LED dimmer 12v is a low voltage controller for 12VDC LED lights such as LED strip lights. It features high safety and reliability compared to an AC dimmer.
To dim your low voltage LED lamps with LED dimmer 12v, you have to prepare some devices. Firstly you need a receiver that receives control signal and coverts the signal to PWM signal to control the connected lamps. Since the receiver is with 12VDC input, an AC-DC power supply is required for it. Secondly, a control unit that sends signal to the receiver shall be necessary, it may have built-in battery or AC input directly, otherwise a power supply is required.
A variety of control units are available with different kinds of control signal such as RF (Radio Frequency), DMX, 0-10V etc, it depends on your preference, and accordingly the receiver will be designed with corresponding built-in RF module, DMX module and 0-10V module that receives the signals from the control units. The receiver will firstly receive the signal, then convert the signal to PWM dimming signal that can dim the connected lights.
The advantages of RF signal is that it can control wirelessly, which means the control unit can be remote which does not have to be wired with the dimmer. The DMX and 0-10V signal both need wiring which means the control units shall be wired to the dimmer. Using an RF type LED dimmer 12v enables flexible and convenient control to a low voltage LED lamp. The control units can be available in many different designs such as handheld remote, wall mounted full touch, rotary knob and push button. All these can offer smooth dimming and switch functions. Handheld remote and wall mounted full touch are highly recommended since they are the latest popular trends.
The dimmer is designed with 12VDC constant voltage input and output, so you have to wire it with a CV LED lamp like LED strip light. Designed with 4 channel output, the dimmer can control single color LED strip, dual white LED strip, RGB/RGB+W LED strip while working with corresponding control units. For single color, it offers dimming and switching functions; For dual white colors, smooth color temperature adjustment, brightness adjustment and switching are all available; For RGB/RGB+W colors, it can offer smooth RGB color tone adjustment plus brightness adjustment and switching of each R, G, B, W channel. It can create really cool dynamic color changing patterns for RGB colors.
If you would like a constant current LED dimmer, it is also available in the market. As similar as constant voltage one, you have to figure out the situation first then to choose right dimmer.
3D Moon Lamp for Creating Right Atmospheres
Lighting is a very important aspect for creating right atmospheres for dating, parties and holidays. Compared to traditional lighting design, 3D Moon Lamp is a more flexible and portable LED moon lamp that adopts LED light source and is powered by rechargeable battery.
FDM 3D Printer Widely Used for Prototyping and Concept Model Building
Fused Deposition Modeling builds concept models, functional prototypes and end-use parts in standard, engineering-grade and high-performance thermoplastics. It’s the only professional 3D printing technology that uses production-grade thermoplastics, so parts are unrivaled in mechanical, thermal and chemical strength.
DLP 3D Printer To Print High Precision Objects With Ultra Smooth Surface
DLP stands for digital light processing that is one of the popular technologies used for 3D printing. Unlike FDM technology, this technology uses light from projectors to turn liquid resin into a solid object, one layer at a time and accumulates layer by layer finally to form an object.
