Note items LED drive power 分類: 美容
According to the characteristics of the electricity grid, led characteristics requirements and related LED products, LED driver power to consider the following points:
General principles
 
a, according to the LED current and voltage characteristics, the ideal is to use a constant current driver. It can avoid the LED forward voltage change caused by the current changes, LED spot light a constant current at the same time so that the LED brightness stability.
 
b, In addition, LED luminous flux and inversely proportional to the temperature, so use should minimize power heating and cooling system design. Thereby reducing the working temperature of the LED.
 
c, in order to ensure the overall life of the LED must be LED thermostat control in a certain range.
 
A high reliability
 
LED products are mainly LED chips and power, cooling, housing, control circuit and other components. LED power supply a direct impact on the quality of products. LED street lamp products installed at high altitude, maintenance inconvenient, expensive maintenance.
 
2 high efficiency
 
LED energy-saving products, and drive energy-saving power supply should meet the requirements. In particular, the structure of power installed in the fixture, Floodlight Philips is particularly important. LED luminous efficiency LED temperature rise and decline. Power, high efficiency, small power depletion, heat small fixture lamps will reduce the temperature rise. Can delay benefit of LED light failure.
 
3 constant current drive mode
 
In order to meet the VI characteristics of LED, LED constant current driver power supply must be used.
 
4 Surge Protection
 
LED relatively poor impact resistance, so to enhance this protection. In particular, some outdoors products, due to the start of the grid load and Ray. Therefore, LED driving power supply to have inhibitory surge intrusion, and the ability to protect the LED without being damaged.
 
5 temperature protection function
 
Power in addition to conventional protection function, Candle Light Bulb the best increase in the constant current output LED chip temperature negative feedback to prevent the temperature of the LED chip PN Festival.
 
6 LED power life
 
Life matching and the life of the drive power of the best effort and the LED chip.
 
7 work environment
 
The various parts of the environment different to be focused on to consider LED lamps the workplace environment such as: temperature, humidity, installation location.
 
Take into account the power of work, if not the soft-start circuit energized the moment, the output will be a voltage spike. Plus the soft-start circuit, so it is necessary for the better protection of LED. That it is a key factor driving power stability.

DVD copy software 分類: 美容

The corporations, business and even home user became conscious about their data security and safety. There were two purposes why Sony and Philips introduced the DVDs in the market.reishidab5d55ck In 1995 they launched this technology for providing larger disk space and secure data transfer.

The older version of video disk was CD Video which it used analog encoding of data for transferring into CD. After that in 1993 VCD came in the market as optical disk storage. It gave data a longer life and secure travel. The optical disk also enhanced the speed of data transfer to save time of the user. VCD made its place in market rapidly. It was a cheaper way to travel almost 700 MBs of data in one disk. In 1995 DVD replaced the VCD. Earlier it was very expensive and unique technology and only businesses were able to utilize it but nowadays it is accessible by home users as well.

DVD provided larger disk storage to the user. It also secured the data travelling by giving several security tools. The data can also be copied from one DVD to other by using DVD copy software. A super drive and DVD copy software is required for the sake of writing a DVD. DVD copy software not only transfers data from DVD to DVD but also helps for computer to DVD and DVD to computer fast transfer. It enhances the data transfer speed by boosting the DVD rounds per second hence a large data of GBs gets in to the computer in a few minutes.

There are many DVD copy software prevailing in the market.dvd copying software Many large organizations are providing their tools for making DVD copies. It is a necessary tool because it gives a lot of benefits to the user. Some of these benefits are as under;

• It gives faster transfer rate as compared to normal DVD transferability.

• It secures the data by providing security tools like DVD passwords.

• It burns, rips and edits the DVD smoothly and easily.

• The DVD copy software also used for professional ripping of DVDs.

• User can add subtitles to the movies, enhance audio and video effects and manipulate the other features as per their will.

• DVD copy software also encodes the data in to non-readable format dvd to iphonefor the purpose of security and later on the same application must be used for decoding.

LED doesn't burn a filament 分類: 未分類

LED (which stands for light emitting diode) is a new form of lighting that offers immense benefits to the user and the environment.dab5d63ck Replacement bulbs of all types are now available and generally fit right back into the same socket as they were removed from.

Unlike conventional forms of lighting, LED doesn't burn a filament inside the bulb for its brightness. This burning causes heat and a majority of the energy used to power traditional lights is wasted by this heat generation.

Does the latest generation of energy-saving light bulbs really save energy?

A major study conducted by Osram, the giant German lighting company, provides evidence that they do. Until the release of the report Dec 2009 the answer remained unclear because no one knew if the production of LED lamps required more energy than needed for standard incandescent bulbs. If more energy were used in the manufacturing and distribution process, then the lighting industry would be harming not helping CO2 production.

To calculate what is known as a Life Cycle Assessment of LED lamps, Osram compared nearly every aspect of the manufacturing process, including the energy used in manufacturing the lamps in Asia and Europe, then packaging them, and transporting them to Germany for sale.

Now back to saving money...

One of the easiest things to do is get yourself into the habit of turning off appliances and lights that aren't in use. This seems obvious, but do a simple experiment of your house one night. Are the kids leaving the lights on even when they aren't in the room? Is someone taking off to go to the shops or play outside while the TV continues playing in the living room?

While you're checking out light usage, look at the wattage of the bulbs you use in the lamps and overhead lights. You can probably go down a few watts: say, from 75 to 60 without noticing it too dramatically.

But switch to LED and suddenly you can go from a 50-watt halogen bulb to a 5 or 7-watt model with very similar light output.

There is very little heat generated by LED too... (typically halogen bulbs can reach temperatures up to 320 C and have been known to cause countless fires).

This means after the switch to LED you can run AIR CONDITIONING at lower speed and higher temperatures saving even more money and CO2 gases.

If you have Halogen lights chances are you have around 50 installed in the average sized 3-bedroom house. If these run daily for around 5 hours they will cost you around $820.00 per year to run (based on a conservative rate of 0.18c per kwh). If you switched these same lights to LED they would cost you around $88 per year to run- but the real benefit is the savings over their lifetime.Typically LED runs for 50 000 hrs- that's about 12 years of savings before replacement - or about $5850 in this example.

Seek to prevail over others character easily lead to hyperte 滿足 分類: 健康

 


A recent survey found a seek to prevail over others personality risk of hypertension than other personalities.


We know that there are many factors contributing to hypertension, in addition to the patients of their disease, but also with the outside environment, living habits, diet, emotional, genetic and so has a great relationship. In those with hypertension inducement has many are preventable. A recent survey found a seek to prevail over others personality risk of hypertension than other personalities.


This is mainly because, mood changes induced by fluctuations in blood pressure, such as, intense anxiety, tension, anger, fear, terror, repression and mood swings, as well as the long-term arduous labor and excessive mental fatigue, these are the primary hypertension produced by induced factors.

When man in anger or pain, due to arterial peripheral resistance increases, the diastolic blood pressure increased significantly; fear, due to cardiac output of the blood volume increase, resulting in increased systolic blood pressure.
If patients with hypertension were some stressful conversation, you will find the blood pressure of the patients will be increased, if have been suffering from hypertension to stressful stimuli, the patient will be worse, even to the fluctuation of the transition to persistent hypertension hypertension. This shows, psychological and social factors stimulation affects people's mental state, and people's psychological condition also has a direct relationship with blood pressure. Primary hypertension formation with one's personality, emotional, seek to prevail over others, aspiring, often feel short of time and great psychological pressure on people or too honest people, timid and overcautious person, often melancholy depressed people, are more likely to suffer hypertension.
