[0023] The following will be combined with the accompanying drawings of the present invention to clearly and completely describe the technical solutions in multiple embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Example 1

[0025] This embodiment provides an illumination device, including: a fixing bar 1 , a receiving cavity 2 , and a light-emitting unit 3 .

[0026] The fixing bar 1 is provided with a plurality of accommodating cavities 2, and the accommodating cavities 2 are used to accommodate and place the light emitting units 3, and the accommodating cavities 2 correspond to the light emitting units 3 one by one. The accommodating cavities 2 may be grooves, which is not limited.

[0027] The light emitting unit 3 includes a light source 4 , a light guide plate 5 and a lens 6 . The light guide plate 5 is located between the light source 4 and the lens 6 . The light beam emitted from the light source 4 to the light guide plate 5 is emitted through the lens 6 .

[0028] In this embodiment, the light beam emitted by the light source 4 to the light guide plate 5 is emitted through the lens 6, and the light transmission performance is improved, thereby alleviating the light discomfort problem currently caused by people using lamps.
