Professional Lighting Designers' Association

The Professional Lighting Designers' Association (PLDA), formerly the European Lighting Designers' Association (ELDA+), is an international association of architectural lighting designers headquartered in Gütersloh,Germany. Initially established in 1994 as a European organization, PLDA has since expanded its reach beyond Europe, with a growing membership in Asia and North America. Despite experiencing a liquidation in 2014 due to insolvency, PLDA continues to serve as a voluntary federation of lighting designers and consultants on an international scale, aiming to enhance the profession's standing and promote its recognition.

Membership
Voting members are Fellow members, Professional members and Associate members. Fellow members are deemed to have excelled in contributing to the Architectural Lighting Design profession and PLDA. Professional members are those who own an independent practice or work in an independent practice, and have a certain number of years of experience in lighting design. The same applies to Associate members, except their years of experience are less.

Non-voting members are Design members (independent, but with little or no experience as an independent designer), Student members and Affiliate members. Affiliate members are those who are not full-time lighting designers, but are very interested in lighting design or need it for their profession.

Collaboration
PLDA collaborates with other lighting associations, including CIE, IES and other groupings of lighting designers around the world. With the Institution of Lighting Engineers, PLDA has a partnership agreement, in order to foster deeper understanding between the lighting profession and engineering practitioners.

The organization's official magazine is the Professional Lighting Design, published by the VIA-Verlag. Every member receives the magazine automatically. The VIA-Verlag maintains very close ties with PLDA by, for example, organizing many events for the association.

Education
The Professional Lighting Designers' Association believes that education is the key to establishing Lighting Design as a serious profession. The association thus dedicates a large portion of its time to the organisation and support of education programmes at university level. PLDA has an Educators' network. International educators meet on a regular basis. PLDA works closely with many universities around the world, for example at KTH in Stockholm/S, the Hochschule Wismar/D, Fachhochschule Hildesheim/D, Parson's New School of Design in NYC/USA and Bachelor and Masters programmes in many European countries.

The Workshop Programme with up to four major workshops a year gives students and young designers the opportunity to work in teams under the guidance of a professional lighting designer to develop and implement a lighting design concept on a real project. Some universities have these workshops in their curriculum.

The Professional Lighting Designers' Association stages the Light Focus conference once a year, usually in conjunction with a major lighting fair event, e.g. Light+Building in Frankfurt/D or Euroluce in Milan/I. The sessions cover topics of interest and relevance to all those involved in architectural lighting design and bring to light a variety of professional themes.

The Professional Lighting Designers' Association stages the Vox Juventa conference for young designers once a year. The winning speaker receives a money prize.
