In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below with reference to the accompanying drawings in combination with specific embodiments.

"upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.
In one embodiment, as shown in fig. 1, a light emitting device includes: the LED lamp comprises a first light-emitting area and a second light-emitting area, wherein the first light-emitting area is arranged around the periphery of the second light-emitting area; the first light-emitting area comprises a first light-emitting unit and a second light-emitting unit which are arranged back to back, and the light-emitting directions of the first light-emitting unit and the second light-emitting unit are opposite; at least one of the first light emitting unit and the second light emitting unit includes: a package cover; at least two light emitting elements covered in the package cover; the light emitting elements are provided with light emitting angles, a first distance is reserved between every two adjacent light emitting elements, a second distance is reserved between the light emitting surfaces of the light emitting elements and the light emitting surface of the packaging cover, and the second distance is determined based on the first distance and the light emitting angles.
The first light-emitting unit and the second light-emitting unit of the first light-emitting area realize double-sided light emission of the first light-emitting area.
For the first light-emitting zone 1, first a selection is made for the first light-emitting unit and/or the second light-emitting unit. For a person with normal or corrected vision (1.0 or 5.0), the limiting viewing angle that the human eye can resolve between the two adjacent nearest points of the object being viewed is 1'-1.5' (1/60 of a 1 degree angle is referred to as a 1-angle division). That is, no matter what size or outline of the object, as long as the viewing angle of the observer is less than 1', the normal vision can not distinguish the object, and the human can observe the object, mainly depending on the reflection of the object or the main body of the light source for distinguishing.
As shown in fig. 3, point a represents the position of the observer, point B and point C have a distance d, and represent the distance between two target points, where, in order to satisfy the condition that the observer can also distinguish between point B and point C at the limit viewing angle, the size of angle a is 1', and the size of angle a represents the viewing angle limit of the observer, where if the size of angle a is less than 1', the observer will not distinguish between point B and point C, and AC represents the distance between the observer a and the object C at that time, and is represented by r. The arc BDC between the points B and C is made by taking the position of the observer A as the center of a circle and r as the radius, and the arc BDC is approximately equal to the chord BC because the angle A is extremely small. In this case, if B and C represent adjacent light-emitting elements, the distance between B and C is sufficiently narrow to form a light-emitting surface.
According to the arc length formula, the arc length of the sector =2 pi r multiplied by the angle/360, and the distance of the chord BC is obtained
Thus r =10800/d can be deduced.
As shown in fig. 4, in the case of the first light-emitting unit, where d is the distance between two adjacent first light-emitting elements 12, it is desirable that the observer can distinguish the first light-emitting unit by the human eye, and the first light-emitting unit can select the specification of the first light-emitting unit according to the positions of different observers, that is, the distance between the adjacent first light-emitting elements 12 of the first light-emitting unit is adjusted according to the positions of different observers.
Therefore, d is the first distance, and for the first light emitting unit, the first distance is used as the distance between the adjacent first light emitting elements 12, as shown in fig. 2, where the first distance is used as the distance between the adjacent first light emitting elements 12, so that it can be ensured that the light emitting surface formed between the adjacent first light emitting elements 12 is sufficiently narrow, and in the range where the light emitting surface is sufficiently narrow and can be distinguished at the limit visual angle of human eyes, the first package cover 11 is used as a light emitting surface, and in order to ensure the linearity of the light emission and avoid the problem of lamp shadow, the distance from the first package cover 11 to the light emitting surface formed by the first light emitting elements 12 needs to be adjusted; similarly, the principle of the second light emitting unit is the same as that of the first light emitting unit, and accordingly, since the light emitting directions of the first light emitting unit and the second light emitting unit are opposite, the distance from the second package cover 15 to the light emitting surface formed by the second light emitting element 14 needs to be adjusted accordingly.
In an embodiment, for a narrow light emitting surface, for example, as shown in fig. 1, where the width of the light emitting surface of the first light emitting area 1 is about 5.5 mm, in order to ensure that different light emitting surface design requirements are met, the light emitting surface inside the light emitting surface is sufficiently narrow (meeting the limit viewing angle that a person can observe), so that when the light emitting surface is narrow, light can be transmitted and can be distinguished by the person.
According to the above description, considering that the light emitting angle of the LED lamp is θ, the pitch of the light emitting elements is d, which is the first distance, so tan θ/2=d/h, it is obtained that the distance from the light emitting surface formed by the first light emitting element to the first light transmitting area of the first package cover 11 is h (which is the second distance), and correspondingly, the distance from the light emitting surface formed by the second light emitting element to the first light transmitting area of the second package cover is also h (the second distance), where it should be noted that the light emitting angle of a general LED lamp is about 120 °, and the distance from the package cover to the light emitting surface is easily obtained, which is the second distance. Thereby eliminating the light shadow problem of the adjacent light-emitting elements. When the light emitting surface is narrow enough, the packaging cover is used as a light emitting surface, and the size of the light emitting surface can be adjusted according to requirements.
The package cover comprises a first light-transmitting area and a first light-shielding area, wherein the first light-transmitting area is configured to transmit light emitted by the light-emitting element; wherein the first light transmissive region width is configured to fit the first distance.
Taking the first light emitting element as an example, it is determined through the above description that the distance between adjacent first light emitting elements is a first distance, at this time, the light emitting surface formed by the adjacent first light emitting elements is narrow enough, and at the same time, it can be satisfied that an observer distinguishes or distinguishes the adjacent first light emitting elements at the minimum viewing angle, and when the light emitting surface is narrow enough, the emitted light is to be transmitted through the first light transmitting area to form a light emitting surface, then the width of the first light emitting area can be adjusted according to the required width of the light emitting surface, and here, the width of the first light transmitting area is adapted to the first distance, and the linearity of the light emitted by the first light transmitting area can also be ensured.
As shown in fig. 2, the first light-emitting area includes a first package cover 11, a first light-emitting element 12, a first package bottom case 13, a second light-emitting element 14, and a second package cover 15, which are sequentially disposed along a first direction; the first light emitting device 12 is covered in the first package cover 11, and the second light emitting device 14 is covered in the second package cover 15. Wherein the first direction is an X-axis direction in fig. 2, wherein, according to the aforementioned distance between two adjacent light emitting elements being d, the distance from the light emitting surface to the light emitting surface, that is, the distance from the first light emitting element 12 to the first package cover 11 (the distance from the second light emitting element 14 to the second package cover 15) is h, taking the first light emitting unit as an example, wherein the first light emitting element can be selected as an LED lamp, the adjacent first light emitting elements 12 are connected to a PCB, the same LED lamp is disposed at a position where the cover setting area of one LED lamp is adjacent, and since the irradiation area of the LED lamp is a circular surface, in combination with the first light emitting area 1 shown in fig. 1 and fig. 2, in fig. 1, since the first light emitting area 1 is a serpentine light emitting surface forming a snowflake shape, the PCB provided with the first light emitting element 12 is also adapted to be a serpentine shape, and the LED lamps are disposed at equal intervals (the serpentine interval size is the first distance) along the PCB.

In addition, in some embodiments, the fixing member 17, the first packing bottom case 13, and the packing positioning columns are fastened by the anti-drop string 19.
