TRIAC dimming is applied toblackboard luminaires, and under the current classroom lighting, especially theGB 7793-2025new requirements context, it offers clear practical and product-upgrade advantages, mainly in the following aspects:
1. Fully complies with the new national standard requirements for blackboard luminaires
GB 7793-2025 explicitly states:
"In ordinary classrooms using multimedia teaching, each blackboard lighting luminaire shall be equipped withan independent dimming or illuminance-reduction control device."
The advantages of TRIAC dimming are:
- ✔ Each luminaire can be controlled independently, without the need for a centralized control system
- ✔ Enables multi-level adjustment such as "full on / reduced illuminance / off"
- ✔ Satisfies the explicit determination of "independent dimming" during acceptance inspection
👉 For school acceptance, tender technical clausesFriendly and intuitive.
II. Ideal for "multimedia + blackboard writing" teaching scenarios
In actual teaching, blackboard lighting has typical usage scenario switching:
| Teaching scenario | Requirements for blackboard lighting |
|---|---|
| Traditional blackboard writing | High illuminance, uniform, glare-free |
| Projection/electronic whiteboard | Dim or turn off blackboard lighting to avoid reflection |
| Blended teaching | Local dimming to ensure visibility |
Advantages of TRIAC dimming:
- 🔹 Instant response, dim with a knob or one-touch panel control
- 🔹 Does not affect other luminaires in the classroom
- 🔹 Extremely low operating cost for teachers
III. Simple system, low retrofit and implementation cost
Compared with dimming methods such as 0–10V and DALI, the advantages of TRIAC dimming for classroom whiteboard lights are very obvious:
Comparative advantages
| Item | TRIAC dimming |
|---|---|
| Wiring | No additional control wires |
| Installation | Similar to ordinary switches |
| Construction difficulty | Low |
| Old classroom retrofit | Extremely friendly |
| Cost | lower than intelligent dimming systems |
👉 Very suitable for old school building lighting renovation projects, this is a key focus for many education bureaus.
IV. Continuous dimming, no flicker, good for eye protection
High-quality TRIAC dimming + dedicated dimming driver, on blackboard lights can achieve:
- ✔ Smooth dimming process, no obvious jumps
- ✔ Under low illuminanceNo visible flicker, no sense of fluctuation
- ✔ Does not affect color rendering index, stable color temperature
For students:
- Reduce blackboard glare
- Reduce visual fatigue from staring at the blackboard for long periods
This is a great bonus for "eye-protection lighting" promotion, especially suitable for upgrading your existing eye-protection light product line.
V. High reliability, simple later maintenance
TRIAC dimming technology is mature, suitable for long-term, high-frequency use environments like schools:
- 🔧 Simple structure, few failure points
- 🔧 Does not rely on complex control systems
- 🔧 Easy to replace, readily accepted by teachers
Compared with smart systems:
- No risk of "control module failure rendering the entire luminaire unusable"
- Low later-stage operation and maintenance costs, high acceptance by schools
Six, conducive to product differentiation
By adding to the writing board luminaireTRIAC independent dimming function, can directly form:
- ✅ "Compliant with the new GB 7793-2025 standard"
- ✅ "Dedicated writing board luminaire for multimedia teaching"
- ✅ "Independent dimming · more eye-friendly teaching"
Seven, one-sentence summary
TRIAC dimming writing board luminaireIt enables independent dimming of each luminaire without a complex system, perfectly suited to multimedia teaching scenarios and compliant with the new GB 7793-2025 standard requirements, reducing glare and protecting eyesight, making it an ideal choice for eye-friendly classroom lighting.
