. New light source: LED lamp (light-emitting diode); EDL lamps (electrodeless lamps); EL lamps (electroluminescent lamps).

2. LED lights have four colors: red, orange, green and blue. Combining blue with a phosphor results in a white light source.

3. Main indoor light sources: tungsten halogen lamps, fluorescent lamps, etc.; Main light sources for outdoor use: high-pressure sodium lamps, metal halide lamps, high-pressure mercury lamps, hernia lamps (searchlights), etc.

4. Lighting fixtures

1. The key points of choosing lamps and lanterns: (1) price (2) delivery time (3) lamp size (4) material (5) workmanship (6) light source (7) use notes.

2. The size of the lamp has a significant impact on the visual effect of the overall space.

3. Understand the light distribution curve diagram and figure out how the light is emitted from the lamp. The light distribution curve diagram can illustrate: (1) what angle and how much light intensity is the light emitted from the lighting fixture.

4. Example: If the luminous flux of the lamp is 5000lm, then the light intensity value (cd) of the longitudinal axis should be multiplied by 5 times. The value of the luminaire vertically downward is about 420cd. Then, 420cdx5 = 2100cd here, illuminance = light intensity I (cd) / distance d2 (m2). (Average illuminance = luminous flux F/area m2).

5. Downlight can be used for the effect of light wall, and the wall is not required to be smooth.

6. Chandelier, (1) A chandelier is generally installed above the dining table, and the recommended chandelier size is 1/3 to 1/2 of the longitudinal length of the dining table. (2) It is more appropriate to install the lamp at a height of about 60cm above the dining table.

7. Ceiling lamp.

8. Spotlights, (1) The installation methods of spotlights include direct type, slide rail type, soft rail type, clamp type, etc.

9. a wall lamp.

10. Placing lamps.

11. Slide rail lighting fixtures, suitable for boutiques, clothing stores, hotels, shopping malls, jewelry stores, entertainment venues, restaurants, exhibition venues, etc.

12. a grille fluorescent lamp plate.

13. Outdoor lighting fixtures, (1) halogen tungsten lamp for small-scale illuminated objects, HID lamps are used when the illuminated objects are too large. (2) The lamps and lanterns used in coastal areas must be corrosion-resistant.

5. Lighting design process

1. Most of the work of the lighting designer is done together with the architect and the interior designer.

2. Lighting design process: (1) entrust [design budget, design scope, design period, customer requirements] (2) basic plan [master the building space, the influence of daylight, the type and configuration of furniture and interior decoration materials] (3) the basic design [light image diagram, with computer drawing, model and other simulations; calculate illuminance; Selected luminaires; configure lamps and lanterns; (4) Implementation of the design [with the change of architecture, interior design, budget, etc., review and study; Decide on lighting procedures, lights out, and dimming] (5) Supervision and management [focus the light and check the quality of the lamps] (6) Record [measure the illuminance and take photos].

3. Lighting utilization rate refers to how many percent of the beam radiated from the lamp reaches the floor or work surface: average illuminance = (luminous flux of 1 lamp x number of lamps x lighting utilization rate x maintenance factor) / floor area.

6. Physical lighting of the main space

1. Landscape lighting (1) Types of light sources and lighting fixtures (2) Establish the concept (use the smallest possible illumination to obtain a higher lighting effect)

2. In any case, the light of the lighting fixture cannot directly enter the human eye.
