摘要

This invention relates to collimator (100) for a light source (108), the collimator (100) comprising: a body (106), a cavity (110) formed on a bottom side (120) of the body (106) for housing the light source (108), the cavity (110) having an entrance surface (112, 114) arranged for receiving light generated by the light source (108), a total internal reflection, TIR, surface (124) provided at a side surface (104) of the body (106), an exit surface (102) provided at a top side (122) of the body (106) and arranged for emission of collimated light, wherein the entrance surface (112, 114) comprises surface roughness having a roughness value, such that improved light mixing of light from the light source (108) entering the collimator (100) is achieved.

8. Stone Matrix Asphalt (SMA) is a gap-graded mix that is gaining popularity worldwide. Generally, gap graded mixes are thought to be weak in fatigue resistance. In this study, cellulose fibers were pre-blended in PG64-22 binder with fiber proportions of 0.2%, 0.4%, 0.6%, 0.8% and 1.0% by weight of aggregates. The fiber-modified binder showed improved rheological properties and showed that the PG64-22 binder can be modified and raised to PG70-22 grade. The cellulose oil palm fiber (COPF) was found to improve the diameteral fatigue performance of SMA design mix. The fatigue life increased to a maximum at a fiber content of about 0.6%, whilst the tensile stress and stiffness also showed a similar trend in performance. The initial strains of the mix were lowest at a fiber content of 0.6%. [O] . Ratnasamy Muniandy, Bujang B.K. Huat 2006
