What Are the Different Types of LED Lighting Fixtures?

Led lighting fixtures are a collective name for LED lighting fixtures, which refer to appliances that can transmit, distribute and change the light distribution of LED light sources, including all parts and components required to fix and protect the LED light source except the LED light source, and connect to the power Necessary wiring accessories. With the further maturity of LED technology, LED will achieve more and better development in the field of room lighting design and development. The design of living room lighting in the 21st century will be based on the design of LED lighting. At the same time, it will fully reflect the energy-saving, healthy, artistic and humanistic lighting development trend, and become the leading lighting culture in the room. In the new century, LED lighting fixtures will illuminate everyone's room, change everyone's life, and become a great change in the development and design of lighting fixtures.

LED (Light Emitting Diode),

First, the LED is small

LED is basically a very small chip encapsulated in epoxy resin, so it is very small and very light.

Second, LED power consumption is low

The power consumption of LED lighting fixtures is quite low. Generally speaking, the working voltage of LED is 2-3.6V. The working current is 0.02-0.03A. This means that it consumes no more than 0.1W of power.

Third, the LED has a long service life

With the proper current and voltage, the life of the LED can reach 100,000 hours.

Fourth, high brightness, low heat

LED light-emitting diode manufacturers. LEDs use cold light-emitting technology, which generates much less heat than ordinary lighting fixtures.

Five, environmental protection

LEDs are made of non-toxic materials. Unlike mercury in fluorescent lamps, which can cause pollution, LEDs can also be recycled.

Six, durable

LED lighting fixtures are completely encapsulated in epoxy resin, which is stronger than light bulbs and fluorescent tubes. There are also no loose parts inside the lamp body. These characteristics make LED lighting fixtures difficult to damage.

High energy saving: energy-saving energy is environmentally friendly without pollution. DC drive, ultra-low power consumption (single tube 0.03-0.06 watts), electro-optical power conversion is close to 100%, and the same lighting effect saves more than 80% of energy than traditional light sources.

Long lifespan: LED light sources are called long-life lamps, which means lights that never go out. Solid cold light source, epoxy resin package, there is no loose part in the lamp body, there are no shortcomings such as easy to burn filament, thermal deposition, light decay, etc. The service life can reach 60,000 to 100,000 hours, which is 10 times longer than the traditional light source the above.

Multiple changes: LED light sources can use the three primary color principles of red, green, and blue. Under the control of computer technology, the three colors can be 256 gray levels and mixed arbitrarily to produce 256 × 256 × 256 = 16777216 colors, forming different lights The combination of colors can be changed in various ways to achieve a variety of dynamic changes and various images.

Environmental protection: better environmental protection benefits, no ultraviolet and infrared in the spectrum, no heat or radiation, little glare, and waste can be recycled, no pollution, no mercury element, cold light source, can be safely touched, belongs to the typical green Lighting source.

Gaoxinjian: Compared with the monotonous luminous effect of traditional light sources, LED light sources are low-voltage microelectronic products, which successfully integrate computer technology, network communication technology, image processing technology, embedded control technology, etc., so they are also digital information products. The "high-tech" technology of semiconductor optoelectronic devices has the features of online programming, unlimited upgrades, and flexibility.

With the continuous progress of large-scale integrated circuits and computer technology, LED displays are rapidly emerging as a new generation of display media. LED lighting fixtures have gradually expanded into the general lighting field and have become a beautiful landscape in modern cities. ^[1]

Cooling

At present, one of the biggest technical problems of LED lighting fixtures is the problem of heat dissipation. Poor heat dissipation causes LED driving power and electrolytic capacitors to become short boards for the further development of LED lighting fixtures. The cause of premature decay of LED light sources.

Only by expelling the heat as soon as possible can the cavity temperature in the LED luminaire be effectively reduced, the power supply can be protected from working in a persistent high temperature environment, and the LED light source can be prevented from premature aging due to long-term high temperature work.

Because the LED light source itself does not have infrared rays and ultraviolet rays, the LED light source itself does not have a radiation heat dissipation function, and the heat dissipation path of the LED lighting fixture can only derive heat through a heat sink closely combined with the LED lamp bead board. ^[2]

LED lamps, which can be combined with various light-colored LEDs to form various modules with soft illuminance.

In the context of rising global energy shortage concerns again, saving energy is an important issue facing us in the future. In the lighting field, the application of LED lighting products is attracting the attention of the world. LED is a new type of green light source product. It is bound to be the future development trend. The 21st century will enter the era of new-type lighting sources represented by LEDs.

China's LED industry started in the 1970s. After more than 30 years of development, China's LED industry has initially formed
