An image acquiring apparatus for a vehicle includes a light emitting unit configured to emit pulse light to a predetermined direction, an image acquisition unit configured to acquire a plurality of different images of target distance ranges by imaging reflected light returning from the target distance ranges at imaging timings set according to the target distance ranges, and a timing controller configured to control a light emission cycle of the pulse light and the imaging timings. The timing controller is configured to set a light emission interval time to be longer than a delay time which is a time from a light emission start time point of the light emitting unit to an imaging start time point of the image acquisition unit and is required to image a longest-distance range of the target distance ranges from which the reflected light can be imaged.

In a light emitting module, light wavelength conversion ceramicconverts the wavelength of the light emitted by a semiconductor light emitting element. The light wavelength conversion ceramicis made so transparent that the light wavelength conversion ceramichaspercent or more of the total light transmittance of the light with a wavelength within the conversion wavelength range. A reflective filmis provided on the surface of the light wavelength conversion ceramicand narrows down the emission area of the light that has transmitted the light wavelength conversion ceramicto an area smaller than the light emitting area of the semiconductor light emitting element. In the case, the reflective filmguides the light such that the light is emitted in the direction approximately parallel to the light emitting surface of the light emitting element

Light emitting module, method of manufacturing the light emitting module, and lamp unit

A light emitting device module is provided. The light emitting device module includes a plurality of light emitting devices; a submount on which the light emitting devices are mounted; and a heat-radiant substrate to which the submount is fixed. The submount includes a positive front surface electrode; a negative front surface electrode; at least one relay front surface electrode, wherein the plurality of light emitting devices are electrically coupled to each other in series via the at least one relay front surface electrode; a plurality of through electrodes; a positive back surface electrode coupled to the positive front surface electrode via a through electrode; a negative back surface electrode coupled to the negative front surface electrode via a through electrode; and at least one relay back surface electrode which is coupled to the at least one relay front surface electrode via a through electrode. The heat-radiant substrate includes a positive circuit electrode bonded to the positive back surface electrode; a negative circuit electrode bonded to the negative back surface electrode; and at least one relay circuit electrode bonded to the at least one relay back surface electrode and being floated electrically.
