As an alternative embodiment, the first beads 52 located at the two ends of the first substrate 51 are the same as the adjacent ends of the first substrate 51, and the first beads 52 are distributed in the middle of the first substrate 51 due to the same distance between the two adjacent first beads 52, so that the symmetry is good; the overall dimension and the bead distribution of the first light source assembly 5 and the second light source assembly 6 are the same, and during installation, enough gaps are left between the first substrate 51 or the second substrate 61 and the housing assembly 1, and the first substrate 51 and the second substrate 61 are arranged in a staggered manner along the length direction, so that the second beads 62 on the opposite side are staggered with the first beads 52, in this embodiment, except the second beads 62 on one end of the second substrate 61, the remaining second beads 62 are located between the two adjacent first beads 52, so that only one type of light source assembly is required to be designed, and the uniformity of the light emission of the side-emitting flat panel lamp can be improved, and dark spots are avoided.
Further, as shown in fig. 4, the first substrate 51 has the same shape as the second substrate 61 and is strip-shaped, the first substrate 51 and the second substrate 61 are arranged along a first direction in the length direction, the first beads 52 are arranged along a middle line of the first substrate 51 in the length direction, the second beads 62 are arranged along a middle line of the second substrate 61 in the length direction in a spaced manner, the spacing between adjacent first beads 52 is the same as the spacing between adjacent second beads 62, the distance between the first beads 52 near the ends of the first substrate 51 and the ends of the first substrate 51 is a first distance, the distance between the second beads 62 near the ends of the second substrate 61 and the ends of the second substrate 61 is a second distance, the first distance and the second distance are different, the first substrate 51 and the second substrate 61 are aligned along the length direction, specifically, the distance between the first beads 52 near the two ends of the first substrate 51 and the second substrate 61 and the second ends of the second substrate 61 are different from each other, the distance between the adjacent first beads 52 near the two ends of the first substrate 51 and the second substrate 61 is different from the second ends of the first bead near the first ends of the second substrate 61; the first substrate 51 and the second substrate 61 are symmetrically disposed in the longitudinal direction. As an alternative embodiment, the first light source component 5 and the second light source component 6 are different, the two light source components are symmetrically installed on two opposite sides of the housing component 1, the installation is convenient, except for the second lamp beads 62 located at one end of the second substrate 61, each remaining second lamp bead 62 is located in the middle of two adjacent first lamp beads 52, so that the light emitting range of the dislocated second lamp beads 62 covers the gap between the adjacent first lamp beads 52, the light emission is more uniform, the uniformity is far better than that of a lamp with symmetrical lamp beads, dark spots can be effectively avoided, the light efficiency is improved, and the energy conservation and environmental protection are realized.
Further, the distance between the adjacent first beads 52 is 3.5mm-6mm; and/or, the spacing between adjacent second beads 62 is in the range of 3.5mm-6mm. Specifically, if the gap is smaller than 3.5mm, the arrangement quantity of the lamp beads is excessive, the internal temperature is increased, and potential safety hazards exist; if the gap is larger than 6mm, the lamp beads are loosely arranged, dark spots can appear among the lamp beads due to uneven light emission, the uniformity is insufficient, and the attractiveness is affected.
Further, the housing assembly 1 includes a frame 12 and a cover plate 11 connected to the frame 12, the light guide assembly 2 is connected to the frame 12, the cover plate 11 and the light guide assembly 2 are disposed opposite to each other, and the first light source assembly 5 and the second light source assembly 6 are disposed between one side of the cover plate 11 and the light guide assembly 2; the side-emitting flat panel lamp further comprises a driving assembly 3 connected with the first lamp bead 52 and the second lamp bead 62 respectively; the driving assembly 3 is disposed at the other side of the cover plate 11. Specifically, the typical side-lit flat panel light is very low, typically only 40% -60%; the highest luminous flux of the 4014 light source is only 160lm/W, and the light efficiency of a flat plate lamp using the 4014 light source is only about 80%; in this embodiment, the light flux of the 2835 light sources may reach 210lm/W, and the 2835 light sources are selected for the first lamp beads 52 and the second lamp beads 62, so that the light efficiency is further improved to reach more than 90%.
Further, the light guide assembly 2 further includes a diffusion plate 23, a light guide plate 22, and a reflective paper 21, where the diffusion plate 23, the light guide plate 22, and the reflective paper 21 are sequentially stacked; the light guide plate 22 has a protruding side 221 protruding from the light guide plate 22 and the reflective paper 21, the inner side of the frame 12 has a limiting edge 121, one surface of the protruding side 221 is opposite to the limiting edge 121, and a limiting block 7 abutting against the other surface of the protruding side 221 is arranged on the inner side of the frame 12 to prevent the light guide plate 22 from moving, so that the light guide plate 22 is reliably installed; the first lamp beads 52 are arranged opposite to the protruding side 221, and the gap is more than or equal to 0.8mm.
Further, the second lamp bead 62 is disposed opposite to the protruding side 221, and the gap is greater than or equal to 0.8mm.

As an alternative embodiment, a sufficient safety distance is left between the first and second beads 52 and 62 and the light guide plate 22; the distance between the light source and the light guide plate 22 directly influences the light efficiency of the side-emitting flat panel lamp, and the larger the distance is, the lower the efficiency is; moreover, the light guide plate 22 is generally made of acrylic material, is easy to be heated, damp and expand, and is easy to generate blue light if extruded to the light source, so that a sufficient safety distance is reserved between the first lamp bead 52 and the second lamp bead 62 and the light guide plate 22, in this embodiment, the first lamp bead 52 and the convex side 221 are oppositely arranged, the gap is more than or equal to 0.8mm, the second lamp bead 62 and the convex side 221 are oppositely arranged, the gap is more than or equal to 0.8mm, the light efficiency can be guaranteed to reach the maximum value, and the influence of blue light on illumination can be avoided.
Further, the first light source assembly 5 and the second light source assembly 6 are both provided with a protection block 8 for abutting against the convex side 221, and the height of the protection block 8 is higher than the height of the lamp beads. The limiting block 7 is made of rubber. In the embodiment provided by the invention, as shown in fig. 8 to 10, the inner side of the frame 12 has a limiting edge 121, and the protecting block 8 is abutted against one surface of the protruding side 221, so that the protecting block 8 is positioned between the limiting edge 121 and the protruding side 221, and the installation is more reliable.
In particular, the protection block 8 is made of hard material. In this embodiment, the stopper 7 made of rubber material is adopted to provide a certain buffer when the light guide plate 22 collides with the stopper 7 or during the installation process, so that the light guide plate 22 can be prevented from cracking or scratching due to accidental sliding or collision while the stopper 7 is ensured to be limited and reliable, and the influence on the scattering direction of the light emitted by the light guide plate 22 for guiding the light beads is avoided.
Specifically, an adjusting structure for adjusting the position of the first light source assembly 5 or/and the second light source assembly 6 may be optionally disposed in the housing assembly 1, the adjusting structure may include a bolt and a spring, the bolt may be screwed and pass through the housing assembly 1, the bolt abuts against one end of the first light source assembly 5 or/and the second light source assembly 6, and the spring abuts against the other end of the first light source assembly 5 or/and the second light source assembly 6. When the light source is produced, assembled and used, the positions of the first light source assembly 5 and/or the second light source assembly 6 can be adjusted by rotating the bolts so as to meet different requirements. For example, when different lamp beads are adopted, the lamp beads of the first light source assembly 5 and the second light source assembly 6 can be adjusted to a set dislocation distance through the adjusting structure, so that the production cost is reduced.
