Advantages of LED Functional Lamp

 

1

Long Life

Long lifetime stands out as the number one benefit of LED functional lamp. LED bulbs and diodes have an outstanding operational life time expectation of up to 100 hours. This is 11 years of continuous operation, or 22 years of 50 percent operation. If you leave the LED fixture on for eight hours per day, it would take about 20 years before you'd have to replace the LED bulb.

2

Energy Efficiency

Today's most efficient way of illumination and lighting, with an estimated energy efficiency of 80-90 percent when compared to traditional lighting and conventional light bulbs. This means that about 80 percent of the electrical energy is converted to light, while 20 percent is lost and converted into other forms of energy such as heat.

3

Ecologically Friendly

LED functional lamps are free of toxic chemicals.LED functional lamps contain no toxic materials and are 100 percent recyclable, and will help to reduce your carbon footprint by up to a third.

4

Durable Quality

LEDs are extremely durable and are built with sturdy components that are highly rugged and can withstand even the roughest conditions.

5

Zero UV Emissions

LED illumination produces little infrared light and close to no UV emissions. Because of this, LED lighting is highly suitable not only for goods and materials that are sensitive to heat due to the benefit of little radiated heat emission, but also for illumination of UV--sensitive objects or materials such as in museums, art galleries, archeological sites, etc.

6

Design Flexibility

LEDs can be combined in any shape to produce highly efficient illumination. Individual LEDs can be dimmed, resulting in a dynamic control of light, color, and distribution. Well-designed LED illumination systems can achieve fantastic lighting effects, not only for the eye, but also for the mood and the mind.

7

Light Dispersement

LED is designed to focus its light and can be directed to a specific location without the use of an external reflector, achieving a higher application efficiency than conventional lighting. Well-designed LED illumination systems are able to deliver light more efficiently to the desired location.

8

Compatible with Smart Home Applications

One of the most outstanding features of LED functional lamp is that they are compatible with smartphones. You can connect them to your phone through Wi-Fi or Bluetooth and operate them efficiently. Such facilities are far beyond imagination in using traditional light bulbs.

Application of LED Functional Lamp
 

Office and Retail Stores

Lighting is one of the most vital components of successful retail space for supermarkets, stores, shopping centres and other commercial entities.That’s why many business owners have adopted LED functional lamps, as they assist in saving up to 80% on power costs compared to traditional lighting sources. LED lights offer bright illumination, making it easy to project spotlights onto specific items within a display to highlight the product.

 

Warehouses and Factories

Warehouses involve a large number of physical operations either performed directly by the staff or using machines such as forklifts. To guarantee safe operations and reduce the rate of accidents and operation downtime, warehouses benefit from bright LED functional lamps to illuminate the workspace.

 

Healthcare

Lightning applications in hospitals are wide and varied, as each space has a unique purpose with a specific lighting requirement. There are different requirements for treatment areas, observation areas, ward areas, waiting and circulation spaces, and operation theatres, each to serve the purpose of the area.Because of these broad and varied lighting applications, healthcare facilities use LED functional lamps to illuminate hospitals depending on the specific design criteria required.

 

LED Signals and Indicators

Traffic lights, exit signs and car lights all use LED functional lamps. LED lighting has proved to be a perfect solution for exit signs due to its energy efficiency and durability.The long lifespan of LED functional lamps, their ability to turn on and off rapidly and their high output for easy visibility in daylight, make LED lights a perfect solution for vehicle brake lights, as well as in headlights.

LED Classic Wall Lamp

Street Lights

A majority of street lights illuminating the dark streets and highways at night are actually LED functional lamps. Municipalities and governments realized that the initial upfront cost for LED lighting is justified by the savings made in the operational costs over the lifespan of the lights

 

Showrooms

In this era of competition, showrooms constantly look for ways to lower operational costs and gain the highest returns on their investment. Showroom owners use LED functional lamp to save costs and provide both general and specific lighting to their spaces.

 

Parking and Garages

Parking lots, car dealerships and garages all need high lumen outputs to properly operate and LED functional lamps can easily provide high illumination levels in these spaces to ensure comfortable and safe operation, specifically where mechanics require bright lights for repairing detailed features in vehicles.

 

Theatres

Proper lighting systems allow theatre managers to control the mood, enhance the performance and to focus the audience’s attention on specific spaces or scenes.With traditional lighting, these systems tend to be heavy and complicated and emit large quantities of heat, however, when compared to traditional stage lighting fixtures, LED functional lamps are cooler, last for longer, and the fixtures are lighter.

 

 

Types of LED Functional Lamp

TYPE A LED LAMP: LED Lamp with Integrated Driver – Works with Existing or New Linear Fluorescent Lamp Ballast

Type A Lamps are designed with an internal driver that allows them to work with linear fluorescent ballasts. Compatibility between tubes and ballasts should be evaluated to ensure good system performance.

 

TYPE B LED LAMP: Double-Ended Ballast Bypass LED Tubes - Wired to Main Incoming Power Supply

Type B LED Lamps also have an internal driver. A Type B LED Lamp offers the simplest total system with respect to number of components — retrofitting involves wiring directly to main voltage, bypassing the ballast. This removes any compatibility issues and eliminates maintenance costs associated with ballast replacements.

 

TYPE C LED LAMPS: LED Tubes with Remote Driver

Type C LED Lamps operate off of a remote LED driver, instead of an integrated driver. Like the Type B LED Lamp, Type C LED Lamps require electrical modification to the existing light fixture, but the low-voltage outputs of the driver are connected to the sockets instead of the main voltage.

Components of LED Functional Lamp
 

LED Chips

LED chips do the heavy lifting of creating light. They look like small yellow circles attached to a piece of metal, also known as a printed circuit board or PCB.

 

Heat Sink

All light sources produce heat. Older bulbs radiated heat into their immediate environment, making the bulb hot to the touch. In LED bulbs, a heat sink conducts the heat away from the light emitting diodes to keep the entire unit cool. The heat sink is composed of a piece of metal the LED chip sits on that provides a path for heat to leave the light source.

 

Circuit Board/Driver

The terms circuit board and driver are generally interchangeable and refer to the “brain” of the bulb. This component takes energy from the electrical socket and tells the LEDs what function to perform, like turning on and off, dimming or changing color. LED drivers are similar to ballasts in fluorescent lamps. They also protect LED bulbs from voltage or current fluctuations, which could damage the unit.

 

Housing

The circuit board of an LED heats up when energy passes through it, creating the necessity for a heat-conducting component. A housing made of material with high thermal conductivity, typically aluminum, makes up the lower section of the bulb where it connects to the base. This housing absorbs the heat from the circuit board, so it will become warm to the touch — but not as hot as halogen, incandescent or fluorescent lighting.

 

Base

The base of a light bulb is the part that screws into a fixture or socket. Because LEDs are designed as direct replacements for existing light bulbs, they are available in a wide selection of base types, including all those you recognize from more traditional bulbs.

 

Lens/Optics

Due to the brightness of LEDs, a covering component is added to evenly distribute the light. This cover is called a lens on single-direction lamps and optics on omni-directional lamps. These components are typically made of shatter-resistant plastic and help give LEDs the familiar look and feel of more traditional bulbs.
