Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a small starlight rotation simulator. Background Art

[0002] In the prior art, there are already various styles of lamps that can meet the needs of users. Among them, starlight lamps can simulate the lighting effect of a starry sky, so that a number of light sources are irradiated in different directions to imitate the effect of starlight.

[0003] In order to meet some special usage requirements, it is necessary to add a rotation function based on the existing starlight lamp. However, currently only the lamp body with the light source can be rotated. When the lamp body rotates, each light source is "drawing circles", and the atmosphere effect that the lamp can achieve is single and monotonous. Utility Model Content

[0004] The utility model aims to provide a small starlight rotation simulator to solve the problems existing in the prior art, and can simulate the starlight irradiation effect with a rotation function, and has a small size, a large irradiation range and rich lighting forms.

[0005] In order to achieve the above purpose, the solution of the utility model is:

[0006] A small starlight rotation simulator comprises a base, and a motor, a turntable, a large reflector, a concave lens, a light source and a circuit board mounted on the base; the turntable is mounted on the output shaft of the motor and driven to rotate by the motor; a plurality of small reflectors are arranged on the turntable, and an irregular angle is formed between each small reflector and the plane of the turntable; the large reflector and the turntable are respectively arranged on both sides of the concave lens; the light source is arranged opposite to the large reflector, and its output light is reflected to the concave lens via the large reflector, and refracted to the turntable by the concave lens; the circuit board is electrically connected to the motor and the light source.

[0007] The motor is a stepping motor.

[0008] The light source is composed of a plurality of direct-illumination bulbs.

[0009] After adopting the above technical solution, the utility model has the following technical effects:

[0010] The light emitted by the light source of the utility model is reflected by the large reflector and then refracted by the concave lens to achieve diffusion, thereby increasing the illumination range of the light source and covering the entire surface of the turntable, and achieving a larger illumination range with a smaller volume; at the same time, the turntable rotates under the drive of the motor, and since the angle formed between the small reflector on the surface of the turntable and the turntable is irregular, the light will be reflected in different directions during the rotation of the turntable, forming a rotating "sky full of stars" atmosphere light effect with rich lighting forms.

[0014] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0015] refer to Figure 1 As shown, the utility model discloses a small starlight rotation simulator, comprising a base 1, and a motor 2, a turntable 3, a large reflector 4, a concave lens 5, a light source 6 and a circuit board 7 mounted on the base 1;

[0016] The turntable 3 is mounted on the output shaft 21 of the motor 2 and is driven by the motor 2 to rotate; a plurality of small reflectors 31 are arranged on the turntable 3, and an irregular angle is formed between each small reflector 31 and the plane of the turntable 3;

[0017] The large reflector 4 and the turntable 3 are respectively arranged on both sides of the concave lens 5;

[0018] The light source 6 is arranged opposite to the large reflector 4, and the light emitted by the light source 6 is reflected by the large reflector 4 to the concave lens 5, and then refracted by the concave lens 5 to the turntable 3;

[0019] The circuit board 7 is electrically connected to the motor 2 and the light source 6 to achieve switching and adjustment control.

[0020] Through the above scheme, see Figure 1The light emitted by the light source 6 of the utility model is reflected by the large reflector 4 and then refracted by the concave lens 5 to achieve diffusion, thereby increasing the illumination range of the light source 6 and covering the entire surface of the turntable 3, and achieving a larger illumination range with a smaller volume; at the same time, the turntable 3 rotates under the drive of the motor 2. Since the angle formed between the small reflector 31 on the surface of the turntable 3 and the turntable 3 is irregular, the light will be reflected in different directions during the rotation of the turntable 3, forming a rotating "sky full of stars" atmosphere light effect with rich lighting forms.

[0021] Specific embodiments of the present utility model are shown below.

[0022] The above-mentioned “irregular angle” means that the small reflectors 31 and the turntable 3 can have any angle, and the angle values ​​between the small reflectors 31 and the turntable 3 are as non-repetitive as possible, and the directions of the small reflectors 31 are as different as possible.

[0023] The motor 2 is a stepper motor, which can more accurately control the rotation angle of the motor 2 to achieve an atmosphere effect of "turning and stopping from time to time" with a sense of frustration.

[0024] The light source 6 is composed of a plurality of direct light bulbs, so that the light emitted by the light source 6 is more dispersed, and the light is more dispersed and softer after being reflected / refracted by the large reflector 4, the concave lens 5 and the small reflector 31.

[0025] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
