Since the first incandescent lamp was lit by human beings, technology has kept improving, and lamps have been constantly updated. We have reached the time to truly bid farewell to the "Edison era".
A few days ago, in a small hardware store on South Inner Ring Street, Uncle Qiao, who was buying incandescent light bulbs, was a little confused. In the face of the reporter's question, he obviously did not understand: "Why not sell this kind of lamp? Small wattage is very good It ’s cheap for three dollars. I installed it on the bedside lamp and the light was not dazzling. â€Uncle Qiao did n’t know that it was last year that our country launched a road map. According to the plan, after four years, our country will No longer selling incandescent lamps.
Will eventually bid farewell to the "Edison era"
The European Union has made up its mind to "turn off" incandescent lamps, and China also launched a road map last year, clearly indicating the ultimate fate of incandescent lamps-starting from October 1 this year, China began to phase out imports in phases according to power And sales of general lighting incandescent lamps, the first retired are 100 watt and above general lighting incandescent lamps; from October 1, 2014, the import and sale of 60 watt and above general lighting incandescent lamps are prohibited; it is expected that by 2016, incandescent lamps will be completely Withdraw from the Chinese market.
The fundamental reason why incandescent lamps are discarded is that the light efficiency is very low. 95% of the electrical energy is converted into heat and wasted. This cannot be tolerated in the energy-saving and emission-reducing, green and environmentally friendly world today. Statistics show that if EU member states can fully implement the use of energy-saving lamps, they will save 80 billion kWh of electricity by the end of 2020, while China ’s total wind power generation in 2011 was 80 billion kWh.
However, the incandescent lamp is not useless, its light color and light collection performance is good, it is the most widely used electric light source. And incandescent lamps have an advantage that most other types of light-emitting products do not have, that is, they are suitable for frequent startups, such as family living rooms, toilets, kitchens, and other places, while energy-saving lamps are not suitable for frequent activation. It is said that the energy-saving lamp will consume 2 hours of electricity once turned on.
Energy-saving lamps
A few days ago, the reporter visited several large supermarkets and some building materials markets in Taiyuan City. Most of them have incandescent lamps and bulbs for sale. Supermarkets can buy incandescent lamps under 60 watts, while large-wattage incandescent lamps are still sold in the building materials market. But it can also be clearly seen that energy-saving lamps are gradually becoming the main choice in the lamp market. A variety of energy-saving lamp lamps and bulbs are available for sale. The price of the bulb ranges from a dozen yuan to thirty or forty yuan, and the brand is relatively fixed. As a rising star, although LED lamps do not occupy a major position in supermarket stores, they are highly recommended by sales personnel in the building materials market as lamps such as table lamps, ceiling lamps, and decorative light strips. LED lamps are slightly more expensive than incandescent lamps and energy-saving lamps, but the sales staff said that they have a long service life, high brightness, and low power consumption.
It seems that no matter how beautiful the past, the incandescent lamp is destined to be "deposed". In today's international and Chinese lighting market, energy-saving lamps are a widely used type of lamps. They are veritable energy-saving products. They have low power consumption and long life, and have been quickly accepted by Chinese families.
In addition to energy-saving lamps, as the industry admires, LED lamps, or light-emitting diode lamps, live up to expectations, and have emerged after energy-saving lamps with higher cost performance. The LED lamp has the advantages of high energy saving efficiency, good environmental protection effect, long service life, beautiful appearance and high luminous efficiency when the lamp is turned on. Compared with the traditional incandescent lamp, the power saving ratio of the LED lamp is as high as 90%, and its life is also an incandescent lamp. 25 times.
Now, the international community has regarded LED lights as a key development industry in the future. Not only in terms of home lighting, LED lights have more obvious development advantages in outdoor and large public places. The research and investment in LED lamps has also become a technical contest. Many well-known international manufacturers of lighting equipment have regarded LED lamps as their main research and development objects.
The ear-hook earphone refers to a kind of earphone that is added with an ear-hook on the side of the earphone for convenient use. Different from in-ear earphones, ear-hook earphones are a type of earphones and earbuds that are divided according to how they are worn. Design principle: the connection between the two units of the earphone and the wearing of the fixed beam can be canceled, with a beautiful hook to make it hang on the ear.
Advantages:
1: The way of ear hooks ensures the reliability of the user's wearing. In the design of earplugs, the unit is often enlarged to meet the needs of sound quality.
2: The design of the earhook fully demonstrates the design capabilities of the earphone manufacturer, from the design to the reliability of the wearing of the ergonomic design.
