luminous flux luminous flux of light from a light source is expressed in the song and is measured

The light source is equal to the amount of light emitted in all directions does not factor in any specific direction Candela power, defines the amount of light in that direction. runway lights In fact, we can say that the intensity or brightness of the light in a certain direction runway lights will be determined by Kndla.
Dimmer (Illuminance) 1- The luminosity flux density on the surface, or by Footcandle unit luxury (Lux at Vahdmtryk) is measured. Illuminance is the most common form of property. 2-Illuminance is to measure the brightness of the surface runway lights properties of the flux appears, is. Illuminance by fixing the light intensity of the light source and the distance between the surface and the angle of intersection of the light hitting the surface. However, the intensity is a factor that can not be measured with the optical design is the most common criterion. Lumen Lumen)) Rabbi basic unit of measurement of light. A candlelight dinner for about 12 lumens and a 60-watt bulb with more power at about 855 lumens runway lights white light makes Sat. If a point source of light in the center of a sphere of radius a Kndla feet about a foot square opening in the surface, similar to that of a lumen LED light is Sat. Light intensity, lumen flux angle of the light passing through the atmosphere (Steradian) is the light intensity measured in candela. Solid angle, the angle at which the center of a sphere's surface can be seen. Solid angle is equal to the ratio of the square of the radius of the sphere. The light intensity at each point in space, independent of distance and proximity to the light source to an extent, but in a different direction than it is different. Lumen: The amount of visible light from a light source or the luminous flux received from any angle Astardyan the outside.
Radiation (Luminance) luminance intensity (brightness Fvtvmtryk) Each level in a specified direction for a specific unit of the surface can be seen in the same direction, the unit Candela / m ^ 2 is measured. Luminosity flux (Luminous flux) of all the light produced by the light source. runway lights In fact, the amount of light that the object regardless of its leaves. A typical 100-watt incandescent bulb, about 1,700 lumens and a high-pressure sodium vapor lamps up to 400 watts of light emits 50,000 lumens. The brightness of the lamp flux rate that is offered runway lights by companies and ordinary lamp lumen value list can be found at the Lamp Matrix.
luminance intensity (Candelas) luminance intensity along the optical intensity is emitted in a specific runway lights direction. The intensity of a light shining in a particular graphical representations called Candela power curve changes runway lights Kndla or characterized. The polar diagrams runway lights Cartesian illusion of light industry are used for this purpose. This information is available on the digital runway lights charts.
Lux light intensity Illuminance measurement unit in the metric system. And in the light of the planar square meters where the light flux of one lumen uniformly shine on it. The deluxe 76/10 Foot candle is equal to one. One lux is equal to 09/0 Foot candle. runway lights And ten luxurious Deluxe is a 1-76 / 10 lux = 1 Foot candle 2- 1 lux = 09/0 Foot candle 3- 1 = 10 luxurious Deluxe surface density flux emitted light intensity to a level that is called by Luxury measured. Intensity for different applications, the recommended client. These suggestions are based on the complexity runway lights of the work that must be done carefully, offered. For example, for simple tasks like walking in the corridor of 120 lux illumination required in the case of very small things like assembly machines and tools are great of human vision., The brightness up lux is required in 1000. Luxury unit of light intensity in lux light show and a luxury unit flow generated from a uniform runway lights light a candle at a square meter. Intensity in some places familiar street level 100 luxurious rooms and 30 luxurious living room of 300 lux work surface in the winter sun in the summer runway lights sun surface of 10,000 lux to 100,000 lux
luminous flux luminous flux of light from a light source is expressed in the song and is measured in lumens. runway lights If a point source of light, the intensity of one candela, placed at the center of a sphere of radius of one meter, with a surface area of one square meter in the world, the light flux of one lumen will receive. The more lumens per watt light source generated by a higher input power is more efficient light source.
The light intensity distribution curve of light distribution in polar coordinates, the light intensity of a lamp or the light of the screen shows a lamp or light passes exactly through runway lights the center. runway lights The intensity of light at different angles around a lamp on the table. Since in many cases, the light intensity distribution is symmetric around a lamp, light intensity curves are plotted for different pages. runway lights Normally the top three are: the plane normal to the axis of the tube, plate parallel to the axis of the tube and plate with a 45 angle relative to the axis of the tube. After selection of pages, each page can be made light intensity curve. Combination lamps and light bulbs and each one has its own unique curve. Curve of the light intensity of the lamp, lamp and ballast depends on the type of coverage.
Luminance: the relative intensity of the light source (or light reflective object) to the area of stranding source (or the area of the portion of the object runway lights that reflects light), the smaller the surface area is bright, runway lights its brightness is higher. runway lights Luminance is candela per square meter (Astilbe) or candela per square runway lights centimeter (intentions) are measured. Brightness for the human eye
