In the drive to develop better and more effective interior illumination, most of the progress has been made since the 1930s. Commercial establishments and employers wanted to be able to work longer hours, particularly during the war years when higher production was demanded. The development of commercial hanging fluorescent light fixtures were not only less costly to operate, but they had other advantages as well. They are used in many locations today where they are both utilitarian and attractive.
As with any other lighting source, the main reason for using fluorescent bulbs is to provide illumination. With large open spaces, the source of the illumination is often this type of lighting fixture. The chains or cords are utilized to bring the fixture closer to the worker or customer's level. Illumination is the best way to make products look attractive and to improve the workspace of employees during night shifts.
Use of this type of lighting offers a number of advantages. For instance, they are the most energy efficient type when utilized in the interior of a space. They can also be utilized outdoors. The tubes are not expensive to produce. The ballast components are more expensive. Both the bulbs and the ballast are long-lasting. Colors are available in cool to warm white shades. The illumination is diffused, thus eliminating shadows and harsh glare.
There are three major types of fluorescents. Cold cathodes and hot cathodes are similar. Electroluminescent bulbs are different in many ways, but all three types use phosphors excited by electrons, in order to create illumination.
Of the three main types of fluorescent lights, the hot cathode style is most commonly found. Usually, it consists of a long glass tube containing an inert gas (often argon). The gas is under low pressure. There is an electrode on either side of the tube, made of tungsten. The ballast controls and regulates the AC power input to the electrode. The standard size of the tubes is four feet. The illumination offered is 40 watts. In the past, ballast tended to be magnetic. Today they are usually electronic. Electronic ballast is less costly to produce and requires less material.
The cold cathode lamp is also available. The main difference between it and the hot cathode lamp is the coating on the interior of the lamp. Originally this device was not intended as a light source. It also contains gas. The electrodes are attached to either end of the bulb.
The third type of lighting is EL (electroluminescent or high field electroluminescent lamps). In this style of fixture, electrical energy is converted into light and no heat is required in the process. Electrical current is transferred directly through phosphor in order to achieve the desired result.
The lamps are made more attractive by adding decorative covers. The covers help to further diffuse the light and remove any glare or strong shadows. Although a long straight bulb is the most common style of lamp, it is being joined by other shapes and lengths in order to meet specific needs in the commercial area. For lower energy usage and functional lighting, the fluorescent lamps represent the best option.
