There are many standards to consider for the layout of office lamps: 1. ** Illumination standard **: - The standard value of illumination for the working surface of an ordinary office is 300lx according to the standard value of GB50034 - 2013. - The illumination of the background area of the work surface should generally not be lower than 1/3 of the illumination of the adjacent area of the work surface. - The illumination degree must be no less than 0.6 (the ratio of the minimum illumination on the specified surface to the average illumination). 2. ** Glare Control **: - To avoid glare, glare can be produced by direct glare (light that enters the eyes in normal vision) and reflected glare (such as reflecting light from a lamp through a computer screen, causing glare or affecting the observation of screen text). - Diffuse lamps and other methods can be used to reduce the impact of glare. 3. ** Lamp position **: - The general lighting should be on both sides of the work area, and it is not advisable to arrange the lights in front of the work position. When it is difficult to determine the work position, choose a lamp with a large luminous area. 4. ** Illumination Method **: - All the lights were down (such as embedded and ceiling), and the lighting was even but the ceiling was darker; the semi-indirect lighting had light up and down, which was more comfortable and energy-saving; the light of the lamp was completely up, and the space was illuminated by the reflection of the ceiling. The view was more comfortable but it might waste energy. 5. ** Combination with the environment **: - The reasonable lighting arrangement should match the office decoration style of different spaces, beautify the office environment, and combine with natural lighting to form a comfortable lighting environment. 6. ** Energy Saving Requirement **: - When an ordinary office reached 300lx, only 9W/m2 of electricity was allowed; when a high-end office reached 500lx, only 15W/m2 of electricity was allowed. By controlling the lights reasonably, such as giving a separate switch to the lights by the window so that they could be turned off during the day when the light was good, it could save energy.

There were several inspirations from the story: - When faced with difficulties, one should not be completely overwhelmed by the difficulties, but should actively seek suitable solutions. Just like Cao Cao, when his soldiers were thirsty but had no water to drink, he used the method of "looking at the plum blossoms" to temporarily relieve the thirst of the soldiers, so that the soldiers could recover their physical strength and continue to move forward.

What should I do if the gardenia turns yellow and withers off its leaves?

The yellowing and withering of gardenia leaves can be caused by a variety of reasons. The following are the corresponding solutions: 1. [Soil Acid and Alkaline Problem: The gardenia flowers like acidic soil and have a high demand for iron.] In the north or in small pots, if the soil was often watered with alkalized water, it would easily lead to alkalization of the soil and cause yellow leaves. The new leaves were green in color, and the other parts were yellow and gradually spread. If there are just a few leaves that have turned yellow, you can use a 1:1000 ratio of Fe2SO4 solution to water it once a month, but don't spray the leaves to avoid burning them. If the whole plant is yellow and the root system is weak, the effect of watering with Ferrous Sulphate is not good. You can forcefully cut the branches, remove the bare roots, and then use half of the fermented pine needles to mix with the soil with good acidic breathability to replant, so that it can take root and grow leaves again. 2. [Water Rotten Root Problem: Water will cause the roots to rot, causing the leaves to turn yellow and dry.] At this time, he needed to trim the flowers and rotten roots to nurture them. 3. ** Not enough light **: The lack of sufficient light will cause the leaves to fall. It should be ensured that there is a longer period of light every day. 4. ** Problems with fertilizers ** - ** Over-fertilisation **: The leaves will turn yellow after fertilisation. If it is not serious, you can water it more to let the fertilizer flow out with the water. If it is serious, you need to change the soil again. - ** Lacking fertilizer **: Lacking fertilizer will cause the new leaves to turn light green, while the old leaves will start to spread out from the veins and turn yellow. During the flowering period, it can be used with monocratic phosphorus, and during the growing season, it can be used with multi-element fertilizers. 5. ** Water shortage problem **: The yellowing and withering of the leaves may be caused by water shortage. The watering amount needs to be adjusted. 6. ** Sun exposure **: The yellow spots on the leaves may be caused by the sun exposure. They should be moved to a cool place for maintenance. 7. ** Temperature-related issues **: Gardenias prefer warm and humid environments. If the temperature is too high in summer or too low in winter, it will cause the leaves to turn yellow. Therefore, temperature regulation is required. 8. ** Changing pots will hurt the roots **: When you just change pots, the roots will be weak, and the bottom leaves will be consumed. If the leaves are seriously yellow and fall off, it is a sign of lack of fertilizer. You need to replenish the fertilizer regularly. 9. ** Lacking Elements ** - Iron deficiency: The young leaves lose their green and yellow color between the veins, and the entire leaf gradually turns yellow-white to white. It is commonly found in calcareous soil and alkali-earth soil. Too much phosphorus and calcium in the soil will also affect iron absorption. 0.5% Ferrous Sulphate can be used to supplement iron. - ** Magnesium deficiency **: The old leaves in the lower part of the plant will first lose green and yellow. The acidic red soil is easy to lose the calcium. The excessive amount of potassium and potassium in the nutrients will produce resistance to the calcium ions, which will also cause the yellow leaves.
