The housing 1 is for mounting on a preset mounting surface of a preset mounting surface.

The illumination assembly 2 includes a device body 21, a light source assembly 22, and an optical assembly 23. The device body 21 is located in the housing 1, the light source assembly 22 and the optical assembly 23 are both arranged in the device body 21, the light emergent surface of the light source assembly 22 faces the preset mounting surface, the optical assembly 23 is located on the light emergent side of the light source assembly 22 and is used for receiving light rays emitted by the light source assembly 22 and refracting the light rays, so that the refracted light rays are projected onto the preset mounting surface through the housing 1 and are reflected by the preset mounting surface in a diffuse manner and then are emitted in a direction deviating from the preset mounting surface.

In particular, the outer cover 1 may be made of a material having light-guiding and light-transmitting properties, such as acryl. The housing 1 is used for being mounted on a preset mounting surface of a preset mounting surface, so that the lighting device is integrally mounted on the preset mounting surface. The preset installation surface may be, for example, a wall or a ceiling of a room.

The lighting process or principle of the lighting assembly 2 will be described by taking a preset installation surface as an indoor ceiling as an example:

The light source assembly 22 and the optical assembly 23 of the lighting assembly 2 are arranged in the device body 21, the light emitting surface of the light source assembly 22 can face towards the ceiling, namely, face away from the indoor ground, the optical assembly 23 is positioned on the light emitting surface of the light source assembly 22, so that light rays emitted by the light source assembly 22 are refracted by the optical assembly 23 and then are emitted out through the outer cover 1, and at the moment, the light rays refracted by the optical assembly 23 are emitted out through the outer cover 1 and then are directly projected onto the ceiling and are emitted downwards after being diffusely reflected by the ceiling, so that the indoor lighting effect is realized. Meanwhile, the light after diffuse reflection by the ceiling is softer, more uniform and lower in glare, so that dazzling and dizziness feeling can not be generated, and the use experience of a user can be effectively improved.

Further, it should be noted that, in this embodiment, the light is irradiated onto the ceiling and emitted towards the ground after being diffusely reflected by the ceiling, at this time, the light is transmitted to the ceiling so that the whole ceiling can be illuminated, at this time, the brightness of the whole ceiling illuminated is close to the brightness of the lighting device, so that no obvious bright-dark distinction exists between the ceiling and the lighting device, and therefore, the effect of no-light or no-light can be achieved to a certain extent, the overall look and feel and anti-dizziness feel of the lighting device are improved, and the use experience of the user can be effectively improved.

Specifically, when the light refracted by the optical component 23 is emitted through the housing 1, the light passes through the housing 1 and simultaneously makes the whole housing 1 be lighted, and at this time, the brightness of the whole illuminated ceiling is relatively close to the brightness of the whole housing 1, so that the effect of hiding the housing 1 from view can be achieved, and the effect of visually non-light and non-boundary lighting can be achieved, so that the user does not feel the lighting surface of the lighting device obviously, and the problem that visual fatigue is easily caused because the user can see the lighting surface of the lighting device obviously and the user's sight line is focused on the lighting surface of the lighting device is avoided. In addition, when the lighting device works, the outer cover 1 can be integrally conducted, so that the brightness of the outer cover 1 can be calculated and adjusted through an algorithm, the brightness of the outer cover 1 can be infinitely close to the brightness of the illuminated surface of the preset mounting surface, the visual effects of no light sensation and no light are further improved, and the use experience of a user is further improved.

Or in other implementations, the device body 21 may be made of plastic or the like to reduce overall weight and material cost.

In addition, in this embodiment, the diffuse reflection of light can be performed by adopting the preset installation surface such as the ceiling to realize the soft light effect, so that the problem that the cost is high due to the fact that the diffuse reflection element is additionally arranged in the housing 1 to perform the diffuse reflection of light occupies the internal space of the housing 1, the structure is complex, and the number of parts is large can be avoided. In addition, the method can also be combined with an algorithm to realize the rhythmic lighting effect, and simulate better and more natural sunrise and sunset effects.

Meanwhile, the light after diffuse reflection by the ceiling is softer, more uniform and lower in glare, so that dazzling and dizziness feeling can not be generated, and the use experience of a user can be effectively improved.
