Dark Suckers

One of our customer’s had an employee write an anonymous article called Dark Suckers.  Below is the article.  This is not the opinion of this company, but we did find it entertaining and thought you might as well.  Enjoy!

 

Dark

Written by The Quantum Mechanic

For years it has been believed that electric bulbs emitted light. However recent information has proven otherwise. Electric bulbs don’t meet lights, they suck dark. Thus we call these bulbs dark suckers. The dark sucker theory proves the existence of dark, that dark has mass heavier than that of light, and that dark is faster than light. 

The basis of the dark sucker theory is that electric bulbs suck dark. Take for example, the dark suckers in the room where you are. There is much less dark right next to them than there is elsewhere. The larger the dark sucker, the greater its capacity to suck dark. Dark suckers in a parking lots have a much greater capacity than the ones in this room. As with all things, dark suckers don’t last forever. Once they are full of dark, they can no longer suck. This is proven by the black spot on a full dark sucker. A candle is a primitive dark sucker. A new candle has a white wick. You will notice that after the first use, the wick turns black, representing all of the dark which has been sucked into it. If you hold a pencil next to the wick of an operating candle, the tip will turn black because it got in the way of the dark flowing into the candle. Unfortunately, these primitive dark suckers have a very limited range. There are also portable dark suckers. The bulbs in these can’t handle all of the dark by themselves, and must be aided by a dark storage unit. When the dark storage unit is full, it must be either emptied or replaced before the portable dark sucker can operate again.

Dark has mass. When dark goes into a dark sucker, friction from this mass generates heat. Thus it is not wise to touch an operating dark sucker. Candles present a special problem, as the dark must travel into a solid wick instead of through clear glass. This generates a great amount of heat, thus it can be very dangerous to touch an operating candle. Dark is also heavier than light. If you swim just below the surface of a lake, you see a lot of light. If you slowly swim deeper and deeper, you notice it getting slowly darker and dark. When you reach the depth of approximately fifty feet, you are in total darkness. This is because the heavier dark sings to the bottom of the lake and the lighter light floats to the top. The immense power of dark can be utilized to man’s advantage. We can collect the dark that has settled to the bottom of lakes and push it through turbines, which generates electricity and helps push the dark to the ocean, where it may be safely stored. Prior to turbines, it was much more difficult to get the dark from the rivers and lakes to the ocean. The Indians recognized this problem, and tried to solve it. When on a river in a canoe traveling in the same direction as the flow of dark, they paddle slowly, so as not to stop the flow of dark; but when they travelled against the flow of dark, they paddled quickly, so as to help push the dark along it’s way.

Finally, we must prove that dark is faster than light. If you were to stand in an illuminated room in front of a closed, dark closet, then slowly open the closet door, you would see the light slowly enter the dark closet; but since dark is so fast, you would not be able to see the dark leave the closet.

In conclusion, I would like to say that dark suckers make all of our lives much easier. So the next time you look at an electric bulb, remember that it is indeed a dark sucker.

Light Bulbs for Sale

Have you heard that the government is taking away your ability to buy light bulbs?  That it is illegal to buy certain types of light bulbs?  Well that isn’t necessarily the truth.  There are some light bulbs that the government has put a ban on the importation of in the United States.  Some of the light bulbs that have been affected by the ban have been the T12 Linear Fluorescent Light Bulbs, the PAR Halogen Lamps and the good old Incandescent Light Bulb.  But when they say the bulbs are banned, what they really mean is that manufacturers have had to come up with a way to manufacture the same type of light and call it something else.

The goal of the ban of light bulbs was to drive an energy efficient campaign in the US and try to get companies and residents to be more aware of their Energy Consumption and to be more conservative when picking out their lighting.  A Compact Fluorescent Lamp that is only 15 Watts produces the same amount of light as a 60 Watt Incandescent Lamp, using less than half of the energy. But a lot of people don’t like the long start up time that the Fluorescents have.  So then you can go to the 10 Watt LED Bulb and try your luck with the 50 Year Life span, but the large up front cost of the lamp has most people keeping their wallets closed.  So what options do you really have?

Well manufacturers have heard the cries of the public and have made some changes.  A standard 100 Watt Incandescent that you can no longer buy on the shelves is still available and some local locations until stock has run out.  The other option is to buy the new 80 Watt Incandescent that has been manufactured to replace the 100 Watt Bulb.  Most Manufactures have made some sort of reduced wattage incandescent bulb to replace the beloved 100, 75 and 60 Watt version of the Incandescent.

The main thing is that light bulb purchases have gone from a mindless purchase while out and about running errands, to a detailed planned out buy.  You can no longer walk into the store, see the bulb on the shelf and buy it. Now you have to know what type of light you would like to buy, how it fits into your energy consumption and what you are really wanting from you light.  The best bet is to call a lighting expert that can help you make the right choice in your lighting purchase.  Most employees at the big box stores are not trained in the details of lighting and don’t know what the difference between lights are.

No matter what state you are in, Have Lights Will Travel has the trained staff to help you with all of your lighting needs. Whether it is a question of which light is the best to purchase, or if you would like to place an order, Have Lights Will Travel is the place to call.  Call 775-355-6300 today and find out which is the best bulb for you.

Daylight Savings Woes

With warmer weather upon us and summertime rapidly approaching, most people are thinking about BBQs and baseball, fireworks and fun! As we head into another summer, starting with the setting forward of out clocks and marked with the first games of baseball, exterior signs and lighting is the last thing on everyone’s mind. But should it be? Most businesses provide longer hours during the summer to accommodate those patrons that are taking advantage of the longer days. And even if they don’t have the longer hours, there are still potential customers driving around while it is dark outside and passing by their buildings. This is why it is crucial to maintain the lighting and signage on a property, no matter what time the sun goes down.

One of the common misconceptions in parking lot lighting and signage is that it isn’t needed during the summer months due to the longer days. The lights may not even come on before everyone in the company has left for the day. However, the security function of exterior lighting is still crucial in providing safety to people that may be near your facility and to deter any criminal activity or vandalism that may occur on your property. As far as building or pole signage, an unlit or half out sign may represent a business that is closing or may not repair things as they should. By providing a sign that is bright and fully lit up, you are letting your customers know where you are and that you want their business even if the doors may be locked for the night.

One last thing to consider about the exterior lighting during the summer is that if it left unrepaired, it could cost more to repair later than getting it repaired now. Most high power lighting has two components in the lighting system: a lamp and ballast. The lamp is what produces the light, the ballast is what controls it. When a light pole or wallpack is not illuminated it is most likely that the lamp has gone bad and needs to be replaced. However, every time the power is turned on, the ballast tries to start up the lamp that is out if commission. Just like a parent trying to get their child to clean their room, the ballast will eventually wear out and stop trying to start up the bad lamp. If the lamp had been changed when it had first gone out, the ballast would have continued to work like it was designed and it wouldn’t have to be replaced. But since it wasn’t, the ballast will now need to be replaced along with the lamp, driving up the cost of fixing the light and leaving you with a frown on your face.

So next time a light goes out, make sure to have the professionals take look at it. Most likely, having it repaired will not only show your customers you care, but it will keep you safe and cost you less.

The History of the LED (from Wikipedia)

History

Discoveries and early devices

Green electroluminescence from a point contact on a crystal of SiC recreates H. J. Round‘s original experiment from 1907.

Electroluminescence as a phenomenon was discovered in 1907 by the British experimenter H. J. Round of Marconi Labs, using a crystal of silicon carbide and a cat’s-whisker detector.[7][8] Russian Oleg Vladimirovich Losev reported creation of the first LED in 1927.[9][10] His research was distributed in Russian, German and British scientific journals, but no practical use was made of the discovery for several decades.[11][12] Rubin Braunstein[13] of the Radio Corporation of America reported on infrared emission from gallium arsenide (GaAs) and other semiconductor alloys in 1955.[14] Braunstein observed infrared emission generated by simple diode structures using gallium antimonide (GaSb), GaAs, indium phosphide (InP), and silicon-germanium (SiGe) alloys at room temperature and at 77 kelvins.

In 1961 American experimenters Robert Biard and Gary Pittman, working at Texas Instruments,[15] found that GaAs emitted infrared radiation when electric current was applied and received the patent for the infrared LED.

The first practical visible-spectrum (red) LED was developed in 1962 by Nick Holonyak, Jr., while working at General Electric Company.[5] Holonyak first reported this breakthrough in the journal Applied Physics Letters on the December 1, 1962.[16] Holonyak is seen as the “father of the light-emitting diode”.[17] M. George Craford,[18] a former graduate student of Holonyak, invented the first yellow LED and improved the brightness of red and red-orange LEDs by a factor of ten in 1972.[19] In 1976, T. P. Pearsall created the first high-brightness, high-efficiency LEDs for optical fiber telecommunications by inventing new semiconductor materials specifically adapted to optical fiber transmission wavelengths.[20]

Commercial development

The first commercial LEDs were commonly used as replacements for incandescent and neon indicator lamps, and in seven-segment displays,[21] first in expensive equipment such as laboratory and electronics test equipment, then later in such appliances as TVs, radios, telephones, calculators, and even watches (see list of signal uses). Until 1968, visible and infrared LEDs were extremely costly, in the order of US$200 per unit, and so had little practical use.[3] TheMonsanto Company was the first organization to mass-produce visible LEDs, using gallium arsenide phosphide (GaAsP) in 1968 to produce red LEDs suitable for indicators.[3] Hewlett Packard (HP) introduced LEDs in 1968, initially using GaAsP supplied by Monsanto. These red LEDs were bright enough only for use as indicators, as the light output was not enough to illuminate an area. Readouts in calculators were so small that plastic lenses were built over each digit to make them legible. Later, other colors grew widely available and also appeared in appliances and equipment. In the 1970s commercially successful LED devices at less than five cents each were produced by Fairchild Optoelectronics. These devices employed compound semiconductor chips fabricated with the planar process invented by Dr. Jean Hoerni atFairchild Semiconductor.[22] The combination of planar processing for chip fabrication and innovative packaging methods enabled the team at Fairchild led by optoelectronics pioneer Thomas Brandt to achieve the needed cost reductions.[23] These methods continue to be used by LED producers.[24]

As LED materials technology grew more advanced, light output rose, while maintaining efficiency and reliability at acceptable levels. The invention and development of the high-power white-light LED led to use for illumination, which is fast replacing incandescent and fluorescent lighting[25][26] (see list of illumination applications).

Most LEDs were made in the very common 5 mm T1¾ and 3 mm T1 packages, but with rising power output, it has grown increasingly necessary to shed excess heat to maintain reliability,[27] so more complex packages have been adapted for efficient heat dissipation. Packages for state-of-the-art high-power LEDs bear little resemblance to early LEDs.

The blue and white LED

The first high-brightness blue LED was demonstrated by Shuji Nakamura of Nichia Corporation in 1994 and was based on InGaN.[28] Its development built on critical developments in GaN nucleation on sapphire substrates and the demonstration of p-type doping of GaN, developed by Isamu Akasaki and H. Amano in Nagoya.[citation needed] In 1995, Alberto Barbieri at the Cardiff University Laboratory (GB) investigated the efficiency and reliability of high-brightness LEDs and demonstrated a “transparent contact” LED using indium tin oxide (ITO) on (AlGaInP/GaAs). The existence of blue LEDs and high-efficiency LEDs quickly led to the development of the first white LED, which employed a Y3Al5O12:Ce, or “YAG“, phosphor coating to mix (down-converted yellow light with blue to produce light that appears white. Nakamura was awarded the 2006 Millennium Technology Prize for his invention.[29]

The development of LED technology has caused their efficiency and light output to rise exponentially, with a doubling occurring approximately every 36 months since the 1960s, in a way similar to Moore’s law. This trend is generally attributed to the parallel development of other semiconductor technologies and advances in optics and material science, and has been called Haitz’s law after Dr. Roland Haitz.[30]

In 2001[31] and 2002,[32] processes for growing gallium nitride (GaN) LEDs on silicon were successfully demonstrated. In January 2012, Osram demonstrated high-power InGaN LEDs grown on Silicon substrates commercially.[33] It has been speculated that the use of six-inch silicon wafers instead of two-inch sapphire wafers and epitaxy manufacturing processes could reduce production costs by up to 90%.[34]
