Between the first housing 11, the second housing 12, and the third housing 13, a plurality of cavities are formed for mounting components of different functions.

The first casing 11 has an air inlet 111 in the middle, and the air inlet 111 is a circular structure and is formed by sinking the first casing 11 to the middle and forming a through hole. At the periphery of the air inlet 11, the first housing 11 is raised upward and then goes downward at the edge, forming a main light source cavity 112 and a sub light source cavity 113. The main light source cavity 112 and the sub light source cavity 113 are separated from each other, and both have an annular structure. In the main light source cavity 112, a first light source assembly 2 is installed; in the sub-light source cavity 113, the second light source assembly 3 is installed.

As shown in fig. 4, the width of the inner side 4321 of the blade 432 is greater than the width of the outer side 4322, i.e. the width of the blade 432 decreases smoothly from the inside to the outside. Moreover, the distance between two adjacent blades 432 gradually increases from inside to outside; the purpose of this is to introduce more gas flow.

Referring back to fig. 2, the fan assembly 4 of the present embodiment further includes an air guiding plate 44 having an arc structure, and the air guiding plate 44 is disposed between the fan blade 432 and the air outlet 122. The air guide plate 44 is integrally formed with the second casing 2 and extends and protrudes downward from the second casing 2. When the motor 41 drives the fan blade 432 to rotate, the air guiding plate 44 not only can guide the airflow accelerated by the fan blade 432 to the air outlet 122, but also can prevent the airflow guided to the upper side of the air outlet 122 from forming a vortex, so that the wind speed of the air outlet 122 can be increased.

Since the air supply cavity 121 narrows to the air outlet 122 in a gradual manner, the air flow is compressed, and a high-speed air supply effect can be achieved, and the air speed of the air flow flowing downwards from the air outlet 122 is over 5m/s through tests.

In some embodiments, the first light source assembly 2 may be composed of different first light source elements 21. It is understood that the spectrum of the light generated by the first light source unit 21 is different depending on the light emitting elements 212. For example, the first light source elements 21 may be respectively provided as: a light emitting device A for emitting light containing long-wavelength blue light, a light emitting device B for emitting light that confines the long-wavelength blue light, and a light emitting device C for emitting light of low blue light. The light emitting devices are light emitting diodes; the light emitting device B emits light for limiting the long-wave blue light, that is, the proportion of the long-wave blue light in the emitted light is correspondingly limited, that is, the proportion of the long-wave blue light in the emitted light is searched.

The controller is arranged in the accommodating cavity and can drive and control the spectrum formula of the light-emitting devices A, B and C according to the set illumination modes, namely the learning work mode, the leisure mode and the sleep mode. Wherein, adopt the sleep mode of zero blue light spectrum under the sleep situation, adopt the leisure mode that has reduced long wave blue light spectrum in the leisure situation, adopt the study mode of increasing long wave blue light spectrum under study and work situation.

That is, the light emitting devices a, B and C of the present embodiment may provide light rays having the same color temperature and different physiological stimulus values, and also provide light rays having different color temperatures and different physiological stimulus values, and the color temperatures and light intensity information related to these light rays are also stored in the memory in advance. The controller can call corresponding light emitting device information according to the lighting mode, and then drive different light emitting devices. The color temperature and the light corresponding to the power of the wavelength region are provided by the controller according to the received instruction and calling the corresponding lighting mode.

The illumination modes include a learning mode, a leisure mode, and a sleep mode. The learning operation mode, the leisure mode, and the sleep mode in the illumination mode of the present embodiment are controlled and switched by the controller.

Specifically, in the learning mode of operation, the controller drives light emitting device a, light emitting device B, and light emitting device C to obtain the following spectral formula:

(1) CCT is less than or equal to 3000K: the power proportion of the short-wave blue light region is less than 5%, and the power proportion of the long-wave blue light region is more than 10%; (2) for 3000K < CCT ≦ 4000K: the power proportion of the short-wave blue light region is less than 10%, and the power proportion of the long-wave blue light region is greater than 15%; (3) for a CCT < 4000K < 5000K: the power proportion of the short-wave blue light region is less than 12%, and the power proportion of the long-wave blue light region is greater than 18%; (4) for other color temperatures: the power ratio of the short-wave blue light region is less than 15%, and the power ratio of the long-wave blue light region is greater than 22%.

The learning and working mode is an illumination mode added with a spectrum formula of long-wave blue light, under the illumination mode, the wavelength of light is controlled to be 480nm, a user can keep high sobriety degree and has a high physiological stimulus value, the physiological stimulus value of light can be adjusted according to requirements, the provided light has low blue light harm, and the retina cannot be excessively injured even if the light is used for a long time.

In the leisure mode, the controller drives light emitting device a, light emitting device B, and light emitting device C to obtain the following spectral formula:

(1) CCT is less than or equal to 2500K: the power proportion of the long-wave blue light region is less than 2 percent; (2) for 2500K < CCT ≦ 3500K: the power ratio of the long-wave blue light region is less than 5 percent; (3) for 3500K < CCT ≦ 4500K: the power proportion of the long-wave blue light region is less than 10 percent; (4) for other color temperatures: the power ratio in the long-wave blue region is < 15%.

In the sleep mode, the controller drives light emitting device a, light emitting device B, and light emitting device C to obtain the following spectral formula: the power ratio of the blue light region with the wavelength region of 420-500nm is less than 5%. In the leisure/sleep mode, the wavelength of the light is outside 480 nm.

The leisure mode is an illumination mode of a spectral formula for reducing the long-wave blue light, and under the illumination mode, the secretion of melatonin can be promoted through the color temperature and the illumination condition of the light, so that an illuminated person can have a more comfortable rest/entertainment state.

In the sleep mode, the power ratio of the blue light region with the wavelength interval of 420-500nm is controlled to be less than 5%, so that the phenomenon that the blue light spectrum energy with a larger proportion inhibits the secretion of the melatonin of the brain can be avoided, the melatonin of the brain is normally secreted, and the sleep quality of a user is improved. In addition, because the melatonin is inhibited in the learning and working mode, the melatonin of the brain is greatly secreted in the sleep mode, and the sleep mode is favorable for fast falling asleep.

The controller can select and switch to a target illumination mode in a working mode, a leisure mode and a sleep mode according to the light change or the receiving instruction of the illumination place; the controller drives the light emitting device A, the light emitting device B and the light emitting device C to adjust the CCT according to the target illumination mode; and finally, the light-emitting device A, the light-emitting device B and the light-emitting device C acquire a spectrum formula according to the target illumination mode.

That is, the thickness of the light guiding body 320 spirally decreases from the starting end 321 to the terminal end 322, and then the terminal end 322 is connected to the starting end 321, so that the light guiding body 320 has a single-turn spiral annular structure; a light emitting portion 324 is formed on the flat bottom surface of the light guide body 320. The spiral light guide body 32 can achieve higher light emitting efficiency and higher light emitting uniformity.
