Referring to fig. 1 to 6, a first embodiment of the present invention is:

an eye-protecting lamp comprises a base 10, a first lighting assembly 20 and a second lighting assembly 30;

the lamp housing comprises a fixed plate 23 and two connecting plates 24, the fixed plate 23 is connected with the other end of the first rotating rod 22, the two connecting plates 24 are respectively arranged at two sides of the fixed plate 23, the two connecting plates 24 are respectively arranged towards the base 10 in an inclined mode, and meanwhile the projection of the lamp housing along the axial direction of the first rotating rod 22 is in an arch shape;

the second lighting assembly 30 includes two second rotating rods 31, two lamp tubes 32 and two fixing seats, and the second rotating rods 31 are telescopically arranged;

the fixing seats comprise a first fixing seat 34, a second fixing seat 35 and a third fixing seat 36 which are coaxially arranged and sequentially sleeved, and the second fixing seat 35 and the third fixing seat 36 are respectively rotatably arranged around the central axis of the first fixing seat 34;

a strip-shaped lamp tube 37 is arranged on one axial side of the first fixed seat 34, the lamp tube 37 and the first fixed seat 34 are coaxially arranged, the first fixed seat 34 is used for supporting the lamp tube 37, one ends of the two second rotating rods 31 are respectively rotatably connected with two opposite side walls of the first rotating rod 22, and the other end of the second rotating rod 31 is rotatably connected with the other side of the first fixed seat 34; thus, the position of the lamp 37 can be adjusted by rotating or extending or retracting the second rotating lever 31.

In particular, when the lamp 37 moves to the position of the groove 25 on the two connecting plates 24, the light emitted therefrom is distributed to irradiate towards the lower part of each other, so as to match with the light emitted from the light source plate 26 located below the fixing plate 23, and a solid uniform light is formed below the arched lamp housing, it can be expected that when a user places a book below the lamp housing, the light is emitted towards the hand in all three directions, namely, the left and right directions, so as to reduce the shadow of the hand.

In order to fold the light beam of the lamp tube 37 and avoid the light beam from being scattered in the direction far away from the surface to be illuminated, the second fixing seat 35 is provided with the reflecting plate 38, the shape of the axial projection of the reflecting plate 38 along the second fixing seat 35 is arc-shaped, the second fixing seat 35 is rotatable, which is a natural reason, the reflecting plate 38 can rotate around the central axis of the lamp tube 37 along with the second fixing seat 35, so that the light beam emitted by the lamp tube 37 is folded at an ideal angle, and the protruding part 60 is arranged on one side of the second fixing seat 35 far away from the reflecting plate 38, so that a user can push the protruding part 60 with fingers to rotate the second fixing seat 35, and the reflecting plate 38 is more easily rotated.

In the field of lamps, in particular lamps for learning, besides the influence of the unevenness of the light or the resulting shadow on the vision of the human eye, the blue light emitted by the lamp also has an influence on the human eye,

for this purpose, the third fixing base 36 is sleeved with the lamp cylinder 32, and when the third fixing base 36 rotates, the lamp cylinder 32 also rotates. The fluorescent tube 37 is located a lamp section of thick bamboo 32, and the outer wall of a lamp section of thick bamboo 32 pastes along the circumference of self and is equipped with prevents blue light membrane 40, and the light that fluorescent tube 37 sent shines to a lamp section of thick bamboo 32 outside through preventing blue light membrane 40, and the size of a lamp section of thick bamboo 32 is set for just in time can imbed in the recess 25, and like this, a lamp section of thick bamboo 32 has also played the positioning action, and two connecting plates 24 can prevent that light from effluvizing.

Preferably, the connection plate 24 is rotatably connected to the fixing plate 23, and the connection plate 24 is movably disposed toward or away from the light source plate 26, so that the light emitting angles of the two lamps 37 can be changed while the lamp cartridges 32 are fitted into the recesses 25.

Preferably, the anti-bluing film 40 on the outer wall of the lamp cylinder 32 covers more than half of the area of the side wall of the lamp cylinder 32 in the circumferential direction of the lamp cylinder 32, and when the lamp cylinder 32 is fitted into the groove 25 of the coupling plate 24, the anti-bluing film 40 covers the portion of the lamp cylinder 32 exposed from the groove 25. Thus, the lamp cartridges 32 on both sides of the light source board 26 can emit light that filters blue light.

The above design is also advantageous in that if the anti-blue film 40 is simply provided, the luminance of light is insufficient, and the light emitted from the light source board 26 provides the basic luminance, thereby reducing blue light while ensuring the luminance.

The opening of the lamp tube 32 at the end far away from the first fixing seat 34 is provided with a light shield 33, and the light shield 33 can shield the light emitted from the opening of the lamp tube 32.

Besides the blue-proof film 40 disposed on the sidewall of the lamp tube 32, light-transmitting films 50 with different transmittances and light-transmitting films 50 with different colors can be attached along the lamp tube 32, so as to be suitable for other applications. In this embodiment, the anti-blue film 40 occupies one half of the sidewall of the barrel 32 in the circumferential direction of the barrel 32, and the other two light-transmitting films 50 having different transmittances occupy one quarter of the sidewall.

In summary, the invention provides an eye-protecting lamp which reduces the shadow area and has more uniform and soft light. Light rays emitted by the light source plate under the fixed plate in the eye-protecting lamp and light rays emitted by the lamp tubes which can be placed in the grooves of the connecting plate form three-dimensional uniform light rays, and the generation of shadows can be effectively reduced by illumination at a plurality of angles; meanwhile, the position of the fixed seat can be changed by rotating the second rotating piece, so that the position of the lamp tube is changed, and the lamp tube is suitable for illumination at different angles; in addition, the light transmitting film for preventing the blue light film and other different light transmittances is arranged on the lamp barrel, the type of the light transmitting film on the outer wall of one side, close to the base, of the lamp barrel can be changed by rotating the lamp barrel, light rays for filtering the blue light can be provided, light rays for protecting eyes more softly can be provided, and more combination types can be provided for the light rays emitted by the light source plate.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent changes made by using the contents of the present specification and the drawings, or applied directly or indirectly to the related technical fields, are included in the scope of the present invention.
