At present, the types of remote controllers used for lamp control mainly include: infrared remote controller and radio remote controller
● Composition and principle:
The signal is sent by the oscillator, and then driven by power. The transmitting element (piezoelectric ceramic, infrared transmitting diode, or radio wave) emits infrared or radio wave. The receiving element on the lamp receives the signal to adjust
1. Infrared remote control: it refers to a kind of infrared remote control with a wavelength of 0.76 ~ 1.5 μ M to transmit control signals.
2. Radio remote control: It refers to a remote control device that uses radio signals to control various mechanisms in the distance. When these signals sent by the remote controller are received by the remote receiving equipment, it will command or drive other corresponding mechanical or electronic equipment to complete various operations.
● Distinction
Infrared remote control
Infrared remote control uses infrared to transmit control signals. Its characteristics are directional, unable to pass through obstacles or remotely control the equipment from a large angle. The stable distance is generally no more than 7 meters and is not subject to electromagnetic interference. The anti-interference ability is not very good when the distance is far. The TV remote control is infrared remote control.
Radio remote control
Radio remote control uses radio waves to transmit control signals. At present, 2.4GHz wireless remote control is commonly used. Its transmission mode can effectively solve the disadvantages of infrared remote control and enable you to remotely control the equipment from all angles in the house. And it is a 360 degree operation without dead angle. The omni-directional three-dimensional coverage is the advantage of the 2.4G remote control, and it is also the best type of remote control at present. Disadvantages: the cost is high. For the same 11-key remote controller, the production cost of 2.4G remote controller is twice that of infrared remote controller. Therefore, this kind of remote control is usually used in the high-quality market.
● Application of remote controller on lamps
1. On / off control
It is directly used as a switch to control the input on-off of the lamp to make the lamp on or off, and can also control the on-off time.
2. Brightness, that is, the control of light intensity,
There are two main methods to control brightness: one is mechanical addition and subtraction method, that is, to increase or decrease the total luminous intensity by controlling the number of lighting lamps; Another method is the electrical control method, that is to use various dimmers to change the working voltage or current of the lamp, so as to adjust the luminous intensity of the lamp. According to the dimming methods, they are divided into: rheostat dimming, autotransformer regulator dimming, saturation choke dimming, magnetic amplifier dimming and thyristor dimming. The first four dimming devices have the disadvantages of large volume and bulkiness. At present, thyristor dimmer is widely used
3. Color control
It is mainly to adjust the brightness of RGB three colors or the individul luminous intensity of RGB three colors to adjust the color.
4. Control of sensing distance
The sensing head on the lamp will set a standard sensing range, and several gears within this range will be given on the remote control. The transmitting device on the remote control encodes the key information through digital coding technology, and transmits light waves through infrared diodes. The infrared receiver of the light wave receiver converts the received infrared signal into an electrical signal, which is decoded by the processor and demodulated into the corresponding distance range instruction
At present, in addition to some environmental protection standards, the remote controller equipped with lamps produced by Wellway has no mandatory reference standards for product functions. It is determined whether it meets the requirements according to the standards agreed between customers and manufacturers or the factory standards according to the user's experience.
All kinds of lamps produced by Wellway can be equipped with remote control signal receiver, and the remote control can be used to realize the control function. It can be superimposed with brightness, object movement and other control signal sources to realize multiple control functions.
