Looking at the New Industry Opportunities Behind Brightest Outdoor Led Flood Lights

With the development of our country the growth of population and industry, people growing demand for energy, and currently use most of the energy is non-renewable energy, and the energy is can cause great harm to our living environment.

So we have to solve the energy crisis is development and utilization of clean and renewable energy.

One of the most outstanding is the solar energy, using them all, limitless reserve.

The solar garden light is with solar energy into electricity.

For solar garden light in the entire work is self-sufficient and use solar energy as the load power supply, and the application of ordinary street lamp runtime takes power in a grid, the grid electricity are mostly coal and the process will produce large amounts of carbon dioxide, contributing to global environmental pollution.

Solar garden light, there is no concern on this, it is energy conservation and environmental protection, safe and reliable.

In the only way of sustainable development, including green renewable solar energy has been widely attention, strengthen the development and use of solar energy resources is one of the state policies of governments.

So from the point of view of environmental protection, sustainable development, the benefit of the solar garden light is an advantage.

Daylight lamp has widespread application in our daily life, supermarket, school, office, metro, etc. , can be seen in public places, can see the use of fluorescent lamp!

LED fluorescent lamp, energy saving and energy saving performance, after a lot of publicity for a long period of time, you have been well accepted, but spend high price to buy back the LED fluorescent tube, many are now go to a cheap energy-saving lamps in the same situation with energy saving without JieQian!

And it is a lot of waste of money, how to make the service life of the LED and brightness were satisfied to use standard, is a very meaningful topic!

LED fluorescent tube to keep long life and high brightness, power, LED light source, to solve the problem of heat dissipation, security, four key technologies.

A power supply

power first requirement is high efficiency, high efficiency products, hot stability is low, it must be high.

Usually in power supply some useful isolation and the isolation of two solutions, isolation of large volume, low efficiency, in use, the installation will create many problems, as the isolated product market prospect is big, here we mainly discuss the isolation drive solutions.


the use of the isolation of the LED fluorescent lamp power supply, with its wide Taiwan peng A704WFT of technology companies, for example, A704WFT MOS tube plugins, its basic line as shown in figure 1

the basic circuit diagram

15 application can output low voltage control, without using traditional large capacitor, can well control the output of the harmonic current;


5, the application scheme of the LED daylight A704 mature and reliable, we can provide the LED fluorescent lamp can be EMC test of PCB line and BOM information, improve the speed of the customer design and development products!

2 LED light source
adopt Taiwan ryukyu cummings patent structure LED lamp bead, the chip is placed in the feet, and heat over silver feet chips directly to the node of tropical, with traditional into products, and traditional patch products in terms of heat dissipation is different, the chip node won't produce cumulative temperature, thus ensuring the good usability of light source lamp beads, guarantee long life light source lamp beads, low light failure.


traditional patch products, although can through the chip of gold thread connection is negative, but also let the heat energy produced is chip, silver, gold wire connected to transmission of heat and electricity are by the transmission of money, the accumulation of heat in the long run will directly affect the service life of LED fluorescent tube.


traditional way of SMT products heat conduction route and the following figure 2


2 and ryukyu cummings LED transmission route and way below 3


3 ryukyu and cummings LED its patent heat dissipation structure can make the heat generated by the chip node out quickly, do not produce the accumulation of heat in the chip, so as to realize the LED light source lamp beads can be used long life.

And ryukyu and cummings company in LED the life of the test process, high and low temperature impact, reflow soldering, the application of various complex environment, such as the use of high temperature and high humidity do the complete experimental analysis, to ensure the normal use of the low light failure of long life!

Three heat
to the introduction of the infrared radiation and applied to the fluorescent tube, is an important means of improving the service life of the bulb.

Considered in heat dissipation, we will LED light source lamp beads, cooling and power of heat to separate, each other, so as to ensure the rationality of the heat dissipation.


way there are three kinds of heat conduction, convection, conduction and radiation.

Convection and conduction in a closed environment, the implementation may be small, and the heat by radiation, and is the focus of the fluorescent tube to consider.

Here is what we are doing the LED fluorescent tube in the test data, measure the temperature of the outside LED silver foot solder only 58 degrees.




test report results above data for the input power for 11.

2, luminous flux in 890 lm test report.
The highest tube temperature of 40.

213 degrees, the temperature for power capacitor can easy job for a long time, so as to ensure the long life of the power to use!

Four security

security, here basically said PC flame retardant plastic tubes, because the infrared heat radiation can penetrate the PC tube, then we design considerations LED lights, when using can more considering the safety, use of all plastic physical insulation way, even in the use of isolated power supply can absolutely guarantee the safety of use.


the LED fluorescent lamp has been quite a long time of development, from the point of the effect of energy saving, and its future application is quite broad, in addition to the energy conservation, the security, the use of long life is that we should be more attention!

security!

In the design of LED fluorescent lamp is the first element, fluorescent lamp, in PC flame retardant materials after solved the security problem, how to improve the life, the above solution presented by the various project hope for many LED fluorescent tube manufacturers to provide more thinking!

these years LED street lamp lighting technology rapid development, LED street lamp performance, now it has become the star product in city road lighting project, by the people of all ages.

Although LED lights over the years developing and perfecting, various aspects have very good performance, but still have a lot of LED street lamp manufacturers invest a lot of money to continue research and development of LED street light.

But we also know that the LED street lamp lighting technology and precipitation after so many years of development, has met with some development bottleneck blocking the LED lighting technology forward steps.
So what are the specific bottleneck?

How do we make these bottleneck, so as to create more excellent performance LED street lamp lighting products?




.

Lights, LED street lamp lighting light efficiency is higher and higher, now also in slowly closer distance with laboratory high photosynthetic efficiency, high photosynthetic efficiency is high lighting effect, but now is people's understanding in the power stage, think the LED street lamp power is the only indicator reflects the luminance of LED lamps and lanterns, resulting in the practical application of products to meet the corresponding power or regulation, and understanding of photosynthetic efficiency problem is insufficient, which limits the development of the LED street lamp lighting technology.

。

Control problem, the LED street lamp lighting technology because it has a higher controlling, so get the favour of many LED lights factory, but now has not yet formed unified LED lighting control protocol, which creates a each street lamp manufacturers lack of compatibility of control, limiting the generality of LED street lamp lighting control technology.

.

Light distribution problem, now a lot of the LED street lamp manufacturers have begun to pay attention to the light distribution of LED street lamp lighting, but not from the perspective of the humanities, the lack of humanization, cause too much now LED street lamp lighting gives a person a kind of curt lighting effect, did not play out the advantages of LED street lamp lighting technology.


the above three problems is the bottleneck of the LED street lamp lighting technology, we should be more people-oriented, considering from the user experience, considering the user's actual feeling, found the problem from the user experience, and break through the bottleneck, improve these problems, LED lights will usher in a more comprehensive development.

Nowadays, road lighting equipment in many cities use solar power and city electricity together. That is to say, many cities have installed city electricity complementary solar street lights. This is the use of solar energy on the original city circuit lights. It does not waste resources and saves a lot of costs. What is the operating structure of the complementary lighting system of solar photovoltaic power and mains power? One of the most common is low-voltage DC light source switching, which is also a control method for the use of low-voltage DC light sources in complementary solar street lights. That is, when the battery voltage drops to a certain value, the system directly switches to the mains. This system is more reliable than the battery supplementary charging mode, because it can work completely independent of the battery, even when the solar photovoltaic system fails, the solar street light can still work. The power requirement of its converter is relatively large, and it needs to be able to directly start the low-voltage DC light source. One of the most common operating structure of complementary solar street lights with commercial power is the switching of low-voltage DC light sources, which will not affect the use of commercial power and will not cause the service life of solar power.

Everyone knows that solar street lights are our company's main product, and it is also a topic that the editor talks about with everyone. Our company's solar street lights are affordable and have a long service life, which can withstand the test of time. However, the prices of solar street lights from various manufacturers on the market are different. The prices of solar street lights of the same height vary greatly, and at the same time, they are accompanied by uneven quality. Today, I will talk to you about the big price difference.


The main factors affecting the price of solar street lights are the craftsmanship of the street light poles and the size of the solar system configuration. The size of the solar system configuration is calculated according to the customer's daily requirements for lighting time and the number of continuous rainy days. Solar street lights of the same height may have many combinations of configurations, which will inevitably lead to huge price differences. In addition, street light poles are also divided into cold plating and hot plating. The price of hot-dip galvanizing process will be much higher than that of cold plating. So how do we choose?


Solar street lights currently on the market are divided into two types: V system voltage and V system voltage:
1. .V system voltage
.V system voltage solar street lights will be about half cheaper than V solar street lights in price. The main reason is that its lithium battery connection is simple and the street light pole is cold galvanized. The shortcomings of the .V solar street light are also obvious, and its service life will be about half less than that of the V solar street light. If the customer requires a longer lighting time, then its lighting effect is not ideal. The normal standard configuration of m.V solar street light is W solar panel and AH lithium battery (equivalent to one-third of the capacity of V lithium battery). The price is about yuan. If it is lower than this price, all buyers must be careful. Its configuration may be smaller and the lighting effect is even more unsatisfactory. This type of solar street light is suitable for construction companies with insufficient budget.
2. V system voltage
V system voltage solar street lights belong to the better quality category currently on the market, and its price is also not cheap. Its normal service life can reach about one year. The normal standard configuration of Mi V solar street lights is W solar panels, AH lithium batteries, and the price is about yuan. If it is lower than this price, its actual configuration may be smaller. This type of solar street light is suitable for customers who pursue both quality and lighting effects.


After reading the two kinds of solar street lights introduced by the editor above, I believe everyone should have an understanding of the reasons why the price of solar street lights is so different. In addition, the editor also tells you a little trick, when choosing solar street lights, don't be greedy for cheap, the principle of what you pay for is applicable everywhere. When shopping around, in case of uncertainty, you can choose the manufacturer whose price range is in the middle.
