Tell you how to choose LED car lights?

With the continuous development of technology, LED lights are not only special lights for some cars, LED lights have gradually become the mainstream lamp type of car lights.
With the advantages of novel appearance, long life, shock resistance, energy saving and environmental protection, fast response time, LED lights quickly cover the lamp modification and front installation market.
However, the prices of headlights on the market vary, and the quality is uneven. Therefore, many owners are still in a wait-and-see state for upgrading the original car halogen lights to LED lights. Because of the improper selection of headlights, it will bring a series of unnecessary troubles to the owner.
Shopping around can be understood, but due to the serious homogenization of LED lights on the market, even if the appearance is similar, the quality may be very different. Consumers buy LED lights can not just be greedy for cheap, through the price of LED lights is unreliable. Now buy LED lights on the four components of LED lights also need to be carefully screened!
1, LED lamp bead
Good LED lights use the new lamp beads and lamp bead chips supported by large light source enterprises, excellent material, advanced technology, power saving, small power loss, good color rendering, and can be used for about 5 years. Many miscellaneous LED lights because the picture is cheap, the use of inferior light beads, serious powder, power loss, power consumption, and even heat, the use of half a year will be serious color decay, leading to light not far, many LED light beads detection is normal, is not clear, is likely to be the problem of light beads.
2, heat conduction material
For LED lights, to ensure the long life of the lights, not easy to break, heat dissipation is particularly important. If the heat dissipation is not good, it will lead to light failure, can not see the road clearly, and will burn the headlights and even the headlight assembly. LED lamp thermal conductivity materials are generally aluminum and copper, copper thermal conductivity is better than aluminum, but copper is more expensive than aluminum. Most of the lights on the market use aluminum heat conduction, good lights will use copper for heat conduction, which also leads to the use of copper LED lights are more expensive. Driving at night, the headlights are our guarantee, so a good headlights are also necessary.
3, cooling fan
Some cheap LED lights use cooling fans that are not up to standard, with small wind and loud noise. Now good fans and fan ics are not cheap, in the material and IC to do something, the general consumer can not find. Cheap lights with inferior materials, in this regard to save a lot of costs. Some LED lights are very noisy when they are lit, mainly because of cutting corners on materials and materials.
4. Power controller
A good power controller can not only meet the control function of the lamp bead, but also have a good protection function for the lamp bead, which is compatible with the lamp bead, and may play the life of the lamp bead, while some cheap and obscure headlight drivers do not lead to insufficient brightness or excessive use of the lamp bead, insufficient brightness will lead to the weakening of the lamp bead, excessive brightness will lead to the lamp bead filling. It can even cause the lamp beads to burn, causing a fire. Because the cost of cheap LED lights drive power is only one-third of the cost of good lights, there are still many cheap LED lights will choose to use.
