With the trend of miniaturization and low power consumption of electronic products, it is imperative that end product manufacturers have proposed miniaturization requirements for various components, and LEDs are no exception.
The Chinese government has increased its support and promoted the sustained and rapid development of the LED industry. The continuous support of the policy and the growing demand of the market have made the LED industry brighter in the future.
As the world's most watched new generation of light source, LED is known as the most promising green lighting source in the 21st century due to its high brightness, low heat, long life, non-toxic, recyclable and other advantages. China's LED industry started in the 1970s. After nearly 40 years of development, China has become the world's largest producer of lighting appliances and the second largest exporter of lighting appliances.
The main characteristics of China's LED industry in 2013 are: the rapid growth of semiconductor lighting market demand has driven the active industrial chain; the changes in market demand have accelerated the pace of technological innovation, and the joint innovation of the industry chain has become a consensus; the utilization rate of LED chips has gradually increased. The price has further declined; the alliance, mergers and acquisitions and restructuring of enterprises have become increasingly active; lighting companies have paid more attention to the construction of sales channels, preparing for the large-scale start-up of the semiconductor lighting market.
Since the second quarter of this year, the domestic semiconductor lighting market demand exceeded expectations and continued to grow rapidly, driving the simultaneous growth of LED devices, related materials and equipment markets. Some enterprises even experienced queue queuing that was rare in previous years. The rapid growth of domestic semiconductor lighting market demand is a major factor in the overall improvement of industrial development, and export growth is more obvious.
The market space created by LEDs replacing traditional lighting is huge, which will make China's semiconductor lighting market maintain a high-speed and steady growth in the next few years. The main performance characteristics have four aspects.
First, reducing the cost of lamps is the focus of semiconductor lighting development. One of the biggest problems that hinder the popularity of LED lamps is cost. The cost of LED lamps is 3-5 times that of fluorescent lamps and HID devices. The reason for the high cost is the price of the unit light and the peripheral components. It also needs to drive peripheral components such as power supply, heat dissipation and lens. Therefore, to reduce the cost of the product is not only to reduce the cost of the light source, but also to reduce the cost of peripheral components. In addition, indoor lighting attaches great importance to color temperature and color rendering, so improving light quality is also the focus of promoting LED lighting applications in indoor lighting.
Second, the demand for power-type, surface-mount LEDs is growing rapidly With the gradual launch of the functional lighting market, the demand for power-type and surface-mount LED products is growing rapidly. In addition, the increasing application ratio of LEDs in automotive lamp products will also drive demand for the power and surface mount LED industries. Driven by downstream market demand, power and surface mount LED products will become one of the key development products of the company.
Third, the product to diversified application areas to expand LED applications are gradually moving from simple decorative lighting, to high-power urban landscape lighting, municipal road lighting, automotive lighting and industrial lighting-based functional lighting products, and gradually meet the high-speed Highways, tunnels, subways, airports, shipping, etc. require high market demand for the reliability of lighting products.
Fourth, LED products tend to be miniaturized and integrated With the trend of miniaturization and low power consumption of electronic products, it is imperative that end product manufacturers have proposed miniaturization requirements for various components, and LEDs are no exception. At present, with the continuous improvement of power and brightness of single LED chips, semiconductor lighting products suppliers are actively developing LED products with more advantages in terms of continuous optimization of heat dissipation technology. The miniaturization and integration of semiconductor lighting products have been Become a development direction. For example, portable lighting products that previously used 8-12 LED dies have only used 1-3 high-power LED dies to achieve better lighting.
Our company produces a vary of specifications of glass particles and glass-lumps which can be used in ordinary pavement of road to shorten braking distance effectively, to improve the warning role and to decelerate in advance to achieve safety. Pavement laid with this product will not peel off and maintain function well after a long time wheel friction.
It is also used in the decoration of building outer-walls and all kinds of ceramic. There is mainly 1-2 mm, 2-3 mm, 3-4 mm, 600-850 microns, 300-600 microns, 180-300, and less than 180 microns etc. as well customized specifications customers require.
The glass bead can be produced based on the standard of countries or areas, such as EN1423/1424, AASHTO M247, BS6088, JIS R3301 and KS L2521 etc.
