Description

  The present invention relates to a reflection / light emission sheet for a bumper, and more particularly to the design of an original structure in which a built-in reflection plate is added.

  In order to improve the safety of night driving of automobiles, the related industry is continuously researching and developing issues to improve the reflection mechanism outside the car body. As can be seen from the general experience, when driving a car at night, the tail light of the front car shines in normal conditions, and when the brakes are applied, the brake light to warn the rear car shines However, in some special cases, for example, when the taillight breaks down, the driver inadvertently forgets to turn on the taillight, or when the line of sight is bad due to heavy rain, the former brake is applied, but the tail of the front car If the car body is not clearly visible, the situation is very dangerous for the rear car.

  In light of this, in the industry, reflective sheets are now attached to both sides of the bumper of an automobile. As a conventional device related to this, the “reflective light emitting sheet for bumpers” created by the inventor of the present invention was created. There is a new Taiwan patent proposal (registration number M308204).

  The previous idea mainly consists of a reflective panel, a pedestal, and an LED light emitting unit. Originally, a reflective sheet for a bumper has a light emitting warning effect and is integrated with other warning lights in a car. By adding it or adding it, the light beam from the outside can be made into a planar reflection effect through the reflection / light emission sheet.

  However, in a general situation, the LED light emitting unit achieves a main light emitting effect, and a warning effect that combines reflection and light emission. The inventor of the present invention has continued the research and development in order to improve the structure of the previous plan, and has the following problems and disadvantages in the conventional bumper reflective / emission sheet. I understood that.

  The light rays emitted from the LED light emitting unit inside the reflection / light emission sheet are dotted, and when the dotted rays from each LED reach the outside, the light is diffused by the reflection part of the reflection panel. Although the effect is achieved to some extent, since the uniformity of diffusion is limited, the light projection effect at the time of light emission of the reflection / light emission sheet cannot be realized to a uniformity that can be satisfied by the industry and users. The challenge remains to research and break through.

  Therefore, it is the user's demand to create an original structure that is more ideal and practical with respect to the problems that exist in the well-known conventional bumper reflective and luminescent sheet. It is also a goal and method that should continue to strive and break through.

  In view of this, the inventor has many years of experience in the manufacture, development and design of related products, and proposes the present invention with practicality after examining and studying the above-mentioned goals in detail.

  The main purpose of the present invention is to provide a reflection / light emission sheet for a bumper, and the problem to be solved is that the reflection sheet for a conventional bumper is only a reflection effect, and there is room for improvement and breakthrough. Quite a bit left. The reflection / light emission sheet includes a pedestal, a translucent casing, and an LED light emitting unit, and the pedestal includes a bumper assembly surface and a casing assembly surface. The translucent casing has a translucent surface and an assembly side, a reflective portion is provided inside the translucent surface, and a space is provided between the translucent casing and the pedestal. The LED light emitting unit is provided at a preset position of a placement space between the translucent casing and the pedestal.

  An object of the present invention is to provide a reflection / light emission sheet for a bumper that solves the above-described problems.

The present invention includes a pedestal, a translucent casing, an LED light emitting unit, and a built-in reflector.
The pedestal has a bumper assembly surface that is assembled at a preset location for an existing bumper on the inside, and a casing assembly surface on the outside.
The translucent casing has a translucent surface and an assembly side, has a reflecting portion inside the translucent surface, and the assembly side is assembled to the casing assembly surface of the pedestal body, and between the pedestal body, Forming a storage space,
The LED light emitting unit has a substrate, a plurality of LEDs, and a power cable, and is provided at a predetermined preset position in the placement space.
A built-in reflector is provided at a preset location of the placement space, and is opposed to the translucent surface of the translucent casing with a space therebetween, and reflects and diffuses light emitted from the LED. Has a surface.

  By providing the built-in reflecting plate, the light emitted from the LED is reflected and diffused by the reflecting surface. Compared to the conventional technology, this original design makes the light projection effect more uniform when the reflective light emitting sheet emits light, and further improves the quality of the reflective light emitting sheet. That is practical and inventive.

  Hereinafter, a reflection / light emission sheet for a bumper according to an embodiment of the present invention will be described. These examples are used for explanation only and are not intended to limit the scope of claims for utility model registration.
