Description

Technical Field

[0001] The utility model relates to the technical field of floor lamps, in particular to a floor lamp which simulates sunlight. Background Art

[0002] Floor lamps are usually divided into top-lighting floor lamps and direct-lighting floor lamps. They are usually placed in living rooms and rest areas and used in conjunction with sofas and coffee tables to meet the needs of local lighting in the room and embellishing the home environment. Floor lamps that simulate sunlight are currently a popular trend.

[0003] At present, in the prior art, a Chinese patent with announcement number CN217441449U discloses a lamp that simulates sunlight. The device can simplify the manufacturing process and facilitate the heat dissipation of the light source component through the design of the specific structure of the light source component, thereby extending its service life, and can ensure the lighting effect and improve the user experience. However, in actual use, the device does not have the visual effect of presenting a blue skylight on the luminous surface of the lamp. In view of this, we propose a floor lamp that simulates sunlight. Utility Model Content

[0004] The main purpose of the utility model is to provide a floor lamp simulating sunlight, which can solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the utility model proposes a floor lamp for simulating sunlight, comprising a base, a lamp pole is fixedly connected to the top of the base, a lamp holder assembly is fixedly connected to one end of the lamp pole away from the base, and the lamp holder assembly comprises:

[0006] The shell has a solar light illumination module disposed inside the shell, the solar light illumination module includes an independent cavity reflector cup, the independent cavity reflector cup has LED light emitting diodes arranged in a matrix, and a matrix lens corresponding to the LED light emitting diodes is fixedly connected below the independent cavity reflector cup to form a rectangular solar spot with clear boundaries.

[0007] A floodlighting module is also provided inside the shell, and the floodlighting module includes a lower floodlighting module and an upper floodlighting module. The front end of the solar light illumination module is fixed to the end of the shell away from the lamp pole; the rear end of the solar light illumination module is connected to one end of the lower floodlighting module; the two ends of the upper floodlighting module are respectively connected to the front end of the solar light illumination module and the other end of the lower floodlighting module. When the solar lamp is working, the solar light illumination module and the lower floodlighting module form an irradiation area 1 and an irradiation area 2 respectively. The light irradiated by the irradiation area 1 is the light emitting surface of the solar light, and the light irradiated by the irradiation area 1 will form a light spot with an inclined angle, thereby simulating the strong light of the sun and forming a visual sense of the blue sky.

[0008] Preferably, a heat sink is provided on the lower floodlighting module.

[0009] Preferably, one end of the matrix lens away from the independent cavity reflector cup is fixedly connected to a Rayleigh scattering plate. Rayleigh scattering is an optical phenomenon, a type of scattering, also known as "molecular scattering". Rayleigh scattering is formed by light rays that are approximately parallel to the light penetrating into the Rayleigh scattering plate. The blue light has a short wavelength and is scattered, making the Rayleigh scattering plate appear blue. The effect of Rayleigh scattering can present colors such as the sky, sunset, and sea water, so that people can enjoy the mood improvement brought by different sunlight anytime and anywhere, and can then be used in the medical field to relieve patients with long-term depression by simulating sunlight of different colors through floor lamps.

[0010] Preferably, the distance between the LED and the matrix lens is less than the focal length of the lens, so that the light path is close to parallel light, but not parallel light. The size of the sun spot is determined by adjusting the distance between the LED and the matrix lens. The smaller the spot, the closer the distance needs to be to the focal length.

[0011] Preferably, a PCB substrate is fixedly connected above the independent cavity reflective cup, and the LED light emitting diode is fixedly connected below the PCB substrate.

[0012] Preferably, a control button is provided on the lamp pole.

[0013] Preferably, the inner surface of the independent cavity reflective cup is a light absorbing surface.

[0014] Preferably, the inner surface of the independent cavity reflective cup is a black reflective surface, especially a black reflective surface, thereby avoiding stray light and making the boundary line of the sun spot clearer.

[0015] Preferably, rollers are provided under the base, and the floor lamp can be conveniently moved to a desired position via the rollers.

[0016] The utility model provides a floor lamp simulating sunlight, which has the following beneficial effects:

[0017] (1) The floor lamp simulating sunlight forms a rectangular sunlight spot with clear boundaries by setting a sunlight lighting module, and forms a light spot with an inclined angle through the light irradiated from the irradiation area, thereby simulating the strong light of sunlight.

[0018] (2) The floor lamp simulating sunlight is equipped with a floodlighting module and a Rayleigh scattering plate, and the light intensity of the illuminated surface of the human body is increased to more than 10,000 lx, forming an effect of a light spot with a boundary formed by sunlight passing through a skylight. At the same time, the light-emitting surface of the lamp will present a feeling of blue sky, so that users can enjoy the comfortable feeling of bathing in the sun under the blue sky indoors even in rainy weather.

The light irradiated by the irradiation area 1 5 is the light emitting surface of the sun lamp, and the light irradiated by the irradiation area 1 5 will form a light spot with an inclined angle, thereby simulating the strong light of the sun.
