Further, the emergency detection control module 140 is configured to send a discharge signal to the energy storage module 150 when the commercial power fails and the LED load 120 is in a light-on state; otherwise, the emergency detection control module sends a non-discharge signal to the energy storage module 150. The emergency detection control module 140 may also select some mature products in the market, such as a chip with model number SP 1691.

Further, the delay detection control module 130 and the emergency detection control module 140 may also be an integrated chip integrating the delay detection control function and the emergency detection control function, such as a chip with model number SP 1693.

The working principle of the emergency working state and the light-off delay working state is as follows:

A. when the commercial power is electrified and the lamp is turned on, the voltages of the live line L and the zero line N are very high, and at the moment, the emergency detection control module can detect that the LED lamp is normally used without starting emergency lighting, so that a non-discharge signal is provided for the energy storage module through the signal line S4.

B. When the commercial power is powered off, the voltage between the live wire L and the zero wire N is zero, and the two wires are in a high-impedance state, so when the emergency detection control module detects that the live wire L and the zero wire N have no voltage and the two wires are in the high-impedance state, the emergency detection control module can give a non-discharge signal to the energy storage module through the signal wire S4 and does not enter emergency lighting.

C. When the commercial power is cut off in a light-off state, the voltage between the live wire L and the zero line N is zero, and the two lines belong to a high-impedance state, so when the module of the emergency detection control module detects that the voltage between the live wire L and the zero line N is zero and the two lines belong to the high-impedance state, the emergency detection control module can give a non-discharge signal to the energy storage module through the signal wire S4 and does not enter emergency lighting.

D. When the commercial power is in a state of switching on the lamp in the power failure, the voltage between the live wire L and the zero wire N is zero, and the two wires belong to a low-resistance state, so when the emergency detection control module detects that the voltage between the live wire L and the zero wire N is zero, and the two wires belong to a low-resistance state or a two-wire short circuit, the emergency detection control module can provide a discharging signal for the energy storage module through the signal wire S4 to discharge the energy storage module, the energy storage module provides energy for an LED load through the L2 and the N2, and then emergency lighting is started.

E. When the commercial power is powered on and the lamp is turned on, the delay detection control module detects that the LED driving power supply works normally through S1; at this time, the lamp is turned off, the delay detection control module detects that the LED driving power supply stops working through S1, and the delay detection control module detects that the emergency detection control module does not enter the emergency state through S2. The delay detection control module will give a discharging signal to the energy storage module through S4 to discharge the energy storage module, so that the LED lamp can be continuously turned on for 5-60 seconds, and the specific time can be adjusted according to the requirements of the customer.

F. When the commercial power is powered on and the lamp is turned on, the delay detection control module detects that the LED driving power supply works normally through S1; at this time, if power is suddenly cut off, the delay detection control module detects that the LED driving power supply stops working through S1, and the delay detection control module detects that the module of the emergency detection control module enters an emergency state through S2, then the delay state is cancelled, and the emergency lighting state is directly entered.

The foregoing is a more detailed description of the present application in connection with specific embodiments thereof, and it is not intended that the present application be limited to the specific embodiments thereof. It will be apparent to those skilled in the art from this disclosure that many more simple derivations or substitutions can be made without departing from the spirit of the disclosure.
