Abstract

A light emitter at an umbrella head portion comprises a combining seat, an elastic switch, an light emitting element, a circuit board, a battery, and an elastic lampshade. The lower end of the combining seat is connected to the top of the main rib. The upper end of the combining seat is installed with a receiving chamber which receives the battery and the circuit board for providing power and a control circuit. A light emitting element is mounted above the circuit board, and at the outer ring of the elastic lampshade and the protruding ring at the outer periphery of the combining seat. As the elastic lampshade is pressed, the lampshade moves downwards so that the elastic switch of the lampshade transfers a current signal to the circuit board for actuating the control circuit to light up the light emitting element. If the elastic lampshade is further pressed, the light emitting element will be turned off.

Claims

1. A combined light emitter and umbrella comprising:

an umbrella having an axially extended umbrella shaft supporting an umbrella cloth;

a combining seat having a bottom end coupled to an upper end of said umbrella shaft adjacent and external to said umbrella cloth, said combining seat having an upper end formed with a receiving chamber therein and an outer periphery having a protruding ring portion;

a battery disposed in said receiving chamber;

a circuit board disposed in said receiving chamber and electrically connected to said battery;

a light emitting element mounted on said circuit board;

an elastic switch mounted to said circuit board and having a portion spaced from said circuit board for energizing said light emitting element responsive to a displacement of said spaced portion of said elastic switch into contact with said circuit board; and

,

an elastic lampshade overlaying said upper end of said combining seat and having an outer ring portion engaged with the protruding ring portion of said combining seat, said elastic lampshade forming a closure for said receiving chamber, a portion of said elastic lampshade being depressable to displace said spaced portion of said elastic switch and thereby selectively energize and de-energize said light emitting element.

2. The combined light emitter and umbrella as recited in claim 1, wherein said circuit board extends within said receiving chamber in a direction transverse said axial direction.

3. The combined light emitter and umbrella as recited in claim 1, wherein said circuit board extends axially within said receiving chamber.

4. The combined light emitter and umbrella as recited in claim 3, wherein said elastic switch is mounted to an end of said circuit board.

5. The combined light emitter and umbrella as recited in claim 1, wherein said spaced portion of said elastic switch is formed of conductive rubber.

6. The combined light emitter and umbrella as recited in claim 1, wherein said spaced portion of said elastic switch is formed by a portion of a helical spring.

7. The combined light emitter and umbrella as recited in claim 1, wherein said elastic lampshade has a fixing groove formed therein for receiving said spaced portion of said elastic switch therein.

8. A combined light emitter and umbrella comprising:

an umbrella having an umbrella shaft supporting an umbrella cloth;

a combining seat having a bottom end coupled to an upper end of said umbrella shaft adjacent and external to said umbrella cloth, said combining seat having an upper end formed with a longitudinally extended receiving chamber therein and an outer periphery having a protruding ring portion;

a circuit board extending longitudinally within said receiving chamber and electrically connected to said battery;

a battery mounted on said circuit board and electrically connected thereto;

a light emitting element mounted on said circuit board;

an elastic switch mounted to a longitudinal end of said circuit board adjacent a bottom end of said receiving chamber, said elastic switch having a portion thereof spaced from said circuit board for energizing said light emitting element responsive to a displacement of said circuit board into contact with said spaced portion of said elastic switch; and

,

an elastic lampshade overlaying said upper end of said combining seat and having an outer ring portion engaged with the protruding ring portion of said combining seat, said elastic lampshade forming a closure for said receiving chamber, a portion of said elastic lampshade being depressable to longitudinally displace said circuit board and thereby selectively energize and de-energize said light emitting element.
