The present invention relates to a warning light device, and more particularly to a blind spot warning device for a backview mirror.
Typically, the backview mirror is installed on both sides of the vehicle, so that the driver can observe the situation behind the both sides of the vehicle through the backview mirror. It can also be used to determine whether there are coming vehicles on both sides of the vehicle, so as to be alert before changing lanes and make early preparations. However, even with the backview mirror, there are still blind spot areas that cannot be fully observed from the rear side of the vehicle. Therefore, many car manufacturers have introduced the technology of the backview mirror with blind spot warning lighting for vehicles as standard.
The blind spot warning light device is usually installed in the casing of the backview mirror of the vehicle, and is connected to the sensors on both sides of the vehicle. When the rear vehicle enters the blind spot area, the blind spot warning light device can be activated by the sensors, so that the illuminated LED source can be emitted from the translucent region of the mirror, to achieve the effect of reminding the driver to pay attention.
However, the conventional structure described above still has the following issues in practical applications: LED lights are point light sources emitted in a straight line, when used in a night environment, it can be extremely dazzling, which can cause glaze and hazard to the driver.
Therefore, it is desirable to provide a warning light device for a backview mirror to mitigate and/or obviate the aforementioned problems.
An objective of present invention is to provide a warning light device for a backview mirror, which is capable of improving the above-mention problems.
In order to achieve the above mentioned objective, a warning light device for a backview mirror has a backview mirror and a warning unit. The backview mirror has a casing and a mirror corresponding to each other. The mirror has a translucent region allowing the warning unit disposed in the casing to be aligned with the translucent region on the mirror. The warning unit has a lighting device, an illumination cover and a circuit board. The lighting device has a containment space and an opening connected to the containment space, the circuit board disposed in the containment space through the opening. The lighting device further has a through aperture on one side for accepting wires of the circuit board; the circuit board further comprising a plurality of illuminating members behind the opening. The illumination cover has a translucent plate configured to cover the opening. A plurality of illumination rods are disposed in the containment space and in front of the translucent plate facing the illuminating members, and the illumination rods is cone-shaped, secured onto the mirror via the lighting device, and keeps the translucent plate facing the translucent region.
Other objects, advantages, and novel features of invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
First, please refer to
Moreover, a supporting foot 223 respectively extends from four corners of the translucent plate 221 and is configured to lift the illumination cover 22 in the lighting device 21.
In addition, the circuit board 23 further has four illuminating members 232.
Furthermore, the circuit board 23 further has two red illuminating members 232 and two orange illuminating members 232. When the sensors sense the vehicle approaching, the orange illuminating member 232 is activated; when the sensors sense the vehicle approaching and the driver still puts on changing line signal, the red illuminating member 232 is activated.
Moreover, the illuminating member 232 is a LED lamp.
In actual use, the warning unit 20 is connected to the sensors on both sides of the vehicle. When the rear vehicle enters the blind spot area of the backview mirror 10, the illuminating member 232 can be illuminated by the induction of the sensors, so that the emitted light can be emitted from the translucent region 121 of the mirror 12, to achieve the warning effect to the driver to pay attention. When the illuminating member 232 lights up, it uses the surface of the illumination rod 222 to diffuse the light diffuses evenly around, and the light is emitted from the translucent plate 221 through the translucent region 121.

Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of invention as hereinafter claimed.
