但隨著LED晶片及LED封裝技術(shù)的快速發(fā)展，PC透鏡在紫外線照射、高溫環(huán)境下易黃化、造成的光衰已經(jīng)遠(yuǎn)遠(yuǎn)超過LED光源，抗腐蝕能力差，材料硬度低，表面易被風(fēng)沙刮傷，易靜電吸附空氣中灰塵，透鏡的出光率逐漸下降等缺陷，被更多專業(yè)制造商與終端使用者所注意。
而另一方面，玻璃透鏡的耐溫范圍寬、抗紫外線、抗腐蝕能力強(qiáng)、表面光潔度高等優(yōu)點，已被更多的行業(yè)專家、制造企業(yè)、終端使用者所認(rèn)可，并認(rèn)為未來戶外照明領(lǐng)域的產(chǎn)品將會越來越多的使用玻璃材質(zhì)的透鏡。
A New Technological Engine: "COB + Glass Lens" Paving the Way for the Future of LED Road Lighting
With the rapid development of LED chip and LED packaging technology, the limitations of PC lenses in road lighting have become increasingly apparent. Under ultraviolet radiation and high-temperature environments, PC lenses are prone to yellowing, causing light attenuation that far exceeds the degradation of LED light sources. Additionally, PC lenses have poor resistance to corrosion, low material hardness, susceptibility to scratches from windblown sand, and static attraction of airborne dust, all of which lead to a gradual decline in light output efficiency. These defects have drawn the attention of professional manufacturers and end-users alike.
On the other hand, glass lenses offer several advantages, including a wide temperature tolerance range, strong resistance to UV radiation and corrosion, and a high level of surface smoothness. These benefits have been increasingly recognized by industry experts, manufacturing enterprises, and end-users. Glass lenses are now seen as the material of choice for future products in the outdoor lighting sector, with their adoption expected to grow steadily in this field.
