Background
Signage is an important indicator for businesses and products. For example, a sign is provided on an automobile or the like to display the brand of the automobile.
However, the existing signs are generally incapable of emitting light, displaying at night, and meeting the needs of people.
To this end, a sign capable of emitting light has been invented. As shown in fig. 1-3, the prior art illuminated sign includes an outer cover 1, an inner lens 2, a Printed Circuit Board Assembly (PCBA)3, a housing 4, and a heat sink 5. Wherein, the housing 1 is provided with a logo area 6, for example, a logo "BYD". A plurality of LEDs 7 are provided on the printed circuit board assembly 3. Typically, the plurality of LEDs 7 will be interspersed throughout the printed circuit board assembly 3. Wherein, the plurality of LEDs 7 emit light and then are diffused by the inner lens 2, and then the light effect is displayed by the outer cover 1.
However, the conventional luminescent sign employs LED light sources, and the number of LED light sources is large, and the LED light sources are distributed over the printed circuit board assembly. This makes the circuit design relatively complex on the one hand and relatively costly on the other hand. Meanwhile, the LED light source generates heat more severely, and therefore, a heat sink needs to be equipped. This results in a luminous sign which is relatively thick and heavy and is not easy to mount.
In view of the above technical drawbacks of the prior art, there is a need to develop a new type of luminous sign.
Disclosure of Invention
An object of the utility model is to overcome the shortcoming that exists among the prior art, provide a sign light-emitting structure, its cost is lower, and it is more convenient to install.
In order to achieve the above object, the present invention provides the following technical solutions:
the utility model provides a sign light-emitting structure, its includes dustcoat and casing, be equipped with logo pattern region on the dustcoat, logo pattern region is made by printing opacity or semi-transparent material, its characterized in that, be equipped with printed circuit board assembly between dustcoat and the casing, printed circuit board assembly with COB light source or LED array just have on the region that logo pattern region is relative the arrangement shape of COB light source or LED array with the shape of logo pattern region is the same.
Preferably, an inner lens is further disposed between the outer cover and the printed circuit board assembly.
Preferably, the inner lens is an inner lens capable of uniformly diffusing the light emitted by the COB light source or the LED array.
Preferably, the area of the outer cover except for the logo pattern area is made of an opaque material.
Preferably, wherein, the outer surface of the logo pattern region of the outer cover is plated with a metal layer or an alloy layer, or a translucent resin material.
Preferably, wherein the housing and the shell are hot plate or ultrasonically welded together.
Preferably, wherein the outer cover and the housing are joined together by hot melt adhesive.
Compared with the prior art, the utility model discloses a sign light-emitting structure has following beneficial technological effect:
1. it penetrates directly through COB light source or the LED array of the same shape with logo pattern area, perhaps does the inner lens light-emitting of scattering a little, and optical utilization is higher, does not need heat radiation structure for whole product is lighter, and is thinner, and the use of easy to assemble.
2, it adopts COB light source or other surface light source technology (such as LED array) same as the luminous pattern, so the number of light source is less than that of the prior art, and the circuit design is simplified
3. Because COB and area light source and base plate direct contact radiating efficiency are higher, it does not need customized radiator, therefore, its cost is lower.

Detailed Description
The present invention is further described with reference to the following drawings and examples, which are not intended to limit the scope of the present invention.
The utility model relates to a sign light-emitting structure, it is used for the brand of the mode show enterprise or product with light to be convenient for observe night.
As shown in fig. 4-6, the illumination structure of the label of the present invention comprises a housing 1 and a case 4. The housing 1 and the shell 4 are fixedly connected together.
Preferably, wherein the housing 1 and the shell 4 are welded together by hot plate or ultrasonic welding. Alternatively, the outer cover 1 and the housing 4 are joined together by hot melt adhesive. In this way, the connection between the cover 1 and the housing 4 is more secure and the integrity is stronger after finishing.
Wherein, a logo pattern area 6 is arranged on the outer cover 1. The logo design area 6 is used for displaying a logo of an enterprise or product, for example, a popular logo in fig. 5.
The logo pattern region 5 is made of a transparent or semi-transparent material so that light emitted by the light source can penetrate through the logo pattern region. The region of the outer cover 1 except the logo pattern region 6 is made of opaque material. In this way, light emitted from the light source can only be transmitted out of the logo pattern area 6, thereby showing the shape of the logo.
Preferably, the outer surface of the logo pattern area 6 of the outer cover 1 is plated with a metal layer or an alloy layer, or a translucent resin material. Thus, when the light source does not emit light, the inner parts cannot be seen through the logo pattern region 6, and the beauty is improved.
A printed circuit board assembly 3 is provided between the housing 1 and the housing 4.
Wherein, it is different with a plurality of LED light sources that adopt among the prior art to be covered with whole printed circuit board assembly the utility model discloses in, as shown in fig. 6, printed circuit board assembly 3 only has COB light source or LED array 7 on the region relative with logo pattern region 6. And, the arrangement shape of the COB light source or LED array 7 is the same as or similar to the shape of the logo pattern area 6. For example, the logo pattern area 6 is a popular logo, and thus, the arrangement shape of the COB light source or LED array 7 is also a popular logo.
Because the COB light source or the LED array which are in the same shape as the logo pattern area are adopted for direct projection, the optical utilization rate is higher, a heat dissipation structure is not needed, and the whole product is lighter, thinner and convenient to install and use. Moreover, after the COB light source or the LED array is changed, compared with the prior art, the number of the LEDs fully distributed on the whole printed circuit board assembly is less, and the circuit design is simplified. The reduction of the number of the parts is lower than the cost of the prior art.
Furthermore, in the present invention, preferably, an inner lens 2 may be disposed between the outer cover 1 and the printed circuit board assembly 3. The inner lens 2 is used for astigmatism.
More preferably, the inner lens 2 is a color inner lens. In this way, the inner lens 2 can broaden the range of COB light sources or LED arrays, resulting in lower cost.
The above embodiments of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. Not all embodiments are exhaustive. All obvious changes or variations led out by the technical scheme of the utility model are still in the protection scope of the utility model.
