Car Head/Tail Lamp Characterization System:

We provide system solution to characterize the optical flux (lumen) and color temperature of car head/tail Lamp.

1. Current Meter 2. Device under Test 3. Integrating Sphere
4. Monochromator 5. Personal                  Computer 6. Power Supply
7. Silicon Detector 8. V(λ) Detector

9. 1/2 Axis Stepping Motor
10. Stepping Motor Controller 11. Light Box 12. Iris

1. Head/Tail Lamp optical flux (Lumen) characterization schematic:

After the lamp is stable, the emitted optical flux is collected by the integrating sphere then detected and read by the V(λ) detector and current meter, respectively.

2. Head/Tail lamp spectral distribution, color temperature analysis schematic:

Light collected by integrating sphere is then guided into the monochromator via a glass fiber. The spectral components are separated by monochromator and detected by the silicon detector. The spectral amplitude is read by current meter and then stored and processed by personal computer to show the spectral distribution,  and color temperature.
