Each phosphor absorbs a portion of the light emitted from the corresponding LED element 80 and emits light having a wavelength different from the light emitted from the LED element 80.

    For example, the LED element 80 emits light having a dominant wavelength in a wavelength range of 420 to 490 nm. The first wavelength converting element 91 converts a portion of the light emitted from the LED element 80 into light having a dominant wavelength in a wavelength range of 560 to 570 nm and allows at least a portion other than the portion of the light emitted from the LED element 80 to be transmitted therethrough.

    The third wavelength converting element 93 converts a portion of the light emitted from the LED element 80 into light having a dominant wavelength in a wavelength range of 575 to 585 nm and allows at least a portion other than the portion of the light emitted from the LED element 80 to be transmitted therethrough.

    [0034]
    Fig. 4 is a block diagram showing a vehicle fire system 100 comprising the vehicle light 10 shown in Fig. 1.
    The vehicle fire system 100 includes the vehicle light 10 and a vehicle control device 66.
    [0035]
    The vehicle control device 66 controls the vehicle light 10 in an integrated manner. The vehicle control device 66 transmits, to the vehicle light 10, an ignition / extinguishing command S1 for switching on / off the light and information (displacement information) S2 indicating a displacement condition, and similar. The SI switching on / off control includes adjustment control from a user for the light flow (hereinafter, the light flow of the light radiated from the fire unit is simply called "Light flow of the fire unit") from the light radiated from each fire unit, in addition to the ignition / extinguishing instruction for each fire unit from the user. The displacement information S2 comprises a vehicle speed.
    [0036]
    The vehicle light 10 further comprises a fire control device 72 and three drive circuits 76. The fire control device 72 separately controls the first fire unit 18, the second fire unit 20 and the third fire unit. 22 on the basis of the SI switching on / off command and the S2 traveling information from the vehicle controller 66. Specifically, the fire control device 72 generates a gradation signal S3 on the base of the SI switch-on / switch-off command and the S2 shift information. Each of the drive circuits 76 provides an ILed drive current as a function of the dimming signal S3 to the LED element 80.
    [0037]
    During high speed movement, the fire control device 72 is controlled so that a fire unit, in which the degree of condensation of the light is high and the color temperature proximal to the radiated light is relatively high, is on. Specifically, the fire control device 72 controls the first fire unit 18 so that the light flow of the first fire unit 18 to form the condensed light distribution pattern
    Pa is increased (i.e., the brightness of the LED element 80 of the first light source is increased) when the vehicle speed indicated by the displacement information S2 is equal to or greater than a first speed (for example, 60 km / h). Further, in addition to the first fire unit 18, the fire control device 72 can control the second fire unit 20 so that the light flow from the second fire unit 20 to form the light distribution pattern average diffusion Pb is increased (that is, the brightness of the LED element 80 of the second light source is increased). In this case, the fire control device 72 can control the third fire unit 22 so that the light flow of the third fire unit 22 to form the high-scatter light distribution pattern Pc is decreased (c that is, the brightness of the LED element 80 of the third light source is decreased).
    [0038]
    Further, during moving at a medium speed, the fire control device 72 is controlled so that a fire unit, in which the degree of light condensation (i.e., the degree of diffusion ) is almost moderate and the proximal color temperature of the radiated light is almost moderate, ie it is on. Specifically, the fire control device 72 controls the second fire unit 20 so that the light flux of the second fire unit 20 to form the average scattering light distribution pattern Pb is increased (ie that is, the brightness of the LED element 80 of the second light source is increased) when the vehicle speed indicated by the displacement information S2 is smaller than the first speed but equal to or greater than a second speed (for example example, 40 km / h). In this case, the fire control device 72 can control the first fire unit 18 and the third fire unit 22 so that the light flow of the first fire unit 18 to form the condensed light distribution pattern Pa and the light flux of the third fire unit 22 to form the high scatter light distribution pattern Pc is decreased.
    [0039]
    In addition, during a low speed movement, the fire control device 72 is controlled so that a unit of fire, in which the degree of light condensation is low (i.e. diffusion rate) and the proximal color temperature of the radiated light is relatively low, is on. Specifically, the fire control device 72 controls the third fire unit 22 so that the light flow of the third fire unit 22 to form the high scatter light distribution pattern Pc is increased when the indicated vehicle speed by the displacement information S2 is less than the second speed, but equal to or greater than a third speed (for example, 0 km / h, that is to say, the stopped state). Further, in addition to the third fire unit 22, the fire control device 72 can control the second fire unit 20 so that the light flow of the second fire unit 20 to form the light distribution pattern average diffusion Pb is increased. In this case, the fire control device 72 can control the first fire unit 18 so that the light flow of the first fire unit 18 to form the condensed light distribution pattern Pa is decreased.
    [0040]
    Further, the fire control device 72 controls the first fire unit 18, the second fire unit 20 and the third fire unit 22 on the basis of the adjustment instruction from a user for the flow of fire. light of each fire unit, which is included in the SI ignition / extinguishing control. For example, when the SI switching on / off control comprises an instruction to turn on the fire unit with a high degree of light condensation, the fire control device 72 controls the first fire unit 18 so that the light flux of the first fire unit 18 to form the condensed light distribution pattern Pa is increased. Further, for example, when the SI switch-on / switch-off control includes an instruction to turn on the fire unit with a medium degree of diffusion, the fire control device 72 controls the second fire unit 20 so that that the light flux of the second fire unit 20 to form the average scattering light distribution pattern Pb is increased. Further, for example, when the SI switch-on / switch-off control comprises an instruction to turn on the fire unit with a high degree of diffusion, the fire control device 72 controls the third fire unit 22 so that that the light flux of the third fire unit 22 to form the high diffusion light distribution pattern Pc is increased.
    [0041]
    In accordance with the vehicle fire system 100 of the present embodiment described above, the fire units are configured such that the higher the degree of condensation of the radiated light (conversely, the lower the degree of diffusion is) , the higher the color temperature proximal to the radiated light. In addition, the light flux of each fire unit is controlled to be varied according to the vehicle speed. In particular, when the vehicle speed is high, the light flow of the fire unit, in which the degree of light condensation is high and the proximal color temperature of the radiated light is relatively high, is controlled for increase. In other words, when the vehicle speed is high, the light flow of the fire unit, which illuminates a so-called hot area and in which the proximal color temperature is relatively high, is controlled to increase. In addition, when the vehicle speed is almost moderate, the light flow of the fire unit, in which the degree of condensation of light is almost moderate and the proximal color temperature of the light radiated is almost moderate, is ordered to increase. In addition, when the vehicle speed is low, the light flow of the fire unit, in which the degree of light condensation is low (i.e. the degree of diffusion is high) and the proximal color temperature of the radiated light is relatively low, is controlled to increase. In this way, it is possible to improve the visibility for the remote area during a high speed movement. In addition, it is possible to improve the visibility for the relatively remote area while reducing or eliminating glare for pedestrians or oncoming vehicles during a medium speed trip. In addition, it is possible to improve the visibility for the area relatively close to a particular vehicle while reducing or eliminating glare for pedestrians or oncoming vehicles during low speed travel (ie to say, during a city trip). That is, according to the vehicle fire system 100 of the present embodiment, it is possible to improve the visibility for a driver.

    In the present modification, each light source comprises a different LED element from the others, as described above. That is, each light source comprises an LED element that emits light having a dominant wavelength in a different wavelength range.
    [0046]
    In addition, each of the light sources comprises the wavelength conversion element 190. That is, the respective light sources comprise the wavelength conversion elements in which the composition and Phosphorus concentration and thickness are substantially the same. The phosphor included in the wavelength converting element 190 absorbs a portion of the light emitted from the first LED element 181, the second LED element 182 or the third LED element 183 and emits light having a light length. different wave from that of the light emitted from these LED elements.
    [0047]
    The first light source 151 radiates a light having the proximal color temperature Tel, wherein the light emitted from the first LED element 181 and transmitted through the wavelength converting element 190 and the light converted to length by the wavelength converting element 190 are mixed. The second light source 152 radiates light having the proximal color temperature Tc2, wherein the light emitted from the second LED element 182 and transmitted through the wavelength converting element 190 and the light converted to length by the wavelength converting element 190 are mixed.

    [0049]
    According to this modification, the same effects as those of the vehicle lamp 10 according to the embodiment can be obtained.
    [Second modified]
    Figs. 6A-6C are schematic sectional views of a light source included in each light unit of a vehicle light according to another modification of the embodiment. Fig. 6A shows a first light source 251 included in the first light unit 18, Fig. 6B shows a second light source 152 included in the second light unit 20, and Fig. 6C shows a third light source 153 included. in the third fire unit 22.
    [0051]
    The first light source 251 includes a first LED element 281, a fourth LED element 284, and the wavelength conversion element 190. That is, the first light source 251 comprises two types of light sources. LED elements. The wavelength converting element 190 is disposed on an optical path of the first LED element 281 and the fourth LED element 284. In the present embodiment, the wavelength conversion element 190 is disposed of. in order to cope with a light emitting surface 281a of the first LED element 281 and a light emitting surface 284a of the fourth LED element 284.
    [0052]
    Part of the light emitted from the first LED element 281 is converted into wavelength by the wavelength conversion element 190 and at least a portion other than the portion of the light emitted from the first element LED 281 is transmitted through the wavelength conversion element 190. On the other hand, the light emitted from the fourth LED element 284 is substantially transmitted through the wavelength conversion element 190. For example, 50% or more of the light emitted from the fourth LED element 284 can be transmitted through the wavelength conversion element 190.
    [0053]
    White light having the proximal color temperature Tel is generated on the basis of wavelength converted light by the wavelength converting element 190, light emitted from the first LED element 281 and transmitted through the wavelength conversion element 190, and the light emitted from the fourth LED element 284 and substantially transmitted through the wavelength conversion element 190.

In addition, the wavelength conversion element 190 allows the brown to red light emitted from the fourth LED element 284 to be substantially transmitted therethrough. For example, the wavelength conversion element 190 may allow 50% or more of the brown to red light emitted from the fourth LED element 284 to be transmitted therethrough.
    [0056]
    In this modification, the wavelength conversion element 190 comprises a phosphor.

At least a portion other than the portion of the light emitted from the first LED element 281 is emitted from the wavelength conversion element 190 without being absorbed by the phosphor. Further, the brown light emitted from the fourth LED element 284 is emitted from the wavelength conversion element 190 without being substantially absorbed by the phosphor (for example, while 50% or more of the light brown is not absorbed by phosphorus). In particular, brown to red light emitted from the fourth LED element 284 is scattered in the wavelength conversion element 190 and outputted from the wavelength conversion element 190.
    [0057]
    The blue light transmitted through the wavelength conversion element 190 and the light converted to yellow light by the wavelength conversion element 190 is mixed, thereby generating a white light. In the present embodiment, the brown light transmitted through the wavelength conversion element 190 is further mixed with the white light. By modifying the light flux of the brown light mixed with the white light, it is possible to modify the proximal color temperature Tel of the white light.
