In 365 days and nights, the Beijing Wangfujing, which was in the middle of the night, was bleak for 30 minutes on the evening of the 23rd. On that day, the light-off action, which was based on the “Energy Saving and Emission Reduction Experience for All the Peopleâ€, was launched in eight cities across the country.
Under the background of global warming and energy crisis, building a “conservative society†is a consensus. However, this historic task of the country's survival and destiny seems to fall into the shackles of “knowing difficultiesâ€: it is said to be important, but in reality, its importance sometimes remains in words and on paper.
In fact, as a kind of social transformation, the "saving society" has the premise of success. It must first form a social value of everyone's belief. In other words, it is necessary to let the economy get rid of the utilitarian color and internalize it into the identity and needs of the society's public mind, so that the concept of saving can be truly embedded in the national system and become the lifestyle of everyone. Undoubtedly, the establishment of such social values ​​depends on persistent public education. At present, there are many gaps in such education. In some developed countries, energy-saving education runs through the entire compulsory education period from kindergarten.
In addition, the endless stream of environmental protection actions has always sounded an energy alarm for society. Environmental actions like “lights out†have already taken place in many cities around the world, from Buckingham Palace, the Eiffel Tower, the Roman amphitheatre ruins, the Athens Athens Parliament Building, to the Golden Gate Bridge, the Sydney Opera House... they have been "Lights out", expressing humanity's reflection on modern civilization and arousing people's concerns about the future of the planet.
Similarly, the lights-out of Wangfujing Street is also eager to light up the awareness of energy conservation that Beijingers lack. Due to its strong economic strength and the special status of the capital, Beijing has been in a state of peace of mind for a long time, and it rarely feels the impact of resource constraints on its own life. The price of oil has risen year by year, but it has not slowed the speed of private cars entering Beijing. The price of natural gas in Beijing is much lower than that of similar cities. The annual precipitation in Beijing is now almost the same as that in Israel, but the public does not seem to feel water-stressed. Beijing's electricity consumption is growing at a high speed, but there is almost no need to cut off electricity. The ease of life makes Beijing residents always think that the energy crisis is far away from themselves, thus lacking the necessary sense of worry.
It can be seen that the "lights out" seems to be small, but the meaning of enlightenment cannot be underestimated. We need more similar environmental actions to wake up the crisis and change our lifestyle. From this point of view, accidental energy tension is not a bad thing, but it can make people suffer from energy stress. The "light out" action has at least prompted us to reflect on the "lighting project" that has spread throughout the country in recent years and has been adopted by many cities and even some towns and towns.
Wangfujing Street turned off the lights for 30 minutes, saving 1500 degrees. Then, so many "lighting projects" and bright outdoor billboards in Beijing, what kind of energy are they using? According to reports, Beijing's high-energy lighting is a waste of a Qinshan nuclear power plant in a year. Is the night in our city so bright? Looking at the whole country, how much electricity can be saved if some unnecessary "lighting projects" are removed?
In developed countries, the concept of large-scale urbanization is being abandoned, and artificial white nights are even considered to be a kind of light pollution. In public places in Germany, it is rare for large urban landscape lighting to illuminate the night sky. Frankfurt's skyscrapers have only a few floodlights, but no one would doubt its European financial center status. Ginza is a famous commercial street in the world, but it is not as dazzling as the “lighting project†in many cities in China.
Energy conservation and emission reduction needs to start from a specific matter. Since the "Wangfujing lights out" action once again proves that the current urban lighting and conservation-oriented society concepts are not coordinated enough, then should the city government reflect deeply and timely come up with reform plans? I hope that the "light out action" can be a driving force for the government and the public to reach a consensus on energy conservation and environmental protection.

2.54mm (.100") Pin Headers
Antenk`s line of 2.54mm pitch pin headers are durably made for high vibration environments, for board-to-board or PCB to PCB Connectors, with industry-leading current of 3.0A. Designed for low-profile applications, this pin header is made from high-temperature thermoplastic and is offered with several means of connections and mounting styles such as through-hole (THM) or surface mount (SMT) and can be in vertical (straight), elevated or at a right angle configuration/orientation
Pin header customization is also available upon your request. The 2.54mm pitch pin header is highly recommendable for signal and low power PC board connections when space is at a premium and when 1.0mm and 1.27mm pitch headers cannot dissipate the required current. In addition, the 2.54mm pitch pin header holds an excellent mating quality that fits with various types of female connectors.
Applications of 2.54mm Pitch Pin Headers
Motherboard Connectors
The Motherboard of a computer holds together many of the crucial components such as the central processing unit (CPU), memory and connectors for input and output devices.
Printer Connectors
Automotive PC Connectors
Smart, high power automotive PC power supply garners its capabilities from quality pin headers, designed for general purpose battery powered applications. These are manufactured to provide power and to control the motherboards' switch based on ignition status.
Battery Connections
Rechargeable battery packs, battery balancers, battery eliminator circuits. Battery connections rely on the ability of the current to pass reliable and solid current. This prevents overheating in the circuit and voltage drop.
Medical Diagnostic and Monitoring equipment
Communications: Telecoms and Datacoms
Industrial and Automotive Control and Test
Mount Type: Through-hole vs Surface Mount
2.54mm pitch pin (male) headers are offered in either Surface-mount or Through-hole mount termination. At one side of this pin header is a series of pins which can either be mounted and soldered directly onto the surface of the PCB (SMT) or placed into drilled holes on the PCB (THM).
Through-Hole (Poke-In)
Best used for high-reliability products that require stronger connections between layers.
Aerospace and military products are most likely to require this type of mounting as these products experience extreme accelerations, collisions, or high temperatures.
Useful in test and prototyping applications that sometimes require manual adjustments and replacements.
2.54mm vertical single row header, 2.54mm vertical dual row header, 2.54mm Elevated single row pin header, 2.54mm Elevated dual row pin Header, 2.54mm Right-angle single row header and 2.54mm Right-angle dual row header are some examples of Antenk products with through-hole mount type.

Pin-Type: Vertical (Straight) and Right-Angle
2.54mm pitch headers may be further classified into pin orientation as well, such as vertical or straight male header or right-angle male header.
One side of the series of pins is connected to PCB board in which the pins can be at a right-angle to the PCB surface (usually called "straight" or [vertical") or.
Right-Angle Pin (Male) Header Orientation
Parallel to the board's surface (referred to as "right-angle" pins).
Each of these pin-types have different applications that fit with their specific configuration.
PCB Connector Stacking
Elevated Pin Header Orientation
Elevated pins aka Stacked Pins or Mezzanine are simply stacked pin headers providing an exact distance requirement between PCBs that optimizes electrical reliability and performance between PCB boards.
This type of configuration is the most common way of connecting board-to-board by a connector. First, the stacking height is calculated from one board to another and measured from the printed circuit board face to its highest insulator point above the PCB.
Single, Dual or Multiple Number of Rows
For a 1.0mm straight or vertical male pin header, the standard number of rows that Antenk offers ranges from 1 to 2 rows. However, customization can be available if 3, 4 or n number of rows is needed by the customer. Also, the number of contacts for the single row is about 2-40 pins while for dual row, the number contacts may vary from 2-80 pins.
Pin Material
The pins of the connector have been designed with copper alloy. With customer`s demand the pins can be made gold plated.
