1. Field of the Invention
This invention relates to a reflective rear light for a truck, particularly to one composed of a light housing, a reflection plate and a lens. The light housing is formed integrally with a circuit board disposed thereon with a clearance light and side marker light region. The reflection plate consists of a side reflecting plate corresponding to the clearance light and side marker light region of the light housing. The lens has one side formed with a side light transmission region having its front side provided with a clearance light refraction region. The lens further has one inner side provided with a slot at a location near the side marker light transmission region for fitting a side reflector that is provided with a side light refraction region. By this design, the reflective rear light for a truck of this invention can be divided into several different warning light regions, not only able to illuminate a license plate but also reinforce an effect of projecting light on the truck width and side.
2. Description of the Prior Art
A conventional truck rear light, as shown in
The objective of this invention is to offer a reflective rear light for a truck formed integrally and divided into several different warning light regions to illuminate a license plate and reinforce effect of projecting light on truck width and side.
The truck rear light in the present invention includes a light housing formed integrally with a circuit board installed thereon with lots of LEDs and divided into a main light region, a clearance light and side marker light region and plural license plate light regions. The light housing is further fixed thereon with a positioning post. A reflection plate to be screwed together with the light housing consists of a main reflecting plate, plural license plate reflecting plates and a side reflecting plate, equipped with a threaded hole to be combined with the positioning post of the light housing. A lens to be covered on the light housing is disposed with a main light projection region, plural license plate transmission regions and a side light transmission region having its front side provided with a clearance light refraction region. The lens further has one inner side provided with a slot at a location near the side light transmission region for fitting a side reflector that is provided thereon with a side light refraction region.
This invention will be better understood by referring to the accompanying drawings, wherein:
A preferred embodiment of a reflective rear light for a truck in the present invention, as shown in FIGS., 2, 3 and 4, includes a light housing 1, a reflection plate 2 and a lens 3 as main components combined together.
The light housing 1 is formed integrally with a circuit board 10 installed thereon with lots of LEDs and divided into a main light region 11, plural license plate light regions 12 and a clearance light and side marker light region 13. The light housing 1 is further fixed thereon with a positioning post 14.
The reflection plate 2 to be screwed together with the light housing 1 consists of a main reflecting plate 21, plural license plate reflecting plates 22 and a side reflecting plate 23. The reflection plate 2 is equipped with a threaded hole 24 to be combined with the positioning post 14 of the light housing 1 by means of a screw (N). The main reflecting plate 21 is disposed with a plurality of recessed holes 210 corresponding to the main light region 11. The license plate reflecting plates 22 are respectively positioned at the lower opposite sides of the main reflecting plate 21, corresponding to the license plate light regions 12 on the circuit board 10. The side reflecting plate 23 is positioned near the exterior side of the main reflecting plate 21 at a location matching with the clearance light and side marker light region 13 on the circuit board 10.
The lens 3 to be covered on the light housing 1 is provided with a main light projection region 30, two license plate light transmission regions 31 and a side light transmission region 32 having its front side disposed with a clearance light refraction region 320. Further, the lens 3 has one inner side provided with a slot 33 at a location near the side light transmission region 32. A side reflector 34 provided thereon with a side light refraction region 340 is inserted in the slot 33 of the lens 3.
In assembling, referring to
With this design, the reflective rear light for a truck of this invention has the following advantages.
1. The main light region 11, the license plate light regions 12 and the clearance light and side marker light region 13 of the light housing 1 in cooperation with the main reflecting plate 21, the license plate reflecting plates 22 and the side reflecting plate 23 of the reflection plate 2 can function to divide illumination.
2. The integral circuit board 10 is installed thereon with lots of LEDs divided into several different warning light regions and having a large-area refraction effect with the help of the reflection plate 2.
3. The side reflector 34 inserted in one side of the lens 3 enables the clearance light to reinforce its reflection effect by refraction of both the clearance light refraction region 320 at the front side of the side light transmission region 32 and the side light refraction region 340 at one side of the side reflector 34, thus increasing light illumination area and reinforcing effect in recognizing the truck width and side signals.
While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
