Discussion on the application of high-power energy-saving lamps in actual lighting

High-power energy-saving lamps extend the lighting application technology of low-power energy-saving lamps from indoor small-scale lighting applications to a wide range of indoor and outdoor lighting applications. This is a breakthrough and an innovation in application technology.

High-power, ultra-high-power energy-saving lamps are available in two production and two different applications.

One is a self-ballasted integrated high-power energy-saving lamp that integrates an electronic ballast and a lamp tube in one body; the other is to separate the lamp tube and the electronic ballast into separate independent high-power lamps. Energy saving lamp. Split-type high-power energy-saving lamps for high-quality products, the connection distance between the lamp body and the electronic ballast can reach 20M-30M.

The split type energy-saving lamp installs the lamp and the ballast, and connects the lamp and the electronic ballast with wires in the middle, and then uses the two installation methods for lighting. The advantage is that the ballast can be interchanged with the lamp. If the lamp is broken, the lamp can be replaced, and if the ballast is broken, the ballast can be replaced. The split lamp can be installed in a sealed luminaire without concern for the hazard to the lamp due to the high temperature rise. The above two products are divided into E27 and E40. Self-ballasted integrated high-power energy-saving lamps can be installed directly on the corresponding lamp head for lighting. Since the integrated energy-saving lamp has certain limits on the ambient temperature and the use temperature, the use of the integrated energy-saving lamp is limited in the sealed lamp which is greatly affected by the overall temperature rise. It is better for use in open luminaires. Otherwise it will affect the service life of the integrated high-power energy-saving lamps. The above is an introduction to two different installations of high-power energy-saving lamps and different forms of use. The following describes the application of high-power energy-saving lamps in actual lighting from the performance characteristics of high-power energy-saving lamps.

There are two types of high-power energy-saving lamps from the installation and use form: active filtering and passive filtering in the APFC and PPFC filtering forms. And there are products with different power factor and high power factor and low power factor.

High-power energy-saving lamps with low power factor cannot be used in applications where electromagnetic interference and electromagnetic compatibility are highly demanded. Such as: automatic control, radar station, telecommunications, navigation, communication, computer room, instrument room and other occasions. High-power electronic products with low power factor cannot be installed in large quantities in the same area at the same time. A large number of large-area energy-saving lamp products using low power factor, due to the ultra-standard harmonic content (the third harmonic is more than 80%), will directly cause the phase shift of the power supply, which will result in zero-line overcurrent. Causes a fire accident of wires and equipment. It is generally not desirable to produce products with low power factor, and there are certain standards for this product at home and abroad. High-power factor high-power energy-saving lamps usually have a high power factor, generally above 0.95, and the third-harmonic content is less than 37% below the standard. If the technical standard of high power factor exceeds 0.99, the total current harmonic content can be controlled below 8%, and the third harmonic content is less than 5%. If the EMI and EMC circuit suppression circuit design of the filter circuit front end is used again, the electromagnetic compatibility can meet the requirements of the International Electrotechnical Commission for the electromagnetic compatibility below 45dB. It can be safely used in applications where electromagnetic interference, conducted interference, and radio frequency interference are required. The third harmonic is better controlled and can be used in a large area. Does not cause phase shifting of the power supply and zero line overcurrent. The high-power factor electronic product design has protection measures for over-voltage, over-temperature, over-temperature protection and other safety performance settings. The safety factor in large-area use and the reliability of the product are high, and no accidents occur. Fire hazard. In the new standards at home and abroad, the promotion of high-power factor electronic products above 0.9 is advocated, and it is also the future design effort in the electric light source industry.

The innovation of high-power energy-saving lamps reflects the advantages that many other electric light sources do not have in actual lighting:

First, the color rendering index is high, up to 79-85. It is much better than self-ballasted mercury lamps with a color rendering index of only about 0.5. It can be used in important occasions such as photography, TV broadcast, printing and dyeing factory, weaving factory, and laboratory where high color reproduction is required.

Second, the high efficiency: in the actual application circuit of 45KHZ operating frequency, the light efficiency can reach the technical level of 58LM-68LM/W. In the same environment, the light efficiency of 85W high-power energy-saving lamps can reach 5800-6300LM, which is equivalent to the brightness and illumination of a 400W incandescent or 350W self-ballasted mercury lamp. The energy saving effect is up to 80% or more. It is a new product that replaces the elimination of self-ballasted mercury lamps and incandescent lamps. (The color rendering is lower than the incandescent lamp).

Third, the high power factor is above 0.95-0.99, and the service life of the lamp can reach 5000 hours. The lamp life of high-quality products can reach more than 8000 hours, which is five times that of incandescent lamps. The overall service life of the split type high-power energy-saving lamps can reach more than 12,000 hours, and the economic benefits are very obvious.

Fourth, special color temperature manufacturing technology: color temperature manufacturing technology of high-power festival lights, from 300K dark red to 20000K blue high color temperature. This is a major feature of high-power energy-saving lamps. The use of special color temperature is very peculiar. The color temperature of 17000K is very shocking for the seed culture of special plant bioengineering. She can achieve the control and improvement of plant growth through special color temperature illumination. Can be used for directional farming in plant organisms.

V. Special explosion-proof use environment: High-power split-type energy-saving lamps can be applied to refineries, chemical plants, military factories, explosive factories, flour mills, gas supply plants, gas supply stations, gas stations, etc. Warehouse, oil, flammable and explosive occasions. It is possible to directly replace mercury and incandescent lamps without changing the original sealed explosion-proof lamps.

6. Indoor lighting: It can break the use limitation of low-power energy-saving lamps with insufficient illumination. It can be used in buildings, halls, halls, halls, waiting rooms and waiting rooms with high altitude, large space, high contrast and brightness. Conference halls, photography studios, stage, factories and mines, enterprises, big shopping malls, theaters, dance halls, restaurants, gymnasium schools, etc. Improved environmental lighting usage. Seven, the application of outdoor lighting: can be used directly in the use of the height of 6 meters -10 meters. Such as: stations, docks, plazas, ports, airport residential quarters, stadiums, stadiums, street lights and bright lighting projects in the city.
