To using different metal halide lamp "inductance ballast and trigger circuit of the decay curves on the one hand improve discharge tube structure, the abolition of the starting electrode, as shown in Figure 10B and improved chemical formula and manufacturing process, to improve the starting performance of the lamp, thus comprehensively improved the performance of the lamp. On the other hand, to improve the working circuit of the ballast, trigger to start the lamp work, so as to reduce the open circuit voltage of the ballast, which reduces the peak voltage and peak current. The working temperature of the ballast is correspondingly reduced, and increases the life span of the ballast, reduce maintenance costs in Table 4 for two types of Sc-Na metal halide lamp and ballast main performance parameters of the comparison of pulsed metal halide lamp starting Sc-Na can the better performance of the CWI and regulated.
In our daily life, we often come into contact with the concept of incandescent lamp, fluorescent lamp, energy saving lamp and LED lamp. But do you really understand the difference between these lights? Do you know how to work? Do you know their strengths and weaknesses? Let us spread the knowledge of these lamps.
A): energy saving: white LED energy consumption is only 1/10 of incandescent lamp, energy saving lamp 1/4;
B). Fast response: LED fast response, completely eliminates the defects of the traditional high pressure sodium lamp and Hui Long process. A white LED lamps into the home is agile arrival.
C). Environmental protection, do not contain mercury harmful substances to the environment, not the formation of damage to the environment. Led lamp assembly parts can be very simple disassembly, do not have to recover the manufacturers can go through other people's recovery. Led does not contain infrared, ultraviolet, so do not recruit insects.
D). Color: than traditional lamps and lanterns that light can be more near white. In this light, the color of an object can be more near the nature.
E). Solid state packaging, to the type of cold light source. So he is very convenient for transportation and equipment, can be the device in any micro and off the device, not afraid of a hit, the first thought is heat.
Summary: it is clear that only the LED lamps with the continuous improvement of the LED technology. Energy-saving lamps and incandescent lamps will be replaced by LED lamps. At present, the country is paying more and more attention to energy saving and environmental protection, has been vigorously promoting the use of LED lamps.
High-pole lamp: generally refers to a new type of lighting device more than 15 meters of steel column type lamp and high power combined lamp bracket. It is composed of a lamp holder, lamp, electric rod and basic parts. Decorative lamp can according to user requirements, the surrounding environment, lighting need specific and definite; the lamps and lanterns more by floodlights and cast light on the composition, and the light source using NG400 high-pressure sodium lamp, lighting radius of up to 60 meters. Rod body generally cylindrical type single body structure, steel plate rolled, height of 25 - 40 meters to 25 meters of steel column type lamp and high power combined lamp frame a new lighting device. It is composed of a ceramic lamp holder, lamp, electric rod and basic parts.
Home lights as an important part of the family, good or not related to the quality of home life. But generally speaking, a lot of people do not care about the maintenance of the lamp, even if the lamp is broken, it will be considered a problem of quality. In fact, the lamp in the use or installation of a certain law, if in accordance with the law, the use of lamps and lanterns are very long life is the premise of the correct installation.
