2 lighting power features

Lighting has become an indispensable measure in all social activities such as human life, work, production and entertainment. With the rapid development of society and technology, people's requirements for lighting are not limited to using it to see objects. Rise to a height that is bright, soft, environmentally friendly and gives a visual beauty. The expansion of the scale of industrial production requires that the matching lighting capacity will inevitably increase. In recent years, urban night lighting has become the mainstream of night power supply. Bright lighting has made most cities a city that never sleeps. These have brought huge economic benefits and conveniences and enjoyment to people's life, work, production and entertainment.

However, there are still many problems to be solved in the lighting of many units at present: a large amount of power loss causes high electricity costs; frequent replacement of lamps makes the unit have to pay more for the lamps and their accessories; Increased human resources caused by maintenance; light pollution caused by intense lighting; heat radiation generated by large-area lighting fixtures, etc. In order to solve these negative effects, the National Energy Office has mandated that lighting projects must meet the requirements of green, energy saving and environmental protection.

In response to the above problems, the power unit has taken some measures to improve and alleviate these contradictions.

3 energy-saving lighting power supply works

3.1 The main way of lighting energy saving

One way to save energy in lighting is to use an efficient energy-saving light source, that is, to use a bulb or a lamp with high luminous efficiency; and second, to install an energy-saving control device on the existing lighting system.

From a practical point of view, the first option is applicable to the newly designed lighting circuit. For the existing lighting system, because of the need to replace all the lamps, the initial investment and manpower are relatively large. In the lighting place where the lamps cannot be updated in batches, the one-time investment is too large, which makes many units discouraged. High-efficiency energy-saving light sources (lamps, bulbs) are 5 to 10 times the price of traditional light sources. If the quality of the energy-saving lamps purchased is problematic or the quality of the power supply is not good, the life-saving lamps can be used for a short period of time, which may result in the use. The unit has an abnormal phenomenon of “energy saving and not saving money”.

For the energy-saving retrofit of existing lighting systems, it is more economical and practical to install energy-saving equipment. At present, there are many lighting energy-saving equipments sold in China, among which lighting control and control devices account for the largest proportion. From the working principle, it is roughly divided into three categories:

(1) Thyristor chopper type lighting energy-saving device

By using the thyristor chopping principle, by controlling the conduction angle of the thyristor (thyristor), the sinusoidal voltage input to the grid is removed, thereby reducing the output voltage value and achieving the purpose of voltage regulation and power saving.
