[Light source member]
On the mounting substrate 1, at least one of the first light source member 41 and the second light source member 42 having different characteristics is mounted. In the light emitting device 2 shown in FIG. 2A, both the first light source member 41 and the second light source member 42 are mounted on the mounting substrate 1 (substrate 10), and the first light source member 41 and the second light source. The member 42 is electrically connected to the wiring 30.

  In the present embodiment, the first light source member 41 and the second light source member 42 emit light having different color temperatures. That is, the first light source member 41 and the second light source member 42 have different emission colors.

  For example, the first light source member 41 emits light having a relatively high color temperature with respect to the second light source member 42, and the second light source member 42 is relatively with respect to the first light source member 41. Emits light with a low color temperature. As an example, the color temperature of the first light source member 41 is 8000K, and the color temperature of the second light source member 42 is 2500K.

  The 1st light source member 41 and the 2nd light source member 42 are solid light emitting elements, such as a LED element, an organic EL element (OLED), or an inorganic EL element. In the present embodiment, LED elements (LED light sources) are used as the first light source member 41 and the second light source member 42. In this case, the 1st light source member 41 and the 2nd light source member 42 (LED element) can be comprised by wavelength conversion materials, such as a LED chip and fluorescent substance, for example.

  In this case, the light emitting device 2 (LED module) may be either an SMD structure or a COB structure. In the present embodiment, each of the first light source member 41 and the second light source member 42 is an LED element having an SMD structure. Therefore, as shown in FIG. 2B, the first light source member 41 includes a container 41a such as a white resin, an LED chip 41b mounted in the container 41a, and a sealing member 41c enclosed in the container 41a. Have. Similarly, the second light source member 42 includes a container 42a such as a white resin, an LED chip 42b mounted in the container 42a, and a sealing member 42c sealed in the container 42a.

  The LED chips 41b and 42b are bare chips that emit monochromatic visible light, for example, blue LED chips that emit blue light when energized.

  The sealing members 41c and 42c are made of a translucent material such as silicone resin. Further, the sealing members 41c and 42c may include a wavelength conversion material (phosphor or the like) that converts the light emitted from the LED chips 41b and 41b into light having a predetermined wavelength. That is, the sealing members 41c and 42c may be a phosphor-containing resin containing a phosphor. Note that a light diffusing material such as silica particles may be further dispersed in the sealing members 41c and 42c.

  For example, the phosphors included in the sealing members 41c and 42c are excited by the light emitted from the LED chips 41b and 42b to emit fluorescence and emit light of a desired color (wavelength). When blue LED chips are used as the LED chips 41b and 42b, a yellow phosphor having a fluorescent peak in the yellow wavelength region can be used.

  However, in order to make the color temperature of the light emitted from the first light source member 41 different from the color temperature of the light emitted from the second light source member 42 as in the present embodiment, the sealing member In 41c and 42c, the kind and quantity of the phosphor to be contained are changed.

  Thus, the 1st light source member 41 and the 2nd light source member 42 in this Embodiment are white LED light sources which consist of a BY type white LED element comprised by the blue LED chip and the yellow fluorescent substance. is there. In this case, the yellow phosphor absorbs a part of the blue light emitted by the blue LED chip and is excited to emit yellow light. Therefore, the yellow light and the blue light not absorbed by the yellow phosphor are mixed. White light is emitted.

  In addition, when it is set as the LED module of a COB structure as a light-emitting device, the 1st light source member 41 and the 2nd light source member 42 are the LED chip mounted in the board | substrate 10, and the sealing member which seals an LED chip. Have Also in this case, the sealing member may include a wavelength conversion material (phosphor or the like) that converts the wavelength of light emitted from the LED chip into light having a predetermined wavelength.

  In the present embodiment, the first light source member 41 and the second light source member 42 are configured to emit white light by combining a blue LED chip and a yellow phosphor. However, the present invention is not limited to this. . For example, an LED element that emits white light by using a phosphor-containing resin containing a red phosphor and a green phosphor and a blue LED chip without using a yellow phosphor may be used. Furthermore, in order to improve color rendering in the combination of a blue LED chip and a yellow phosphor, a red phosphor or a green phosphor may be further mixed in addition to the yellow phosphor.

  Moreover, in this Embodiment, although the 1st light source member 41 and the 2nd light source member 42 were white light sources, it is not restricted to this. For example, the first light source member 41 and the second light source member 42 may be LED elements having different center wavelengths (colors), for example, a red LED element, a blue LED element, or a green LED element. Also good.

The power supply terminal 22b is not electrically connected. Specifically, the first high-voltage side connection portion 33a and the second high-voltage side connection portion 33b are not connected and are not short-circuited. Further, the first low-voltage side connection portion 34a and the second low-voltage side connection portion 34b are not connected and are not short-circuited. For this reason, the 1st high voltage | pressure side connection part 33a, the 2nd high voltage | pressure side connection part 33b, the 1st low voltage | pressure side connection part 34a, and the 2nd low voltage | pressure side connection part 34b are not used as an electrical wiring. 2A is a dummy pattern.

Connected to the second power source 52. In the present embodiment, the first power supply 51 and the second power supply 52 are constant current sources. Thereby, since a predetermined direct current (constant current) is supplied to the light emitting device 2, the first light source member 41 and the second light source member 42 emit light.

  The first light source member 41 and the second light source member 42 can be driven independently by the first power source 51 and the second power source 52, respectively. Thereby, the color temperature of the light of the first light source member 41 and the second light source member 42 are adjusted by changing the light output ratio by adjusting the current amounts of the first light source member 41 and the second light source member 42. The color temperature between the light and the color temperature of the light can be varied, and desired toning can be performed. The first power source 51 and the second power source 52 are not limited to constant current sources.
