Abstract
Description
Technical Field
[0001] The present invention relates to an LED side lamp for vehicles, and in particular to an LED side marker lamp having a starburst-shaped light pattern.
Background Art
[0002] In general, vehicles such as trucks, trailers and large transport vehicles have relatively long vehicle bodies, so the warning effect provided by vehicle lamps including the headlights arranged at the front of the vehicle and the rear lamps installed at the rear of the vehicle is mostly limited to the front and rear directions of the vehicle. Therefore, it is relatively difficult for other vehicles traveling on both the left and right sides of the vehicle, pedestrians walking near the vehicle, and riders driving vehicles to clearly recognize the position and traveling state of the vehicle. Especially at night, in bad weather such as rain or fog, when driving on curves, or in other environments with poor visibility, traffic accidents such as rear-end collisions caused by insufficient safety confirmation are more likely to occur. In order to improve the above situation, in addition to passive warning devices such as safety reflective sheets or safety reflective stickers currently mounted on the side of the vehicle body, there are also configurations in which an LED side marker lamp is mounted on the side of the vehicle body. The active light emission method using LEDs enhances the warning effect for the vehicle, thereby achieving the purpose of improving driving safety.
[0003] However, while the above-mentioned LED side marker lamps can provide a relatively good warning effect through active illumination, allowing surrounding road users to recognize the vehicle's position, their light output method mostly consists of point-like light sources or uniform light patterns. As a result, the overall light pattern is relatively uniform, and in complex traffic environments, environments with interference from surrounding light sources, or environments with low visibility, it is difficult to make the presented light pattern stand out from the surrounding light sources. This makes it difficult for surrounding vehicles, pedestrians, or riders to clearly recognize the vehicle's position within a relatively short time. In addition, in recent years, many LED side marker lamps have attracted attention for their light guide structures and lamp cover optical structures that can guide the light rays and provide uniform light output. However, they have the problem that it is impossible to produce a warning effect with a special light pattern that matches the arrangement of the LEDs, and there is still room for improvement in their visibility and warning effect to the vehicle. [Overview of the project] [Problems that the invention aims to solve]
[0004] This invention has been made in view of the above-mentioned problems, and its purpose is to provide an LED side marker lamp having a starburst-shaped light pattern emitted by the cooperation of the arrangement of LEDs, the light guide frame, and the optical structure of the lamp cover, thereby improving driving safety by enhancing visibility when the vehicle is driving at night or in environments with low visibility. [Means for solving the problem]
[0005] To achieve the above objective, the LED side marker lamp having a starburst-shaped light pattern according to the present invention is provided for mounting on a vehicle body and comprises a lamp base, a lamp plate, a light guide frame, and a lamp cover. The lamp plate is installed within the lamp base and is provided with a drive electrical circuit and a plurality of LEDs. The drive electrical circuit includes a plurality of electrical resistors and a plurality of constant voltage diodes electrically connected to the plurality of LEDs, and the plurality of LEDs are arranged and installed at the center and peripheral parts of the lamp plate, respectively. The light guide frame is installed within the lamp base and covers the lamp plate. The light guide frame has a plurality of light guide parts corresponding to a portion of the plurality of LEDs, and each light guide part is used to form a starburst-shaped light pattern by receiving and guiding the light rays emitted from each of the LEDs. The lamp cover is connected to the lamp base and covers the lamp plate and the light guide frame. [Effects of the Invention]
[0006] According to this invention, by cooperating with the arrangement of the plurality of LEDs on the lamp plate, the plurality of light guides on the light guide frame, and the optical structure of the lamp cover, the light rays emitted from each LED are guided to pass through the light guide frame, and refraction and diffusion occur in accordance with the optical structure of the lamp cover, thereby producing a light output effect having a starburst-shaped light pattern. The resulting starburst-shaped light pattern can be made to stand out more from surrounding light sources and has a relatively favorable visual recognition effect, thereby improving visibility when the vehicle is driving at night or in environments with low visibility, and increasing the attention of drivers who are fatigued in front, to the side, and behind (including other road users such as other drivers, pedestrians, and motorcyclists), thereby improving the warning effect on the vehicle and driving safety.

[Figure 4] This is a schematic diagram showing the light output of a light guide frame according to a second preferred embodiment of the present invention. [Figure 5] This is a partially exploded schematic diagram of a third preferred embodiment of the present invention. [Modes for carrying out the invention]
[0008] The details of this invention will be clearly understood by those with ordinary skill in the art through the following description, with reference to the attached drawings.
[0009] (First embodiment) Refer to Figure 1, which is a partially exploded schematic diagram of a first preferred embodiment of the present invention. As shown in the figure, an LED side marker lamp 1 having a starburst-shaped light pattern is provided for mounting on a vehicle body (not shown), and comprises a lamp base 10, a lamp plate 11, a light guide frame 12, and a lamp cover 13. The lamp plate 11 is installed in the lamp base 10, the light guide frame 12 is installed in the lamp base 10 and covers the lamp plate 11, and the lamp cover 13 is connected to the lamp base 10 and covers the lamp plate 11 and the light guide frame 12.
[0010] The lamp plate 11 is provided with a drive electrical circuit 110 and a plurality of LEDs 111. The drive electrical circuit 110 is electrically connected to the plurality of LEDs 111 and includes a plurality of electrical resistors 1100 and a plurality of constant voltage diodes 1101. The plurality of LEDs 111 are arranged and installed at the center and peripheral parts of the lamp plate 11, respectively. The light guide frame 12 has a plurality of light guide parts 120 corresponding to a portion of the plurality of LEDs 111. Each light guide part 120 receives and guides the light rays emitted from each LED 111, thereby forming a starburst-shaped light pattern, which can increase the attention of a driver who is fatigued, looking to the side, front, and rear.
[0011] (Second embodiment) Refer to Figures 2 to 4, which are schematic diagrams showing the light output of the light guide frame of the second preferred embodiment of the present invention, respectively: Partially exploded schematic diagram (1), Partially exploded schematic diagram (2) of the second preferred embodiment of the present invention. As shown in the figures, the LED side marker lamp 1 having a starburst-shaped light pattern comprises a lamp base 10, a lamp plate 11, a light guide frame 12, and a lamp cover 13. It is provided for mounting on a vehicle body (not shown) to provide warning illumination on the side of the vehicle body, thereby enhancing the recognition effect of the vehicle body's position to surrounding road users. The lamp plate 11 is installed in the lamp base 10, the light guide frame 12 is installed in the lamp base 10 and covers the lamp plate 11, and the lamp cover 13 is connected to the lamp base 10 and covers the lamp plate 11 and the light guide frame 12.
[0012] The lamp plate 11 has an octagonal plate shape and is provided with a drive electrical circuit 110 and a plurality of LEDs 111. The drive electrical circuit 110 is electrically connected to the plurality of LEDs 111 and includes a plurality of electrical resistors 1100 and a plurality of constant voltage diodes 1101. The plurality of electrical resistors 1100 and the plurality of constant voltage diodes 1101 are installed on one side of the lamp plate 11. Multiple LEDs 111 are arranged and installed in the center and peripheral areas of the lamp plate 11. Specifically, the multiple LEDs 111 include multiple first LEDs 111 installed in the center of the lamp plate 11 and multiple second LEDs 111 installed in the peripheral areas of the lamp plate 11. The multiple first LEDs 111 are arranged in a cross shape, and the multiple second LEDs 111 are arranged along the peripheral area of the lamp plate 11 at sequential intervals, surrounding the outside of the multiple first LEDs 111 in a ring shape. This provides different light output regions in the center and the periphery, making it easy to form a subsequent starburst-shaped light pattern.
[0013] The light guide frame 12 has multiple light guide sections 120, each corresponding to a portion of the multiple LEDs 111. Each light guide section 120 receives and guides the light rays emitted from each LED 111 to form a starburst-shaped light pattern. Specifically, multiple convex-tooth shaped light guide sections 120 are formed at intervals along the inner edge of the light guide frame 12, corresponding to the multiple second LEDs 111. Each light guide section 120 extends in an arc from the top of the light guide frame 12 toward the lamp plate 11 and covers the corresponding second LEDs 111 above, thereby receiving the light rays emitted from each second LED 111 and guiding them to output light toward the outside of the light guide frame 12. This allows multiple first LEDs 111 to jointly form a starburst-shaped light pattern, making the resulting light pattern stand out more from surrounding light sources and increasing the attention of fatigued drivers to the sides, front, and rear, thereby improving the warning effect on the vehicle.
[0014] In this embodiment, a plurality of first dots 130 are provided in the central region on the inside of the lamp cover 13, and these dots are associated with a plurality of first LEDs 111, with the first dots 130 being arranged in a hexagonal pyramidal shape or in a circular dot shape. For example, when they are arranged in a circular dot shape, a plurality of perforated marks 131 are provided on the inside of the lamp cover 13, discretely distributed outward from the periphery of this central region. A mesh pattern structure 133 corresponding to the plurality of first dots 130 is provided in the central region on the outside of the lamp cover 13. At least one of the following surfaces, for example, the inner surface of the lamp base 10, the inner surface of the lamp cover 13, the outer surface of the light guide frame 12, and the bottom surface of each light guide part 120, is provided with an optical prism array structure 14. For example, only the inner surface of the lamp base 10 is provided with this structure to refract and diffuse the light rays emitted from each LED 111, and the optical prism array structure 14 is a convex lens structure. At least one of the following surfaces, for example, the periphery of the lamp base 10, the outer surface of the light guide frame 12, and the periphery of the lamp cover 13, is provided with a wave pattern structure 15. For example, the periphery of the lamp base 10 and the periphery of the lamp cover 13 are provided simultaneously with a wave pattern structure 15. This guides the light rays emitted from each LED 111 to output light in a predetermined direction, and together with the light guide frame 12, a starburst-shaped light pattern is formed, further improving the recognition effect of the overall light pattern and the warning effect on the vehicle body.
[0015] (Third embodiment) Next, refer to Figure 5, which is a partially exploded schematic diagram of a third preferred embodiment of the present invention. As shown in the figure, a plurality of first dots 130 are provided in the central region on the inside of the lamp cover 13, and these dots correspond to a plurality of first LEDs 111, and the first dots 130 are arranged in a hexagonal pyramidal shape, and a plurality of circular dots 132 are arranged in a ring around the outer periphery of the plurality of first dots 130, and these dots correspond to a plurality of second LEDs 111. An optical prism array structure 14 may be formed on the inner surface of the lamp base 10, which refracts and diffuses the light rays emitted from each LED 111, and the optical prism array structure 14 is a convex lens structure. A wave-shaped pattern structure 15 may be provided on the outer circumference of the light guide frame 12. This guides the light rays emitted from each LED 111 to output light in a predetermined direction, and together with the light guide frame 12, a starburst-shaped light pattern is formed, further improving the recognition effect of the overall light pattern and the warning effect on the vehicle.
[0016] In summary, this invention, through the cooperation of the arrangement of multiple LEDs on the lamp plate, the multiple light guides of the light guide frame, and the optical structure of the lamp cover, guides the light rays emitted from each LED through the light guide frame and refracts and diffuses them in accordance with the optical structure of the lamp cover, thereby producing a light output effect with a starburst-shaped light pattern. As a result, the resulting starburst-shaped light pattern can be made more prominent from surrounding light sources and has a relatively favorable visual recognition effect, thereby improving visibility when the vehicle is driving at night or in environments with low visibility. This can increase the attention of drivers who are fatigued (including other road users such as other drivers, pedestrians, and motorcyclists) to the front, sides, and rear, thereby improving the warning effect on the vehicle and driving safety.
