According to my math, the new bulb will put our 15 fewer lumens than the original and be dimmer than the original because of it.60 lumens is pretty fim in any case. If you want it dimmer, why not just disconnect it and not have to go up 7 meters in the air? A 1000W Metal Halide lamp puts out 60000 lumens. That is more normal for a street lamp, since the purpose is to provide light at street level. 60 lumens would merely be a glow at street level.Even if your decimal was moved 3 places to the right, you would still be replacing a bright light with a dimmer one. Why would you want to do that? Street lights also help to deter property crimes and drug deals. I live in Atlanta and used to do lighting occasionally. When I had to replace lamps and ballasts in high crime areas where drug deals normally took place at night, almost invariably, the lamps and ballasts of the fixtures that were out, there was a bullet hole all the way through the fixture. Lamp ballast and all. Tgis was done so the criminal transactions could take place without a bright light light directly overhead. Hope this helps. Hope that helps. What will be the difference in lumens if I replace 60 watts LED bulb with 45 watts LED on 7m high solar street light?
1. Note the details of the battery in the use of solar street light fixtures.
Solar street light fixtures are the most common solar products in our daily life. The battery is one of the main pieces of equipment for solar lamps. It exists to preserve the energy converted from sunlight and convert it into light energy at night to serve our daily lives. Therefore, the quality of the battery and the specification and attention to detail determine the service life of the solar street light fixture. The maintenance-free lead-acid battery component in solar street light fixtures is very important. It is also known as a valve-regulated sealed lead-acid battery. It has safety and reliability and is not afraid of vibration, low water loss, low self-discharge rate, and good low-temperature startup performance. Of course, the service life of solar street light fixtures is generally comparative, but many friends have responded that batteries often fail, so what are the prevention methods? Here are a few ways to share with you, I believe it will help a lot of friends. The depth of discharge of the battery is closely related to the number of charge and discharge cycles designed by the battery at that time. Generally, the charge and discharge cycle of the lithium battery is twice or three times that of the ordinary battery, and its service life is relatively long. An excessive discharge will cause the battery to no longer be activated to its best condition or even scrapped. The life and performance of a solar street lamp battery are closely related to the accumulation of heat generated inside it. The heat source inside the battery is mainly generated by the power loss of the internal electrochemical reaction, and the product of the charging voltage and the charging current can be simply seen. In the oxidation reaction, the float charge flow is increased to generate more heat, and during constant voltage charging, the float charge flow increases with temperature, thereby further raising the temperature. The thermal runaway phenomenon is a special phenomenon caused by the structure of the valve-controlled sealed battery. Thermal runaway often causes serious damage, and in serious cases, the battery is scrapped. In the process of using solar street light fixtures, as long as you pay attention to the above two points, you can effectively prevent damage to the battery and avoid the service life is greatly reduced, resulting in increasing use costs.
2. Design and simulation of the solar street lighting photovoltaic system with LED energy lamp
Currently, existingtechnologiesofenergygenerationbasedonfossil usually accompanied by burning of gases resulted in excessive amount of CO2 emissions. The national oil consumptions of kingdom of Saudi Arabia (KSA) is increasing by 7% annually. If this growth rate continuous, the local demand will tremendously increase in a decade. This study has covered a solar photovoltaic system in a Tent City (Mina) during Al Hajj period. The Al Hajj is an important to every Muslims since it needs to be performed only one time in their life. Al Hajj ritual is performed in Makkah city, Saudi Arabia. A part of this ritual is staying in the tent city (Mina) for a few days, which has approximately 160,000 tents for sustaining around 3 million pilgrims. During Al Hajj period, Saudi Arabia is feeding the Mina with high amount of electrical energy to serve pilgrim's need such as air-conditioning, lighting and external outlets. In this research work,solar energy is used to supply electricity to tents by using solar panels. Each Tents can be fitted with solar panels to cover the electrical needs. The design aspects of supplying the accurate amount of energy are studied. The design of solar PV system, such as design and selection of panel, inverter, and battery,are investigated. In this article, the calculation of the tent area, arranging panels, actual capacity of the battery is performed. The result shows how the solar PV system is used to increase efficiency, reduce power consumption, cut cost, reduce the demand of fossil fuel and eliminate carbon emissions. The primary function of this article is to use solar photovoltaics on- grid system in order to reduce the energy consumptions of the tent city (Mina) during Al Hajj period. Keywords:Solar energy, Solar Photovoltaics; Renewable energy; Solar on-grid system; PV efficiency.
3. How to maintain solar street light in summer
With the temperature rising in most parts of the northern hemisphere, most areas enter the hot summer, and the lively night activities are also on the scene, barbecue, square dance, night running, night market, and noisy children. This time a good lighting environment is provided. A lot of conveniences. Because of the convenient construction and the trouble of the mains wiring, solar street light plays an increasingly important role in outdoor lighting, but because many people do not know much about solar street light, they often have various problems during use. First, a common problem is battery feeding. As a manufacturer specializing in the production and installation of the solar street light, we have recently received relevant consultations. We believe that solar street lights are not bright because of the reasons for feeding. Battery feeding may be caused by excessive battery life and normal loss; it may also be that the construction party cuts corners when the construction is first, or the quality of the product purchased by the consumer is cheap but not cheap; or the installation location is not Too reasonable, the green plant is blocked as a feed. At this time, it is generally necessary to replace the new battery or cut off the green plant cover. Secondly, the summer rain increases the solar street lights to enter the water. Now the street light waterproof level is above IP65. There is no problem in normal outdoor use, but it does not rule out the use of improper installation or some manufacturers' product quality is not enough to cause the lamp to leak, so there is no problem. At this time, it is generally necessary to replace the street light. Third, damage to other accessories. In the summer, there are many situations such as strong winds or heavy rains. We often see the phenomenon that the street light poles are tilted to the ground on the road. As a whole system, solar street light is damaged during the use due to various reasons. At this time, professional maintenance and inspection personnel are required to check the reasons. In fact, there are many methods, which require the user to constantly summarize in the process of use, find the problem and feedback the problem to the manufacturer in time. Only in this way can we avoid these things more effectively.
