Isn t the penetration of LED lights good in rainy and foggy days?

Suspended raindrops and particles in rainy and foggy weather scatter light, resulting in a decrease in illumination intensity, and the light penetration is only related to the color temperature, which is the k-value.

Matter. In general, the lower the color temperature, the better the penetration, and vice versa, the worse the penetration.

Halogen lamps. The color temperature is usually around 3500K, and the xenon lamp.

The color temperature is usually 4000K-5000K, and the color temperature of LED lights is usually 5500K-6000K. Nowadays, there are many different types and specifications of xenon lamps and LED lights, and the color temperature of each lamp is different, and the penetration of its light is not the same, so not all LED lights are not good in penetration.

If you need to upgrade your lights, we recommend OSRAM.

Brightener series LED upgraded lamp products and bifocal lens CBI LED modified LED headlight products, German quality century-old lamp brand, very good.

In rainy and foggy days, LEDs are not easy to copy, because the wavelength of the light of this lamp is a long wave, and the light cannot be refracted in the case of rain and fog in the air, and the penetration power decreases. The light of a yellow light (fog lamp) is a short wave, and the light can be refracted in foggy, rainy, and snowy weather. To put it simply, all car emergency lights in the world use yellow lights, because the penetration of yellow lights is the strongest in bad and extreme weather.

Hundred. The headlights are the headlights of the car, and the headlights are symmetrically installed on both sides of the front end of the vehicle when driving at night in order to identify the lighting fixtures of the front vision. LED is an electroluminescent device that uses a solid semiconductor chip as a light-emitting material, and directly emits light through the recombination of carriers to cause photon emission. LED headlights are lighting appliances made by using LED as a light source.

Rear fog lamps for vehicles are red signal lights installed at the rear of the vehicle in areas with low visibility, such as fog, rain or dust, to make it easier for road traffic participants to see other roads behind the vehicle, and have a greater luminous intensity than the tail lights.

Car bulbs with high penetration and brightness refer to bulbs with low color temperature and high lumenness.

The level of penetration depends on the color temperature, the higher the color temperature, the worse the penetration, and the lower the penetration, the stronger the penetration. As a reminder, we think that the penetration of halogen lamps is higher than that of xenon lamps and LED lights, in fact, it is not because the halogen lamps themselves are more penetrating than xenon lamps and LED lights, but because the color temperature of most xenon lamps and LED lamps is set higher by the manufacturer.

In fact, high color temperature and low color temperature have their own benefits, high color temperature light color whitish, close to daylight looks more comfortable, night paving effect is much better than yellow light, the disadvantage is that the tradition of rain and fog weather is poorer. Low color temperature is the opposite.

There is no direct relationship between high brightness and color temperature, but bulbs with high color temperature usually make people feel brighter, in fact, this is a visual misunderstanding, the level of brightness depends on the lumen value, the higher the lumen value, the higher the brightness.

Moreover, the current xenon lamps are generally equipped with bifocal lenses, and the bifocal lenses with good performance can also improve the brightness and penetration of the bulb.

Your question: Car bulbs with high penetration and brightness? First of all, when we talk about penetration, we are actually talking about color temperature.

The lower the color temperature, the better the penetration; The higher the color temperature, the worse the penetration. When it comes to penetration, it is generally said that fog lights, if you say headlights, refer to fog lights.

The color temperature of the original car halogen fog lamp is 2800K-3000K, that is, the yellow light, as long as it is used as a fog lamp, the color temperature of the car LED fog lamp must also be made of 2800K-3000K, yellow light, no manufacturer fog lamp will be 4300K or 6000K, 4300K is yellow and white light, 6000K is white light, if it is made like that, it will not become a fog lamp.

For fog lamps, it must be required to emit yellow light.

The lower the color temperature, the stronger the penetration, and the higher the color temperature, the weaker the penetration. You can pay attention to the fact that the vest of the traffic police has yellow stripes, indicating that the penetration of yellow light is very strong and very conspicuous.

Therefore, from the perspective of the color angle of color temperature, the penetration of automotive LED fog lamps and halogen fog lamps is the same, and they are both strong penetrating.

Then, let's talk about brightness. In terms of brightness, the brightness of the LED headlights is much brighter than the halogen bulb of the original car. Take the "5D car LED bulb C6F" that I asked to help modify here during this time, the power is 36W, and the energy consumption is only 60% of the original car halogen bulb, but the brightness is more than 4 times that of the original car halogen bulb.

Now people change the lights, and when they come to me and ask me to help install them, 95% of the riders are modified LED headlights.

So, back to your question, bulbs with high penetration and brightness, in general, are talking about the yellow light bulbs of LED headlights.

At present, the most penetrating headlights are LED headlights.

Nowadays, people generally use LED headlights. LED headlights are very popular among car owners because they are bright and energy-efficient. The power is 33W, but the brightness is 3-5 times that of the original car's halogen bulb.

Advantages of LED headlights:

High brightness, 4-6 times brighter than the original car halogen bulb; The temperature is very low, generally 50-70 degrees, because the temperature is low, the performance is very stable, there is almost no light decay, instant start-up, no delay. Moreover, the paving is very even, and it will not be like the halogen bulb or xenon lamp of the original car, one piece by piece, sitting in the cab, it is very comfortable to look at, and it is not easy to get tired of vision.

Xenon lamp, and then turn it up, and shoot the eyes of the oncoming car at night...

The most penetrating lights are the fog lights.

The penetration of the rain old Zen day LED light is okay. Compared with halogen light sources, the penetration of LED lights is weaker, because the wavelength of light is long-wave, and the penetration of LED lights will be reduced when driving in rainy and foggy days.

At present, there are four wide types of automotive headlights on the market, including LED headlights, halogen headlights, xenon headlights and laser headlights. Among them, halogen headlights are the most widely used in automobiles, because halogen headlights are the earliest one used in automobiles.

The color of the halogen lights is yellow, and the lighting effect is not very good at night, but there is no problem with normal driving. Compared with other types of headlights, the biggest advantage of halogen headlights is their strong penetration.

Xenon headlights are generally used in mid-to-high-end cars. Xenon headlights must be focused using lenses.

LED headlights are more popular in recent years. Many car manufacturers use LED headlights instead of halogen headlights. Compared with halogen headlights, LED headlights are energy-saving, environmentally friendly and durable.

The most important point is that the light intensity is relatively high. But in rainy weather, the LED headlights used in the car have no obvious advantages, and the lighting effect will be weakened.

The penetration of LED lights in rainy days is still OK, compared with the Luyuan halogen light source, the penetration ability of LED lights is weaker, because the light wavelength of LED lamps is long waves, and the penetration ability of LED lights will decrease when driving in rainy and foggy weather.

At present, there are four types of automobile headlights on the market, including LED headlights, halogen headlights, xenon headlights and laser headlights, among which halogen headlights are the most widely used in automobiles, because halogen headlights are the earliest used in automobiles.

The color of the halogen lamp is yellow, and the lighting effect at night is not very good, but there is no problem with normal driving, compared with other types of headlights, the biggest advantage of halogen headlights is that they have strong penetrating ability.

Xenon headlights are generally used in mid-to-high-end cars, and xenon headlights must use lenses, which can focus the light.

LED headlights are more popular in recent years, many car manufacturers have made the LED headlights with LED headlights instead of halogen headlights, compared with halogen headlights, LED headlights are more energy-saving, and environmentally friendly and durable, the most important point is that the light intensity is higher, but in case of rainy weather, the LED headlights used by the car have no obvious advantages in rubber stools, and the lighting effect will be weakened.
