As shown in FIGS. 1 and 2, the lamp according to the first embodiment of the present invention can emit light to illuminate, and can also adjust toning, dimming, and adjusting the color temperature of the emitted light. Specifically, the lamp has a base portion 10, a light source portion 20, and a translucent glove 30. The light source unit 20 has a support stem 21 and a strip light 22. By assembling, the translucent glove 30 and the base portion 10 are connected to form a storage space, the light source unit 20 is attached to the storage space and electrically connected to the base portion 10, and the base portion 10 is used as electricity for the house. By connecting to a circuit, power is supplied and the light source unit 20 is controlled to emit light. The support stem 21 is fixed to the base portion 10 as a support member for assembling the strip light 22. Then, the strip light 22 is spirally installed so as to wind around the support stem 21, so that the strip light 22 can emit light over the entire circumference in the storage space, and can emit light in a wider range. .. In the lamp, the strip light 22 is composed of a plurality of light emitting filaments arranged in parallel. As shown in FIG. 5, each light emitting filament emits light of a different color, and each of the light emitting filaments is electrically connected to the base portion 10, and a plurality of light emitting filaments are formed by power supply and control via the base portion 10. Each emits light independently, or a plurality of light emitting filaments are arbitrarily combined to emit light. When each light emitting filament emits light independently, a single color emission illumination can be realized, and when a plurality of light emitting filaments emit light in any combination, dimming and toning functions can be realized, and different combinations emit light. By doing so, it is possible to adjust the color temperature of the emitted light, and therefore, it is possible to diversify the emitted light of the lamp and meet the lighting work requirements of different scenes.

When illuminating by emitting light using a lamp equipped with lighting, dimming, and toning functions according to the present invention, a plurality of light emitting filaments that emit light of different colors are controlled by the base 10 respectively. By emitting light independently or in combination arbitrarily, multicolored emission light illumination, dimming, and toning-capable emission light illumination can be realized, and the lighting work requirements of different scenes can be satisfied.

In Example 1, each light emitting filament is wrapped by a fluorescent layer (not shown), and thus a plurality of light emitting filaments are covered by the fluorescent layer and form a strip light 22 in parallel.

It is possible to realize dimming by the method and toned emission light illumination. Specifically, the emission light illumination of yellow light can be realized by lighting the red light filament 221 and the green light filament 222 at the same time, and the cyan light is emitted by lighting the green light filament 222 and the blue light filament 223 at the same time. Illuminated illumination can be realized, and by lighting the red light filament 221 and the blue light filament 223 at the same time, the emission light illumination of magenta color light can be realized, and the red light filament 221, the green light filament 222, and the blue light filament 223 are turned on at the same time. By doing so, it is possible to realize the emission light illumination of white light, and by simultaneously lighting the red light filament 221 and the green light filament 222 and the blue light filament 223 together with the white light filament 224, the emission light illumination effect of brighter white light is achieved.
