1. Look at the "shading angle"

The shading angle of conventional lamps is determined according to the elevation angle of human normal vision, and the normal attention range of human eye is from 30 ° above to 60 ° below. Therefore, when the shading angle of the lamp is greater than 30 degrees, the light can be prevented from directly entering the human eye. In the environment with high lighting quality requirements, lamps should have 30 ° to 45 ° shading angle.

2. Optional lamp mode

Spotlights can be divided into concealed spotlights, surface mounted spotlights and track mounted spotlights, which correspond to concealed, surface mounted and combined with track respectively.

(1) Concealed spotlight

The concealed spotlight is to embed the spotlight evenly in the ceiling, which can keep the ceiling fresh and delicate. At the same time, there is no lack of lighting function, so that there is no light source dead angle in the space. If you want to install concealed spotlights, you'd better buy them at or before the ceiling stage, because they are embedded in the ceiling. Buy as early as possible, in the ceiling stage, let the master leave holes according to the lamps you bought. In addition, the ceiling of concealed spotlight only needs 5-7cm thick, which is much thinner than the traditional 13cm thick ceiling, so the height of luminaire should be less than 7cm.

(2) Surface mounted spotlight

Surface mounted spotlight is a kind of ceiling to ceiling, light down lighting. There are certain requirements for appearance presentation. We should not only choose the light well, but also consider the color value of the lamp itself, so as to "turn on the light well, turn off the light well".

(3) Track spotlight

The track spotlight should be installed on the special guide rail, and the position and light casting direction of the luminaire on the track can be adjusted according to the actual needs. Installation of rail spotlight can be directly installed on the ceiling, without ceiling, but also to achieve suspension line installation, more decorative.

3. Selective power

According to the room area, height, lighting demands and other factors, we can choose the power of the spotlight. For the conventional family, the power of the spotlight is 3-10W. If it is a larger space, we can choose a higher power luminaire.

4. Brand selection

There are too many brands of lamps and lanterns, so you must buy samples first, and then make a decision after personal experience. Although the spotlight does not require high quality, but still try to choose the brand to buy.
