Description
LIzJER TPE, ALUMINUM EXTRUDED FLUORESCENT LnMP This invention relates to linear type, aluminum extruded fluorescent lamp.
Since the invention of electric lamp created by
Thomas Edison, the living style of the people has been drastically changed. In ancient times, people were abiding by the time table confined by the Sun "to start work at daybreag and to retire at sunset". Rs soon as electric lamp is available, people become free from the restraint of natural environment and time, to widely apply electric lamp at night to fully make use the time 24 hours a day.
Following fast development in technology, fire power and water power generating techniques provide the people with convenient electricity. Therefore, people keep to devote themselves to develop innovative electric home appliances and electric machinery. Now, the great success in nuclear power provides the people with more cheaper electric power.
However, while seeking for better enjoyment of life, people are gradually losing their vigilance to protect "the window of the soul" -- the eyes. If the power of vision is obstructed, a people who lives in the modern time will become a man like living in the ancient times before the invention of electric lamp. It is very regretful that in our living environment there are bad quality lighting devices to hurt our power of vision at all times.
Following the fast development in business as well as in industries, illuminator has become a requisite equipment everywhere in factories, offices or our own homes.
Facing the variety of illuminating attachments, it is quite important to select a quality illuminator to provide proper intensity of illumination so as to protect "the window of our soul".
While selecting an illuminator, people may concern about the appearance rather then the quality of the intensity of illumination. Actually, this is a wrong way. It is very harmful to our eyes to work, read, or write under excessive or poor intensity of illumination for a long period of time.
Fluorescent lamp is a power-saving illuminator, more acceptable to the people, which provides good intensity of illumination similar to the sun light. Therefore, fluorescent lamp is commonly used in big place for long term illumination. There are two kinds of fluorescent lamp tubes available in the market, one is linear type, the other is ring-shaped type. The ring-shaped type is not as flexible as the linear type while in application, since the ring-shaped type is limited by its intensity of illumination and its applicable environment. The linear type fluorescent lamps that are commonly used are designed to provide five specifications: 40W, 30W, 20W, 15W, and lOW, of which the length is about 4ft., 3ft., 2ft., 1.5fit., and loft.
respectively, and the design and assembly can be made in accordance with the location and illumination intensity required.
For producing linear type fluorescent lamps, it needs to provide respective moid for each si=e. For abovesaid flve speciflcations, it will require five different sets of molds for the production. This is not an economic way.
For variety production, it requires to frequently change the mold, therefore, the production may be stopped or a bottleneck may be resulted in the production.
Further, the illuminating attachments that are commonly used may cause dazzling problem. This problem may become more serious in the illumination-intensive area. The dazzling problem may arise if to watch the fluorescent lamp directly or to let the eyes be illuminated by unparallel light rays, such problem may affect the working efficiency or emotion, or even more seriously endanger the working security to blear the eyes. Currently, big scale illuminating equipment manufacturers are competing with one another to invest money in creating dazzle illuminators. Now, there are some dazzle-proof illuminators available in the market.
However, regular dazzle-proof illuminators are very expensive and inconvenient to install, and the heavy size of these dazzle-proof illuminators may force the ceiling to protrude downward. The tube of regular linear type fluorescent lamp is in a tubular shape, which provides illumination by means of radiation. The fluorescent lamp that is commonly used provides illumination directly by means of the lower half portion of the tube, the light rays radiated from the upper half portion of the tube are normally reflected by means of a lamp shade. Because regular fluorescent lamps are commonly used in open spaces where the floating dusts may easy to ac-umulate on the upper half portion of the tubes to drastIcally reduce the diaphaneity and the light of reflect.
Furthermore, few people have tne custom to periodicaliy clean the surface of the fluorescent lamp tube. Therefore, the illuminating quality is deteriorated day after day. Said problem becomes more serious in factories where do not have air conditioner and dust collection system, schools, and shops or residences in the street.
Further, the fluorescent lamp that is commonly used has to be attached with a stabilizer and a starter.
Therefore, the whole assembly is not a compact design, which can not provide high performance in application due to heavy structure.
In view of the inconveniences and problems existed in the illuminators that are commonly used, a dazzle-proof, compact, linear type and aluminum extruded fluorescent lamp is thus created to provide high intensity of illumination, of which the reflecting plate is adjustable within the range of 0-900.
