LED lights are the most advanced lighting products on the market today and are the latest technology used in the lighting industry. It has a wide range of applications and uses, especially in lighting.LED stands for Light Emitting Diode. Unlike fluorescent lights, LED lights are solid-state devices with no gases or other liquids that can evaporate and leak from the fixture, so they last longer than ordinary lights. In this article, I will try to give an overview of the classification and applications, and characteristics of LED lights.
Definition of LED Lights
There are many definitions of what exactly an LED light is, and there is no one exact definition. It can be said that it is a technology that uses light-emitting diodes as the light source, which has many advantages such as high luminous efficiency, instant-on, and low heat generation.
LED Lights have a wide range of uses
LED lights are the most popular today. Their popularity is increasing day by day and LED lights are used in a wide variety of areas. LED lights are an efficient product, as evidenced by the fact that they not only consume less energy but also tend to have a long lifespan.
This can be seen in the fact that they not only consume less energy but also tend to have a long lifespan.
Classification of LED Lights
LED lights have become the main light source. According to the classification of the occasions where LED lights are used, they are divided into indoor lighting fixtures and outdoor lighting fixtures. The main introduction here is indoor lighting. General room lighting fixtures include LED fluorescent lights, LED strip lights, LED wall lights, LED ceiling lights, LED pendant lights, LED downlights, LED panel lights, etc.
LED Fluorescent Lights
The LED Fluorescent Lights we all know, are now mainly divided into T8 and T5 so-called T8 or T5, which is a classification in the diameter.
LED Strip Light
The LED Strip Light is a form of hose was striped, belongs to the PVC material, generally installed in the ceiling along the inside of the edge or the backside of the backdrop wall molding, into a strip of light, the light irradiates the top or wall after the formation of a ribbon glow, soft and elegant.
LED Wall Light
The LED Wall Lights are mainly installed above the bed, in front of the dressing mirror, next to the door, in the hallway, kitchen, and other places for local lighting, etc. Wall lights are decorative lights installed on the wall. The installation position is slightly higher than the height of the human eye when standing. Can be used as auxiliary lighting, alternatively, in the chandelier, the ceiling light is the main lighting, both to save electricity and can adjust the atmosphere of the room.
LED Ceiling Light
The Ceiling Light is directly fixed on the ceiling lights and lanterns, suitable for installation in the interior of the lower floor height. The light source is the light bulb for incandescent lights and fluorescent lights. Ceiling lights with incandescent lights as the light source, most of them use milky white plastic cover or glass cover. Ceiling lights with fluorescent lights as the light source are mostly made of plexiglass, metal lattices for the cover. Diameter of about 200mm ceiling light suitable for use in the aisle, bathroom, and kitchen. The ceiling light with a diameter of about 400mm can be used in a room of about 16㎡.
LED Pendant Lights
The LED Pendant Lights are usually the protagonist of household lighting, and the varieties are more numerous. They can be divided into branch-shaped, flower-shaped, prototype, square-shaped, palace light type and pendant types according to the shape structure. According to the material of the components, there are metal components and plastic components; according to the nature of the bulb, can be divided into incandescent, fluorescent lights, small power candle lights; according to the size and volume, can be divided into large, medium and small. Commonly used in the living room and living room above 3m in height.
LED Downlight
The LED Downlight is a kind of indoor recessed lighting, covered with a cylindrical light shade on the light source, embedded in the ceiling, or with fixtures fixed in places that need local lighting, such as bedside, bookshelf, sofa, etc. In the ceiling to form a complementary to the main light embellishment and evenly distributed light source. And the movable downlight can be set at will according to the lighting needs, is easy to install, one light multi-purpose, flexible movement, easy to use, and does not occupy space.
LED Panel Light
The LED Panel Light is a high-grade indoor lighting fixture, its outer frame is made of aluminum alloy, the light source is LED light, LED panel light shape is generally divided into round panels and square panels, the whole light design is a beautiful and simple atmospheric luxury. LED panel light design is unique, light through the high light transmission rate of the light guide plate to form a uniform plane luminous effect, good uniformity of light, soft light, comfortable and not lose bright, can effectively relieve eye fatigue. LED panel light can also be anti-radiation, and will not stimulate the skin of pregnant women, the elderly, or children.
LED Lights Features
- LED light is emitted by light-emitting diodes, by applying forward voltage on the PN junction, its internal electrons, and holes compound, it will emit energy in the form of photons, which is a direct conversion of electrical energy into light energy, so it is decided that its conversion efficiency is high, and other lamps and lanterns under the same power, it emits the brightest light. the LED light-emitting principle determines that its service life is also longer than other lamps to be longer.
- LED lights are healthier than other ordinary lamps and lanterns, the light contains less ultraviolet and infrared light, producing less radiation. LED lights are green because it does not contain mercury and xenon and other harmful elements, do no physical harm to people, and facilitate recycling, ordinary lamps contain mercury and lead, and other elements, recycling more trouble.
- Although LED lights have many advantages, some places need to be noted. Such as LED lights because there is red, blue, and white light, therefore containing blue light components, blue light is harmful to the human eye and may cause retinal diseases to occur. But do not worry, most of the regular manufacturers of products blue light components are controlled within the safe range is not harmful to the human eye, substandard LED lamps and lanterns emitted light that may be harmful to the eyes, so we must buy regular brands of lamps and lanterns in the purchase, there is a very major parameter is the color temperature, color temperature of 4000K is the most suitable for us to read with.
Of course, there are more categories of LED lights than just these, I have only briefly introduced a few common indoor LED lights, if you want to know more about LED lights, you can read a book about lighting design, this book was written by a Japanese author writes, and the name of the book is “Practical Guide For Lighting Design”.
