Talk about the purchase and production of LED lighting
We are now familiar with LED (light emitting diode). From LED backlit TVS to LED flashlights, they can be found on traffic lights and large billboards.
As a daily lighting, why choose LED lights? You need to know the benefits:
Environmental protection, LEDS do not contain mercury and other highly toxic volatile substances like fluorescent lamps. If a fluorescent lamp breaks indoors, it can immediately cause mercury to evaporate neatly into the air. Mercury is highly toxic.
Safety. Leds are stronger than fluorescents and CFLS.
Energy saving, LED luminous efficiency is higher than fluorescent lamp and energy saving lamp. A 4W LED lamp can be equivalent to a 14W CFLS or a 40W halogen lamp. With 4W led tape light, use for 8 hours a day. The annual power consumption is about 11680W, equal to about 11.7 KWH. Using 10 bulbs, the annual electricity bill is about 70.2 yuan. And 10 energy-saving lamps of the same brightness cost about 245.4 yuan a year! It costs 700 yuan for 10 incandescent lamps! [If it is not accurate calculation, do not take it seriously]
The life of LED is usually 50,000 hours, the life of ENERGY-SAVING lamp is 6,000 hours on average, and the life of incandescent lamp is only about 1,000 hours. After LED to life, it is not like other bulbs to directly die, LED so-called life, refers to LED luminous efficiency is only 70% of the initial light effect. That means it’s just dimmed, but it keeps working, so you don’t have to climb a ladder every few years to change that hard-to-reach light bulb in the ceiling. This may be especially important for women who can’t change a light bulb themselves.
Gold is not pure, talk about the shortcomings:
Expensive, high-quality LEDS are nearly twice as bright as CFLS.
LED lights emit light at a limited Angle. The back of the LED is almost dark. To solve this problem, a special design is required.
High power LED lighting has high heat output.
High power leds cause blue light damage.
What are blue light hazards?
In the last decade, we’ve been surrounded by more and more light, especially blue light, and exposure to blue light can cause eye damage, especially macular degeneration. Stanley points out that visible light is the part of light that human eyes can perceive, including red, orange, yellow, green, blue, indigo, violet and so on. The invisible part is called invisible light, including infrared, ultraviolet and other light. One of the most recent studies shows that blue light – can cause serious damage to the eyes. Blue Light is the most energetic part of visible Light that is closest to ultraviolet, and its wavelength is between 400 nm and 500nm. Because the color of this wave length is between blue and green, it is considered to cause so-called “blue ray harm” to the retina. The main sources are the sun, computer, machinery, laser, welding light, xenon lamp, mercury, neon red light, office lighting, etc.

Let me just say two things about the dangers of blue light to avoid unnecessary controversy:
Blue light damage is present at all color temperatures.
The degree of damage is related to the power.
According to experiments, the effective way to prevent the harm of blue light is to use a soft mask (translucent diffuser).
If you use LED lights at home, be careful not to let children and the elderly look directly at the exposed LED light beads, so as not to cause eye damage.
Judge for yourself: If you feel that the LED lights are harsh and uncomfortable, stop using them.
An LED lamp is generally composed of three major components: shell components, drive power supply, LED. So let’s start with these three areas.
The first is the shell component:
Housing components are divided into metal and non-metal. Both have advantages and disadvantages. The following two are products of good vision. The left side is a 5W LED and the right side is a 4W LED.
Talk about the purchase and production of LED lighting
Because the LED light is very hot, and the internal circuit. To keep the circuit from burning, high-power LED lights must use metal enclosures to help cool the heat. Therefore, the purchase of metal lamp body, to see whether the radiator, large. The greater the power of LED lights, the heat sink must be proportional to the large!
Seeing this, you may be tempted to choose a metal lamp body. But there is a problem with the metal body, and that is safety. In case, I mean in case, there is a leak in the internal circuit and the metal body is charged, which could be very fatal to a child who doesn’t know electricity. Therefore, metal LED lamp body, do not recommend to use in children’s homework desk lamp!
Or because of the heat, the power of the PLASTIC LED lamp body can not buy too much. There are many kinds of plastic lamp body, ordinary ABS plastic deformation temperature is 90 degrees, ordinary PC thermal deformation temperature is 135 degrees, PBT+20%GF thermal deformation temperature is 217 degrees. Be careful when you buy. The deformation temperature is not the same under different pressures, the value here is just a diff. According to a non-Chinese standard, plastic shell can be used below 5W.
The second is the internal drive circuit:
Although said LED life is 50,000 hours, but the drive circuit is not to force, the 50,000 hours can only be wasted. The quality of the drive circuit directly affects the life of the LED lamp, because most of the finished LED lamp shell is not detachable, so once the drive circuit is broken, the whole LED lamp only LED has the value of reuse. Since it is also impossible to disassemble, the electronic originals used will not be discussed here.
The high temperature of LED lamp will directly affect the life of the drive circuit. If you choose the NON-metallic LED lamp body, it is recommended to choose the big brand with quality guarantee!
The most important LED beads:
LED beads have a life problem, and that life is reflected in their light decay. Popular saying is: the more used the darker. The life of a good LED lamp bead can reach tens of thousands or even hundreds of thousands of hours, and the so-called life refers to the light is only 70% of the initial time. If you want to buy LED lights at a particular house, it is recommended to buy two leds first, and then burn one for a month and compare it with the other to see if it becomes significantly darker.
Now most of the TB market “made by yourself” cheap LED lights are chosen is 1 watt power sub-installed LED lamp beads. This kind of lamp bead has a problem, it is unit area hair bright is very big, blu-ray harm is bigger, popular say is dazzling a few. Choose this kind of LED lamp, recommend to buy cream white soft light cover version.
