Why Does a Sodium Street Lamp Give Off a Different Color of Light Than a Neon Light?

Neon, IIRC, has an orange cast to its glow while sodium has a yellow cast to its glow. The color comes from photons being emtted as electrons fall from a higher energy orbitals into a lower energy orbital. The energy difference between orbitals in neon is different from the energy difference in orbitals in sodium.

1. A street lamp weighs 150 N it's supported by two wired that form an angle of 110 with each other?

the vertical component of the tension in each wire supports half of the weight of the streetlamp the wires each form a 55 angle with the vertical (110 / 2) t cos(55) = 150N / 2 for an 80 included angle ___ t cos(40) = 75N

2. 1'16 scale street lamp 1940s?

I would get a good picture of the lamp post and head, then it's off to the hobby shop for some brass tubing, wire and wheat germ light bulbs

3. What does it mean when a street lamp goes off upon reaching it?

ah faulty wiring??

4. why does a sodium street lamp give off a different color than a neon light?

When atoms are sufficiently excited, electrons are promoted beyond the outer shell and the atom ionises. When the electron falls back again, the energy is re-emmitted as light. the wavelength of the light [it's colour] depends on the element. Hence neon gives a red light and sodium a yellow light. Incidentally, most sodium street lights contain neon as well and are red when they first come on .. when they heat up and the sodium starts vaporising, the familiar yellow appears as this colour is so intense that it swamps the weaker red.

5. would You rather be a Street-LAMP or a LAMP-Shade?

Street lamp, no question. To shine instead of shadowing another light. Be out there, meet people (or dogs at least)

6. Why would my AC unit make the street lamp turn off?

Your AC Unit probably uses a lot of energy when you turn it on, thus making the light go out

7. where can i park my bike in the city if theres no bike racks?

Park it next to a solid post like a power pole or street lamp and chain it up with a solid logging chain in a plastic hose that will not scratch your bike with a hefty padlock. Do not use a street sign or anything that can be removed with 1 bolt. U bolts and cables are junk. Ask any bike courier. Chain up both wheels as well and anything else that can be easily removed. good luck.

8. why does your shadow lengthen as you walk farther away from a street lamp?

had to do with angle

9. would You rather be a Street-LAMP or a LAMP-Shade?

Lamp shade, dogs pee on street lamps

10. Does anyone know anything about the very large dragon street lamp in Venice Italy?

I will take a look at it tomorrow...I am actually in Venice!!! Ciao... Got there and saw the dragon..though nobody knew about it...it's pretty neat

11. Is a landlord required to have a street lamp on a street when they rent every house on the street?

The only time I've ever seen privately maintained street lights is out in the country

12. would You rather be a Street-LAMP or a LAMP-Shade?

A street lamp so I could be the beacon of light that guides people to their front doors every evening. Keeping them safe from harm

13. Why is a street lamp's orange light become white before turning orange?

as the electricity is started the lamp begins to glow the wave lenght of photons emitted is large and in not much hot at that instant later after some time it will get hotter and emit photons of smaller wave length as you knoaw orage is smaller wave lenght than white

Development Direction of Solar Street Lamp Manufacturers
Development Direction of Solar Street Lamp Manufacturers
There are many solar street lamp manufacturers. In the face of fierce competition in the industry, solar street lamp manufacturers have to face some problems if they want to develop. If they want customers to find you or patronize you again, the premise is that you are a good manufacturer in all aspects, What kind of development direction should solar street lamp manufacturers have now?If the solar street lamp price has an impact on customers, it can only be that the solar street lamp manufacturer has not really succeeded. Because the price war is never an inevitable factor for the development of manufacturers. Today, you can give customers a very low price and reduce the street lamp price by reducing the Watts actually needed by customers. It may not be guaranteed that another manufacturer will use the same method to reduce the price and attract customers. You are lowering the price, and your opponent is also lowering the price. In this way, long-term development will only hurt both sides.Therefore, the price war is not the correct development direction of solar street lamp manufacturers. The correct direction should be to focus on product production, improve product quality and cost performance, and do a good job in after-sales service at the same time. It's like a 99 yuan smartphone and a Samsung phone with hundreds or even 3000 yuan. There is a big difference in price, but we still choose Samsung phone because of its high brand, good performance and cost performance in all aspects. Therefore, the development direction of solar street lamp manufacturers should not tangle in price, but do a good job in their products and improve their brand.

I Would Like to Ask What Are the Ways to Improve the Brightness of Solar Street Lamps?
I would like to ask what are the ways to improve the brightness of solar street lamps?1. Determine the brightness of LED solar street lamp before purchaseBefore purchasing solar street lamps, if it is a large number of recycling, the best thing is to choose manufacturers with industrial plants and drive to the processing plant to have a look. If you decide where to buy, you must talk to the other party about the regulations on chromaticity. If you don't have much definition of this chromaticity, you can let the other party make a sample to have a look.If the requirements for chromaticity are very high, the size of LED light source should be larger. Some manufacturers will choose the most suitable scheme for you out of your own consideration. If it is not particularly bright according to your specific situation, you can also listen to the manufacturer's suggestions.2. Lower the LED solar street lamp equipmentIf solar street lamps are to be installed on both sides of the road, we should fully consider whether there are green plants on both sides of the road. Because the solar street lamp is converted into electromagnetic energy by digesting and absorbing solar energy, if something blocks it, the actual effect is undoubtedly impossible to be very good. When such a situation does occur, why not reduce the height of the solar street lamp and not completely cover the solar panel.3. Query LED solar street lamps on timeMany solar street lamp projects are not easy to hold meetings after the equipment is good, which is naturally not very good. Although solar energy does not need maintenance or cleaning by full-time personnel, it must be queried on time. The damaged position should be repaired immediately. If the solar panel has not been removed for a long time, it also needs to be inadvertently scrubbed.

Count the lamps according to the delivery list: disassemble and check all parts one by one with reference to the packing list, and check whether there is any damage such as collision, wear, deformation and scratch. The installation of unqualified products is prohibited.4. The lamp pole components and easily worn accessories (components and lamp caps) must be padded with soft pads to avoid unnecessary damage such as scratches during installation.5. When the lower lamp pole assembly is placed, its upper end must be supported by an iron frame to facilitate the installation of the upper lamp pole assembly.1. Assembly of lamp pole assembly: upper lamp pole assembly, lower lamp pole assembly, lamp arm assembly and solar cell assembly fixing structure.A. Install the lamp arm: bind the exposed sheath wire end on the lower lamp pole with thin iron wire and wrap it with black tape: the other end of the thin iron wire passes through the lamp arm assembly; Slowly pull the thin iron wire at the top of the lamp arm assembly so that the thin iron wire with the movable sheath wire passes through the lamp arm assembly. At the same time, the lamp arm assembly gradually approaches the lower lamp pole until the panel on the lamp arm is aligned and close to the lamp arm boss on the lower lamp pole, and then fasten the lamp arm assembly on the lower lamp pole with appropriate bolts; When fixing the lamp arm assembly, avoid squeezing the sheath wire, resulting in damage or even cutting of the sheath wire skin; Disconnect the thin wire from the sheath.B. Installation of lamps (equipped with equal source): close the opened lamps to the upper end of the lamp arm, and the exposed sheath wire passes into the lamps from the tail of the lamps; Pull the sheath wire and insert the lamp into the lamp arm at the same time. The overlapping length of the two is 150mm; Connect the sheath wire to the wiring terminal inside the lamp, and pay attention to the correct positive and negative wiring during wiring. Rotate the lamp with the lamp arm as the neutral so that the lampshade is facing the ground, and then fix the lamp on the arm; Turn off the lights.C. Pole assembly on assembly:1) Fasten the bracket assembly and corner post on the upper lamp post assembly in turn, and the threaded connection parts shall be stressed evenly and fastened; While connecting the support and the angle steel frame, use fine iron wire to lead the sheath wire from the lamp pole to the angle steel frame through the support assembly;2) . place the component guard in the angle steel frame, and then place the component on the guard; When placing the components, the junction box shall be at a high place. When the components are placed horizontally, the junction box shall be close to the light pole assembly;3) . connect the components according to the system voltage and component voltage of the street lamp. If the system voltage of the street lamp is 24V and the component voltage is 17V or 18V, the components shall be connected in series. The series connection mode is that the positive pole (or negative pole) of the first component is connected with the negative pole (or positive pole) of the second component. If the component voltage is 34V, the components shall be connected in parallel, The parallel method is to connect the positive and negative poles of the first component and the positive and negative poles of the second component correspondingly. When connecting, press the small slotted screwdriver to the terminal of the junction box. The red wire is required to connect the positive pole and the blue wire to the negative pole. After wiring, fasten the anti nut at the outlet end of the junction box, and apply 7091 sealing silica gel at the terminal of the junction box, The amount of glue shall be subject to the complete sealing of the incoming line in the junction box, and then the junction box cover shall be fastened without reverse buckle.4) Use a multimeter to detect whether the component wiring (connected to the controller end) is short circuited, and also to detect whether the component output voltage meets the system requirements. In fine weather, the open circuit voltage shall be greater than 18V (system voltage is 12V) or 34V (system voltage is 24V). After installing and testing the components, the power line is connected to the positive pole of the controller end, and the exposed wire core shall be wrapped with insulating tape, which shall be wrapped in two layers;Note: the components shall be handled with care during installation to avoid damage to them by tools and other instruments.5) , components and component supports are fastened with M6 * 20 bolts, N6 nuts and washers 6.

This Can Be Done When the Solar Street Lamp Cannot Work (I)
This Can Be Done When the Solar Street Lamp Cannot Work (I)
1 Power loss of solar street lamp: the power loss of solar battery is due to the quality problem of the battery itself. The cheapest one is 2-3 yuan 1Ah. Generally, this is not very reliable. Problems continue to occur after using it for about a year. Therefore, to solve this problem, replace the solar battery and replace it with a better manufacturer, If it is a northern city, it should also be noted that the battery must be buried below the frozen soil layer, especially in cold places. Thermal insulation cotton should be added to the battery, because the capacity of solar energy storage battery has a great relationship with the external ambient temperature.2 The LED light source of solar street lamp is not on: it may be the most direct way for the performance of solar street lamp. The solar street lamp system is abnormal, that is, it is not on. One of the reasons why the solar street lamp is not on may also be the problem of LED light source. As a general purchaser, it is difficult to distinguish high-power LED light source. If the solar street lamp is not on, You can simply check the light source by yourself. If the system is small and the system voltage of the light source is 12V or 24V, the conventional configuration is used. The best way to detect the light source is to connect the battery directly to the light source. If the light is on, it proves to be normal.For more questions, please click the right figure to consult online customer service.
Solar Street Lamps Are Common in Daily Use
Solar Street Lamps Are Common in Daily Use
First, the lights of solar street lamps flicker and the brightness is unstable. In case of this phenomenon, the first thing is to replace the lamps. If the lamps are replaced or flicker occurs, it can be determined that it is not the problem of the lamps. At this time, it is necessary to check the line. It is not ruled out that it is caused by poor contact of the interface of the line.Second, solar street lamps can only last for one or two days on cloudy and rainy days. The main reasons for this phenomenon are as follows:1. The charging of solar battery is not satisfied. The charging dissatisfaction of solar battery is the reason for solar charging. First, observe the recent weather conditions and whether it can ensure charging for about 5-7 hours a day. If the charging is only 2-3 hours, it is normal. Please rest assured to use it.2. Check whether the solar battery is aging. Under normal working conditions, the service life of the battery is 4-5 years.Third, when the solar street lamp stops working, we should first check whether the controller is normal, because generally, such a situation will occur. A great reason lies in the solar controller. If so, we should carry out maintenance work in time.Fourth, when installing solar street lamps, do not let the solar panels be blocked by foreign objects, so that they can normally absorb solar light for charging. The maintenance and cleaning of solar street lamps should be carried out periodically, especially in some dusty areas, the cleaning frequency should be once a year, while in areas with relatively little dust, the medium frequency rate can be adjusted once every three years to ensure the normal charging of solar panels.For more questions, please click the right figure to consult online customer service.
