In the present invention configured as described above, a hole (hole 4-1) is formed in the cover base 4-2 of the bulb cover 4 as shown in FIG. The epoxy resin is melted and filled with the coupling means C in the space between the light emitting lamp 30 and the hole 4-1 so that the light emitting lamp 30 connected to the wires is connected to the hole 4-1. In this case, as shown in FIG. 6, the unit diffusion light-emitting body 100 in which the holes 4-1 are formed by the coupling means C can be easily assembled. This is because they are combined as shown in FIGS. 11 to 13. In addition, the control circuit for driving the light emitting lamp 30 functions as shown in FIG.

That is, the light emitting lamp 30 has one control circuit (for example, a known control circuit which sequentially emits light using a shift register, installs a plurality of colors of the light emitting lamps 30, or installs a plurality of light emitting lamps, or enables a flashing operation). A general control technique is used to control the power supply, and the operation of the control unit 130 allows the power of the battery or the adapter 135 to be applied by the switch 131, and the applied power is the light emitting lamp through the wire 133. 30 is intermittently or continuously operated, and each lamp 30 incorporates a drive program in the controller 130 to drive individually or simultaneously or selectively.

Is generated in the front and side (side lobe), light is transmitted at the incident angle (∂10) and the refraction angle (∂20) based on the normal to each point of the convex surface forming the surface of the clad layer 12 Therefore, the surface of the convex portion 10 functions to achieve uniform illumination. This is because in the core layer 11, the light of the light emitting lamp 30, which is a light source, goes straight, but the cladding layer 12 forms a curved surface, so that the incident angle ∂10 (∂10 ') at most normal points is a critical angle ( Since light is transmitted through the refractive angle ∂20 (∂20 ') at each normal point of the convex surface without exceeding ∂c), uniform illumination is achieved on the surface of the convex portion (through the unit light emitting lamp 30). It is not a concept of simple surface emission in which light simply goes straight, but acts as a diffusion light emitting body that uniformly illuminates the convex portion 10 having a diameter larger than that of the light emitting lamp 30). Of course, each incidence angle ∂10 (∂10 ') forms a reflection angle ∂30 (∂30') and reflects the light into the core layer 11 to transmit light at some point, thereby improving illuminance. do. In this case, the cladding layer 12 is a medium (for example, an air layer) having different refractive indices provided with uniform linearity of light through the thermoplastic (curable) synthetic resin polymer forming the core layer 11.

In addition, adding a translucent translucent layer to the surface of the cladding layer 12 may provide a soft brightness, or may be configured to transmit light in a translucent state by adding fine mineral particles such as fat sugar in the core layer 11. have.

The present invention acting as described above is equally applicable to the third and fourth examples in which the reflective layer 40 is disposed on the back surface of the light emitting lamp 30 of FIGS. 5 and 6 showing the first and second examples. Although the reflective layer 40 functions to make the light of the auxiliary light emitter 140 visible from the outside, it also functions as an auxiliary reflector to give a directivity of the bulb 3 to provide an entirely new aesthetic effect. That is, based on the light bulb cover, the lower part provides light of the bulb 3 and the upper part provides light of the auxiliary light emitter 140 to provide a completely new lighting effect.

In the above, an example in which the hole 4-1 is formed in the bulb cover 4 and illuminated is described. However, as shown in FIGS. 9 and 10, the method of overlaying the existing bulb cover 4 as shown in FIGS. 9 (5) and FIG. It can also be used as 10 (6 examples). This is formed by forming a hole 111 in advance in the base 110 of a predetermined length as shown in FIG. 14, and fitting into the light emitting fixing groove 15 of the unit diffusion light emitting body 100 in the hole 111. It can be manufactured in the form of color and size, it is easy to implement a variety of designs, and if it is fixed in a closed loop form using the fixing means (134,136), a plurality of diffused light emitting body 100 'is easily manufactured, as shown in FIG. It is easy to use because it can be fixed in the form.

In addition, if connected using the connector 120 instead of the base 110 of FIG. 14 as shown in FIG. 15 (seventh example), it is also possible to design a variety of shapes in the desired shape more easily to the bulb cover (4) or reflector (5) Function to be used in combination.

In the above, the installation in the bulb cover 4 has been described mainly, but the present invention is not limited thereto and may be used in combination with FIGS. 14 and 15.

As described above, the present invention makes holes in the light bulb cover that forms a general street light and combines the light emitting lamp as a coupling means to emit light in a different color and shape than the conventional light bulb, so that various decorations can be implemented. If the bulb is turned off and only the auxiliary light is turned on, it functions as a luminous lamp on the road like a luminous lamp in a house, thus contributing to the prevention of safety accidents and providing a decorative effect.

In addition, the present invention drills a hole in the bulb cover and combines the light emitting lamp as a coupling means, and if the coupling means is implemented as a unit diffuse light emitting body, it emits light in a color and shape different from the conventional street light bulbs can implement a variety of decorations Since the light is diffused and lit, a single lamp emits light by covering a large area, which reduces power consumption.If the light is turned off at night and only the auxiliary light is turned on, it functions as a luminous lamp on the road like a luminous lamp in a house. It also contributes to the prevention of safety accidents and provides a decorative effect.

In addition, the auxiliary light emitting unit is formed to form a multi-diffusion light emitting unit in which the unit diffusion light emitting unit is again combined with the base on the band, and is combined to form a closed loop by using a fixing means at both ends thereof so as to enclose the bulb cover to facilitate installation. Enhances the decorative effect in various forms.

In addition, the present invention can implement the auxiliary light emitting function through the auxiliary light emitting body, unlike the conventional street light, so it is not necessary to decorate the road separately in tourist attractions, etc., and if the light emitting lamp is used as a low power consumption lamp such as an LED lamp, The cost of use can also be extremely low, so the maintenance cost paid for the decorative effect is extremely low and economical.
