subject: Reasonable Purchase Energy-saving Lamps For The Green Light To Contribute To - Red Marble Texture [print this page] According to China's "China Green Lights Project", lighting, energy saving has become an important aspect of energy saving, energy-saving illumination is guaranteed under the premise of promoting energy efficient lighting equipment, improve energy efficiency, reduce energy consumption.
With the deepening of reform and opening up, the rapid economic development and the people raising the level of lighting electricity consumption in China has 7% of total consumption -8%. According to China's "China's green lighting project," saving lighting has become an important aspect of energy conservation, energy-saving illumination is guaranteed under the premise of promoting energy-efficient lighting equipment, improve energy efficiency, reduce energy consumption.
1. Scientific use electric light
Scientific use electric light the most important issue is energy saving lighting. At present, the domestic production of electric light source of luminous efficiency, lifetime, color rendering properties are constantly improving, emerging energy-saving electric light source, light-emitting principle of electric light source can be divided into two categories according to. One is thermal radiation power source, such as incandescent, halogen, etc.. The other is gas-discharge light sources, such as mercury lamp, sodium lamp, xenon lamp, metal halide lights. The luminous efficiency of various power sources are quite different. Gas discharge light source than the thermal radiation power is much higher. Under normal circumstances, may be gradually replaced with gas-discharge light source radiation light source, and possible use of light-efficient gas-discharge light sources.
High pressure sodium lighting efficiency is 8 to 10 times incandescent, long life characteristics of stability, and luminous maintenance rate, suitable for less demanding in the color of roads, squares, docks and large indoor venues such as plant and warehouse lighting .
Metal halide lamp with high luminous efficiency, good color, large power characteristics, suitable for theater, assembly plant and other large area lighting field 3. 70% saving compared with incandescent lamps for the office, quarters and roof height of less than 5 meters of workshop and other indoor lighting. Compact fluorescent lamps with high luminous efficiency than 5% of normal, small fluorescent lamps than the average 10% saving fluorescent lamps, so compact and small fluorescent lamps is the "Ninth Five-Year" period, "China Green Lights Project" program launched energy efficient electric light sources.
In the opening and closing frequently, small size, require low lighting situations, can be used incandescent lamps. Double helix than the single helical filament-type incandescent filament type incandescent lamp luminous flux increase of 10%. Selected according to priority.
2. Rational choice lighting
The main function of lighting is a reasonable distribution of light radiation flux, the environment and operations equipped to meet the light requirements, and does not produce blinding light curtains phenomena and serious reflection. Select lamps, in addition to considering the environment and limit glare light distribution requirements, should also consider the efficiency of lighting, choose lamps with high luminous efficiency.
In all kinds of lamps, the fluorescent lamp is mainly used for indoor lighting, mercury and sodium lamps for outdoor lighting, and it can be mixed together, the two installed lighting. This high luminous efficiency, low power consumption, light color fidelity, coordination, visual comfort.
In addition, the lighting design to be used with reasonable light. Such as incandescent lamps in the curvature of the deal is reasonable, under the same illumination could be saving 20%, fluorescent lamp light weight design stagger some, can increase the optical efficiency of 80%.
