The balloon shade 2, as shown in FIG. 1 or FIG. 4, is fastened to the top side of the holder base 1, defining a recessed chamber 21 for receiving the balloon 6. The recessed chamber 21 can be made in a semispherical shape or any other shape; it can be isolated from the chamber 11 of the holder base 1 (see FIG. 1) or disposed in communication with the chamber 11 of the holder base 1 (see FIG. 4). The balloon shade 2 and the holder base 1 may be directly molded from plastics into one integral piece (see FIG. 8). Alternatively, the holder base 1 and the balloon shade 2 can be separately made and then fastened together with screws 22 (see FIG. 1) or by means of a plug joint 23 (see FIG. 4) or a screw joint 24 (see FIG. 6).
The balloon connector 3, as shown in FIG. 1, is fixedly mounted in the recessed chamber 21 inside the balloon shade 2, having at least one connecting portion 31 for securing the balloon 6. Preferably, as shown in FIG. 4, the balloon connector 3 is made in the form of a conical disk, and the connecting portion 31 is provided at the center of the conical disk and has a center hole 312 and a narrow notch 311 radially extending from the center hole 312 to the periphery (see FIG. 5). Thus, the balloon 6 can be fastened to the center hole 312 and the radial notch 311 of the connecting portion 31.
Further, the balloon connector 3, as shown in FIG. 1, is fixedly mounted in the recessed chamber 21 inside the balloon shade 2. The balloon connector 3 may be formed integral with or detachably fastened to the balloon shade 2 (see FIGS. 4 and 5). The balloon connector 3 can be made in the form of a conical disk and fastened with its one side to the inside of the recessed chamber 21 of the balloon shade 2. The arrangement of the balloon shade 2 and the balloon connector 3 may be variously embodied. According to the embodiment shown in FIGS. 13 and 14, the balloon connector 3 is formed integral with a part of the balloon shade 2, i.e., the balloon shade 2 has a narrow notch 32 radially and upwardly extending to the border edge, and a through hole 33 at the inner end of the narrow notch 32 for securing the balloon 6. According to the embodiment shown in FIGS. 6 and 7, the balloon connector 3 is provided with a weight 34 for securing the balloon to the recessed chamber 21 of the balloon shade 2. According to the embodiment shown in FIG. 8, the balloon connector 3 is detachably secured to the balloon shade 2, i.e., the balloon connector 3 has a ferrous block 35 fixedly secured thereto, and a magnetic member (magnet) 36 is set in the chamber 11 of the holder base 1 or the recessed chamber 21 of the balloon shade 2 to secure the ferrous block 35 of the balloon connector 3 by means of magnetic attraction. According to the embodiment shown in FIGS. 9 and 10, the balloon connector 3 is vertically movably secured to the balloon shade 2, i.e., the balloon connector 3 has a pull rod 37 vertically downwardly extending from its bottom side and inserted into the chamber 11 of the holder base 1 and a control member 371 extending out of the holder base 1 for operation by the user to move the pull rod 37 vertically upwards or downwards. According to the embodiment shown in FIGS. 11 and 12, a hinge 38 is used to hinge the balloon connector 3 to the balloon shade 2 inside the recessed chamber 21 and a torsion spring 381 is mounted in the hinge 38 to impart a pressure to the balloon connector 3 for holding the balloon connector 3 in position. By means of any of the aforesaid various mounting arrangement of the balloon connector 3, the installation of the balloon 6 is simple.
The LEDs (light emitting diodes) 4, as shown in FIG. 1, are mounted in the recessed chamber 21 of the balloon shade 2, and can be controlled or adjusted to emit light upon or through the balloon 6 (see FIG. 3) in a desirable manner. Preferably, the balloon shade 2 comprises a plurality of lamp holes 25 in the recessed chamber 21, and the LEDs 4 are respectively mounted in the lamp holes 25 and aimed at the balloon 6.

The power supply unit 5, as shown in FIG. 1, is mounted in the holder base 1 and electrically connected to the LEDs 4. The power supply unit 5 can be a DC power module (battery pack) to provide DC power to the LEDs 4 directly. Alternatively, the power supply unit 5 can be a power adapter that converts AC power supply into DC power supply for the LEDs 4.
Subject to the structural characteristics and space design of the aforesaid holder base 1, balloon shade 2, balloon connector 3, LEDs 4, power supply unit 5 and balloon 6, a balloon lamp is set up according to the present invention. To use the balloon lamp, as shown in FIG. 3, the balloon 6 is filled with a gas and then tied to the connecting portion 31 of the balloon connector 3 and received in the recessed chamber 21 of the balloon shade 2. When the power supply unit 5 is switched on to provide the necessary working voltage to the LEDs 4, the LEDs 4 are turned on to emit light toward the balloon 6, thus producing a lighting effect. Further, the low temperature and long working life of the LEDs 4 allow the balloon 6 to be arranged in proximity to the LEDs 4. Further, the arrangement of the balloon shade 2 and the balloon connector 3 facilitates mounting and dismounting of the balloon 6. The balloon lamp of the present invention is practical for use as a decorative item on a special occasion such as a wedding ceremony, a birthday party, etc., to create a unique atmosphere through the lighting effect.
Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
