Therefore, these and other directional terms should not be construed as limiting terms.

"outside" in this application refers to the exterior of the light emitting device being deep and "inside" refers to the interior of the light emitting device. The upper part of fig. 1-9 is "outer" and the lower part is "inner".

The first embodiment is as follows:

fig. 1 is a schematic structural view of a deep-feeling light-emitting device according to an embodiment.

Profound sensation light emitting equipment, including the lamp shade, lamp body 1, decorations circle 2 and LED3, the lamp shade contains outer lamp shade 4 and interior lamp shade 5, outer lamp shade 4 and lamp body 1 lock, decorations circle 2 and LED3 are installed in the cavity of outer lamp shade 4 and lamp body 1, be equipped with spectral film 51 on the medial surface of interior lamp shade 5, the lateral surface on the decorations circle 2 is reflection of light face 21, relative interval arrangement between spectral film 51 and the reflection of light face 21, LED3 is located the next door of decorations circle 2, LED3 jets out light towards spectral film 51, a small part of light sees through spectral film 51 and interior lamp shade 5, most light is reflected by spectral film 51, shoot reflection of light face 21, spectral film 51 and reflection of light face 21 are like upper alternate reflection of light.

Specifically, the outer lampshade 4 and the inner lampshade 5 are transparent shells, the inner lampshade 5 extends along the length direction of the outer lampshade 4, the inner lampshade 5 and the decorative ring 2 are arranged in parallel, and the lengths of the inner lampshade and the decorative ring are basically equal.

A group of LEDs 3 is installed at one end of the bezel 2 and arranged toward the inner lampshade 5, an auxiliary lampshade 7 is arranged right in front of the LED3, the auxiliary lampshade 7 arranges the point light source of the LED3 into a surface light source, and the auxiliary lampshade 7 can be in a strip shape or a ring shape.

The light splitting film 51 in this embodiment is a neutral light intensity light splitting film, and has the same transmittance and reflectance ratio for each wavelength in the visible light region, and the reflected light and the transmitted light have the same color as the incident light. And a small part of the light passes through the spectroscopic film 51 and the inner lamp housing 5, and most of the light is reflected by the spectroscopic film 51. The light splitting module 51 is almost transparent when viewed from the outside to the inside, and looks like a mirror when viewed from the inside to the outside, most of the light rays are reflected specularly, and a small part of the light rays are refracted and transmitted. Therefore, the spectroscopic film 51 can reflect most of the light of the LED3 to the light reflection surface 21.

Alternatively, the light splitting film 51 may also be other types of light splitting films to generate different light effects.

The reflective surface 21 may be an aluminum-plated mirror surface, and the reflective surface 21 reflects the light onto the spectroscopic film 51, so as to reflect alternately.

Alternatively, the reflective surface 21 may also be used in other ways to achieve a specular reflection effect.

As shown in fig. 1, the LED3 in the first embodiment is arranged on the right side of the bezel 2, and light rays are continuously reflected from right to left and finally almost totally emitted from the inner lamp cover 5. Since the light-splitting film 51 and the light-reflecting surface 21 form two opposite mirror surfaces, a profound visual effect is achieved by multiple times of alternate mirror reflection. In the first embodiment, only one group of LEDs, namely one light source, is needed, so that the cost is greatly saved; compared with the existing scheme of adopting the OLED, the LED is easy to produce in quantity and is low in price.

Wherein, one LED or more than two LEDs in one group of LEDs can be adopted.

Fig. 10 is a view showing the effect of depth of field of the deep-feeling light-emitting device according to the first embodiment. Where D is the distance between the reflective surface 21 and the spectroscopic film 51. After the light is reflected by the primary splitting film 51 and the reflecting surface 21, the depth of field of the mirror image E observed from the eyepoint is 2D; after the reflection of the second spectroscopic film 51 and the reflective surface 21, the depth of field of the mirror image F observed from the eyepoint is 4D; by analogy, the depth of field observed after each additional reflection is a multiple of 2D, thereby producing profound lighting effects.

Preferably, D is 30mm, and the profound feeling light emitting apparatus in the present embodiment requires a very small structural space, so that a profound visual effect can be achieved.

Example two:

fig. 2-3 are schematic structural views of the deep-feeling light-emitting device in the second embodiment.

The inner side surface of the decorative ring 2 is provided with a driving unit 6, and the driving unit 6 is used for driving the decorative ring to move towards or away from the inner lampshade 5.

Further, the inner lamp shade 5 is parallel to the decorative ring 2, the driving unit 6 comprises two lifting motors 61 which are respectively installed at two ends of the decorative ring 2, the two lifting motors 61 are synchronously telescopic, and the decorative ring 2 is driven to move towards or away from the inner lamp shade 5 when the strokes are the same.

As shown in fig. 2, in the initial state, the distance between the spectroscopic film 51 and the light reflecting surface 21 is D1.

As shown in fig. 3, when the lift motor 61 is extended toward the inner lamp cover 5, the bezel 2 is pushed out toward the inner lamp cover 5, D1 becomes smaller, and as D1 becomes smaller, the number of times the light is reflected becomes larger, and the number of imaging layers increases. If the lift motor 61 is retracted, D1 becomes larger, the number of times the light is reflected is reduced, and the number of imaging layers is reduced. In the second embodiment, the lifting motor 61 can be controlled to gradually extend or retract towards the inner lampshade 5, so that a profound effect with a changing effect is realized, and a cool visual experience is brought.

Further, the change of the lifting strokes of the two lifting motors 61 with time can be linear or stepped, and the change corresponding to the profound effect is gradual and stepped. The lifting stroke of the lifting motor 61 as a function of time can be set arbitrarily to obtain the profound effect of the various changing effects.

Alternatively, the driving unit 6 may also adopt other driving modes, such as: electromagnet and connecting rod. When the electromagnet is energized, the linkage is pulled, causing D1 to become smaller. Or the motor drives the gear, and the gear drives the decorative ring 2 to extend up and down.

Example three:

fig. 4-5 are schematic structural views of the deep-feeling light-emitting device in the third embodiment.

The difference from the second embodiment is that: in the third embodiment, only one lifting motor 61 is provided, the lifting motor 61 is installed at one end of the decorative ring 2, the other end of the decorative ring 2 is fixedly connected through a rotating shaft 62, and the lifting motor 61 drives one end of the decorative ring 2 to rotate around the rotating shaft 62.

As shown in fig. 4, in the initial state, the inner lamp cover 5 and the bezel 2 are parallel to each other.

As shown in fig. 5, the lift motor 61 is raised, so that the bezel 2 at the left end is moved toward the inner lamp housing 5, and the right end of the bezel 2 is rotated about the rotary shaft 62.

In fig. 5, D1 at the rightmost end is constant all the time, from right to left, the number of reflections increases, and the distance D1 between reflections gradually decreases each time, the depth of field continuously deepens, and a deep mirror effect similar to infinite reflection is formed.

The driving unit 6 in the third embodiment can adjust not only the distance between the inner light cover 5 and the bezel 2 but also the angle between the inner light cover 5 and the bezel 2.

Alternatively, the driving unit may include two lifting motors 61, and the two lifting motors 61 do not extend or retract simultaneously, and when one lifting motor 61 extends, the other lifting motor 61 retracts; or one lift motor 61 is retracted while the other lift motor 61 is extended. D1 at one end becomes smaller and D1 at the other end becomes larger, which results in another deep mirror effect similar to infinite reflection different from the third embodiment due to the different distance of each reflection.

Example four:

as shown in fig. 6, the auxiliary lampshade 7 is strip-shaped, and the reflective surface 21 of the decorative ring 2 has no pattern. The light emitted from the LED3 passes through the auxiliary lampshade 7, and the strip-shaped auxiliary lampshade 7 as a whole is used as a surface light source, and is reflected for a plurality of times between the light splitting film 51 and the light reflecting surface 21, thereby forming a strip-shaped array effect. Where A is the primary image of the light source and B is the mirror image of the light source.

Example five:

as shown in fig. 7, the auxiliary lampshade 7 is provided with a dotted pentagram pattern, which can be realized by laser etching, decoration ring shielding and other methods after electroplating. The light emitted from the LED3 passes through the auxiliary lampshade 7, and the five-pointed star on the auxiliary lampshade 7 is reflected between the light-splitting film 51 and the reflective surface 21 for multiple times, so as to form a five-pointed star matrix effect. Where A is the primary image of the light source and B is the mirror image of the light source.

Example six:

as shown in fig. 8, the auxiliary lampshade 7 may be 2 strips, and is also formed into a strip shape when viewed from the external appearance after being reflectedArray of cellsAnd (4) lighting effect. In the sixth embodiment, the LEDs 3 include a red LED for the position light and a yellow LED for the turn signal light. The position light and the steering light share a light emitting surface. The profound feeling light-emitting device at this time can have three working modes:

in the first mode, the position lamp mode is adopted, the red light LED emits light, the yellow light LED is turned off, and the red strip-shaped lighting effect is presented.

In the second mode, the steering lamp is turned off, the red light LED is turned off, and the yellow light LED emits light to present a yellow strip-shaped lighting effect.

And thirdly, in the mixed mode, the red light LED and the yellow light LED both emit light and present the strip light effect with the interval of the red light and the yellow light. In fig. 8, a1 represents a red primary image, a2 represents a yellow primary image, and B represents a mirror image.

Example seven:

as shown in fig. 9, the auxiliary lamp cover 7 may be set to 2 rows of dot patterns, and may be implemented by laser etching, masking with a decorative ring, and the like after electroplating. The point array light effect is formed when the reflection is observed from the appearance.

The seventh embodiment also has three operation modes and also exhibits three profound effects.

In fig. 9, a1 represents a red primary image, a2 represents a yellow primary image, and B represents a mirror image.

Optionally, the auxiliary lampshade 7 may be provided with other patterns, and may be a single color light LED, or a combination of LEDs with different colors, and the color of the LED may also be white light.

The deep-feeling light-emitting device in embodiments one to seven can be applied to a vehicle body as a vehicle lamp, and can be used as an atmosphere lamp, or a turn lamp, or a position lamp, or a daytime running lamp.

Alternatively, the deep-feeling light emitting apparatus can also be applied to other fields, for example: decorative lamps for domestic or commercial use, or motorcycle lamps, etc.
