The complete value chain includes seven major links: technology research and development, raw material procurement, logistics supply, processing and assembly, order processing, marketing and branding. Generally speaking, the added value in the industrial chain is connected into a line, which can form a symmetrical “smile†shape, hence the name “smile curveâ€. The value-added technology at the front end of the value chain and the brand service at the back end have the highest added value. The intermediate processing assembly has the lowest added value. The led industry value chain includes seven major links: epitaxial film design and development, single-chip design and development, material procurement such as epitaxial wafer, chip processing, packaging and testing, led application, and brand service.
From the perspective of the development of China's LED industry, the value-added curve of China's LED industry value chain is not a relatively symmetrical "smile curve", but an asymmetric "smile curve", or "long tail curve". The led industry belongs to high-tech The high-tech content of the technology industry determines the high added value of LED epitaxial wafers, LED chip design and development and processing links to a certain extent. In China's LED industry chain, led epitaxial wafers and led chips account for about 70% of the industry's profits, led packaging is about 10% -20%, led applications are about 10% -20%. LED epitaxial wafers and led chip design at the front end of the value chain. R & D and processing occupies a very high added value; the LED application and brand service at the back end of the value chain are slow due to the slow construction of the led wholesale agent channel and low added value. In this way, the front end, the back end of the value chain and the packaging test at the lower end of the value chain are connected into a curve. The curve does not form a relatively symmetrical "smile curve" but a "long tail curve".
In the design and development of epitaxial wafers and single-chip design and development, China's LED companies are in an absolutely weak competitive position. However, Japanese and American companies rely on the monopoly advantage of technical patents to increase the added value of technology R&D, which leads to the high added value of the front end of China's LED industry value chain (the profit is almost occupied by Japanese and American companies). Therefore, most of the LED companies that rely on imported technology patents in China face extremely high technical costs. The market can accept the price of led products is limited. However, this is not the main reason. The current competitive landscape of China's LED industry is the main reason for the “long tail curve†of the value-added curve of the LED industry. In the fierce competition environment, domestic led companies mostly use price wars in order to penetrate into the LED application market. Eventually the LED application and package test added value is compressed and its profit margin is suppressed. In addition, the development of China's LED industry is not yet mature, the brand operation and service marketing capability of led enterprises are relatively low, and the added value of brand services is relatively low.
The development of the domestic LED industry chain from the "long tail curve" to the "smile curve" is the goal of the current LED industry, and the only way is to change! Enterprises must be highly focused on the development trend of the industry, industry boundary dynamics and industrial upgrading. China's LED application market has great potential, and LED will be widely used in large display, mobile phone display, TV display, car lighting, landscape lighting, commercial lighting, home lighting, traffic lights and other fields. This means that China's LED application market has great potential, and the added value of led applications will be greatly improved. With the continuous expansion of the LED application market in China, on the one hand, more and more powerful enterprises have entered the LED epitaxial wafer, single-chip technology research and development and processing; on the other hand, the added value of led applications and brand services are highlighted. Domestic LED manufacturers have joined the technology R&D competition, which may break the technical blockade of Japanese and American companies, and reduce the added value of LED epitaxial wafers and single-chip technology R&D and processing links to a reasonable level. As China's led enterprise market control ability increases, the added value of led applications and brand services will inevitably rise. Therefore, the value-added curve of China's LED industry value chain must develop from the "long tail curve" to the "smile curve".
Introduction
BMI(Body Mass Index) is a person's weight in kilograms divided by the square of height in meters.
In general, BMI is an inexpensive and easy-to-perform method of screening for weight category, for example underweight, normal or healthy weight, overweight, and obesity.
About Materials and Shape of Case
The BMI calculator is ABS case, PVC coated fiberglass tape.
BMI tape measure has several kinds of case shapes-round shape, heart shape, and drip shape. Today we will introduce this round and biggest one for you.
About Language Version of Wheel Plate
This is the most popular English version.
We have Spanish version and other language versions.
About Tape Sizes
The tape both sides with 150cm, one side for male and the other side for female.
To check your waist size, the tape marked with 3 colors zones (green for healthy, orange for over weight, red for over obese)
There are 2 widths for the tapelines: 13mm and 7.5mm
On the case, there is a wheel which can be rotate. Body height data in cm and inch marked on wheel, and weight data on the case, when we rotate the wheel, we can match the height and weight, then check the BMI arrow point to which section(there are 5 sections:underweight,healthy,overweight,obese and very obese)
For example, you are 160cm height and weight 55kgs, match them, then check the BMI arrow point to healthy.
BMI Categories
Less than 20: Underweight
From 20 to 25: HEALTHY
From 25 to 30: OVERWEIGHT
From 30 to 40: OBESE
More than 40: VERYOBESE
