Advancements in technology are encouraging wider
China manufacturers of vehicle lighting assemblies are adopting newer technologies as they align selections with the latest styling trends, environmental requirements and safety regulations. In doing so, companies hope to boost sales, in both traditional and emerging markets.
Under this effort, many are expanding their range of LED units, which provide more energy savings than those employing other light sources. Adoption is growing amid advancements in solid state lighting, especially in the domestic industry.
In taillights and auxiliary lamps, for example, diode-fitted designs are projected to account for more than 50 percent of output. SSL technology has taken a solid foothold in the two categories, since these require only low-power diodes, which are already available from several domestic suppliers.
Makers of vehicle interior lighting are also taking advantage of the components' availability in a wide range of hues to offer designs emitting customized colors. The current selection includes units generating blue and purple light exceeding 6,000K and 10,000K, respectively.
Solid-state devices are also gaining ground in front lighting, specifically in daytime running lamps. DRLs are considered a high-growth category, with the products now mandatory in all new cars and small delivery vans in the EU. A similar legislation will be implemented for trucks and buses in August next year.
LEDs are the preferred light source in the line because these are more energy effi cient than halogen counterparts. As a result, the additional fuel required to keep DRLs operating is minimized.
Looking to boost sales in the EU, Ningbo Yinzhou Masahiro Electron & Arts Inc. has developed models suitable for BMW cars. The products have fi ve 2 or 3W LEDs and E4 certification.
The trend for diode-based designs is also evident in headlight assemblies with angel eyes. Although CFL-fitted units dominate basic selections, those for the upscale segment combine halogen with xenon or LED bulbs.
Ningbo Yinzhou Masahiro is among the companies offering kits using SSL. Popular in the EU, especially in Germany, the maker's selection includes models that give off a cold white beam with a color temperature of 8,000K. LED bulbs reaching 10W are employed, in contrast to Taiwan- and Japan-made variants that come with 3 or 4W light sources.
Guangdong Kingwood Electronic Co. Ltd offers headlight assemblies equipped with LED DRLs and angel eyes. For the high- and low-beam lamps, the models use halogen and xenon bulbs, respectively. The products meet CE and E-Mark specifications.
A few are working on all-LED headlights. Applications remain limited to luxury vehicles, however, since the lamps require bulbs of higher power than those in DRLs and signal lights. Existing high- and low-beam lamps use two or three 15W bulbs.
Besides expanding their diode-based selections, makers of light bars are releasing assemblies fitted with a 3G security camera. The device can provide a 360-degree view of an area from a distance of 200 to 300m.
Target destinations of new designs include Europe, the Middle East, South America and Africa.
