[0002] As we all know, ceiling lights are widely used in homes and other places because they are easy to install. However, the ceiling lights on the market are currently limited in style and function, and generally only have lighting function. Since they rely on mains power for lighting, they cannot provide emergency lighting when there is a sudden power outage or when the power is suddenly cut off in case of an emergency. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art by providing a ceiling light with an emergency power supply. In the event of a power outage, the emergency power supply can power the lamp panel and also provide illumination.

[0004] The technical solution of this utility model is as follows: A ceiling light with an emergency power supply includes a lamp holder and a lamp cover detachably connected to the lamp holder. The lamp holder contains a lamp plate and a driving power supply. The lamp plate is connected to the driving power supply. The lamp holder also contains an emergency power supply box located inside the lamp plate. The emergency power supply box contains an emergency circuit board and a battery connected to the emergency circuit board. The emergency circuit board is connected to the driving power supply.

[0005] Using the above technical solution, the driver power supply is connected to an external power line. During normal use, the driver power supply supplies power to the lamp board. In the event of a power outage, the emergency circuit board will automatically switch to battery power supply mode and start the emergency power supply. The battery supplies power to the driver power supply through the emergency circuit board, thereby providing power to the lamp board. It can be used for 3-5 hours.

[0006] A further feature of this invention is that the emergency power supply box is detachably connected to the lamp holder. One of the lamp holder and the emergency power supply box is provided with a mounting block, and the other is provided with a corresponding mounting groove. The mounting block is located in the mounting groove to realize the installation of the emergency power supply box.

[0007] With the above-mentioned further settings, the installation and positioning are accurate, and the emergency power supply box can be quickly and accurately installed on the lamp holder.

[0008] A further feature of this invention is that the lamp holder is also provided with a locking member for locking the emergency power supply box inside the lamp holder. The locking member is rotatably disposed inside the lamp holder and has an unlocked position and a locked position. When the locking member is in the unlocked position, the side of the locking member is located at one end of the emergency power supply box, and the emergency power supply box can slide axially relative to the lamp holder. When the locking member is in the locked position, the locking member is pressed against the emergency power supply box to restrict the axial sliding of the emergency power supply box.

[0009] With the above-mentioned further design, the emergency power box is locked to the lamp holder by a locking component, which makes the emergency power box structure stable, but does not affect the disassembly of the emergency power box. Unlocking or locking can be completed simply by rotating the locking component, which is convenient and quick to operate and disassemble.

[0010] A further feature of this invention is that: an installation shaft is provided at one end of the emergency power supply box inside the lamp holder, and the locking member is rotated and mounted on the installation shaft, with the locking member being arranged in a "D" shape.

[0011] The above-mentioned further design makes the locking mechanism more stable and better locks the emergency power box. When the locking mechanism is rotated and the vertical part of the locking mechanism faces the emergency power box, the vertical part is located at one end of the emergency power box. At this time, the locking mechanism is in the unlocked position, and the emergency power box can be disassembled and assembled. When the locking mechanism is rotated in the opposite direction, the arc part of the locking mechanism presses against the emergency power box, and it cannot be disassembled at this time. The structure is simple and the operation is convenient.

[0012] A further feature of this invention is that the locking member is provided with a driving block that drives it to rotate around the mounting shaft, and the lamp holder is provided with limiting members located on both sides of the mounting shaft to limit the rotation angle of the driving block. The two limiting members are separated from the mounting shaft to form an active space for the locking member to rotate.

[0013] With the above-mentioned further design, the drive block is easier for users to operate, the drive locking component is easier to rotate, and the limit component can limit the rotation angle of the locking component to prevent it from being too large and affecting the disassembly and assembly of the emergency power supply box.

[0014] A further feature of this invention is that the outer wall of the locking member is provided with an outwardly protruding positioning block. When the locking member is in the unlocked position, the positioning block abuts against one of the limiting members. When the locking member is in the locked position, the positioning block abuts against the other limiting member. The outer side of the positioning block and the limiting member facing each other is arc-shaped.

[0015] By adopting the above-mentioned further settings, the locking component can be positioned so that the structure is stable whether it is in the unlocked or locked position. The locking component will only rotate when the user drives it. Especially when it is in the locked position, the positioning component can also cooperate with the drive block to improve the stability of the locking component and make the locking effect better.

[0016] A further feature of this invention is that the emergency power supply box includes a first box and a second box that are separately configured. The emergency circuit board is installed in the first box and the battery is installed in the second box. The first box is provided with a connection slot, and the second box is provided with a connector. The connector is inserted into the connection slot to connect the two boxes.

[0017] By adopting the above-mentioned further design, heat accumulation is avoided. The batteries are placed in their respective boxes to effectively isolate the heat, prevent overheating, extend battery life, and isolate the batteries from the emergency circuit board to prevent leakage liquid from damaging the emergency circuit board. This effectively prevents the circuit board from being affected by moisture, dust, or overheating, ensuring the stability and lifespan of the circuit. Attached Figure Description

The power supply box 5 contains an emergency circuit board 51 and a battery connected to the emergency circuit board 51. The emergency circuit board 51 is connected to the driving power supply 4, which is connected to an external power line. During normal use, the driving power supply 4 supplies power to the lamp board 3. In the event of a power outage, the emergency circuit board 51 will automatically switch to battery power mode and start the emergency power supply. The battery supplies power to the driving power supply 4 through the emergency circuit board 51, thereby providing power to the lamp board 3. It can be used for 3-5 hours. After normal power is restored, it can also charge the battery to store power for the next emergency lighting.

[0032] The lamp holder 1 is also equipped with a locking member 6 for locking the emergency power box 5 inside the lamp holder 1. The locking member 6 is rotatably disposed inside the lamp holder 1 and has an unlocked position and a locked position. When the locking member 6 is in the unlocked position, its side is located at one end of the emergency power box 5, and the emergency power box 5 can slide axially relative to the lamp holder 1. When the locking member 6 is in the locked position, it presses against the emergency power box 5 to restrict the axial sliding of the emergency power box 5. The emergency power box 5 is locked to the lamp holder 1 by the locking member 6, making the structure of the emergency power box 5 stable, but without affecting the disassembly of the emergency power box 5, which can be completed by simply rotating the locking member 6. The locking and unlocking mechanism is easy to operate and quick to assemble and disassemble. The lamp holder 1 has an installation shaft 11 located at one end of the emergency power box 5. The locking element 6 is rotated and mounted on the installation shaft 11. The locking element 6 is D-shaped, which makes the structure of the locking element 6 stable and better locks the emergency power box 5. When the locking element 6 is rotated and the vertical part of the locking element 6 faces the emergency power box 5, the vertical part is located at one end of the emergency power box 5. At this time, the locking element 6 is in the unlocked position, and the emergency power box 5 can be disassembled and assembled. Reverse rotation of the locking element 6 causes the arc-shaped part of the locking element 6 to press against the emergency power box 5, making it impossible to disassemble. The structure is simple and the operation is convenient.

[0033] The locking member 6 is provided with a driving block 61 that drives it to rotate around the mounting shaft 11. The lamp holder 1 has limiting members 12 located on both sides of the mounting shaft 11 to limit the rotation angle of the driving block 61. The two limiting members 12 are spaced apart from the mounting shaft 11 to form a space for the locking member 6 to rotate. The driving block 61 is easy for the user to operate, and it requires less effort to drive the locking member 6 to rotate. The limiting members 12 can limit the rotation angle of the locking member 6, preventing it from rotating too much and affecting the disassembly and assembly of the emergency power box 5. The outer wall of the locking member 6 is also provided with an outwardly protruding positioning block 62. When the locking component 6 is in the unlocked position, the positioning block 62 abuts against one of the limiting components 12. When the locking component 6 is in the locked position, the positioning block 62 abuts against the other limiting component 12. The outer side of the positioning block 62 facing the limiting component 12 is arc-shaped, which can position the locking component 6, making it structurally stable whether it is in the unlocked or locked position. The locking component 6 will only rotate when the user drives it to rotate. Especially when it is in the locked position, the positioning component can also cooperate with the driving block 61 to improve the stability of the locking component 6 and make the locking effect better.

[0034] The emergency power box 5 is detachably connected to the lamp holder 1.
