Abstract

The utility model discloses a self-illumination stair which comprises an illumination device, wherein the illumination device comprises a piezoelectric body and an illumination unit; the piezoelectric body is mounted on a stair step plate plane; a protective plate is arranged at the upper part of the piezoelectric body; and the piezoelectric body is connected with the illumination unit in series. In a process of walking up and down the stair, pressure generated by stepping on the piezoelectric body allows the piezoelectric body to generate electric charge, the electric charge can flow through a circuit formed by the piezoelectric body and the illumination unit, and therefore, the illumination unit illuminates. The illumination unit is used for illuminating stair steps and markers in a staircase. With the adoption of the self-illumination stair, the stair steps and the staircase markers in the staircase with insufficient light can be illuminated, the danger of step missing in the process of walking up and down the stair is avoided, and the electric energy is saved.

Description

A kind of self-luminous stair

Technical field

The utility model relates to the stair in building, particularly, is a kind of self-luminous stair with illumination, deixis.

Background technology

Have the upper stair downstairs for people in building, in the situation that night, insufficient light or power failure, people's stair activity may be stepped on because not seeing stair step empty contingency.In prior art, generally the light-emitting lamp of being controlled by audio-switch is installed in meeting in staircase, and these lamps need to make the building electric network source, and audio-switch also is very easy to damage, and sensitivity is inconsistent, the phenomenon that frequent appearance can not be opened light fixture or lamp Chang Liang.

Summary of the invention

The purpose of this utility model is to provide a kind of self-luminous stair, and described stair automatic luminous avoids stepping on empty danger downstairs.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of self-luminous stair comprise light-emitting device, and light-emitting device comprises piezoelectrics and luminescence unit, and piezoelectrics are contained on the stair step board plane, and piezoelectrics top arranges guard shield, piezoelectrics and luminescence unit series connection.

During stair activity, pin steps down in the pressure that produces on piezoelectrics makes it produce electric charge, and electric charge can be by the loop flow that consists of with luminescence unit, thereby makes luminescence unit luminous.Luminescence unit is used for illuminating stair step and staircase sign.

Self-luminous stair described in the utility model can illuminate at the staircase of insufficient light to mark time in the building, building and the staircase sign, have avoided upper and have stepped on empty danger downstairs the time, and saved electric energy.

The specific embodiment

Below in conjunction with accompanying drawing, the claimed technical scheme of the utility model is done and illustrated.

A kind of self-luminous stair described in the utility model as shown in Figure 1, 2, comprise light-emitting device; light-emitting device comprises piezoelectrics 1 and luminescence unit 2; piezoelectrics 1 are contained on tread 3 planes, and piezoelectrics 1 top arranges guard shield 4, piezoelectrics 1 and luminescence unit 2 series connection.

Piezoelectrics 1 are a kind of known materials, and when to its extruding or draw when stretching, its two ends can produce different electric charges.Luminescence unit 2 is comprised of light emitting diode, and these light emitting diodes can provide illumination.

As shown in Figure 1, described luminescence unit 2 is contained in tread 3 surfaces, luminescence unit 2 outer setting protective covers 5, and these luminescence units can make the people of stair activity see the accurate location of stair step clearly, avoid stepping on sky.

As shown in Figure 3, described luminescence unit 2 is contained on stair railing 6 or wall 7, is contained in the position that luminescence unit 2 on stair railing can illuminate railing, makes people easier to railing, thereby safer when stair activity.The luminescence unit 2 that is contained on wall is used for illuminating floor identification, emergency exit sign etc.
