Samsung’s new Q-series LED linear modules offer superior efficacy to improve premium indoor lighting

Samsung Electronics Co., Ltd. today announced the launch of the “Q-series,” a new line-up of LED linear modules for use in premium indoor luminaire applications where an exceptionally high level of light efficacy* is required.

The Q-series features 200 lumens per watt (lm/W) of light efficacy, which is the highest efficacy level among current LED linear modules. The new modules are the first to incorporate the LM301B, Samsung’s recently announced mid-power LED package.

This allows LED lighting fixtures using the new modules to reach more than 150lm/W, enabled through an optical efficiency level of approximately 86 percent and LED driver efficiency of about 88 percent. The Q-series’ performance levels are ideally suited to meet DLC** Premium technical standards, which require higher efficacy and lumen maintenance specifications than the DLC Standard classification.

The new Q-series modules come in one-, two- and four-foot sizes, and can be combined linearly to achieve any desired length. There are two sets of modules: Q-series modules for the North American market are UL certified, while those for the European market have CE certification.

With the addition of the premium Q-series line-up, Samsung now offers five families of LED lighting modules (Q-, H-, M-, S- and V-series) to meet most indoor LED lighting needs. The Q-series has the same form factor as Samsung’s other modules for easy retrofitting with existing LED luminaires and is now available through Samsung’s worldwide LED sales network.

Samsung’s Q-series line-up includes:

    I reserve judgement on the general utility of this lighting, as in the absence of other data “premium” seems to have a slightly unusual meaning here: luminous efficiency rather than good-quality white light (conventionally specified by the “Colour Rendering Index”).
    The trend for premium-quality lighting is to have CRI greater than 95; this requires a significant proportion of the light to be in the less sensitive ends of the sepctrum; thus ultra-high luminous efficiency lamps will typically
    Ultra-high luminous efficiency may be achieved by concentrating the output light where the eye is most sensitive, but this is inevitably at the expense of colour accuracy, and usually on user comfort.

    The major advantage of ultra-efficient lighting is usually for new new builds, where savings may be made on air-conditioning equipment as well as on lighting. Unfortunately this is only really suitable where most occupied areas will not need good colour quality, as retrofitting is much more expensive than ab initio installaion.
    N.B. that there are (as yet not fully confirmed) indications that lighting quality affects mood, well-being, and absenteeism; if confirmed this could eventually make it very expensive to achieve efficiency at the expense of colour quality if the building is going to be mainly for human occupation.

    Is any data available on luminance of the series and glare control thereof.
    Have observed that the glare control needs an light obstructing device like diffuser,louvre etc. this negates the increase in luminous efficacy.Also resultant reduction in illuminance on object and may need higher wattage of lamp to correct for loss of lumens due to obstruction.
