What is the function of fill light?

Fill light lamp is a kind of lamp used to compensate some equipment or plants for lack of light. At present, there are usually three kinds of fill light, one is camera greenhouse fill light (also called plant fill light), photography fill light (also called camera fill light) and license plate fill light (also called white light).

1. What is an LED monitoring fill light?

1.The main function of LED monitoring fill light lamp is to improve the quality of monitoring imaging picture and make the monitoring picture clear in case of insufficient light. It is the key equipment for video surveillance equipment to capture high-definition images and videos, and plays an indispensable role in the front-end information collection of intelligent transportation and security monitoring. Under normal circumstances, in places where electronic police are installed, such as bayonets, intersections, highways, etc., fill lights with snapshot function are needed. At this time, the strobe fill light and flash can synchronize the exposure and snapshot of the electronic police and effectively identify the vehicle license plate and face. In toll stations, residential areas, urban entrances and exits and other places, generally only the normally-lit fill light and infrared fill light with ordinary functions are needed. The normally bright fill light is controlled by the built-in photosensitive light source, which can be turned on and off according to the surrounding environment, and automatically turned on when the illumination is low; The infrared fill light is mainly used with a black-and-white camera, and the imaging is black and white.

Step 2 classify

1) The fill light used in the traffic field is usually used in conjunction with the monitoring camera, and the light source is led lamp beads, which has the characteristics of long service life, low energy consumption, high efficiency and energy saving. Due to different requirements, it can be divided into three types: snapshot function, simple fill light and infrared fill light; Generally, those who have the function of capturing pictures are used with electronic police, which are called strong spots or flash lamps, while those who do not need the function of capturing pictures are always-on fill light and infrared fill light.

2) Generally speaking, fill light can be divided into four types: constant light fill light, strobe light fill light, flash light and infrared light fill light.

Second, what are the functions and characteristics of LED monitoring fill light?

1. In the absence of ambient light, LED monitoring fill light can help the camera system to take clear license plate images. Snapshot or video fill light can be taken according to the actual situation.

2. The monitoring LED fill light can be used fixedly. The LED monitor fill light also has the characteristics of overlapping use of sunlight during the day and independent and compatible use of license plate lighting at night, which can suppress the backlight during the day and the glare of headlights at night. So that the camera has a good wide dynamic range.

3. The projection angle of the monitoring LED fill light lamp is unidirectional, with little light pollution, little stimulation to human eyes and no influence on driving safety.

4. Monitor the uniform light spot of LED fill light, and the luminous intensity and angle can be adjusted. The monitoring LED fill light lamp is easy to install and debug, and can be matched with various CCD cameras.

5. The LED monitoring fill light lamp has low power consumption and high efficiency. The LED monitoring fill light can be always on day and night, with long service life, and the service life of LED light source can reach 50,000 hours.

6. The invention has the advantages of low power consumption, light weight, small volume and convenient installation, and can easily form a bayonet integrated device with the camera and the protective cover.

7. The bayonet monitoring LED fill light lamp has an adjustable light switch, which can be set to turn on the fill light lamp under different illumination.
