Which is brighter for car lights?

Automobile headlights are divided into LED lights, xenon lights and halogen lights. How to choose these three kinds of headlights? How can we distinguish the quality of LED lights? Subjectively speaking, xenon headlights and LED headlights can't be judged. We should compare the actual physical work rate. The brightness of a candle light in a cone-shaped angle within one meter is 1 lumen, The brightness of ordinary 40W incandescent lamp is 400 lumens, while the power of automobile xenon lamp is 35W, and the brightness of automobile xenon lamp is 3200-3600 lumens, while the brightness calculation of LED headlamp is more complicated. LED bulb is composed of a single LED lamp bead. Generally, the brightness of 1wled lamp bead is about 80-100 lumens, and some LED lamp beads in theory can reach 11 0-130 lumens. But ordinary goods can't reach such a high brightness. 100 lumens is the upper limit. LED headlights are generally equipped with ballast and separate voltage stabilizing device, and the power is not low, which causes a great burden on the circuit system of the whole vehicle. In fact, the brightness of LED headlights can be lower than that of xenon headlights, but it may be higher.

Why do LED lights look brighter

So why do LED headlights look brighter? In fact, the life span of LEDs with good heat dissipation design is very long, but the quality of refitted bulbs is uneven now. If you want to replace them, you need to polish your eyes. If you want to refit xenon headlights, you need to change the circuit of the original car, and match them with ballast and lens to standardize the light type. The life span of LED headlights is 15 times that of xenon headlights, According to personal experience, xenon headlights are still recommended. Of course, in the future, LED is the mainstream. The headlight uses LED beads. Compared with ordinary halogen bulbs, the brightness of LED beads will increase about 2-4 times under the same power. Many matrix LED lamp sets have very mature heat dissipation schemes, and their practical life will be greatly improved. In addition to lens and xenon bulb, ballast is the core of driving bulb, its quality determines the life of your headlight. Put the car head on the wall, about 5m away, and then look at the tangent line of the light. If there is tangent line and the light is uniform, it means that the lens has good concentration, but the brightness of halogen bulb is low, so replacing xenon bulb or LED bulb can solve the brightness problem of headlight The brightness can be increased about 2 times, which can meet the daily use.

The usage of automobile headlight and vehicle language

However, there are some hidden dangers in refitting the lights. After that, if you are afraid that your car will not be guaranteed. Xenon lights and LEDs have their own advantages and disadvantages. Now xenon technology is mature and reliable, with high cost performance. If xenon headlights are on the opposite side of the car, they will always be on the high beam. With the distance between the car owner and the vehicle, the LED headlights will be able to automatically identify the working conditions of the car and realize the automatic opening and closing of the high beam, In terms of automobile headlights, you can flash the headlights to remind the vehicle in front of you to get out of the lane. The headlights will flash twice. When you meet, you can remind the other party to switch the high beam lights to the low beam lights. If the headlights flash three times, you can remind the driver in front of you that his vehicle is in trouble and you need to stop for inspection.

Advantages of LED headlights

The biggest advantage of LED lights is energy saving. The eyes of the car are the headlights. In addition to the shape, there are many choices for the bulbs, such as halogen lights, LED lights and xenon lights. The actual observation brightness and exposure distance of the human eye are still relatively large. The xenon lights have stronger penetration and are not scattered. The LED penetration is relatively poor, Especially in rainy days, it's a bit like it's not opened. The LED astigmatism cover is used for the astigmatism cap of the LED lamp, which can suppress the glare of the bright LED on the pedal. The bulb temperature of xenon lamp is very high. If it's genuine, it won't break down. The maintenance cost is low. Xenon lamp is stronger than led, but its life is not as long as LED. The most damaged one is xenon lamp. However, for people who often drive through mountains, it's foggy and rainy in some places, so halogen lamp is the best one to use, with strong penetration.
