Description

Technical Field

[0001] The utility model relates to the technical field of elevator equipment, in particular to a lighting structure used for an elevator. Background Art

[0002] Elevators are becoming more and more popular, and the lighting system in elevators is a necessary component. Traditional lighting systems generally install downlights or modular light panels in the elevator car. This lighting structure is limited by the size of the lamp in terms of space utilization, which will affect the internal space of the car to a certain extent. Replacing the lighting configuration during the procurement, production, and installation process requires replacing the entire lamp, which has a high cost. Although some people have designed integrated, integrally luminous elevator car wall panels, the car wall panels use a direct lighting structure, that is, the light source is vertically irradiated against the light-transmitting window of the wall panel. This will inevitably increase the overall thickness of the car wall panel due to the need to provide installation space for the light source, which will also have an adverse effect on the internal space of the car and fail to fully utilize the free space in the car. At the same time, its structure is relatively complex and the cost is relatively high. Utility Model Content

[0003] The utility model aims at the shortcomings of the prior art and provides an integrated elevator lighting structure with simpler structure, more reasonable design, lower maintenance cost and higher utilization rate of the interior space of the elevator car.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: an integrated elevator lighting structure, which is installed in the elevator car, the car includes a car wall panel and a frame, and the frame is fixed on the four sides of the car wall panel; the lighting structure includes a light source, characterized in that: the car wall panel includes a light-emitting panel, a light diffusion layer, a light guide plate and a shading layer from the inside to the outside, the front of the light-emitting panel faces the interior of the car to form the inner surface of the car wall panel, the light diffusion layer is located on the back of the light-emitting panel, the light guide plate is attached to the outer side of the light diffusion thermal layer, and the shading layer is attached to the outer side of the light guide plate; the light source is installed in the frame and aligned with at least one side of the light guide plate.

[0005] Furthermore, the light emitting panel, the light diffusion layer, the light guide plate and the light shielding layer are bonded by glue to form a compartment wall plate of an integral component structure, and the four sides of the compartment wall plate are installed and fixed by the frame.

[0006] Further, a groove is provided on one side of the frame facing the side edge of the compartment wall plate, and the edge of the compartment wall plate and the light source are installed in the groove. The groove itself exists in the frame and is used to install the compartment wall plate.

[0007] Furthermore, positioning fixtures are provided near both ends of the groove, and the light source is installed and fixed by the positioning fixtures to achieve alignment with the side of the light guide plate, wherein the positioning fixtures are structural members in the frame itself for installing the compartment wall panel.

[0008] Preferably, the light source is a light belt or light bar of LED.

[0009] Preferably, the shading layer is a black, opaque plastic paper attached to the outer side of the light guide plate; and the light-emitting panel is an acrylic plate with a UV printed pattern.

[0010] Preferably, the light diffusion layer is a layer of white plastic paper with a frosted surface, and the light diffusion layer is attached to the back of the light emitting panel.

[0011] Alternatively, the light diffusion layer is a frosted surface formed on the back of the light emitting panel.

[0012] Preferably, the light source is arranged in the frame at a position aligned with one side, both sides, upper edge, lower edge or upper and lower edges of the car wall panel, and the distance between the light source and the side edge of the light emitting panel is not greater than 15 mm. In other words, the light source can be installed on the side of the car, or in the top ceiling structure or the bottom floor. Of course, it can be applied to the car of the car elevator, and can also be applied to the platform panel of the platform elevator.

[0013] The utility model installs the light source in the frame of the car and aligns it with the side of the car wall plate, so that the light source is injected into the light guide plate in a sideways and parallel manner, and then the light diffusion layer diffuses the light to emit uniform light on the light-emitting panel. In this way, there is no need to reserve installation space for lamps in the car, which can improve the utilization rate of the original space of the car, and at the same time, it is convenient to upgrade the lighting function by only replacing the light belt, reducing the maintenance and change costs.
