Four kinds of installation
1.Indoor installation: it is easy to install led strips which are used in indoor decoration, because it does not damaged by storm and wind. There is 3M double faced adhesive tape in the back of some rgb led strips, and it is easy for installation, because it can be fixed on the wall by double faced adhesive tape. And every 3 led lights can be cut off to put into use alone.
2.Outdoor installation: the strips in the outdoor may be damaged by storms, so it is fixed by waterproof glue and slot.
3.Power connection: in general, the voltage of led strips is 12v, so switching power supply is needed, and its size is decided by the power and length of led strips.
4.Controller connector: 5050 smd strip and RGB led strips should be controlled by controller to achieve the transition effects. However, every controller can control different distance, so if the connecting distance is long, while controller can’t control it, then power amplifier is needed to tap.
5.Pay attention to the connecting distance of led: in general, if the connecting distance is beyond led strips’ distance, led strip will easily produce heat which will affect its working life.
Eight reasons to explain led’s failure
1.Imperfection of led package damages the bulb during the transportation.
2.There is weak jointing in led strip, the vibration of transportation makes soldered dot fall down, and prevents the strips working.
3.Solder in small quantity makes soldered dot fall down.
4.Poor-quality soldering makes led strips easy to fall down and crack.
5.The installation angle is too big to separate soldered dot and copper foil.
6.Over extrusion of products during installation damage led strip chip.
7.Solder mask of circuit board is too thick, which prevents the mix of circuit board and soldering tin.
8.Led strips cannot be distorted in the process of installation.
Two kinds of driving power supply
Led strips have to work with driving power supply, led in different environments need different driving power supply. And it can be divided into two kinds.
1.According to the type of driving ,it can be divided into constant-current type and voltage regulator
2.According to the structure of circuit, it can be divided into electronic transformer, dropping resistor, conventional transformer, and RCC switch power supply. We should take care of the led strip in order to make them work more efficiently and better. At the same time, led industry will have a brighter future.

Methods to Indentify the Quality of Led Strips
Classification of LED strips
Led strips refer to assembling led in the ribbon pattern FPC or PCB, and it is called led strips for its shape just likes a string. It is getting more and more achievements in decoration industry or the concept of environmental protection and its long life (its normal working life is about 80000-100000 hours). Led strip can be divided into two kinds: flexible led strip and led light bar. 1. Flexible led strip is assembled by FPC and 5050 smd strip whose thickness is only the thickness of one coin, which takes up almost no space. Its normal standard is 30cm’s long with 18 led lights, 24 led lights and 50cm’s long with 15led lights, 24led lights, 30led lights, and so on. And it can be cut and prolonged arbitrarily without affecting its lighting. The material quality of FPC is soft which can be bended, folded and winded, and it is can be moved and stretched out or drawn back in 3D space without breaking off. Therefore it is suited to be used in irregular and narrow space, and it is fit for any patterns in advertisements. 2. LED light bar is assembled by PCB and smd led. The advantages of led light bar is easy to fix, and convenient to process and install, while disadvantage is that is cannot be bended arbitrarily or used in irregular place.
Tips for indentifying the quality
The good and bad led led light manufacturer are intermingled, and the price is also different form one enterprise to another. A large number of customers are not qualified the ability to identify the quality from the aspect of professional technology. However, we can roughly judge it through appearance. 1. Regular led strip manufacture use the technology of SMT, and the led strip is produced by solder paste and reflow soldering. Hence the welding spots are smooth and the y will not in large number. 2. FPC can be divided into polygon and rolled copper. The copper foil in polygon plate protrudes from it which can be judged by juncture, while rolled copper is closely connected with FPC. 3. The led strip produced by SMT technology possesses excellent cleanliness without any impurities or besmirch. 4. Regular led strip will be attached with instructions and datasheet.
Development of Led strips in the future
In the modern society, more and more industries need led technology to help them promote the image of enterprises and products which make led industry into the hottest discussion in this age. Furthermore, with the development of newly advanced technology, there is no doubt that led strip will take up the whole market.

Introduction of Decorative LED Lighting
Principle of High-power LED Floodlight
The floodlight is the most widely used light source in making effect drawing. The standard floodlights are used to illuminate the entire scene. There can be several floodlights in the scene to produce a better effect. Its function is to uniformly illuminate objects from a specific point in all directions, and it is best to compare it to the light bulbs and candles. Floodlights can be placed in anywhere of the scene. For example, it can be placed in the outside of the camera range or inside of the object. The floodlights are widely used with many different colors in the scene from a distant place. These floodlights can be dark projection and mixed model. As high power led flood light irradiation range is relatively large, so irradiation effect of floodlight is very easy to predict, and this light also has many auxiliary purposes. For example, place the floodlight is in a position close to the surface of the object, then it produces a bright light on the object surface.
Features of High Power LED Floodlight
Under small current, temperature rise of LED floodlight is not obvious. If the ambient temperature is high, the main wavelength of the LED floodlights will red shift, its brightness will decline, luminous uniformity and consistency becomes poor. Particularly the temperature rise of the large display LED floodlight has obvious effect on the reliability and stability. More significantly, the thermal design is critical.
Advantages of LED SMD Strip
LED flexible light strip is also known as flexible neon tube. Especially the 5050 smd strip is recently the latest and most popular LED strips in the market for festival decoration. Compared with the glass neon tubes, 5050 SMD strip has the following advantages: 1, High in brightness: Its light source is made of imported high brightness LED series, per meter 80LED / m or 90LED / m arrangement of encryption is the fundamental guarantee of the overall glow and high brightness. 2, Longevity and durability: Based on LED technology, the new structure in any case, can achieve ultra-long service life of more than 100,000 hours, compared with the glass neon lights, its durability goes without questioning, because there is no need to consider the broken glass neon (PVC plastic lamp body). 3, Flexible and energy-saving: The SMD LED strips can save more than 70% of the energy power consumption costs. 4, Soft: Flexible SMD LED lights can be bent to a minimum diameter of 8CM, and can be cut at any scissor mouth shear, so it can be bent into a variety of texts and graphics.
