DETAILED DESCRIPTION

[0028] With reference to FIGS. 1-11, a lamp structure of an umbrella according to a preferred embodiment of the present invention comprises a body 10, an illumination device 20, and a control pusher 30.

[0029] The body 10 includes a shaft 11, a notch 12 fixed on a top of the shaft 11, a runner 13 slidably fitted on the shaft 11 and located below the notch 12, and multiple stretchers 14 rotatably connected with the notch 12 and the runner 13, wherein the shaft 11 includes two connection orifices 111 oppositely defined adjacent to a top of the shaft 11, the notch 12 includes a cap 121 removably screwed thereon, the runner 13 includes two grooves 131 and two longitudinal slots 132 which are defined on a peripheral side of the runner 13, a shoulder 133 extending proximate to a bottom of the peripheral side of the runner 13, a through orifice 1311 formed on a middle portion of a respective one groove 131, and two flexible retainers 134 mounted on the two grooves 131 and being arcuate, wherein a respective one flexible retainer 134 has a locking section 1341 extending inward from a middle thereof, such that the locking section 1341 of the respective one flexible retainer 134 corresponds to the through orifice 1311 of the respective one groove 131, and the locking section 1341 of the respective one flexible retainer 134 is engaged with the a respective one connection orifice 111 of the shaft 11. Also, the multiple stretchers 14 are configured to support a cloth (not shown).

[0030] The illumination device 20 is connected with a lower end of the notch 12, as shown in FIG. 12, the illumination device 20 includes at least one lighting element 21, a circuit board 22 configured to control the at least one lighting element 21 to operate or not, and a battery 23 configured to supply power to the at least one lighting element 21, wherein the circuit board 22 has a control switch 221. In this embodiment, the control switch 221 is a reed switch. When the runner 13 is moved upward to push the illumination device 20, the umbrella is opened. When the runner 13 is moved downward to remove from the illumination device 20, the umbrella is closed. The illumination device 20 includes an accommodation chamber 24 defined therein and an opening 241 upward passing through the notch 12, such that the battery 23 is received in the accommodation chamber 24 from the opening 241, and the cap 121 is screwed on the upper end of the notch 12 to close the accommodation chamber 24. The at least one lighting element 21 is mounted on a light-emitting strap 25, and the light-emitting strap 25 is spirally surrounded by the illumination device 20.

[0031] The control pusher 30 is in a circular tube shape and is connected to the runner 13. The control pusher 30 includes a flange 31 extending from a middle section of an inner wall thereof, two slidable blocks 32 formed above the flange 31, two first positioning protrusions 33 oppositely extending below the flange 31, two second positioning protrusions 34 oppositely extending below the two first positioning protrusions 33, and a controlling element 35 extending upward from a side of the control pusher 30. In this embodiment, the controlling element 35 is a magnet and corresponds to the control switch 221, such that the two slidable blocks 32 are slidably received in the two longitudinal slots 132 of the runner 13 to limit the control pusher 30 to slide vertically with respect to the runner 13, and the flange 31, the two first positioning protrusions 33 and the two second positioning protrusions 34 are engaged by the shoulder 133 of the runner 13 to be switched in three-section positions, for example, the control pusher 30 is slid to a first position 30A, a second position 30B, and a third position 30C relative to the shaft 11.

[0032] When closing the umbrella, as shown in FIGS. 4 and 5, the control pusher 30 is located at a third position 30C, the flange 31 of the control pusher 30 is engaged by the shoulder 133 of the runner 13, the controlling element 35 and the control switch 221 move away from each other and do not drive the control switch 221 to conduct, the circuit board 22 controls the at least one lighting element 21 to power off, wherein the control pusher 30 and the runner 13 slide vertically along the shaft 11. Referring to FIGS. 6-8, when the umbrella is used in a dark environment, the runner 13 is slid upward to push the illumination device 20 to be in an opening state, so the control pusher 30 is pushed upward to be switched to the first position 30A, the two first positioning protrusions 33 of the control pusher 30 are pushed by the shoulder 133 of the runner 13, the controlling element 35 and the control switch 221 move close to each other to drive the control switch 221 to be conducted so that the circuit board 22 controls the at least one lighting element 21 to power on, and the at least one lighting element 21 illuminates light from top to bottom (as illustrated in FIG. 13), thus increasing illumination range and effect and emitting a user to make a warning effect.

[0033] With reference to FIGS. 9-11, when the umbrella is used in a bright environment, the runner 13 is slid upward to push the illumination device 20 to open the umbrella so that the control pusher 30 is pushed downward to be switched to the second position 30B, wherein the two second positioning protrusions 34 of the control pusher 30 are engaged by the shoulder 133 of the runner 13, the controlling element 35 and the control switch 221 move away from each other to stop conducting the control switch 221 so that the circuit board 22 controls the at least one lighting element 21 to power off, thus avoiding compunction of the power.

[0034] Thereby, the lamp structure of the umbrella has advantages as follows: [0035] 1) The illumination device 20 is connected to the lower end of the notch 12, and the control pusher 30 is connected to the runner 13, wherein the control switch 221 of the illumination device 20 is driven by the controlling element 35 of the control pusher 30 to be conducted or not, such that the at least one lighting element 21 is power on or off, so electrically connecting a wire in the shaft 11 is eliminated to obtain quick assembly, low failure rate, modularization, and easy connection. [0036] 2) When the umbrella is opened, the control pusher 30 is switched to the first position 30A to control the at least one lighting element 21 to power on, thus emitting the lights below the umbrella and making a warning effect. Also, when the umbrella is opened, the control pusher 30 is switched to the second position 30B to control the at least one lighting element 21 to power off, thus obtaining using convenience, aesthetic appearance, and gripping comfort.
