Claims (8)

  1. 一種照明模組，包括：一導光棒，包括：一第一端面；一第二端面，相對該第一端面而設；及一柱面，設置於該第一端面及該第二端面之間，該柱面包括一出光面及一反射面；一光源，鄰設於該導光棒之該第一端面外側；以及一反射套筒，套設於該導光棒之該第二端面外側，該反射套筒具有一反射腔，該反射腔自其外周向內漸縮而形成一頂角，其中，該光源之一部分入射光經由該反射腔反射至該反射面後再反射至該出光面以出光或經由該反射腔直接反射至該出光面以出光。
  2. 如申請專利範圍第1項所述之照明模組，其中該反射腔包括一第一反射區及一第二反射區。
  3. 如申請專利範圍第1項所述之照明模組，其中該頂角係偏離該導光棒之該第二端面的中心。
  4. 如申請專利範圍第1項所述之照明模組，其中該頂角係對應至該導光棒之該第二端面的中心。
  5. 如申請專利範圍第1項所述之照明模組，更包括一燈帽，用以套設於該反射套筒之一尾部。
  6. 如申請專利範圍第1項所述之照明模組，其中該第二端面係一平面狀之端面。
  7. 如申請專利範圍第1項所述之照明模組，其中該部分入射光係介於+2度至-2度之入射角度的入射光。
  8. 如申請專利範圍第1項所述之照明模組，其中該頂角係介於100度至170度之間。
