Relay switch is the most basic light control mode, which corresponds to the electrical switch module. This module can control the switches of four light circuits. You can simply understand it as that four switches originally installed on the wall are collectively installed in this module. Therefore, when wiring, you only need to pull the power line of the controlled circuit to this module to achieve switch control, just like this, on and off.
This is also the most mainstream control mode in the current light control market. It is really hard to imagine. Dimming technology has been invented for more than 100 years. We have all been in an era of artificial intelligence virtual reality technology, which is ready to come out. However, the most important control mode for light is still such a simple and crude way of opening and closing. Of course, the future must be the era of dimming, Just like music becomes beautiful because of its cadence, light and shadow also need to change in light and shade to become vivid. Friends who like painting or photography may be sensitive to this, but even ordinary people can never go back once they experience good light adjustment.
Back to the relay switch module, it makes a very loud sound every time it is switched on and off. Like this, the sound of the Luchuang relay switch is actually low. I heard some relay switches of KNX system in some reconstruction projects. If more than five circuits are switched on at the same time in a scene, the sound is like setting off small firecrackers, Therefore, if you have a friend with neurological decline, you must be careful to select the relay switch module. If you have to use it, you must put the light box far away. Some friends like to hide the light box in the bedroom wardrobe. This must be a wrong practice. Regardless of the security problem, the customer experience is very poor with this sound alone.
The most common dimming method, tangent phase dimming, is actually in two forms, one is front edge tangent phase dimming, the other is back edge tangent phase dimming. The principle of dimming is the same. Front edge tangent phase is the first half of the tangent sine wave, and back edge tangent phase is the second half of the tangent. In actual use, the difference needs to be noted is the matching between the front end dimming module and the rear end dimming power supply, that is, the stuff behind the lamp, But don't worry too much. The possibility of your wrong choice is also very small, because the combination of silicon controlled dimming power supply and cutting-edge tangent phase dimming module is the mainstream of the dimming market, and the market share along the tangent phase is almost negligible,
In addition, phase-shift dimming is the same as the circuit controlled by relay switch in terms of wiring mode. It only requires that your lamps match the dimming system. Therefore, compared with other dimming methods, it will be slightly more acceptable, but it is still difficult to popularize in the home market.
The problem is still the price. Like Lucheng's tangent phase dimming module, it may be the best tangent phase dimming module on the market in terms of stability and dimming effect. But when it comes to the price, a little ordinary local tyrants have to say that they are bothered, because the price of such a four circuit dimming module is about 7000 or 8000 yuan, equivalent to the price of an iPhone X, an ordinary three storey villa, The lighting circuit is generally more than 100 circuits. If you use this phase cut method to do the whole house dimming, the price of a single module is more than 200000 yuan, not including the control panel. Obviously, few people can afford it.
