LED Belt Buckle
LED belt buckles are a fashion statement today. LED belt buckles came in to rave after it was introduced in a Hollywood flick. The LED belt buckles are designed to carry messages and also incorporate various designs or symbols. They are nothing but an array of LED's which is programmed to switch on and off in a particular sequence which creates the impression of a running program or a running message. Some of them may be static too, but then basically follow the same principle. I am describing below how it works and will be giving you a product review.
For this, a basic idea of LED will give you a suitable knowledge as to why LED's were chosen for this designing and not micro bulb. The LED is a Light Emitting Diode. The Light Emitting Diode is consisting of two semi conducting materials arranged in a way so that when a voltage potential is applied between their terminals a light is produced. This light thus produced is cool, not like the standard bulb which requires heat to produce light. This has two advantages. The first being, the chances of and LED bulb burning out are almost zero. The next advantage being that you can wear the LED near or on your body. This is not going to burn you. The light so produced in enclosed in casing of plastic. The color of the plastic determines the color of the light. Minimum amount of current is required for an LED, and so, a number of LED can run on a single AA alkaline battery. This is also another purpose why the LED is chosen for designing the belt buckle.
The LED belt buckle is considered to be the hottest fashion statement to hit the market since the introduction of the T-shirt. The belt buckle is designed for one to able to program a number of messages on the buckle for it to run on the screen. You can change the speed at which you want the message to be displayed and how it needs to be displayed. The flashing rate can also be programmed. All this is done at the touch of a button. The single AA standard alkaline battery supplied along with the belt is sufficient to run the belt buckle for duration of up to 40 hours. The messages on the buckle are visible clearly from a distance of up to 40 feet. The standard buckle measures around 5 inches in length to 2 inches in width. This is big enough for one to be able to display up to four characters.
The resolution of the LED belt buckle is determined by the number of LED's (Light emitting diodes) encompassed in a square inch. A general resolution of 7 by 24 is acceptable. This 7 means seven LED's in the vertical row and 24 LED's in the horizontal row. They are very user friendly. A number of companies manufacturers this belt buckle an abundance of which can be found on the internet.
