Description

Technical Field

[0001] The utility model belongs to the technical field of LED lamps, and particularly relates to an LED lamp for elevator shaft lighting. Background Art

[0002] An elevator is a permanent transportation device that serves several specific floors in a building, with its car running on at least two rows of rigid rails that are perpendicular to the horizontal plane or have an inclination angle of less than 15° to the plumb line. There are also stepped types, with treads mounted on tracks and running continuously, commonly known as escalators or moving walkways, which are fixed lifting equipment that serve specified floors. A vertical elevator has a car that runs between at least two rows of rigid guide rails that are perpendicular or have an inclination angle of less than 15°. The size and structure of the car are convenient for passengers to enter and exit or load and unload goods. It is customary to use elevators as a general term for vertical transportation vehicles in buildings, regardless of their driving mode.

[0003] When maintaining and repairing elevators, lighting is required. LED lamps are very suitable due to their low power consumption and long service life. However, the existing LED lamps used for elevator shaft lighting are in working condition for a long time. Without accidents, the LED lamps will not stop working. After long-term lighting, a large amount of heat cannot be dissipated, which will cause the circuit board of the LED lamp to overheat and burn out, affecting the lighting efficiency.

[0004] Therefore, we proposed a new type of LED lamp for elevator shaft lighting. Utility Model Content

[0005] The utility model aims to provide an LED lamp for elevator shaft lighting, which solves the problem that the existing LED lamp for elevator shaft lighting causes a large amount of heat to be unable to be dissipated after long-term lighting during use, which may cause the circuit board of the LED lamp to be overheated and burn out, thereby affecting the lighting efficiency.

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0007] The utility model is an LED lamp for elevator shaft lighting, comprising a lampshade, the upper surface of the lampshade is fixedly connected to a connecting base, the lower surface of the connecting base is provided with a threaded socket, the upper surface of the connecting base is movably connected to a cooling circulation chamber, a limiting groove is provided at the center of the upper surface of the cooling circulation chamber, the number of the limiting grooves is five, the interior of the cooling circulation chamber is filled with coolant, the outer surface of the cooling circulation chamber is fixedly connected to a delivery pipe, the number of the delivery pipes is several, and the delivery pipes are evenly distributed on the outer surface of the cooling circulation chamber.

[0008] Furthermore, a light source circuit board is movably connected to the center of the upper part of the cooling circulation chamber, a buffer pad is movably connected to the lower surface of the light source circuit board, a lamp tube is fixedly connected to the lower surface of the light source circuit board, the number of the lamp tubes is five, and they are adapted to the limiting grooves, and the device can be fixed on the elevator shaft by connecting the threaded sockets on the outer surface of the base, and the limiting grooves are adapted to the lamp tubes so that the lamp tubes pass through the connecting base for limiting, and the coolant filled in the cooling circulation chamber can cool and dissipate the heat from the bottom of the light source circuit board when the light source circuit board works for a long time, and the buffer pad can protect the lamp tubes and the light source circuit board from vibration and shaking.

[0009] Furthermore, the upper surface of the cooling circulation chamber is fixedly connected to a heat dissipation chamber, and the upper surface of the light source circuit board is movably connected to heat dissipation fins.

[0010] Furthermore, there are several heat sink fins, which are evenly arranged inside the heat sink chamber. The delivery pipe passes through the heat sink fins and is compatible with the cooling circulation chamber. Through the setting of the heat sink fins, the heat above the light source circuit board is transferred to the heat sink fins. Through the setting of the delivery pipe, the coolant filled in the cooling circulation chamber circulates through the delivery pipe, and the heat in the heat sink fins is cooled in a second step.

[0011] Furthermore, an exhaust chamber is fixedly connected to the upper surface of the heat dissipation chamber, and a fan is fixedly connected inside the exhaust chamber.

[0012] Furthermore, a dust cover is movably connected to the upper surface of the exhaust chamber, and a dust net is fixedly connected to the inside of the dust cover. By arranging a fan inside the exhaust chamber, the heat in the heat dissipation chamber and the exhaust chamber is discharged upward to the external environment as the fan rotates. The dust net inside the dust cover prevents external dust from falling onto the fan and the heat dissipation fins, thereby affecting the heat dissipation efficiency.

[0013] The utility model has the following beneficial effects:

[0014] By arranging structures such as the lampshade, the connecting base, the threaded jack, the cooling circulation chamber, the limit groove, the delivery pipe, the light source circuit board, the buffer pad, the heat sink, the coolant, the fan, the dustproof net and the like, it is achieved that when the light source circuit board works for a long time, the coolant filled in the cooling circulation chamber effectively cools and dissipates the lower part of the light source circuit board, and the heat above the light source circuit board is transferred to the heat sink fins, and the coolant filled in the cooling circulation chamber circulates through the delivery pipe, and the heat in the heat sink fins is cooled in a second step, and the heat in the heat sink and the exhaust chamber is discharged upward to the external environment through the rotation of the fan. The dustproof net inside the dust cover isolates the external dust outside the device, so that the dust will not fall on the fan and the heat sink fins, affecting the heat dissipation efficiency, thereby solving the problem in the prior art that a large amount of heat cannot be dissipated after long-term use of lighting, which will cause the circuit board of the LED lamp to be overheated and burn out.

[0015] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
