Abstract

A lighting apparatus comprises at least one LED module, a light frame, a base plate, a battery, a cover plate, at least two end caps, and a fixture assembly. The base plate is received in the light frame. The LED module is mounted on the base plate. The battery is received in the light frame and electrically connected to the base plate. The cover plate is deposited on a bottom portion of the light frame. The end caps are assembled to two ends of the light frame. The fixture assembly serves to fix the lighting apparatus to a wall or a ceiling. When the lighting apparatus loses the external power supply, by operating a power switch connected to the lighting apparatus, the battery can be controlled to take over powering, with power stored therein, the LED module on the base plate to illuminate for a predetermined time period.

Claims18

Dependent claims

A lighting apparatus, comprising:

at least one LED module;
a light frame having a top portion, a bottom portion and a hollow portion, wherein the top portion is provided with a pair of corresponding lengthwise grooves while the bottom portion is provided with a recessed accommodating space and another pair of corresponding lengthwise grooves;
a base plate allowing the LED module to be such installed thereon that the base plate is received in the accommodating space of the light frame and the LED module faces an opening of the accommodating space;
a cover plate deposited on the bottom portion of the light frame and inlaid in the lengthwise grooves of the bottom portion;
a battery received in the hollow portion of the light frame;
a power control module located in the hollow portion of the light frame and electrically connected with the base plate and the battery, respectively, wherein the power control module is connected to an external grid power source so that when the grid power source is down, the power control module automatically uses the battery to take over powering the LED module for emergency illumination;
and
at least two end caps assembled to two ends of the light frame so as to enclose the base plate on which the LED module is fixed in the accommodating space of the light frame and enclose the battery in the hollow portion of the light frame.

5 more elements

A lighting apparatus for being installed onto a lamp holder, the lighting apparatus comprising:

at least one LED module;
a light frame having a top portion, a bottom portion and a hollow portion, wherein the bottom portion is provided with a pair of corresponding first grooves and a pair of corresponding second grooves;
a base plate allowing the LED module to be installed thereon and inlaid in the first grooves at the bottom portion of the light frame so as to place the LED module below the light frame;
a cover plate deposited on the bottom portion of the light frame and inlaid in the second grooves;
a battery settled in the hollow portion of the light frame;
a power control module settled in the hollow portion of the light frame and electrically connected to the base plate and the battery, respectively, for voltage transformation and current rectification;
and
at least two joints assembled to two ends of the light frame, each having two conducting pins and electrically connected to the power control module, and serving to enclose the base plate in the cover plate and enclose the battery in the hollow portion;
wherein, when assembled together, the light frame and the cover plate jointly form a round tubular shape.
