In a specific application, since two pairs of adjacent protruding portions 112 are disposed on the first reflecting surface 111 in an inclined manner, when the adjacent protruding portions 112 are disposed symmetrically along the middle branching line, one pair of protruding portions 112 is provided with the first light bead 151 and the second light bead 152, and the other pair of protruding portions 112 is provided with the third light bead 153 and the fourth light bead 154, so that the first band light or the second band light is reflected between the second reflecting surfaces 1121, the first light bead 151 and the second light bead 152 respectively emit the first band light and the second band light and are reflected and alternately mixed on the second reflecting surfaces 1121, that is, the first band light or the second band light irradiates from one protruding portion 112 to the other protruding portion 112 and is reflected back to the protruding portion 112 where the second light bead is located again, wherein the third gain band light and/or the fourth gain band light emitted by the third light bead 153 and the fourth light bead 154 respectively is mixed with the first band light and the second band light, so that the color temperature of the light can be adjusted, and the spectrum of the light can be changed.
In one possible embodiment, the angle between the protruding portion 112 and the first reflecting surface 111 is denoted as a, the distance between two adjacent protruding portions 112 is denoted as l, and the height of the protruding portion 112 is denoted as h, which satisfies the relationship: a is more than or equal to 45 degrees and less than 90 degrees; l is more than or equal to 10mm and less than or equal to 25mm; h is more than or equal to 5mm and less than or equal to 8mm.

In this embodiment, the included angle a is inversely related to the spacing l between the protruding portions 112, that is, when the value of a is 45 °, the value of l may be 25mm, and the value of h may be 8mm, so that the space where the first lamp bead 151, the second lamp bead 152, the third lamp bead 153 and the fourth lamp bead 154 are mounted is kept, and the first band light, the second band light, the third gain band light and/or the fourth gain band light can be satisfied, and the basic requirement that the second light is reflected back to the protruding portion 112 after the first band light and the second band light are irradiated from one protruding portion 112 to another protruding portion 112 is satisfied, but when the value of the spacing l between the protruding portions 112 is too large, the fine adjustment of the mixed light effect is not facilitated, and therefore, preferably, when the value of a is 60 °, the value of l is 15mm, and the value of h is 6mm, the first band light or the second band light can be satisfied, and the basic requirement that the second band light is reflected back to the protruding portion 112 is also reflected back to the second light is satisfied, and the fine adjustment of the light effect can be realized at the same time, and the fine adjustment of the second lamp bead is realized.

In this embodiment, the smaller the value of L2 is, the thinner the overall thickness of the lamp is, but since the distance from the prism sheet 130 to the lamp panel 110 is shortened, the number of times of refraction of light is reduced, resulting in weaker mixed light effect, and the larger the value of L2 is, the better the mixed light effect is, but the overall thickness of the lamp is thick, therefore, preferably, the value of L1 is 55mm and the value of L2 is 25mm.
