X'inhuma l-ottimizzazzjonijiet tad-dawl edukattiv LED imfassla għad-dawl tal-klassi?
Students' eyesight has been a hot spot in the society in recent years, and problems such as blue light hazards, stroboscopic and glare of classroom lights have also attracted much attention. For example, does LED light source pose a safety hazard to the eyesight of children who are developing? To create a more comfortable and green teaching light environment, people have designed LED educational lights for educational lighting. So what are the optimizations of these LED educational lighting tailored for classroom lighting?
Tgħallimt mill-manifattur tal-lampa edukattiva LED li d-dawl edukattiv LED l-ewwel solviet l-akbar problema ta 'lampi LED ordinarji - dija, u installat apparat kontra-dija għas-sors tad-dawl LED. Hemm żewġ tipi ewlenin ta 'apparat bħal dan: pjanċa kontra d-dija-grilja u pjanċa kontra d-dija tal-mikropriżma. B'dan anti-leqqa, il-livell tad-dija (UGR) tad-dawl edukattiv LED jista 'jitnaqqas għal taħt il-15, filwaqt li l-livell tad-dija tal-lampi LED ordinarji huwa l-aktar akbar minn 20, u l-livell tad-dija stipulat minn diversi dokumenti f' l-industrija tal-edukazzjoni hija inqas minn 19. Dan ifisser li t-trattament tad-dija tad-dawl edukattiv LED huwa aħjar mill-istandard tal-industrija tal-edukazzjoni.
Id-dawl edukattiv LED ġie ottimizzat ukoll f'termini ta 'indiċi ta' għoti tal-kulur. L-indiċi tal-għoti tal-kulur, kif jimplika l-isem, huwa kejl tal-grad li fih il-kulur ta 'oġġett jiġi rrestawrat taħt ċertu dawl. Lampi LED ordinarji huma ġeneralment bejn 70-80, filwaqt li l-indiċi tal-għoti tal-kulur tad-dawl edukattiv LED huwa akbar minn 90, li jista 'verament jippreżenta l-kulur tal-oġġetti. Fil-preżent, id-dokument standard tal-industrija tal-edukazzjoni jipproponi li mhuwiex inqas minn 80. F'termini ta 'prestazzjoni tal-għoti tal-kulur, id-dawl edukattiv LED huwa aħjar mill-istandard tal-industrija.
Id-dawl edukattiv LED ġie ottimizzat ukoll għall-ipproċessar stroboskopiku. Għalkemm il-lampi LED ordinarji ma jistgħux jaraw it-teptip stroboskopiku bl-għajn, id-dejta turi li t-teptip tad-dawl (fond ta 'fluttwazzjoni) huwa akbar minn 20 fil-mija. Il-qari f'dan l-ambjent ħafif se jaċċellera l-għeja viżwali. Id-dawl edukattiv LED huwa ottimizzat, id-dawl stroboskopiku (fond ta 'fluttwazzjoni) huwa inqas minn 3.2 fil-mija, id-dawl huwa artab u komdu. Fil-preżent, id-dokument standard tal-industrija tal-edukazzjoni ma stipulax b'mod ċar il-valur ta 'stroboskopiku ottiku (fond ta' fluttwazzjoni).
The color temperature of the LED educational lighting source has also been upgraded. The color temperature of ordinary LED lamps is greater than 6500K, and the "Standards for Lighting and Lighting Hygiene in Primary and Secondary Schools" points out that the color temperature of educational lighting should be between 3300K-5500K. It happens that the color temperature of the LED educational lighting is stable at the value of 5000K!
LED educational lighting is also worthy of recognition in terms of blue light processing. Blue light is an important component of white light, which not only plays an important role in ensuring color rendering, but also regulates circadian rhythms. Usually the "blue light hazard" we hear refers to the 400-500 nm blue light band of the light source. If the radiant brightness is too high, the eyes may cause photochemical damage to the retina after looking directly at the light source for a long time. There is a unified rating specification GB/T 20145-2006/IEC62471 for blue light retinal hazard. The LED lamps for daily general lighting belong to Class 0 or Class 1, which belongs to the safety category, while the light of LED educational lighting has reached the exemption level.
