Beschreibung
Zusammenfassung:	The optical lens subassembly of this invention includes the optical lens, the projective tube, the coolant and the cooling cavity with a Teflon coat whose basis is polyvinyl fourfold fluoride.On the side of the cooling cavity there equipped a cooling plate. Because the cooling cavity adopts a Teflon coat, according to the physical characteristics of Teflon material, the light losing rate of the subassembly in the process of light transmission and reflection has decreased, which make the brightness upgrade, the screen more vivid so as to improve the screen quality.
