BASIC KNOWLEDGE

The car lights are not bright enough? Do you know how they work?

Car owners usually replace the light bulb when they feel that the car lights are not bright enough. But after the replacement, they found that the bulb only brightened when it was first turned on, and then dimmed over time. How is this going on?

Today we will give you some knowledge of car lamps. In fact, the brightness of lights will slowly drop to a stable range over time. So, what is going on here?

First of all, the brightness of lights is expressed in lumens. Lumens refers to the amount of light emitted by the light source in a unit of time.

Secondly, lumens are divided into transient lumens and steady-state lumens. Transient lumens refers to the maximum brightness that can be achieved after the lights are turned on; while steady-state lumens refers to the gradual lumen value after the lights are turned on for a period of time. Steady-state lumens, by contrast, are more stable and tend to a constant value.

Therefore, the brightness of car lights changes from bright to dark, which is actually a natural phenomenon of the transition from transient lumens to steady-state lumens. So, since it is so, do you still think it’s necessary to upgrade?

If your lights are really not bright enough, for traffic safety, upgrades are still necessary. But when choosing car lights, you should also consider the steady-state lumens of the lights. In other words, the brightness of the headlights under normal conditions.

And these problems depend on the design of the product,which will affect the brightness and service life of the car lights. High-power and high-brightness car lights mean that the heat dissipation design must be optimized accordingly so that the car lights can work at a high level.
