  • Patent number: 12320493
    Abstract: A flexible warning light includes a lamp housing including a base with a bottom plate, a flexible lamp shell covering base and an accommodation space defined between base and flexible lamp shell, and a light-emitting device mounted in the accommodation space and having at least one light-emitting element on the top of a flexible circuit board of a light-emitting device on the top, and a first heat sink and multiple second heat sinks on the bottom. The flexible lamp shell will elastically deform in accordance with the surface curvature of a preset vehicle body to drive first heat sink and second heat sinks to deform so that the base can be closely attached to the curved surface of the preset vehicle body through the deformation of the first heat sink and the second heat sinks, so as to achieve the effect of being more compliant with the curved vehicle body.

  • Patent number: 11549667
    Abstract: A lighting device includes a housing, a light emitting module, a press plate and a fixing member. The housing has a bottom plate, a base and multiple stopping portions. The base protrudes from the bottom plate, and has a top surface and an inclined surface. The stopping portions are arranged at the bottom plate and extend to a bottom portion of the inclined surface of the base. The light emitting module includes a light panel and multiple light emitting elements arranged thereon. The light panel leans on the inclined surface and stopped by the stopping portions. The press plate is located at the top surface, and presses against the light panel. The fixing member fixes the press plate at the top surface to cause the press plate to press the light panel downward, so as to fix the light panel on the inclined surface.
