Detailed Description
Example 1:
Referring to fig. 1-2, the light guide block of the present invention includes a light guide block body 1, where the light guide block body 1 includes a light incident surface 2 and a first light emergent surface 3. The light incident surface 2 is provided with a light condensation groove 4, the light incident surface 2 is provided with an arc convex surface 5 corresponding to the light condensation groove 4, the first light emergent surface 3 is composed of a group of continuous steps 6, the whole steps are shaped like steps, and each step 6 is provided with a refraction surface 18 and a reflection surface 19.
Further, the included angle between the refractive surface 18 of the step 6 and the reflective surface 19 of the adjacent step 6 decreases toward the light incident surface 2 in sequence. Most desirably, the step 6 is composed of a first step 61, a second step 62, a third step 63, a fourth step 64, a fifth step 65, a sixth step 66, a seventh step 67, an eighth step 68, a ninth step 69, and a tenth step 70 in succession. And the included angle α1 of the first step 61 is 111.68 °, the included angle α2 of the second step 62 is 111.09 °, the included angle α3 of the third step 63 is 110.39 °, the included angle α4 of the fourth step 64 is 109.65 °, the included angle α5 of the fifth step 65 is 108.94 °, the included angle α6 of the sixth step 66 is 108.27 °, the included angle α7 of the seventh step 67 is 107.19 °, the included angle α8 of the eighth step 68 is 97.55 °, the included angle α9 of the ninth step 69 is 94.81 °, and the included angle α10 of the tenth step 70 is 78.25 °. By the design of the angles, the emitted light is in a fan shape as a whole and the light beam is uniform (as shown in fig. 4). The error of the included angle of the step 6 is within +/-5 degrees, and the approach effect can be achieved.
Furthermore, the light-condensing groove 4 and the arc-shaped convex surface 5 of the light-incident surface 2 are positioned below the horizontal plane 23 of the lower side surface 7 of the light-guiding block body 1, so that incident light can be uniformly reflected.
Further, mounting protruding blocks 8 are arranged on two sides of the light guide block body 1, so that the light guide block body 1 is positioned.
Further, the light guide block body 1 is provided with a second light emitting surface 9, and the second light emitting surface 9 is arc-shaped and is in smooth transition with the reflecting surface 19 of the first step 61, so that light is reflected from the second light emitting surface 9, and the overall light emitting area and brightness are improved.
Example 2:
referring to fig. 3, the light guide block according to embodiment 1 of the present invention includes a lamp base 10 and a lens 11 mounted on the lamp base 10, the light guide block body 1 is mounted between the lamp base 10 and the lens 11, and a light source assembly 12 is mounted on one side of the lamp base 10, and a light emitting portion of the light source assembly 12 is aligned with the light incident surface 2 of the light guide block body 1. The light source assembly 12 comprises an assembled bulb 13, a bulb holder 14 and a wire 15, wherein a positioning groove 16 is formed in the bulb holder 14, and a positioning block 17 matched with the positioning groove 16 in a positioning way is arranged on the lamp holder 10 so as to realize positioning and guiding of assembly.
Further, the bulb holder 14 is provided with a sealing ring 21 with three annular sealing ribs. The conventional bulb seat is directly and win-win matched with the lamp socket hole mainly by the outer surface of the part, so that the sealing and positioning effects are achieved, but the assembly process is pressed too tightly, the operation efficiency is low, and the risk of insufficient pressing exists. The structure design of the invention reduces the overall outer diameter of the bulb holder assembly positioning part, then the sealing ring structure is added, the sealing and positioning requirements are met through the sealing ring, and the assembly process is very easy to operate because the two sides of the sealing ring are provided with sufficient compression spaces, so that the bulb holder can be effectively sealed, and the risk that the assembly is not pressed in place is avoided.
Although the present invention has been described with respect to preferred embodiments, it will be understood by those skilled in the art that various changes and modifications can be made without departing from the scope of the invention, and the invention is not limited to the specific embodiments described above, but is intended to cover all modifications, equivalents and alternatives falling within the scope of the invention.
