Description

  The present invention relates to a lamp shade structure applied to a working lamp, and in particular, uses a heat-dissipating fan of the working lamp, blows it into a soft lamp shade and inflates it at the time of implementation, or can create a totally translucent lamp shade or a downward reflecting lamp The present invention relates to an air-filled lamp shade of a working lamp capable of enhancing ground lighting as a shade.

  In general, at construction sites or outdoors, a lack of light in the indoor or night environment adversely affects safety. For this reason, working personnel use work lamps, spotlights, and the like to provide sufficient lighting to facilitate the smooth progress of work.

  The inventor once developed an LED lighting device disclosed in Patent Document 1. As shown in FIG. 1, the lighting device has a stand and a light emitting assembly 1 installed on the stand. The light emitting assembly 1 includes a lamp support frame 2 installed on a stand, a plurality of LED light emitting plates 3 installed so as to surround the lamp support frame 2, and a heat dissipation fan 4 installed below the lamp support frame 2. The heat dissipating fan 4 can blow air upward to the back side of each LED light-emitting plate 3, thus forcibly cooling. The plurality of LED light-emitting plates 3 can be used as work lamps at a disaster recovery site, a construction site, etc. by adjusting the irradiation angle on the lamp support frame 2 and further making the stand correspond.

  In the prior art, measures have been taken to avoid problems such as excessive concentration of light projected by the light emitting assembly, causing vision loss for workers during night use, and crashing and damage. As disclosed in Patent Literature 2, Patent Literature 3, and Patent Literature 4, an air-filled soft lamp shade is installed on the outer periphery of the light emitting assembly. When used as a work lamp, the light is uniformly diffused outward to avoid a situation such as collision and damage, and the work lamp can be conveniently stored when not in use.

  The conventional air-filled soft lampshade described above has no particular problem in use. However, when the structure of the conventional air-filled soft lampshade is studied in detail, the light beam of the conventional technology is uniformly diffused in all directions, but is uniform in the same direction. It was found that was not irradiated. For example, when a worker is working on the ground and the work illumination on the ground has to be strengthened, the light rays projected upward will disperse the light intensity.

  Furthermore, since the lamp shade disclosed in Patent Document 3 forms a drum shape after air filling, the structure is composed of three upper, middle, and lower cloths. The process of connecting the three cloths is not easy and the manufacturing process is complicated. Thus, there is a need to facilitate the manufacture and use of this type of soft lampshade.

The lamp shade top is sealed, and the bottom is provided with an opening to cover the outside of the lamp support frame of the work lamp. When the light emitting assembly of the working lamp is in operation, the heat dissipating fan of the light emitting assembly blows from below the opening at the bottom of the lamp shade, and the lamp shade 100 swells and has a generally spherical shape. The lamp shade has two soft upper cloth pieces and lower cloth pieces that have a circular shape corresponding to each other, and a plurality of tooth shapes arranged at intervals around the upper cloth piece and the lower cloth piece. Each of the adjacent tooth-shaped notch edges is connected to each other, thereby forming a solid arc curved surface whose peripheral edge is curved downward on the upper cloth piece. A solid arcuate curved surface whose peripheral edge is curved upward is formed on the piece, and the lower edge of the upper cloth piece and the upper edge of the lower cloth piece are connected correspondingly. An opening is further installed in the center of the lower cloth piece. The opening has a circular hole, and the side of the circular hole can be closed or opened, thereby covering the lamp shade outside the lamp support frame. Opening and closing parts are installed, and a bundled belt that surrounds the lamp support frame and is positioned is installed on the inner edge of the circular hole so as to be removable.

  Due to the above-described structure, the lamp shade is relatively easy to manufacture because the upper cloth piece and the lower cloth piece are connected to each other and has a substantially spherical shape, and the lamp shade can be quickly passed through the opening of the lower cloth piece. Since it is fixed on the lamp support frame, the combination is very easy.

The implementation method of each part is demonstrated below.
At the time of implementation, both the upper cloth piece and the lower cloth piece are made of a translucent material to form a totally translucent lamp shade, or the inner bottom surface of the upper cloth piece is a non-translucent reflective layer and the lower cloth piece is translucent. The material, whereby the light of the light emitting assembly is reflected by the reflective layer and then irradiated downwards, forming a downward reflective lampshade, thus enhancing the ground illumination.

  At the time of implementation, a plurality of localization belts extending downward and hanging on the lamp support frame are further provided on the inner bottom surface of the upper cloth piece.

  At the time of implementation, one end of the stereotactic belt is fixed to the inner side of the upper cloth piece, the opposite end can be folded back and fixed on the lamp support frame, and the stereotactic belt can be folded at one end of each stereotactic belt that can be folded back. Install fitting parts or hook-and-loop fastener parts that can be fixed later. Even when air is filled and blown through the installation of the plurality of localization belts, the lamp shade does not touch and move stably, and the influence on the lighting effect due to the shaking of the light beam can be avoided.

  At the time of implementation, a converging belt that converges after the air of the lamp shade is removed is installed outside the upper cloth piece or the lower cloth piece.

  At the time of implementation, at least one vent hole is provided below the lower cloth piece, and thereby the air flow flowing into the lamp shade is discharged from the vent hole.

  In practice, the opening and closing part is a zipper or a hook-and-loop fastener belt.

  The lamp shade according to the present invention connects the upper cloth piece and the lower cloth piece and has a substantially spherical shape. Therefore, the lamp shade is easier to manufacture than the conventional technique of combining the upper, middle and lower cloths, and the production cost is reduced. The upper cloth piece and the lower cloth piece are both made of a translucent material to form a totally translucent lamp shade, or the inner bottom surface of the upper cloth piece is an opaque translucent layer and the lower cloth piece is made of a translucent material.
