The housing of the guide arrows is the base 400 and a complete guide arrow has multiple bases 400, since a complete guide arrow can be made by splicing together several section modules of the guide arrow, each section module having a base 400. The interior of the base 400 is filled with a filling material mainly comprising epoxy resin and light-transmitting mineral crystal particles. Inside the base 400, it is usually employed to place the LED light source first, and then pour the mixture 600 of epoxy resin and light-transmitting mineral crystal particles inside the base 400 to fill the whole gap inside the base 400. After the epoxy resin is cured, namely the filling material in the epoxy resin is solid and is hardened, the PCB and the LED are fixed in the base through the filling material, and a subsection module is manufactured. Wherein a curing agent may be added to the mixture 600 of epoxy resin and light-transmitting mineral crystal particles as needed to shorten the curing time. The cured epoxy resin can play a role in protecting the subsection module, the light-transmitting mineral crystal particles can improve the light-emitting effect, and when the LED light source emits light, the light-transmitting mineral crystal particles can refract the light to enable the whole subsection module to emit light, so that the observation angle can be enlarged. The utility model discloses a surround the uncovered container that constitutes by bottom support board and side direction backup pad and come as the base of direction arrow point, can effectively strengthen the side direction and support, reduce warpage.

The LED light source of this embodiment is made by the LED lamp, the LED lamp herein adopts the common LED lamp with super bright white, large angle and small power on the existing market, specifically, the LED light source includes the LED light emitting diode 300, the LED light emitting diode 300 is installed on the PCB circuit board 200 in the mode of equidistant uniform arrangement, as shown in fig. 1, the LED light emitting diode 300 is uniformly arranged at one side of the PCB circuit board 200, and there is a blank between two adjacent LED light emitting diodes 300, a reserved round hole with a diameter of 6mm to 8mm is arranged at the blank of the PCB circuit board 200, that is, the PCB reserved hole 100, for when preparing a subsection module, in the process of adding the mixture 600 of epoxy resin and light-transmitting mineral crystal particles, both the epoxy resin and the light-transmitting mineral crystal particles can be transmitted, thereby making the epoxy resin firmer after curing. When the guiding arrow disclosed in this embodiment is manufactured, in order to pour the mixture of the epoxy resin, the curing agent and the transparent mineral crystal particles into the base 400, in this embodiment, the transparent mineral crystal particles with a diameter of 5mm to 8mm are selected, and in order to optimize the light emitting effect of the LED light source, the mixture 600 of the epoxy resin and the transparent mineral crystal particles and the curing agent are first poured into one half of the volume of the base 400, then the LED light source (including the PCB 200 and the LED 300) is placed into the middle position of the base 400, the power line 500 is LED out from one side of the PCB 200, and then the filling material is used to fill the remaining one half of the volume of the base 400. According to the design, the LED light source is arranged in the middle of the inner part of the base 400, and the mixture 600 of the epoxy resin and the light-transmitting mineral crystal particles is filled around the LED light source, so that after the epoxy resin is cured, the LED light source is not easily interfered by external pressure due to the fact that the LED light source is arranged in the middle, the integrity of a circuit where the LED light source is arranged can be effectively guaranteed, and the service life of a guide arrow is prolonged.

The shape of the PCB 200 is the same as the shape of the guide arrow, i.e. the shape of the PCB 200 inside each section module is the same as the shape and size of the base 400 where it is located, so that the shape and size of the PCB 200 can be placed inside the base 400 of the section module, and the area of all the section modules can be distributed according to the shape and size of the section module itself.
