In addition, the light source normally emits green light, but when an event as described above occurs, it emits red light.

The base plate 130 may use a PCB substrate on which a circuit pattern is printed so as to apply a power signal to the light source 140.

As shown, only one light source 140 may be disposed in the center of the base plate 130, or a plurality of light sources 140 may be disposed in a predetermined pattern. In this case, it is preferable that the diverging portions 111 to be described later are also formed at positions corresponding to the positions of each light source 140.

The second groove 111B is formed to accommodate the light source 140.

Light emitted from the light source 140 toward the second groove 111B is emitted while passing through the inner circumferential surface of the first groove 111A, and passes through the inner circumferential surface of the first groove 111A to pass through the second groove 111B. The light traveling toward the inner circumferential surface of is radiated again while passing through the second groove 111B.

On the outer circumferential surface of the radiating part, the light emitted from the light source 140 in a direction toward the outer circumferential surface of the radiating part reflects so as to proceed to the upper part of the upper cover 110, and the solar light proceeding toward the light source 140 is transmitted to the solar cell 150.

As shown in the drawing, sunlight reaching the focusing portion of the upper cover 110 is refracted while passing through the curved surface of the first lens 115A to be focused to the solar cell 150. That is, as the sunlight incident on the curved surface of the first lens 115A goes upward from a near point adjacent to the bottom surface of the upper cover 110, the incident angle of the first lens 115A relative to the curved surface and the refracted angle of refraction are relatively As it grows, sunlight is focused.

Meanwhile, another embodiment of an alarm lamp is shown in FIG. 7.

Third lenses 117 having a are formed alternately along an extension line passing through the center of the upper cover 110 at one side of the upper cover 110.

Each inclined surface 117B may have different inclinations by setting the top height of each vertical surface 117A equally and increasing the length of the inclined surface 117B extending downward. Sunlight incident on each inclined surface 117B having different inclinations at different angles of incidence is focused by being refracted at different angles of refraction.

9 and 10 illustrate another embodiment of an alarm lamp.

9 and 10, the upper cover 110 of the alarm lamp is formed to be inclined with respect to the lower end of the upper cover 110 to increase the incident area of sunlight, and a position corresponding to the position of the light source 140 A diverging portion 111 extending downward from the bottom surface of is formed.

The fourth lenses 118 may be formed to extend from the upper cover 110, or otherwise separately manufactured ones may be attached.

When the height of the sun is increased by the upper cover 110 formed inclined as shown, the incident angle of sunlight incident on the upper cover 110 can be reduced and the amount of sunlight incident on the upper cover 110 can be increased. In addition, it is possible to focus sunlight through a focusing unit including the plurality of fourth lenses 118, thereby increasing power generation efficiency.

Since the above-described alarm lamp operates based on electric energy produced using sunlight, even if a power outage occurs, a nearby manager can easily grasp the alarm signal by the alarm lamp.

According to the present invention described above has been described with reference to the accompanying drawings, but this is only exemplary, and those of ordinary skill in the art will understand that various modifications and other equivalent embodiments are possible therefrom. .
