    Coming Up Soon,
    LED Fluorescent Lamp

    There are some changes in sign market to change fluorescent lamp to LED module in Flex sign. Moreover, there is LED fluorescent lamp which is as same as the existing fluorescent lamps even in terms of the shape. LED Fluorescent Lamp, let? find out how it meets customers?needs.



    New technology for flex sign and replacement of fluorescent lamp in LED market.
    Fluorescent lamp has been loved for a long time by most of customers because of its features such as easy installation, reasonable price and convenient availability. But because of some disadvantages like black spot symptom, short life cycle, limited color options, and shape concern, and so on, fluorescent lamp has to be replaced frequently and it has mercury against the contemporary environmental paradigm. With those reasons, other lighting sources are taking fluorescent lamp? market share.
    LED Fluorescent Lamp was first introduced on September 2007 through our magazine and it successfully hit the sign market. Still LED Fluorescent Lamp needs developing in some details. Using lots of LED modules leads cost pressure and installation is not easy like the conventional fluorescent.
    Some companies in sign industry launched flex sign by adopting LED at an exhibition in last year. Those flex signs were used not only for front sign but also both side sign for projecting sign and it was not shown before.
    Some say that ?here have been attempts to adopt LED to flex signs but there were still some problems such as price, installation and illumination. However, we expect that the LED Fluorescent Lamp will be percolated into the market soon with its properly useful applications because technology improvement is getting advanced.?orea Photonics Technology Institute(KOPTI) also gives an impetus to develop not only an optical communication and camera module for mobile phone but also LED module for sign applications. Recently, a sign company has launched LED Fluorescent Lamp which may supplement some weak points of the conventional fluorescent lamp and leave strong points. Its shape is as same as the conventional fluorescent lamp.
    But light emitting methods are different between LED Fluorescent lamp and fluorescent lamp. Normally, conventional fluorescent lamp emits light by changing ultraviolet ray to visible ray with mercury discharge but LED fluorescent lamp uses LED itself.

    To improve lens is a main factor for a diffusion of light and light heading straight.
    Is it a fluorescent lamp? It was LED fluorescent lamp with fluorescent lamp shape after a close look and we could notice it by its slightly different color. Even though LED color is white, there are various kinds of LED colors such as blue-white, yellow-white, etc. This time, this lamp was used blue-white LED. In fact, LED fluorescent lamp was developed to replace fluorescent lamp.
    Does the same shape mean the same function? The questions on LED are getting bigger and bigger if LED fluorescent lamp has fixed problems about price, light nature to go straight, not brighter than fluorescent lamp and user-friendly usage. For example, can LED fluorescent lamp replace fluorescent lamp for flex sign when fluorescent lamp is out of order?
    LED? brightness is 200 luxes with 2 meter standard distance while fluorescent lamp? is 400lux. LED fluorescent lamp is still waiting to show in the market until Lens?performance is improved which is core part and takes brightness in LED.
    There are two types of LED module which one is Oval type LED(or Deep type) by using its lens and the other is SMD type without using lens. Oval type LED can transfer light further than SMD type but it is not brighter than SMD type. SMD type is being applied to most of channel signs as it is excellent with diffusion of light and strong brightness.
    But good LED for the market must have those all features. To be good at light nature to go straight means that it is good at visibility range. In case of fluorescent lamp, it is possible that the visibility range can reach to 2 meter away but in case of LED, it is hard to do that. Oval type can reach 2 meter as the light goes straight well but we can see only one mere spot when it reaches to the target as the brightness is weak.
    Therefore, to fulfill strong brightness, SMD type must be used, and to apply lens like one that oval type has to be SMD type is key point. When lens is being applied to SMD type, it does not go to SMD module directly. It needs a pipe which is same shape with conventional fluorescent lamp as a lens. It is quietly complicated to make the pipe because the pipe? molding can not be adjusted once it is made.

    Comply with the operating system of Fluorescent lamp
    Lens acts like magnifying glass and they are used for landscape lighting LED over 1 Watt. It affects a lot to landscape lighting LED? brightness and light? straightforwardness up to more than 10 times of brightness by depending on lens?existence or nonexistence.
    Pipe for LED fluorescent lamp can be made of either transparent or translucent. If the pipe is transparent, light dots through transparent pipe can be shown. In case of translucent pipe, brightness can be strong enough with adding powder and diffusive medium on its surface. Also it is hard to recognize whether it is LED lamp or fluorescent lamp as the inside of pipe can not be seen through.
    Usually, fluorescent lamp gets 220 voltage input and transforms it to 135 voltages through stabilizer and emits light. Comparing to fluorescent lamp, LED fluorescent lamp receives 220 voltage input to PCB which is installed behind to transform 220 voltage to 12 voltage and emits light. PCB works same function as a stabilizer.
    Normally, fluorescent lamp system has a stabilizer so it has to be adjusted for LED fluorescent lamp replacement.
