The Operating Principle of LED Flood Lighting

LED flood lighting is a kind of functional lighting fixture, whose light beam is wide and average without strong directionality. When lighting up objects, the weaken speed of beam is very slow so as to give birth to a soft and transparent lighting effects. So far, LED flood lighting is widely used in outdoor environment illumination, such as for billboards, building contour, public squares, sport stadiums, factories, railway stations and harbors, etc.

What is the operating principle of LED Flood Lighting? Ultimately, it is one of LED light fixtures, which is made from semiconductors, including GaAs, GaAsP, AlGaAs and so forth. It is just a process to convert electric energy into luminous energy. It is constituted by N layer from N-type semiconductor, P layer from P-type and the active layer in the middle. After added forward biased, the electron holes in P-type area diffuse towards negative direction and enter active area. Meanwhile, electrons in N-type area diffuse towards positive direction and also enter active area. When the electrons and holes combine together, the fixture will give out light spontaneously. We always see different colors of light in the street, red, orange, yellow, green, blue and so on. How does it form? It's owing to different materials. In addition, LED light fixture would become much brighter with the increase of positive current. In a word, the stability of LED light beam is affected by the stability of current. 

The Introduction of LED Lighting Category

The Ecosystem for LED High Bay Lighting in Alibaba

 
The ecosystem in Alibaba is it's free to open a store, and when there are many LED Lights sellers they will be charged. We can't blame the platform for making profit, but the profit point in this platform is too cruel. Because the reality is if you don't strive for a sell, customers cannot see your led high bay lighting products at all, so you can either fight for it or you sell with cheap prices.
For physical stores it's easier for customers to identify the quality in led lamps stores. But on Taobao it's not the case, you can only see photos. Others sell LED flood light for only ten yuan and delivery free, and if you sell it at 50 or so, who will buy it? Does the customer actually know led chips? Do they know the material of lamp shade? It's useless to say too much, unless you are big brands like OPPLE. The customers would say your products are the same, why is yours more expensive, I would just go to other stores.
So everybody just sell at low prices. And the sales strategies everybody use? Choosing LED Lighting key words, hiring professional photographers, making up sales volume and opening Direct Train service. When the sales volume and comments reach a certain level, the sellers will apply for other group selling activities. But, have they really earned money? Only hustle and bustle.

Three Design Steps of Outside LED Lighting

At the present time, LED Lighting has been widely applied in outside areas. Therefore, how to choose the design of LED fixture becomes the primary problem that people should be considered.

First, according to the light distribution and illumination requirements of the places make sure the installation areas of fixture.

Secondly, calculate the luminous flux so that to confirm the quantity and power of fixture.

Finally, ensure the beam angle of fixture (such as LED flood light) by point-by-point method and figure out the illuminance value that needs. In order to the convenience of design, the illuminance value of outdoor is always based on the illuminance level. But in other occasion, it often needs to see the target in vertical clearly. Therefore, we must know the proportion between horizontal illuminance and vertical illuminance. Generally speaking, when the installation height is a little low or the beam angel is a little large, even though the vertical illuminance is increased, it would also produce glare.

With the continuous change of our ideology and lifestyle, there is a large variation in fixture, material, style and design method. When choose suitable lighting source, except for economical factor, we should consider the whole lighting effect and material texture, including the integration between natural environment and lighting. 

The Harm of Indoor Lighting

With the rapid development of modern society, more and more people work very late at night. Meanwhile, in many contemporary building, even in broad daylight, it still needs to open indoor lighting to work. In this condition, we must pay much attention to the harm about lighting to our body.

Scientists have been known that bright light ray is able to change the internal clocking of brain, which could control people's sleep. According to recent research, ordinary indoor light ray could affect our internal clock.

Using indoor lighting for a long period of time would change the fixed physiological model, which is not only to bring forward the maturation age, but also cause the imbalance of circadian rhythm. As a result, we may feel palpitation, chest distress or low spirit. Other researchers think that the strong light wave from indoor lighting may cause a large number of cells in our body become abnormal even death.

Working in light for a long time may make eyes tired and decrease the absorbing ability of calcium. The reason is that there are large difference between lighting and sunshine in essence and intensity. Therefore, researchers suggest that we'd better use sunshine all the day and usually open the window to let sunshine enter into the indoor.

Surely, when have to use lighting to work, we'd better pay attention to the following advice: Choose LED flood light as lighting resource. For example, when reading a book in desk, light ray should shine the whole desk. Next, make sure that lighting is on average and stable so that the lighting source doesn't flicker now and then. Finally, don't allow the light to irradiate your eyes directly. Compared with traditional lighting resource, LED light is much more benefit to our eyes. 

The Function of LED Flood Light

LED flood light, also named projection light or spot light, is mainly applied to decorative lighting in architecture. The exterior has a variety of shape, such as round or square. In order to take into account the heat dissipation, there's some difference between LED Flood Light and traditional projection light in shape.

At the present time, the LED Flood Light in the market is commonly used big power LED tube with 1W. Each LED tube contains a high photosynthetic efficiency lens, which is made by PMMA. Of course, a few companies even choose much higher power because of high-end heat dissipation technology. It's no doubt that every LED Flood Light needs a heat sink to help heat dissipation, whose size directly depends on the power of LED fixture. Throughout the whole industry, the application of LED Flood Light with big power is not very widely because of the price and high efficacy. Thankfully, this condition is gradually changing.

In general, LED Flood Light has internal control and external control. Internal control is able to built-in many kinds of changing pattern without any external controller. On the contrary, external control is just need to setup external controller to realize color change. The majority of fixtures in the market are external controller.

Up to now, the mainly application include the following areas, such as individual building and external wall of building group lighting, interior partial lighting, green landscape lighting, billboard lighting, specific facilities lighting in medical treatment and cultural center, entertainment lighting, etc. With the development of LED technology, it's believed that LED Flood Light would have totally replaced traditional projection light in the near future.  

The Installation of LED Flood Light

Actually, LED flood light is a kind of spot light, which controls lighting by built-in microchip. It is only suitable for small area lighting, and the light source is applied to LED. Even though there's not much difference between LED Flood Light and led high bay in installation, it's still worthy for use learning the process.

Firstly, make sure the fixture in perfect condition.

Before installing LED Flood Light, it is suggested to check the fixture carefully to ensure the quality after installation. There are several items that need check, including whether the feature has no damage in appearance and the accessories are all in readiness, especially purchase invoice. In this way, if the quality of fixture exist some problem, it is able to contact customer service. 

Secondly, get prepared for installation.

After check the appearance of fixture, get prepared for installation. According to the installation drawing which is provided by manufactory, test whether the fixture works well or not. In addition, get ready for all the tools and materials that need to use during installation.

Thirdly, fix and connect wire.

After arrange the position of fixture, it needs to fix and connect wire. Most of LED Flood Light is applied in outdoor lighting; therefore, it's important to promise the wire waterproof.

Finally, test light to ensure the quality of fixture.

After fix the fixture, use a multi meter to test the circuit to promise the wiring is totally correct and there's no short circuit. Then connect it into power to test light. Try to make it light a little long period of time and review it several times. 

What Is LED Flood Light?

LED flood light is a more energy efficient lighting source than traditional florescent and other types of lighting. It is can be used as both an indoor and outdoor lighting source. It is a kind of point light source, which is able to beam out at a very broad angle. Besides, the illuminated area could be adjusted freely. 

As one of the most widely light source in rendering production, standard LED Flood Light is capable to light up the whole scene. According to requirement, the scene can be used several flood lights to work in cooperation to generate much more lighting effect. It is very easy to predict the illuminated effect because of its large illuminated area. It is worthy of being pointed out that too much fixtures may be make the scene plain and dull. Therefore, LED Flood Light is not the more the better. 

When compared to standard incandescent, CFL or halogen lights, LED Flood Light has many benefits to offer users, especially longevity, less heat emission, low maintenance and replacement costs, unaffected by weather and temperature changes, free of mercury, lead. 

In the recent years, it is widely applied in many areas such as warehouses, perimeters of houses, theaters, playgrounds and stadiums. 

The Classification of LED Lighting Products

At the present time, LED Lighting products is mainly distributed into LED Lighting fixture and LED light, which replaces traditional lighting source. LED Lighting fixture means LED street light, LED flood light, led high bay, led tunnel light, LED decorate light, LED table light, etc. while the other one means LED ballast light, MR 16, T8 or T12 LED fluorescent lamp, which is capable of  directly substituting traditional lighting source.

The components of LED Lighting include LED luminous elements and matched driver, optical components, components that fixed and protected luminous elements, and integral lighting fixtures which connect fixture into branch circuit components. According to the connection methods of branch circuit components, LED lighting fixture could be divided into non-integral and integral LED light.

Non-integral LED light contains LED module, standard lamp holder and other components of luminosity, heat, machinery and electrical element. It should be installed in the fixture with standard light holder and LED driver. Moreover, it can't be directly connected into branch circuit.

In contrast, integral LED light also contains LED driver. Therefore, it is not only able to be directly installed in standard lamp holder, but also be connected into branch circuit. 

How to Choose the Accessories of LED Light

A beautiful LED Light or even an ordinary light need many accessories. When purchasing something, we always look at the appearance. If the appearance is unable to attract us, there's no need to purchase it and so is purchasing accessories of LED Light. We primarily pick up the accessories that we like.

As the saying goes, not all things that we like are suitable to us. In the fixture accessories market, we may be fond of many accessories; however, not all of them are fit for our decoration style. In order to make our home look like more harmonious and artistic, we must pick up the ones that match the house.

The most important function of fixture is lighting. Therefore, we must purchase the fixtures according to the application. For example, home is a rest place for us, so we'd better choose some soft light fixtures, such as LED down light, spot light, ceiling light. On the contrary, factory is the working place for us, so we should select high light fixtures, including led high bay, LED flood light and so on. After picking up the suitable fixtures and accessories according to the rules that mentioned above, one important thing that shouldn't be forgotten is safety. We must carefully check whether there's any problem for the quality of accessories. If so, change it at once to avoid some unnecessary trouble.

As for the price of accessories, it can't be lumped together. The price of accessories is just like fixtures, which depend on the quality, material, birth place and brand. 

The Distinction between LED Flood Light and LED Down Light

LED flood light is a kind of point light source, which is able to evenly illuminate in all directions. Meanwhile, the beam angle is optionally adjustable. As one of the most widely light source in rendering production, standard LED Flood Light is capable to light up the whole scene. According to requirement, the scene can be used several flood lights to work in cooperation to generate much more lighting effect. It is very easy to predict the illuminated effect because of its large illuminated area.

LED Down Light is also named spotlight, which is mainly used to architectural decorative lighting or commercial space. It contains much more decorative elements with round and square shape. Due to the factor of heat dissipation, there is some distinction between it and LED Flood Light.

Luminous effect: LED Flood Light can't not be used to much because too much fixtures may be make the scene look plain and dull. Therefore, it's necessary to pay much attention to consider the parameter and influence to the whole scene during design. In contrast, the beam of LED Down Light is very accurate and the aluminum reflector is extremely high in purity with optimum reflection effect. In addition, LED Down Light is attached scale plate in order to adjust beam angle.

Application area: LED Flood Light is typically applied to industrial lighting, while LED Down Light is used in household and commercial lighting.

Theses fixtures have many benefits in order to offer much more user experience. , especially when compared to incandescent, CFL or halogen lights.

1. Energy Efficiency

LED Flood Lighting can help you eliminate the need for frequent bulb replacements. This contributes to the reduction of hazardous waste. In contrast of conventional fixtures, it consumes very little electricity. A data displays that users can save as much as 80% on electricity costs by using an LED light. All in all, it is a highly energy efficiency alternative.

2. Less heat emission

The major problem with standard light bulbs is that a vast amount of the supplied energy is converted into heat. What's worse, this part of heat is wasted in vain because it dissipates in the surrounding air. However, LED Flood Lightings don't emanate heat and conserve the maximum amount of electricity. When touching an LED light which keeps working in several hours, you nearly feel any temperature. Therefore, these fixtures are suitable for warehouses lighting.  

3. Long life time

One of the most benefits of LED light is very long lasting. In an average, it lasts for up to 10 times longer than incandescent, halogen or fluorescent lights. Once you install LED Flood lighting, it's unnecessary for you to worry about replacement for a very long period of time. Even near the end of lifespan, they also don't die abruptly. Instead, they dim gradually to give you ample warning that it's time to replace the fixture.

Apart from the benefits above, LED Flood Lighting has many other advantages, including high on safety, unaffected by weather and temperature changes, free of mercury, lead and carbon pollution. As for maintenance and replacement cost, it's no need to worry about. Not mention to low cost, all manufacturers promise at least 5 years warranty after the fixtures is delivered.  

LED Flood Lighting for Commercial and Industrial Application

Are you looking for a flood light for commercial and industrial application which is not only able to energy efficiency but also environmental protection? Then LED flood lighting is the best one that you need.

In contrast of conventional fixtures, LED Flood Lighting has the following advantages:

• LED lasts up to ten times longer than other types of bulb;
• 90 percent more efficient than incandescent;
• Standard flood lights emit huge amounts of heat, which is both wasteful and dangerous. However, when touching LED, you hardly feel any temperature.
• Unlike other bulbs, LED light fixtures are less likely to break because they are stronger.
• LED is so bright that only fewer of them could light a large area.
• It is impervious to change in weather and temperature.

At the present time, LED Flood Lighting has variety kinds, such as Smart^TM LED Flood Lighting, Edge ^TM LED Flood Lighting, Apollo ^TM LED Flood Lighting while the wattage includes 50W, 100W, 150W, 200W, 300W, etc. Among of them, 100W LED Flood Lighting is the most used fixture.
