Problems solved by technology

[0007] However, when such a lamp is applied to a vehicle lamp, when a vibration load or an impact load such as a vehicle travels acts on the vehicle lamp, an unreasonable load acts on the space due to the deviation of the positional relationship between the spatial light modulator and the radiator. light modulator, whereby the spatial light modulator may break

Embodiment Construction

[0099] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0100] figure 1 It is a front elevational view showing a vehicle lamp 10 according to an embodiment of the present invention, and a partition is shown in a cross-sectional view. in addition, figure 2 Yes figure 1 II-II line cross-section, image 3 Yes figure 1 III-III line cross-section.

[0101] In these figures, the direction of x is the "front" of the lamp (also for the "front" of the vehicle), and the direction orthogonal to "front" is "orthogonal" (also for the "left side" of the vehicle. When watching the lamp is "right"), the direction is "above" when the lamp is observed. The same is true in the figure other than this.

[0102] As shown in these figures, the vehicle lamp 10 of the present embodiment is a headlight arranged at the front end portion of the vehicle, which is configured to load the projection type lamp in the lamp chamber formed by the lamp body and t...

Abstract

The present invention effectively suppresses damage to the spatial light modulator due to a vibration load or the like in a vehicle lamp including a reflective spatial light modulator. With respect to the spatial light modulator (32) supported by the supporting substrate (36), a bracket (40) abutting against the peripheral portion of the spatial light modulator is arranged on the front side of the lamp, and a bracket (40) that is in contact with the spatial light modulator is arranged on the rear side of the lamp. A heat sink (50) that elastically presses the spatial light modulator toward the front side of the lamp in a state where the central part of the device is in contact. On this basis, around the spatial light modulator, a pair of left and right shafts (56) extending in the front-back direction of the lamp are arranged in a state of being fixed to the radiator at their rear ends. Then, each shaft is inserted into each shaft insertion hole (36c) of the support substrate, and the tip of each shaft is inserted into each shaft positioning hole (40Ad) of the bracket. As a result, unreasonable loads due to deviations in the positional relationship between the spatial light modulator and the heat sink, such as vibration loads, are effectively suppressed from acting on the spatial light modulator.

Description

Technical field [0001] The present invention relates to a lamp having a reflective spatial light modulator. Background technique [0002] As a structure in which the vehicle lamp is used,, [0003] Further, since the structure of a lighting device having a reflective spatial light modulator is known, the spatial light modulator is electrically connected to the support substrate electrically connected from the rear side. [0004] Patent Document 1: Special ON 2016-91976 [0005] In the vehicle light fixture described above, the spatial distribution of the reflected light can be accurately formed by using the spatial light modulator to control the spatial distribution of the reflected light. [0006] However, as a structure of a lighting device including a reflective space light modulator, if the bracket abuts from the front side and its peripheral portion is disposed on the front side, the front side is disposed, and more relying more than the spatial light modulator The rear side...
