Therefore, no step is formed between the extended portion 30B and the light portion 4, and a uniform and clean irradiation space 5 without shadows due to unevenness or the like is formed between the stand portion 3 and the light portion 4. In addition, design unification is planned.

A shaft portion 38B for pin connection with the light portion 4 is provided at an end portion 36 of the extension portion 30B facing the light portion 4.
With such a hinge structure, the light portion 4 can be developed substantially in parallel to the base portion 2 and can be maintained in this state, and the light portion 4 is vertically movable with respect to the extending portion 30B. It is configured to be rotatable in the direction.

As shown in FIGS. 1, 3 and 4, the light unit 4 includes upper and lower side surfaces 41 and 42 having substantially the same size as the outer side surface 31 and the inner side surface 32 of the main body 30 </ b> A of the stand unit 3, and the main body 30 </ b> A. Left and right side surfaces 43 and 44 having substantially the same size as the left and right side surfaces 33 and 34.
As shown in FIG. 5, a wiring groove 47 that continues to the wiring groove 39 </ b> A of the extending part 30 </ b> B is provided on the lower side surface 42 of the light part 4, and the light source part 40 is wired.
A cover is attached to the wiring groove 47 in the same manner as the wiring groove 39.

As shown in FIGS. 5 and 6, the light source unit 40 is configured by housing a surface light emitter 45 in which a bare chip of a light emitting diode (LED) is directly mounted on a substrate in a shape casing of the light unit 4. As a result, the light source unit 40 is both thin and rigid, and the surface light emitter 45 connects the LED bare chip to the wiring pattern of the substrate, and a lens-like coating layer is formed on the bare chip. What is formed is used.
Such a lens-like coating layer has a lens shape as shown in FIG. 6, and light is diffused by the lens-like coating layer when the light portion is turned on.

  As described above, the lower side surface 22 of the base part 2 and the lower side surface 42 of the light part 4 have substantially the same size, and the lower side surface 42 of the light part 4 is formed on the lower side surface 22 of the base part 2. By being folded, the base 2 serves as a cover for the light source 40 of the light 4. Therefore, even during portable movement, no direct external force is applied to the light source unit 40, and damage to the substrate, wiring pattern, bare chip, or coating layer of the light source unit 40 can be prevented.

2. By arranging a notebook computer display in this irradiation space 5, it can be matched with a notebook computer, and even when the base 2 is arranged on the side of the notebook computer, it matches the notebook computer. Can be made.
3. Since the light unit 4 is configured to be able to rotate in the vertical direction with respect to the extending part 30B of the stand unit 3, it can be rotated upward to enlarge the irradiation space 5 around the desk lamp. Furthermore, the irradiation part 5 can be further expanded by rotating the stand part 3 toward the base part 2.
3. When folded Since it is folded in a substantially box shape, the volume as the desk lamp 1 can be minimized, and when it is not used as a desk lamp, the space is not taken up by minimizing the space.
5. Since the lower surface 22 of the base part 2 is a cover for the light source part 40 of the light part 4, no direct external force is applied to the light source part 40 even during mobile movement, and the light source part 40 is coated. Each component such as a layer can be protected.
6). A gap g is formed between the lower side surface 22 of the base part 2 and the light source part 40 of the light part 4, and therefore prevents the coating layer from being rubbed or cracked by the pressing force from the lower side surface 22 of the base part 2. Can do.
7). Since the base part 2 to which an electrical device such as a switch is attached is housed inside the light part 4 and the stand part 3, the electrical apparatus can be protected from an external impact.
8). The folded state is substantially box-shaped, and it is difficult to twist each part of the base part 2, the stand part 3, and the light part 4 during mobile movement, and has a structure suitable for carrying.
9. The wiring is protected by the wiring groove 39 and the cover even during the portable movement.
10. It can also be used as an emergency light during a disaster.

10. From expanded state to folded state The folding procedure for folding the base part 2 and the light part 4 sequentially toward the stand part 3 from the state of being developed in a U-shape is easy.

11. From folded to unfolded state An unfolding procedure for sequentially unfolding the light part 4 and the base part 2 from the folded state is also easy.
