Philips Lighting is the world's largest lighting company, one of the three giants of traditional lighting, mainly producing carbon filament bulbs in the early days, and now its business covers the entire lighting industry chain from light sources to lamps, from traditional lighting, LED lighting to the emerging field of smart lighting.
 
Philips has made many achievements in the traditional lighting era, and its trichromatic phosphors and energy-saving lamps have rewritten the commercialization process of fluorescent lamps. Ultraviolet lamps are disinfection and sterilization equipment, and are not used for lighting, but their principle is basically the same as that of fluorescent lamps, which are produced by ionizing low-pressure mercury vapor. With this in mind, it's easy to see how easily Philips can penetrate from lighting to sterilization.
 
Philips is not only well versed in the manufacturing process of light sources, but also in the leading position in ultraviolet sterilization technology, and is the first company in the industry to integrate resources in the field of ultraviolet disinfection. Philips is the only manufacturer in the world that has developed a complete set of UV light sources, drivers and modules through extensive research on water quality, water flow velocity and water temperature, as well as biological experiments and microbial performance tests.
 
Philips' industry-leading technology ensures the quality of its products. The high-quality coating used on the inner wall of the UV lamp can ensure that the UV output is constant, and the output rate will not be less than 85% of the initial output during the entire service life, which is much higher than the national standard "not less than 65%". In addition, Philips UV lamps have the lowest early failure rate in their class, with 90% of the light sources operating beyond their calibrated life and the required output and quality.
 
The effective life of Philips ultraviolet lamps is more than 9000 hours, close to twice the national standard, and can be used for 24 years according to the calculation of 1 hour of use per day.
 
In fact, Philips only offers original light sources, and the lamp holders and brackets are manufactured by qualified manufacturers selected by the distributor. Lampholders and brackets only play a protective role, the technical content is relatively low, and China, as a big manufacturing country, can find many reliable manufacturers.
 
Depending on the number of lamp fittings, Philips UV lamps are available in single-ended and double-ended types, with single-ended UV lamps and lampholders providing mobility and can be placed on floors, tabletops and chairs in various rooms as needed, and double-ended lamps can be assembled with brackets to be hung from the ceiling or screwed to the wall. The price of Philips' single-ended lampholder is 200-400 yuan, and the price of double-ended bracket lamps is less than 200 yuan due to the relatively small power.
 
Philips ultraviolet lampholder series uses TUV PL-L single-ended light source, T stands for Tube (lamp), UV stands for ultraviolet ray, PL is the English abbreviation of Poland, this series of lamps are manufactured by Polish factories, and L is Large (large) meaning, refers to the large size of the lamp, and TUV PL-S small size lamp, which is introduced in Philips's "2015 ultraviolet product catalog", but is not currently sold on the market. TUV PL-L lamp has 18W/36W/55W three power options, the general ultraviolet lamp and disinfection area is "1W corresponds to 1 square meter" relationship, such as the bathroom or bedroom these smaller space, the choice of 18W is enough, like the hall needs 36W/55W to ensure a better disinfection effect, although the small power of ultraviolet lamps can also be placed in different positions to achieve all-round disinfection of large rooms, but it is more troublesome.
 
Philips bracket lamps can also be divided into two types, one is a T5 tube with a diameter of 16 mm and the other is a T8 tube with a diameter of 25 mm. The power of T5 lamps is on the small side, and the optional power range is 4W-15W, while the T8 lamps are all high-power, covering 4 kinds of power of 30W-75W, of which 55W and 75W belong to the high-output version, and the model suffix is marked with "HO", although the size is the same as other lamps, but the output power has increased a lot.
