[YesAuto headlight test] To talk about recent popular new cars, BYD Han must be one of them. I believe you have seen a lot of test drive content for this car. From the outside to the inside, Han has actually proved his “big” strength. But in my opinion, especially in recent years, the problems of Chinese brand models are not in appearance, interior, space and power, but often in some very detailed places. So today, our focus is on such a more detailed configuration-headlights, we want to test the BYD Han headlight assembly in all directions.

Overview of headlight assembly

Does it sound a bit confusing? Simply put, three LED light sources on the left and right sides of BYD Han are arranged in the light group. When the low beam is used, all three lights are on (the low beam is the main light source), and two when the high beam is turned on. The two light sources will be switched to high beams (one is a lens structure, the other is a reflective bowl structure) to take on the main lighting task. The arrangement order of the light sets of EV and DM models is slightly different.

We guess that the reason for such a mix and match arrangement is to use the different characteristics of the reflective bowl and lens structure to make up for their relative disadvantages. Of course, the actual lighting and glare performance cannot be guessed, depending on the test results.

Measured results

Han EV

The high beam has a good range, but the glare control is poor. Of course, due to the function of adaptive far and near beams, the system can automatically turn off the high beams when meeting cars, and glare will not be a big problem.

Chinese DM

Adaptive high and low beams means that the high beams are turned on during daily driving, and the system will automatically switch the high beams to the low beams when passing cars or when there is a vehicle ahead. The following is the test video of Han EV/DM adaptive high and low beam.

For this function, we also tested it at night. In general, the response is very fast and sensitive, but there are false triggers. To exaggerate the situation, it would be better to make mistakes. Of course, this strategy is also correct. After all, in most cases, switching to the low beam will not affect driving safety too much, but if the vehicle is not automatically switched to the low beam, it may cause a great safety hazard.

to sum up

First of all, BYD's headlights are very beautiful, especially the design of the taillights makes people shine, and the Chinese lamp factory is well-known. The overall test data is excellent. The shortcomings such as the horizontal detection distance can be compensated by turning on the full-climate supplementary light. For example, the high beam glare problem of the Han EV can be solved by the adaptive high and low beam. Of course, on the existing basis, we also hope that BYD can apply more advanced lighting technologies such as ADB, pixel/laser light source, etc. to subsequent flagship new cars in order to reach a higher level.
