Description

Technical Field

[0001] The present application relates to the technical field of lighting equipment, and in particular to a dual-power ceiling lamp. Background Art

[0002] Lamps are a general term for lighting tools, usually referring to devices that can transmit light, distribute and change the distribution of light sources, including all parts required to fix and protect the light source in addition to the light source, as well as the wiring accessories necessary for connecting to the power supply. Lamps can be divided into chandeliers, table lamps, wall lamps, floor lamps and other forms.

[0003] In order to prevent sudden power outages, an independent power supply needs to be set in the lamp. When the power supply system fails and a power outage occurs, the independent power supply set in the lamp supplies power to the lamp so that it can illuminate normally. However, the independent power supply set in the lamp may be damaged or forgotten to be charged during use, resulting in the lamp being unable to be used normally in the event of a failure.

The second heat sink 11 is connected with an emergency controller 15 and a driving power supply 16, and the emergency controller 15 is electrically connected to the two emergency power supplies 14 at the same time.

[0039] Reference Figure 1 , Figure 5 and Figure 6, the ventilation assembly 5 is arranged on the electric control box 1, and the ventilation assembly 5 includes a heat dissipation fan 51, a ventilation elbow 52, ​​a dust cover 53 and a temperature sensor 54. Several heat dissipation fans 51 are connected to the electric control box 1, and the air outlet end of the heat dissipation fan 51 is arranged toward the inner cavity of the electric control box 1. A vent 106 is provided on the vertical side wall of the electric control box 1, and the ventilation elbow 52 is fixedly connected to the vertical side wall of the electric control box 1 and is connected to the vent 106. The ventilation elbow 52 is arranged in a U shape, and the dust cover 53 is connected to the open end of the ventilation elbow 52 by a hinge rotation.

Several temperature sensors 54 are connected at different positions in the inner cavity of the electric control box 1, and several temperature sensors 54 are electrically connected to the heat dissipation fan 51.

[0040] Reference Figure 1 and Figure 7 The heat dissipation assembly 6 is arranged on the light installation board 4, and the heat dissipation assembly 6 includes a cooling plate 61, a liquid storage tank 62, a first connecting pipe 63, a second connecting pipe 64 and a circulation pump 65.

[0041] Reference Figure 5 In a normal use environment, the driving power supply 16 is connected to an external power line (not shown in the attached figure) to provide power for the lamp, and the external power line passes through the box body 101 through the wiring hole 103 set on the electric control box 1. When an external power outage or a fault is detected, the emergency controller 15 switches to the emergency power supply 14 to power the lamp, ensuring the normal use of the lamp in the event of a fault. When one set of emergency power supplies 14 is used up or fails, the emergency controller 15 controls the switching of another set of emergency power supplies 14 to supply power, reliably ensuring the normal operation of the lighting equipment. In addition, without turning off the lamp, the two emergency power supplies 14 can be periodically charged and discharged through the emergency controller 15, which helps to extend the service life of the lamp.

[0042] Reference Figure 2 , Figure 3 and Figure 6The sealing ring groove 22 and the dustproof sealing ring 8 improve the connection tightness between the lampshade 2 and the mounting lamp board 4, and reduce the possibility of dust and impurities in the external environment entering the lampshade 2 through the gap to affect its lighting brightness. The temperature sensors 54 arranged at different positions in the electric control box 1 detect the temperature in the electric control box 1 at the same time. When the temperature exceeds the set threshold, the cooling fan 51 starts to blow air into the electric control box 1 to cool it down. When the airflow passes through the vent 106 and the ventilation elbow 52 and blows out of the electric control box 1, the dustproof cover 53 rotates under the action of the airflow and moves away from the open end of the ventilation elbow 52. After the airflow stops, the dustproof cover 53 rotates to the open end of the ventilation elbow 52 again under the action of gravity to block it. The setting of the dustproof cover 53 reduces the possibility of external impurities entering the electric control box 1. The setting of the ventilation elbow 52 allows a small part of the external impurities to be deposited in its lowest pipe section, further reducing the possibility of external impurities entering the electric control box 1.

[0043] Reference Figure 2 and Figure 5 The first heat sink 10 and the second heat sink 11 are provided to dissipate heat for the emergency power supply 14, the wiring terminal 12, the driving power supply 16 and the emergency controller 15, thereby reducing the possibility of overheating during use. During loading and unloading, the electric control box 1 can be connected and disassembled by simply opening the end cover 102 and inserting the first heat sink 10 and the second heat sink 11 between the corresponding plug strips 104. The heat dissipation ribs 41 dissipate heat for the installed lamp panel 4, thereby reducing the possibility of overheating inside the lampshade 2.

[0044] Reference Figure 1 and Figure 7 When the temperature of the electric control box 1 is too high, the circulation pump 65 is started, and the coolant in the liquid storage tank 62 flows into the cooling tank 611 in the cooling plate 61 through the second connecting pipe 64, and the coolant after heat exchange flows back to the liquid storage tank 62 through the first connecting pipe 63. The cooling plate 61 cools the electric control box 1, further reducing the possibility of overheating of the electric control box 1.

[0045] The implementation principle of a dual-power ceiling lamp in the embodiment of the present application is as follows: under normal use, the driving power supply 16 is connected to the external power line to provide power for the lamp. When the external power is off or a fault occurs, the emergency controller 15 switches to the emergency power supply 14 to power the lamp, ensuring the normal use of the lamp under fault conditions. When one set of emergency power supplies 14 runs out or fails, the emergency controller 15 controls the switching of another set of emergency power supplies 14 to supply power, reliably ensuring the normal operation of the lighting equipment. In addition, without turning off the lamp, the two emergency power supplies 14 can be periodically charged and discharged through the emergency controller 15, which helps to extend the service life of the lamp.

[0046] The temperature sensor 54 detects the temperature in the electric control box 1. When the temperature exceeds the threshold, the cooling fan 51 blows air into the electric control box 1 to cool it down. The first heat sink 10 and the second heat sink 11 are provided to dissipate heat for the emergency power supply 14, the wiring terminal 12, the driving power supply 16 and the emergency controller 15. The heat dissipation ribs 41 dissipate heat for the lamp panel 4, thereby reducing the possibility of overheating inside the lampshade 2.
