An optical lens is detachably provided on the housing. The optical lens is provided with a plurality of different mirror surfaces, and the plurality of optical lenses can be replaced by the user to display a variety of different nebulae.

A reflected light projection device is provided, comprising a projection light source assembly, a light source fixing plate for fixing the projection light source assembly, a rotatable reflector cup, a dust-proof light-transmitting sheet, and a motor driving the reflector cup to rotate. The dust-proof light-transmitting sheet, the reflector cup, the light source fixing plate, and the projection light source assembly are sequentially stacked and arranged on the motor, and the projection light source assembly, the light source fixing plate, and the reflector cup are respectively provided with a first opening, a second opening, and a third opening through which the motor passes, and a light emitted by the projection light source assembly directly irradiates the reflector cup that rotates under a drive of the motor, and the light is reflected by the reflector cup and then projected to a surface of an external medium through the dust-proof light-transmitting sheet.

An accessory mount mountable to a roof of a vehicle. The accessory mount has a horizontal mounting surface spaced from and above emergency warning lights. Accessories, such as spotlights, may be mounted on the horizontal mounting surfaces. The accessory mount provides a platform above the emergency warning lights allowing unobstructed view of the emergency warning lights without any possible of obstruction by the accessory mounted on the horizontal mounting surface.

A projection apparatus comprises a housing with a projection opening, a light source component, a reflective bowl and a driving motor in the housing, and a transparent cover is mounted on the housing and protrudes upwardly out of the projection opening. The light emitted by the light source component is illuminated on the reflective surface, and then the light passes through the transparent cover after being reflected. The light source component, the reflective bowl and the transparent cover can project to produce a cloud effect.

A reflective dynamic projector includes a light projection device. The light projection device includes a reflective element with a reflective surface, a plurality of first light sources, and a first driving unit. There are bump textures arranged on the reflective surface which make the reflective surface to be a diffuse reflection surface. The reflective surface surrounds the plurality of first light sources and each of the plurality of first light sources is arranged towards the reflective surface; or an outer surface of the reflective element is the reflective surface, the plurality of first light sources surrounds the reflective element, and each of the plurality of first light sources is arranged towards the reflective surface. The first driving unit is connected with the reflective element or the plurality of first light sources and drives the reflective element or the plurality of first light sources to rotate.

A lamp system applied to a vehicle according to the present disclosure is provided with any one of a reflector, an optical member, a digital micromirror display (DMD), a shield, or a shield optical module, and combined with a rotation light source device for generating light of a specific LED turned on at a synchronized rotation position of one or more LED chips of first to Nth LED chips (N is an integer of 2 or more) per one rotation while being rotated by a current application of a signal transmitter receiving a lamp turn-on signal of the vehicle, thereby generating various lighting patterns even while eliminating all problems of increasing the layout/decreasing the light amount/increasing the amount of property changed, lowering the reflection efficiency/transmission efficiency, and losing the optical efficiency with the circular LED array.

A projection apparatus comprises a housing with a projection opening, a light source component, a reflective bowl and a driving motor in the housing, and a transparent cover is mounted on the housing and protrudes upwardly out of the projection opening. The light emitted by the light source component is illuminated on the reflective surface, and then the light passes through the transparent cover after being reflected. The light source component, the reflective bowl and the transparent cover can project to produce a cloud effect.

A lighting system for use with evacuation systems for aircraft during emergency situations. The lighting system has a chasing or running light rhythm that provides the image of lights moving down the system to help provide clarity to the evacuees about the direction of descent.

An aroma diffuser equipped with an aurora-like situation to release fragrance, and an illuminator of a light-emitting device is used to radiate a light source to a rotating aurora reflector to reflect or diffuse or refract to produce light similar to the aurora effect. The rotating aurora reflector can rotatably reflect or diffusely reflect the radiation source of the illuminator to produce the constant changes of the aurora, and constantly change the diffuse light spot or arc-shaped ray arc. The aurora colors provided by the light-emitting device, such as green, red, or mixed colors, are reflected in a tubular light-transmitting lampshade and its outer light-transmitting shell to produce aurora scene lighting decoration or lighting effects to match the aforementioned aromatic scent atmosphere.
