Tech Talk Tuesday : Understanding Different Light Distributions

There are several different light distribution types and each one can have a drastically different effect on your space. The different types are as follows:

-Direct: 90-100% Downward
“Maximum light output directed downward for efficient task lighting. Provides high illumination levels with minimal energy consumption”

-Direct-Indirect: 40% Up, 60% Down
“Balanced distribution combining task lighting benefits with ambient ceiling reflection for optimal visual comfort”

-Semi-Indirect: 60-90% Up, 10-40% Down
“Primarily upward distribution with minimal downward component, reducing glare while maintaining some direct illumination”

-Indirect: 90-100% Upward
“Light is directed upward to reflect off the ceiling, creating soft, diffuse illumination with minimal shadows and glare”

-Semi-Direct: 60-90% Down, 10-40% Up
“Primarily downward distribution with some upward component to reduce contrast and provide ceiling illumination”

-Diffuse/General Diffuse: Equal in all directions
“Uniform light distribution in all directions, creating even illumination with minimal directionality”

Knowing which type of light distribution you want will allow you to massively enhance your lighting systems.

Tech Talk Tuesday : Understanding Light Bulbs

With such a wide range of light bulb shapes and types it can feel overwhelming when making a decision. By being able to understand these light bulb codes, picking the right bulb for your fixture will be easy.

Type A Light Bulbs : A15, A19, A21 & A25
These bulbs are typically used for standard household lighting and are good for a variety of household fixtures. Usually, they are compatible with medium screw bases (E26 and E27) or the candelabra base (E12). The standard lamp bulb size is A19 however traditional incandescent A19s are being replaced with LED bulbs due to their improved energy efficiency.

Type B and C Light Bulbs : B10, C7, C9, C15, CA10
These bulbs resemble a candle flame and, not surprisingly, are commonly referred to as “candle bulbs”. They are longer and have a tip at the end of the bulb. They are usually found in decorative lighting fixtures. The base types that are the most prevalent are the E26 and E27 medium screw in bases, the E12 candelabra base and the E17 base.

Type BR Light Bulbs : BR20/R20, BR30, BR40
These bulbs are reflectors and bulged reflectors. They can be found in the home in outdoor floodlights or in recessed lighting. BR30 and R20 bulbs are the most common and they usually connect with the E26 or E27 bases.

Type PAR Light Bulbs : PAR16, PAR20, PAR30, PAR36, PAR28
These bulbs are parabolic aluminized reflectors and are most commonly used in outdoor lighting, similar to BR lights. PAR lights will create a more concentrated beam where as a BAR light will provide a wider ‘wash’. Typically the base types are the E26, the E27 and the G53 screw pin base.

Type MR Light Bulbs : MR11, MR16
These bulbs are multifaceted reflectors and are typically used in track lights, recessed lights, desks and display cases. They project a focused beam of focused light in a specific direction and are available in a wide range of colors. They are also a great choice for landscaping applications due to their low voltage wiring systems. The most common base type of low-voltage AC/DC systems is the GX5.3 bi-pin or GZ4 bi-pin. The GU-10 bi-pin is most common for 120-volt systems.

Type LFL and T Light Bulbs : T: T7, T8, T10, T12, T14; LFL: T5, T8, T12
These bulbs are tubular and linear fluorescent lights. A T5 Tube has a diameter of 5/8 of an inch, a T8 has a diameter of 8/8 of an inch etc. LED replacements are becoming more popular due to their increased efficiency. T group lights most commonly connect with E26 and E27 medium screw bases, E12 candelabra bases, E17 bases, BA15D bayonet bases or the G13 bi-pin base.

Type G Light Bulbs : G11, G14, G16/G50, G60, G25, G80, G30
The bulbs are globe lights. They are used mostly for aesthetic purposes and are most commonly found in vintage styles (identifiable by the antique-looking filament in the center). They typically connect with E26 and E27 medium screw bases as well as E12 candelabra bases.

Tech Talk Tuesday : The Science Behind LEDs

LEDs or Light Emitting Diodes are a revolutionary lighting technology. Created in the mid-20th century “primarily for indicator lights due to their low power consumption and long lifespan.” (1) LEDs have since transformed the lighting industry but what’s the science behind making them work?

Electroluminescence is the core principle behind LED Technology. Visible light is produced when electrons are energized from an electric current passing through a semiconductor material and recombine with an absence of electrons. The light color will be influenced by the “energy bandgap of the semiconductor used in the diode.” (1)

Depending on the material and chemical composition that is used, a wide range of colors can be created, for example:

- Gallium nitride – Blue or Violet light
- Gallium phosphide – Green hues

White LEDs have also been developed and are typically created by “combining blue LEDs with phosphor coatings that convert some of the blue light into other colors, resulting in a more balanced white light suitable for various applications.” (1)

Tech Talk Tuesday : How can daylight sensors optimize your lighting system?

In a similar vein to the Tech Talk Tuesday discussion last week, this week we will be discussing how daylight sensors can contribute to energy savings and optimize your lighting system. “Both the Electric Power Research Institute (EPRI) and American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) estimate an average 30% savings from this technology in generic assessments for commercial buildings” (1). However, that number can get as high as 60%.

Daylight sensors have some key features including detecting a wide range of light levels from Low (3-300 lux) to High (30-3000 Lux) and Direct Sun (300-3000 Lux), they are also available in wired or wireless options.

Daylight harvesting “adjusts artificial lighting based on the natural light available in a space. Using photocell sensors, the system detects ambient daylight and either dims or switches off lights, making it particularly useful in areas with abundant natural light.” (2). This method can reduce energy consumption by 20-60%. “Natural light has been linked to improved mood, increased alertness, and reduced eye strain. A well-designed system ensures smooth transitions between natural and artificial light, avoiding discomfort or distractions…Additionally, utility rebates and U.S. tax incentives…further enhance the financial benefits.” (2)

If you’re looking to make your lighting system even more efficient, daylight sensors may be the next step you’ve been looking for.

Tech Talk Tuesday : How can the use of occupancy sensors result in energy savings?

It’s no secret that LEDs are leading the way in terms of energy efficient light sources, however you can make your lighting even more efficient with the use of occupancy sensors. With energy savings rates of 15-90% (depending on the room type), you could be saving a whole lot.

There are a few different types of sensors that can be used and, depending on the application, some are better suited than others:

PIR (Passive Infrared) sensors are wireless and are “typically used in small, enclosed spaces to detect major motions” (1), usually have a nominal limit of 15 feet and are not particularly effective at picking up small movements. The sensor also requires that there are no objects in the way of it as it needs a direct line of sight to detect motion. They are passive and as a result require very little power.

Ultrasonic sensors are wired and “detect occupancy by constantly emitting high-frequency sound energy signals that can move throughout a room and around objects in a room”. They are sensitive enough to pick up on small movements (typing or page turning). Ultrasonic sensors actively send out signals and therefore require more power.

Bluetooth sensors are wireless and “detect the presence of people or objects by transmitting a signal between a transmitter and a receiver.” (1) In a parking garage a car would block the signal and indicate to the sensor that the space is being occupied. They can be used with wireless occupancy sensors however in parking applications the biggest energy savings come from people being detected, not cars.

Microphonic sensors are wireless and “detect presence by constantly monitoring for sound. When sounds are detected, the sensors determine the space is occupied. This is a passive sensor technology.” (1)

Video Image sensors are wired and “use a camera and video analytics to determine whether or not a space is occupied”(1). The sensor is always working however they are very application specific and require a lot of power (so can only be used in wired applications)

Dual technology sensors are wired and “use PIR sensors together with another sensor technology, ultrasonic (active) or microphonic (passive).” (1) Light is only activated when both of the sensors detect occupants. They can produce more “false off” conditions.

So, depending on what applications you are using your lighting systems for, occupancy sensors may be just what you need to increase your energy savings.
