Stroboscopic refers to electric light flux fluctuation depth. Flux fluctuation depth increases, the more serious the strobe. Electric light flux fluctuations in the depth of the size, and the electric light source technology and quality have direct relationship between electric light flux fluctuations in depth size, usually as a percentage. At present, has been widely used in the electric light source, such as magnetic ballast driven T8 (26mm) straight tube fluorescent lamp, high pressure mercury lamp, high pressure sodium lamp, metal halide lamp flux fluctuations in the depth of up to 55% - 65%. And market on the part of the technology of poor quality energy-saving lamps, there are still as high as 20% - 30% of the depth of stroboscopic stroboscopic effect refers to the electric light source produced by the fluctuation of luminous flux and harmful effects, which produce stroboscopic damage effect. Electric light stroboscopic more serious and stroboscopic effect the more serious harm visual identification and evaluation of energy saving lamp stroboscopic and stroboscopic effect, usually by flicker detection dedicated gyro identification and evaluation of energy saving lamp stroboscopic and stroboscopic effect, is using solar light as the standard. The sun light flux is smooth and stable, no stroboscopic stroboscopic effect and harm. Flux smoothing energy-saving lamp stability, more close to the sun, the stroboscopic depth energy-saving lamp is smaller, less harm stroboscopic effect...

Generally speaking,the led plant lights are red and blue light, basically are red blue less, because the photosynthesis of plants is most sensitive to red and blue to red absorption, absorb little blue, red light is generally promote flower leaf growth, blue light promoted the differentiation, the LED lamp is by controlling the ratio of the number of red and blue beads to accurately determine the proportion of red and blue light, at present market led plants fill light blue and red ratios ranging from 3:1 to 8:1 can also be choose custom. According to the relevant academic papers I read, red blue light is more appropriate than the 5:1~10:1. I chose the red and blue of 5:1, the seller said that they are specialized in the export business of the United States. I also checked, do have led lights like the plant domestic sellers in foreign ebay. In addition, I also investigate the situation in Japan, Japan has finished led plants fill light special....

Low pressure sodium lamp is the best source of solar street lighting system: low pressure sodium lamp emission wavelength is monochromatic light and 589.6nm 589.0nm. The two yellow spectral line positions near the human eye is most sensitive wavelength is 555.0nm green spectral lines, not only has high luminous efficiency, and in the eyes of the world does not have a color, so see high resolution, good contrast for in road, overpass, tunnel and intersections high visibility and color requirements. Low pressure sodium lamp also has no glare. The luminescence efficiency is 200lm/W low pressure sodium lamp, electric light source is the highest light efficiency of a light source, the life is long....

HID street lights only carried out in a small range of dimming, LED street lamp can be completed within the range from the 0%~100% dimming control, can be based on the environment and traffic conditions sensitive light output, in order to ensure the lighting needs of the situation to reduce unnecessary energy consumption. Thus, about for a total lighting electricity consumption is about 15% to 20% of the road lighting, large-scale implementation of LED street lamp, on carbon reduction and energy conservation has important significance of street life directly affects the road lighting maintenance costs. The high-pressure sodium lamp life is usually about 2 million hours, the road lighting with the use of high pressure sodium lamp life expectancy only about 5000 hours, and high power LED life often 5-7 million hours of high-pressure sodium lamp and led uniform his definition is not the same. High pressure sodium lamp uniform life definition for "will a group of subjects source sample points to 50% damage to the number of times", and led uniform life is refers to "the number of tested sample to decay to 70% of the 50% of the number of times" if according to his definition of high pressure sodium lamp to measure led, life expectancy is 50000 hours led up to 1 00000 hours; if according to the definition of life led to measure high voltage sodium lamp reached for 2 million hours of high pressure sodium lamp only about 1 million hours of course, led long life is not the LED street lamp life. LED lamp life is by LED light source life and driving circuit of life with resolution and led and its driving circuit of life lies in lamp heat dissipation ability, circuit topology structure and electronic equipment to select a variety of elements. From the current level of skill, LED lamp life can go beyond the high-pressure sodium street lamp....

Generally speaking,Selection ceiling lamps depends on the light ballast and the circular lamp, ballasts have magnetic ballast and electronic ballast, compared with the magnetic ballast, electronic ballast can improve the effect of light on the light and the system, instantaneous start, extended lamp life. At the same time, it is small, no noise, small size, light weight, power consumption is only 1/3 to 1/4, the inductance ballast, so consumers have to choose the electronic ballast. Ceiling lamps of the circular lamp with halogen powder and trichromatic fluorescent powder and powder lamp trichromatic color color, light and slow light degradation; powder halogen lamp display color and luminosity, low light decay quickly....

The plants grow light source: high pressure sodium lamp, metal halide lamp, ceramic metal halide lamp, microwave sulfur lamp, plasma lamp, fluorescent lamp, no electrode lamp and led. Is the most commonly used sodium lamp, metal halide lamp and LED. Other relatively small minority, price or very expensive high pressure sodium lamp can be divided into ordinary sodium lamp, sodium lamp with high photosynthetic efficiency, plants with sodium lamp, used a 250W, 400W, 600W, 1000W....

Before buying, first of all we should measure about the installation position of the decoration indoor height, if the height of less than 2.6 meters is not recommended optional pendant lamp products. Because chandeliers are usually need to drop more than 40 cm only better effect, and in indoor low height install droplight not only failed to good decorative effect, but also make indoor space is low, depressed, it is very worth the candle in the indoor highly suitable for optional chandeliers, lamps and lanterns of choose and buy also need to pay attention to the chandelier design, shape, color, style and the style of decoration in harmony, which is to select and purchase chandelier must pay attention to the problem....

High pressure sodium lamp discharge material vapor pressure is very high, namely high atomic density of sodium, sodium atoms and electron collision between the number of frequent, the resonance radiation broadening of spectral lines and other visible spectrum of radiation, so the high-pressure sodium lamp light color is better than that of low pressure sodium lamp. High pressure sodium lamp is a kind of high intensity gas discharge lamp. Due to the negative resistance characteristics of gas discharge lamps, if the lighting alone received the power grid, the working state is unstable, with the discharge process continues, it will lead to circuit current rises indefinitely, until the last light or circuit parts and components is flow burning high pressure sodium lamp and other gas discharge bulb, work is arc discharge state, V-I characteristic curve to the negative slope, i.e. lighting current rise, and the voltage applied to a bulb dropped....
