Referring to fig. 1-6, the present invention provides a signal lamp 100.

The signal lamp 100 includes a light source assembly 1, a cylindrical lamp housing 2, and a bottom cover 3 and a top cover 4 respectively fixed to both ends of the lamp housing 2. The lampshade 2, the bottom cover 3 and the top cover 4 together enclose an accommodating space 10.

The light source assembly 1 is accommodated in the accommodating space 10. Specifically, the light source assembly 1 includes a circuit board 11 and a plurality of lamp beads 12.

The circuit board 11 is sheet-shaped. The circuit board 11 is used for controlling the state that the lamp bead 12 lights.

The lamp beads 12 are electrically connected with the circuit board 11. A plurality of the lamp beads 12 are installed on two opposite sides of the circuit board 11. In order to make the signal lamp 100 emit light uniformly and with a good light emitting effect, the plurality of lamp beads 12 are uniformly distributed on two opposite sides of the circuit board 11.

It should be noted that the circuit board 11 and the lamp bead 12 are both common devices in the art, and a specific model needs to be selected by a designer according to actual needs, which is not described in detail herein.

Specifically, the sub-lampshade 21 includes a bottom plate 211, a cylindrical side wall 212 bent and extended from a periphery of the bottom plate 211, and a reflector 213 fixed to the side wall 212.

The bottom plate 211 is used to fix the circuit board 11. Specifically, the bottom plate 211 is provided with a mounting hole 2110 penetrating therethrough. The circuit board 11 passes through the mounting hole 2110 and is fixed to the bottom plate 211. In this embodiment, the circuit board 11 passes through the three mounting holes 2110 of the sub-lamp housings 21, so that the plurality of lamp beads 12 are uniformly distributed in the three sub-lamp housings 21, and the signal lamp 100 has uniform light emission and a good light emission effect.

The side walls 212 are made of a light-transmitting material, such as glass or a light-transmitting plastic.

The outer surface of the sidewall 212 is provided with a plurality of annular light scattering rings 2121 arranged at intervals. The iris 2121 is used for light diffusion. The plurality of the light scattering rings 2121 are in a gear-shaped structure, and light emitted by the lamp beads 12 positioned on the inner side of the side wall 212 is uniformly diffused by the light scattering rings 2121, so that the light is directly emitted and the light brightness is high.

In this embodiment, in order to achieve uniform light diffusion of the iris 2121, the side wall 212 is provided with a plurality of inner wall grooves 2122 formed by recessing the inner surface thereof. A plurality of the inner wall grooves 2122 are symmetrically spaced. The inner wall grooves 2122 enhance the effect of uniform light diffusion of the light emitted by the lamp beads 12 through the light-diffusing ring 2121.

Preferably, the inner wall groove 2122 extends in an axial direction of the lamp housing 2. Meanwhile, the light scattering ring 2121 is arranged in a concentric circle along the axis, that is, the inner wall groove 2122 is perpendicular to the light scattering ring 2121, which makes the light scattering uniform. Of course, without limitation, the inner wall slot 2122 and the iris 2121 may be crossed to make the light spread uniformly, and the designer may make a specific choice according to the actual application.

The sidewall 212 is used for uniform light diffusion and also for connection fixation. Specifically, each of the side walls 212 is connected to an adjacent one of the side walls 212, so that the sub-lamp housings 21 are stacked to form a column.

In this embodiment, a locking portion 2123 and a fixing portion 2124 matching with the locking portion 2123 are respectively disposed at two ends of the side wall 212, and the locking portion 2123 and the adjacent one of the fixing portions 2124 are rotatably locked and fixed.

The reflector 213 includes two reflectors and is spaced apart from the two reflectors at opposite sides of the light source assembly 1. The light beads 12 are opposite to the reflector 213 so that the reflector 213 can emit the light from the light beads 12 through the diffuser 2121. The structure enables the intensity of light emitted by the lamp bead 12 to be kept high through the ejection of the light scattering ring 2121, and simultaneously enables the light emitted by the lamp bead 12 to have a good light diffusion effect through the light scattering ring 2121.

Specifically, the reflector 213 includes a reflector body 2131 spaced apart from and facing the circuit board 11, and two extending portions 2132 extending from two opposite ends of the reflector body 2131 to the side walls 212. This structure can make the reflecting area of the reflecting frame 213 in the accommodating space 10 large and the reflecting effect good.

In order to enhance the light diffusion uniformity and the light intensity effect, in the present embodiment, a plurality of recessed light reflecting grooves 2130 are formed on two opposite sides of the light reflecting frame 213. The reflective groove 2130 increases the reflective area and has good reflective effect. The reflective groove 2130 extends in the axial direction of the lamp housing 2. The structure is matched with the inner wall groove 2122 structure of the side wall 212, so that the light emitted by the lamp bead 12 has a good effect of uniform light diffusion through the light scattering ring 2121.

The lever 5 is fixed to the bottom cover plate 32 and has one end inserted into the wire hole 30. The rod 5 is provided with a wire passage 50 running through it in its axial direction for the introduction of external electrical wires. This configuration makes the signal lamp 100 highly reliable and aesthetically practical.

In this embodiment, the signal lamp 100 further includes a buzzer 6 mounted on a side of the bottom cover plate 32 away from the lamp housing 2. The buzzer 6 is arranged at an interval with the rod 5. The buzzer 6 is used for the signal lamp 100 to send out alarm sound.
