Description

Light guide license plate lamp

This creation is about a light-guide license plate lamp, especially a light-emitting source that emits light toward the outside of the vehicle, so that the light emitted by the light-emitting source is reflected by the light-guide total reflection lamp housing, which can be turned to evenly reflect and illuminate the license plate. In order to allow others to more clearly identify the number on the license plate, and in the overall implementation of the use of more practical and functional characteristics of the light guide license plate lamp innovative designer.

By the way, all kinds of vehicles can greatly shorten the time it takes for people and various objects to travel between the two places, and can enhance the convenience of people’s daily life and the transportation of various goods. It can be said to be one of the essential supplies in the lives of every household. ; In order to facilitate the identification of different vehicles, each vehicle driving on the road needs to install a license plate issued by the management agency at a specified position, and the position of the vehicle license plate required to be installed is between the front and the rear of the vehicle. The position where the license plate is required to be installed on the locomotive is at the middle position behind it.

Among them, in order to be able to clearly identify the license plate number on the license plate in the dark at night, the regulations require a license plate lamp to be installed at the corresponding license plate, so that the license plate can be illuminated by the bright light emitted by the license plate so that others can clearly Watch and learn the license plate number marked on the license plate.

However, although the above-mentioned license plate lamp can emit bright light to achieve the expected effect of illuminating the license plate, it is also found in its actual application that this type of license plate lamp is installed above the license plate and only makes the license plate light emit light. The downward light source illuminates the license plate, causing the beam to be too concentrated and poorly uniform, and it is impossible to illuminate the license plate evenly, which affects the recognition of the license plate by others, resulting in the overall structural design of the license plate. There is room for improvement.

The light source (2) is arranged corresponding to the light incident surface (122) of the total reflection lens (12) of the light guide total reflection lamp housing (1), and the light source (2) can be an LED.

The assembling base (3) is assembled with a cover cover outside the light guide total reflection lamp housing (1) and the luminous source (2).

In this way, please refer to the three-dimensional structure diagram of the use state of the fourth picture creation and the side view structure diagram of the use state of the fifth picture creation together, so that the creation can be used for operation and use of the light guide. The lamp housing (11) of the reflector lamp housing (1) is correspondingly arranged behind the outer edge of the license plate, so that the luminous source (2) is directed toward the incident light of the total reflection lens (12) of the light guide total reflection lamp housing (1) The surface (122) emits illuminating light. After the light emitted by the light-emitting source (2) is irradiated into the total reflection lens (12) through the light incident surface (122), the light can pass through the total reflection lens (12). The total reflection surface (121) reflects, and since the total reflection surface (121) of the total reflection lens (12) is formed with the recess (1211) in the middle, the light is irradiated to the total reflection in the state of equiangular distribution The surface (121), after being reflected by the total reflection surface (121), will result in sparse light in the middle and denser light on both sides, so that the total reflection surface (121) can allow the reflected light to be in the recess (1211) The reflected light intensity is lower, and the reflected light intensity on both sides of the concave portion (1211) is increased, so that the light reflected by the total reflection surface (121) can be more uniformly reflected and dispersed, and the light is redirected by the total reflection lens (12) The light emitting surface (123) at the bottom is uniformly irradiated and then irradiated on the license plate through the lamp housing (11) to achieve the uniform lighting effect required for the license plate.
