Lift direction lamp display device

Abstract

The invention relates to a lift direction lamp display device. The lift direction lamp display device comprises a printed panel, a substrate, a circuit board and a base plate. An installation groove where the circuit board can be installed is formed in the upper surface of the base plate. The circuit board is installed in the installation groove. The circuit board is provided with a plurality of electrical elements and two display boards, wherein each display board is composed of a light-emitting diode and a sound making loudspeaker. The substrate is installed on the base plate and covers the circuit board. The base plate is provided with through holes enabling the display boards to be exposed. The substrate is further provided with a plurality of installation grooves arranged in an array. The upper surface of the substrate is covered with the printed panel. The lift direction lamp display device has the advantages that a groove is formed in the periphery of the bottom of the substrate installation groove, the display device is prevented from being shrunk and deformed in forming, the display device can be smoothly assembled, the assembly speed of the display device is not influenced, the display device can normally work, and the problem that the assembly efficiency is too low is solved.

Description

technical field [0001] The invention relates to a display device, in particular to an elevator direction light display device. Background technique [0002] At present, the elevator arrival lights seen on the market are generally installed beside or above the hall door, and it plays the role of displaying the elevator call. In order to facilitate passengers to know the floor position of the elevator car when it is going up or down, the floor number is displayed on the arrival light, which is convenient for passengers to wait for the elevator. Its installation is inconvenient, and the complex structure increases the cost, and the current elevator arrival indicator light also has a relatively single shape, lacks aesthetic feeling, and makes people tired, and in rainy days, the air is humid, and water droplets will form inside. Get rid of, affect normal work easily, therefore, just be badly in need of developing a kind of elevator direction light display device with anti-shr...

AI Technical Summary

Problems solved by technology

Its installation is inconvenient, and the complex structure increases the cost, and the current elevator arrival indicator light also has a relatively single shape, lacks aesthetic feeling, and makes people tired, and in rainy days, the air is humid, and water droplets will form inside. Get rid of, easily influence normal work, therefore, just urgently need to develop a kind of elevator direction light display device with anti-shrinkage and attractive in appearance, after searching, do not find the same or similar device with the present invention
