Daily update of energy-saving lamps and incurable diseases (on)

Question 1: Why does my family's electronic energy-saving lamps flash after turning off the lights? Is there any way to solve them? The problem is added: the new lamp is also flashed, and the lamp itself is newly bought. The number of lamps is still changed. So, but if you put on the light bulb, it won’t flash? Answer: This is caused by the switch of your light that is not broken by the fire wire. You can change it and break another wire. If it is not convenient, just connect the two wires upside down on the meter or knife switch or air switch. Problem 2: One lamp, four 11-watt energy-saving lamps, the same power consumption as the Baizhi lamp? Answer: Two are similar. Because 11W energy-saving lamps consume 11W, and 40W fluorescent lamps are only the power of fluorescent tubes, but there are also ballasts on fluorescent tubes. If it is a past ballast, its power consumption is about 8W, now the electronic town The flow device will save some power, but it will also have at least 3~4W. Calculate the power of four 11W energy-saving lamps is 44W, and the power of 40W fluorescent lamps is between 43~48W. Comprehensive comparison, the two consume almost the same power, but the energy-saving lamps will be brighter. The disadvantage is that the color temperature is too high, and it is a bit cold to watch the gas. Three: The energy-saving lamp is still slightly flashing after turning off the light, will it damage the life of the lamp? Answer: This is only the natural luminescence phenomenon of the fluorescent material in the energy-saving lamp after being excited by high energy. After the lamp is turned off, the energy supplement stops the flash and will stop slowly without damaging the lamp. Question 4: The evaluation method for purchasing the energy-saving lamp is what? First, several physical concepts that need to be scientifically understood 1. Energy-saving lighting effects: It is a physical quantity that characterizes energy-saving lamps and converts electrical energy into high-efficiency light energy. The unit is: lumens / watt (Lm / W). The higher the light efficiency, the more energy-saving lamps are saved. The actual luminous efficacy of energy-saving lamps depends on the technical quality of fluorescent tubes and electronic ballasts, and the reasonable degree of matching between the two. 2, energy-saving lamps effective visual light effect: energy-saving lamps produce light energy, including visible light and invisible light. The effective visual light effect is a physical quantity that represents the amount of visible light in the light energy generated by the energy-saving lamp, which can be perceived by the human eye. The effective visual light effect is a purely digital physical quantity, which indicates the effectiveness of the light source. The mathematical expression is: effective visual light effect = the amount of light generated by the electric light source. The light energy perceived by the human eye can effectively reduce the visual effect of the energy-saving lamp, and is directly related to the technical quality of the fluorescent tube and the electronic ballast itself. The lamp produced by the rare earth trichromatic high-efficiency phosphor is matched with the AC-DC-AC conversion frequency, and the energy-saving lamp of the high frequency electronic ballast higher than 40Khz. The effective visual light effect is high, and the actual brightness and power saving rate of the energy saving lamp are high. 3, energy-saving lamp brightness: refers to the brightness of the eyes when people look at the energy-saving lamps. The brightness is determined by the color temperature of the energy-saving lamp and the light energy of the energy-saving lamp. The light energy of the energy-saving lamp is a decisive factor. The more light energy the energy-saving lamp has, the higher the brightness. In particular, the brightness of the energy saving lamp. People's visual sense is sometimes greatly affected by color temperature. In an energy-saving lamp with the same light energy, an energy-saving lamp with a high color temperature produces a high-visual visual sense. This kind of "high-brightness" energy-saving lamps, the illumination is not higher than other energy-saving lamps, and the light effect is not higher than other energy-saving lamps, just a glareous "false light". Please pay special attention when purchasing energy-saving lamps. 4. Energy-saving lamp illumination: It is a physical quantity that indicates how much energy energy of the energy-saving lamp is irradiated to the surrounding space and the ground. The more light energy the energy-saving lamp illuminates into the surrounding space and the ground, the higher the illuminance. In practical applications, the physical quantity of illuminance has practical significance. 5. Brightness and illuminance, the same points and different points of the two physical quantities: the same point is: the physical quantity that affects the brightness and illuminance of the energy-saving lamp is common, that is, the energy of the light produced by the energy-saving lamp. When the electric energy of the energy-saving lamp is constant, it is further. Understand that it should be the level of effective visual light effect of energy-saving lamps. The difference is: the light energy that affects the brightness of the energy-saving lamp is the amount of light energy radiated from the surface of the energy-saving lamp. The light energy that affects the illumination of the energy-saving lamp is the amount of light energy that the energy-saving lamp radiates onto the illuminated surface (such as the wall, the ground, and the work surface). The brightness and illuminance are different in position, the quantity relationship is different, and the external influence factors are also different. In actual production and living lighting design and measurement, the value of the physical quantity of illuminance is mainly evaluated. Second, the physical quantity of identification: Among the light energy generated by energy-saving lamps, visible light is what we need. Therefore, to identify the high and low efficiency of energy-saving lighting, the essence is to identify the effective visual light effect of energy-saving lamps. The higher the effective visual light effect of the energy-saving lamp, the better the technical quality of the energy-saving lamp and the better the power-saving effect. Third, the intuitive identification method: At this stage, the production workshop has widely used high-pressure mercury lamps, high-pressure sodium lamps, and T8 straight tube fluorescent lamps. Technical application of energy-saving lamps: It is a direct replacement for the widely used high-pressure mercury lamps, high-pressure sodium lamps, and T8 straight tube fluorescent lamps. Achieve high-efficiency power-saving, bright and comfortable technical application goals. In order to be able to visually identify the effective visual light effect of the energy-saving lamp, the "power? D? D illumination" comparison method can be used for identification. That is, by comparing the high-pressure mercury lamp, the high-pressure sodium lamp, and the T8 straight tube fluorescent lamp by comparing the energy-saving lamps, the size of the power substitution ratio can be used to visually identify the effective visual light effect of the energy-saving lamp under the premise that the illumination is relatively or improved. The greater the power replacement ratio, the higher the effective visual light effect of the energy-saving lamp, and the better the energy-saving effect of the energy-saving lamp.
