Energy-saving service companies sign energy-saving service contracts with owners to provide them with a complete set of energy-saving services including energy audit, project design, project financing, equipment procurement, project construction, equipment installation and commissioning, personnel training, energy saving confirmation and assurance, and A commercial operation mode that recovers investment and profits from the energy-saving benefits obtained by customers after energy-saving transformation.
"The essence of contract energy management is to use the reduced energy cost to pay for the energy-saving investment method for the full cost of energy-saving projects." Zhang Dongsheng, vice president of the Guangzhou Lighting Association, briefed the reporter.
It is understood that the contract energy management cooperation model is usually divided into two types: First, the annual savings in electricity costs, divided by the proportion of the energy-saving transformation of the two parties, return year after year, until the completion of the contract stipulated amount, the contract implementation cycle longer; second is the annual The saved electricity fee is returned to the LED company in full, up to the agreed amount of the contract. This model has a fast payback and is favored by LED companies.
"If the energy management model is really carried out according to the contract, the company providing LED services is also profitable. However, the facts are not as smooth as expected." Zhang Dongsheng disclosed to reporters that the success rate of contract energy management in our province is only 5%.10 %. Among them, private enterprises are better promoted, and state-owned enterprises are relatively difficult.
Due to its high price, LED lighting products have encountered bottlenecks in the process of widespread promotion. According to Zhang Dongsheng, a 1.2-meter-long light pipe requires 278 chips. If the price of a chip is calculated on the basis of the price quoted by the chip maker Cree, a lamp requires nearly 300 yuan. The ordinary energy-saving lamps only need tens of dollars.
Zhang Dongsheng said in an interview with reporters that although China's LED product manufacturing capacity accounts for 50% of the world, but the profit is the lowest link. The core technology for the production of LED products is in foreign countries, which is the main factor that affects the price of products. Second, there are factors such as high production costs and lack of national standards.
According to statistics, currently there are more than 2,400 enterprises engaged in LED in China. Unfortunately, application products and supporting enterprises accounted for the vast majority, with over 1,700; followed by packaging companies, about 600; the least are companies engaged in epitaxial growth, chip manufacturing, research institutions and manufacturing enterprises. In total there are only 40.
Some companies have lost the incentive to retrofit LED applications because of the high LED cost. For this reason, contract energy management came into being, but its promotion is not optimistic.
Future Bus connectors Description
Future Bus connectors, which use 2mm style have a mating distance of 10mm. Both Future bus and the upgrade Future bus+ are out-dated.No additional work has been done to upgrade the specification over the years. However we still produce products which meet the Physical and Electrical layers of IEE P896.
Antenk future bus connecto feature
designed in metric dirnension on 2 millimeters grid over 5 rows.
1 Standardized product through EIA (USA), IEC and CECC (international).
2 Selected by IEEE as the interconnection system for Futurebus + / SCI / VicBus.
3 Multi-sources product,use for telecommunication, network, server / workstation market.
4 High tempersture materials SMT compatible.
5 Modular design giving flexibility for system design.
6 Stackable end to end without loss of contact position.
7 High density (more than 2 times as compared to the standard inch based " Euroconnector DIN 41612" ).
8 Tuning Fork female contact concept for higher robustness and improved reliability
(low contact resistance and high normal force).
9 Low insertion force design.
10 Inverse connector system (signal and power).
11 Optimized solder and compliant press-fit terminations for backplane and circuit board connectors.
12 differents mating lengths on signal and 3 on power for standard connector system.

2mm HM (hardmetric) Connector Introduction
System designed to meet the current and future needs of instrumentation applications giving excellent electrical and mechanical characteristics. It is a high performance, high density system with flexible configuration which offers upgradeability. The connector system is fully supported by Antenk spice models to guarantee choosing the right product to match the application.
ANTENK 2.0mm HARD METRIC CONNECTOR MODULES comply with international IEC 917and IEC 61076-4-101
standards. The connector systems in telecommunication and other industries require hight density connectors to support
larger amounts of data increasingly higher speeds antenk 2mm hardmetric modules offer the solution
Features and Benefits:
This high density connector modules can be stacked end to end without loss of space.
1,ANTENK developed the 2.0mm series under thorough consideration of impedance match, propagation delay,
cross talk, reflection. It is the ideal connector for digital high speed data application.
2,ANTENK offers differend types with inverted mating configuration. The male connector is a fixed module at the
backplane and the female commector is a free component of the plug-in module. The male connector has 5 signal row.
3 The outer shielding rows z and f of the male connector engage the shielding contacts of the famale connector. theshield
is also designed for gas tight, press-fit installation.
4 The connector system offers 15 contact length that utilize the proven press-fit assembly technique. Within the 15
contact length are 3 mating levels, achievable on both the plug-in and rear I / 0 side.
5 Coding system prevents mix-up and wrong mating between male and female connectors.
6 The 2.0mm hard metric connectors and DIN 41612 connectors can be used on the same PC board as both have the
same mating distance.
7 Staggered make-break pin populations for optional hot-swap capability.
8 Rear pin option for through-the-backplane I/O application.
9 High density PCI capability,shield for EMI/RFI protection.
