Light emitting principle
Rare (Ne-Ar mixed gas) appropriate amount mercury vapor sealed cold cathode fluorescent lamp. When high electric field applied lamp, electrons accelerated cause elastic collision with rare gas, with mercury atoms adjusting speed, then radiation ultraviolet (primarily 253.7 emitted. Phosphor absorbs ultraviolet excited convert into visible light energy conversion.

This particularly evident temperature start-up. Contact Engineering Dept effective countermeasures.
Ambient Temperature (Lamp Surface Temp.) Characteristics
mercury vapor pressure largely depended ambient temperature (lamp surface temperature), fluorescent lamp ambient temperature (lamp surface temperature) characteristics. Ambient temperature (surface temperature) low: Emission efficiency becomes because excitation caused shortage mercury vapor pressure. Ambient temperature (surface temperature) high: Emission efficiency becomes because radiated ultraviolet reabsorbed outer mercury. general, thinner lamp, makes re-absorption ratio lower, therefore optimal temperature becomes higher. heat dissipation state system bad, lamp surface temperature will become higher than optimal value, luminance will lowered. Cautions required, when driving with large current, when using many lamps together. Although luminance increased lowering pressure, even when heat dissipation state good, will result shorter life. heat dissipation state system good, lamp wall temperature will become lower than optimal value, luminance will fall. Cautions especially required, when lamp thin drive current low. Regarding luminance fall under good heat dissipation state, although increase luminance achieved increasing pressure, will result increase lamp electric power.

Distribution lamp surface temperature mercury
With Sanken CCFLs except those sets, nearly equal volume mercury intentionally placed both ends lamp near electrode (outside effective emission area). This increase lamp life (low temperature life particular). lighting, temperature inside lamp rises, mercury vaporized high pressure diffused. lights-out, evaporated mercury returns liquid mercury adhered inside lamp. Because this, mercury near electrode gradually (taking long time) moves effective lighting area, volume mercury thus moved significant cause decrease back-light luminance. When lamp surface temperature distribution inappropriate, however, mercury gathered coldest area, will shorten life lamp. details, Section 4-2, "Defects Caused Mercury Migration Gradient Lamp Surface Temperature," page very difficult judge whether lamp wall temperature distribution unit state proper measuring lamp wall temperature directly. Instead, judged whether lamp wall temperature distribution proper checking distribution mercury. Please contact Engineering Dept. about detailed check method.
