Faktisk, varmemotstanden til eksplosjonssikre lys har sine begrensninger. For eksempel, if a light’s casing can withstand temperatures up to 135°C, betyr det at den tåler høy varme? That’s not necessarily true because the solder inside the light beads has a much lower temperature tolerance. Hvis temperatur exceeds 100°C, the beads might fall off. Derfor, the casing temperature does not represent the internal temperature of the light, which is typically around 80°C.
In high-temperature environments like boiler rooms and paint baking rooms, boiler rooms generally don’t pose a problem, but paint baking rooms are definitely unsuitable.
