First part (what is LED)

LED stands for Light Emitted Diode. Light emitting diodes are basically part of the family of diodes that are under the group of semiconductors. The property that distinguishes LEDs from other semiconductors is that some energy is emitted in the form of light when current passes through them. Until the end of the last decade, LEDs could only produce three lights: blue, green, and red. This caused their limited use. But today, they exist in the market with various colors including ultraviolet, purple, blue, blue-green, green, yellow-green, yellow, orange, red, dark red, infrared and white (cool, warm, natural, etc.). This is why they are widely used in modern lighting.

The second part (advantages and disadvantages of 9 watt LED lamps)

Disadvantages:

In most cases, the failure of the LED lamp is due to its rectifier circuit.
The rectifier circuit increases the price of the lamp.
They cannot emit light in all directions and this causes dark spots behind the lamp.
Some researchers in research centers around the world believe that LED lamps should not be used in streets and passages. Because by producing light like sunlight, it affects the day and night system of the human body and causes disruption and problems that have not yet been accurately proven or denied.
The waste left from the broken LED lamp is very harmful to the environment.
The things released from LED lamp waste in the space are the cause of diseases such as skin cancer

The fourth part (the description of each of the 9 watt LED lamps was introduced)

1_ Solar LED lamp:

Solar energy and LED are a perfect combination, like milk and cookies! While they have the best features of each, they are combined with each other and provide you with the best and least consuming system. Why do they work so well together? Well here are a few reasons. LED lamps work with DC electricity. The old standard of using CFL or other types of lamps in solar lighting applications always requires some kind of converter to run the light. This would cause the loss of electricity, but the solar energy compensates for it by increasing the size and additional storage of the battery. Since LEDs work directly from DC power, there is no need for a converter or additional power to compensate for this loss. This means that solar can be more efficient while providing better lighting in fewer watts than everyone else. LEDs LEDs offer the best efficiency and lumen-to-watt ratio, which means they are very economical.

These lights work with the help of photovoltaic effect. Solar cells are the most important component in a solar panel, because these cells convert solar energy directly into electrical energy. The solar panel absorbs the electrical energy in the inverter to be stored in the battery and used immediately or later.

The solar cell consists of many silicon and chemical crystals that have created layers with negative electron charge and positive charge space. When the sunlight shines on the solar cells, the electrons are excited and move towards the positively charged space. Then the electrons are attracted to the wires connected to the battery from inside the panel. Solar Panel Solar Panel fully charges the battery during the day and when the sunlight shines, and during the night when the sunlight weakens, the solar cells stop. And also, solar energy is cost-effective. Maybe the initial cost you pay when buying a lamp and solar panel is high, but after installing it, you will not pay any electricity cost, which in the long run will save you the cost of paying for the lighting system. You would do it, it will happen. Solar energy is an unlimited resource. Solar energy is inexhaustible. As long as you live in a new place

When the sun shines on it, there is no reason why you can't store it in the panel and use it. They need little maintenance and also, among the places where LED lamps can be installed, you can...

2_ Deep LED lamp:

DIP LEDs are the oldest generation of LEDs, although they still have many applications in various industries, but due to their shortcomings, other families of LEDs were designed and built, which solved all the disadvantages of DIP LEDs.

The useful life of this family is a maximum of 15,000 hours, which is much lower compared to the new generations of LEDs.

Among the limitations of DIP LEDs, the following can be mentioned:

1- The amount of light density means that a high amount of light can be produced in a very small space.

2- Very low powers of DIP LEDs and the impossibility of producing them with high powers

3- The impossibility of using DIP LEDs for lighting purposes and only limited to decorative applications

4- Short life span

In the early 1960s, this LED lamp was used to make the LED dip lamp, and it was also known as the old or normal LED lamp. With the development of lamp manufacturing technology, the lighting system in the early 21st century and due to monochromaticity and low light efficiency, the use of this type of lamp was limited. Today, the dip lamp is used in special cases, such as traffic lights, city billboards, and displays with the ability to see far away.

It is worth noting that the efficiency and efficiency of LED lamps is much lower than the lamps that can be found in the market today. The chips that are used in the birth of these types of lamps are circular or ball type.

3_ SMD LED lamp:

Mehtabi LED SMD is a type of SMD lamp that uses SMD technology in its production and therefore has high luminous flux and low power consumption. This moonlight has a CRI or color separation index above 80, for this purpose, the objects placed in its brightness range are seen very close to their true color. And the term "SMD lamp" or "SMD lamp" means that In the process of making the electronic board in the lamp or LED light, ICs, chips, diodes or resistors are separated from their respective rolls by air pressure using devices specifically designed for use in this sector. They are connected to the board by disconnection. And in general, the products that have been produced using this technology are called SMD LED products.

Another point regarding the interface of the SMD lamp module, for the manual assembly of SMD electronic components, you can use the 0.4 thin solder wire available in the market, but if you intend to produce electronic boards on a semi-manual scale, we recommend using the stencil with the available solders. Make and use a laser device in the market. With this method, it is enough to engrave your design with a high-power laser machine on the metal. Keep in mind that if you set the device to cut mode, the edge of the design will melt due to heat and your stencil will be unusable. After that, with a spatula and some tin paste, you can start tinning and then arrange the pieces. Surface mount components (SMD) are very different from DIP based elements based on their construction, and are divided into several groups. The first group is Passive SMD elements.

Many types of passive SMDs are used, however, most passive SMDs include resistors and capacitors in standardized sizes.

Other parts include coils, crystals in their own special shapes. SMD capacitors and resistors are available in various sizes. In designs 1812, 1206, 0805, 0603, 0402 and 0201, these numbers indicate the dimensions of the piece in hundredths of an inch. For example, 1206 represents the dimensions of 12 hundredths of an inch by 6 hundredths of an inch.

0603: The dimensions of the piece are 6 hundredths by 3 hundredths of an inch

Larger dimensions such as 1812 and 1206 were among the first SMDs made and today they are not used as widely as smaller parts, however, they are used in electronic boards where high power levels are required or in special requirements where larger dimensions are required. . These SMDs are connected to the printed circuit board through the metal areas at both ends of the element.

4_ LED COB lamp:

COB stands for Chips on Board. In this technology, a large number of micro LED lamps with low power, with a small distance and the same size, are arranged next to each other and on a plate, then they are covered with silica gel or resin, and when lit, they form a luminous plate. One hand can be seen.

Among the features of this technology, we can mention a long life of about 50,000 hours, which is older than other light sources, as well as low energy consumption and high light production, which has attracted the attention of consumers. A lot of light in LEDs in some applications can also be considered as negative features of these LEDs in such a way that looking directly at these LEDs can cause eye irritation. One of the solutions to solve this problem is to use light diffusers. However, this method significantly causes the rejection and wastage of light. In COB lamps, due to the fact that they spread the light over a larger area, it causes less eye glare than other LEDs. LED is designed in such a way that it can

It should be more efficient in small optical dimensions. For example, a small LED light source can at best produce up to 249 lumens of light per watt and 20 milliamps of current, while a larger LED light source can produce up to 161 lumens per watt and can produce light for 350 milliamps of current. This reduction in light efficiency is achieved due to the larger size and more current draw. To solve this problem, COB lamps are made of a set of small LED lamps on a board, and this means more light efficiency than other LEDs. The goal of designing and producing COB lamps is to create light sources with high efficiency. is, in such a way that by reducing the current consumption and the heat produced, the resulting lighting is completely cost-effective and economical. One of the most important features of the LED COB lamp is that now by hiding the light source, you can create more beautiful lighting. Due to the extraordinary and high quality light, it can replace fluorescent lamps. Make a significant saving compared to them.

The fifth section (introducing the types of lamps in terms of structure)

2_ Downlight lamp

3_Filament lamp

4_ LED wall washer lamp

Part six (explanation of each of the introduced structures)

1_ Bubble LED lamp:

One of the most widely used light bulbs in buildings, which can be found in abundance in most places and rooms, is the bubble LED lamp, which is available in different temperatures and colors with low energy consumption. The lifespan of most of this type of LED lamp is about 25,000 hours, and the luminous efficiency of the bulb lamp is between 120 and 200 lumens per watt. A matte plastic cover is also installed on the LED screen for uniformity and distribution of light, and the body of most of them is made of compressed plastic.

In some bubble LED lamps that have an aluminum body, due to better heat dissipation and heat transfer, the lifespan of this type of lamps is about 50,000 hours, and they are also lit with the voltage of 220 V city electricity and the frequency of 50 Hz of the home system. Some features of the bubble lamp are:

Equal, wide and gentle distribution of light in space
The use of an all-plastic and shock-resistant body
Installation in reverse
Different colors of lighting, including sunny, moonlight and icy
2_ Downlight lamp:

A downlight is a lamp that is placed inside the ceiling and is completely surrounded. These lights emit light in the form of a narrow beam downwards. They use different types of Don Light to provide the light layer in the architecture of the interior space. When the lights are turned on, the place where they are installed looks like glowing spots. This unique feature in the Donlight lamp makes it popular among people. Downlight has other names such as recessed light, pot light and can light. In Iran, this lamp is known as a downlight, but it is more commonly known as a built-in ceiling light or a built-in ceiling lamp. In terms of their application, I must say that Mazi Noor downlights can be an excellent choice for lighting your home. Because they can be anywhere in the house...

For example, it can be used in the living room, in the bedroom, in the bathroom, in the kitchen, or even under the kitchen cabinet. Downlight lights are also very flexible in terms of the amount and type of light it provides. For example, they are perfect for use as task lighting, where you need a lot of light. In addition, they are also suitable for ambient lighting. Downlight lights look very beautiful! Especially if you don't want to use a hanging lamp or a big lamp in your room, Mazi Noor downlights are very simple, clean and excellent. Downlights are round in shape. However, there are many types of downlights that you can choose from. The difference is primarily in the type of bulb you use. Currently, the most common type of bulb used in downlights is the halogen bulb, but you will soon notice that CFL bulbs (compact fluorescent bulbs, or low-energy bulbs) and LED bulbs will be used due to the popularity of more energy. took Depending on the type of lamp you use, the downlight can be dim.

3_Filament lamp:

Filament lamp is a type of LED lamp, which is made similar to old incandescent lamps. This type of lamp spreads heat easily and produces less heat than other lamps due to the diffused diodes. This lamp is not only beautiful, but it can save up to 90% of energy consumption and greatly reduce the cost of the electricity bill.

Edison lamps or filament lamps have not been popular for a long time, but in this short period of time they have been used in many interior designs and decoration of different spaces because creative designs can be created by using these lamps. It gave a special effect to the space. Types of LED filament lamps or tungsten lamps are used as elements of design and decoration of the space and have bubbles of different shapes, each of which can be used for lighting.

In general, if we want to examine the construction of filament lamps, we find that these products are one of the newest lamps, which are actually in the category of LED lamps, but they heat up less, and they also have a beautiful shape in terms of appearance and light. And they consume less electricity than old incandescent lamps. Filament lamps or Edison lamps can be used in chandeliers,

used for home decor, lighting of different environments, etc. Also, it is recommended to use this lamp for chandeliers with a shade (cap) because high heat lamps cause these shades to burn. These lamps are not recommended for bubble chandeliers because in such chandeliers the lamps are It is rarely seen and it is not recommended to use this type of lamp, which is much more beautiful than other lamps, and it is also more expensive in terms of price than other lamps. This lamp is available in two forms: candle bulb (E14) and large bulb (E27) in sunny and moonlight colors.

4_ LED wall washer lamp:

Wall washer is a relatively new and practical lighting element that is made by combining several light sources that are usually LED, these products can also be used as projectors. Wall washers are lighting products instead of using projectors.

The advantages of wall washers include the high focus of LEDs, full coordination with the DMX system, high light efficiency and high efficiency, very low power consumption compared to ordinary lights and spotlights, the ability to install at different angles with the possibility of shadowing and Bright on the surface of the wall and the continuity of constant output light in the long term.

The main use of this product is to create lighting on walls, building facades, and creating light curtains on all kinds of surfaces, including walls, bridges, etc. Among other uses of wall washers, we can mention the manufacture of colored linear lights (such as flags). Wall washers are used for lighting large surfaces (especially walls). Wall washer is mostly used for lighting in new buildings. Of course, this element may be used in museums, galleries, and stores, or in places where there is a lighting subject that has a large area, and the lights and lighting used in the construction of wall washers are of LED type. LEDs are one of the most energy-efficient and suitable lamps that can be used for lighting. On this LED, a lens is used to adjust the angle of light radiation, which makes it possible to have more control over the lighting conditions. This angle usually covers 30 to 45 degrees. It should be noted that in special conditions and according to necessity, a lens with a different angle can be ordered.

The LEDs placed on the wall of the washers can be placed densely or at a small distance from each other, in which case they will provide more light. But the same wall washer can use less LEDs to have less light.
