Soldering Iron Holder

Poles Of Other Sorts? Energy

Why are some energy-saving lamps sold a few yuan, 20 yuan more than a dozen others to sell it?

Determining a cost of energy-saving lamps are many factors that we have to analyze the cost of the following conditions: 2U9W energy-saving lamps do cost comparisons and performance comparison.

1. Capillary

glass of poor quality, typically capillary loaded with goods manufacturers, defective, substandard goods equivalent to superior product capillary only 1 / 3 to 1 / 5 the price.

the ordinary halogen phosphate phosphor, calcium phosphate theory that brine is not used for energy-saving fluorescent lamp phosphors, because of its low light efficiency, color rendering index is low, does not apply to a large lumen diameter less than 30mm fluorescent lamps, it's priced at 30 yuan / 1kg yuan.

other filament materials, such as manufacturers of electronic powder has been purchasing substandard goods, defective, or no quality assurance of small factories.

As the manufacturers of such capillary crudely, he does not need any technical staff, managers, technical staff and equipment.

The product sold at 0.9 yuan / or so.

superior quality glass tube, the capillary is generally excellent product manufacturers or first-class products.

three phosphors with high efficiency, compared to halogen phosphate phosphor, it has a high luminous efficiency, high color rendering index, light a small decline, it is applicable to less than 30mm diameter fluorescent, but not larger than 30mm fluorescent lamps, it's priced at 800 yuan / 1kg yuan.

In order to ensure product quality manufacturers in the technology, quality management, process and equipment is very hard.

this product sold at 4 yuan / or so.

2, plastic lamp holder

lamp manufacturers used substandard materials, the same lamp manufacturers such as iron lamp unqualified about 0.03 yuan / support, because it does not meet national standards (size, rust-proof capability) will be encountered during use is not screwed into the light Block within, or screw into easily fall off.

Plastic parts are ABS plastic, the plastic lower prices than were small, heat resistance and flame resistance are poor, it is easy to fire.

It costs about 0.25 yuan each about energy-saving lamps.

iron lamp manufacturers use the same quality product or Grade (national standard) cost around 0.15 yuan / only

PBT flame retardant engineering plastics, less than 180 in temperature to work long hours without distortion, and with good flame resistance.

it cost 1 yuan each.

3, electronic ballast components

circuit board does not have a flame retardant used in the circuit board, this board book, with a poor effect of copper, copper toggle easily lead to skin.

seize electronic element such as resistors, diodes, capacitors are generally the same with some of the more regular factory production line one by one station to play down the unqualified, or some no-name manufacturers, and these dollars to buy plenty of press kits to seize the standard, some by tons of standard.

For some transistors, inductors and other items are also free to buy some small manufacturers, product quality and no protection, but it is no sorting capabilities, and will not go to sorting.

the cost of an electronic ballast components are mostly in 2-3 yuan.

circuit board using a flame retardant in circuit boards, such circuit board thickness, with a bronze effect, high temperature, no distortion, no copper Rocker prone skin.

electronic component manufacturers have generally adopted formal quality assurance capacity of the manufacturers of quality product, or first-class products. Buy this component to a calculation of the general and first payment.

for some of the more important components, such as: electrolytic capacitors, transistors, etc., generally used in the import, or domestic manufacturers with the ability to protect and plant selection to match the sub-parameters.

an electronic ballast components cost about 7 yuan.

4, technical state

basically no technical staff, even if there is some relatively poor, while there is no test instruments, meters, do not have the development ability, just copy copy someone else's style.

technical staff have very good quality, experienced.

test instrument, apparatus, are relatively complete.

with new product development capability, according to different raw materials with different parameters to adjust.

5, production conditions and quality status

the production just the original purchase to assemble, to light on OK.

Because it is funded by piece, without any management, quality control personnel. What the production does not require equipment, Aging equipment, testing equipment.

its processing costs of about 0.1-0.2 yuan.

production is put through checks at each level, filtering, sorting out the original device from time to time in accordance with the procedures of a process, produced.

As a result of assembly-line, more efficient, more stringent quality control, production equipment, testing equipment, more complete.

product Burn to go through before the final factory.

processing costs about 1 yuan.

6, integrated

Integrated on the analysis, we can see that low energy lamps can make out a few dollars, but it is like a garbage processing plant to refuse to buy back for processing and assembly, and then sold to users. Consumers may buy back waste, trouble and fire.

Good product manufacturers the above analysis is in line for the sake of users, producing a high cost performance products to the user.

Fourth, the performance of energy-saving lamp:

Safety: circuit board, wire, coil the flame-retardant high-temperature materials are used, the shell (BT material, line power factor greater than 0.9, third harmonic content is low (less than 12%) on the network and other equipment guiltless rope .

life: average life expectancy of more than 7000 hours, and one year warranty.

tricolor fluorescent lamp with high efficiency, water powder coating, coating technology made color index 80 ±

About 5, color tolerance 5.

electronic ballast components are made of quality-assured manufacturers, the key components into products using the original device, dual wave soldering machines Soldering, and gradually began to SMT technology applications.

pluggable bubble tubes imported jump start the fast, long life.

How can a power a single led with a power supply?

I want to power a single led with a power supply from the wall. I use just a single blue led for a nightlight for my aquarium. Anyway, how it runs now is the led is a 3.8v and it is connected to a resistor, then to some lamp cord like copper wire, and then to a 4 "AAA" battery holder with on/off switch that i got from radioshack. I dont want to keep using batteries to power the led since it will cost a lot to keep changing batteries when i want to run it on average 6 hours a night. It is just my little diy project i am trying. I just want to know how to wire the led to a power supply to the wall. I know nothing about electric as far as that. Like can use a cell phone charger or some other type of plug? I don't know. Just tell me what parts i need and how to do it. I have a soldering iron at home, so i guess thats a plus.

You'll need a transformer with the correct output voltage. Radio Shack should be able to help.
