Is circadian lighting design necessary?

Indoor lighting is always a critical component for all types of buildings. Recent trends of green building brings forward designs that utilises windows, sun roof or even large openings where natural sunlight can reach inside a building easily.

While this green movement serves to conserve lighting energy, it also directly benefits the people working within the building by exposing them to natural lighting. We can then explore the concept of cicadian lighting systems; the pros and cons of natural lighting to our body biological system.

Following the sun set and sun rise cycle, the natural light emitted from the sun varies in intensity and color temperature and we may have very strong dependency with the sun cycle. Circadian lighting design is meant to simulate the intensity and color temperature of the sun cycle to promote productivity at work and a relax atmosphere reaching the end of the day.

To achieve the respective intensity and color temperature, lighting industry have come out with tunable white LED where it can produce various color temperature via dimming of intensity and a control system that is capable of changing the intensity at real time. This is still a relatively new concept as the science and lighting technology have not yet merged together completely but companies in the United States are getting them installed improve productivity.

I feel that it would be necessary for circadian lighting design to advance further. With the flexibility and stability of LED lighting technology, there is the potential to provide more lighting design to benefit our human body and internal body clock. Gradually, the benefits may encourage more research into a better tunable bulb or white LED that have a wider and precise range for the color temperature.

Laser diodes - The next wave of LED lighting development?

Laser diodes to be the next LED lighting development - Is this possible and how feasible it is to our real life general lighting application?

Theoretically, if we place 2 mirrors on each side of the LED, the wide beam light throw effect from the LED will be forced to reflect internally within the 2 mirrors resulting in a more focused light beam.

This might mean that we need to create a light path for the LED in order to achieve the effect. This would be similar then to using fiber optic as a light guide.

All in all, can lasers replace LED Lighting? In my own opinion, i doubt so as general lighting requires a wide coverage at the lowest possible power input. Lasers will not be able to achieve an even wide coverage.

Project Lorong Halus wetlands - Outdoor lightings

Correct lighting techniques is extremely important when it comes to lighting up places like Lorong Halus Wetland where it can get very dim after sunset. 

Being the chosen lighting company by PUB, Singapore’s National Water Agency to light up Lorong Halus Wetland, we are extremely honoured to be recognised in our expertise in LED lighting technology and architectural design. In this project, we aimed to not only bring out the serenity and beauty of the reservoir but also create a flair of mystery liviness as night falls. 

With our landscape spotlights selectively placed in a desired angled it is able to create a balance and tailored lighting effect, evoking a sense of elegance and beauty to the reservoir overall atmosphere.

Our spot lights are not only quality assured but it is able to adjust to the correct lighting techniques to highlight the features and create the perfect amount of drama in the outdoor spaces but also energy-efficient, pocky friendly and definitely kinder to the planet.

With that, we also hope if we can also support your outdoor lightings at an extremely affordable price.

Tip for exterior lighting: A garden with appropriate lighting can often discouraged trespassers or thieves from entering or tempering with the property.

Rainbow Lighting fixture - beyond just lighting

I've always loved the multiple solid hues put together in a lighting fixture.

It adds a sense of permanent vibrancy to any living spaces. A standalone lighting fixture without the need to have lighting passing through it.

Let us know if you are keen to explore such fixture and we might just make one specially for your space. It will be a one and only lighting fixture !

LED Lighting Colour consistency; how to achieve it? (SDCM & MacAdam Ellipses)

Maintaining colour consistency in LED lightings and light source has always been a challenge.
It seems strange that we cannot maintain consistent lighting color tone for a machine made hardware.

After producing the LED chipsets, they are stored or group together in different bin. Each bin can be sorted by different methods, one being how close they are of the same colour tone.

With the variable nature of the colour produced by white light LEDs, one commonly used metric for expressing the extent of the colour difference within a batch (or bin) or LEDs is the number of SDCM (MacAdam) ellipses steps in the CIE colour space that the LEDs fall into.

In this situation as a manufacturer and LED Lighting OEM specialist, we can minimise inconsistent LED lighting colour tone by relying on SDCM (Standard deviation colour matching) or MacAdam Ellipse when selecting the LED chipset to be used in our lighting products.

If the chromaticity coordinates of a set of LEDs all fall within 1 SDCM (or a “1-step MacAdam ellipse”), most people would fail to see any difference in colour. If the colour variation is such that the variation in chromaticity extends to a zone that is twice as big (2 SDCM or a 2-step MacAdam ellipse), you will start to see some colour difference. A 2-step MacAdam ellipse is better than a 3-step zone, and so on.
