Furthermore, the terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

Referring to fig. 1, the transmission area of the conventional desk lamp is centered on the light source, and the front and rear areas are completely the same, when the desk lamp is used, the lamp head of the desk lamp needs to be tilted upward to move the illumination area toward the user, so that the use space of the desk top can be ensured.

The front and rear regions mentioned above refer to a region close to the user and a region far from the user, respectively, and the concept of the front and rear direction is the same hereinafter.

The front lighting desk lamp of the embodiment of the present invention, as shown in fig. 2-7, comprises a lamp head 100;

the light emitting part 110 is obliquely disposed in the base 100, and the light emitting part 110 does not protrude from the base 100; the light emitting portion 110 that does not protrude from the base 100 makes it almost impossible for the user to look directly at the light source without the base 100 being tilted upward.

When the lamp head 100 is in a horizontal position, the included angle between the light emitting part 110 and the horizontal plane is an acute angle;

the acute angle opening direction is towards the user of the desk lamp. The light emitting part 110 is obliquely disposed to move the illumination area of the desk lamp forward, i.e. toward the user, and as will be readily understood from the drawings, the center of the illumination area after forward movement is far from the desk lamp, i.e. when the desk lamp is used, the desk lamp can be placed far from the user, so that the available space on the desk surface is larger.

Further, as shown in fig. 3, the lamp cap 100 includes a lamp cap upper shell 120 and a lamp cap lower shell 130, which are spliced together and have a hollow interior to form an accommodating cavity, and the light-emitting portion 110 is disposed in the accommodating cavity;

as shown in fig. 4, the light emitting part 110 forms an acute angle of 5 ° to 15 °, preferably 10 °, with the light exit hole 131 of the cap lower case 130. When the angle is selected to be 10 degrees, the lamp cap 100 is horizontally arranged, and the highest point of the light direct-illuminating area is below the neck of the user, so that the forward moving distance of the illuminating area is optimal while the eyes of the user are not directly illuminated by light, the whole desk lamp can keep a longer distance with the user, and the usable space of the desktop is enlarged.

Further, as shown in fig. 2, the lamp further includes a base 200, a lamp body 300, and a lamp arm 400; the lamp cap 100 is fixed on the base 200 through the lamp arm 400 and the lamp body 300; the lamp head 100 is connected with the lamp arm 400 through the first rotating member 500; the lamp arm 400 and the lamp body 300 are connected by the second rotating member 600. Specifically, the lamp body 300 and the lamp arm 400 are straight sections, are assembled with the first rotating member 500 and the second rotating member 600 in an inserting manner, and are fixed in screws, buckles and the like, the first rotating member 500 is used for adjusting the direction of the lamp cap 100, and the second rotating member 600 is used for adjusting the height of the lamp cap.

Further, as shown in fig. 5 to 7, the first rotating member 500 includes a first rotating shaft 510 and a second rotating shaft 520; the first rotating shaft 510 is near one end of the lamp cap 100; the second shaft 520 is close to one end of the lamp arm 400; the rotation directions of the first and second rotating shafts 510 and 520 are perpendicular to each other; the second rotating shaft 520 rotates on a vertical plane; specifically, the first rotating shaft 510 rotates horizontally for adjusting the horizontal position of the lamp head 100, and the second rotating shaft 520 rotates in the vertical direction for adjusting the pitch angle of the lamp head 100.

The second rotating member 600 rotates in the same direction as the second rotating shaft 520. The second rotating member 600 is also rotated in the vertical direction, and functions to rotate the lamp arm 400 on the vertical plane, i.e. to adjust the height of the far end (the end far away from the lamp body) of the lamp arm 400, and when the lamp arm 400 rotates, the lamp holder 100 is driven to move, i.e. to adjust the height of the lamp holder 100.

Further, as shown in fig. 3, the light emitting part 110 includes a PCB lamp panel 111 and a lens 112; PCB lamp panel 111 and lens 112 are both parallel to each other.

Further, the lens 112 is a low glare lens. The direct light of the light source is refracted, glare is reduced, visual fatigue is avoided, and particularly, after the LED or similar point light source is refracted and scattered by the lens, the light is softer.

Further, as shown in fig. 2, the base 100 is arc-shaped, which means that the shape of the base 100 is arc-shaped when looking down or looking up on a horizontal plane, and correspondingly, the shape of the light emitting part 110 is also arc-shaped, and the opening direction of the arc is toward the direction of the user of the desk lamp, and the inclined arrangement of the light emitting part 110 is combined, so that the projection range of the desk lamp is wider, the position of the user can be illuminated in a wide range, and the brightness of the eye area of the user is uniform.

Above-mentioned front lighting table lamp owing to adopted the illuminating part that the slope set up, can throw light to user's direction, makes the illumination area to the characteristics of user's direction skew, makes the user when using, enlarges the desktop space, and the user can not look directly the light source simultaneously, therefore the front lighting table lamp that this application relates to has not dazzling, reduces the advantage of asthenopia, combines the illuminating part of circular-arc and slope, realizes the effect of evenly throwing light on a large scale.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and although the present invention has been disclosed with reference to the preferred embodiment, it is not intended to limit the present invention, and any person skilled in the art can make modifications or changes to equivalent embodiments with equivalent changes when using the technical contents disclosed above without departing from the technical scope of the present invention, and any simple modifications, equivalent changes and modifications made to the above embodiments by the technical matters of the present invention are all within the scope of the technical solution of the present invention.
