Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings.

First preferred embodiment:

as shown in fig. 2, fig. 2 is a sectional view of a side view in an installed state. The luminaire comprises a housing 1, the housing 1 having a top plate 11 and a first side plate 12 and a second side plate 13. The case 1 includes a light outlet 14, and a light outlet plate 2 is disposed at the light outlet 14. For convenience of description, the side of the lamp at the light outlet 14 is the front side, and the accommodating space of the case 1 is the rear side relative to the light outlet 14.

The lamp further comprises a light-emitting component 3, wherein the light-emitting component 3 is arranged on the box body 1, specifically, is arranged on one side of the light outlet 14 on the box body 1, the main light-emitting direction of the light-emitting component 3 is opposite to one side of the light outlet 14, and the projection of the light-emitting component 3 on the plane of the light outlet 14 is positioned outside the light outlet 14. The light emitting module 3 irradiates light to the rear side of the case 1, and the coverage of the directly emitted light on the plane of the light outlet 14 is located outside the light outlet plate 2.

The lamp further comprises a reflecting surface 121, and the reflecting surface 121 is located on the main light-emitting path of the light-emitting component 3, that is, at a rear side position inside the box 11. The reflective surface 121 is disposed opposite to the light-emitting plate 2, and the opposite means that the reflective surfaces are located opposite to each other or at two positions, front and rear, in one direction. In the present embodiment, the light outlet 14 is located at the front side of the case 1, the light reflecting surface 121 is located at the rear side of the case 1, and the projection of the light reflecting surface 121 on the plane of the light outlet 14 is located in the light outlet 14.

In the present embodiment, the main light emitting direction of the light emitting module 3 is inclined to the plane of the light emitting port 14, and the light emitted from the light emitting module 3 is emitted to the light emitting plate 2 through the light reflecting surface 121. The light emitting component 3 is located at one side of the light outlet 14, and irradiates light from the side facing away from the light outlet 14, and most of the inclined light beams irradiate on the reflecting surface 121 and are reflected to the light outlet 14 plate through the reflecting surface 121. And at least part of light reaches the inner wall of the box body 1 after multiple reflection, the light is reduced after multiple reflection, and compared with the light beams mainly reflected, the light has lower brightness, so that the user can not directly observe the internal structure of the box body 1. When the light emitting plate 2 is set to be blue with atmosphere from the view angle of the user, the user can see the more profound blue sky effect due to the weakening of the reflection problem inside the box 1.

In the present embodiment, the included angle β formed by the main light emitting direction of the light emitting component 3 inclined to the plane of the light emitting port 14 is 15 ° < β >45 °. At this angle, it is ensured that most of the light emitted by the light emitting assembly 3 is emitted onto the light reflecting surface 121 and is reflected to the light emitting plate 2.

In this embodiment, the reflective surface 121 has at least one concave surface 123 and one convex surface 122 opposite to the light outlet 14. The concave surface 123 and the convex surface 122 together form a wave shape, and the wave-shaped curved surface can disperse and diffuse the light beam obliquely emitted by the light emitting assembly 3 through reflection and refraction, thereby realizing a more uniform lighting effect. The conventional planar light source may cause a problem that the brightness of the illumination center is high and the brightness of the edge is low, and the problem can be improved by combining the oblique light beam and the wavy curved surface, so that the illumination effect is more uniform and soft.

In the schematic diagram of fig. 2, the reflection path of the light beam on the convex surface 122 is shown. Convex surface 122 is located on the side of proximal light emitting component 3. The light emitted by the light emitting element 3 is partially irradiated onto the convex surface 122, and the portion of the convex surface 122 close to the light emitting element 3 is a portion closer to the light outlet 14, that is, a portion lower than the convex surface 122. When the light beam irradiates the portion, the incident angle is small, and the reflected light beam is emitted from the area of the light outlet 14 near the light emitting element 3 side. As the incident angle increases gradually as the light beam approaches the farther portion from the light exit opening 14, i.e., the portion of the convex surface 122 that is higher, the reflected light beam is emitted from the area of the light exit opening 14 near the light emitting element 3 to the area of the light exit opening 14 far from the light emitting element 3.

In the schematic diagram of fig. 3, the reflection path of the light beam at the concave surface 123 is shown. Concave surface 123 is remote from the side of proximal light emitting assembly 3. The light emitted from the light emitting element 3 is partially irradiated to a portion of the concave surface 123 lower than the light outlet 14. When the light beam irradiates the portion, the incident angle is large, and the reflected light beam is emitted from the region of the light outlet 14 on the side away from the light emitting element 3. When the light beam gradually gets farther from the portion higher than the light exit opening 14, the incident angle gradually decreases, and the reflected light beam gradually exits from the region of the light exit opening 14 on the side away from the light emitting element 3 toward the region of the light exit opening 14 on the side close to the light emitting element 3.

The specific structure of the reflecting surface 121 is not limited, and in this embodiment, a convex surface 122 and a concave surface 123 of the reflecting surface 121 may be formed on the top plate 11, or may be separate components disposed on the top plate 11, and may be fixed on the top plate 11 or the side plate through a connecting member. The shape may be convex 122 and concave 123. The concave surface 123 and the reflective film are attached to the concave surface 123 to form a reflective effect. Alternatively, reflective surface 121 is formed by brushing reflective paint, lacquer, or the like on top of convex surface 122, concave surface 123. Alternatively, the reflective surface 121 is formed by providing a mirror surface on the convex surface 122 and the concave surface. As another alternative, the light reflecting surface 121 may be polished by the top plate 11 itself to form the convex surface 122 and the concave surface 123.

In this embodiment, the light emitting device further includes a mounting portion 15 provided on the case 1, the mounting portion 15 being located on the light outlet 14 side, and the light emitting element 3 being assembled and connected to the mounting portion 15. Specifically, in order to tilt the light beam of the light emitting element 3 onto the light reflecting surface 121.

Specifically, the polarizing structure 31 is a polarizing lens, and the polarizing lens itself has a condensing function, and can condense the light emitted by the light emitting component 3 through the polarizing lens, and further deflect the light emitting direction based on the condensing, so that the illumination range emitted by the lens can be collected on the reflecting surface 121, and the light of most of the light emitting component 3 is directed to the reflecting surface 121, and is reflected by the reflecting surface 121 to the light emitting plate 2.

As an alternative embodiment, the mounting reference surface of the mounting portion 15 is inclined to the plane of the light outlet 14. For example, in fig. 1, the light emitting device 3 is disposed obliquely, and the light beam can be directly irradiated onto the light reflecting surface 121 at the position of the mounting portion 15 in fig. 2, without adding a polarizing lens. In this embodiment, a condensing lens is added to the light emitting path of the light emitting module 3 to better concentrate the light beam on the reflecting surface 121, so that a very small part of the light beam is irradiated to other parts of the case 1 as much as possible.
