What is a tree light?

The tree light is the kind of LED flood light that we usually project under the tree at night to green the landscape lighting and make the tree look beautiful, which is similar to the wall washer.

Flood light, a luminaire that makes the illumination on the specified illuminated surface higher than that of the surrounding environment. Also called floodlights. In general, it is capable of aiming in any direction and has a structure that is not affected by climatic conditions. Mainly used for large-area mines, building outlines, stadiums, overpasses, monuments, parks and flower beds, etc. Therefore, almost all large-area lighting fixtures used outdoors can be regarded as floodlights. The angle of the outgoing beam of the floodlight is wide or narrow, and the variation range is between 0° and 180°. The beam with a particularly narrow beam is called a searchlight.

The luminaire adopts a rotationally symmetric reflector, and the axis of symmetry of the light source with rotationally symmetric light distribution is installed along the axis of the reflector. The iso-intensity curves of such lamps are concentric circles. When this form of flood light is illuminated by a single lamp, an oval light spot is obtained on the illuminated surface, and the illumination is uneven; but when illuminated by multiple lamps, the light spots are superimposed on each other, which can produce a satisfactory lighting effect. For example, hundreds of rotationally symmetrical floodlights are commonly used in stadiums, which are installed on high towers around the stadium to obtain high illumination and high uniformity lighting effects.
