1. What is The Underground Light?

Underground Light (Underground Light / Ground Buried Light / Recessed Light) is a lighting device embedded in the ground or building structure, mainly used for landscape lighting, building outlines, safety guidance and other scenes. Its core features are strong concealment, waterproof and durable, soft light, and are widely used in squares, parks, commercial buildings, courtyards and other places.

1.1 The difference between traditional and adjustable angle Underground lights.

Traditional underground lights usually adopt a fixed angle design, and it is difficult to adjust the irradiation direction after installation, resulting in the need to dismantle the lamp when the lighting effect needs to be changed, which is time-consuming and laborious. The underground lamp with externally adjustable angle has an innovative structural design, allowing users to adjust the light direction directly from the outside without disassembling the lamp, greatly improving the flexibility of use and maintenance convenience.

2. Appearance and structural design of adjustable angle underground lamps

(2.1) Appearance features

Adjustable angle underground lamps usually adopt a compact cylindrical or square design. The shell material is mostly die-cast aluminum or stainless steel. The surface is anodized or polished, and has IP67/IP68 high-level waterproof and dustproof performance. 

Its appearance features include:

• Rotatable shell: Some models adopt a rotating ring structure. Users can adjust the illumination angle of the internal LED lamp beads by rotating the shell.

• Hidden adjustment mechanism: The mechanical structure of gear + rack or thread + locking screw is adopted to ensure smooth and stable adjustment process.

• High light transmittance mask: The tempered glass or high-strength PC cover is used, which is anti-glare and has high light transmittance to ensure uniform light distribution.

(2.2) Internal adjustment mechanism

The core innovation of adjustable angle underground lamps lies in their external adjustable structure. Common designs include:

•Gear-driven rotating ring (such as Hangzhou Dingsheng patent): By rotating the rotating ring on the shell, the internal LED lamp holder is driven to rotate to achieve angle adjustment.

These designs allow users to adjust the lighting direction directly from the outside without removing the lamps, which is suitable for scenes that require frequent adjustment of the lighting angle.

3. Application scenarios of adjustable angle underground lamps

(3.1) Landscape lighting

• Garden landscape: used to illuminate trees, sculptures, flower beds, etc., and the layering of different landscapes can be highlighted by adjusting the angle.

• Commercial plaza: combined with the building outline, adjust the lighting direction to enhance the night vision effect.

(3.2) Architectural lighting

• Architectural outline: by adjusting the angle, the light is accurately projected onto the building facade to enhance the three-dimensional effect.

• Safety guidance: adjust the lighting angle in areas such as stairs and ramps to improve pedestrian safety.

(3.3) Stage and event lighting

• Temporary installation: in exhibitions, music festivals and other occasions, the lighting direction can be quickly adjusted to adapt to different stage layouts.

(3.4) Smart home and smart city

• Linkage with smart control system: some high-end models support DMX512 protocol or mobile phone APP control to achieve remote angle adjustment.

4. Technical advantages and market trends

(4.1) Technical advantages

• Disassembly-free adjustment: Traditional underground lamps need to be disassembled or reinstalled to adjust the angle, while adjustable models only need to rotate the shell or loosen the screws to complete the adjustment.

• Strong durability: The stainless steel gear + waterproof structure ensures that it is not easy to rust or loosen after long-term use.

• Cost optimization: Compared with the electric adjustment solution, the mechanical adjustment structure is more economical.

(4.2) Market trends

• Intelligent upgrade: Some manufacturers have launched electric adjustable underground lamps that support Bluetooth/Wi-Fi control, which may become the mainstream in the high-end market in the future.

• Modular design: The LED module or adjustment mechanism can be replaced to extend the service life of the lamp.

• Environmental protection and energy saving: The use of high-efficiency LED chips reduces energy consumption while improving lighting effects.

Led Underground lamps with externally adjustable angles solve the problems of fixed angles and inconvenient maintenance of traditional underground lamps through innovative mechanical structures. They are suitable for landscape lighting, architectural decoration, intelligent control and other scenarios. With the development of smart homes and smart cities, the market demand for this type of lamps will continue to grow. In the future, the electric adjustment + intelligent linkage solution may become more popular, providing users with a more convenient lighting experience.
