Special Lighting for Mobile Toilets

Special lighting for mobile toilets must meet the CJJ 14-2016 standard, with core requirements including illuminance, light source, protection rating, and emergency systems. The selection of lighting fixtures should be based on scenario needs, and installation must comply with safety regulations.

1. Lighting Standard Requirements

According to CJJ 14-2016, Design Standard for Urban Public Toilets, the illuminance in different areas of mobile toilets must meet the following standards: 150-200 lx for handwashing areas, 100-150 lx for toilet areas, and 75-100 lx for corridors. The light source should be LED fixtures with a fixed color temperature of 4000K and a color rendering index of ≥80 to ensure soft lighting and high color accuracy. Lighting fixtures must have a waterproof rating of IP65 or higher to withstand dust intrusion and low-pressure water jets, making them suitable for outdoor environments. Additionally, an emergency lighting system must be installed, capable of providing continuous power for 90 minutes after a power outage to ensure safe evacuation during emergencies.

2. Lighting Fixture Selection

1. Solar-Powered Lighting: Suitable for outdoor scenarios without power access, such as solar motion-sensing lights (priced at 60-3200 yuan/set). Their advantages include motion-sensing functionality (lights turn on when people approach and turn off after a delay), waterproof and dustproof capabilities (IP65 or higher), and no need for wiring, reducing construction costs.
2. LED Ceiling Lights: Standard LED ceiling lights for toilets are relatively inexpensive (10-47 yuan/unit), but it is crucial to verify that their waterproof rating meets IP65 requirements to prevent damage from water ingress.
3. Smart-Controlled Lighting: Supports automatic motion-sensing switching and automatic illuminance adjustment, such as dynamically adjusting brightness based on ambient light intensity, enhancing energy efficiency and user experience.

3. Installation Guidelines

1. Safety Principles: Prioritize the use of low-voltage LED fixtures (e.g., 12V or 24V) to minimize the risk of electric shock from the source. Electrical connections should be wrapped with multiple layers of insulating tape and waterproofed to prevent short circuits in humid environments.
2. Protection Rating Verification: Before installation, check the IP protection rating markings on the fixtures to ensure they meet IP65 or higher standards, preventing failures caused by rain or dust intrusion.
3. Basic Steps: Include fixture mounting (using expansion screws or dedicated brackets), wiring connections (avoiding exposed wires), and switch installation (preferably waterproof switches or remote-controlled switches). After installation, conduct a 30-minute trial run to observe whether the fixtures turn on and off normally, without flickering or unusual noises, and confirm no faults before putting them into use.

4. Market Supply and Procurement Recommendations

Suppliers of solar-powered toilet lights include Changzhou Aiyidi Lighting Technology Co., Ltd. and Langfang Bode Energy-Saving Technology Co., Ltd., among others, with product prices varying significantly based on power and configuration (60-3200 yuan/set). For comprehensive solutions, consider the leasing services of Shanghai Weize Environmental Protection Engineering Equipment Co., Ltd., which often integrates lighting systems with emergency lighting and smart control modules for one-stop procurement. During procurement, it is essential to verify that products have passed CCC certification and request IP65 test reports from suppliers to ensure compliance.
