Installation method and common problems of LED light strip
The led light strip refers to the assembly of LEDs on a strip-shaped FPC (flexible circuit board) or PCB hard board. It is famous for its product appearance like a strap.
LED strips are basically divided into two types: soft LED strips and LED hard LED strips.
Features of led strip
1. Soft and can be rolled at will.
2. Can be cut and extended.
3. The bulb and the channel are completely covered with soft plastic, the insulating layer and moisture-proof effect are good, and commercial insurance is used.
4. Strong weather resistance.
5. It is not easy to break and has a long service life.
6. Facilitate the production and manufacture of graphics, text and other modeling designs.
Advantage
Flexible light strips also have substantial advantages as lights: the luminous color is varied, the light is adjustable, the color change can be manipulated, and the actual effect of solid color and RGB can be selected. Bring colorful visual impact of natural environment.
Performance parameters
1. Operating Voltage:
It refers to the input working voltage of the LED light strip. The common specifications and models are AC 12V, and some are 24V. Working standard voltage: DC12V Output power: 14.3 watts per meter / 18.2 watts per meter, optional.
2. LED color temperature:
It refers to heating a standard black font, and when the temperature rises to a certain level, the color gradually changes from dark red-light red-orange-yellow-white-blue. The temperature at that time is called the LED color temperature of the light source.
The LED color temperature of the light source is different, and the color of the light is also different:
The LED color temperature is below 3300K, and the light color is reddish to give a warm feeling; there is a calm atmosphere and a warm feeling, collectively referred to as the warm LED color temperature.
The LED color temperature is in the middle of 5000-6000K, and people have no particularly significant visual effects in this color, the actual effect of the psychological state, and they feel happy; so it is called "neutralized" LED color temperature.
The LED color temperature exceeds 6000K, and the light color is grayish, giving people a feeling of high cold, which is collectively referred to as the cool color temperature.
Under normal conditions, 7500K (cool white and gray), 6500K (true white), 3500K (warm light and dark).
3. Chroma:
Generally, different colors of LED strips will have different luminous intensities. A common enterprise is mcd, that is, millicandela. The higher the scale value, the greater the luminous intensity, that is, the brighter. It is a key indicator value for identifying the chromaticity of LED strips. The higher the chromaticity regulation, the higher the price of LED strips. This is because LED chips with high brightness are more expensive, and the higher the chromaticity, the greater the difficulty of packaging.
4. Bright angle:
It refers to the viewing angle of the LED components on the LED strip, and the viewing angle of the general-purpose SMD LED (ie SMD components) is all 120 degrees. The larger the viewing angle of light, the better the actual effect of astigmatism, but relatively, the chromaticity of the light is relatively reduced. When the viewing angle of the light is small, the intensity of the light will increase, but the range of direct exposure will become smaller.
Application field
It is generally used in bedroom decoration in home decoration.
Light strips have been widely used in decorative design and lighting fixtures in buildings, highways and bridges, pavements, gardens, courtyards, wooden floors, suspended ceilings, furniture, cars, fish ponds, underwater, advertising, billboards, signs, etc.
In addition, the return of various festive themed activities such as Christmas, Halloween, Qixi Festival, Easter activities, National Day, etc. has added endless joy and festive atmosphere. It has entered advertising, decoration and design with strong and unyielding vitality. , engineering construction, business, gift five advantages sales market, and sold to Japan, EU countries, Australia and other countries and regions. It is widely used in door contours, highway bridges, guardrails, hotel restaurants, forest gardens, karaoke halls, design and decoration venues, etc.
