- Basic lighting accessories
Radiator, reflector cup, circlip (red accessory), anti-glare cover, lamp body
a. Radiator: The die-casting aluminum material plays a role in cooling the lamps, and different processes have different cooling effects. The main light source brands on the market are: Preh, Cree, Osram, Citizen, Epistar, etc. At present, Cree single-color temperature chips are mostly used in lighting products on the market, but Cree does not produce dual-color temperature chips so far.
b. Reflective cup: The common brands on the market are: Grey, Cylande. The quality of the reflector will affect the spot and anti-glare effect. Some lamps use poor-quality reflectors, which may cause problems such as light spots and uneven concentration. Compared with good-quality brands, the price gap is large. Currently, the brands used by LifeSmart are Grey and Cylande.
c. Anti-glare cover, lamp body: According to the design style of the home, the anti-glare cover can be white, black, etc.; the lamp body has narrow sides, wide sides, square, round and other shapes. The composition of different lamp bodies is different, and different shapes can also be adopted according to different design styles.
- Lamp opening and height
The opening and height of the lamp affect the design of the lamp. Square and round are the more common opening shapes.
The ceiling is different, you need to choose surface installation or concealed installation, such as side hanging (no ceiling in the middle, with ceiling on the four sides), you need to use surface-mounted lamps; the entire ceiling has a ceiling but the depth is shallow, then you need to use lower height lamps.
The height is different, and the heat dissipation effect of the lamp is also different.
General opening size: 55cm/65cm/75cm/95cm/105cm, lamp height: 60-110cm
- Irradiation angle
10-15 degrees narrow beam foot: generally used for accent lighting, focusing on lighting a certain object, such as the display of ornaments/artworks/products.
25-36 degree spotlight: The light source at this angle is called local lighting source or wall washing light source, which is used to highlight the lighting level, contrast between light and dark, and highlight the texture and color of objects, suitable for wine cabinets and hanging paintings. The angle needs to be adjusted according to the distance of the lamp from the wall and the distance from other lamps.
60-120 degrees (over 40 degrees are collectively referred to as downlights): The light sources within this irradiation angle range can be called ambient light or basic lighting light. Compared with uniform lighting, the light in this angle range will be more diffuse, and the area will be larger and more scattered when hitting the ground. Suitable for bright areas such as bathrooms, kitchens, hallways, or for overall lighting, it can be understood as a small main light.
