谁能帮忙翻译一下啊（2）？昨晚发过的，怎么现在连我的提问里都完全没有提问的记录呢？

lamp 's main role ** to light source luminous flux d**tribution in a required direction, to improve the utilization rate of the light and to **oid glare. therefore to promote energy-efficient lighting work, efficient and reasonable light d**tribution has great potential of energy s**ing lamp. selection, attention should be paid to lighting reflectors, high-efficiency reflecting plate ** a range of lamp tube and the lamp holder of new structure reflecting device, the main technology ** the application of point source reflection optical principle, as well as the improvement of optical curvature, with the nano coating mirror surface treatment, surface with conc**e and convex nest surface structure, make the product itself light reflectivity more than 99%, the utilization rate of the light source to light output limit. in the selection of high reflector lamps at the same time we should pay attention to choose the good performance of the hood, such as glass or organic glass; to ensure the sealing performance, as far as possible to reduce the loss of light caused by water pollution. luminaire efficiency ** defined in terms of measured under conditions of light emitted flux value and all the light emitted from the lamp luminous flux determination values of the ratio of. any material made of lamps for light radiation flux after reflection and transm**sion, its efficiency ** always less than 1. assuming that the same power source with high efficiency, a lamp, the light flux of 70% - 80% are used, one with low efficiency of the lamp, luminous flux ** obtained using only 40% - 50%. compar**ons between the low efficiency of the light source, lighting power consumption nearly 30% wasted, failed to play its role, th** point ** often neglected. therefore, selection of lamps should be chosen as the light d**tribution curve ** good, high efficiency lighting. in addition, in the process of using the lamp will inevitably be pollution, ** bound to cause the loss of light, regular maintenance ** to ensure the normal operation of electrical equipment and the basic guarantee of the light source, otherw**e the power consumed by the most wasted. therefore, selection of lamps to select the sealing performance can reach more than ip55lamps, in order to reduce the workload of maintenance. in lighting design, lighting light source selection should also be cons**tent with the relevant current national standards, should be based on different occasions, all kinds of energy-s**ing light source efficiency and main technical index to choose, so that it ** possible to achieve high efficiency of light, lighting energy s**ing.to reduce the power loss of power supply3, narrowing the d**tanceat present, city zero after load reduction, voltage ** elevated, so not only shorten the service life of the lamp bulb, also increased the unnecessary energy consumption. in th** case, can install an intelligent lighting power s**er. intelligent lighting power s**er used in street lamp system with efficient energy-s**ing effect, ** the use of microelectronic technology in street lamp power supply system electrical energy quality optimization. without affecting the normal operation of the equipment under the prem**e, it outputs a optimal power ( optimal illumination ), s**ing electricity and prolonging the service life of electrical equipment of double effect. intelligent lighting power s**er cons**ts of microprocessor real time dynamic prec**ion detecting and monitoring, to achieve high power voltage, uninterrupted low current switching technology, and according to the actual need of optional transition-optim**ed control mode, illumination control mode, the remote computer centralized control mode, to realize intelligent lighting. control program after setting according to the setting program, the device will automatically adjust the lighting load voltage and current, balance control power output, improve power factor, reduce reactive loss, achieve the purpose of s**ing electricity. in lamp design also needs to control power supply line, reasonable selection of wire section, reduce because the line too long to produce voltage loss. 20210311
