What is the difference between 12V xenon lamp and LED lamp, which is better

2020-07-07

LED lamps and 12V xenon lamps have been a hot topic in recent years. Many car owners are entangled in which is better, 12V xenon lamps and LED lamps. What are the differences between 12V xenon lamps and LED lamps? Let’s talk about 12V xenon lamps. Lights and LED lights!

12V xenon lamp

The 12V xenon lamp (HID) is a high-pressure gas discharge lamp. Its principle of light is to boost the 12V voltage to an ultra-high voltage of 23000V, excite the xenon gas filled in the quartz tube to make it glow, and then convert the voltage to about 85V. Stable and continuous supply of 12V xenon bulbs to emit light. The color of 12V xenon lights is closer to the white light at noon, and the lens is equipped with a better visual effect, which is sought after by many consumers. In addition, HID also avoids ordinary halogen lamps that are easily oxidized and emit The longer the bright time, the darker the light will be. The lighting distance is wide and long. In fact, in life, apart from having such a device in the car, the electric welding on the street is also based on this principle. The dazzling white light is xenon gas.

LED headlight

LED lights have a very popular name: light-emitting diodes. LED car lights refer to car lights that use LED (light emitting diode) as the light source. When it comes to LED headlights, everyone naturally thinks of Audi, which is "professional lighting". This car manufacturer, commonly known as "light factory", has been leading the trend in headlights, and Audi is also the manufacturer of the most models equipped with LED headlights. And LED has the characteristics of high brightness, rich color variety, super long life, high energy conversion rate, good safety, extremely fast starting speed, small size and power saving, etc. LEDs are widely used in the automotive field.

Comparison of 12V xenon lamp and LED lamp illumination effect

As to which of the two lamps is better, it still depends on the actual effect. From the comparison of the above figure, the 12V xenon lamp can see two light beams obviously produced by lens aggregation, and the brightness is relatively high, but there is a significant attenuation of brightness from the middle to the two sides.

The low beam of the LED headlights is immediately compared with the 12V xenon lamp. The brightness of the LED headlights is higher, the road surface is illuminated in a wider range, and there is no obvious phenomenon of light source decay, and the brightness is uniform. The LED headlights have an absolute advantage.

For some suburbs or highways, the effect of high beams directly affects driving safety. From the comparison chart above, it can be seen that the illumination width and distance of LED headlights are better than that of 12V xenon lamps, but in terms of penetration, LEDs are still inferior to 12V xenon lamps, because 12V xenon lamps have A lens can condense light, so the actual illumination effect is slightly better than LED headlights in some foggy days or road conditions.

Advantages and disadvantages of 12V xenon lamp

advantage

Relatively speaking, most of the advantages of 12V xenon lamps are compared with halogen lamps. Still life span is not as good as LED headlights.

1. Constant output, safe and reliable: When the car's power supply system and battery fail, the ballast will automatically shut down and stop working.

2. Longer life span, about 3000 hours

3. The power consumption is low. The general xenon headlights are only about 35W. Compared with halogen lamps, the vehicle performance is improved and energy is saved.

4. Good color temperature: 4300K-12000K, etc., 6000K is close to daylight, which is well received by users.

Disadvantage

1. The disadvantage of 12V xenon lamp is its high price.

2. There is a delay in turning on the light, generally it takes 3~4 seconds to reach the maximum brightness. At this time, I want to use the high beam to remind the incoming or preceding vehicle. The delay of these few seconds is not reliable, so many cars use xenon for the low beam, and the halogen lamp is still used for the high beam.

Advantages and disadvantages of LED headlights

advantage

1. Energy saving and environmental protection: The energy consumption of LED lamps is 1/20 of that of halogen lamps, which is naturally more energy efficient than 12V xenon lamps.

2. Low cost and long lifespan: The lifespan of LED lights from well-known manufacturers can reach 100,000 hours, which means that basically your car can't be driven and it is still on.

3. The brightness is high, and the horizontal width of illumination is wider than that of halogen headlights

4. Low-voltage safety: LED, the first element used in electronics, only needs a DC voltage of 12V to light up, and there is no need to worry about the voltage of more than 20,000 xenon.

5. Instant light up: No longer need the 12V xenon lamp "will turn on again", just use it anytime.

6. Small size, easy to design headlights into various shapes.

Disadvantages:

1. Poor heat dissipation will affect the life of LED headlights

2. The power saving of low-end LED lamps is still lower than that of energy-saving lamps (cold cathode tubes, CCFL).

3. The initial purchase cost is higher.
