Project Description

USheng electronics provides a set of teaching level green health sound and light scene solutions, on the one hand, effectively alleviate the visual and hearing fatigue of students in the teaching environment, reduce the incidence of myopia, and protect children and adolescents' audio-visual health. On the other hand, the use of wireless sound transmission system and even sound field, to protect the health of teachers' voice, make teaching more relaxed and pleasant, teachers and students interaction more natural and smooth, improve teaching quality and effect.

Friend sheng teaching level green healthy sound and light control system with independent intellectual property rights, leading technology, long service life (lighting lamps and lanterns, as long as 50000 hours) life, easy maintenance, energy conservation, environmental protection, power saving rate can reach more than 75%), etc, can effectively reduce the use and maintenance costs, one-time investment, can reduce the maintenance cost, loss, and upgrading for many years, maximize cost benefit.

Innovative lighting technology:

1. Blue light can be quantitatively filtered; 2. Anti-dazzle technology; 3. Stroboscopic strobos-free technology; 4. Far superior color rendering performance of similar products; 5. Accurate control of color temperature; 6. Professional lighting design.

 

Professional sound field design: balanced high fidelity sound field design.

1. Reasonable sound field power, optimal allocation and moderate loudness in the teaching environment of scientific design. Sound transmission is flat and sound field is balanced.

2. Professional audio processing makes the timbre pleasant, plump and clear, and the sound of natural dialogue makes students physically and mentally healthy.

3, pleasant sound to avoid hearing fatigue, teachers and students interactive teaching relaxed and harmonious.

4. Excellent and comfortable classroom sound environment enables students to clearly identify and understand the teacher's teaching content.

The VICO index of USheng health lighting was <1.8(mild fatigue), and the visual comfort was higher than ordinary LED lamp (VICO index 2.07-2.17) (fatigue was obvious but tolerable) and fluorescent lamp (VICO index 2.2-2.7).

Comparison of performance of yousheng teaching sound field and common amplification equipment:

Compare the item Unevenness of sound field
(the quieter the value, the more uniform the field)		 The advantages and disadvantages Send message transmission Teaching interaction between teachers and students
Small bee amplification equipment 6.8 Human voice distortion, easy to scream, attenuation serious Fatigue Convenient but local sound field, easy to damage hearing
The enclosure 3.5 Local loudness is too large, easy to whistle, attenuation is serious Fatigue Limited (wired transmission), easy to fatigue hearing
The teaching field 0.6 Sound field is balanced and clear, high fidelity, no noise, small attenuation Easy and convenient Free interaction (wireless transmission), hearing protection
