How to Choose Right Car LED Headlight?
Now more and more people aware of the
environment protectation, as typical representative of energy-saving in the
automotive lighting market, low carbon— car led
Headlight,quickly
became the most popular ones and explosive
growth. But many products in the market, most of them still not reliable,how to
avoid blindly follow others?Choose what kind of car led headlight can be better
option?
First of all,let’us talk about the funcation of
led headlight, it is used for car
lighting, This is also the ultimate purpose. When people talk about LED, what
is the first impression?it is
Energy-saving,
energy-saving also means lower power and lower consumption. But lower
Power does
not mean car LED headlight is not good as halogen and xenon lamps. For example,
Halogen bulbs is bigger power than HID xenon bulbs, but gradually HID xenon
bulbs replaced halogen bulbs. Why LED will be the new trend for car headlights?
Except
Energy-saving,
safe, long life, high brightness, good paving effect, the flexible application
Are the
main reason. Low power, high brightness, great light paving effect we could say
good Car led headlights.
The
Second factor are Cooling, LED will produce a lot of heat, if the heat can not
be cooling, it will cause headlight body with high temperature, and will affect
the normal life of
LED
headlight and Lumens Decay. At present, automotive led lights basically divided
into Cooling Fan structure, knit Belt Cooling, Pure aluminum cooling.
The heat comes from the LED light source, so
in order to cool the heat, at first need cooling the heat from LED chip. If
adopt fan, the bottom fan will drive air circulation, form
Convection,increased
the cooling effect. Knit Belt and Pure
Aluminum only replied on
Conducation
cooling.
Another importance factor for Cooling and
Brightness are LED chips. COB LED at the beginning very bright and bigger power
, after consist lighting on ,there are much more heat can not cool well and the brightness
decrease. Flip chip better performance than COB, but not the best. Seoul chip
good in bright and Cooling ,the best advantage are economic. Philip LED source
are best in light effect, same power, the heat will reduce 15% than same power
chip.
Then we discuss about the installation and
application issue. The space for car headlight only a little, in order to
install in, the LED headlight size can not too big to install in. Knit belt and aluminum cooling way depends on
the headlight body size, the bigger size, the better Cooling. Because of the
size , Knit belt and aluminum cooling are limited to
Develop
bigger power and more brightness. If designed the led headlights bigger power,
the size will be bigger, and not easy to installation. If it can not design
good cooling way, the light will decay and life be short. Car led headlight can not solve the cooling
issue, that is not good LED headlight,it is dangerous products,it effect
driving safety. So Fan structure cooling will be more reasonable than knit belt
and aluminum cooling.HC LED headlights use fan structure cooling and adopt good
seoul or Philips ZES chip.
Finally may all of customers choose the
Right car LED headlight.
