Abstract

An emergency light includes a housing having a lamp and having also a battery for energizing the lamp. A smoke-proof mask is disposed in the housing and includes a filter for filtering smoke and means for allowing user the to find the mask easily and quickly. A buzzer may be coupled to the battery for indicating to a blind user where to find the smoke-proof mask easily and quickly. The battery is a rechargeable battery and is coupled to a sensing/switching circuit which may switch the battery to energize the lamp when the AC power supply is not supplied to the sensing/switching circuit.

Claims

1. A light combination comprising:

a portable housing including a chamber,

a lamp pivotally secured to said housing,

at least one battery secured in said housing and coupled to said lamp for energizing said lamp,

a smoke-proof mask disposed in said chamber of said housing for allowing a user to find the mask easily, said smoke-proof mask including a filter for filtering smoke and including a mask body coupled to said filter, and

means for securing said filter directly to said on an inside surface of said chamber housing.

2. A light combination according to claim 1 further comprising means for attaching said smoke proof mask to the user.

3. A light combination according to claim 1 further comprising a buzzer coupled to said battery for allowing said buzzer to a blind user where and to indicate to the blind user to find the smoke-proof mask.

4. A light combination according to claim 1, wherein said battery is a rechargeable battery, said light combination further a charge circuit coupled to said rechargeable battery for charging said rechargeable battery, a sensing/switching circuit coupled to a power supply and also coupled to said rechargeable battery and to said charge circuit, said rechargeable battery and said lamp being coupled to said sensing/switching circuit, said sensing/switching circuit being coupled between said power supply and said charge circuit for sensing the power supply to said sensing/switching circuit and for switching and coupling said rechargeable battery to said lamp and for energizing said lamp when the power supply is not supplied to said sensing/switching circuit.
