Profile structure of elevator car ceiling lamp and elevator car ceiling lamp

Abstract

The invention discloses a profile structure of an elevator car ceiling lamp and an elevator car ceiling lamp. The profile structure of the elevator car ceiling lamp mainly comprises a front border andthe like. The front border, a rear border, a left border and a right border are connected to form a rectangular frame. A middle cross beam is connected between the left border and the right border, and a middle vertical beam is connected between the front border and the rear border. The front border, the rear border, the left border and the right border are made from profiles A. Reinforcing holesare formed in the profiles A. Lamp fixing clamps are arranged above the reinforcing holes. Lamp installation faces are arranged on the outer sides of the lower portions of the reinforcing holes. A plurality of punching positioning grooves are formed in the two side and the upper side of each profile A. An assembling positioning groove is formed in the inner side of the bottom of each profile A. The middle cross beam and the middle vertical beam are made from profiles B. Lamp fixing clamps are arranged on the two sides of the upper end of each profile B, and an installation rod through grooveis connected to the lower portion of each profile B. The upper surfaces of the two sides of each installation rod through groove are lamp installation faces. Punching positioning grooves are formed inthe top ends of the profiles B. According to the profile structure of the elevator car ceiling lamp and the elevator car ceiling lamp, the profile structure is formed by assembling aluminum profiles,the ceiling height is decreased to 60 mm, an area source is adopted, and thus, light is evenly emitted from the ceiling; the dimming technique is adopted so that the strength, color temperature and hue of the elevator car ceiling lamp can be changed; and the lateral light-emitting technique is adopted, so that dark areas are reduced.

Description

technical field [0001] The invention relates to the field of elevator dome lights, in particular to an elevator car dome light profile structure and an elevator car dome light. Background technique [0002] The traditional elevator car ceiling is generally formed by cutting, punching, folding and welding processes with 1.2mm steel plates, and uses four to six installation connectors to connect with the elevator car. The length of the installation connectors is the same as the bending part The sum of the heights is usually above 170mm, and some are even higher. Since the bending parts of the ceiling frame are limited by the bending machine and tools, the size of the bending part in the bending direction has certain requirements. In order to improve the manufacturability, the traditional ceiling frame usually has a net height of more than 170mm; the traditional ceiling light frame The production process is complicated. First, the steel plate must be cut according to the size ...

AI Technical Summary

Problems solved by technology

It has the following disadvantages: the traditional ceiling lamp is installed on the side of the ceiling, because the height of the lamp itself and the linear distance from the light-emitting surface to the acrylic board are limited, if the light-emitting surface is too small, the dark area displayed on the acrylic surface can be seen, Customers feel uncomfortable; due to the use of line light sources, the light will be uneven after being emitted. In order to achieve a good effect, the height of the ceiling and the number of lamps can only be further increased, which is not economical
