What Is Lamp Fire (覆燈火) in BaZi?
Lamp Fire is the fire-class Nayin (a separate named element classification for a complete pair of chart symbols) assigned to 甲辰 and 乙巳. San Ming Tong Hui treats it as a human-made night light sustained by a wooden wick and oil, with detailed conditions for other pillars; the metaphor does not turn the whole chart into fire or prove intellect, visibility, or lifespan.
What does Lamp Fire establish first?
Lamp Fire is the Nayin name for a complete 甲辰 or 乙巳 pillar, and its Nayin phase is Fire. It may occur in the Year, Month, Day or Hour Pillar (the two-symbol column for the birth hour). The lookup unit is always one stem–branch pair in the same pillar, never a single character or a cross-pillar combination.
This lookup establishes one historical classification. 甲 remains a Wood stem and 辰 a Earth branch; 乙 remains a Wood stem and 巳 a Fire branch. Nayin Fire does not overwrite those ordinary Five-Phase facts.
How can you check for Lamp Fire?
Read each complete pillar in an already calculated chart. A pillar that is exactly 甲辰 or 乙巳 has the Lamp Fire Nayin. One matching character, a zodiac animal or a real-world object is insufficient.
| Complete Jiazi | Stem phase | Branch phase | Nayin name | Nayin phase |
|---|---|---|---|---|
| 甲辰 | Wood | Earth | Lamp Fire | Fire |
| 乙巳 | Wood | Fire | Lamp Fire | Fire |
Worked example: how should a 甲辰 Year Pillar be recorded?
Suppose the Year Pillar (the two-symbol column for the birth year) is 甲辰. The table returns Lamp Fire. A clear record says: Year 甲辰; stem 甲 is Wood, branch 辰 is Earth; Nayin is Lamp Fire, classed as Fire. This keeps the Nayin field separate from ordinary elemental data.
If 乙 appears only in the Month Pillar (the two-symbol column for the birth month) and 巳 only in the Day Pillar (the two-symbol column for the birth day), they do not form the same-pillar 乙巳 combination and do not create Lamp Fire. Complete pairing comes before image interpretation.
Why does the source use the name Lamp Fire?
San Ming Tong Hui calls this a human night light: wood serves as the wick and certain water images as oil. It distinguishes suitable supports from conditions associated with wind, flooding, or competing fire, and it evaluates exact additional pillars rather than every instance of wood or water alike. The passage also uses historical yin–yang time ranges and named special formations. Those details are interpretive conventions, not physical lamp mechanics or universal formulas. A responsible reading identifies the rule version and every matched pillar. Use the metaphor only with the source’s exact support conditions. Label historical time and formation conventions instead of modernizing them silently.
What value does Lamp Fire offer a modern reader?
Its practical value is precise lookup: 甲辰 and 乙巳 share this Nayin name, which lets you locate the pair’s distinctive source image and conditions. If another pillar enters an older rule, record that full Jiazi, its location and the source before drawing a comparison.
Keep the reading order explicit: verify calendar inputs and the Four Pillars; retain stems, branches and hidden stems; evaluate Month Command and Day-Master structure; only then add Lamp Fire as a Nayin layer. One Nayin name does not determine strength, Useful God, personality, work, relationships, wealth, health or event timing.
