light strip
Light strip refers to the special processing technology to weld the LED light on the copper wire or the strip flexible circuit board, and then connect the power supply to emit light. Some people consider saving electricity and choose not to use light strips. There is obviously a big difference between having light strips and no light strips. LED light strips can relieve everyone's concerns, because LED light strips use LEDs to emit light, so that the service life of LED light strips can reach 50,000-100,000 hours of uninterrupted use, and it saves 75% of electricity compared to ordinary light strips. , The surface temperature of the LED light strip is very low, which also increases the service life of the LED light strip.
LED light strips are divided into flexible LED light strips and LED hard light strips. The differences are as follows:
1. The flexible LED light strip is assembled with FPC as the circuit board, and assembled with SMD LED, so that the thickness of the product is only the thickness of a coin and does not take up space; the general specifications are 30cm long with 18 LEDs, 24 LEDs and 50cm long with 15 LEDs, 24 LEDs, 30 LEDs, etc. There are also 60cm, 80cm, etc., different products have different specifications. And it can be cut at will, and can also be extended at will without affecting the light. The FPC material is soft and can be bent, folded, and rolled at will, and can be moved and stretched freely in three-dimensional space without breaking. It is suitable for use in irregular places and places with small space, and because it can be bent and rolled arbitrarily, it is suitable for any combination of various patterns in advertising decoration.
2. LED hard light strips are assembled with PCB hard boards. LEDs are assembled with SMD LEDs, and they are also assembled with in-line LEDs. Different components are used depending on the needs. The advantage of the hard light bar is that it is easier to fix, and it is more convenient to process and install; the disadvantage is that it cannot be bent at will, and it is not suitable for irregular places. There are 18 LEDs, 24 LEDs, 30 LEDs, 36 LEDs, 40 LEDs and many other specifications for SMD LEDs for hard light bars; 18 LEDs, 24 LEDs, 36 LEDs, 48 ​​LEDs are used for in-line LEDs. And other different specifications, there are front and side, and the side light is also called the Great Wall light bar.
LED light strips and LED light strips have gradually emerged in various decoration industries because of their long lifespan (generally, the normal lifespan is 80,000 to 100,000 hours) and green environmental protection. LED strips and strips are now widely used in furniture, automobiles, advertising, lighting, ships and other industries.
light strip. It is the abbreviation of LED light strip. Most people are not used to the long term when they say it, so the LED in front is omitted, and it is directly called the light strip. In this way, the name of the light strip also includes many old-fashioned light strips that use wires to connect LEDs directly without FPC or PCB. Of course, it also includes flexible light strips and hard light strips.
Light. This is the abbreviation of PCB hard light bar and Great Wall light bar.
LED Strips. This is the English name of the LED light strip. The interpretation of Strip in Yahoo's translation is "strip", and the interpretation in Google's translation is "strip", but the noun of LED light strip in the mouth of foreign customers is LED Strip.
Flex LED Strips. This is the English name of the flexible LED strip. The interpretation of Flex in Google's translation is "flexible", but the interpretation in Yahoo's translation has become "conductive thread". But the Flex LED Strip mentioned by foreign customers is what we call flexible LED strips in China.
LED Light Bar. This is the English noun of LED light bar. The interpretation of Light Bar in Yahoo's translation is "light band", but the interpretation in Google's translation has become "in view of the bar". It seems that each translation is different, but foreign customers are used to calling LED light bar LED Light Bar.

LED downlight
It is for decoration and emits a faint light, but it will get brighter and brighter, very warm.
Downlight is a kind of lamps with more condensing properties than ordinary surface-mounted lamps, and is generally used for general lighting or auxiliary lighting.
A spotlight is a highly concentrated light fixture that emits light with a specific target that can be specified. It is mainly used for special lighting, such as emphasizing a very interesting or innovative place.
LED spotlights are used like flashlights and are generally used outdoors. There are also indoor ones, because the varieties are different, so the uses are also different.
LED spotlights are made of metal materials with good heat dissipation performance; various colors of ultra-high-brightness LED lights are, which are combined after testing and aging; can be used continuously for 35,000 hours; power: 1.8W, 3.5W, 4W (you can choose by yourself ); The operating voltage is DC/AC12V, 24V, 110/220V;
Features of spotlights:
1. Power saving: The reflector of the spotlight has a strong refraction function, and the power of about 10 watts can generate strong light.
2. Concentrated light: The light is concentrated, which can highlight or emphasize an object or space, and the decorative effect is obvious.
3. Comfortable: The color of the spotlight is close to natural light, reflecting the light on the wall without dazzling.
4. Many changes: You can use small light bulbs to make different projection effects.
Classification of spotlights:
1. downlight. It can be installed on the ceiling, above the head of the bed, in the cabinet, and can also be hung, floored, or suspended in the air. The characteristics of the downlight are that the light source is partially illuminated and scattered freely from top to bottom, and the light source is closed in the lampshade. Slot downlights and downlighting wall lamps, etc., can be installed in the porch, living room and bedroom respectively. For example, a green porcelain shade under the wall lamp is installed near the TV, which can be seen clearly without affecting TV viewing. A sleeve-type downlight is set above the sculpture shape, which can lead people's eyes to the artwork for easy viewing. Choose a downlight, the wattage should not be too large, it is only for lighting, and it should not be dazzling.
2. Track spotlights. Most of them are made of metal spraying or ceramic materials, and there are pure white, beige, light gray, gold, silver, black and other tones; the shapes are long, round, and different in size. The light beam projected by the spotlight can be concentrated on a painting, a sculpture, a pot of flowers, a fine decoration, etc., or it can shine on the back of the swivel chair where the owner of the room sits, creating colorful and magical light and shadow effects. Can be used in living room, porch or bedroom, study. There can be one or more lights, the shape and color of the spotlights.

There are many categories of LED light strips. How to choose a light strip among the dazzling light strip categories?
The purchase of LED light strips is a skill. When purchasing LED light strips, you can identify the quality of the light strips from the following 6 points:
1. Look at the solder joints
The light strips produced by regular LED light strip manufacturers are produced by SMT patch process, solder paste and reflow soldering process. Therefore, the solder joints on the LED light strips are relatively smooth and the amount of solder is not much, and the solder joints are semicircular. The arc extends from the FPC pad to the LED electrode, while the amount of solder in the solder joints of the copycat LED strip is uneven, and more than one dot wraps the solder feet, and there will be tin tips to varying degrees. This is manual soldering. typical phenomenon
2. Look at the packaging
Regular LED light strips will be packaged in anti-static coils, usually 5 meters or 10 meters, and then sealed with anti-static and moisture-proof packaging. The reel, and then there is no anti-static and moisture-proof packaging bag. If you look closely at the reel, you can see that there are traces and scratches left when the label is removed.
3. Look at the labels
Regular LED strip packaging tapes and reels will have printed labels instead of printed labels, while the copycat version of the label is printed, and the specifications and parameters are not uniform.
4. Look at the cleanliness of the LED strip surface
If the LED light strip produced by the SMT process has a very good surface cleanliness, no impurities and stains can be seen, but if the hand-welded LED light strip is used, no matter how the surface is cleaned, there will be stains and cleaning traces left. At the same time, there will be flux and slag residues on the surface of the FPC.
5. Look at FPC quality
FPC is divided into two types: copper-clad and rolled copper. The copper foil of the copper-clad plate is protruding. If you look closely, you can see it from the connection between the pad and the FPC. The rolled copper is closely connected with the FPC and can be bent arbitrarily. If the copper-clad plate is bent too much, the pads will fall off. If the temperature is too high during maintenance, the pads will fall off.
6. Look at the attachment
Regular LED light strips will be accompanied by instructions for use and light strip specifications in the packaging box, and will also be equipped with LED light strip connectors or card holders, while the knockoff LED light strip packaging box does not have these accessories.
