Description

Car lamp using surface light source

Technical Field

With the increasing improvement of the living standard and aesthetic ability of current consumers, the automobile lamp not only has the function of lighting, but also plays a role of drawing dragon eyes in modeling; therefore, lamp modelers are constantly changing in shape to cater for the aesthetic appeal of the current public; however, it is a focus problem to realize the lighting of the signal lamp and the optimal lighting state required by the modeling of the lamp.

In order to realize the lighting and light-equalizing effect required by the modeling of the signal lamp, the design of the current common scheme comprises an outer lampshade, a decoration frame, a light-emitting surface required by the modeling, a light guide piece, an LED chip and a PCB; in order to realize the lighting light-equalizing effect required by the modeling of the car lamp, the LED chip welded and packaged on the PCB emits light, the light beam penetrates through the inside of the light guide piece, the light beam is uniformly dispersed to strike on the light emitting surface through refraction and reflection inside the light guide piece, and the effect of lighting light-equalizing is presented by the outer lampshade of the rethread. In addition, another common design scheme is that the LED chips fixed on the PCB are arranged right behind the light guide piece, and the realization principle is similar.

For example, when a range of "1 to 5" is disclosed, the described range should be interpreted to include the ranges "1 to 4", "1 to 3", "1 to 2 and 4 to 5", "1 to 3 and 5", and the like. When a range of values is described herein, unless otherwise stated, the range is intended to include the endpoints thereof and all integers and fractions within the range.

In addition, the indefinite articles "a" and "an" preceding an element or component of the utility model are not intended to limit the number requirement (i.e., the number of occurrences) of the element or component. Thus, "a" or "an" should be read to include one or at least one, and the singular form of an element or component also includes the plural unless the stated number clearly indicates that the singular form is intended.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "front", "rear", and the like indicate orientations or positional relationships based on orientations or positional relationships shown in the drawings or orientations or positional relationships that are conventionally placed when the products of the present invention are used, and are merely used for convenience of description and simplification of the description, but do not indicate or imply that the devices or elements to be referred to must have specific orientations, be constructed in specific orientations, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.

The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The present invention is illustrated by the following specific embodiments, but is not limited to the specific examples given below.

The utility model provides a vehicle lamp in a first aspect, which comprises an outer lampshade, a luminous surface and a surface light source; the surface light source is positioned right behind the light emitting surface, and the outer lampshade is positioned right in front of the light emitting surface; the surface light source is fixed on the substrate in an undetachable manner.

As a preferred embodiment, the surface light source includes an LED chip and a silica gel, and the silica gel is fixed on the LED chip in a non-detachable manner.

In a preferred embodiment, an LED chip is provided directly in front of the substrate.

As a preferred embodiment, the silica gel comprises a light-homogenizing powder; therefore, the light beam emitted by the surface light source is completely uniform in light effect, and the light beam is not coupled by an additional light guide piece. The light beam emitted by the surface light source is completely and uniformly dispersed to strike the light emitting surface, and then the effect of uniform lighting is achieved through the outer lampshade. By using the surface light source, a thick-wall part or a light guide part can be omitted, and the space and the weight of the lamp are saved, so that the light-weight design required by customers can be achieved.

In one embodiment, the fixing of the surface light source to the substrate includes welding, riveting or bonding.

As an embodiment, the substrate includes FR4 board, ceramic board, fiberglass board or aluminum board, or a rigid substrate and a flexible PCB board covered on the rigid substrate are used.

In one embodiment, the distance between the outer lamp cover and the surface light source is 9mm-12 mm.

As an embodiment, the lamp fixture further includes a decoration frame, and the decoration frame is connected to an inner surface of the outer cover.

The working principle is as follows: when the automobile lamp works, the surface light source fixed on the substrate emits light, and because the surface light source directly encapsulates the LED chip on the substrate, the silica gel is fixed on the LED chip, and finally the silica gel and the substrate are encapsulated into a whole. Therefore, the light beam emitted by the surface light source is completely uniform in light effect, and the light beam is not coupled by an additional light guide piece. At the moment, light beams emitted by the surface light source completely and uniformly spread on the light emitting surface, and then the effect of uniform lighting is achieved through the outer lampshade.
