4. It comes with a CAUTION warning label indicating high voltage inside; only trained professionals should open the cover for maintenance, and self-disassembly is prohibited in daily use.
Scenario differentiation (compared to the previous waterproof model)
Table
This ultra-thin power supply (new model, real photo) – previously the deep blue IP6X7 waterproof power supply
Indoor scene applications: indoor door head light boxes, supermarket display window light boxes, indoor illuminated signs, exhibition hall lighting. Outdoor scene applications: outdoor billboards, exterior wall lighting, rainy and humid outdoor areas.
Using mesh cooling, no sealed or waterproof construction; cannot be exposed to rain or high-humidity dew conditions. Fully sealed housing with IP6.7 water resistance, capable of direct exposure to outdoor rain and dust.
Advantages: Slim design, suitable for light box cavities with smaller thickness; Advantages: Waterproof and dust-proof, better weather resistance in outdoor environments.
Adaptation project case studies (sub-topic real scenes that can be added on page 5 of the poster)
For this indoor model, case selection should avoid outdoor rain environments; the following real-life scenarios can be chosen:
1. Hanging ultra-thin light boxes on mall floors, backlight boxes in store windows
<t_XXXXXXXXX> <t_XXXXXXXXX>
2. Backlit illuminated signs on the storefronts of indoor shops, and LOGO signs for interior backgrounds of chain stores
<t_XXXXXXXXX> <t_XXXXXXXXX>
3. Indoor advertising light boxes within subway stations and high-speed train stations
<t_XXXXXXXXX> <t_XXXXXXXXX>
4. Light boxes within exhibition booths and indoor menu signs in dining establishments

5. Lighting and signage in the office lobby
Operational Precautions ⚠️
1. Load reservation: Daily load should be controlled at 75%-80% of the rated power (with a maximum of approximately 112W–120W) to extend the lifespan of the power supply.
<t_XXXXXXXXX> <t_XXXXXXXXX>
2. Environment installation: Place it in a well-ventilated area. Do not seal or wrap the casing to avoid blocking the honeycomb heat dissipation holes. This model should not be used in humid kitchens, bathrooms, or outdoor locations; switch to the IP6.7 waterproof version instead.
<t_XXXXXXXXX> <t_XXXXXXXXX>
3. Wiring standards: For the input power supply, L and N must be clearly distinguished; the negative terminal of the output should not be connected incorrectly. The terminal screws must be tightened to prevent loosening and arcing during construction.

4. When arranging multiple street lighting fixtures, ensure proper routing to minimize heat distribution
