DL.3 mounts like any other intelligent moving luminaire and controls just as easily with plug-and-play operation using standard DMX cabling and protocols. Production set-up time is reduced as there is no need for RGB cabling, and racks of servers are no longer necessary at front-of-house or backstage area. A Content Management Application running on your MAC or PC workstation or laptop computer gives you remote control of uploading and crossloading content, upgrading software and fixture configuration for multiple DL.3 fixtures on a fixture network. Collage Generator™This patent-pending feature enables multiple DL.2 and DL.3 units to create seamless vertical, horizontal or central panoramic media projections controlled from a lighting console. Using multiple digital lighting fixtures allow you to increase effective screen luminance. High End Systems not only started the digital revolution, it also offers the widest digital lighting product mix of any manufacturer, priced and scaled for any budget and solution. The DL.3 represents the fourth generation of digital lighting products from High End Systems Inc. and is the flag ship addition to the product line, which includes the Orbital Head, Axon Media Server and DL.2 digital light.

We often experience the power of nature. One of the most fearsome natural phenomena is lightning. Some people might be curious why and how it occurs. Today, we know that lightning is a flow of electricity. In this chapter we are going to study about characteristics of electricity.

| Section 1. Net Electrical Charge | |||
![]() | Matters are made of atoms. An atom is basically composed of three different components -- electrons, protons, and neutrons. An electron can be removed easily from an atom. |
Normally, an atom is electrically neutral, which means that there are equal numbers of protons and electrons. Positive charge of protons is balanced by negative charge of electrons. It has no net electrical charge. When atoms gain or lose electrons, they are called "ions."
|
| ![]() | What is charge? Objects that exert electric forces are said to have charge. Charge is the source of electrical force. There are two kinds of electrical charges, positive and negative. Same charges (+ and +, or - and -) repel and opposite charges (+ and -) attract each other. |
The law of consevation of charge says that charge is neither created nor destroyed. This state ment brings us new question. What do you think about this statement? |
| Section 2. Conductors and Insulators | ||
| Substances can be classified into three types -- insulators, conductors, and semiconductors.Insulators are materials which allow very little electrical charges and heat energy to flow. Plastics, glass, dry air and wood are examples of insulators. Conductors are materials which electrical charges and heat energy can be transmitted very easily. Almost all metals such as gold, silver, copper, iron, and lead are good conductors. Semiconductors are materials which allow the electrical charges to flow better than insulators, but less than conductors. Examples are silicon and germanium. |
|
| Section 3. Charged Objects |
![]() | |
When two objects are rubbed together, some electrons from one object move to another object. For example, when a plastic bar is rubbed with fur, electrons will move from the fur to the plastic stick. Therefore, plastic bar will be negatively charged and the fur will be positively charged. |
a. Methods of Charging |
![]() (Electroscope) | When you bring a negatively charged object close to another object, electrons in the second object will be repelled from the first object. Therefore, that end will have a negative charge. This process is called charging by induction. |
When a negatively charged object touches a neutral body, electrons will spread on both objects and make both objects negatively charged. This process is called charging by conduction. The other case, positively charged object touching the neutral body, is just the same in principle. | ![]() (Electroscope) |
How does lightning start and end? |
| Section 4. Unit of Electrical Charge: The Coulomb " C " | ||
| The symbol for electric charge is written q, -q or Q. The unit of electric charge is coulomb "C". The charge of one electron is equal to the charge of one proton, which is 1.6 * 10-19C. This number is given a symbol "e". |
|
| Section 5. Coulomb's Law | ||||
| The magnitude of force that a particle exerts on another particle is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
F is the force between the two particles, q1 is the net charge on particle A, q2 is the net charge on particle B, d is the distance between the particles, k is a proportionality constant which is 9.0 * 109 Nm2/C2. The direction of the force is on the line from one particle to the other. |

Of all the electromagnetic waves, light is the only portion of waves that can be detected by the human eye.
|
![]() | Section 1. Luminous and illuminated bodies. | |
![]() | Light is produced by a luminous body. A light bulb is a luminous body that emits light in almost every direction.Light travels in straight lines at 299,792,458 m per sec in vacuum. When light hits an object, it is reflected. An illuminated body reflects light. When a ray of light reaches our eyes, the receptors in our eyes will produce a different color sensation depending on the wavelength of the light wave. |
![]() | Section 2. Luminous flux and illuminance. | |
![]() | The amount of light produced per unit of time is called the luminous flux, P. The unit for this is the lumen, lm.If we only want to know the amount of light produced by a source on a specific object (table, chair), we have to use the formula for illuminance, E. This formula tells us the amount of light per meter square at a certain distance. E = P/4(pi)d² Thus, the illuminance is just the luminous flux divided by the area of a sphere. Why a sphere? For example, lets put two objects in different places, both of them two meters away from a source of light. ![]() As you can see the illuminance on these objects is the same. This is because almost every source of light emits light in all directions and two objects within the same radius receive the same amount of light. However, objects that are placed at different distances have different illuminations. ![]() The closer an object is to a source of light, the more illuminated it will be. |
![]() | Section 3. ColorsRed, green and blue are known as primary colors, because when they are added together white light is formed.![]() By mixing primary colors in pairs we obtain secondary colors. Red and green produce yellow. Blue and red produce magenta, and blue and green produce cyan. |
![]() | Section 4. Reflection of light | |
If we draw a line perpendicular to a surface, this line is the normal of the surface. When a ray of light hits the surface of an object, part of the light is reflected. If the ray of light is in angle with the surface, then the angle between the incident ray and the normal will be the same angle between the normal and the reflected ray.![]() They are not completely flat surfaces. When millions of rays of light hit the rough surface of an object, they are reflected in all directions. This is how we can see illuminated objects. How does a mirror reflect light? |
![]() | Section 5. Refraction of light | |||
When a ray of light passes from one medium to another, it bends. Depending of the new medium the light will travel faster or slower. If the light travels faster in the second medium, then this medium is called the rarer medium. On the other hand, the medium in which the light travels slower, in this case the first one, is called the denser medium.
|
![]() | There is an index of refraction (n) between the two mediums. To get a value, we have to divide the sine of the angle in vacuum or air by the sine of the angle in the denser medium.In the example above, the index of refraction would be n = sin a / sin b |
![]() | Some of the light is always reflected. However, when a ray of light goes from a denser medium to a rarer medium, all the light will be reflected if the angle of incidence is greater than the critical angle. The critical angle is the angle of incidence for which the refracted ray is at 90 degrees with the normal.![]() How do lenses refract light? |
