How to Choose an Energy Saving Lamp

Energy saving lamp is also called compact fluorescent lamp। In addition to white (cold) light, there is still yellow (warm) light. In general, in the same watt situation, an energy saving lamp can save 80 percent energy of incandescent lamp and only 20 percent thermal radiation. In normal condition, a 5 watts energy saving lamp is equivalent to 25 watts incandescent lamp and 7 watts is equivalent to 40 watts.

It is first invented by foreign manufacturers in 1978। Because of high efficiency (5 times than ordinary light bulb), significant energy saving, long life (8 times than ordinary light bulb), small size and easy to apply, it is popular with people and countries। Now, many families have already used the lamp। So, how do consumers distinguish the quality of it? Following below:

1. Select the products with safety certificate, whose quality can be guaranteed.

2. The packing should be fine and beautifully printed. Name, address, telephone number, complete instructions and other information are complete. Check the appearance of light and its plastic part should be marked clearly the source (it may be a trademark or name of manufacturer), rated voltage and voltage range, rated power and rated frequency;bulbs should be smooth, no bubbles;phosphor coating inside the lamp should be fine, no granule and uniformly white;lamps and plastic parts should be securely connected, not loose;no sound when hand shaking the whole lamp.

3. The plastic case must be made from specific engineering plastic and ordinary plastic is banned for production. In addition, compare lights and choose with good consistency in shape and size. Meanwhile, The shell can not be cracked and loose.

4.Booster available is the best when purchase. Regulate the booster to 150V (or the minimum voltage marked on the instruction) and equip with an energy saving lamp,then it should be able to pass once when power is on. Because energy saving lamp starts with two characteristics:First, the higher the temperature is, the easier to start;Second, it is easily started under the effect of human body. It is worth mentioning that there should be about 0.4 second start delayed time after setting up the filament preheating circuit inside a lamp.

5. Electromagnetic compatibility is the necessary performance of household appliances. When you buy, examine whether it is through the test.

6. The temperature of energy saving light rises slowly in normal state, otherwise, its life will be short. Meanwhile, both ends are black or filament is red or flashing when the lamp is on shows it has quality problems.

7. Purchasing the energy saving lamp, you can only consider the price, regardless of quality. If blind pursuing low price, it is very likely to buy substandard products.

What if The World Without Google?

Google,no doubt one of the world's best known companies.It not only allows people to freely access information and give reasons for the existence of e-commerce,the most important thing is that it proves to the world:free of charge can earn!Perhaps all these make you more like to know - what if the world without Google?

There may be a number of assumptions:Perhaps Microsoft will even worse off than today? Maybe Apple will bankrupt? yahoo is no longer be the world's most powerful company? What the world will be without google?

Yahoo:
You can not forget it - as Google's biggest rivals,yahoo has now been thrown far behind.It has all:adequate capital,a broad user base,a strong business.It really needs is a leader in insight to lead it to success.

If without Google,Yahoo,entirely possibly has a huge space for development in the Internet field,and eventually become the most influential Internet companies - not Microsoft or Google.But,in fact, because Jerry Yang(Yahoo's founder)'sindecisive, Yahoo prosperity will not be renewed once already.Even in the fierce competition,Yahoo has not taken measures to improve itself.

This gives us reasons to believe:even if there is not Google,the other competitors will beat Yahoo.Perhaps this is the fate of Yahoo.

Microsoft:

If Google is the end of the tunnel of light,Microsoft is among the darkness of the tunnel - the ubiquitous,but difficult to detect.If not Google,open source software will not come,Windows operating system are still powerful than ever before,desktop software will be always important.In addition,Microsoft will be fiercely compete with Yahoo on the online advertising and cloud computing.

However,Google has brought the concept of cloud computing and develop a rich services based on cloud computing.If any services can be achieved in the clouds, desktop applications will be replaced by clouds,which will direct threat to the Window operating system dominance.Microsoft also had to face Google,seen from the launch of the online version of Word and Windows Azure.

But we can clearly see that: Google has been to avoid direct invasion of Microsoft's core territory.Over the years,until recently with the development of Chrome OS and Google Android was launched to challenge Microsoft.

Perhaps you might want other competitors to challenge Microsoft.However,who will be such capital in addition to Google?

Apple:

Speaking of the Internet,maybe you must mention Apple.Because Apple has become strong enough.In the field of mobile phone operating system,Google and Apple's competition is perhaps the most eye-catching.People are always very keen to compare Android and iOS.But we think:If there is no Google Maps,YouTube and the Web-based universal application,application of iPhone will be freezing. Perhaps iPhone will lose the important competition bargaining chip with BlackBerry and Windows Mobile.

In all,what google gives us is far beyond the above.If without Google,our lifestyle will change.So we thank Google for the free information,and rich applications.It also embody the leadership of Google for Internet.

Knowledge of Office Lighting Environment

Natural light and artificial light intensity,color in office directly affect the vision organ of staff,then on morale,and work efficiency.In order to effectively control the office lighting environment,enterprises should note the following:

1.Correctlt choosing lighting methods

According to the nature of work and workplace,correct choose lighting means correctly to not only help to improve the lighting effects,but reduce the lighting investment and day to daily expenses.

2.Correctly choosing light source

Using natural light source as possible as you can in the office,which helps save energy and cost,more importantly,natural light is bright and soft,having a good effect on the physiology of human body.Artificial light should be only used as supplementary light sources,combined with natural light.

3.preventing glare

When too much brightness or excessive brightness ratio in the field of vision so that people feel dazzling,this is the glare.Measures to prevent glare is mainly restricted source brightness;reasonable distribute light sources,raising environmental brightness and reducing the brightness ratio.

4.let uniform illumination

Reasonably arrange lamps so that illumination is nearly uniform.

Flashlight With Clip

Compare to the general single direction flashlight,this multi-functional led flashlight allows you to use more convenient.This new flashlight lamp has two axis device,and you can freely adjust the lighting direction.At the same time,its unique handle can serve as a cramp to fix flashlight,and can also open as a support as well.This compact design is so close to life that emergency lighting has become more convenient.

Iphone 4 Flashlight Software Was Finally Approved

Apple iPhone 4 leads a comprehensive improvement on the camera features,joining the LED flash/fill light the first time,in addition to new light-sensitive and back-illuminated CMOS devices with 5 million pixels.It can be opened when taking pictures or shooting videos.Soon,the developer says,why not use it as a flashlight?

In the original,there are a lot of iPhone flashlight softwares at app online software store,but before the release of the iPhone 4,the principle of the software is transferring to the iPhone screen for maximum brightness to light,and the effect is not ideal,coming out power consumption increases and battery life shorten situations.

As the program of LED flashlight software actually is very simple.So the next day when iPhone 4 listed,Developer"MoreBluSky "submitted their software:Flashlight - For iPhone 4.Before and after this,there are many software developers to submit a similar software products.

But more than a week later,these software are not approved.MoreBluSky Contact Apple official and ask the reason,the result is "improper use of hardware".

Finally today,Flashlight - For iPhone 4 and similar iPhone 4 LED Flashlight softwares are approved in the App Store for online sale.Based on Apple's request,the softwares added in instructions such warnings:sustainable use of iPhone LED will significantly shorten the battery life.

China Tea

According to a lot of physical evidences and historical data,it shows that,in other parts of the world,tea drinking habits are from China.So people generally agree that tea first appears in China,the rest of the world's tea drinking habit and cultivation is directly or indirectly from past China.Tea making and the earliest record of tea were all in China,and the first tea product are also in China.In a word,according to reliable archaeological data,China is the true birthplace of tea.

Tea,belong to theaceae,is the evergreen shrub or small tree plants,and planting up to 1-6 meters.Tea trees like humid climate,which are widely cultivated in the south area of Yangtze River in China.Tea made from tea leaves,soaked in water before use,has a strong heart,diuretic effect.Tea leaves planting for 3 years can be taken.Usually,picking up 4 or 5 buds before and after the Ching Ming festival(Chinese festival),tea produced by these buds is very good quality tea,belonging to the treasure of tea.Tea originated in China,and China has a long history of tea-drinking record,which can be traced to the earliest Stone Age about Yan.

EVA

Ethylene Vinyl Acetate (also known as EVA) is the ofethylene vinyl acetate copolymer. The weight percent of vinyl acetate usually varies from 10-40% with the rest of ethylene.

It is a polymer that approaches elastomeric materials in softness and flexibility, however, can be processed like other thermoplastics. The material has good clarity and gloss, barrier properties, resistance to low temperatures, stress-crack resistance, hot-melt water-proof properties, and resistance to UV radiation. EVA has little or no odor and is competitive with rubber and vinyl products in many electrical applications.
