LED headlights have many benefits for your vehicle, such as better lighting, longer lifespan, and lower energy consumption. There are many brands of LED car bulbs in the market, such as high power or low power, expensive or low cost. How to find good LED headlight bulbs for cars? What are the 5 important points when selecting LED headlight bulbs for a car? Let’s know.
1. LED Brightness
The brightness and lightness of the bulbs play a very important role. A good and bright bulb gives better visibility while driving at night. The brightness of LED headlights also depends on the wattage of the bulb. A wattage diode emits about 130 lumens. The lumen higher rating, the brighter the bulbs will appear. The price of headlight bulbs depends on their brightness; the more brightness, the higher the price. These headlights are more helpful for people who have difficulty seeing at night.
“Lumen” is a standard unit of brightness measurement. Most LEDs range between 8,000 and 13,000 lumens. Total Lumens is widely used by manufacturers during the design of LED bulbs and is often measured with an integrating sphere after the bulb is manufactured. H11 LED Headlight also produce more light than halogen lights while consuming less energy. This improved efficiency can help your car, truck, or SUV conserve more fuel.
2. LED Radiation Characteristics
Different LED light chips come with various LED beads in various configurations. All of these will change the pattern of the light beam. Quality LED light chips are designed to resemble the original filament, and the distance between the beads on either side should be as near to that width as is practical.
Looking at the LED headlamp in the two images above, it is clear that its footprint and the area between its two sides are excessively large. Your beam pattern will be out of focus with no hot spot if you have spaced out too far, which will cause glare to other drivers. The NAOEVO S3 LED’s headlamp conversion kit is a fantastic example. Due to the incredibly thin metal between each LED, the LED position can be as close to the original halogen position as is practical.
3. What Color Temperature is Better for Driving?
Does every light have a color temperature? The Color temperature is measured in units called “kelvins.” You can tell by the lower Kelvin rating that yellow or orange light has, which is called a warmer color temperature. A higher Kelvin rating means whiter and more blue light. It shows a cool temperature.
Colors are different for everyone. A natural resource of light during the day is a high color temperature. It makes the human brain more energetic, and such high-color temperature light helps reduce eye strain.
Typically, sunlight is measured as a 5800K color temperature. While it’s close to 6000K daylight, it provides a noticeable difference in brightness that communicates excellent driving performance. Therefore, the LED’s headlight bulbs in the market that emit 5500-6500K color temperature are better for night driving.
4. The Best Light Beam Patterns
Light beam pattern refers to the angle, or shape, of the light emitted by the headlight housing. Light beam patterns are very important to a vehicle. Quality LED’s headlight bulbs are designed to emit a 45-degree cut-off line on the low beam and focus on the high beam. Using a low beam in an area that is not dark has two main advantages. First, they help to see oncoming traffic clearly without blinding the eyes of other drivers.
Second, better light beams help drivers have a wider vision when driving at night. They can see clearly on both sides of the road and react quickly to an accident. In some right-hand drive countries, the light beam pattern should be lower on the left and higher on the right.
5. LED Headlight Bulb Age
LED light bulbs generate more heat. They try to produce bright light by using a lot of energy. Yes, LED headlight bulbs have poor heat dissipation, but their brightness is excellent. When the LED headlights work, the complex circuit board generates most of the heat based on the diodes.
There are three heat dissipation methods for LED headlights: 1. Pure aluminum heatsink 2. Fan cooling 3. Copper tape cooling. There are three basic theoretical methods of heat dissipation: 1. Conduction, 2. Convection 3. Radiation
Aluminum is used to make LED headlight bulbs with heatsinks constructed entirely of aluminum. Using its thermal radiation, it aids in cooling the bulb. The cooling capacity of this fanless LED headlight bulb with a pure aluminum heatsink remains constant. However, the bulb power should be kept as low as possible because this would also limit the brightness. Copper wire with a tin coating makes the heatsink on LED headlight lights. The area available for heat dissipation can be increased by adjusting copper tape fins and fins.
The choice of lights proves safer because of their improved visibility. LED car lights don’t generate as much heat, and LEDs last much longer than other types of light. Unlike incandescent bulbs, LEDs do not burn out like them.
