LED panel

LED panel is a combination of two different words panel and LED. The panel is a rectangular, curved, or flat component that is placed generally on the wall, ceiling, or door. LED or Light Emitting Diode is a source of light that releases light when an electric current is passed through it. All together, we can say that an LED panel is a panel that consists of various LEDs inside it. It acts as a decorative component that can be mounted on the walls, ceilings of the home.

LED panels are commonly seen in restaurants, palaces, homes, hospitals, supermarkets, retail stores, offices, hotel lobbies, etc. LED panels are designed both for commercial and residential purposes.

The advantages of LEDs, such as less power consumption, low fluctuations, high efficiency, long life, no UV rays production, no inert gas present, and single directional oriented light, make it unique from other light sources. Thus, LEDs have replaced incandescent and fluorescent lights. LEDs are widely used today in bulbs and panels. It is easily available in various colors.

Here, we will discuss LED lights, uses of LED, selection of LED panel lights, top manufacturers of LED panels, types of LED panels, and more.

Let’s first discuss about LEDs before proceeding further.

What is LED?

LED is a semiconductor device that emits light in photons when an electric current is passed through its terminals. AS the name implies, it is a diode that conducts current in only one direction. Light is formed when the holes (positive charged) and electrons (negatively charged) combine. The process of producing light occurs in a solid-state semiconductor. Hence, LEDs are also known as solid-state devices.

Uses of LED

LEDs are used today in every field, ranging from LED bulbs at home to LED panels in restaurants or supermarkets. Let’s discuss the common uses of LED.

• Camera Flashes
  The flashes in the camera at the front or back of our Smartphone are used for photography effects even in dark light.
  We can say that LED flashes in the camera work as artificial lights.
• Image Inspection
  Automatic Imaging inspection in industries requires continuous and bright illumination, which LEDs can easily provide.
• Optical Fiber Communication
  Lights required in optical fiber communication needs to be radiant, directional, fast emission, and high efficiency. For this purpose, LEDs are best.
• Data Communication
  Light Fidelity is a technology that uses visible light derived from the LED for transmission. Data is transmitted by modulating the light intensity at one end and demodulating it at the other end. The use of LEDs can produce high data bandwidth, which helps in providing high-speed internet. It is also known as VLC (Visible Light Communication).
• Traffic Lights
  The LED lights are directional, which are visible even in the fog. It has a long life and requires less maintenance. Hence, LEDs are widely used as traffic lights.
• Medical devices
  LEDs are used in medical devices or achiness to treat various diseases, such as skincare, healing wounds, and dental. The use of LED in medicine is also known as Light Emitting Therapy.
• Decorative Lights
  LEDs are available in multiple colors and are used in decorating houses, buildings, offices, restaurants, etc., popularly during festivals and celebrations.

Selection of LED Panel Lights

LED panels are not very expensive. It is available in various price ranges starting from rupees 220. We can purchase the desired panel as per our requirements. The basic requirements for selecting LED panels include light intensity or brightness of the LED and the panel design. The panel design comes in various shapes, colors, and widths. We can select the appropriate design as per our requirements.

Now, let’s discuss the requirements for selecting the best-LED lights in a panel design.

• Lumens per Watt
  It refers to the output light. The higher the lumens, the higher will be the light output. It is given by:
  Lumens/Power
  It gives the efficiency of an LED. Hence, we should always consider the lumens per watt feature of an LED panel before purchasing it.
• Color temperature
  K refers to the temperature in Kelvin. It refers to the temperature scale of an LED ranging from 1000K to 10000K. The range can also extend beyond 10000K, which may include more shades of blue color. The specified range is 1000K for the blue color and 10000K for the red color. The specified color can be selected as per the color temperature value. According to the temperature, the light of an LED is categorized as natural white, warm white, and cool white.
  The range of the above three white lights is shown in the below table.
  
  

  White light	Color temperature range
  Natural white	4500K – 5500K
  Warm white	< 3000K
  Cool white	3000K – 4500K

  The temperature range scale of the LED lights in Kelvin is shown below:

Types of LED panels

The LED panels are categorized as:

• Recessed LED panel lights
• Surface Mounted LED panel lights

Recessed LED panel lights

It is the slimmer or thinnest LED panel available in the market. We can mount it easily in the ceiling. A cutout hole and the side springs help these LED panels to fit in the mounting surface. It is shown below:

It is perfect for homes because it can be directly built straight into the ceiling. It gives us a focus on light and elegant designs patterns. It is available in various price ranges starting from rupees 500 or $10.

Surface Mounted LED panel lights

Surface Mounted LED panel lights are thicker than the recessed LED panel lights. Unlike the recessed type, there is no need to cut a mounting hole on the counting surface to fit such

LED panels. It can be fitted by screwing a bracket onto the mounting surface.

It does not require any external reflector to direct light in a specific direction. It automatically directs the lights to a specific location.

Popular LED panel lights

The LED panel comes in various shapes and sizes. The common LED panels are square and circular shapes lights. As discussed, the choice of LED panel lights depends on the working hours, brightness adjustment ability, multipurpose, and lumen count. We can buy LED panels either online through an e-commerce website or various stores around us. These panels are also easily available.

Let’s discuss the popular LED panel lights.

• LED Fantasy light
  Its specifications are 0-10V, 40W, 5000K daylight white light, lumen count (4500), and working life hours of 50000. It saves around 80% of the light consumption as compared to other lights. It is shown below:
  
• Neox flat LED panel light
  Its specifications are 0-10V, 27W, 5000K, 120-277 voltage drop daylight white light, lumen count (3064), and working life hours of 81000. It is one of the slimmest LED panels available in the market. It provides 5-100% dimming. It is shown below:
  
• LED flat panel light
  Its specifications are 0-10V, 40W, 4000K, 120-277 voltage drop bright white light, lumen count (4826), and working life hours of 40000. It saves around 82% of the light consumption as compared to other lights. It is shown below:
  

Similarly, there are other types of LED panel depending on the working hours, lumen count, percentage power consumption, and the dimming adjustment ability.

Advantages of LED Panel

The advantages of LED panel lights are as follows:

• Flexible design
  LED panels are available in various shades and design. We can select the appropriate pane as per our house contrast.
• Environment friendly and long life
  LED panel comprises LEDs as a source of light. Hence, these panels are environmentally friendly and have a long life.
• Ultra slim with various color options
  The width of the LED panel is small and has sleek designs.
• Good heat dissipation
  The frame of these panels is made of aluminum and includes a heat sink system. It prevents the device from heat dissipation ensuring high level of safety.
• Low power consumption and shock-resistant
  LED panels can be used over a long duration due to their very low power consumption. Hence, it is widely used in restaurants, hotels, supermarkets, etc. It is also shock-resistant due to its good quality materials.
• High brightness and adjustment control options
  The LED panels are made of high-quality metals and alloys. LEDs have high efficiency, due to which their light output has high intensity and brightness. We can also control the brightness level of an LED as per our requirements.

Disadvantages of LED panel

The disadvantages of LED panel lights are as follows:

• Low output power

As compared to LED bulbs, LED panels produce low output power. For example, an 8 Watts LED bulb and 12 Watts LED panel light produce the same output power. It means that we get around 60-70% light output from the LED panel lights, while around 90% light output from the LED bulbs.

• Big fixture

The greater required power output of an LED, the bigger the LED comes into play.
