Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.

According to the LED lighting device, based on the strip-shaped LED chips, if the single chips are horizontally arranged horizontally or vertically arranged, and the center-to-center distance value between the two longitudinal chips is equal to the center-to-center distance value between the two transverse chips, the difference between the minimum distance between the edges of the two longitudinal adjacent chips and the minimum distance between the edges of the two transverse adjacent chips is larger, so that the whole display surface is unevenly displayed, and the actual lighting effect is affected; and, it is also difficult to arrange in a triangular or sharp corner-like narrow area space of the screen.

Referring to fig. 1-3, an interactive lamp 1-1, comprising:

A mounting bracket 10;

The circuit board assembly 20 is positioned and assembled on the mounting bracket 10, and a light emitting chip array 21 is arranged on the surface of one side, far away from the mounting bracket 10, of the circuit board assembly 20;

A lens 30 disposed on a side of the circuit board assembly 20 away from the mounting bracket 10 and spaced apart from the circuit board assembly 20, wherein a display area 31 of the lens 30 is located in front of the light emitting direction of the light emitting chip array 21;

The light emitting chip array 21 includes a plurality of chip units 211 arranged at intervals along a first direction and a second direction, wherein an included angle between a length direction of the chip units 211 and the first direction or the second direction is an acute angle, and a center-to-center distance between two chip units 211 arranged along the first direction is substantially equal to a center-to-center distance between two chip units 211 arranged along the second direction.

Specifically, in the present application, the first direction is a transverse direction, and the second direction is a longitudinal direction. The included angle between the longitudinal direction of the chip unit 211 and the first direction or the second direction is an acute angle, i.e. the longitudinal direction of the chip unit 211 is an acute angle with respect to the arrangement direction. Taking a chip specification of 1.6mm×0.8mm as an example, the size of the effective light emitting surface is 1.15mm×0.6mm, the preset center-to-center distance between two chip units 211 arranged along the transverse direction and the preset center-to-center distance between two chip units 211 arranged along the longitudinal direction are both 2mm, at this time, the difference between the minimum distance S1 between the light emitting edges of two chip units 211 adjacent along the longitudinal direction and the minimum distance S2 between the edges of two chip units 211 adjacent along the transverse direction is obviously reduced, so that the light emitting uniformity of the light emitting chip array 21 along the transverse direction and the longitudinal direction can be kept consistent. It is to be noted that the substantially equal as described above means a case where the center-to-center distances of the two chip units 211 arranged in the first direction are equal to the center-to-center distances of the two chip units 211 arranged in the second direction, and the center-to-center distances of the two directions are slightly different within the production error range.

After the length direction of the chip unit 211 forms an acute angle relative to the arrangement direction, the chip unit 211 does not need to be propped against the corner inflection point position of the light emitting chip array 21 (or the display area 31 of the lens 30), thereby increasing the installation redundancy space, reducing the installation difficulty and improving the installation success rate; and the edges of the light emitting chip units 211 at the corners and the light emitting chip array 21 (or the display region 31 of the lens 30) are changed from surface contact to point contact, it is easier to arrange in a triangle of the screen or a narrow region space like a sharp corner.

Referring to fig. 5, in some embodiments, the center-to-center spacing of two chip units 211 is 2mm±0.5mm. The center distance value is small, the area of the whole screen can be reduced, and more choices are available in the whole-vehicle arrangement aspect.

Referring to fig. 4, in some embodiments, an angle between a length direction of the chip unit 211 and the first direction is 45 degrees, or an angle between the chip unit and the second direction is 45 degrees.

Taking the chip specification of 1.6mm×0.8mm as an example, the preset center-to-center distance between two chip units 211 arranged along the transverse direction and the center-to-center distance between two chip units 211 arranged along the longitudinal direction are both 2mm, and at this time, the minimum distance S1 between the edges of two longitudinally adjacent chips is basically consistent with the minimum distance S2 between the edges of two laterally adjacent chips, so that the light emitting uniformity of the light emitting chip array 21 along the transverse direction and the longitudinal direction can be kept completely consistent, and the light emitting effect is better.

Referring to fig. 1, in some embodiments, the display region 31 of the lens 30 is provided with at least one corner, and the light emitting chip array 21 is disposed corresponding to at least the corner of the display region 31.

After the length direction of the chip unit 211 forms an acute angle relative to the arrangement direction, the chip unit 211 does not need to be propped up to the inflection point position of the inflection point of the corner of the display area 31 of the lens 30, so that the installation redundancy space is increased, and the installation difficulty is reduced; and the edges of the light emitting chip units 211 at the corners and the light emitting chip array 21 (or the display region 31 of the lens 30) are changed from surface contact to point contact, it is easier to arrange in a triangle of the screen or a narrow region space like a sharp corner.

In a specific operation, the corners of the display area 31 may have smaller angles, and the redundant chip units 211 at the corners may be removed according to the actual shape of the display area 31, so as to adapt to different corner shapes of the display area 31, thereby being suitable for special modeling.

In some embodiments, the display area 31 of the lens 30 is translucent black. Specifically, when the display area 31 of the lens 30 is translucent black, the circuit board assembly 20 and other structures cannot be seen from the outside in the non-lighting state, which is beneficial to improving the aesthetic property in the non-lighting state; in the light-emitting interaction state, the light is filtered by the semitransparent black display area 31 and then is emitted to the outside, and the brightness is soft and not dazzling. The lens 30 can be made of PC material, and is light in weight and easy to handle.

In some embodiments, the chip unit 211 is a white light chip or a red light chip. White light can be emitted when the white light chip is adopted, and red light can be emitted when the red light chip is adopted, so that the use requirement of an interactive screen can be met.

Referring to fig. 1, in some embodiments, the lens 30 includes an opaque region 32, the opaque region 32 is disposed on the periphery of the display region 31, and the planar profile shape of the lens 30 substantially conforms to the planar profile shape of the display region 31. This makes it possible to fully utilize the planar space of the lens 30 and to increase the area of the display area 31 as much as possible.

Referring to fig. 2, in some embodiments, the planar profile of the mounting bracket 10 and the circuit board assembly 20 substantially corresponds to the planar profile of the display area 31, respectively. Thus, the mounting bracket 10 and the circuit board assembly 20 can be maximally arranged by fully utilizing the narrow triangular area between the lens 30 and the lamp body 40 so as to mount corresponding electronic components.

Referring to fig. 2, in some embodiments, further comprising: the lamp body 40 is arranged on one side of the mounting bracket 10 away from the circuit board assembly 20 and is used for accommodating the mounting bracket 10 and the circuit board assembly 20; the lens 30 is assembled with the lamp body 40. After the lamp body 40 and the lens 30 are combined, the interactive lamp 1-1 can form an independent sealing structure, so that the use safety is ensured. Of course, in other embodiments, the interactive lamp 1-1 may be directly attached to the vehicle body without limitation herein.

Referring to fig. 2, in some embodiments, the shape of the lumen of the lamp body 40 substantially conforms to the shape of the planar profile of the lens 30. As shown in the figure, the shape of the inner cavity of the lamp body 40 and the plane outline of the lens 30 are triangular, and the triangular mounting bracket 10 and the circuit board assembly 20 can be just embedded; the shape of the inner cavity of the lamp body 40 is not large, so that the vehicle body space is not additionally occupied.

It should be noted that the above-mentioned substantially uniform shape means: the shapes are identical and the two shapes are slightly different within the production error.

Referring to fig. 2, in some embodiments, the lamp body 40 is further configured to receive a control board 50; the control board 50 is located at a side of the mounting bracket 10 away from the circuit board assembly 20, and is connected to the chip unit 211 to control the chip unit 211 to emit light and to extinguish.

Specifically, the control board 50 can individually control the light emission and extinction of each chip unit 211 of the light emitting chip array 21, so that the light emitting chip array 21 assumes a desired pattern.

Referring to fig. 7-8, a vehicle 1 is provided comprising the interactive lamp 1-1. After the interactive lamp is adopted, the minimum distance between the edges of the two longitudinally adjacent chip units is basically consistent with the minimum distance between the edges of the two transversely adjacent chip units, so that the whole display surface is more uniform in display and the actual lighting effect is better; and also facilitates placement in a triangular or sharp corner-like narrow area space of the screen.

The above description is only of the preferred embodiments of the present application and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
