Description

TECHNICAL FIELD

[0001] The utility model relates to solar warning light technical field, especially in a kind of solar warning light shell structure. BACKGROUND

[0002] As a kind of active light-emitting warning device relying on solar power, solar warning light has been widely used in road construction area, temporary control section, parking lot entrance, channel boundary and various dangerous warning scenes with its outstanding advantages such as no external power supply, convenient installation, energy saving and environmental protection.The core function is to remind passing pedestrians and vehicles to pay attention to environmental risks through continuous and stable light warning signals, so as to effectively reduce the incidence of safety accidents, therefore the luminous intensity and visual range of warning light directly determine the advantages and disadvantages of its warning effect.

[0003] In the structure of solar warning light, the shell component not only bears the protection function of protecting the internal solar panel, battery, lamp bead, control module and other core components from wind, rain, sand, collision and other external environmental damage, but also directly affects the absorption efficiency of solar energy and the transmission and diffusion effect of light, which is the key structure to ensure the comprehensive performance of warning light. In order to consider the two core needs of solar energy utilization and light warning, a relatively mature solar warning light shell structure design scheme has been formed in the prior art.

[0004] The existing shell of this type usually takes functional division as the design core, and a solar panel light-transmitting area is specially arranged in the central area of the shell. The area is generally made of high-transmittance acrylic or polycarbonate material, which is used to assemble the solar panel and ensure that sunlight can efficiently penetrate the surface of the solar panel, so as to ensure the full absorption and conversion of solar energy and provide stable electric energy for the operation of the warning light. At the same time, in order to realize the light warning function, a first light guide part is arranged around the above-mentioned solar panel light-transmitting area, which is used to refract and scatter the light emitted by the lamp beads, so that the light can be evenly diffused outside the shell, thereby forming a warning lighting effect that can be observed.

[0005] However, in the actual application process, the limitations of the above-mentioned traditional shell structure gradually emerge. The core problem is that the functional area division of the shell leads to a serious limitation of the light-emitting area. Since the first light guide part can only be arranged in a ring structure around the periphery of the solar panel light-transmitting area, the light-emitting area completely depends on the size of the solar panel and the overall specification of the shell. In the limited shell volume, the area ratio of the ring-shaped light guide area is extremely low. This limited light-emitting area directly leads to a narrow light coverage range and a fast brightness decay of the warning light, especially in complex environments with low visibility such as rain, fog and night, the recognition distance of the warning signal is greatly shortened, and safety hazards caused by delayed warning are easily caused.

[0006] With the increasing performance requirements of warning devices in the fields of road traffic safety, engineering construction protection and the like, how to optimize and improve the structure of the solar warning lamp shell without reducing the solar energy absorption efficiency and damaging the original protective performance of the shell, so as to further increase the effective light emitting area, improve the eye-catching degree and identification distance of light warning, has become an important technical problem to be solved by the technical personnel in the field, and is also a key development direction to promote the upgrading of solar warning lamp products. Practical new type content

[0007] The present utility model aims at solving at least one of the technical problems existing in the prior art. To this end, the present utility model provides a solar warning lamp shell structure with increased effective light emitting area.

[0008] A solar warning lamp shell structure designed for this purpose comprises a shell, a solar panel light transmission area is arranged at the center of the shell, a plurality of first light guide parts are arranged in a circumferential array on the outer side of the solar panel light transmission area, the first light guide parts are provided with second light guide parts extending towards the solar panel light transmission area or extending towards the inner wall of the shell, and the wall surface of the first light guide parts and the second light guide parts adhered to the shell is a light emitting surface.

[0009] As a preferred option, two adjacent first light guide parts are connected to each other.

[0010] As a preferred option, the shell is provided with an annular rib, the solar panel light transmission area is arranged in the annular rib, the second light guide part extends towards the solar panel light transmission area, and the second light guide part is at least partially adhered to the annular rib.

[0011] As a preferred option, the wall surface of the first light guide part towards the lamp panel side is provided with a light inlet cavity, and the light inlet cavity and the lamp beads of the lamp panel correspond to each other.

[0012] As a preferred option, the second light guide part is in a sheet structure. Compared with the prior art, the solar warning lamp shell structure of the utility model realizes double promotion of light emitting performance and structural stability through optimization of light guide area design and structural connection mode, and has remarkable beneficial effects. In the aspect of light emitting area expansion, the structure discards the limitation of the traditional shell that only sets a single annular light guide part in the periphery of the solar panel light transmission area, and instead arranges multiple first light guide parts in a circumferential array outside the solar panel light transmission area, so that the light guide area is converted from a continuous annular shape to a multiple unit distributed layout, effectively breaking the constraint of the original structure on the light emitting range. At the same time, each first light guide part is extended with a second light guide part, and no matter whether the second light guide part extends towards the solar panel light transmission area or extends towards the inner wall of the shell, the structure connected with the first light guide part forms an additional light emitting carrier, and the wall surface of the first light guide part and the second light guide part attached to the shell is used as a light emitting surface, so that the light can be diffused outward through the synergistic effect of the main and auxiliary light guide structures. Compared with the traditional structure, the overall light emitting area is greatly increased, thereby significantly widening the coverage range of the warning light, improving the recognition distance and eye-catching degree of the warning signal in complex environments, and effectively enhancing the warning effect.

[0013] In terms of structural strength reinforcement, the second light guide part forms a "reinforcing rib" structure connecting the first light guide part and the shell main body or the peripheral structure of the solar panel light transmission area. When the second light guide part extends towards the solar panel light transmission area, it can form indirect or direct support cooperation with the peripheral structure of the solar panel light transmission area, so that each first light guide part is fixed to the central area through the second light guide part. When the second light guide part extends towards the inner wall of the shell, it can form a stable connection with the inner wall of the shell. Both extension modes can transmit external force received by the first light guide part to the shell main body or the central support structure, avoiding the problem of local stress concentration caused by the single annular structure of the traditional annular light guide part. This design makes the first light guide part not an isolated peripheral structure, but an integrated structure with stronger rigidity through the second light guide part and the shell, effectively improving the overall structural strength and impact resistance of the first light guide part, reducing the risk of damage caused by collision and vibration during transportation, installation and use, and prolonging the service life and reliability of the shell.

[0016] Referring to Figs. 1 to 3 A solar warning light shell structure, comprising a shell 10, a solar panel light transmission area 110 is arranged at the center of the shell 10, a plurality of first light guide parts 20 are arranged in a circumferential array on the outer side of the solar panel light transmission area 110 of the shell 10, the first light guide part 20 is provided with a second light guide part 30 extending towards the solar panel light transmission area 110 or extending towards the inner wall of the shell 10, and the wall surface of the first light guide part 20 and the second light guide part 30 adhered to the shell 10 is a light emitting surface.

[0017] The use principle of the solar warning light shell structure is to take "energy conversion-light transmission-warning output" as the core logic, and each structure cooperates to complete the high-efficiency warning function. The specific process is as follows: First, the energy supply link, the solar panel light transmission area 110 at the center of the shell 10 adopts high-transmittance optical material, which can pass natural sunlight to the surface of the solar panel assembled inside without hindrance. The solar panel converts light energy into electrical energy and stores it in the energy storage battery to provide continuous power for the lamp beads and control module of the warning light. The structure design of the solar panel light transmission area 110 in this link directly guarantees the efficiency of energy acquisition and is the basis for the realization of subsequent functions.

[0018] In the warning function execution stage, the lamp beads 50 (arranged corresponding to the position of the first light guide part 20) are electrified and emit light, and the light preferentially enters the plurality of first light guide parts 20 distributed in a circumferential array. The optical structure (such as prism lines, frosted layer) inside the first light guide part 20 preliminarily converges and guides the light, and part of the light directly diffuses outward through the light emitting surface of the first light guide part 20 and the shell 10, forming a basic warning light effect.

[0019] At the same time, the second light guide part 30 extended by the first light guide part 20 constructs a secondary light guide path, further expanding the warning range. After the light enters the first light guide part 20, it is divided into two parts, one part of the light directly outputs outward through the light emitting surface of the first light guide part 20, and the other part of the light is conducted into the second light guide part 30 connected thereto, and then outputs outward through the light emitting surface of the second light guide part 30 after transmission in the second light guide part 30. This design of split light guide makes the light originally concentrated in a single light guide area realize multi-path output through the main and auxiliary light guide structures, which not only fills the light-emitting blank area on the shell, but also expands the overall coverage range of the warning light, making the warning effect more comprehensive.

[0021] In the utility model, the adjacent two first light guide parts 20 are connected with each other. In the embodiment, the connected first light guide parts 20 form a continuous annular light guide frame, and the dispersed light guide units are integrated into a whole, so that the rigidity and the breaking resistance of the light guide structure are greatly improved; in the light guide effect, the connection design eliminates the light-emitting gap between the adjacent light guide parts, so that the warning light forms a coherent and uniform light band, the light layer is avoided, and the visual coherence and the prominence of the warning signal are enhanced.

[0022] In the utility model, the second light guide part 30 is in a sheet structure. The sheet design makes the second light guide part 30 more easily pasted with the annular bead 100, the connection stability is enhanced, the overall weight of the light guide structure is reduced, and the strength and the lightweight demand are considered.
