Lighthouse Consulting, LLC is you’re lighting design specialist. Our trained staff has over forty years of lighting design and application experience. We offer design services for interior and exterior applications in commercial and industrial facilities. Through lighting design, we
will enhance the built environment through our understanding of the integration
of light and space. Our expertise is in combining creativity with quality design
and technical skill. We will work with your architect, interior designers or
engineer as a member of the design team. We provide a full scope of services for
interior, exterior and day lighting applications.
Lighting is one of the most important elements of a pleasant architectural design. Whether it is to create a harmonious workplace or to showcase a modern design, modern lighting is more than simply illuminating an area. We strive to create innovative solutions combining the best of existing technology with state of the art lighting sources.
Lighting
Energy Evaluation – Energy Savings verses Light Quality Artificial lighting in commercial, industrial, municipal and retail buildings are a major and conspicuous consumer of electrical energy. In addition, air conditioning consumes energy and may be required to remove the heat generated by lamps. Energy consumption is measured as the product of power input (kilowatts) and the period of use (hours). To reduce it both input and hours of use must be controlled. Lowering general illumination
levels, adopting selective lighting standards, and replacing inefficient sources
may reduce power input. Hours of use can be reduced through sensible switching
arrangements and automatic light control that takes advantage of available
daylight and space occupancy. One of the most important considerations in lighting system design is the specification of the required illuminance level. The magnitude of this level and the method by which it is achieved strongly influence the electrical power input (kilowatts) needed to operate the system. Of equal importance is lighting quality, to which a number of separate factors contribute: visibility, discomfort glare, surface brightness ratios, the directional flow of light for revealing human facial features and the textured surfaces of the building interior. ESI designs to date have been more than adequate in lighting quality, and have in many cases been regarded as providing a more interesting, luminous environment than traditional monotonous, uniform illuminance schemes. Comparison
of Lamp Characteristics One of the most effective means of decreasing power input is to choose efficient lamps. The efficacies of common lamps are described in units of lumens per watt; typical values include incandescent 11 to 22, mercury vapor 18 to 65, fluorescent 40 to 80, metal halide 75 to 100 and high pressure sodium 85 to 130. Efficacy alone, however, does not determine the best and most economic lamp choice. For example, High Intensity Discharge (HID) lamps can require a "warm-up" period of several minutes before they reach full light output, and this may be a disadvantage if frequent switching is required. Lamp life, lumen depreciation, color rendering, glare, and the total light distribution from the luminaire must also be considered. There is some evidence that improved visual clarity with the better color-rendering lamps can compensate for their lower intensity output. Reduction in the connected load can be achieved by choosing luminaries that direct most of their light below the horizontal plane in the direction of the work plane. Limiting values of Visual Comfort Probability (VCP), as given in the IES Lighting Handbook, 3 should be followed to avoid problems of discomfort glare. Management
