Micro-structure light-guide for vehicle lamp development
  • Year:2012
  • Project:DOIT Program
  • Category:Head lamp lighting technology
  • Technique Features:

    With the unique feature of offering uniform luminous distribution, Micro-structured Light-guide for Vehicle Lamp is a type of light guide module to make the wanted pattern of lighting more recognizable. This advanced design complies fully with the requirement of the ECE-R87 (DRL). From the aspect of technology, by controlling the direction of lighting, the light-guide structure module can make the light from light source distributed uniformly. In order to offer the flexibility of lamp design ,by way of modularization, various light-guide modules can be arranged and assembled to form any intended luminous pattern.

  • Specification:

    1.Light source:LED;Wattage:0.1W~7W 2.Uniform of visual:uniformity is 80% or above 3.Center luminous intensity:above 400cd(for DRL) 4. Material:PMMA 5.Application:DRL、position lamp、rear fog lamp、reversing lamp、direction indicators、rear lamp、indoor reading lamp and traffic signs.

  • Applications:

    This design technique can integrate different light patterns and different sizes of micro-structured light-guide modules for all kinds of lamp designs, such as automotive lamp、traffic signs and indoor lamps. Accordingly, the design technique can greatly add artistic and visual value to lamp products.

  • Benefit:

    We can assist automotive lamp industry in establishing optical design capabilities and new product development so as to expand the light-guide lamp optical system market.
