(CRI-Shanghai, http://www.shcri.com/reportdetail.asp?id=450 )So far, auto lamps have developed from original candle lamps to commonly employed incandescent lamps. In recent years, new-sort HID (High Intensity Discharge) and LED lamps have also emerged. The LED luminous efficiency can reach 80%-90%. New-sort and intelligent LED lamps, which are called the fourth-generation auto light source, have turn into an outstanding member amongst global auto electronic goods and will be the new development orientation of auto lamps.
Compared with standard lamps, LED lamps have a lot longer service life. Its service life is 50,000 hours in theory and 20,000 hours in practice. Throughout the entire life span of vehicles, users generally do not need to replace the LED lamps. The begin time for LED lamps is only dozens of nanoseconds, a lot shorter than that of incandescent lamps. Therefore, drivers can have more reaction time. LED stop lamps and directional lamps can directly convert the electric energy into optical energy under low drive present, showing upstanding environmental protection and energy saving effects. Its drive current is only 1/4 of that of incandescent lamps. With modest size, LED can facilitate designers in changing the lamp shapes optionally to diversify the auto styles.
