Abstract

A turn signal lamp device uses a laser to implement sequential lighting of a turn signal. A plurality of optical lenses are horizontally arranged and applied to a turn signal lamp, and a laser source module is subjected to angular rotation by an actuator mounted at a rear portion of the turn signal lamp. Thereby, a laser source sequentially irradiates light onto the optical lenses while rotating at a predetermined angle, easily implementing sequential lighting of the turn signal lamp.

Claims

1. A turn signal lamp device using laser, comprising:

a plurality of optical lenses arranged horizontally and applied to a turn signal lamp;

a laser source module bearing a laser source; and

an actuator mounted at a rear portion of the turn signal lamp and arranged to subject the laser module to angular rotation;

such that a laser source sequentially irradiates light onto the optical lenses while rotating at a predetermined angle.

2. The turn signal lamp device of claim 1, wherein the optical lens is employed as a solid optical type lens including a condensing groove part for condensing the light of the laser source and a rear distribution body provided to a form gradually extended in the external direction from the condensing groove part to diffuse the light.

3. The turn signal lamp device of claim 1, wherein the actuator is employed as a rotary type actuator to perform repetitive lateral angular rotation at a predetermined angle on the laser source module, to be fixedly mounted in a lamp housing.

4. The turn signal lamp device of claim 1, wherein the laser source module includes:

a laser source protection case mounted to perform angular rotation about the rotational axis of the actuator; and

a laser source fixedly mounted inside the laser source protection case, to sequentially irradiate light onto the optical lenses while rotating at a predetermined angle equal to the rotational angle of the laser source protection case.

5. The turn signal lamp device of claim 4, wherein a light source irradiation hole having a size where the light of the laser source is irradiated onto one or two optical lenses is formed in the laser source protection case so that the light of the laser source passes through the laser source protection case.
