Abstract
An illuminant device includes a housing, a illuminant element, a resistor, and an over-temperature protective element. The housing includes an upper portion, a lower portion opposite to the upper portion, and two accommodating spaces, respectively formed in a first tubular configuration arranged between the upper end and the lower end and a second tubular configuration spatially isolated from the first accommodating space. The illuminant element is placed on the upper portion. The resistor is located within one of the accommodating space and electrically connected to the illuminant element. The over-temperature protective element is located within the other accommodating space and electrically connected to the illuminant element.
