![Why Use LED Bulbs In Projector Headlights [Expert Answer]](https://laokoonlamp.com/wp-content/uploads/2021/01/Why-Use-LED-Bulbs-In-Projector-Headlights-Expert-Answer.png)
Lamps for phase projectors are becoming increasingly important and a trend for customers. Many people now try to use LED bulbs in projector headlights, the most common and important alternative.
In the automotive industry, LEDs are the most advanced and effective lighting technology. Every type of light has its own advantages and drawbacks, so what light type should be selected if the light of the car is better for optimum light efficiency? Learn to make the right decision for your vehicle carefully.
Why use LED bulbs in projector headlights?
LEDs have been recently developed as emerging technology lamps, where vehicle LEDs light up by tiny diodes while activated current occurs instead of flashing with gas like xenon or incandescent ones like halogens.
This form of headlight consumes very little energy but can emit substantial heat on the diode.
This needs vehicle LEDs to have a lighting and other electronic component heat management device.
Not only the light output but also other electrical equipment is compromised if the device is not working properly. Car Led light is a recent concept that is being used more and more in car models.
Led lights are made up of small LEDs so they can be made in any shape. Furthermore, the type of LED headlamp light is directional rather than diffuse light, so this is a good quality headlight, although it is not as xenon in terms of luminous intensity.
Another advantage is that in only a few millionths second LEDs attain optimum visibility incredibly easily. This is why LEDs for turn signals and reverse lights are used so frequently.
They will allow other drivers to improve their response time by 30%. Any manufacturers appear to have up to 15,000 hours of LED life.

How is the LED light different from the HID light?
The two different technologies are totally different light processing processes. The HID bulb is made of inert gas, while the LED is a solid state-of-the-art technology.
HID emits a great deal of heat, and the IR and UV spectrum are very much illuminated.
The LEDs emit a fraction of the visible light spectrum and do not lose energy by the production of waste heat or electromagnetic invisibility.
There is something that is explicitly designed to unleash infrared energy (IRED), an infrared emitting diode.
The key reasons why LEDs are superior to HID lamps are power efficiency and device efficiency. Or what is the performance versus efficiency of the system? At measurement power (lumens/watt), the HID lamps are very powerful.
However, the total amount of light hitting the target area cannot be taken into consideration in this calculation.
The efficiency of the device is influenced by a variety of factors such as lack of light, safety case, and lens, operating temperatures, and energy conversion losses.
Device quality for HID lamps is usually just 25 percent better than LEDs (system efficiency is close to 50 percent of power efficiency).
Furthermore, the HID lights add several possible problems to them.
The most critical elements are repeated replacement and servicing (HID lamps have a much shorter life than LED), radioactive waste (internal mercury), and toxic emissions.
If the lamp is breached and other minor stuff like time for warm-up, failure to dim,… (UV)
LED lights are a basic innovation that has tremendous potential to boost the lighting market.
While the technology was introduced progressively, it progresses quickly and in many, if not most, implementations the market has been hit.
Detailed comparison:
#1. Temperature color (CCT)
LEDs can be used in a wide variety of color temperatures usually between 2700K and 6500K (from yellow to light blue). LEDs typically have better choices for color temperature than HIDs.
#2. Rendering of Color (CRI)
The CRI for LEDs relies heavily on that particular light. It has a broad variety of CRI values from 65-95. Generally, in the case of LPS and HPS lamps, HID lamps have standard CRI values of 0-25 and 60 for metal halide.
#3. Ability to toggle
LEDs are ideal lights to turn on and off permanently as they react fairly quickly (with no time to heat or cool). They produce steady light that does not flicker.
HID lamps require noticeable warm-up times. About half a second for car lights and minutes for stadium lights. They may also blink when the lamp has reached the end of its life.
#4. Blur
Dimming LEDs are very easy. They do this by reducing the input current.
HID lamps can be manually dimmed through the use of ballasts but the process changes the voltage input to light and can therefore alter the lighting characteristics.
#5. Level of performance
Compared to other light forms on the market, LEDs are very powerful. Power output is usually 120 lumens/watt.
HID lamps lose LED mainly due to the omnidirectional light production associated with all the losses and the need to divert them to the desired region.
The high-pressure sodium lamp with a power efficiency of 100-190 lumens/watt is by far the most powerful hidden variable.
#6. Mitigation
LED light damping is negligible, with PROTECH LEDs after 10,000 hours just 5%. HID lighting will hit up to 70 percent in 10 000 hours after high light dimming.
#7. Outputs
Without sacrificing foreign forms of radiation (IR or UV) shared with a standard light, LEDs emit a very small spectrum of visible light. Significant quantities of infrared and UV radiation are emitted by HID Lamps.
#8. Heat output
Very little heat generated by LEDs and HID lights emits a lot of heat. This may be useful in some situations, however, it’s usually not good because heat loss represents inefficiencies. The ultimate purpose of a lamp is to generate light, not heat.
#9. Duration of life
The duration of LEDs is longer than any other market light source.
Typical values may vary from 25,000 to 200,000 hours or more before a light is replaced.
The lifespan of HID lamps is good compared to some bulbs, but not to LEDs.
The normal lifetime values range from 6,000 to 24,000 hours prior to replacement of the bulb.
Note: sometimes before the end of life, an HID lamp must be changed to prevent severe color or flicker effects.
#10. Lifetime cost
LEDs have a relatively high initial cost and a low lifetime cost. Technology pays investors back in time (payback period).
The main payback comes mainly from reduced maintenance costs over time (depending on labor costs) and second from energy efficiency improvements (depending on electricity costs).
HID lamps are relatively cheap to buy but relatively expensive to maintain.
The HID bulb will likely need to be purchased multiple times and the associated labor costs will need to be paid to achieve the equivalent life of an LED.
#11. Resistance to shocks
LEDs are solid-state lights (SSLs) that are difficult to cause physical damage.
More important perhaps is, because hazardous materials such as mercury in a lot of light, the damaged HID bulb requires special handling and disposal.
The advantage of LED lights when used for projector headlights
Manufacturers have discovered a method of reconciling and encapsulating the benefits of halogen and xenon lamps in a tiny object: the LED.
In principle, because of its versatility, this light is the alternative to the mass manufacturing of projectors. However, the strongest has its own shortcomings.
It is very hard to understand how LEDs function. However, the following can be summed up. They work against electron opposition as they move a semiconductor against “holes” When such electrons become empty and merge, they appear to fuse into neutral atoms.
This process will release light energy (or electromagnetic radiation of nearby wavelengths). The method is constantly visible light repeated thousands of times per second.

The fact that LED lighting uses very little energy is one of the most significant aspects that support the producers’ hearts. The LED lights up between the halogen light and the xenon bulb in terms of brightness.
But it is more than the two above lamps in that it can take on a variety of decorative shapes. Thanks to the limited scale, manufacturers may also create their own design mark by positioning the LEDs.
All 146 bulbs are centered on the sphere reflector on the BullPro projector LED bulbs prior to exiting through the prism.
However, LEDs emit heat at the base of the light like halogen lamps, but they do not create heat when shining. The linked components can be dangerous from there.
LED headlamps, therefore, require a separate cooling system.
- Small size, compliant with projectors of all sorts
- Superior to halogen lamps but warmer than xenon lamps
- Conserve energy: with the new LED technologies at the maximum light strength, but with very little current consumption, much smaller than the standard hair bulb. Xenon is the energy form that absorbs the most.
- Do not cause heat: the two forms of xenon and the halogens are easy to damage.
- No glare: the architecture is incredibly safe and would not cause any inconvenience to the cars coming in. Cos’s a bright cut – no breach of the rule. Led bulbs are always very bright and the light efficiency on the road.
- Phase – Cos – Passing full mode with standard light distance as zin ball. Particularly a number of pins like H1 / H7 / H11 / Hb3 … only 1 brightness mode like zin.
- Light has a very good collection, just using a zin light, no need to go to a spherical mirror to collect light (like Xenon) – helps keep the zin, does not change the glare structure.
- The light collection is really strong, only with zin light, it doesn’t have to go to the spherical mirror for light collection (like xenon) – it helps to preserve zin and does not alter its composition.
- Very long lifetime, 30.000 – 50.000h norm (Halogen standard life is 500-1000h).
- With exceptionally high strength of light, the light is still steady, allowing a driver to view the road confidently, deter obstacles from afar easily, and better in the dark when going wrong routes!
- Quick and fast mounting, regular electrical ties, waterproof mounting of rubber to secure the light as completely as zin. Can be homemade automatically without specifics being added or omitted!
LED luminaires to have only one drawback: base heat generation and cable link, but by adding a separate cooling system you can solve this defect entirely.
