Human demands for home comfort are growing, and with them the number of appliances that make everyday life easier is increasing. A motion sensor lamp is one such device. Its main function is to turn on the lighting when it is needed, and automatically turn it off. No more looking for keys or a switch in the dark, no more watching for energy overruns.
Especially convenient LED lamps with a battery-powered motion sensor. They are compact, do not require electrical wiring, economical and durable. Photos of LED lamps with a battery-powered motion sensor, the most popular models are presented below. In the article we will talk about the design features, advantages, disadvantages, as well as areas of use for lamps withmotion sensor.
Application areas
In everyday life, lamps with a motion sensor are used for both indoor and outdoor lighting. They have proven themselves as the main lighting in hallways and bathrooms. LED lamps give bright enough light to perform the necessary procedures and are not afraid of moisture. Lamps with a motion sensor are indispensable in homes where there are small children who cannot turn on the light themselves. The light will turn on and off automatically when the room is empty.
Small size LED rechargeable luminaires are great for illuminating stairs and corridors. Placed at the bottom of the wall, they not only illuminate the steps, but also look spectacular. Light Angel battery powered motion sensor LED spotlights are suitable for illuminating the work area in the kitchen and pantry. Compact size, lamp swivel mechanism and convenient mounting allow you to install it on both horizontal and vertical surfaces.
Furniture LED lamps with a battery-powered motion sensor are very convenient for illuminating the interior of cabinets and dressing rooms. They greatly facilitate the search for the right thing, do not heat up and can be attached in any convenient place. Devices in the form of LED strip can be used as a night light if you attach them under furniture. They create a soft, diffused light that doesn't irritate the eyes, but is bright enough to avoid tripping at night.
As outdoor lighting LEDbattery-powered motion sensor lamps are used in the front door area, along driveways and garden paths. In addition to their direct purpose, lighting, such lamps will warn about welcome and unwanted guests, as well as scare off intruders.
Benefits
The main advantage of LED lamps with a battery-powered motion sensor is their autonomy. They do not require pulling wires, so such a lamp can be installed absolutely anywhere. With a high intensity of the luminous flux, such lamps are light and compact. They are very economical due to the use of LEDs in the design. The latter consume 5-7 times less energy than incandescent lamps, and their service life is about 100 thousand hours. Thanks to this, the battery-powered motion sensor LED lamp will last for a long time.
Additional energy savings are created thanks to the motion sensor. The lamp burns only for the necessary period of time, which saves up to 30% of energy compared to conventional lighting. Devices designed for outdoor lighting and bathrooms have a sealed housing that protects them from moisture and dust, thereby also extending the life of the device. Battery powered motion sensor LED furniture light suitable for installation in limited cabinet space. It does not heat up, does not emit harmful substances and does not emit ultraviolet radiation. The lamps are easy to use and maintain. It is only required to periodically wipe them from dust with a dry cloth and change the batteries.
Flaws
The most serious drawback of such fixtures is motion sensor failures. They are usually caused by incorrect sensitivity and range settings. The sensor can be triggered by heating devices, pets, movement behind thin doors or windows. Rechargeable lamps require periodic replacement of batteries or their recharging. Sealed models designed for street lighting or bathrooms are almost impossible to repair in the event of a breakdown. The design of such lamps is quite simple, but it will be problematic to restore the tightness of the case. Moisture and dust that gets inside the device will quickly disable it.
Working principle
Motion sensing lights consist of LED, motion sensor, photocell, battery and case. The design, as well as the number of LEDs, can be different. Some devices have a regulator of the intensity of the luminous flux and the color shade of the light. Such devices can be used as a night light. The motion sensor captures the temperature or wave fluctuations of the surrounding space, when an object is detected, the circuit closes and the light turns on. The angle and range of object recognition is adjustable. The photocell is designed to measure the level of illumination. With sufficient natural or artificial light, the lamp does not light up.
Use AA or AAA batteries as the battery. Some models can be charged via USB ornetworks, they use rechargeable batteries. The charging cable is usually included. The body design is quite varied. There are models in the form of a tape, linear, rotary, classic square and round. Night lights with a motion sensor often have an original design. Compactness and low weight allow you to mount lamps with double-sided adhesive tape. Rechargeable models often have a magnetic strip for easy removal. The magnet is attached to the surface with adhesive tape or screws, and the lamp itself is held by the force of the magnetic field.
Types of sensors
In household models, three types of motion sensors are used:
- Microwave. The device emits high-frequency electromagnetic waves. It is highly sensitive and can recognize an object behind thin barriers. Sometimes erroneously triggered by movement outside a door or window. Due to the fact that electromagnetic radiation is dangerous to humans, such devices are rarely used in residential areas.
- Ultrasonic. The sensor picks up changes in reflected ultrasonic waves. He recognizes the object even in warm winter clothes in a very dusty room. However, if a person enters quietly, the device may not work. Ultrasound is completely harmless to humans, but animals are sensitive to it and can behave restlessly. Such devices are suitable for installation in spacious rooms, on stairs, in the entrance, for street lighting.
- Infrared. This is the most popular type of sensor in household fixtures. It reacts to changes in room temperature and is completely harmless to humans and pets. The lamp with an infrared sensor is suitable for small rooms, pantries, dressing rooms, cabinets. The sensor may erroneously react to heaters and pets. If the person is wearing thick clothing that does not allow heat to pass through, the device may not work.
- Universal. Such devices combine several principles of recognition, which increases their efficiency and reduces the risk of errors.
Types of fixtures
Lamps with a motion sensor can be divided into 2 large groups: for outdoor and indoor lighting. The former are distinguished by a high degree of weather protection.
Depending on the design features, lighting fixtures with motion sensor can be divided into pendant, ceiling, wall and table.
Care and maintenance
Caring for the device is quite simple, you should periodically clean it from dust and change the batteries. In order for the luminaire to last longer, it is important to prevent overloads that occur due to incorrect setting of the detection distance and angle, as well as to remove foreign objects from the device’s range: hanging furniture, curtains, indoor plants.
Reviews
Reviews of battery powered LED lamps are mostly positive. However, some users report erroneous detections of the sensor during the daytime and on pets. Household models with an infrared sensor poorly recognize a person in outerwear.
Battery lamps with a motion sensor are an indispensable thing when lighting hard-to-reach places where there is no way to conduct electrical wiring. They are compact, economical and safe. In household models of lamps for indoor lighting, an infrared motion sensor is most often used. Outdoor luminaires have a high degree of protection against dust and moisture and an ultrasonic sensor. Battery-powered lamps are used for general lighting and illumination of corridors, hallways, stairs, bathrooms, dressing rooms and furniture.
