LED Lighting Design

Improving Spaces

Whether it’s for a new build project or the refurbishment of existing lighting systems, Liht can offer a free LED lighting design service to ensure you obtain the required light levels where you need them, when you need them, whilst also saving you money.

Our bodies are affected by the natural rhythm of night and day through the dynamics of daylight setting our body clock and influencing our well-being, concentration and energy levels.

It is from our circadian rhythms, a 23 hour period daily cycle for the body, that we experience physical, mental and behavioural changes, primarily responding to light and darkness in our environment.

Good lighting therefore enhances the mood and desirability of spaces, contributing greatly to people’s sense of enjoyment of the space they are in.

Through the introduction of appropriate lighting levels and colour temperature, the natural levels of melatonin in our bodies can be reduced.  Melatonin is the hormone that drives our function to sleep, so with the right lighting levels drowsiness can be prevented in the daytime.

As we end the working day and rest it is important to consider the use of dimmer switches to lower the levels of light, so allowing the levels of melatonin to be increased.

Design for lighting

To achieve high quality implementation, the best first step is a detailed and appropriate lighting specification, so achieving the required levels of light.

Also through the use of occupancy censors, daylight censors and specific task lighting, the correct lighting levels will ensure that the occupancy comfort levels are maximised to create a positive internal environment.

Our clients have all realised improved lighting efficiency and reduced lighting costs of operation and maintenance through appropriate lighting design.

Building owners and managers therefore have the potential to add value, reduce costs, enhance performance and raise productivity through the application of good lighting.

What light levels are required?

Providing the correct levels of light in a room is critical to create a comfortable environment that increases concentration levels and productivity of the occupants.

The required levels of light depend upon the activity that requires lighting as well as to provide a safe working environment.
