Is a smart light bulb patented?

Short answer: specific designs of a smart light bulb have been patented many times, but "a smart light bulb" as a general idea is not what is protected. What matters is the exact combination of features in your version.

What our index shows
  • 140 US and WO patent publications since 2000 have a title matching “smart bulblamplighting” or a close variant (our index of 9.7 million patent families; one publication per family).
  • Among the 84 best keyword matches we examined, 37 were published in 2020 or later, and the earliest was published in 2005.
  • Most frequent assignees in those matches: XIAMEN ECO LIGHTING CO LTD (11), XIAMEN LEEDARSON LIGHTING CO LTD (6), SONY CORP (4), HORN DAVID (1).
  • Most common patent classes (CPC subclasses): H05B (45), F21V (41), F21Y (31), F21K (30).

Counts come from keyword matching on titles and abstracts, so they are indicative, not a legal count. Some matches are different products that share a word.

What this means for your idea

Because patents cover specific combinations of features, the useful question is not “has a smart light bulb been patented?” but “has my combination of features been described before?” Consumer electronics are among the most heavily patented areas; the specific circuit, mounting, or interaction is what distinguishes a design.
