As a product manager engaged in LED research and development for 12 years, I told you that there is nothing impossible. Let's count the accounts for interested viewers (this time only talk about cost, not about quality and performance). The cost of a low-end circulating T8 glass tube: LED granules, Guangdong Zhongshan iron bracket + alloy line 0.2W price of 2 points (Guang Ya exhibition has seen 1 point 6, have not seen the real thing do not comment, with the pound The estimated spectral separation is problematic. Generally, a small-scale enterprise will not use it. At present, a 1.2-meter T8 lamp has a minimum of 72 (no more bright spots can be seen), totaling 1.44 yuan; A point of 3 cents / point light source components total about 1.8 yuan; circuit board according to 120 yuan / square count (do not ask whether it can pass the certification and thermal conductivity and pressure resistance, because this problem is very mentally handicapped) about 0.01 square total 1.20 Yuan; driving linear 13~18W of about 0.8 yuan / only (quality can only be haha), glass tube + powder coating about 0.6 yuan; G13 lamp holder plugs at both ends total 0.5 yuan; packaging + printing label is calculated according to 0.4 yuan Processing manual is calculated according to 0.3 yuan, totaling 5.6 yuan. Do not think about the profit according to the current market, this is not the risk of returning, of course, this is the price of the material that I know the most "economic".
You must ask the officials, plus the logistics costs, product return risk, corporate profits tend to zero, how can companies live without profit? What is the purpose of bringing products to the market at the expense of product quality and service? How long can companies continue to chase low prices? How much value can the dealers hoard?
The author analyzes that if companies do this, they will either be rich and rich, and the picture will be monopolized; or they will participate in the war in a short period of time to protect the existing market. Either way, it is a practice of killing one thousand and losing eight hundred. The price factor is just one of many factors that affect sales. More product wars, channel wars, service wars. After all, product quality is the foundation of the company. If a large number of inferior products flow to the market and end users lose confidence in the LED market, those manufacturers that adhere to high quality and high stability may have more sustainable development space.
Industrial Main Board Cable:SCSI,D-SUB,DVI,Wire to Wire ,RJ45...
There are five types of main board power line interface, and different external devices correspond to different interfaces. Different interfaces and their connecting pins are also different. For example, the pin of the main power supply is 24 pins, and the hard disk drive is 5 pins.
1. 20pin + 4Pin interface: it is a common interface combination, in which 20pin is the main power interface and 4Pin is the auxiliary power supply interface.
2. 5pinsata interface: special interface for power supply of hard disk and optical drive.
3. 6pin? PCI? Express connector: a special interface for independent graphics power supply.
4. 4Pin connector: it is a kind of floppy disk power connector, which is used to power the floppy drive equipment.
5. 4Pin power interface: optical drive, old IDE hard disk and peripheral hardware power supply interface.
