1. Overview: 2. Research Background: Automobile headlamp reflectors experience high temperatures due to heat generated by the lamp and their sealed structure. These high temperatures reduce light output and shorten lamp lifespan, potentially causing thermal shock deformation in nearby components. While previous research has investigated various aspects of LED lamp design and heat dissipation, including
1. Overview: 2. Research Background: LEDs are increasingly used due to their long lifespan and high efficiency. However, LEDs are point heat sources, leading to localized temperature increases in the surrounding polymer molding material, peripheral devices, and the LED element itself. This temperature rise negatively impacts luminous efficiency (a 5-8% decrease for every 10°C increase),

1. Overview: 2. Background: Automotive headlamps are crucial for nighttime safety and vehicle aesthetics. Historically, halogen and xenon bulbs were prevalent, but halogen bulbs are inefficient, generating significant heat, while xenon bulbs have slower ignition times. High-Power Light Emitting Diodes (HPLEDs) offer higher efficiency and longer lifespans, but their compact size leads to high junction
1. Overview: 2. Research Background: Automotive headlamps are crucial for driver visibility, and LED lamps are gaining popularity due to their energy efficiency and long lifespan. However, the high heat generation of LED lamps can reduce their lifespan and efficiency. Existing water-cooled cooling plates and heat pipes offer superior cooling performance but are limited by
1. Overview: 2. Background: High-brightness white light-emitting diodes (LEDs) are very promising in many new illumination applications. LED light sources offer advantages such as long lifespan, fast response speed, environmental friendliness (mercury-free), and a color temperature (5500K-6000K) closer to natural light than xenon sources (4000K). The increasing use of LEDs in automotive lighting (interior lights,
