Description

Technical Field

[0001] This invention belongs to the field of lighting equipment technology, specifically relating to a lighting system that enables light sources to be maintained without the need for climbing, and is particularly suitable for scenarios such as homes, roads, and squares where lighting devices need to be installed at height. Background Technology

[0002] Traditional lighting fixtures (such as indoor chandeliers and outdoor streetlights) typically integrate the light source with the lighting structure. To ensure illumination range and brightness, the entire fixture must be installed at a high location (such as on a roof or at the top of a light pole). However, the light source is a consumable component, and its replacement or maintenance requires the use of climbing tools (such as ladders or aerial work platforms), which presents the following problems: Maintenance is difficult: working at height requires professional tools and operating skills, especially for home users (such as the elderly), the operation threshold is high when replacing the light source themselves; High safety risks: Falls are likely to occur during the ascent process; High cost: Maintenance of outdoor public lighting (such as streetlights) requires the use of climbing equipment, which increases labor and equipment costs; Significant limitations: It is almost impossible for people with limited mobility (such as the elderly and disabled) to maintain the light source independently.

[0003] Therefore, there is an urgent need for a lighting system that can achieve maintenance of light sources without requiring climbing to reach them, in order to solve the above problems. Summary of the Invention

[0004] In view of the shortcomings of existing technologies that require climbing for light source maintenance, the purpose of this invention is to provide a lighting system that eliminates the need for climbing to maintain light sources, thereby simplifying the light source maintenance process and reducing safety risks and maintenance costs.

[0005] The technical solution adopted in this invention is as follows: A lighting system that requires no climbing for maintenance includes a light source and a lighting unit, with the following specific structure: light source Employ light-emitting devices with directional light emission characteristics, including but not limited to flashlights and follow spots; As a consumable part, it should be installed at a low location (such as the lower part of a wall or light pole), preferably 1.3-1.7 meters above the ground, to ensure that adults can easily reach it and children cannot access it (to avoid accidental operation). It connects to a power supply module (such as AC power or a battery) and has a detachable and replaceable structure (such as a snap-on or threaded interface).

[0006] Lighting unit Used to reflect the received light distribution onto the target illumination area.

[0007] A convex mirror or a concave mirror can be used. Considering that the light emitted by the directional light source is not absolutely parallel light rays and generally spreads outwards from the center, if the same lighting effect is to be achieved, the absolute value of the radius of curvature of the convex mirror used should be less than the absolute value of the radius of curvature of the concave mirror. The actual radius of curvature and the mirror diameter need to be adapted according to the size of the lighting area; Installed at a high place (such as the corner between the indoor roof and the wall, the top of the outdoor lamp post), the position needs to meet: receive as much directional light emitted by the light source as possible, and the scattered light can cover the target lighting area; Fixed by an adjustable bracket (adjustment range ≥ 90°) to ensure that the light reflection direction can be adjusted as required.

[0008] When a concave mirror is used, it is necessary to ensure that its focal point is far above the ground, and its focal length l < h / 10, where h is the installation height of the concave mirror; Fitting relationship The light-emitting direction of the light source is directly opposite to the center of the mirror surface of the light distribution unit to ensure that as much directional light emitted by the light source as possible is received by the light distribution unit.

[0009] Convenient maintenance: The light source is installed at a low place, and it can be directly replaced without climbing heights. The operation threshold is low and it is suitable for various people (including the elderly and non-professionals); Enhanced safety: Avoiding working at heights fundamentally eliminates the risk of falling and reduces the safety accident rate during maintenance; Cost reduction: There is no need to call for height-climbing equipment, reducing the maintenance manpower and equipment costs of public lighting; Strong compatibility: It can directly transform the existing lighting system (such as replacing the light source at the top of the street lamp with a light distribution unit and installing a light source in the middle of the lamp post) without rebuilding the installation structure; Good durability: The light distribution unit is a convex mirror or a concave mirror, without vulnerable electronic components, has a long service life, and hardly requires maintenance.

[0029] The result after installation is shown in the image below. Figure 4 As shown. Working principle of the invention

[0030] This invention achieves maintenance without the need for climbing by separating the "light-emitting function" and the "light-distribution function" of the lighting system. The light source (at a low position) is responsible for directional light emission. Its core function is to provide a stable light source. Because it is easily damaged, it needs to be easy to replace. The lighting unit (high up) is responsible for light scattering. It uses the wide-angle reflection characteristics of the convex mirror to convert the directional light from the light source into scattered light that covers the lighting area, replacing the direct lighting function of the traditional light source. Because concave mirrors reflect light divergingly outside their focal point, they can still provide wide-angle reflection even when the illuminated area is far from the focal point. The two work together through the light propagation path: the directional light from the light source is focused on the mirror of the lighting unit, and after reflection, it evenly covers the target area, achieving the same lighting effect as traditional lighting devices, while also enabling maintenance of the light source without the need for climbing.
