Description

Technical Field

[0001] The present application relates to the technical field of teaching supplies, and in particular to a classroom sterilizing LED eye protection lamp. Background Art

[0002] Most of the chandeliers used in the classroom are LED eye protection lamps. There are two common types of eye protection lamps on the market, one is a DC eye protection lamp, and the other is a high-frequency lamp. The main principle of the DC eye protection lamp is to convert the AC current into a stable DC current through a DC voltage regulator, thereby emitting a soft and bright light like natural light, thereby achieving the purpose of eye protection; the principle of the high-frequency lamp is to use an electronic inverter to change the Hz of the current to speed up the flickering of the light so that the human eye cannot recognize the change, thereby achieving the effect of eye protection.

[0003] Because there are many students in the classroom, the number of germs and viruses carried by people will increase accordingly. For this reason, schools often require classrooms to be ventilated to avoid the aggregation and breeding of germs. However, there are many seats and benches in the classroom, and mops and buckets for cleaning are also placed within designated areas. These places are ventilation dead corners, which are easy to breed bacteria and retain viruses. Therefore, it is necessary to provide an LED eye protection lamp that can both illuminate and disinfect. Utility Model Content

[0004] The present application proposes a classroom sterilization LED eye protection lamp, which has the advantages of an ultraviolet lamp panel providing ultraviolet sterilization, ultraviolet rays converting oxygen in the classroom into ozone, ozone wrapping objects in the classroom to disinfect and sterilize, and a fan discharging the ozone accumulated in the classroom, so as to solve the problem that the existing classroom LED eye protection lamps only have lighting function.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical solutions: a classroom sterilization LED eye protection lamp, comprising a lamp stand, symmetrical side panels are arranged at both ends of the lamp stand, and two LED light boards for lighting and one ultraviolet light board for disinfection are arranged on the lamp stand; a control device, comprising a PLC control assembly for controlling the opening and closing of the LED light board and the ultraviolet light board, and wires, contacts I and contacts II that form a current loop; an exhaust device, comprising an air supply pipe for outputting air flow, a motor is arranged in the air supply pipe, and a fan is arranged at the output end of the motor for extracting gas in the classroom; an air flow duct, comprising a connecting pipe connected to the air supply pipe, an air gathering pipe for converging the air flow, and a uniformly distributed air hole pipe for increasing the air extraction area.

[0006] Preferably, two symmetrical contacts I and one contact II are provided on one of the side plates.

[0007] Preferably, two symmetrical steel cables are provided at the top of the lamp stand, and the top of the steel cables is connected to a fixing plate, and the fixing plate is fixed to the ceiling by expansion bolts, so as to suspend the lamp stand on the top of the classroom.

[0008] Preferably, an alarm is provided at the top of the lamp holder for reminding when the ultraviolet lamp panel is turned on.

[0009] Preferably, a component assembly I is provided at both ends of the LED lamp panel, the component assembly I is connected to the side panel by bolts, an electrical connection hole I is opened on the component assembly I, and the contact I is inserted into the electrical connection hole I.

[0010] Preferably, a component assembly II is provided at both ends of the ultraviolet lamp panel, the component assembly II is fixed to the side panel by bolts, an electrical connection hole II is opened on the component assembly II, and the contact II is inserted into the electrical connection hole II.

[0011] Preferably, a positioning frame is welded inside the gas transmission pipe, and the motor is fixed on the positioning frame.

[0012] Preferably, an isolation block is provided between the LED light board and the ultraviolet light board, the isolation block is provided with evenly distributed through holes that penetrate upward and downward, the gas collecting pipe is fixed on the top of the isolation block, and the pore pipe is inserted into the through holes.

[0013] This application has the following beneficial effects:

[0014] The present application provides a classroom sterilization LED eye protection lamp, which arranges an LED light board and an ultraviolet light board on a lamp rack. When the classroom needs lighting, the LED light board is turned on for normal lighting. When the classroom is empty and needs sterilization and disinfection, the LED light board is turned off and the ultraviolet light board is turned on to provide ultraviolet light into the classroom for sterilization and disinfection. The opening and closing of the light board is controlled by a PLC control assembly.

[0015] At the same time, when sterilization and disinfection are needed, close the doors and windows of the classroom to make the classroom temporarily in a relatively sealed state (the gap at the door will not have an impact). At this time, when ultraviolet rays are performing sterilization and disinfection, they will convert the oxygen in the air into ozone, allowing the ozone to diffuse in the classroom for secondary sterilization and disinfection.

[0016] At the same time, when the ultraviolet lamp is turned on for a specified time under the control of the PLC control assembly, it will be turned off. At this time, the motor starts to rotate the fan, forming a negative pressure in the air pipe. The gas in the classroom enters the air collecting pipe through the pore pipe under the pressure difference, and is input into the air pipe through the connecting pipe, and then discharged from the classroom through the air pipe, so that the ozone in the classroom can be quickly discharged, avoiding ozone accumulation and slow decomposition. When people return to the classroom, ozone still exists and causes injuries. BRIEF DESCRIPTION OF THE DRAWINGS
