The socket 2b has a plate-shaped contact 2e exposed from the inside of the socket part 2d to the outside of the slide groove engaging part 2C. It is optional to interpose a current limiting resistor as necessary. It is preferable that the contact portions disposed on the inner and outer sides bulge outward so as to easily maintain contact with the light emitting body 2a and the main line 3d, respectively.

The support member 3 is made of a heat-resistant synthetic resin such as polycarbonate that has appropriate hardness and flexibility to maintain its shape, and has a generally U-shaped cross section that accommodates the light emitting unit 2 therein. An opening 3a which is a long body and allows the light emitting unit 2 to be slid in the longitudinal direction, and a slide groove that sandwiches the slide groove engaging portion 2C of the light emitting unit 2 formed on the inner side surface of the opening. 3b, 3b, an inner bottom surface 3C, and a main line 3d made of a conductor such as a copper wire, which is buried in the inner surface part so as to be partially exposed and protrudes inward and can be contacted with the contactor 2e of the light emitting unit 2. 3d, small holes 3e for fixing screws are formed at appropriate locations at both ends and the middle of the inner bottom surface 3C, and an engagement step for locking the translucent cover 4 is formed at the lower end of the outer surface. aB3f is formed.

The translucent cover 4 is made of a synthetic resin such as polycarbonate, which has appropriate hardness and flexibility to maintain its shape, heat resistance, and translucency, and is made of a synthetic resin such as polycarbonate. It is a long body with a cross-sectional shape that fits into the body, and has both ends 14a.
, 4a is formed with a locking protrusion 4b that can be engaged with the engagement step 3f of the support member 3.

The variable light source illumination tube 1 having the above configuration can be installed by attaching a plurality of light emitter units 2 to the support member 3 by engaging them with the slide grooves 3b, or by attaching the light emitter units 2 in advance and then attaching them to the support member 3. Slide the light-emitting unit 2 and place it at a desired position on the support member 3, simultaneously place the required number of light-emitting units 2 on the support member 3, and then touch the support member 3 to an installation part such as a wall surface. , screw the screw 5 through the small hole 3e and secure it. At this time, if the light emitting unit 2 overlaps the small hole 3e, it is sufficient to first shift the light emitting unit 2, attach the screw 5, and then return the light emitting unit 2 to its original position. It is possible to change the position and number of the light emitters 2e.

Of course, the above procedure may be reversed. Further, the light-transmitting cover 4 is attached by pressing the light-transmitting cover 4 from the front surface of each support member 3, causing the engagement protrusion 4b to engage with the engagement step portion 3r.

In addition, when the variable light source illumination tube l of the present invention is installed in series,
In the same manner as described above, the light emitting unit 2 is arranged on the support member 3, and an appropriate joint is interposed between the adjacent support members 3.3 so that the main lines 3d and 3d can be electrically connected. The support member 3 is installed in a straight line or, if desired, bent within the bending range of the support member 3. d, 3
An end socket provided with a connection line to which a voltage can be applied may be attached to d, and the connection line may be connected to a power source. Of course, the above installation procedure may be changed as desired.

The variable light source illumination tube 1 of the present invention includes an end socket from a power source,
Each support member 3 via the main lines 3d, 3d and joints
When a voltage is applied to the main lines 3d, 3d, current is supplied to the light emitter 2a through the contacts 2e, 2e in contact with the main lines 3d, 3d, and the light emitter 2a lights up. It is possible to easily arrange and light up the light emitting body, and it is possible to arbitrarily and diversely create a lighting mounting part with a desired arrangement of light emitters.

Moreover, the brightness can also be changed.

In addition, in the above embodiment, along the longitudinal direction of the support member 3,
Although the pair of main lines 3d and 3d are attached, the present invention is not limited to this, and the attachment position and shape of the main lines 3d and 3d can be adjusted as long as the contact with the light emitting unit 2 is maintained. Although it can be formed in any position and shape, the third
It is preferable that it is not visible from the front side as shown in FIGS. In addition, the number of main lines is 3 to 4 or more, and the number, shape, and arrangement of the contacts 2e of the light emitting unit 2 are changed accordingly, and the voltage application time to each main line is changed accordingly. By controlling the flow blinking pattern can be obtained. In addition, if the light emitter 2a is a light emitting element with polarity such as an LED, a blinking pattern can be created with just a pair of trunk lines, and marks for positioning the light emitter unit 2 are printed at appropriate locations on the surface of the support member 30. It can be formed by engraving or other appropriate means. Furthermore, if small irregularities that engage with each other are formed at regular intervals on the contact surface between the light emitting unit 2 and the support member 3, for example, at a pitch of several squares, it can serve both as a mark and to strengthen the fixing force. .

In addition to the above configuration, configurations that further enhance the decorative effect of the light emitters are possible, and some examples will be described below.

A reflective layer can be formed on the supporting member 3 by appropriate means, such as attaching a reflective member such as a so-called mirror tape, to a portion of the inner bottom surface 3c that is visible from at least the front side. Thereby, a synergistic decorative function is exhibited by the direct light from the light emitter 2 and the reflected light from the reflective layer.

Further, the translucent cover 4 may be colored as long as it has translucency, and colored illumination can thereby be provided.

Furthermore, by attaching a semi-transparent mirror film or the like to the inner surface of the translucent cover 4 and attaching a reflective member such as mirror tape to the inner bottom surface 3c of the support member 3, countless light sources can be generated inside the variable light source illumination tube 1. It is possible to create a decorative feeling that exists both far and near.

Furthermore, various display materials such as SpectraScoo (manufactured by Spectratic, Inc., USA), which can create a red pattern by the diffraction effect of light, can be attached to the inner surface of the translucent cover 4. You can get a dramatic effect.

In addition to the above, various decorations are possible, and these two
By combining the above, even more decorativeness can be added.

In the above embodiment, both the support member 3 and the translucent cover 4 have a U-shaped cross section, but the present invention is not limited to this, and the light emitting body may be placed at any position or the position may be changed. As long as the light-emitting body and the main line can be protected from the outside, the translucent cover 4 shaped like a semi-circular arc can be used as a supporting member 3 having a substantially C-shaped cross-section as shown in FIG. The support member that is attached to the installation part such as the wall surface in advance can be attached to the engagement member for use, or the approximately C-shaped support member can be attached to a flexible support member as shown in Fig. 4. It may be arranged in a tube-shaped light-transmitting cover 4 so that it can be bent as desired.Furthermore, as shown in FIG. It is also possible to make a modification such as forming slide grooves on both edges and sliding the flat transparent cover 4 from the longitudinal direction. In addition to screws, the support member 3 may be fixed to the installation part by double-sided adhesive tape 6 as shown in FIG. The support member 3 can be fixed by appropriate means such as locking the support member 3 to this hook or the like. It goes without saying that the arrangement of the main lines and the shape of the light emitters can be changed as appropriate in accordance with each of the above-mentioned modifications.

(Effects of the Invention) As described above, according to the variable light source illumination tube of the present invention, the number and position of the light emitters can be easily changed. In addition to significantly reducing distribution inventory, specifications can also be easily changed at the construction site.

Moreover, since the present invention allows the light emitting body to be placed at any position on the support member, the brightness can be changed continuously or intermittently even in a single lighting tube, and when the light emitting body is installed in series, the brightness can be changed continuously or intermittently. Furthermore, the layer decoration effect can be enhanced.
