Example 1

Fig. 1 is an exploded view of a desk lamp holder according to the present embodiment, fig. 2 is an assembled view of the desk lamp holder according to the present embodiment at one viewing angle, fig. 3 is an assembled view of the desk lamp holder according to the present embodiment at another viewing angle, and referring to fig. 1 to 3, a desk lamp holder 100 is used for illuminating a local environment of a desk or a desk top, the desk lamp holder 100 includes a housing assembly 1, a light source assembly 2 and an optical assembly 3, wherein the housing assembly 1 is used as a frame of the desk lamp holder 100, and the light source assembly 2 and the optical assembly 3 are installed inside the housing assembly 1. In addition, a PCT board, a power supply assembly and a control module (not shown) are also installed inside the housing assembly 1 to supply and control the power to the light source module 2.

The housing assembly 1 comprises a first cover 11, a second cover 12 and a base assembly 13, wherein the first cover 11 and the second cover 12 are respectively arranged on the upper side and the lower side of the base assembly 13, and the first cover 11 and the second cover 12 are fixed together in a buckling connection mode. Specifically, the first cover 11 is provided with a clamping groove (not shown in the figure), the second cover 12 is correspondingly provided with a clamping block 120, and when the cover is installed, the clamping block 120 is in buckled connection with the clamping groove, so that the base component 13 is included, and a closed installation cavity is formed. The first cover 11 and the second cover 12 adopt a fastening/clamping connection mode, so that the installation of the desk lamp cap can be facilitated. In some embodiments, the first cover 11 and the second cover 12 may be fastened together by a screw connection, or a screw penetrates through the base component 13, so that the first cover 11, the base component 13 and the second cover 12 are fastened together, and the whole structure is firm and stable.

Fig. 4 is a sectional view of the desk lamp head of the present embodiment in a first base, fig. 5 is a sectional view of the desk lamp head of the present embodiment in a second base, and referring to fig. 4 and 5 in combination on the basis of fig. 2, the base assembly 13 includes a first base 131 and a second base 132, wherein the second base 132 is disposed in the middle of the desk lamp head 100, and the first base 131 is disposed in a wing shape on both sides of the second base 132. In the present embodiment, the first bases 131 located at both sides of the second base 132 have the same structure, and provide a base structure for mounting the three-stage light source. Moreover, the first base 131 is symmetrically disposed at two sides of the second base 132, so that the desk lamp base 100 has a novel shape like an airplane tail.

Correspondingly, the second cover 12 below the base assembly 13 is provided with a first receiving groove 121 and a second receiving groove 122, wherein the first base 131 is mounted in the first receiving groove 121, and the second base 132 is mounted in the second receiving groove 122.

In the lamp holder of the desk lamp of the present embodiment, the light source assembly 2 is disposed on the side wall of the base assembly 13, it can be understood that the light source assembly 2 of the present embodiment adopts a side-emitting manner, which is different from the direct type emergent light emission or the reflective light emission in the existing desk lamp. As a means for processing the light emitted from the light source module 2, the optical module 3 includes a light guide plate 31 and a diffusion plate 32, wherein the side surface of the light guide plate 31 faces the light source module 2, and the diffusion plate 32 is disposed closely to the light exit surface of the light guide plate 31.

The light source assembly 2 includes a first light source 21, a second light source 22 and a third light source 23, wherein the first light source 21 is a main light source of the desk lamp holder 100, the second light source 22 is a light supplementing light source of the desk lamp holder 100, and the third light source is a back light emitting light source of the desk lamp holder 100. The first light source 21, the second light source 22 and the third light source 23 emit light from side surfaces, but the light rays emitted finally have different emitting directions. The emergent light rays of the first light source 21 and the second light source 22 finally emerge to the target illumination area and can be adjusted to vertically downwards emerge or obliquely downwards emerge; the outgoing light of the third light source 23 finally exits toward the object on the back of the desk lamp, for example, toward the wall, and the outgoing direction of the third light source 23 is horizontal or obliquely upward or downward.

Specifically, the first light source 21 is disposed on a sidewall of the first base 131, which is a first rear sidewall 1311 remote from the user. The first light source 21 includes an aluminum substrate 211 and lamp beads 212 uniformly laid on the aluminum substrate 211, and the lamp beads 212 are distributed on the aluminum substrate 211 in an array. In the present embodiment, the lamp beads 212 are disposed on the aluminum substrate 211 by using an SMD patch, and in some embodiments, a COB light source may be disposed. Further, in this embodiment, a connection plate 1312 is attached to and fixed to the first light source 21. The connection plate 1312 has an L-shaped structure, one surface of the connection plate 1312 is fixed to the aluminum substrate of the first light source 21 in a bonding manner, and the other surface is fixed to the first rear sidewall 1311 in a bonding manner, so that the first light source 21 is mounted on the first rear sidewall 1311 of the first base 131, and the lamp beads of the first light source 21 can emit light laterally.

The light emitted from the first light source 21 is emitted through the light guide plate 31 and the diffusion plate 32. Specifically, the lamp beads 212 of the first light source 21 face the incidence plane 311 of the light guide plate 31, are processed by the light guide plate 31, and enter the diffusion plate 32 from the exit plane 312. The light guide plate 31 further has a backlight plane 313, and the backlight plane 313 is parallel to the exit plane 312 and perpendicular to the incident plane 311.

The light guide plate 31 may be made of acrylic (PMMA, chemical name is polymethyl methacrylate), and the light guide plate 31 may be made of PC, glass or other organic glass materials. The light guide plate 31 of the present embodiment adopts optical acrylic, which can uniformly guide the LED light incident from the side surface out of the front surface through dot refraction. And the light guide plate of acrylic has high transparency, light transmittance of over 92 percent, soft light and clear vision.

As described above, the light emitted from the lamp beads 212 of the first light source 21 of the present embodiment enters the incident plane 311 of the light guide plate 31 at the side surface, and the light emitted from the lamp beads 212 is a large angle light. Those skilled in the art will appreciate that when a ray enters a lower index medium from a higher index medium, the refracted ray will disappear if the angle of incidence is greater than the critical angle, and all of the incident ray will be reflected without entering the lower index medium. The refractive index of the light guide plate 31 of the present embodiment is higher than that of air, so that the light emitted from the first light source 21 is totally reflected and guided through the light guide plate 31, and then enters the diffusion plate 32 from the exit plane 312. It should be noted that, the backlight plane 313 may be provided with a reflective structure, for example, a plurality of light guiding reflective structures recessed toward the exit plane 312 may be arranged in an array; or a reflective optical element such as reflective paper, reflective film, etc. is added.

After the light rays emitted by the first light source 21 are processed by the total reflection light guide structure formed by surrounding the incidence plane 311, the backlight plane 313 and the emergent plane 312, the illumination intensity below the emergent plane 312 is reduced, and as the light rays are emitted from the emergent plane 312 after traveling a certain distance between the total reflection light guide structures, the illumination is distributed in a large area, so that the soft light and anti-dazzle illumination effect is obtained, and the illumination efficiency is improved.

Light emitted from the emission plane 312 of the light guide plate 31 enters the diffusion plate 32 to be processed. The diffusion plate 32 uniformly diffuses and guides the light of the light guide plate 31, and functions as a blurred dot.

Referring to fig. 5, the second light source 22 is disposed on a sidewall of the second base 132, which is a second rear sidewall 1321 remote from the user. Similar to the first light source 21, the light emitted from the second light source 22 is also emitted through the light guide plate 31 and the diffusion plate 32. The second light source 22 is installed on the desk lamp base in a similar manner to the first light source 21, and both of them emit light from the side surface, and are treated by the light guide plate 31 and the diffusion plate 32, and then are irradiated to the target illumination area. The light treatment method of the light guide plate 31 and the diffusion plate 32 for the second light source 22 is similar to the light treatment method of the light guide plate 31 and the diffusion plate 32 for the first light source 21, and will not be described here again.

However, there are some differences between the second light source 22 and the first light source 21, for example, the first light source 21 is a main light source of the desk lamp holder 100, the second light source 22 is a light supplementing light source of the desk lamp holder 100, and the first light source 21 and the second light source 22 are matched with each other, so that the illumination area can be enlarged, the central light intensity is improved, and meanwhile, the bright-dark partition is reduced. Through the optimal design, the installation position of the second light source 22 on the desk lamp cap 100 is slightly lower than that of the first light source 21 on the desk lamp cap 100.

The first light source 21 as a main light source and the second light source 22 as a supplementary light source are mutually matched, and both emit light laterally at the same time, and are subjected to the treatment of the light guide plate 31 and the diffusion plate 32 of the optical assembly 3. The light guide plate enables light entering from the side to be totally reflected, so that the phenomenon that the illuminance of the area of the desk lamp close to the lower part of the lamp cap is higher is reduced, namely, the light guide plate 31 can reduce the brightness of the lower part of the lamp cap 100 of the desk lamp, and more light energy is projected to the peripheral area irradiated by the desk lamp; on the one hand, the brightness of the peripheral area of the lamp cap is improved, on the other hand, the bright and dark zoning phenomenon is reduced, and meanwhile, the visual comfort of a user is improved.

Fig. 6 is a partially enlarged view of a section A-A of the first base, and referring to fig. 6 on the basis of fig. 4, the third light source 23 is also disposed on a side wall of the first base 131, which is also a first rear side wall 1311 far from the user. Further, a groove 1312 is provided on the first base 1311, and the third light source 23 is fitted into the groove 1312. The light emitting direction of the third light source 23 of the present embodiment is deviated from the light emitting direction of the first light source 21. It can be understood that the first light source 21 and the third light source 23 both adopt a side-emitting mode, but the side of the first light source 21 emits light toward the direction of the user, and then the light is emitted vertically downward or obliquely downward after being processed by the light guide plate 31 and the diffusion plate 32; the side surface of the third light source 23 emits light in a direction away from the user, such as light emitted towards the wall, so that the brightness of the peripheral area of the lamp cap can be further improved, and as the third light source 23 is arranged adjacent to the first light source 21, when the third light source 23 irradiates towards the wall, the distance between the third light source and the wall is smaller than the distance between the first light source and the wall, and the phenomenon of dazzling illumination emission is not easy to occur. The third light source 23 is a back-side light source, which is far away from the wall, so that the contrast of brightness can be reduced, and the visual comfort can be improved.

In some embodiments, a lens 231 may also be disposed on the light emitting surface of the third light source 23, and the light emitted by the third light source 23 is further processed to reduce glare.

It should be noted that, among the first base 131 and the second base 132 of the base assembly 13, the display panel 133 is further disposed, and the display panel 133 is disposed away from the light source assembly 2 and faces the user. The display panel of the present embodiment is a display panel that can be operated controllably. The display panel corresponds to a corresponding touch functional area, such as a functional touch case provided with a switch, brightness adjustment, color temperature adjustment, night light, display illumination and the like. And the display panel of the second base correspondingly displays the temperature and humidity values. These functions can be customized and adjusted according to the needs of the user.

According to the table lamp cap provided by the embodiment, the first light source, the second light source and the third light source all adopt a side light emitting mode, so that light can be prevented from directly entering or reflecting to an illumination area or eyes, and glare is reduced. In addition, the first light source serving as the main light source, the second light source serving as the light supplementing light source and the third light source serving as the back light emitting light source are matched with each other, so that the contrast of brightness can be reduced, and the illumination comfort level is improved.

In the desk lamp base 100, the second base 132 and the first cover 11 above the second base 132 are respectively provided with a connection hole 111 for connecting with the lamp post 300. The lamp post 300 is a three-stage adjustable rotating member, and the lamp post 300 is respectively provided with a first rotating member 301, a second rotating member 302 and a third rotating member 303. The first rotating member 301, the second rotating member 302 and the third rotating member 303 are engaged with each other to perform horizontal rotation, vertical rotation and rotation, thereby realizing 360 ° omni-directional rotation to cover a lighting range required by a user.

The desk lamp of the embodiment adopts three-section type luminescence, and the central light intensity is high and controllable, so that the illumination area is wide; in addition, the lamp pole is a three-section type adjustable rotating piece, so that the illumination angle and the illumination area can be conveniently adjusted, and the omnibearing desktop illumination is realized.
