What Will Be the Difference in Lumens If I Replace 60 Watts LED Bulb with 45 Watts LED on 7m High So

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.

Development Direction of Solar Street Lamp Manufacturers
Development Direction of Solar Street Lamp Manufacturers
There are many solar street lamp manufacturers. In the face of fierce competition in the industry, solar street lamp manufacturers have to face some problems if they want to develop. If they want customers to find you or patronize you again, the premise is that you are a good manufacturer in all aspects, What kind of development direction should solar street lamp manufacturers have now?If the solar street lamp price has an impact on customers, it can only be that the solar street lamp manufacturer has not really succeeded. Because the price war is never an inevitable factor for the development of manufacturers. Today, you can give customers a very low price and reduce the street lamp price by reducing the Watts actually needed by customers. It may not be guaranteed that another manufacturer will use the same method to reduce the price and attract customers. You are lowering the price, and your opponent is also lowering the price. In this way, long-term development will only hurt both sides.Therefore, the price war is not the correct development direction of solar street lamp manufacturers. The correct direction should be to focus on product production, improve product quality and cost performance, and do a good job in after-sales service at the same time. It's like a 99 yuan smartphone and a Samsung phone with hundreds or even 3000 yuan. There is a big difference in price, but we still choose Samsung phone because of its high brand, good performance and cost performance in all aspects. Therefore, the development direction of solar street lamp manufacturers should not tangle in price, but do a good job in their products and improve their brand.
Industry: LED Industry Reshuffle Through Three Forces
Industry: LED Industry Reshuffle Through Three Forces
The collapse of small and micro led enterprises last year has opened the curtain of the reshuffle of China's LED industry. Since the beginning of this year, three major factors, such as the rising threshold of government procurement, the continuous tide of IPO listing and the introduction of industry standards, will accelerate the process of reshuffle in the LED industry.On March 20 this year, the "2012 financial subsidy promotion project for semiconductor lighting products" organized by the Ministry of finance, the national development and Reform Commission and the Ministry of science and technology held a domestic public bidding in Beijing, involving led downlights and reflective self ballasting LED lights for indoor lighting, LED street lights and led tunnel lights for outdoor lighting, Nearly 300 bidding representatives from 110 enterprises across the country participated in the bidding activities.The national development and Reform Commission made it clear that in 2012, the Chinese government will spend 40 billion yuan on the procurement of LED street lamps and provide 30% financial subsidies to LED street lamp users. Since March this year, all lighting projects and new planning areas invested by the provincial government have used LED electrodeless lamps in the field of public lighting, which is estimated to bring a market of hundreds of billions of yuan.Don't think that the government will "sprinkle pepper" again. An entrepreneur who participated in the bidding on March 20 revealed that the national bidding raised the threshold. For example, products should have energy-saving certification. The province also invited tenders for LED products entering the indoor lighting of public works this year. So far, downlights of 3 enterprises, spotlights of 3 enterprises, bulb lamps of 6 enterprises and fluorescent lamps of 22 enterprises have won the bid.Facing the industry pattern of "small and scattered", the government began to realize that it is necessary to support powerful enterprises to become bigger and stronger.More and more led enterprises are listed, which will become another important force for industry integration. After development in recent years, the total number of Listed Companies in the LED industry has been close to 40, and not a few are lining up for listing. It is expected to produce some industry leaders who can compete with international giants.According to the data of provincial Lighting Appliance Association, from 2010 to now, more than 100 LED projection lamp enterprises have completed the share reform, and the Pearl River delta accounts for 51.5%; The listed led enterprises account for about 61.5%, including Hongli optoelectronics, Zhouming technology, etc; There are also some ready to be listed, such as Shenzhen Jiawei Co., Ltd., which exports solar LED outdoor lights for 1 billion yuan a year, and will be listed soon.After the listing of led enterprises, it is not only conducive to establish their own good brand image in the chaotic market, but also can use capital means to acquire and merge, expand themselves and purify the market. Zhouming technology said that if it encounters a good project, it does not rule out the possibility of acquisition.The third force of integration comes from the continuous improvement of industry standards. The national standardization management committee recently held the first working meeting of the semiconductor lighting standard leading group, involving the national development and Reform Commission, the Ministry of science and technology, the Ministry of industry and information technology, the Ministry of housing and urban rural development, the Ministry of Finance and other departments. This is the first time that the industry has uniformly planned and deployed the semiconductor lighting standardization work at the national level Light source and lamps, lighting application and energy efficiency.The Provincial Department of science and technology will also announce the progress in the formulation of semiconductor lighting standards this week. At present, 130 standard items have been listed, and led enterprises can participate in the revision of industry standards through bidding.It can be predicted that with the gradual improvement of industry standards, the LED metal halide lamp industry will bid farewell to the mixed situation. In the upcoming 12th Five Year Plan for semiconductor lighting, the state pointed out that by 2015, the scale of semiconductor lighting industry will reach 500 billion yuan, and cultivate 20 30 leading enterprises with independent brands and independent intellectual property rights, and 40 50 innovative high-tech enterprises
I Would Like to Ask What Are the Ways to Improve the Brightness of Solar Street Lamps?
I Would Like to Ask What Are the Ways to Improve the Brightness of Solar Street Lamps?
I would like to ask what are the ways to improve the brightness of solar street lamps?1. Determine the brightness of LED solar street lamp before purchaseBefore purchasing solar street lamps, if it is a large number of recycling, the best thing is to choose manufacturers with industrial plants and drive to the processing plant to have a look. If you decide where to buy, you must talk to the other party about the regulations on chromaticity. If you don't have much definition of this chromaticity, you can let the other party make a sample to have a look.If the requirements for chromaticity are very high, the size of LED light source should be larger. Some manufacturers will choose the most suitable scheme for you out of your own consideration. If it is not particularly bright according to your specific situation, you can also listen to the manufacturer's suggestions.2. Lower the LED solar street lamp equipmentIf solar street lamps are to be installed on both sides of the road, we should fully consider whether there are green plants on both sides of the road. Because the solar street lamp is converted into electromagnetic energy by digesting and absorbing solar energy, if something blocks it, the actual effect is undoubtedly impossible to be very good. When such a situation does occur, why not reduce the height of the solar street lamp and not completely cover the solar panel.3. Query LED solar street lamps on timeMany solar street lamp projects are not easy to hold meetings after the equipment is good, which is naturally not very good. Although solar energy does not need maintenance or cleaning by full-time personnel, it must be queried on time. The damaged position should be repaired immediately. If the solar panel has not been removed for a long time, it also needs to be inadvertently scrubbed.

This Can Be Done When the Solar Street Lamp Cannot Work (I)
1 Power loss of solar street lamp: the power loss of solar battery is due to the quality problem of the battery itself. The cheapest one is 2-3 yuan 1Ah. Generally, this is not very reliable. Problems continue to occur after using it for about a year. Therefore, to solve this problem, replace the solar battery and replace it with a better manufacturer, If it is a northern city, it should also be noted that the battery must be buried below the frozen soil layer, especially in cold places. Thermal insulation cotton should be added to the battery, because the capacity of solar energy storage battery has a great relationship with the external ambient temperature.2 The LED light source of solar street lamp is not on: it may be the most direct way for the performance of solar street lamp. The solar street lamp system is abnormal, that is, it is not on. One of the reasons why the solar street lamp is not on may also be the problem of LED light source. As a general purchaser, it is difficult to distinguish high-power LED light source. If the solar street lamp is not on, You can simply check the light source by yourself. If the system is small and the system voltage of the light source is 12V or 24V, the conventional configuration is used. The best way to detect the light source is to connect the battery directly to the light source. If the light is on, it proves to be normal.For more questions, please click the right figure to consult online customer service.
