To be more specific, in this embodiment, when the total power of the LED light source 32 (i.e. the total power of the lamp beads) in the light emitting assembly 30 is not greater than 60W, the first reflecting portion 511 and the plurality of light splitting portions 513 connected in sequence are only needed to achieve the light dispersing effect, so as to reduce the glare value of the emitted light.
In this embodiment, when the total power of the LED light source 32 in the light emitting assembly 30 is larger (>60W), a plurality of light splitting units need to be disposed below the first reflection portion 511, the specific number is determined by the light intensity, an individual light splitting portion 513 is connected to the bottom of the light splitting unit at the bottom, and the light splitting unit is composed of a second reflection portion 512 and a light splitting portion 513, so as to perform gradual dispersion after the light is reflected for multiple times, and disperse a part of the light each time, thereby finally reducing the glare value of the emitted light and not hurting eyes.
