Elevator hall outer arrival indicator lamp device capable of automatically adapting to ambient brightness

Abstract

The invention discloses an elevator hall outer arrival indicator lamp device capable of automatically adapting to the ambient brightness, and belongs to the technical field of elevator hall outer arrival indicator lamps. The elevator hall outer arrival indicator lamp device capable of automatically adapting to the ambient brightness comprises an ambient photo sensor, a main control MCU and an elevator hall outer arrival indicator lamp which are installed on the outer wall of an elevator hall, the light ray intensity of the ambient can be obtained through the ambient photo sensor and convertedinto a digital signal, the main control MCU reads data of the sensor for processing, the data are compared with the preset threshold value and judged, a lighting control pulse with the corresponding duty ratio is output, accordingly, the brightness, matched with the ambient, of the elevator hall outer arrival indicator lamp is adjusted so that the situation that the arrival indicator lamp is too bright or too dim can be avoided, and meanwhile, the electricity consumption of the elevator hall outer arrival indicator lamp can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of an arrival indicator light outside an elevator hall, in particular to an arrival indicator light device outside an elevator hall that can adapt to the brightness of the environment. Background technique [0002] The arrival indicator light device outside the elevator hall is used to display the current location and status of the elevator. Whether it is night or day, the display light on the arrival indicator device outside the hall shows a certain brightness to remind people of the position and display of the button. In the working state of the button, some elevator hall arrival indicator devices have a dimming function, but they do not judge the brightness of the surrounding environment of the button. Humanized design is not convenient for people to use and meets people's requirements. In recent years, the arrival indicator light technology outside the elevator hall has been increasingly perfected. How t...

[0002] The arrival indicator light device outside the elevator hall is used to display the current location and status of the elevator. Whether it is night or day, the display light on the arrival indicator device outside the hall shows a certain brightness to remind people of the position and display of the button. In the working state of the button, some elevator hall arrival indicator devices have a dimming function, but they do not judge the brightness of the surrounding environment of the button. Humanized design is not convenient for people to use and meets people's requirements. In recent years, the arrival indicator light technology outside the elevator hall has been increasingly perfected. How to make elevator control more humane, more energy-saving and environmentally friendly under the premise of ensuring safety has become an elevator Control the pursuit of the goal, and at the same time put forward higher requirements for the design of the arrival indicator light

[0003] The basic function of the traditional arrival indicator light outside the elevator hall is to indicate the running direction of the elevator or indicate the pre-running direction of the elevator when it arrives at the station, but most of them use the indicator light with fixed brightness, which will be generated when the ambient brightness changes. Visual perception of being too dark or too bright
