Because there are street lights in the city at night, the original car headlights are halogen candle lights with lenses and the light source is relatively dim. I have never felt that it has any impact. When there are street lights, I often don’t feel that the lights are turned on. As for lights, when everyone is changing to xenon headlights and LED headlights, they continue to use halogen lights. Although the bulbs will break from time to time, it is quite annoying. Fortunately, replacement is easy and cheap, and it is enough. The principle has always been used in this way. Last month, I walked a lot at night when I returned to my hometown, and there were no street lights. I suffered from the disadvantages of lighting and not installing a driving recorder. So this time I came back and made up my mind to install a driving recorder and change the LED headlights. I also figured it was time to change the light bulbs. when. In addition, the price of LED is now much more cost-effective than in previous years, and the technology is relatively mature, so it is time to replace the LED headlights.
The effect of halogen lamps at night is that the light is yellowish and the illumination is not very far. The effect difference between the low beam and high beam lights is not obvious after switching. To replace the headlight source, you must first understand the common types of car headlights. There are three common types of car headlights: (1) halogen headlights (2) xenon headlights (3) LED headlights. (4) Laser headlights are currently only equipped for use on a very small number of high-end cars. Many manufacturers have restrictions on turning on laser headlights. If no lights are detected in the oncoming lane, they can be turned on passively. In most cases, LED lights are still used. After asking experienced drivers and browsing forums for two days, replacing LED headlights is the best solution that meets the needs.
(1) Halogen lamp
Halogen headlights are one of the most common car headlights currently used in cars. Halogen headlights are modified from incandescent lamps. The principle is to add halogen gas into the incandescent bulb. Adding halogen gas can make the halogen bulb more durable than incandescent bulbs. durable. The advantages of halogen lamps: simple structure, low manufacturing cost, low price, and relatively mature technology. The color is yellowish and has a strong penetrating effect in extreme weather such as rain, snow, fog, etc., so halogen lamps are mostly used in fog lamps.
The disadvantages are also obvious: the irradiation distance is not far, the heat is high during use, the efficiency is low and the power consumption is high! Halogen lamps emit light through tungsten filaments. The filaments are easy to sublimate and fall off, and have a short service life. Especially when driving with others, I feel like my own car light source is like a candle.
(2) Xenon headlights
Xenon headlights are a type of gas discharge lamp. In the past few years, there has been a craze for replacing xenon headlights. Compared with halogen lamps of the same wattage, xenon lamps are more than three times brighter, have a longer service life, and consume less energy. Said to be more energy efficient than halogen lamps. The disadvantages are also obvious. Xenon headlights need to be used with lenses, otherwise the light will easily diverge and look very bright, and the visibility in the car will be average! Xenon headlights require a process of supercharging. Before supercharging, the brightness is very low, and modification is relatively troublesome at least! Xenon lamps require a cold start warm-up process of about 30 seconds.
(3) LED headlights
LED lights are light-emitting diodes, which were often used in tail lights, turn signals, and daytime running lights. Due to their relatively good advantages, more and more models use LED light sources as car headlights. Its optical structure Similar to xenon lamps, LED light can be condensed into parallel light through reflectors and lenses. The advantages of LED headlights are obvious. The energy consumption is only one-twentieth of traditional halogen lamps. It has a long life and good durability. The components are small in size, compact and easy to arrange and design. They have fast response speed and low brightness attenuation. They can be driven by low-voltage DC. They have small loads and weak interference. They have low requirements for the use environment. The LED units can be driven by low-voltage DC and have small loads. Unlike xenon lamps, which require a booster device. There are also disadvantages. In rainy and foggy days, the penetration is poor and there are heat dissipation problems. Therefore, common LED headlight models are equipped with fan heat dissipation structures.
After returning, Moudong searched for the price of LED headlights. It was within the budget and much lower than the imagined modification budget. I checked the car light type by browsing the forum, and checked the model with customer service just to be on the safe side. The principle of purchasing consumer products is to give priority to brands within the budget, especially brands that have purchased related products, and are more familiar with the endorsement of this company. As a practitioner of supply chain development, we are more willing to trust old brand manufacturers. The reason why Becoming a brand requires time to accumulate, in addition to better product competitiveness, after-sales service and industry reputation. During this period, I asked the store's customer service about issues such as installation and model interfaces. The professionalism was satisfactory. The professionalism of a store's customer service also greatly affects users' orders. I selected several LED headlights from Philips and added them to the shopping cart. Model matching was queried before. In addition, the original car lights are from Philips. I usually buy a lot of products from this brand, and the overall experience is good, so I still trust Philips products.
When I was shopping on JD.com on the 16th, when I opened the APP shopping cart, I found that the Philips LED car lights I was paying attention to were discounted by 100 yuan. I took advantage of the discount promotion and made money if I could save, so I placed an order directly. Jingdong's self-operated service is very fast. It arrived the next morning. I chose to go to the store for installation. During the installation, I asked the store's customer service some installation and model interface issues. It can be said that the professionalism of the store's customer service is very satisfactory. The customer service of a store. Professionalism also greatly affects users’ order placement.
I received the goods and wanted to share them. I took two photos and threw them away, because I have been following my friends to buy stuff these days. I am busy signing for a lot of express delivery every day, so I put aside the content of posting things and pictures, and wait until I go to work on Monday to install it. I am more worried about the heating problem of LED lights. After receiving the goods, I looked at the actual product. It has an aluminum structure for heat dissipation and comes with an active fan.
Regarding the color temperature of the headlights, the reason why halogen lights are yellowish is because the color temperature is low, lower than 4500K. Some modified xenon headlights look bluish and cold, and the color temperature may be above 10,000K. When the color temperature is 6000K, the color is white light, close to natural light. Most people see best in this environment and are less prone to visual fatigue. The color temperature of LED lights is generally in the range of 5000-7000, so this is the main reason for choosing LED lights.
Installation process:
The installation is done at the selected store, and the installation fee is 40 yuan, with no additional fees. Because it is an upgrade of the same model of LED lamp beads, the installation match is perfect. It saves time and effort than disassembling and installing it yourself. When placing the order, the order is placed on the company computer, and the matching installation store is near the unit. I hurriedly installed it at the store I went to during lunch on Monday. The installer said it would take a while to install it. I went out for a meal and had it installed when I came back. No photos were taken either.
The last two pictures are the high and low beam effects after installation. The effect of LED high and low beam cars is shown in the picture below. The effect exceeds expectations and the brightness is comparable to the effect of xenon lamps. I was previously worried that the 6500K color temperature would have poor penetration in rainy days. Xenon lamps have the problem of poor penetration in high color temperatures. After testing on the road in rainy days, the Penetration is absolutely fine.
At the beginning, I also looked at Philips’ LED car lights for about 1,000 CNY, with a color temperature of 5800K and an FOM increase of 200% LED. The effect after installation should be perfect, but it is a bit expensive for my car. Finally, I bought the third-generation Xingyaoguang 3000 with a color temperature of 6500K. Before purchasing, I was worried that the 6500K color temperature was too bright and the color temperature would have poor penetration in rainy days. After testing, the penetration was no problem at all.
Final summary:
When modifying LED headlights and buying lamp bead accessories, you can buy them during e-commerce event days. It is a very good choice to upgrade to the same model of lamp beads. The price is friendly and the light source performance is strong. In addition, everyone is driving at night when there are vehicles. When on the road, try to wear light-colored or reflective clothing. It is difficult to see if you are wearing dark clothes, and the distance is very close when you see it. If you react slowly, you will not be able to stop the car, which is very dangerous. Being responsible for yourself is also responsible for others.
