What are the sensing methods of sensor ceiling lamps? What scenes are the sensor flush mount suitable for?

Sensor Indoor Ceiling Light are common in daily life, whether in homes, office areas, buildings or public places. Because the sensor Flush Mount can be automatically started without using a switch, it is very convenient to use, so it is very popular with people. So, what are the sensing methods of induction Lamps and Lanterns? What scenarios are sensor lights suitable for? Let's explain it to you in detail.

What are the sensing methods of induction lamps?

a) Light sensor switches

Light sensor switches are often used in some places that need automatic lighting at night, such as courtyard door front lights, street lights on urban roads, etc. It is mainly through a photoresistor (its resistance value can be changed according to the light intensity); When the light shining on the photoresistor is strong, its resistance value will become lower, the back-end circuit does not work, and the lamp will not light up; When the light shining on the photoresistor is weak, its resistance value becomes high, and the back-end circuit works to make the lamp light up. Its disadvantage is that when it is in a dark environment, the switch will continue to turn on, the light will always be on, can not achieve precise control, and the energy-saving effect is not ideal; It is easy to affect the effectiveness of its use due to dust or obstacles.

B) Human sensor switch

The human sensor switch is a further improvement on the basis of voice control, which can realize the light action in a silent situation. It is mainly composed of a pyroelectric sensor, a Garfinier lens, and peripheral control circuitry. Its working principle is that pyroelectric sensors can sense the thermal radiation released by the human body's temperature, and Finier lenses can collect and focus the human body to release infrared rays. When someone appears in the sensing range, the Finier lens focuses the infrared radiation released by the human body heat to the pyroelectric sensor, and then the pyroelectric sensor outputs a control model to the rear circuit to realize the light on and off control.

Microwave sensing (also known as radar sensing) is much more perfect than the previous control methods, and is now widely used in underground garages, road lights and other places. It uses a radar-like working principle to detect moving objects by emitting microwaves, which in turn generates the corresponding switching operation. It has strong anti-radio frequency interference ability, is not affected by temperature, humidity, light, airflow, dust, etc., and can be installed in a certain thickness of non-metallic shell, without exposure. While realizing the induction function, it can also maintain the overall coordination and beauty of the appearance (microwave sensing lamps can be exactly the same as ordinary lamps).

d) Voice-activated switch

Voice-activated switch is also an early application of an automatic control method, usually used in corridors, aisles, passageways and other places, it effectively avoids the influence of dust and obstacles on its use effect. Its working principle is also very simple, through the microphone to collect the sound signal, and then through the back-end circuit is processed to control the switch on and off, to achieve the light on and off. Usually we also add a delay circuit on the basis of the voice-activated switch to realize that the voice sounds, the light is on, and after a short period of time, the light automatically turns off.

What scenes are the sensor ceiling lights suitable for?

Traditional sensing lights are installed in the corridor, which is generally composed of two parts. One is the human body sensor panel switch, the other is the light source, and most of the light source are incandescent lamps. The two parts are separated, and during the design of the house, it is necessary to lay out the wire lines and their locations. The tungsten wire in the incandescent lamp cannot withstand frequent switching, so the broken lights must be replaced every year. Also the cost of manual maintenance is too high. LED human body sensor lamp built-in light source and body sensing device, only need to install it screwed into the general E27 lamp holder to achieve the human body sensor lamp. When people come the light on, when people go the light off. When installed, it is placed at the corner of the upper and lower stairwells, and the people going upstairs and downstairs can be sensed. In addition, the LED light source has a long life and low voltage work. Frequent switching has no effect on it.

2. Balcony

The balcony belongs to semi-outdoor, turn on the light at night, mosquitoes and flyworms will turn around the lights. And in normal life, sometimes you don't remember to turn off the balcony light. If install the sensor LED ceiling light in this position, these two problems can be solved. LED is a cold light source, does not contain ultraviolet rays, will not attract mosquitoes. Intelligent sensing of the human body, the light is always on during the activities of the balcony, and the light goes off after the person leaves, saving power and convenient.

3. Passageway

Install the sensor lights in the public passageway is also very suitable, whenever someone enters the corridor, the sensor light is on. In the delay of 1 minute, people have enough time to open their door into the house or walk through the corridor. Compared to the constant light in this position, this is much more power saving.

4. Utility room
The utility room is a messy place, the room is usually small and dark. When go in, it can`t be easy find where the switch is. When come out and have to put down the things in your hand to turn off the light, so troublesome. Then you can install the sensor lights to solve it, install it on the top of the room. When the door is opened and enter, the light will automatically turn on. The light is always on when rummaging through the items, take what you are looking for and go directly, don't worry about no one turning off the light, 60 seconds later you look back and see that it has automatically turned off.
