Today, with the rapid development of automotive lighting technology, it has also led to the prosperity of the automotive lamp modification market, from the first halogen lamps, xenon lamps, to LED headlights, laser headlights, as well as lighting black technology, matrix headlights, geometry Multi-beam headlights, etc. However, there are still many models configured with halogen lamps. The lights are dim and dark, which affects the safety of driving at night. Therefore, many halogen lamp riders will choose to modify the lights. Then the question arises. Is the modification of the lights to improve the brightness. What about optical lenses? Let me tell you about the difference from the car headlight bulb to the double light lens.

First of all, we have to tell you that, as far as possible, the modification of the headlights should choose to add a lens. Car headlight bulbs include halogen bulbs, xenon bulbs, and LED bulbs. The lenses are divided into single-lens lenses and double-lens lenses. Generally, the current car lights are converted into double-lens lenses, including xenon lamp double-lens lenses, LED double-lens lenses, and laser headlights. Lens, etc., the lens plays a role of condensing light, while the dual-optic lens has the ability to switch between far and near beams. Let's start with the light bulb.

Earlier we said that the headlight bulbs include halogen bulbs, xenon bulbs, and LED headlights. Many Original bulbs come with halogen bulbs. The halogen bulbs have lower cost and yellowish light. They have good penetration in rainy and foggy days, but Daily lighting is still relatively poor.

There is also a xenon bulb, which consists of a bulb and a ballast, filled with an inert gas mixture including xenon, and a high-pressure gas discharge lamp without the filament of a halogen lamp (HID xenon lamp for short). The brightness of this type of bulb is much brighter than that of halogen lamps, but the naked xenon lamp is very dazzling, and the paving effect is not good. It is quite dazzling when it comes to the car, which affects the driving safety of the opposite vehicle. So this is also a reason why it is not recommended to install light bulbs, and the lights may not pass the annual review.

Let’s talk about LED headlights. LED headlights have no stabilizers. The integrated design of LED lamp beads and the cooling fan is more convenient to install than xenon lamps. LEDs are cold light sources. The lights are xenon lamps and halogens. The lights are mostly white compared to the lights, but the lights are still divergent, and the effect is not much improved. 

Let's talk about the lens below. Let's start with the xenon lamp lens. The only difference between the xenon lamp lens and the xenon lamp is an additional lens. Different lenses are equipped with different xenon bulbs and the effect of the stabilizer is also different. For example, the color temperature of the xenon bulb is 5500-6000K The lights are relatively white, close to the LED color temperature, but most of the xenon bulbs have a normal color temperature of 4300-5500K, and the light is warm white. It combines the use of rain and fog days, and the overall effect is better, but the xenon lamp has a start time, About 1-3 seconds, although the service life is longer than halogen lamps, there is still a gap compared with LED headlights.

The LED dual light lens is integrated with LED lamp beads, cooling fan, and lens, which is more convenient to install, and it is bright when there is no start-up time. Whether it is LED or xenon lamp, with the blessing of the lens, the low beam has an obvious tangent, Press the light on the road, the light is under the line of sight of the driver on the opposite side, and the double lens has the function of switching between far and near light.

Now, I believe that you all know the difference between the light bulb and the lens, so we recommend that you change the lamp and remember to add the lens. The friends who changed the lamp should also remember to use the light in a civilized manner and not abuse the high beam.
