(1) Light sources, lamps and accessories that meet the current national standards and regulations shall be selected for the building lighting project.

(2) Building lighting engineering construction should choose safe, efficient, long-term and energy-saving light sources, lamps and ballast accessories that meet the use environment conditions.

(3) The electrical protection category of night lighting equipment adopts Class I and Class II lamps; Three-level anti-electric shock products should be used in places that are particularly wet, have no unobstructed protection, the shell is easy to be touched by personnel, and lamps are not allowed to be grounded.

(4) The protection level of the selected lighting fixtures must reach IP65 or above; The protection grade of the selected 24V switching power supply, junction box, controller and sub-controller is IP65, and the protection grade of the distribution box is IP65.

2, the selection principle of light source

Floodlighting uses a light source similar to the color tone of the building surface. Advertisements, signboards and other lighting use light sources with good color rendering as lighting sources.

3, lamps and lanterns selection principle

The light distribution selection of lighting lamps in architectural lighting engineering is based on lighting objects; The selected lamps and lanterns meet the safety requirements and the surrounding environment requirements;

Building lighting engineering chooses lamps with good luminous flux maintenance performance; This building lighting project uses integrated lamps as far as possible, which is convenient for installation, maintenance, cleanliness, beauty and durability.
