The controllable LED staircase lighting device described in the utility model is composed of LED light-emitting diodes, buttons, single-chip microcomputer and power supply. Described LED light-emitting diode is installed in the position of vertical ground 45 ° angle inside stair handrail lower side; Two buttons are installed beside the handrail of every floor stairs, one up and one down; Described button controls LED light-emitting diode by single-chip microcomputer, so The single-chip microcomputer described above adopts the STC89C52 chip. Because the utility model adopts multiple groups of LED connections, it adopts a more humanized lighting design "lights move with people", thereby obtaining better corridor lighting effects, saying goodbye to the disadvantages of traditional light sources that one light controls a staircase, even if one LED Damage will also not affect the overall lighting effect of the stairs. LED is small in size, easy to install and maintain. It is very convenient and the beautiful design of staircase lighting is more appreciative.

Description

Controllable LED staircase lighting

technical field

The controllable LED staircase lighting device described in the utility model relates to an LED light-emitting diode lighting device.

Background technique

Most of the currently used corridor lights have poor lighting effects, low lifespan, high maintenance costs, and serious aging phenomena, especially the sensitivity of sensor devices has decreased. Aiming at the above-mentioned problems in the prior art, it is very necessary to study and design a new type of controllable LED staircase lighting device, so as to overcome the problems in the prior art.

Contents of the invention

In view of the problems existing in the above-mentioned prior art, the purpose of this utility model is to study and design a new type of controllable LED staircase lighting device, so as to solve the problem of poor lighting effect, low service life, high power consumption, high maintenance cost, and easy Aging and other serious problems. The controllable LED staircase lighting device described in the utility model is composed of LED light-emitting diodes, buttons, single-chip microcomputer and power supply. The LED light-emitting diodes are installed inside the stair handrail at a 45° angle vertical to the ground. Two buttons are installed next to the handrail of each floor of stairs, one up and one down. The buttons control the LED light-emitting diodes through a single-chip microcomputer, and the single-chip microcomputer adopts an 8051 single-chip microcomputer STC89C52 chip.

The connection of single-chip microcomputer described in the utility model and button and LED light-emitting diode is as follows, P00---P07, P20-P27, P12 and P13 of single-chip microcomputer are respectively connected with LED light-emitting diode on the stair handrail, P10, P11, P14, P15 of single-chip microcomputer Connect the buttons S1, S2, S3, and S4 on the handrail of the stairs respectively.

The controllable LED staircase lighting device described in the utility model adopts LEDs embedded in the interior of the staircase handrail, and is installed at 45° vertically to the ground (the position of the LEDs can be changed according to the shape of the specific corridor).

Take the second-floor staircase as an example: When people step into the corridor, press the upstairs button on the first floor, the LED lights will light up one by one, and illuminate the stairs in sequence until the second floor; when reaching the second floor, there will be one up and one down. For the button of the floor, if you press the button for going upstairs, the LED lights will light up one by one until the third floor; if you press the button for going downstairs, the LED lights will light up one by one from the second floor until the first floor; when going downstairs from the third floor, Press down the downstairs button, the LED lights will light up one by one until the second floor.

The controllable LED staircase lighting device described in the utility model can be turned on and off sequentially according to the difference of the number of people and the sequence of going up and down stairs. There is no program stagnation problem of going up and down stairs at the same time. In case of an emergency, you can double-click the staircase button to achieve full lighting effect (at this time, the corridor LED is fully bright).

The controllable LED staircase lighting device described in the utility model adopts multiple groups of LEDs to connect, and bids farewell to the drawbacks of traditional light sources that one lamp controls a staircase. Even if one LED is damaged, it will not affect the overall light effect of the staircase. LED is small in size, easy to install and maintain. It is very convenient and the beautiful design of staircase lighting is more appreciative.

The utility model adopts a more humanized lighting design "lights move with people", thereby obtaining better corridor lighting effects and reducing unnecessary energy waste. The maximum light efficiency utilization is realized in the minimum space, which greatly reduces unnecessary energy loss.
