As explained in the previous meeting (on the subject of the types of street lighting armature) that k omponen armature lights (luminaires) can be grouped according to function and consists of:
Well, at this meeting will be described on the first optical system armature lights (luminaire) street lighting. While the electrical system and mechanical system of street lighting armature vanity mirror will be described in subsequent meetings.
An armature lamp optical system (luminaire) consists of a lamp, reflector and refractor. Each of these components will be described as follows: The most important component of the system is pencahayaaan light source. This component is a major determinant of aspects of visual quality, economy, efficiency, and energy conservation aspects of the lighting system. A source vanity mirror of electrical caahaya a device that converts electrical energy, or electrical power (in watts) into electromagnetic radiation or light appears (in lumens). The rate of change of electrical energy into visible vanity mirror light is called "light-effectiveness" is measured in lumens per watt. Figure 2 below shows the "family tree" or family tree of lights.
Only high intensity light diffusing (HID) which is currently used for street lighting projects. vanity mirror While the general characteristics of other street lighting as shown in the table below.
95 -140
Variations street lighting has been used for many years. A description of the types of light and handy hints on its use will be described as below. vanity mirror
- Requires ballast (resistor current transformer).
- Substitute the popularity of incandescent bulbs. Higher initial costs and require ballasts, but thanks to the relatively higher efficacy and longer shelf life (when introduced) vanity mirror makes it much more attractive vanity mirror than the incandescent bulbs. However, at this time it is not yet meet the standards of energy.
- The blue color - clear white lights are generally vanity mirror acceptable, and the size of the arc tubes provide a light source that is small enough to allow for better light control. A phosphor-coated outer bulb, which consists of a higher output and a more pleasant color display is also available. However, due to the light control is more important than the color of the street lighting congenital, it is usually prefer to use clear lights.
- Is a type of mercury lamp arc tube which contains, in addition to additional mercury, certain iodide vanity mirror compounds can increase the effectiveness and good color display without vanity mirror using a phosphor-coated balls.
- The size of the light source is an arc tube size, allowing better control of the light remains the same equipment as used in the mercury lamp and a clear color display is excellent, but the lower the lamp lifespan.
- Internal vanity mirror starting device operates with ballast mercury lamp or metal halide lamp ballasts.
- Dual arc tube or lamp "standby" vanity mirror to provide light as soon as power is restored after a momentary power interruption occurs, in addition, have a lifespan of over 40,000 hours.
- This type of lamp requires a special ballast and an increased amount of material in accordance with the size of the lamp power (watts), to 185 W lamps along the 3.5 feet. The large size makes it difficult to get good light control in a reasonably sized equipment.
- Bad color display and the large size of this low pressure sodium lamp makes it popular for use as highway lighting and other places besides industrial lighting or security vanity mirror applications.
- Low pressure sodium lamps are very efficient light sources to provide more light in the same amount of electricity with one type of lamp that has been described above.
Efficiency in converting light energy into electrical light, vanity mirror ability to maintain light output over the life of light bulbs, vanity mirror long life lamp life, warn

Failure kitchen designer is the beginning of success, so the sages say. Indeed, the sentence was not wrong. kitchen designer The proof is a lot of successful people are where success begins first failure. One famous story is a story of failure experienced by the inventor of the electric kitchen designer light, Thomas Edison. He is the inventor of many things, one of which the most famous is the electric light. Then how the story of the inventor of this one?
Initially, when he was a child, he said idiot by teachers at his school. He was expelled from school because it's too much to ask, and according to the teachers question does not make sense. He never asked "Why did the chicken feathered and furry not human?", "Why are humans different kitchen designer from the feather quill?", "How can a chicken kitchen designer feather on her?". His teacher was confused to give a proper answer so he did not ask again. Finally, the teachers also agreed to remove it from the school. They do not realize that the curiosity of Thomas Edison was a reflection of his genius, so the question that he hurled beyond the current age and era.
After being expelled from school, Thomas small caged by parents in the warehouse because they had to go to work. However, little Thomas is not sad, he was glad for finding many objects that can be used as toys, dismantled and reassembled it. One day, he had met with the neighbors daughter, Mary. The boy asked, "What are you doing?" and little Thomas replied, "I'm incubating chicken eggs". Mary surprised with what little Thomas did. "Do you think that you erami chicken eggs that will hatch?", Thomas answer was, "If I have not tried it, how can I know it will hatch or not?"
Teenager Thomas Edison finally back to school. Finish finish school, he had to work to make ends meet. She has worked as a paperboy kitchen designer and some strenuous manual labor. He was only established after successfully kitchen designer finding a voice recorder. He was married to Mary and living in a house that also serves as a research laboratory. However, Mary first died before Thomas was able to locate electric lights. A few years later his house burned kitchen designer down. He was then hit by a financial crisis that forced it to borrow money to rebuild homes and laboratories. He said he would find that the electric light when it is considered impossible, to convince people that he lend money.
After receiving the loan, Thomas begin his experiments to find the electric lights. Experiments invariably failed to dozens of times and even hundreds of times. But he does not consider himself a failure. He said that he had managed to find hundreds of objects that can not turn on electric lights. That said, he has done a thousand times the experiment. He was to the point of stress, confusion and panic, but never give up. And that's the thousandth experiments were successful. Electric light he found now able to illuminate the world. kitchen designer If there is no discovery that the world must not be as bright as today.
Message kitchen designer from Thomas Edison is "How many people give up when just need a few more steps to arrive at success." And one of his wise sentence, "I will definitely be successful because it has run out of a failed experiment."

Okay buddy, after we discussed about the optical system of street lighting armature, this time we laanjutkan to discuss about the electrical system style pantry and mechanical system of street lighting armature, To be able to understand, follow style pantry and refer to the following description.
Components of the electrical system on the armature lights (luminaire) street lighting are discussed in this section is the ballast. A ballast is required for all types of HID lamps and fluorescent lamps (neon). A ballast generally has three functions:
- Keeping the lights remain in operation at the beginning of the design parameters. HID bulbs have a resistance or a very low impedance operation. In addition, style pantry if there is no HID lamp ballast control operations, then the flow will continue to increase which causes the impedance also declined steadily, and resulted in increased flow continues until belebihan. The cycle will continue until the lights burning and the phenomenon is called negative resistance. Ballasts provide control functions and limit the available power to the lights.
Usually ballasts used in street lighting is a type of regulator or constant wattage. Summary of the characteristics of the type of ballast used in street lighting is presented in the following table.
Line (volts)
Ballast for high pressure sodium lamps are located in the armature lamp, the only exception if it will be used for the pedestrian style pantry area lighting ballasts can be mounted on a pole.
System mechanical armature lights (luminaire) serves to mengenas all optical and electrical components to be safe, neat and attractive. The system consists of the luminaire, lamp socket support, slipfitter, hinges and mechanical fasteners to allow ready access to the interior of the luminaire, and an assortment of miscellaneous hardware.

Type of tread base or foundation of street lighting poles, include high tapered tread base, base anchors tread, tread base shoe, and base tread standard transformer. While the basic tread material pole street lighting, among others, made of stainless steel, cast aluminum base for transformer footprint, and concrete.
Placement or installation of street lighting rust oleum poles are technical decisions should be based on geometry, highway character, physical characteristics, environment, maintenance available, economics, aesthetics, and overall lighting purposes. rust oleum The condition affects the location of street lighting pole placement including wall noise barriers, guard rail post railroad crossings, narrow side street, power lines, the nearest airport, traffic signal lights and terdekaat residential neighborhood. If space does not not allow, the pole can be placed on the back wall of noise barriers, but the access road shall be provided for maintenance. Poles must be placed at least 2 meters behind each post guard rail railway crossings or at a distance that would allow officers to keep perl.intasaan rails properly. When the street lights should be installed rust oleum and associated with traffic signal lights, rust oleum the street lighting should be installed on the same pole with the installation of traffic signal lights, if possible.
In order to support adequate illumination structure, the foundation must be designed to support the weight of the structure rust oleum as well as withstand wind loads and vibrations. Four basic types of tread standard rust oleum commonly used is the type P, E, H, and tower. The composition of the tread base of the pole corresponding to the height of the pole is as follows:

But for this meeting will only discuss about the types of armature lights (luminaires) are widely used for street lighting. As for luminaire support systems, service and selection of cabinet perelatan street lighting will be discussed at subsequent meetings. shenandoah cabinets
Armature lights (luminaire) is a complete lighting shenandoah cabinets unit consisting of a lamp along with components that are designed to distribute the light, to put and protect the lamps, and to connect the lamps to the power supply. Armature Components lights (luminaires) which will be discussed in the following paragraphs may be grouped according to function as follows:
Some factors affecting pemlihan luminaire types that will be used is the standard type luminaire must be maintained and approved by the relevant agencies such as the department of traffic and highway transportation, shenandoah cabinets traffic policeman PLN and so on. Luminaires for street lighting usually have to look in the mirror like a shallow style "cobra head" style "head-down", or stylized "high pole". However, in certain circumstances the luminaire style "shoe shenandoah cabinets box" also needs to be used. Shoebox-style luminaire is suitable for interior lighting in the rest area, where the local authorities in charge of maintaining shenandoah cabinets and caring for bulbs, light fixtures and other lighting shenandoah cabinets decorations are used. Should luminaire must have photocells that are a source of backup power when the main power source of PLN can not supply power. Some of the following images are standard luminaire types are widely used.

The types of lamps armature we have discussed in sufficient detail in previous meetings, including optical systems, electrical systems and mechanical systems of the armature penernagan street lights. Furthermore, at this meeting we will discuss about the support system armature lights (luminaire) street lighting. Okay to understand more about the support system of street lighting armature following description.
Mast arm serves to support or refute the armature lights (luminaire) on lateral dimensions pie safe of the pole. Mast arm length is usually 6 meters, pie safe 9 meters or 12 meters. Conventional lighting unit must have a pole arm sleeve type twin (telescoped into the top of the mast) or types of spines pie safe by placing the assembly. If you want to use decorative lighting pole arm another type, or if the lamp should be in accordance with the existing light poles may use different types of lengaan pole.
High mast lighting can affect intensity, brightness uniformity, coverage area, and the glare on a lighting unit. Lighting units are mounted higher provide a wider coverage area, more uniform, and reduce glare, but the level of intensity of light (footcandela) becomes lower. By using this type of high mast, mast needs fewer and poles can be set back far exceeds the length of the road. Types of high altitude pole is 30 meters, 40 meters and 49 meters. Channel power, the nearest airport and the nearest pie safe residential area may limit pole heights are used for lighting. While the pole height is not restricted, you can use the high mast tower lighting pie safe instead of conventional lighting pie safe units in locations such as the complex road junction in the center pie safe of the freeway. High mast tower lighting armature has an altitude ranging from 100 meters to 120 meters.
In general, a marker of type long sleeve containing mast pole, high nominal pole, and the pole type. Pole marker reads as follows:
- Subsequent letters before the dash indicates the type of pole used. If no letters are in that position, it means that the pole has a transformer foundation or foundation height, serves basic footprint for installation of lighting poles, and has no end or pole to pole aluminum stainless steel or galvanized steel pole.
1) 9-40.9 'high pole with a mounting pie safe arm 40', no foundation or foundation transformer high, made of aluminum or stainless steel, as shown in the plan.
