Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device, and more particularly, to a lighting device having direct light and indirect light by the same type of light source in the same fixture.

[0002]

2. Description of the Related Art Conventionally, as an illuminating device having direct light and indirect light by plural kinds of light sources (different kinds of light sources) in the same fixture, there is an illuminating device having different kinds of light sources such as a fluorescent lamp and an incandescent lamp. Among such illuminating devices, since the light control characteristics of the respective light sources are different, there is a device that changes the light control curve (data) for each light source when controlling the light control of each light source. (For example, JP-A-5-315083, JP-A-7-6877, and JP-A-7-6596.

However, in the illuminating device having direct light and indirect light by different light sources in the same fixture, the following problems occur.

In this type of illuminating device, for example, when two or more light sources in the same fixture have different W, even if they have the same dimming control curve, the appearances thereof are different. . On the other hand, even when the light sources in the same device have the same W, if the light sources constitute direct light and indirect light, the dimming characteristics are the same, but the indirect light is more human than the direct light. In, it is difficult to understand the change in brightness, and it is particularly difficult to understand the change in brightness when the dimming ratio is near 0% or near 100%. Therefore, it becomes difficult to obtain the effect of indirect light.

The present invention has been made in view of the above problems, and an object of the present invention is to have direct light and indirect light by the same type of light source in the same device, and to provide a unique feature of direct light and indirect light. An object of the present invention is to provide an illuminating device that can obtain a remarkable effect.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a block diagram of an embodiment according to the present invention.

As shown in FIG. 1, the illuminating device 1 according to the present invention includes light sources 3A and 3B of the same kind which are capable of dimming control, and a light source 3.
Lighting circuit 2 for controlling blinking and dimming of A and 3B respectively
A and 2B, and light control data 5A of the light sources 3A and 3B,
5B and the control circuit 6 including the dimming signal circuits 4A and 4B for outputting the dimming signal for controlling the lighting circuits 2A and 2B based on the dimming data 5A and 5B are arranged in the same fixture. It is a thing.

As described above, since the dimming data is individually provided for each light source, even the lighting device having the same type of light source can obtain different effects for each light source during dimming control. If the number of light sources is three or more, the dimming signal circuit 4 and dimming data 5 may be increased by the number of light sources. Furthermore, in an illuminating device having the same type of light source in the same fixture, by using at least one light source of a plurality of light sources as direct light for obtaining illuminance and other light sources as indirect light for changing the atmosphere, The unique effects of light and indirect light can be remarkably obtained.

Specific examples of the dimming data 5 when two light sources are used are shown in the first to third embodiments below.

From the characteristic curve shown in FIG. 2, when the light output is low, the change rate of the light output of the light source 3A is larger than the change rate of the light output of the light source 3B. Greatly gained. On the other hand, when the light output is high, the change rate of the light output of the light source 3B is larger than the change rate of the light output of the light source 3A, so that the effect of changing the illuminance (brightness) by the light source 3B is greatly obtained.

Therefore, when the light source 3A is the indirect light and the light source 3B is the direct light, the respective unique effects of the direct light and the indirect light can be remarkably obtained.

The difference from the characteristic diagram of the dimming data 5 shown in the first embodiment (FIG. 2) is that the characteristic curves of the light source 3A and the light source 3B have the same direction characteristics but different inclinations. The same configurations as those of the other first embodiment are designated by the same reference numerals and the description thereof will be omitted.

(Embodiment 3) FIG. 4 shows a characteristic diagram of the dimming data 5 in the third embodiment according to the present invention.

The difference from the characteristic diagram of the dimming data 5 shown in the first embodiment (FIG. 2) is that the characteristic curves of the light source 3A and the light source 3B are partially different, and the other portions are the same. Since the same configurations as those of the other first embodiment are designated by the same reference numerals, the description thereof will be omitted.

The characteristic curves of the light sources 3A and 3B are not limited to those shown in the first to third embodiments, and
Any material can be used as long as it can remarkably obtain the unique effects of direct light and indirect light. In addition, the above first to first
