Battery Powered Alarm Clocks – Taking a Closer Look at LCD and LED Alarm Clocks
Battery alarm clocks in the market come in various shapes and sizes, but they perform only one purpose even if there are additional features. The clock’s main purpose is to wake you up on the time you programmed. In this article, we will take a look at solid display clocks like LCD and LED alarm clocks.
Most of alarm clocks I encounter nowadays are endowed with electronic capabilities and even natural sounds. I even find a talking alarm clock informing you of the time if you press one of its buttons. Others would even feature a natural sound of the wind with the alarm. O all these features, the best improvement I find with the newer clocks in particular is that they are quieter now. This is due to the development and implementation of solid state movement that is perfectly noiseless, eliminating that seemingly endless tic-tac sound. With the plenty of varieties of battery powered alarm clock that are available in the market, you have now lots of available options before deciding on shopping.
With our options nowadays, I would like to take a closer look at LCD and LED battery alarm clocks as they are gaining more popularity these days. LCD and LED clocks are known for their solid state display.
LCD stands for liquid crystal display. LCD displays are very economical in terms of power consumption. The only time this clock uses significant power is when the backlights are turned on. However, you cannot see the LCD display without a light source so it needs power when in the dark.
LED, on the other hand, stands for light emitting diode. They usually come in bright red or green or amber colors and this type of battery powered alarm clocks usually must be plugged in because LED clocks require more power to be fully functional.
With the awareness for global energy efficiency however, even battery alarm clocks are not spared from the issue especially the LCD and LED clocks. In such a case, the LCD wins the game with a more economical energy requirement. Looking at the future, there are even innovations nowadays that might eliminate the need to replace batteries and we expect them to be present in the mainstream market in the near future.
One main precaution with solid state display clocks like LED and LCD is that if your alarm clock has red digits on it; replace the alarm clock as soon as possible. Green digits are recommended as a replacement. This is because of the reason that red digits send out harmful radiation. The red lights are found to radiate through walls, ceilings, and floors. Over time, radiation from these red lights can have a harmful effect on our health.

Choosing the Best Battery Alarm Clock – Your Efficient and Reliable Alarm Clock Options

Choosing the Best Battery Alarm Clock – Your Efficient and Reliable Alarm Clock Options
Have you been in a situation where you do not have any access to AC power like when traveling or any other case and you need to wake up on time? Here is where the battery alarm clock is the best answer to this problem. This article will provide details why the battery alarm clocks are known for reliable features and will hopefully help you in choosing the best battery alarm clock by presenting the options available.
Winding up a clock and not plugging it is long over due. Before, if you missed to wind the clock before you sleep at night, then you won’t be able to get to work on time the following day. Personally, I think it is very annoying for people to wind up the clock every single day, and not to mention that some of these clocks have very irritating ticking sounds.
Now, you can already buy the best battery alarm clock with complete features while keeping it portable. It is now available in most if not all supermarkets. And this clock only requires a single battery. These battery powered clocks are energy-saving too so you don’t need to change the batteries that often. Battery alarm clocks are simply the best in terms of efficiency and reliability.
In the market, we have a variety of battery alarm clocks to select from. How can you choose the best battery alarm clock? It basically depends on the preferences but let us explore the bestseller options.
The most common and the first in the list is the traditional round clock design with the two large brass bells on top. This is perhaps the most noticeable one over the years and the one that most people have. The nice thing with recent clocks of this style is that it now became quieter and doesn’t create that loud annoying sound we hear with older alarm clocks of this design. The mechanism behind it is solid state movement which is soundless. The bell rings just the same with other traditional clocks.
If you opt for the non-traditional style, there is a wide range of alternatives to choose from. As long as solid state display is concerned, there are LED clocks and LCD clocks. To orient you, LED, or Light Emitting Diode, is one type of clock that you cannot afford to miss online or at the malls. This requires the use of electricity and it comes in bright red, green or amber colors. It must be plugged in because it consumes a large amount of power in order for it to function well. This is one disadvantage if you don’t have access to electricity for a certain period. It also is not energy efficient.
On the other hand, the LCD, or Liquid Crystal Display, is very economical and power-saving. It can only consume a significant amount of power when you turn on the back light when very dark. Its down part though is that sometimes you fail to see the LCD display when you do not have a source of light.
As far as features are concerned, there are added features like temperature readouts, automatic time adjustment, and radio receivers that can be observed with many models of battery alarm clocks. If you prefer the features with your best battery alarm clock choice, then you’ll never run out of selections.
There you have the choices with your best bets for your next alarm clocks. In conclusion, you just have to know your needs whether you prioritize style, energy efficiency, or budget in seeking that time keeper.

Quartz Battery Alarm Clock Movement – More Precise than Mechanical Alarm Clock Movement

Quartz Battery Alarm Clock Movement – More Precise than Mechanical Alarm Clock Movement
There are two kinds of movements for alarm clocks: the mechanical movement and the quartz battery alarm clock movement. These two kinds are simply limited to the traditional alarm clocks with hands, excluding the steady state LCD and LED alarm clocks.
As early as 250 BC, the Greeks already created an alarm clock prototype in the form of water clocks. They built a water clock with the raising waters keeping time and will eventually hit a mechanical bird. The bird will trigger the whistle and this resembles the modern alarm from our morning wake up clocks. This was the idea behind the concept of a mechanical clock.
The first mechanical alarm clock however waited until 1787 with the invention of Levi Hutchins from Concord, New Hampshire. The invention had a ringing bell alarm which rings exclusively at exactly 4 am and no other time is possible for alarm. Seth E. Thomas later applied for patent on a mechanical win-up alarm clock on October 24, 1876. This time, the clock can be set at any time of the day and the patent number is 183,725.
With a mechanical alarm clock, the mechanism of producing an alarm is through a main spring driving a gear which propels the clacker. This clacker will go back and forth between the two bells to produce the ring alarm. Due to the high degree of craftsmanship required with mechanical alarm clocks, these clocks are now coveted largely for display purposes and with its soon-to-be antique value.
With the demands for highly accurate measurement of time in many applications in technology, the quartz battery powered alarm clock was invented in 1929. The quartz uses a different mechanism form what was used by mechanical clocks as described above. These quartz clocks use an electronic oscillator which is regulated by a quartz crystal. This crystal oscillator drives the synchronous motor, producing a signal with very precise frequency.
The quartz clocks use quartz crystal to regulate the electric oscillator in keeping the time with much greater precision. In fact, the error with this mechanism is just less than one thousandth of a second per day. The quartz clock’s movement can gain or lose fraction of a second due to factors like friction and temperature affecting the crystal. This allows the clocks to be more accurate than the best mechanical clocks around. This more accurate and reliable mechanism is the strength of this type of movement compared to the older mechanical movement. Furthermore, they are inexpensive to manufacture. Thus, mass producing these devices was very easy hence leading the way to our homes now.
