Description

The present invention relates to a reading light.

Illumination light sources such as a reading light and a bed light include an arm type or a flexible arm type on a pedestal having a flat bottom surface, and a head portion that can be rotated or a wall-mounted type.

However, illumination light sources such as reading lights and bed lights can only be placed on a desk or other designated place, and when moving the reading place, you must find the place where the light is placed and the position of the outlet. However, there is a concern that the power cord will fall over.

  A reading light that does not fall down when you touch it without having to choose a place to place it, and it is foldable and convenient to carry

  The bottom surface has a hollow hemispherical shape, a magnet is provided at the center of the inner surface of the hollow hemispherical shape, and the body has a bellows-like truncated cone shape that can freely expand and contract. A hollow and transparent substantially spherical shade is provided on the upper surface of the truncated cone, and an annular flat portion is provided at a right angle with respect to the side of the truncated cone body around the upper surface of the truncated cone body and the substantially spherical shade. The light emitting member inside the flat portion can irradiate along the outer surface portion of the truncated cone body, and the light emitting member can irradiate a substantially spherical periphery on the hollow and transparent substantially spherical shade top. Also, by using a desktop holder with a charger when stable light irradiation is required for long periods of use, such as by placing it on the side of a computer, the hemispherical bottom surface of the main body can be placed stably. It can also be charged.

By providing a magnet that acts as a weight in the center of the inner surface of the hollow hemispherical body and returns to its original shape due to the shape of the bottom surface, the weight, and the balance of the body even if it falls down Can do. There is no worry about falling down even if you place it around your hand, such as when you work by hand. Moreover, since it is cordless, it can also be used outdoors. As a method of outdoor use, the light emitting member on the inner surface of the roughly spherical shade illuminates a certain area of the place where the main body is placed along the slope around the frustoconical fuselage, the role of the surrounding illumination and flashing warning light, and both By turning on simultaneously, a double effect can be obtained. By installing illumination light sources such as illuminating lights and warning lights, light distribution suitable for the purpose of use can be achieved.

FIG. 1 is a front view of the entire main body. A hollow hemispherical bottom surface A and an upper part of the bellows-shaped truncated cone body B indicate the head portion of the substantially spherical shade E.

FIG. 2 is a cross-sectional view of the entire main body. A magnet is provided at the center of the inner surface of the hollow hemispherical bottom surface A as the weight A-a, and the substantially spherical shade E can maintain the upper position of the main body by the hemispherical A and the weight Aa on the bottom surface. It is preferable to adjust the weight of the magnet A-a.

The hemispherical upper surface opening of the bottom surface A of the hollow hemispherical body is connected to the lower side of a telescopic bellows-conical body B that can be expanded and contracted, and the bellows-type body B not only adjusts the overall length but also as shown in FIG. When the head portion C is directed obliquely downward, the head portion lower irradiation light source F can irradiate oblique light. By doing so, for example, it can be used to irradiate oblique light on a keyboard when placed on the side of a personal computer.

The length of the bellows-shaped body B is related to the balance of the overall weight, and the length when it is stretched every time needs to be constant. It is connected to the center Bb of the upper surface of the truncated cone body (see the figure). By doing so, the elongation of the bellows body B can be made constant at all times, and excessive elongation can be prevented.

The position of the battery case Ac for power supply of the light emitting unit at the top of the main body is provided at the height of the circular center of the bottom hemisphere A, that is, the position of the bottom of the truncated cone, for example, when the main body is in a horizontal state, The edge around the above-mentioned hemispherical upper surface opening serves as a fulcrum of the entire main body, but the battery case is also located at the fulcrum at the same time, so that the weight of the magnet Aa does not interfere with the main body.

The electric cord of the battery case Ac is connected to the light source part of the upper surface of the main body along the string Ba connected to the bottom center Ab and the truncated cone upper surface center Bb, and the electric cord is disturbed when the bellows-shaped body B expands and contracts. Make it so that it does not wrap around the string Ba.

Fig. 3-1 is a perspective view of the bellows-shaped truncated cone body B. Fig. 3-2 is a perspective view of a hollow hemispherical bottom surface A.

FIG. 4 is a front cross-sectional view of each member disassembled from the light emitting portion of the main body upper substantially spherical shade. By forming a cylindrical ring shape around the flat part of the upper surface of the truncated cone (see the figure), the circular cylindrical shape of the dish and the transparent substantially flat circular shape shown in FIG. The cylindrical annular portion at the bottom of the member C can be fitted.

The light emitting member installation base D shown in FIG. 4B is a combination of a substantially hemispherical shape and a substantially planar annular shape, and the hollow and the lower portion are formed by integrating a cylindrical annular shape, and the lower cylindrical annular portion is formed. Can be fitted with the transparent substantially planar annular member C. When the LED light-emitting member G is provided in a ring shape on the outer surface of the substantially hemispherical shape of the light-emitting member installation base D as viewed from above, and the LED light-emitting member G protrudes from the outer surface of the substantially hemispherical shape, light emission occurs. The member G can be irradiated in a substantially spherical shape (see the figure).

An annular light emitting member F is provided on the reflective surface with the annular lower surface portion as a reflection surface on the substantially planar annular lower surface portion of the light emitting member installation table D. The ring-shaped light emitting member F can irradiate along the inclined surface of the truncated cone body B through the transparent substantially flat ring portion C with the dish portion on the upper surface of the body being fitted (see the figure). The transparent hollow substantially hemispherical shade E covers the light emitting member mounting base D and is connected to the edge of the substantially hemispherical opening and the edge of the plane annular ring of the transparent substantially planar annular member C, thereby emitting light. The whole part has a substantially spherical shade shape (see figure).

FIG. 5 is a perspective view of each member disassembled from the light emitting portion of the substantially spherical shade. FIG. 6 is an overall perspective view of the main body. FIG. 7 shows the light emitting part of the upper spherical body of the main body in the form of obliquely downward irradiation. The annular light emitting member F can be irradiated not only obliquely on the truncated cone body B but also obliquely downward.

8A is a perspective view of the desktop holder H. FIG. 8B is a front sectional view of the desktop holder H. FIG. The desktop holder H can be used to stabilize the hemispherical bottom of the main unit when it needs stable light irradiation for long periods of use, such as by placing it on the side of a computer, and also has a charger. Since it is a cylindrical ring-shaped desktop holder H, it can be charged with the main body mounted.
