In this embodiment, the light source module 22 is exemplified by a plurality of light emitting diode elements 221. Of course, the number of the light emitting diode elements 221 can be changed according to actual needs, and the arrangement of the light emitting diode elements 221 The methods are generally symmetrical to each other. When an external power source (not shown) is electrically connected to the circuit board 222, the light-emitting φ diode elements 221 emit light. The concentrating plate 30 is disposed in the lamp cover 21 and disposed on the illuminating diode element 221. The concentrating plate 30 has a concentrating element 31, and the concentrating element 31- is disposed corresponding to the illuminating diode element 221. In the present embodiment, the concentrating plate 30 has a plurality of concentrating elements 31, and the concentrating elements 31 are respectively disposed corresponding to the illuminating diode elements 221. As shown in FIG. 2, the concentrating plate 3 of the embodiment has a plate body 32.

When the side light ray L1 emitted from the light-emitting diode element 221 enters the condensing element 31 by the wall surface 311b of the concave portion 311, the condensing element 31 reflects the light ray L1 and is emitted from the light-emitting surface 313. When the light L2 emitted from the light-emitting diode element 221 enters the light collecting element 31 from the bottom surface 311a of the concave portion 311, the bottom surface (the convex surface) 311a collects the light L2 and emits the light L2 from the light exit surface 313. Of course, the bottom surface 311a of the concave portion 311 of the concentrating element 31 may not be a convex surface. Referring to FIG. 4, the bottom surface 311a of the concave portion 311 of the concentrating element 31 has a Fresnel pattern F. Thus, the Fresnel pattern F can also collect light to turn incident light into parallel light. Of course, the Fresnel pattern F can also be disposed on the light exit surface 313 of the concentrating element 31. Referring to FIG. 2 again, the illuminating device 2 of the present embodiment further includes a diffusing plate 23 disposed in the lamp cover 21 and facing one of the light emitting surfaces 30a of the concentrating plate 30. The diffusing plate 23 may have a plurality of diffusing particles, a whitening agent, a plurality of phosphors or a microstructure, and the diffusing particles, the brightener, and the fluorescent light have a function of diffusing light. In this way, the diffusing plate 23 softens the light emitted from the light emitting surface 30a of the concentrating plate 30, so that the visual feeling of the user is more comfortable and the glare is prevented. The illuminating device 2 of the present embodiment further includes a heat dissipating fan 24 connected to the lamp cover 21. When the lighting device 2 is activated, the cooling fan 24 can promote the flow of ambient air to assist the lighting device 2 to dissipate heat, thereby ensuring the service life of the lighting device 2. With the above configuration, since the condensing element 31 of the concentrating plate 30 can condense the light emitted from the illuminating diode element 221, the brightness of the light of the illuminating diode element 221 can be improved, and the occurrence of glare can be avoided. In addition, the diffusing plate 23 can diffuse light, so that the user feels comfortable in reading, and indeed meets the needs of practical use. Referring to FIG. 5 , a lighting device 4 according to a second embodiment of the present invention includes a lamp cover 41 , a light source module 42 , a concentrating plate 43 , and a diffuser plate 44 , and further includes a Fresnel pattern. Board 45. The technical features and functions of the lampshade 41, 0·the light source module 42, the concentrating plate 43, and the diffusing plate 44 are the same as those of the lampshade 21, the light source module 22, the concentrating plate 30, and the diffuser plate 23 of the first embodiment. This content is not described here. In the present embodiment, the Fresnel pattern plate 45 is disposed between the concentrating plate 43 and the diffusion plate 44. Thereby, the Fresnel pattern 45 can uniformly emit the brightness of the light from the concentrating sheet 43. Next, please refer to FIG. 6, which is a perspective view of the light beams of the illumination devices A, B, and C.
