Yuannengji Tugann teocht dath soilse sráide faoi stiúir i radhairc soilsithe éagsúla mothúcháin éagsúla do dhaoine. I radhairc íseal-éadrom, Déanann solas teocht íseal-dath go mbraitheann daoine sásta agus compordach; déanann solas teocht ard-dath go mbraitheann daoine gruama, dim, agus fuar; i radhairc ard-éadrom, Déanann solas teocht íseal-dath daoine a bhraitheann stuffy; déanann solas teocht ard-dath go mbraitheann daoine compordach agus sásta.
Glacann an modh nua um choigeartú teochta dath stiúir an réiteach soláthair cumhachta tiomáint dimming PWM, cuireann sé ciorcad coigeartaithe teochta dath le ciorcad cúl-deireadh an tsoláthair chumhachta, agus glacann an ciorcad coigeartaithe teocht dath PWM lasc dimming a choigeartú an cóimheas idir an t-am seolta an t-eagar stiúir fuar bán éadrom agus an t-eagar LED solas bán te chun coigeartú teocht dath a bhaint amach.
LED street lights with a color temperature of about 5000K emit white light, and those with a color temperature of about 3000K emit yellow light or warm white light. Yellow light or warm white light of around 3000K is more suitable for road lighting, while Soilse sráide faoi stiúir with a color temperature of around 5000K are not suitable for road lighting. Because the color temperature of 5000K will make people feel very cold and dazzling visually, it will cause excessive visual fatigue, and under this color temperature condition, people’s long-distance observation ability will also decrease. During the packaging process, by applying phosphors with different excitation wavelengths and adjusting the amount or proportion of phosphors, LED white light sources with different color temperatures can be obtained. Color temperature is a scale representing the color of the light source. When the radiation of an absolute black body is exactly the same as the radiation of the light source in the visible light region, the temperature of the black body is the color temperature of the light source.
Different light sources emit different color temperatures. The characteristic of low color temperature light sources is that the red radiation in the energy distribution is relatively more, usually called “warm light”; when the color temperature increases, the proportion of blue radiation in the energy distribution increases, usually called “cold light”.
Medium color temperature, color temperature is between 3000–6000K. People do not have a particularly obvious visual psychological effect under this color tone, and feel refreshed; mar sin a thugtar air “neutral” teocht dath. Nuair a bheidh sé soilsithe ag foinse solais teocht mheán dath, mothaíonn gorm fionnuar.
Teocht dath ard: Nuair a sháraíonn an teocht dath 6000K, tá an dath éadrom gorm, mothú fionnuar a thabhairt do dhaoine. Nuair a bheidh sé soilsithe ag foinse solais teocht ard dath, mothaíonn rudaí fuar. Teocht dath agus gile Faoi ionradaíocht foinse solais teocht ard dath, mura bhfuil an gile ard, tabharfaidh sé atmaisféar gruama do dhaoine; faoi ionradaíocht foinse solais teocht íseal dath, má tá an gile ró-ard, tabharfaidh sé mothú stuffy do dhaoine.
