The illuminating device is flexible in arrangement and assembly, and is also more flexible in construction since the solar panels may be positioned at the highest portion to absorb more sunlight.
Description
- This application is a continuation of application Ser. No. 13/674,838 filed on Nov. 12, 2012, now pending, which is incorporated by reference herein in its entirety.
- Field of the invention
- The present invention is related to an illuminating device having folding solar panels mounted inside a lamp cover and, more specifically, an illuminating device that does not need an external power supply, but operates to store electricity and illuminate by means of electricity generated by solar energy.
- Background of the Invention
- One common illuminating device that uses solar energy for gardening or decoration purpose is as shown in
FIG. 1A . Such an illuminating device has asolar panel 91 provided outside alamp cover 93. However, such an arrangement occupies a lot of space and is unesthetic. Further, as thesolar panel 91 is exposed to outside the lamp cover, it is prone to be damaged by weather or inappropriate operation of user. Besides, as thesolar panel 91 is located at a lower altitude, it tends to be blocked by the surrounding plants or objects, and the power generating efficiency thereof is seriously affected. - To overcome the above defect, it has been suggested to incorporate the
solar panel 91 with thelight source 92 inside thelamp cover 93. Such arrangement may reduce the occupying space, and protect thesolar panel 91. However, as the volume of thesolar panel 91 increases, not only the volume of thelamp cover 93 has to be increased accordingly, but also theopening 931 for the access of the solar panel at the bottom of thelamp cover 93 has to be enlarged to an extent for allowing thesolar panel 91 to pass through. Accordingly, the volume of the illuminating device will be increased, and the base device mounted at the opening becomes bulky, giving an unaesthetic appearance to the lamp, which is disadvantageous to the gardening or decoration arrangement. - Therefore, it is an object of this invention to provide an illuminating device having folding solar panels mounted inside the lamp cover, which may significantly reduce the dimension of the opening of the lamp cover to allow the same solar panel to pass through, and yet do not have to compromise the working efficiency of the solar panel. Besides, the illuminating device according to this invention is esthetic in appearance, and is integral and flexible in construction. Further, as the solar panel is located at a higher altitude, it has more open space enable the solar panel to collect maximum sunlight.
- The illuminating device having folding solar panels according to the present invention comprises a lamp cover, a light source, at least two solar panels, and a folding holder.
- The lamp cover comprises an opening, a light source electrically connected to the lead line. The at least two solar panels are electrically connected to the light source. The folding holder comprises a bore through which the lead line of the light source passes. The at least two solar panels are disposed on the folding holder. The opening of the lamp cover is smaller than the deployed area of the folding holder. When it is intended to place the light source, solar panels, and folding holder inside the lamp cover, or to remove the light source, solar panels, and folding holder from the lamp cover, the folding holder is folded to form a predetermined angle therebetween so as to pass through the opening of the lamp cover.
- The folding holder according to the present invention may comprise at least two receiving seats pivotally connected to each other which are adapted to receive at least two solar panels.
- Preferably, the present invention comprises two solar panels, and the folding holder comprises two receiving seats. The two solar panels are connected in series or in parallel, and are electrically connected to an anode wire and a cathode wire, respectively. Each receiving seat includes a through hole through which the anode or cathode wire may pass. After the light source, solar panels, and folding holder have been placed inside the lamp cover, the anode wire and cathode wire are pulled downwardly towards the opening, so that the two receiving seats are stretched flat to lie horizontally.
- Accordingly, the folding holder according to the present invention may be inserted into the lamp cover in a folded pattern, and extend flat inside the lamp cover by pulling the anode wire and cathode wire of the solar panels, so that the solar panels may have a larger light absorption area.
- More preferably, the present invention may comprise a retaining sheet having at least two elastic supporting brackets and a central hole through which the lead line, anode wire, and cathode wire pass. The at least two elastic supporting brackets are disposed on the upper surface of the retaining sheet, and at least two elastic supporting brackets may urge against the inner wall surface of the lamp cover. Accordingly, the present invention may secure the light source and folding holder inside the lamp cover by means of the retaining sheet.
- More preferably, the present invention may further comprise a water-resistant gasket having grommet. The water-resistant gasket is arranged underneath the retaining sheet. The grommet is securely attached to the central hole of the retaining sheet which the lead line, anode wire, and cathode wire may pass in a fitting manner. Accordingly, the grommet is designed to tightly secure the lead line, anode wire, and cathode wire together, so that the light source, folding holder, and solar panels are securely fixed. The water-resistant gasket can effectively prevent the water from leaking through between the lamp cover and lower housing to jeopardize the electric circuit board and battery. Furthermore, the tight fit provided by the grommet of the water-resistant gasket is beneficial to secure the anode wire, cathode wire, and lead line of the light source, so as to maintain the folding holder in the substantially flat position, and to secure the light source on top of the solar panels.
- Furthermore, the folding holder of the present invention may comprise a base plate, and two U-shaped side walls which are arranged to oppose each other and extend vertically upwards from the base plate. The two U-shaped side walls are spaced from each other by a predetermined distance at the center portion of the base plate. Accordingly, the folding holder can be folded easily at the center portion where is absent in side wall.
