The LED market is affected by the decline in demand in the backlight industry, and the growth of overall output value has stagnated. Apart from some niche industrial applications, automotive LEDs are one of the few market-scale and still growing applications. According to the latest research, in the second quarter of 2016, the growth of auto market in various regions of the world is slowing down. However, the trend of turning lamps from traditional bulbs to LEDs continues. More mature markets are gradually introducing high-density LEDs, and emerging countries are gradually following up. It is estimated that the LED market value of automotive exterior lighting will reach US$1.57 billion in 2016, and the compound growth rate will be 6% from 2016 to 2020.

In terms of the Chinese mainland market, the Chinese mainland's headlights still take the price as the main consideration for the introduction of LEDs. Since the LED specifications of the interior and rear lights are similar to the LEDs for lighting/backlighting, the current import ratio is over 70%, which is close to international standards. DRL (Daytime Running Light) has developed rapidly in China in recent years. Some Chinese car manufacturers have even switched to low-power LEDs for DRL applications. China's DRL penetration rate is estimated to be as high as 47% in 2016. The high-power High/LowBeam (far-and-light) is still imported mainly due to the high technical threshold, and the penetration rate is less than 3%.
The replacement of the traditional lamp light source can only be taken out from the back cover. However, in the current development of the LED light source, the original factory is mostly in the form of an integrated module, which hinders the feasibility of replacement from the back cover, so the manufacturer aims to improve the LED penetration rate of the vehicle. , began to aim at the plug-in replacement light source, becoming another trend highlight of the lights. At present, the replacement LED headlamps are mainly targeted at the PM market (retrofit market), especially in China. The replacement light source of the PM market in mainland China is currently dominated by HID (gas discharge headlamps). Since the market opportunity of replacement LED headlights is between high and low order HIDs, it is expected to erode at both ends in the future.
As the price declines and the light efficiency increases, the LED headlamp penetration rate will gradually increase, and the product positioning will gradually penetrate from the high-order to the mid-level vehicle. In addition, the emergence of replacement LED headlights will slowly change the modularity of the LED headlights in the past, cutting out more affordable LED headlight products.
In the early stage of development, the replacement LED headlights lacked perfect laws and regulations, and most of them belonged to the retail market. Consumers often took price as the main consideration when selecting. Manufacturers can produce products in the most competitive price package, but they also derived light. The problem does not conform to the regulations. Lü Lijun pointed out that although the LED light sources of various initial forms will enter the market of replacement LED headlights at the same time, in order to meet the design of the original lamp reflector structure, the future LED light source will still conform to the linear arrangement, so that the replacement LED The light source has the opportunity to shuffle the industry.
