The lamp cap 10 is installed on the top end of the lamp arm 20, and the lamp holder 30 is installed on the bottom end. The lamp arm 20 includes an arm case 21, a second light emitting assembly 22 and a second light guide element 23 mounted in the arm case 21, the second light emitting assembly 22 being disposed opposite to an end of the second light guide element 23. The second light guiding element 23 has a third light emitting surface 231, and the third light emitting surface 231 is opposite to the light emitted from the first light emitting surface 141.
The desk lamp 100 of the present embodiment has the advantages that: the light of the first light emitting assembly 13 is emitted from the first light emitting surface 141 and the second light emitting surface 142 through the first light guiding element 14, the light emitted from the first light emitting surface 141 illuminates the working surface downward, and the light emitted from the second light emitting surface 142 illuminates the upper space of the lamp cap 10 upward. The light of the second light emitting element 22 is emitted from the third light emitting surface 231 of the second light guiding element 23 through the second light guiding element 23, and illuminates the back space of the lamp arm 20. That is, the desk lamp 100 of the present embodiment can illuminate the upper space of the lamp cap 10 and the back space of the lamp arm 20 at the same time, and compared with the conventional desk lamp, the desk lamp 100 of the present embodiment can illuminate the entire background facing the user, and the brightness difference between the entire background and the working surface is small, so that the eye comfort of the user can be improved.
The first light guide element 14 in this embodiment is a light guide plate, and the light guide plate may be a laser dotting light guide plate, in which laser dotting is performed on the surface of the light guide plate, and light is diffused by each light guide point. However, since the surface of the laser dotting light guide plate has a plurality of light guide points, the light guide plate has poor permeability when the lamp cap 10 is turned on and off, thereby making the light guide plate have poor visual effect. In order to improve the permeability of the light guide plate of the lamp cap 10, the light guide plate of the lamp cap 10 of this embodiment does not adopt the light guide plate of dotting, and transparent diffusion particles are distributed in the light guide plate of the lamp cap 10 of this embodiment, and light diffusion is carried out through the transparent diffusion particles, so that the light guide plate in the lamp cap 10 has better permeability and better visual effect when the lamp cap 10 is turned on and off.
The second light guide element 23 of the present embodiment is a light guide plate. Preferably, in order to improve the permeability of the light guide plate of the lamp arm 20, the light guide plate of the lamp arm 20 of this embodiment does not adopt the light guide plate of dotting, transparent diffusion particles are distributed in the light guide plate of the lamp arm 20 of this embodiment, and light diffusion is performed through the transparent diffusion particles, so that the light guide plate of the lamp arm 20 has better permeability and better visual effect when the lamp arm 20 is turned on and off.
The second light guiding element 23 of the present embodiment is disposed along the length direction of the lamp arm 20, the top end of the second light guiding element 23 extends to the top end of the arm casing 21, and the bottom end of the second light guiding element 23 extends to the bottom end of the arm casing 21, so that the second light guiding element 23 can illuminate a larger background area, the effect of background illumination is improved, and the brightness difference between the background and the working surface can be reduced.
The number of the second light emitting assemblies 22 in the present embodiment may be one, and when the number of the second light emitting assemblies 22 is one, the second light emitting assemblies 22 may be disposed at the top end of the lamp arm 20 opposite to the top end of the second light guiding element 23. Or the second light emitting assembly 22 may be disposed at the bottom end of the lamp arm 20 opposite to the bottom end of the second light guiding member 23. The brightness of the portion of the light beam of the second light guiding element 23 that is closer to the second light emitting element 22 is greater, that is, the uniformity of the light beam is poorer by using one second light emitting element 22, and the range of background illumination is smaller. As shown in fig. 3 and 4, in order to improve the uniformity of light and the range of background illumination, the number of the second light emitting assemblies 22 in the present embodiment is preferably two, and the two second light emitting assemblies 22 are respectively disposed opposite to the two ends of the second light guiding element 23.
As shown in fig. 1, the head shell of the lamp cap 10 includes an upper shell 11 and a lower shell 12, and the upper shell 11 and the lower shell 12 are connected by a snap-fit connection, and the connection and the disassembly are rapid and convenient. The upper case 11 and the lower case 12 are both disc-shaped structures, a circular upper light-transmitting portion 111 is provided at the center of the upper case 11, the upper light-transmitting portion 111 may be a through hole penetrating the upper case 11, or the upper light-transmitting portion 111 may be made of a transparent material.

The upper light-transmitting portion 111 and the lower light-transmitting portion 121 are disposed opposite to the first light-guiding element 14 for emitting light.
Since the first light emitting element 13 has a high luminance and a large heat generation amount, the present embodiment preferably has a heat sink 15 mounted in the head case in order to dissipate heat of the first light emitting element 13. The first light guiding element 14 is in a disc-shaped structure, and in order to better cooperate with the first light guiding element 14, the first light emitting component 13 of the present embodiment includes a ring 132 and a plurality of first light sources 131, the plurality of first light sources 131 are distributed on the inner wall of the ring 132, and the first light emitting component 13 is annularly disposed on the side wall of the first light guiding element 14. In order to improve the heat dissipation effect of the heat sink 15, preferably, the heat sink 15 of the present embodiment has a ring structure, the heat sink 15 is annularly disposed on the outer wall of the first light emitting component 13 and is in close contact with the head shell, and the heat sink 15 may be made of aluminum metal, so that the heat dissipation effect is good. After the desk lamp 100 is turned on, the heat of the first light source 131 is transferred to the head case through the heat sink 15 to be emitted to the outside.
As shown in fig. 1, the lamp socket 30 of the present embodiment includes a socket housing including a disc-shaped upper cover 31 and a disc-shaped lower cover 32, and the upper cover 31 and the lower cover 32 are connected by snap-fit engagement. In order to enable the lamp socket 30 to be stably placed on the surface of an object such as a table top, a weight 36 is provided in the socket case. The upper cover 31 is disposed opposite to the lower case 12 toward the base 10. The lower cover 32 is for placement on a surface of an object such as a table top. Preferably, the center of the upper cover 31 is provided with a mounting hole, and the display 37 is mounted on the mounting hole, and the display 37 may be made of a non-transparent material or a transparent material. Preferably, the display body 37 of the present embodiment is made of a transparent material, which can enhance the technological sense of the lamp socket 30.

The touch key of the embodiment can be made of a copper foil of a circuit board or a transparent conductive film. Preferably, the touch key is made of a transparent conductive film, so that the technological sense of the touch key is improved, and the display 37 is more attractive. The transparent conductive film is adopted for the touch keys, so that the user cannot see the touch keys, and therefore, in order to display the positions of the touch keys, the positions of the touch keys are marked on the outer surface of the display body 37, so that the user can find the corresponding touch keys conveniently.
The control board 33 can control the luminance of the first light emitting component 13 by controlling the light emitting quantity of the first light source 131, and the user can control the luminance of the first light emitting component 13 by touching the key. Since the sensitivity of the human eye to the brightness variation of the first light emitting component 13 is low, in order to facilitate visual observation of the brightness variation of the first light emitting component 13, it is preferable that a transparent ring 38 is mounted on the upper cover 31, and accordingly, a third light emitting component 34 is disposed in the seat shell, and the third light emitting component 34 is disposed opposite to the ring 38. The third light emitting assembly 34 includes a third light source 341 and an annular plate 342, the number of the third light sources 341 being several, and the several third light sources 341 being uniformly distributed on the annular plate 342.

The ratio of the area of the light emitting portion of the circular ring 38 to the area of the circular ring 38 is a light emitting ratio, which is proportional to the brightness of the first light emitting element 13. I.e. the larger the area of the ring 38 emitting light, the higher the brightness of the first light emitting assembly 13. When the brightness of the first light emitting element 13 is half of the highest brightness, half of the ring 38 emits light, and half does not emit light. The user can intuitively understand the brightness of the first light emitting component 13 by observing the light emitting area of the ring 38, so that the user can accurately adjust the brightness of the first light emitting component 13.
Preferably, in order to improve the light emitting efficiency of the third light source 341, the present embodiment further provides a reflector 35 in the housing, and the light of the third light emitting component 34 is emitted to the ring 38 through the reflector 35.
In order to improve accuracy of the light emission ratio observed by the human eye, the area of the ring 38 needs to be set larger, and in order to save space on the basis of ensuring that the ring 38 has a larger area, in this embodiment, the display body 37 and the ring 38 are both installed in the installation hole and the ring 38 is annularly arranged on the display body 37.
