The ambient light temperatures corresponding to the highest lumen output of the TL5 and TLD lamps are 35 ° C and 25 ° C, respectively. It can be seen that the highest light output of the TL5 lamp corresponds to an ambient temperature of 35 °C. TL5 lamps for offices, shops and public buildings are generally installed in luminaires. Since the temperature in the luminaire is generally higher than the temperature of the illuminated area, the operating temperature of the enclosed TL5 lamp is close to its optimum temperature. . Comparison of the lumen output of the bare lamp TLD and TL5 ambient temperature The high lamp energy density indicates a high loading of the phosphor coating. Since the rare earth trichromatic phosphor can withstand higher loads, the high light effect small diameter fluorescent lamp TL5 is available.
TL5 also coated a protective film on the glass tube like TLD to prevent mercury from reacting with the glass, and the 10,000-hour lumen maintenance rate was 95%. It is the lumen maintenance performance of the TL5 lamp. The use of protective film technology can prevent mercury loss. The amount of mercury used in TL5 is 3mg, which is reduced by 80%, and the amount of glass is also small, which is conducive to a clean and hygienic environment. The rectangular ceiling system of the office in the lumen maintenance rate of the TL5 fluorescent lamp. In general, the TL5 lamp is a 1.2m long, 10000 hour lumen maintenance rate of 95%, an average life of 16000 hours, and a light pipe diameter of 2900 lm. Fluorescent light. Based on the information, you can understand whether the luminous flux meets the requirements. A standard rectangular ceiling system for a 10.8m x 7.2m office. The position of the luminaire is fixed by the ceiling system, the illumination is required to be uniform, the luminaire arrangement is symmetrical and beautiful, and it complies with the standard of use of the video terminal. It is a comparison of the three options. Scheme 1 is a TLD lamp with an inductor ballast, Scheme 2 is a TLD lamp with an electronic ballast, and Scheme 3 is a TL5 lamp with an electronic ballast. The illumination from the visible TL5 lamp 2900lm satisfies the ignition point of 14000 hours (recommended replacement cycle), and the illumination is 500lx.
BHRS is a new ignition time for the new TL5 fluorescent lamp with electronic ballast. The lamp diameter is also small, which requires a smaller lamp head instead of the existing TLD or TL lamp. In addition, it also needs to be equipped with electronic ballasts, so TL5 lamps can not be directly replaced with TLD or TL fluorescent lamps. Matching TL5 lamps with different sizes of lamps can avoid unconventional use. The above situation also facilitates the optimization of the length of the lamp. Practice has shown that the length of TL or TLD is not always suitable for ceiling lamps. 1.2m long tubes are used in standard ceiling fixtures, but the actual length of the TL lamps is 1213mm, which requires the fixtures to be suitable for extended light boxes. To overcome the above shortcomings, the TL528W has a lamp length of 1149mm, which can be easily used in standard 1200mm surface mount suspension luminaires. Various specifications of TL5 lamps meet the above requirements and are their parameters. It is foreseeable that there will be many new occasions in the future that require the use of TL5 lamps. The low operating costs of electronic ballasts make them more widely available. Another advantage is that it maintains the lamp current constant regardless of the grid voltage, thus extending the life of the lamp. Of course, this means that you can change the lamp less during operation. For each type of lamp, there must be a corresponding electronic ballast. To achieve the highest system efficiency, electronic ballasts must be designed with the best combination of tubes.
The advantages of TL5 lamps and optical design TLD and TL5 lamps compared to TL5 lamps provide a broad prospect for luminaires and optical design, and the market requirements for miniaturization of lamps can be met. Indicates that the size of the optical system is greatly reduced. The size of the luminaire is directly related to the diameter of the tube. The diameter of the TL5 is 40% smaller than the TLD. The optical system can be reduced by 40% while maintaining the same performance. This is for hanging and surface mounted luminaires. Great advantage. Of course, small size is also an important advantage for ceiling lamps. The TL5 has a shorter lamp and can be easily installed in standard ceiling fixtures. The reduced height of the ceiling luminaire indicates that it requires less installation space. The reduction in the space of the ceiling and ceiling luminaires leads to a reduction in the space of the building. Where the size of the luminaire is not critical, the luminaire designer can use a larger optical system to improve its light efficiency.
