As shown in fig. 1, the present embodiment provides a rear taillight, which includes a housing 1, an outer cover 2, an inner cover, a reflector and a light source 5, wherein the outer cover 2 is connected to the housing 1 and encloses a closed inner cavity with the housing 1; the inner lampshade is arranged in the inner cavity, and the side surface of the inner lampshade, which is far away from the outer lampshade 2, comprises a frosted surface; the reflector is arranged in the inner cavity and positioned on one side of the inner lampshade, which is far away from the outer lampshade 2, and the reflector comprises two arc-shaped reflecting parts 41; the light source 5 sets up in the inner chamber, and light source 5 includes circuit board 52 and a plurality of LED lamp 51, and a plurality of LED lamp 51 divide into two sets ofly, and two sets of LED lamps 51 set up respectively in the both sides of circuit board 52, and circuit board 52 is located between two arc reflector portions 41, and the light that every group LED lamp 51 sent can pass interior lamp shade and outer lamp shade 2 in proper order through the reflection of an arc reflector portion 41 and shine outside.

According to the rear tail lamp provided by the embodiment, the side surface of the inner lamp shade facing the reflector is the frosted surface, and when light passes through the frosted surface of the inner lamp shade, the frosted surface can perform diffuse reflection on the light, so that the light is reflected towards all directions, the uniformity of light emission is improved, the appearance fineness of lighting is improved, a thick-wall light guide with higher price is omitted, and the cost is reduced; two sets of LED lamps 51 are located the both sides of circuit board 52 respectively, make the light that launches from LED lamp 51 at first towards the direction propagation that deviates from circuit board 52, then two sets of light are all towards interior lamp shade direction propagation through the reflection of two arc reflection of light portions 41 respectively, on the one hand, the propagation path of two sets of light does not have the cross, on the other hand, circuit board 52 is between two arc reflection of light portions 41, the effect of sheltering from light has been played, make the light of two sets of reflections mutually noninterfere, luminous degree of consistency has further been improved. The circuit board 52 is used for electrifying the LED lamps 51, and two groups of LED lamps 51 are installed on one circuit board 52, so that the number of the circuit boards 52 is reduced, and the cost is further reduced. The rear tail lamp provided by the embodiment not only improves the uniformity of light emission, improves the appearance delicacy of lighting, but also can reduce the cost.

Specifically, the inner lamp housing includes two housing bodies 31, and the light reflected by each of the arc-shaped light reflecting portions 41 can pass through one of the housing bodies 31. The inner sides of the two cover bodies 31 are frosted surfaces, and the light rays reflected by the two arc-shaped light reflecting parts 41 are diffused and reflected by the frosted surfaces of the two cover bodies 31 respectively, so that the uniformity of light ray emission is further improved.

The rear taillight provided by this embodiment further includes a light blocking rib 6, the light blocking rib 6 is disposed between the two covers 31, and the light blocking rib 6 is connected to the circuit board 52. The light blocking ribs 6 further block mutual interference of light rays on two sides, and light channeling phenomenon when only the single-side LED lamp 51 is lightened can be prevented, so that the lightening appearance effect is further improved.

As shown in fig. 1 and 2, the light blocking rib 6 includes a main board 61 and two blocking plates 62, the two blocking plates 62 are respectively connected to two sides of the main board 61, the main board 61 is connected to the circuit board 52, one end of the cover 31 is connected to the arc-shaped light reflecting portion 41, and the other end is connected to one side of the blocking plate 62 facing the outer light housing 2. Mainboard 61 and circuit board 52 have played jointly and have blockked the effect that both sides light scurried each other, and setting up of baffle 62 can prevent that light from spouting from the space between two covers bodies 31, has guaranteed that light jets out again after carrying out diffuse reflection through the frosting of the cover body 31.

Alternatively, the end of the arc-shaped light reflecting part 41 connected with the cover 31 is a straight structure. The flat configuration increases the contact surface with the end of the cover 31, making the connection between the two more secure.

Specifically, the outer lamp cover 2 includes two light-transmitting portions 21, and each light-transmitting portion 21 faces one cover 31.
