Description
Technical field
The utility model relates to a kind of vehicle head lamp, relates in particular to by regulating colour temperature to reduce asthenopic vehicle head lamp.
Background technology
Head lamp is the illuminating lamp that plays the critical function that irradiates road ahead night, also referred to as headlamp.The brightness of head lamp must be enough to confirm at night the hindrance to traffic of the 100 meters of distances in the place ahead, but the performance reference of every country regulation is different.
Conventionally, the colour temperature that sunshine has that is called natural daylight is 5500K, but in fact each time period colour temperature is variant.
1) candle light when sun sets soon with 2200K is photochromic; 2) sun rises that after 10 minutes, to have the improved-type warm white fluorescent lamp of the color of 3000K photochromic; 3) sun rises that after 2 hours, to have white fluorescent lamp or the warm white fluorescent lamp of 4000K photochromic; 4) positive period of the day from 11 a.m. to 1 p.m the sun to have the cold white fluorescent lamp of 5800K photochromic.
But different from the time dependent sunshine of colour temperature, existing headlight irradiation is the light of colour temperature fixedly.
Fig. 1 is for showing the chart of each light source color temperature.
Light emitting diode (Light-Emitting Diode; LED) colour temperature of head lamp is higher than the colour temperature of existing head lamp light source.Conventionally the colour temperature of LED head lamp is 5500K, high-pressure discharge (High IntensityDischarge; HID) colour temperature of lamp is 4200～5000K, and the colour temperature of halogen (Halogen) lamp is 3100K.
Head lamp light source extensively adopts LED now, utilizes the light of the headlight irradiation blue and white (Blue-whitecolor) of LED, and the light of blue and white not only brightness is high, and significant visual effect is provided simultaneously.
But, if only staring at a kind of light of colour temperature, driver travels, can strengthen kopiopia.When this sees the display of same colour temperature for a long time just as us, to increase the weight of be principle of uniformity to kopiopia.
