ABSTRACT:
A compact flash lamp array includes a housing defining a plurality of cavities, with each cavity having a light emitting opening and a combustible mass deposited in each cavity. A firing means such as an electrically heated filament or percussive primer is provided for individually firing the combustible mass in each cavity. Each cavity in the housing is provided with a porous portion communicating to the outside of the cavity having sufficient porosity to maintain cavity integrity during combustion of the combustible mass contained in a cavity while retaining combustion by-products.
