11. Using 16 double-sided ZES-3570 lamp beads, the brightness is brighter than the original car halogen bulb, and the stable light decay is small
12. Double-effect integrated heat dissipation, built-in heat dissipation system
13. The lamp body adopts a true 1:1 design with the original halogen lamp, which is closer to the size of the original halogen bulb, making it easier to install, plug and play, and no other installation accessories are required. The surface of the lamp body is sandblasted to improve the mechanical performance of the lamp body, prevent rust and corrosion, and greatly increase the contact area between the lamp body and the outside world, accelerating the heat dissipation of the lamp body.
14. The lamp bead substrate is composed of an ultra-thick aluminum substrate, which has better thermal conductivity and achieves double-sided thermal conductivity. The substrate is closely combined with the aluminum lamp body and is in full contact, which allows the temperature of the lamp bead to be quickly and efficiently transferred to the pure aluminum lamp body, greatly improving the heat dissipation effect.
15. Built-in temperature control intelligent drive can identify the temperature of the lamp body and share the heat; avoid the risk of burning the lamp, reduce the temperature of the headlight, and extend the life.
16. The use of high-power modules can better adapt to the changes in the instantaneous starting voltage of the car, completely isolate the interference of electromagnetic waves on the car audio and driving computer, making the headlight products more stable and more efficient.
