Portable light up mirror

1. A portable light up mirror, comprising:

a mirror element;

a case element, wherein said mirror element is mounted in said case element;

a cover element which is coupled with said case element for covering said mirror element;

a light source which is arranged behind said mirror element within said case element, wherein said mirror element comprises a substrate layer and a reflective layer, wherein said substrate layer is a transparent layer comprising a maid body and an edge portion integrally extended from said main body to surround said main body, wherein said reflective layer is attached to said substrate layer, wherein said edge portion of said substrate layer comprises a blasted surface for diffusing light beams from said light source, wherein said case element comprises a base board, a mounting frame connected to said base board, and a surrounding wall connected to said base board, wherein an accommodating groove is formed between said mounting frame and said surrounding wall, wherein said light source comprises a flexible circuit board and a plurality of light emitting elements attached on said flexible circuit board, wherein said flexible circuit board and said plurality of light emitting elements are disposed in said accommodating groove, wherein each of said light emitting elements comprises a light emitting surface oriented toward said surrounding wall of said case element and a side edge oriented toward said mirror element, so as to allow light beams from each said light emitting element to project onto said surrounding wall of said case element and then are reflected by said surrounding wall towards said edge portion of said substrate layer of said mirror element, wherein said reflective layer comprises a peripheral edge which is extended to a position above said accommodating groove in a manner that said plurality of light emitting elements are covered by said peripheral edge of said reflective layer, so as to hide said light emitting elements behind said peripheral edge of said reflective layer; and

a control unit which is electrically connected to said light source to control operation of said light source, wherein said control unit comprise a circuit board which is integrated with a capacitive touch controller chip, and a capacitive sensing element which is electrically connected to said capacitive touch controller chip to detect a finger touch of a user;

wherein said capacitive sensing element comprises an sensing layer attached to said mirror element and a spring abutting against said sensing layer, wherein said spring is an electrical conductor that is electrically connected to said circuit board, wherein said case element comprises a mounting pin which is extended from said base board, and said spring is wound around said mounting pin in a manner that said mounting pin retains said spring in position.

2. The portable light up mirror, as recited in claim 1 , wherein said sensing layer is a round copper foil that is attached to a back side of said mirror element, wherein a diameter of said sensing layer is larger than a diameter of said spring, wherein when a finger of the user approaches said mirror element at a position corresponding to said sensing layer, the finger disrupts electromagnetic field around said capacitive sensing element and cause a change in capacitance, and this change is detected by said capacitive touch controller chip, so as to trigger an operation of said light source from one of activating said light source, turning off said light source and adjusting illumination intensity of said light source.

3. A portable light up mirror, comprising:

a mirror element;

a case element, wherein said mirror element is mounted in said case element;

a cover element which is coupled with said case element for covering said mirror element;

a light source which is arranged behind said mirror element within said case element, wherein said mirror element comprises a substrate layer and a reflective layer, wherein said substrate layer is a transparent layer comprising a maid body and an edge portion integrally extended from said main body to surround said main body, wherein said reflective layer is attached to said substrate layer, wherein said edge portion of said substrate layer comprises a blasted surface for diffusing light beams from said light source, wherein said case element comprises a base board, a mounting frame connected to said base board, and a surrounding wall connected to said base board, wherein an accommodating groove is formed between said mounting frame and said surrounding wall, wherein said light source comprises a flexible circuit board and a plurality of light emitting elements attached on said flexible circuit board, wherein said flexible circuit board and said plurality of light emitting elements are disposed in said accommodating groove, wherein each of said light emitting elements comprises a light emitting surface oriented toward said surrounding wall of said case element and a side edge oriented toward said mirror element, so as to allow light beams from each said light emitting element to project onto said surrounding wall of said case element and then are reflected by said surrounding wall towards said edge portion of said substrate layer of said mirror element, wherein said reflective layer comprises a peripheral edge which is extended to a position above said accommodating groove in a manner that said plurality of light emitting elements are covered by said peripheral edge of said reflective layer, so as to hide said light emitting elements behind said peripheral edge of said reflective layer; and

a control unit which is electrically connected to said light source to control operation of said light source, wherein said control unit comprise a circuit board which is integrated with a capacitive touch controller chip, and a capacitive sensing element which is electrically connected to said capacitive touch controller chip to detect a finger touch of a user;

wherein said mirror element comprises a substrate layer, a reflective layer attached to said substrate layer, and an indication pattern which is distinguishable from said substrate layer and achieved through laser etching a glass material of said substrate, so as to be aligned with said capacitive sensing element to signify a finger touch area of said mirror element, wherein said reflective layer is positioned between said capacitive sensing element and said indication pattern.
