ABCs Of LED Lighting Design

Some lamps were mainly used in shop windows and shops, in exhibitions and in museums, but today, especially the halogens and the energy-saving IRC halogen lamps are an excellent solution for lighting work and study tables. Halogen lamps are available in a wide variety of shapes and powers. It is possible to divide them into two large families:

They are low voltage lamps, so they need a transformer to work. The acronym IRC stands for Infrared coating which means that they have a reflector that reports part of the heat on the bulb itself, therefore they require less energy to have the bulb at the ideal operating temperature.

When compared with traditional halogen lamps they consume less energy, disperse less heat, last longer, have a greater luminous flux over time. Energy-saving halogen lamps replace traditional incandescent lamps where localized light, frequent re-ignition, discontinuous use and immediate availability of light are needed.

Halogen lamps have a luminous efficacy (around 15-25 lumens/watt) which is almost twice the traditional ones. They last twice as long as traditional ones (the average duration is around 2,000 hours); last generation ones (IRC) last more than 4000 hours. The decay of the luminous flux as a function of the hours of life is practically negligible and there is no blackening of the bulb.

They emit white light with excellent color rendering. The luminous flux can be adjusted using a simple variator. Those at low voltage need a transformer to function.
They have very small dimensions and are available in a remarkable variety of shapes and powers associated with LED Lighting Design.

They are recommended where you need localized and decorative lighting, immediate availability of light, discontinuous use and frequent switching on and off. They do not contain toxic and dangerous substances so they can be disposed of as unsorted waste.

They belong to the family of gas discharge lamps such as mercury vapor lamps, sodium vapor lamps and halide vapor lamps which, however, are scarcely used in the home. Fluorescent lamps consist of a glass tube internally coated with a layer of special fluorescent powders, which contains mercury vapor at low pressure as shown in LED Lighting Design.

At the extremities there are two electrodes which, at the passage of the current they were a discharge to which the emission of light radiation is associated. To power these lamps it is necessary to use a reactor, which serves to limit the current value.

Guide To Stage Lighting Sydney

Luminous intensity expressed in Candles (cd). Indicates the intensity of the light radiated by a lamp in a given direction. Duration expressed in hours indicates the number of hours of operation after which, in a given batch of lamps and in well-defined test conditions, 50% of the lamps cease to function.

Color temperature expressed in degrees Kelvin (° K). Indicates the tone of the light emitted by a lamp. On the market we find lamps with different shades of white, warm with shades of yellow, neutral, and cold with shades of blue used in Stage Lighting Sydney.

Color rendering index (Ra). It varies between 0 and 100, and indicates to what extent the colors perceived under an artificial lighting approach the real colors. The closer this index is to 100, the more the light source allows the appreciation of color shades.

Luminous efficiency (lm/W). It gives an idea of the amount of electricity absorbed transformed into light. It represents the ratio between the luminous flux emitted by the lamp (expressed in Lumen) and the electric power that feeds it (expressed in Watts). It is indicated with the lm/W symbol. It is a very important parameter for choosing the most suitable light source to save energy for Stage Lighting Sydney.

Expresses the amount of light energy emitted by the lamp in the unit of time. Illumination expressed in Lux (lx). Indicates the amount of luminous flux that hits a unit of surface. A Lumen on an area of 1m2 corresponds to 1Lux.

Replacing halogen lamps with LEDs

Replacing halogen or incandescent lamps with LED ones, represents a very useful solution that allows to obtain different advantages in terms of energy saving. The bulbs are primarily electrical devices designed to produce light and are classified according to the voltage (V) and the power absorbed by the network, expressed in Watts (W). The lumens instead express the degree of brightness emitted by the lamp.

The ratio between the visible light energy emitted and the absorbed electrical energy is defined as luminous efficiency. Part of the energy produced is lost, dissipated as heat or emitted light not visible to the human eye (eg infrared or ultraviolet light).

Based on the type of technology used, we mainly distinguish 4 types of bulbs: incandescent, fluorescent, halogen and LED. Let’s see the main characteristics of the various types of lamps and why it is good to replace the halogen lamps with LEDs.

5 Tips For Installing LED Stadium Lighting

LED stadium lights are the go-to lighting solution for many sports applications. The quality light emitted by LED stadium lighting fixtures enhances fan experience and increases safety. Further, LEDs have longer lifespan, offer incredible energy savings amongst other benefits.

To really enjoy all the benefits of LED stadium lighting, the installation project has to be top-notch. Anything less than that will only hurt your efforts greatly. As a guide, here is an overview of the top five tips of success when it comes to LED sports lights installation.

1. Customize Your Solution

Let no one lie to you: there’s no one-size-fits-all solution when it comes to LED installation. Each space offers unique requirements based on the existence (or lack thereof) of natural light, the specific project done, the existing lighting fixtures on the ground and other important factors. How you install LED stadium lights in an institution will differ from a manufacturing firm. A good grasp of the project will plunge you in the right direction.

2. Review Your Challenges

Some spaces present more challenges than others. A good example is damp environments. Even with proper air conditioning and dehumidification systems in place, the installation project will require light fixtures that are IP rated for a damp location. You’ll also need to prevent glare to enhance safety and navigability.

3. Maximize Existing Infrastructure

LED stadium installation projects aren’t an excuse to do away with existing infrastructure. You can get creative during the installation project even if it’s a one-on-one replacement job. Find ways to compliment your LED directional light with other sources so as to achieve a perfect spread of light.

4. Bundle Multiple Projects

It is amazing just how much you can save by combining all your lighting problems into one huge project. And, you know, if you looked around hard enough, you will come with a long list of improvements that can potentially save you money in energy costs.

5. Optimize Your Lighting Control Systems

Finally, to derive maximum value from your LED stadium lighting, you want to design systems of reducing the lighting power density of your space. One such system works by dimming your LEDs and hence increasing light output over the course of time. Others have additional features like occupancy detection and zoned control.

Bottom-line

Before you pick up your tools in readiness for your LED stadium light installation project, consider these five tips to make thing seamless, affordable and less stressful. Why do an average job when you can stretch a little and make the project worth the while?

What Makes A Good LED Lighting Design?

Long lasting, energy efficient, and environmentally friendly, LED lighting is one of the best choices for modern homes. Besides, considering that incandescent bulbs are slowly being phased out, every homeowner will need to make the switch. With today’s diverse LED lighting choices, LED light can find a home in just any room, whether lighting your kitchen cabinets or striking a chandelier or brightening up the exterior of your house. But which LED lighting design should you choose for your home? Well, a good LED light should have a few design features, including but not limited to:

1. Wavelength

To get the color of lighting that you really want, you to need focus on the wavelength specifications. This will help determine whether you are going to get yellow-green light or true green.

2. LED efficiency

The efficiency of light is generally measured in lumens per watts which refer to the total lumens produced divided by the total amount of power consumed. As a rule, most customers tend to aim for 100 lumens per watts from a whole system including any loses due to lensing, heat, power conversion and light guides.

3. LED Color Temperature

Although you may know how bright you want your LED to be, the color temperature may be a lot less obvious. Color temperature refers to the measure of how warm or cool the light appears. Since the color of light measured in kelvins can officially describe the appearance of a metal burning at various high temperatures, this can be a bit deceptive. The light temperature that you choose should, therefore, depend on the type of industrial application or consumer you are building.

4. Visibility

Visibility depends on the viewing angle of the LED and how well your eyes perceive the selected color together with the lumen output. For instance, green LED, run at 2mW may appear as bright as Red LED run at 20Ma.

5. Viewing angle

The viewing angle is the distance from the center of the beam of light before it losses half of its intensity. Although the common values are 120 and 45 degrees, a light pipe or another light guide will perhaps need a tighter viewing angle of 15 degrees or less.

Bottom-line

Purchasing the right LED light is quite different from buying normal incandescent bulbs. So, before you go shopping, there are a few factors that you need to take into considerations. The above highlighted are the major things that make a good LED lighting design. If you want your next LED lighting design to be optimized for impact then you need to keep them in mind.
