The utility model discloses technical scheme as follows: the utility model provides an automobile door handle illuminator, includes door handle sheet metal component, leaded light spare and light source chip, the door handle sheet metal component includes outside spare and interior side spare, leaded light spare set up in between outside spare and the interior side spare and in form the light emitting area between outside spare and the interior side spare, leaded light spare includes the leaded light body, the front and back side of leaded light body with outside spare and interior side spare are connected, the top surface of leaded light body is the light emitting area, the top surface of leaded light body is equipped with a plurality of wedge type distribution grooves, the oblique side of wedge type distribution groove is the scattering surface, the side of leaded light body is equipped with the spotlight cup, the front end side orientation of spotlight cup the leaded light body sets up, the axis of spotlight cup with the crossing setting of oblique side, the light source chip set up in the rear end side of spotlight cup.

Further, when the length of the automobile door handle is long or light rays with different colors need to be configured, the light gathering cups are arranged on two side faces of the light guide body.

Further, the wedge-shaped light distribution grooves are arranged in parallel at equal intervals.

Furthermore, the inclined side surface of the wedge-shaped light distribution groove is provided with a grid-shaped bulge.

Further, the light guide body and the light gathering cup are integrated.

The utility model provides a technical scheme's advantage lies in:

1. the light source chip is laterally arranged on the side face of the light guide part, the length of the doorknob is fully utilized to prolong a light path, and the scattering effect of the wedge-shaped light distribution groove is matched to achieve the effect of uniform light emission;

2. the integrated light guide part is embedded between the inner side sheet metal part and the outer side sheet metal part, so that the structure is simple and the installation is convenient;

3. the both sides of leaded light spare all can set up light source chip, adopt different colours and activate under the door different states as light source chip, can set up light in a flexible way and satisfy different user demands.

Detailed Description

The present invention is further described in connection with the following examples, which are intended to illustrate the invention and not to limit the scope of the invention, which, after reading the present invention, are intended to cover modifications of the invention in its various equivalent forms by those skilled in the art, which fall within the scope of the appended claims.

Referring to fig. 1 to 3, the light-emitting device for the door handle of the present embodiment includes a door handle sheet metal member 1, a light guide member 2 and a light source chip 3, wherein the door handle sheet metal member 1 includes an outer member 101 and an inner member 102. In the present embodiment, the light emitted from the door handle is top-emitting, so that the outer member 101 and the inner member 102 are combined to leave a light emitting gap in the upper portion of the door handle. The light guide 2 is disposed between the outer member 101 and the inner member 102 and forms a light emitting surface at a position of the light exit gap, that is, the top surface of the light guide 2 is a light emitting surface.

The light guide 2 includes a light guide body 201 and a light collection cup 202, and the light guide body 201 and the light collection cup 202 are integrally formed. The light guide body 201 is provided with light collecting cups 202 on both left and right sides thereof. The overall shape of the light guide body 201 matches the shape of the space between the outer member 101 and the inner member 102 of the door handle sheet metal member 1. The top surface of the light guide body 201 is provided with four wedge-shaped light distribution grooves 203, and the four wedge-shaped light distribution grooves 203 are arranged in parallel at equal intervals. As shown in fig. 4, the inclined side surface 203a of the wedge-shaped light distribution groove 203 is a scattering surface provided with grid-shaped protrusions 203 b. The front end side of the light collection cup 202 is disposed toward the light guide body 201, the axis of the light collection cup 202 intersects with the inclined side surface 203a of the wedge-shaped light distribution groove 203, and the light source chip 3 is disposed at the optical origin position on the rear end side of the light collection cup 202. The light source chips 3 on the left and right sides of the light guide body 201 may use LED chips of different colors, such as red and green, which may be independently lit to make the door handle appear red or green. As shown in fig. 5, the light emitted from the light source chip 3 enters the light guide body 201 through the light condensing action of the light condensing cup 202 and is emitted to the inclined side surface 203a of the wedge-shaped light distribution groove 203, and is emitted from the opening of the wedge-shaped light distribution groove 203 through the refraction action of the inclined side surface 203a, or is emitted to the inclined side surface 203a of another wedge-shaped light distribution groove 203, so that a uniform light emission is formed on the top surface of the entire light guide 201. When the light source chips 3 with different colors are adopted in the embodiment, the closing state of the door of a door closer is prompted by controlling the different colors of light, for example, when the door is closed, the door is closed tightly, and green light is emitted; the door is not closed or tightly closed, the red light is emitted, the light emitting time can be uniformly set to be 10 seconds and the like, so that the state of the door is prompted to a user, the requirements of peripheral light of a welcome and the requirements of appearance atmosphere are met, and the functions are expanded.
