Gear, to reduce the probability that light is directed to user's eyes.
The utility model is further arranged to：The blocking portion is recessed downwards to be formed by mounting shell.
By using above-mentioned technical proposal, mounting shell uses duroplasts, passes through the circumferential material by mounting shell around light-transmitting opening
Recess forms blocking portion to material downwards.
The utility model is further arranged to：The blocking portion is arc-shaped.
By using above-mentioned technical proposal, the blocking portion of arc, aesthetics is high, when user contacts blocking portion, reduces
The probability that blocking portion scratches user.
The utility model is further arranged to：The mounting shell is arc-shaped away from the remote side of support element, and arc opening
Direction is directed away from the side of support element.
By using above-mentioned technical proposal, mounting shell is arc-shaped away from the remote side of support element, increases aesthetics, user
Free Region on desktop increases, to reduce since desktop superjacent air space is small, caused by the probability that constrains of user.
The utility model is further arranged to：The mounting shell both ends in the horizontal direction on section semicircular in shape set
Set, the mounting shell vertically on the chamfered setting in section upper end.
By using above-mentioned technical proposal, the aesthetics of desk lamp is increased, desk lamp is whole in use, reduces and scratches
The probability of user.
The utility model has the following advantages：
1, arc-shaped away from the remote side of support element due to light-transmitting opening, so the intensity of the light suffered by user's eyes is equal
It is even, to reduce the impaired probability of user's eyes；
2, for user when writing, the hand of user or Pen Association form shade on the table, since light-transmitting opening is away from support element
Remote side is arc-shaped, equally reduces the area in desktop top shadow region；
3, light-transmitting opening is arc-shaped away from the close side of support element, and desk lamp forms the arc extended in the side far from user
Irradiation area increase actual use scope under the premise of saving material；
4, by main irradiated region, the primary field domain of arc is formed on the table, it is further to increase by enhancement region
The range of exposures of primary field；
5, by blocking portion, stopped between user and luminescent screen by blocking portion, to reduce light direct projection
To the probability of user's eyes.

Specific implementation mode
The utility model is described further with reference to attached drawing.
A kind of desk lamp, as shown in Figure 1：Including mounting shell 1,1 side of mounting shell is provided with support element 2, is opened up on mounting shell 1
There is light-transmitting opening 3, the luminescent screen 4 coordinated with light-transmitting opening 3 is provided in mounting shell 1.Support element 2 be supporting rod, by supporting rod come
Mounting shell 1 is supported, in use, supporting rod is far from user.Under optimal service condition, luminescent screen 4 is in the horizontal direction
Extend.
Light-transmitting opening 3 is arc-shaped away from the remote side of support element 2, and arc opening direction is directed away from the side of support element 2.Thoroughly
Optical port 3 is arc-shaped away from the close side of support element 2, and arc opening direction is directed away from the side of support element 2.The width of light-transmitting opening 3
Degree is 20mm-60mm, and the present embodiment takes 40mm.The light of luminescent screen 4 is aimed downwardly by light-transmitting opening 3, on the table
Form the primary field domain of arc.
The radius of arc of the light-transmitting opening 3 away from the remote side of support element 2 is optimal to take between 300mm-500mm
418mm.The radius of arc of the light-transmitting opening 3 away from the remote side of support element 2 is optimal to take 458mm between 340-540.
1 lower section of mounting shell is provided with the blocking portion 5 for stopping 4 light of luminescent screen.Blocking portion 5 is downward by mounting shell 1
Recess is formed.Blocking portion 5 is arc-shaped.In fabrication and installation shell 1, by by mounting shell 1 around light-transmitting opening 3 circumferential material to
Lower recess forms blocking portion 5.The material of mounting shell 1 takes duroplasts.
Use distance of the luminescent screen 4 away from desktop is optimal to use 450mm in 400mm-600mm.In actual use,
Height of the eyes of user away from desktop is about 200mm.Eye distance desk lamp plan range of the luminescent screen 4 away from user be
300mm-400mm, it is optimal to use 337mm.Stopped between user and luminescent screen 4 by blocking portion 5, to reduce light
