A light guide apparatus includes a light guide layer and an injection layer further including light injection elements and respective light bypass elements disposed optically upstream of the light injection elements. The light injection elements and / or the bypass elements may take the form of air prisms. There is an axial index of refraction variation between the light guide layer and the injection layer. The axial index of refraction variation may be discrete or may be an axial gradient index variation.

The invention relates to a fixing frame for an illuminating lamp, in particular to a fixing frame for an illuminating lamp in a construction site. According to the fixing frame for the illuminating lamp in the construction site, the illuminating lamp can be prevented from shaking leftwards and rightwards, and light of the illuminating lamp can be gathered. According to the technical scheme, the fixing frame for the illuminating lamp in the construction site comprises fixing rods, inserting rods, a mounting column, sliding rails, sliding blocks, protruding blocks, springs, clamping plates and the like. The lower portions of the left side and the right side of the mounting column are connected with the fixing rods correspondingly, the front sides and the rear sides of the fixing rods are connected with the inserting rods correspondingly, the left side and the right side of the top of the mounting column are connected with the sliding rails correspondingly, and the sliding blocks are slidably connected to the sliding rails. According to the fixing frame for the illuminating lamp in the construction site, by pulling a pull rod downwards, pull ropes drive the sliding blocks on the leftside and the right side and parts on the sliding blocks to move away from one another, then a user places the illuminating lamp between the clamping plates on the left side and the right side, the clamping plates on the left side and the right side are reset under the effect of the springs to fix illuminating lamp, and in this way, the illuminating lamp can be prevented from shaking leftwards andrightwards.
