Photometric Lighting Software

[Harcourt Ordonez]

Photometryis the science of measuring the perceived power of a source of light. A photometric plan, also known as a photometric analysis or photometric lighting layout, is a way to view a proposed lighting solution and the foot-candles that can be expected to be achieved before installation. Simply put it is a computer simulation of light.

Photometric studies can digitally simulate both indoor and outdoor lighting designs. A photometric study can replicate the position, intensity, and color of any lighting design. The results show you the light and shadow distribution along with the contrast between light and dark zones in the space provided.

A photometric plan utilizes this photometric software to create an authentic visualization of what the proposed lighting layout will be based on the entered property blueprint. A photometric plan ensures that the proposed lighting layout aligns perfectly with your goals and allows you to digitally review your design and make adjustments as necessary, before installation.

Photometry may be a complicated, technical science, but lighting designers have made it simple in its application. In any large or Commercial, Industrial, or Retail spaces that require major lighting, a photometric plan will serve to be advantageous in six ways to the clients, the architects, and lighting designers through:

It is recommended that every customer require a photometric layout from their contractor or supplier. A photometric plan is particularly necessary anytime that your lighting project must adhere to specific codes, is being used for safety purposes, or on large properties. Some examples include:

Warehouses: Having a photometric analysis done before the construction of a warehouse will provide you with a comprehensive plan that gives you the best lighting solutions before you buy LED floodlights and hazardous lighting systems. A photometric lighting plan will allow you to maintain a consistent lighting level throughout your warehouse.

Retail Spaces: A photometric analysis of any retail space such as a grocery store, department store, and convenience store can set a special lighting arrangement for new product areas by prioritizing the illumination of that area. A photometric lighting plan will allow you to maintain uniform lighting across the space so that the products are well highlighted and easily identifiable by customers.

Parking: A photometric analysis of a commercial parking space will allow you to comply with the required codes for the minimum, maximum, and average light levels for the space. A photometric plan will also address all safety concerns and eliminates light trespass.

A lighting system that is too dim can be disappointing. That is why the proposed lighting system should be planned, visualized and mathematically calculated to meet the requirements and local lighting codes.

In the modern world, where precision and accuracy hold paramount importance, photometric plans play a vital role in a variety of fields. Whether it's designing efficient lighting systems, illuminating sports fields for night-time games, or conducting biomedical imaging, photometric plans are essential tools that ensure optimal performance. This article aims to explore the concept of a photometric plan, its significance, and its applications in different industries.

Photometry is the scientific measurement of light and its properties. It involves quantifying the intensity of light, its distribution, and its interaction with various surfaces. The fundamental unit used in photometry is the candela, which represents the luminous intensity of a light source. Other units like lumens and lux are used to measure the total light output and illuminance, respectively.

A photometric plan is a detailed strategy outlining how light sources will be placed and utilized to achieve specific objectives. It considers factors such as brightness, direction, and color to achieve the desired lighting effect. These plans are developed based on the specific needs of the application, ensuring efficient use of resources and adherence to industry standards.

In architectural and interior design, photometric plans are indispensable. They allow designers to create lighting setups that enhance the aesthetics of a space while ensuring practical functionality. By simulating the behavior of light in different scenarios, designers can optimize lighting layouts for maximum comfort and efficiency.

Objective methods of measuring light have been around for centuries, but standardizing and archiving this data has only been a priority in the last few decades. Ask a lighting designer about what the industry was like before the IESNA started formatting fixture data, and the answer might not be pleasant. With thousands of fixtures on the market, it is impossible for an individual design firm to produce and maintain so much data. They need help from an organization dedicated to building photometric maps, and the IESNA is the organization that stepped up.

It goes without saying that if a client could see what the fixtures could do before being installed, it would help that client make a decision. It also goes without saying that the ability to diagram a project would greatly reduce guesswork and wasted effort on the part of the lighting designer. Photometric data makes both of these possible.

Using photometric diagrams, which are generated in special imaging programs, a lighting designer can create a 3D model of a set of fixtures. Each fixture uses the IES data to accurately display how it would appear in a parking lot, an industrial complex, a commercial center, a large building, a residential property, a museum, a gallery, or anywhere else a collection of fixtures might be needed to light an area.

Take, for example LED lighting. LED lighting is quickly replacing high pressure discharge lamps and metal halides in larger scale applications like parking lot lighting. However, there is a significant difference between LED and discharge lamp luminous intensity. Whereas discharge lamps and metal halides produce radiant illumination, or illumination that travels in all directions like a globe, LED fixtures produce strong directional illumination and do not emit in a radiant pattern. This makes for additional challenges and additional benefits when installing LED fixtures, but most importantly, it has a major effect on how photometric diagrams are produced when using LED technology.

Accounting for these subtle (or not so subtle) differences is what makes photometric concepts and drawings so important for a lighting project of any size. But it is a must for projects that demand precise lighting for security or efficiency reasons. And an experienced lighting firm will be able to provide cutting edge photometric concepts for its clients.

The Elements Of Lighting Design

If the goal of a lighting design project is to produce even coverage over a large area, then the only proper approach is with photometric diagramming. Read more...

Super beginner here.

I've been grinding my gears over this for some hours now, and I cant seem to get it to work.

I'm working on a task where I'm supposed to add materials and lighting to a scene, and indoor lighting should only consist of photometric lights. I have added a photometric light, but what ever I do the results are horrible in render.

To much lumen and the render turns white. To little lumen the light is non exisiting (even though it looks perfect in high quality camera view with "scene lighting" activated). Something inbetween, you say? Nope, not working.
