Abstract

PROBLEM TO BE SOLVED: To enhance stability by building a light emitting diode together with the other lighting circuit parts in the base of a desk lamp. SOLUTION: This desk lamp is provided with a head part 1 including a light source, a strut 2 for supporting the head part 1 and a base 3 with lighting parts received in and for supporting the base part of the strut 2. A node displaying part 8 for displaying the operation mode of the desk lamp is provided in the base 3, and the mode displaying part 8 is a diffusible light transmission window formed by making the specific region of a flat-plate part in the upper surface of the base 3 translucent. Further, a light emitting diode of turning on and off the light in accordance with the operation mode of the desk lamp is provided inside the base 3, and the arrangement of the light emitting diode is fixed so that the center of projection light is headed for the diagonal front thereof through the diffusible light transmission window.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a desk-type desk lamp having a mode display section on a stand base.

[0002]

2. Description of the Related Art In a conventional desk lamp,
A light emitting diode for mode display is arranged in front of the stand column supporting the head of the stand so that the operation mode can be visually recognized from the front when sitting on the desk.

[0003]

Considering the stability of the desk lamp, it is better to house the lighting components inside the stand base in terms of weight balance and assembling workability. Therefore, when a lighting component having a light emitting diode mounted on a base column is built in like a conventional stand, the center of gravity is high and the stability is impaired. There is also a method in which the light emitting diode is arranged on the stand column and the lighting component is built in the stand base and the space between them is separated. The present invention is to dispose a light emitting diode on a stand base and to alleviate the difficulty in visual recognition associated therewith.

[0004]

In the present invention, the stand base is provided with a mode display section for displaying the stand operation mode. In addition, the mode display section is a diffusive translucent window in which a specific area of the upper flat plate section of the stand base is semitransparent,
A light emitting diode that flashes according to the stand operation mode is provided inside the stand base. Further, the arrangement of the light emitting diodes is determined so that the projected light center thereof is directed obliquely forward through the diffusive translucent window.

According to the present invention, not only the light emitting diode but also the lighting component can be housed in the stand base. Therefore, the weight of the balancer (weight) attached to the stand base for stabilization can be reduced. Further, by mounting the center of the projected light of the light emitting diode toward the upper front, it becomes possible to visually recognize the blinking of the light emitting diode from a line of sight when sitting on a desk, that is, diagonally from the front.

BEST MODE FOR CARRYING OUT THE INVENTION The embodiment of FIGS. 1 and 2 according to the present invention will be described. A stand head 1 including a fluorescent lamp (not shown), a stand column 2 for movably supporting the same, and a stand base 3 for erecting the stand column 2.
Is provided. The stand base 3 includes a light emitting diode 4 for displaying an operation mode, a lighting circuit board 5,
The balancer 6 is provided to ensure stability. Generally, the light output of the light emitting diode 4 is small. For this reason, directivity is given so that the projection light in a required direction is strengthened. In the present invention, as shown in FIG. 2, the legs are bent so that the center of the projected light of the light emitting diode 4 (longitudinal direction of the light emitting diode 4) is directed obliquely forward and mounted on the lighting circuit board 5, It is placed in the base 7. This improves the visibility from the diagonally front side. 7 is stand base 3
Is the top cover. When a desk lamp was prototyped and confirmed, the bending angle of the light emitting diode 4 was 3 with respect to the desk top surface.
The range of 5 ° to 50 ° is particularly effective for improving visibility. The surface of the stand base 3 is provided with a diffusive translucent window 8 in which the surface of a transparent resin plate is matt (matted) in order to diffuse the projection light of the light emitting diode 4. This diffusive translucent window 8 prevents dust and dirt from entering the base. The diffusive translucent window 8 acts to weaken the light of the light emitting diode 4,
When viewed along the projected light center of the light emitting diode 4, high visibility is exhibited. If it deviates significantly from that point, the visibility will drop extremely.

[0007]

According to the present invention, since the light emitting diode can be built in the stand base together with other lighting circuit parts,
Stability is improved. It uses a light emitting diode with a small light output and a diffusive translucent window is also attached, but it is highly visible from the necessary direction and is easy to use.
