When separate linear fixtures illuminate a long counter or a row of showcases, the design may call for a continuous line of light. Once installed, a dark gap may appear at a joint, or merchandise near the connection may look darker than items on either side. Reviewing these issues means looking at fixture ends, cabinet construction and the light reaching the products together.<\/p>\n\n\n\n

We recommend defining how continuity will be viewed, then marking cabinet divisions, fixture ends and emitting surface ends on the same drawing. A mockup containing the actual joint lets the team assess whether the lighting meets the intended result under normal display conditions.<\/p>\n\n\n\n

1. Identify where the dark gap appears<\/h2>\n\n\n\n

\u201cThere is a dark gap at the joint\u201d can describe several different observations. Record them separately before discussing adjustments.<\/p>\n\n\n\n

\n\n\n\n\n\n
What you see<\/th>\nWhere to look first<\/th>\nWhat to review<\/th>\n<\/tr>\n<\/thead>\n
A break in the emitting surface at the connection<\/td>\nThe fixture directly, or its image in a reflective surface<\/td>\nThe actual emitting surface ends, end construction and space between sections<\/td>\n<\/tr>\n
Darker merchandise or backing near the joint<\/td>\nThe illuminated surface, compared with either side<\/td>\nWhether light from the ends covers that area, and whether cabinet parts or props obstruct it<\/td>\n<\/tr>\n
Noticeable brightness or color differences between sections<\/td>\nAdjacent sections and the complete display<\/td>\nWhether configurations, control settings and installation conditions match<\/td>\n<\/tr>\n<\/tbody><\/table><\/figure>\n\n\n\n

An apparently continuous emitting surface still needs a check of the merchandise lighting. Some concealed arrangements principally require continuous illumination across the products, without customers seeing a complete luminous line directly.<\/p>\n\n\n\n

For example, shadows on a bag may also relate to its height, pockets and position. A dark area near a cabinet division does not by itself establish a joint problem. Use our bag display lighting guide<\/a> to identify the product details that need to remain visible.<\/p>\n\n\n\n

2. Mark cabinet divisions, fixture ends and emitting surface ends separately<\/h2>\n\n\n\n

On a plan or elevation, identify cabinet divisions, the physical ends of each fixture section, and where its emitting surface actually stops. Add a local detail showing end caps, connectors, cable exits and fixing positions.<\/p>\n\n\n\n

Confirm fixture body length and effective emitting length separately. If part of an end accommodates a cap or connection, bringing the bodies close together may still leave a break between their emitting surfaces. A connector that aligns the bodies also needs a review of the illuminated result.<\/p>\n\n\n\n

End construction should be confirmed for the specific model. A published linear fixture end design example<\/a> identifies translucent end caps and cable exit arrangements as design features for continuous rows. For your project, confirm the corresponding construction from the selected fixture's drawings and samples.<\/p>\n\n\n\n
