Hongli Optoelectronics pushes high-reliability and high-light output density for automotive LED light source C2525

Based on the high standard requirements of automotive lamps for LED components, the market pays more attention to the reliability and stability of automotive light source products introduced by domestic packaging manufacturers. Recently, Hongli Optoelectronics has launched C2525, a vehicle LED light source with high reliability and high light output density.

The high-power ceramic packaging product is a mature LED packaging technology product of Hongli Optoelectronics. It adopts a new white light packaging technology to ensure the uniformity of the color of the product. Among them, Baiguang C3535 has obtained a third-party LM-80 6000 hour test report, which guarantees a good service life and luminous flux maintenance rate. The C2525 package is smaller in size, which is more conducive to luminaire design and secondary optical design; it has a higher light output density. This eutectic-based ceramic LED package device is highly reliable and efficient, meeting the harsher automotive lighting environment requirements.

In order to verify whether the product can meet the high standard requirements of automotive lighting, Hongli Optoelectronics invited the LED-FPD Engineering Technology Research and Development Center of Hong Kong University of Science and Technology of Foshan as a third-party testing agency to conduct data testing on the company's C2525 sample, and an international The first-line brand of the same type 2525 optoelectronic products (hereinafter referred to as "brand C") joined the evaluation to show the market's technical strength and product competitive advantage in the automotive lighting field. (The following information is from a third-party assessment report)

Transient photoelectric parameter

Let's first take a look at the transient parameters of the voltage, luminous flux, luminous efficacy, color temperature and color rendering index of Hongli Optoelectronics and Brand C at a current value of 350 mA. In order to compare each of our product models, five different numbers of samples were selected for testing.

From the test data, the sample of Hongli Optoelectronics and the sample of brand C, the transient photoelectric parameters are basically kept at the same level, even slightly more prominent in the light effect and index.

The eutectic process uses a plurality of metals to melt at a eutectic temperature to form a eutectic alloy, thereby soldering the LED chip on a substrate or a support. The high-power LED device using the eutectic process can meet the requirements of a more severe use environment in the automobile. Wide range of applications in lighting and other fields. We can reflect the stability and reliability of the welding process through the test of eutectic voids.

The detection accuracy of this X-Ray inspection equipment is 1um. From the picture, the eutectic welding performance is basically good and the void is small. Moreover, it can be seen that the eutectic soldering area at the edge of the chip is large, and the relative heat dissipation is also better.
