Abstract

The utility model relates to an elevator car using quantum dot luminescent devices to illuminate, and belongs to the field of elevator car illumination. A first electroluminescence quantum dot luminescent device is arranged at the top end of an elevator car, and first 100-mm-wide soft electroluminescence quantum dot luminescent devices are pasted to the upper ends of three faces in the elevator car. Second electroluminescence quantum dot luminescent devices are adopted by the substrate portions of floor selection buttons, and the second electroluminescence quantum dot luminescent devices are adopted by the floor number parts of the floor selection buttons. The Elevator car using the quantum dot luminescent devices to illuminate has the advantages that the structure is novel, the quantum dot luminescent devices can completely meet the requirements of illumination and display of the elevator car, luminous efficiency and color saturation meet requirements, the effect of emitting light is stable and efficiency is high.

Description

Adopt the lift car of quantum dot light emitting device illumination

Technical field

The utility model belongs to the lift cage illumination field.

Background technology

Need illumination and display device in lift car.What use now is daylight lamp, LED, liquid crystal display.Because elevator is the S1 continuous duty, need continual illumination and demonstration, thereby not only need energy saving luminous efficient high, and more need long service life, working stability has high color saturation etc.The daylight lamp, LED and the liquid crystal display that use now still can not meet the demands fully, and especially light output and color saturation still owe not enough.

Along with the development of science and technology, people are pursuing new light source.Occur in the world first quantum dot solid-state white light source device in 2003, be practical the laying a good foundation of light source of quantum dot illumination.Quantum dot is organic material and High Efficiency Luminescence inorganic nanocrystal to be combined and the luminescent device with new structure that produces.Have wider spectrum with luminous comparing of organic material such as daylight lamp, LED, liquid crystal displays, the excitation wave of different wavelength can be excited by single optical frequency.Wavelength can extend to infrared band from visible light, stable luminescence, and efficient is high.Adopt quantum dot light emitting and display device cost can reduce half, colour gamut has improved 30 ﹪, power consumption decline 30 ﹪, and the life-span is doubled.

Summary of the invention

The utility model provides a kind of lift car that adopts quantum dot light emitting device illumination, with the problem of the daylight lamp, LED, liquid crystal display light output and the color saturation deficiency that solve present use.

The technical scheme that the utility model is taked is: electroluminescence quantum dot light emitting device one of car top installation, it is the flexible photoluminescence quantum dot light emitting device one of 100mm that interior three upper ends of car are pasted wide, floor selects the substrate of button partly to adopt electroluminescence quantum dot light emitting device two, and this floor selects the number of floor levels character segment on button to adopt photoluminescence quantum luminescent device two.

The utility model has the advantages that novel structure, the requirement that the quantum dot light emitting device can satisfy the elevator cage illumination fully and show, light output and color saturation meet the requirements, stable luminescence, efficient is high.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation that in the utility model car, floor shows;

Fig. 3 is the enlarged drawing that in Fig. 2, floor is selected button.

The specific embodiment

An electroluminescence quantum dot light emitting device 1 is installed on car 4 tops, and as key lighting and as the light source of photoluminescence, in car, three upper ends paste wide be the flexible photoluminescence quantum dot light emitting device 1 of 100mm, form the interior illumination of whole envelope; Floor selects the substrate of button 3 partly to adopt electroluminescence quantum dot light emitting device 2 301, choosing floor presses the button, electroluminescence quantum dot light emitting device 2 301 is just bright, this floor selects the number of floor levels character segment on button 3 to adopt photoluminescence quantum luminescent device 2 302, have light just bright, and two kinds of designs are the different spectrum that show.

Claims

1. lift car that adopts quantum dot light emitting device illumination, it is characterized in that: electroluminescence quantum dot light emitting device one of car top installation, it is the flexible photoluminescence quantum dot light emitting device one of 100mm that interior three upper ends of car are pasted wide, floor selects the substrate of button partly to adopt electroluminescence quantum dot light emitting device two, and this floor selects the number of floor levels character segment on button to adopt photoluminescence quantum luminescent device two.
