The headlamp assembly 100 according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, a head lamp assembly 100 according to an embodiment of the present invention includes: the lamp socket 110, the first lamp group 120, the second lamp group 130, a light switch (not shown), and a rainfall detector (not shown).
The first lamp set 120 is arranged on the lamp holder 110; the second lamp set 130 is arranged on the lamp holder 110 next to the first lamp set 120, and the color temperature of the second lamp set 130 is lower than that of the first lamp set 120; the light switch controls the first lamp set 120 and the second lamp set 130 to be turned on and off, and controls the first lamp set 120 and the second lamp set 130 to be turned on and off; rainfall detection spare is connected with light switch electricity, and rainfall detection spare judges the situation of rainfall in the environment through the liquid number of times or the liquid volume that collect in a certain period, and wherein, when light switch was started, when rainfall detection spare detected the rainfall and is less than or equal to first default, first banks 120 were lighted, second banks 130 were put out, when rainfall detection spare detected the rainfall and is greater than first default, second banks 130 were lighted.
It can be understood that when the vehicle is running in rainy and foggy weather, the rainfall in the surrounding environment can be detected by the rainfall detecting element, and whether the first lamp set 120 and the second lamp set 130 are lighted or not is determined according to the requirement. When the rainfall is detected to be less than or equal to the first preset value, the weather is normal weather or rain weather with small rain intensity, the interference on the sight of the driver is small, at the moment, the first lamp group 120 is turned on, the second lamp group 130 is turned off, and front road illumination is provided through the first lamp group 120; when the rainfall is detected to be greater than the first preset value, it is indicated that the surrounding rainfall is greater, the interference to the sight of the driver is greater, at the moment, the second lamp group 130 is turned on, and as the color temperature of the second lamp group 130 is lower than that of the first lamp group 120, the second lamp group 130 is turned on, so that the better road lighting effect is ensured, and the stronger light penetrating power is also achieved, and the second lamp group 130 with the weaker color temperature can remind the passing vehicle, so that the stronger glare effect can be avoided, and the driving safety is improved.
According to the headlamp assembly 100 of the embodiment of the invention, the rainfall detection piece is matched with the light switch to control the first lamp group 120 and the second lamp group 130 to be turned on, so that the light can be adjusted in a self-adaptive manner in an environment with poor sight in rainy days, the first lamp group 120 with a large color temperature is turned on in normal weather or under the condition of small rainfall so as to bring a good road surface illumination effect, and the second lamp group 130 with a small color temperature is turned on under the condition of large rainfall so as to bring a strong light penetrating power while ensuring the road surface illumination effect and effectively improve the safety of vehicle driving.
In some embodiments, the color temperature of the first lamp set 120 is between 5000K and 5500K, and the color is white with high brightness, but the wavelength of the light is short and the transmittance is poor, and the first lamp set 120 using the color temperature value can ensure a better lighting effect. The color temperature of the second lamp set 130 is 3000K to 3500K, the color is warm and white, the light wavelength is long, the second lamp set 130 adopting the numerical color temperature is low in color temperature, better optical conduction and penetration rate are achieved, the second lamp set 130 with the low color temperature is not easy to cause dazzling effect, light can effectively penetrate through a rain curtain, the driving safety of opposite vehicles is guaranteed, the opposite vehicles can find the coming vehicles in time, and therefore the safety is improved.
In some embodiments, when the rainfall detecting element detects that the rainfall is greater than the first preset value, both the first lamp set 120 and the second lamp set 130 are turned on. Because the colour temperature of first banks 120 is higher than the colour temperature of second banks 130, therefore, first banks 120 light is bright but the wavelength length, the penetrability is poor, the light of second banks 130 is warm on the contrary, but the wavelength length, the penetrability is good, first banks 120 and second banks 130 are all lighted, just also make second banks 130 can carry out the light efficiency compensation to first banks 120, weaken first banks 120 because of the influence that the penetrability lost caused in the rainwater, avoid the risk that road surface discernment degree reduces, can effectively promote the illuminating effect to the place ahead road when guaranteeing that head-light subassembly 100 has higher penetrability, it is narrow to avoid the view field that rainwater weather caused, the poor problem of visibility, and then improve the security of traveling.
