2.How does the addressable light strip work?
An addressable RGB light strip is composed of integrated circuit chip, LED, controller and power supply.All LEDs (red, blue and green) have dedicated ICs that can be individually addressed.The controller has a data channel for relaying commands.
The LED strip itself cannot do anything, the user must control them through the GPIO pins on the microcontroller and the programming code.Several libraries of different types of LED strips are provided, which can be used to develop code.By using these libraries, users can not only address each LED, but also have better color and brightness control for each LED.
This is the step-by-step process of addressable RGB LED strips:
- Turn on the power, when the current flows to the 3 LEDs on the light bar, the light will slowly turn on under the default settings
- In order to create a color effect, you must provide input commands to address the individual LEDs you want to control
- Now, the controller transmits the signal to the integrated circuit chip on the LED
- Then the IC either executes the command immediately or stores the same command for timing execution
3.The advantages of addressable LED Strip:
Compared with traditional lighting fixtures, addressable LED Strip have the following advantages:
The addressable LED strip uses low-voltage DC 5V,12V power supply voltage, so it is very safe to use. The elderly and children can use it with confidence, and there is no safety hazard.
2) Environmental protection:
No matter whether it is LED or FPC, the raw materials of the LED pixel strip are selected environmentally friendly materials, it can be recycled and will not cause environmental pollution and damage due to large-scale use.
3) Super energy-saving:
The power of the DC12V 30LEDs/m 5050 strip lights is 7.2W per meter. Compared with traditional lighting decoration lights, the addressable LED strip has much lower power and better effect.
4) Pure color:
The LED pixel tape uses high-brightness patch LED as the light-emitting element, so it has the advantages of LED light-emitting element, the light color is pure, soft, and no glare. It can not only be used for decoration, but also can be used for lighting.
5) Low calorific value:
The light-emitting of the LED strip element is LED. The power of a single LED chip is very low, generally 0.04-0.08W, so the heat generation is not high. Not only can it be used as decoration lighting in the fish tank, but it will not generate a large amount of heat to increase the water temperature and affect the growth of ornamental fish.
6) Long lifespan:
The normal operating life of the addressable LED strip is 80,000 to 100,000 hours. With continuous operation 24 hours a day, its lifespan is almost 10 years. Therefore, the life span of the LED pixel strips is several times that of traditional lamps.
The LED pixel strip uses a very soft FPC as the substrate, which can be bent arbitrarily without breaking, is easy to shape, and is suitable for various advertising modeling needs, it can be arranged arbitrarily according to space layout requirements.
8) Easy installation:
The stip led lights is very easy to install. It can be installed on various supporting surfaces with fixing clips, wire grooves, iron wires, iron nets, etc. In addition, due to the light and thin led strips, the use of double-sided tape can also achieve a fixed function. It can be installed without professionals, and can truly enjoy the fun of DIY decoration.
Waterproof led lights is divided into several grades, IP20 is not waterproof, IP65 surface glue, IP67 silicone casing waterproof, IP68 casing waterproof. Different application environments can use different waterproof levels.
In recent years, scientists have discovered that in addition to emitting visible light to provide a bright light environment, different wavelengths of light can cause damage to the skin and eyes of the human body. In addition, light can also regulate the secretion of melatonin from the pineal gland through the third type of sensory cells (ipRGC), thereby adjusting the body’s circadian rhythm. Therefore, it is of great practical significance to advocate health, emphasize the biological safety of light, and improve the quality and comfort of light. L-band luminescence, not only can meet the rooting, sprouting, flowering, and fruiting of various plants, but it will not cause harm to the human body.
Because of its softness, frivolity, pure color, etc., addressable LED strip are widely used in building outlines, steps, booths, bridges, hotels, KTV decoration lighting, and advertising sign production, various large-scale animation, calligraphy and painting advertising design. With the gradual maturity of the Addressable LED strip technology, its application scale will become more extensive.
