Detailed Description

For the purposes, technical solutions and advantages of the present application, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

The following describes in detail the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.

Referring to fig. 1 to 7, the embodiment of the present application discloses a desk lamp, which includes a light emitting portion 10 and a light emitting portion mounting base 20, wherein the light emitting portion mounting base 20 is a mounting base of the light emitting portion 10 for mounting the light emitting portion 10. The light emitting portion mounting base 20 includes a housing 201 and a honeycomb light-transmitting plate 202 provided on an opening side of the housing 201, the honeycomb light-transmitting plate 202 being connected to the housing 201 to form a light source accommodating chamber for accommodating the light emitting portion 10. In the embodiment of the present application, the light emitting section 10 includes the light emitting body 102, and the honeycomb light transmitting plate 202 is provided with the honeycomb through holes 202a opposed to the light emitting body 102.

In the desk lamp disclosed by the embodiment of the application, the illuminant is positioned in the light source accommodating cavity, the honeycomb light-transmitting plate 202 is provided with the honeycomb through holes 202a opposite to the illuminant, and the honeycomb through holes 202a have a certain depth, so that the shading effect can be improved, and the better anti-glare problem can be achieved. Compared with the background art, the desk lamp disclosed by the application can avoid the problem that the coating is easy to fall off when the chemical coating is adopted for anti-glare. Meanwhile, the adoption of the honeycomb light-transmitting plate 202 can also improve the attractiveness of the desk lamp.

The structure of the light emitting part mounting base 20 may be various, and the light emitting part mounting base 20 may be an open structure, i.e., the light emitting part 10 can be directly contacted with the surrounding environment, and the light emitting part mounting base 20 may be a closed structure, i.e., the light emitting part 10 can be located in a closed environment isolated from the surrounding environment.

The honeycomb light-transmitting plate 202 can be fixedly connected with the shell 201 through a threaded connector, and preferably, the honeycomb light-transmitting plate 202 can also be fixedly connected with the shell 201 through a buckle, and the dismounting efficiency can be improved through the buckle connection.

In the embodiment of the present application, the honeycomb through hole 202a is opposite to the illuminant 102, which means that the honeycomb through hole 202a is opposite to the illuminant 102, so that the light emitted by the illuminant 102 can be projected out through the honeycomb through hole 202a. Specifically, the light emitters 102 are plural, the honeycomb through holes 202a are plural, and the plural honeycomb through holes 202a are opposed to the light emitters 102 one by one. In other preferred embodiments, the number of through-holes 202a may be greater than the number of light emitters 102, but it should be ensured that each light emitter 102 is provided with its corresponding through-holes 202a. In order to enhance the irradiation effect of the light emitter 102, it is preferable that the projection of the light emitter 102 in the cross-sectional direction perpendicular to the opposite honeycomb through-holes 202a is located at the center of the cross-section. Here, the cross section refers to a cross section of the honeycomb through-hole 202a in a direction perpendicular to the axis thereof.

Referring to fig. 1 to 3, in the desk lamp disclosed in the embodiments of the present application, the light emitting portion 10 may be provided with a first connection hole 100, the first connection hole 100 is a bar-shaped hole extending along the length direction of the light emitting portion 10, specifically, the first connection hole 100 may be a waist-shaped hole, and the waist-shaped hole is widely applied and easy to manufacture.

As described above, the light emitting portion mounting base 20 is a mounting base of the light emitting portion 10 for mounting the light emitting portion 10. The light emitting part mounting base 20 may be provided with a connection protrusion 200, one end of the connection protrusion 200 passes through the first connection hole 100 to be used for fixing the light emitting part 10, and an avoidance gap 100a may be formed between the connection protrusion 200 and both ends of the first connection hole 100, and the avoidance gap 100a is used for avoiding thermal deformation of the light emitting part 10. Specifically, the coupling protrusion 200 may have a cylindrical shape.

As is known, the light emitting part 10 is a heat generating component of a desk lamp, and the material (typically including an aluminum substrate) of the light emitting part 10 is generally different from the material (typically plastic) of the light emitting part mounting base 20, so that thermal expansion deformation of the light emitting part 10 is large. Under the premise that the connection protrusion 200 is matched with the first connection hole 100 to realize the assembly of the light-emitting part 10 and the light-emitting part mounting base 20, the light-emitting part 10 can stretch in the length direction with larger deformation through avoiding the gap 100a, the light-emitting part mounting base 20 cannot be interfered by the connection protrusion 200, and the influence of the deformation of the light-emitting part mounting base 20 on the deformation of the light-emitting part 10 can be reduced.

Of course, the first connection hole 100 may be disposed on the light emitting portion mounting base 20, and correspondingly, the connection protrusion 200 is disposed on the light emitting portion 10, in this case, the connection protrusion 200 and the first connection hole 100 cooperate to still achieve the assembly between the light emitting portion 10 and the light emitting portion mounting base 20, and meanwhile, an avoidance gap is formed between the connection protrusion 200 and both ends of the first connection hole 100.

In this preferred embodiment, the light emitting portion 10 and the light emitting portion mounting base 20 are assembled through the first connecting hole 100 and the connecting protrusion 200, the first connecting hole 100 is a bar-shaped hole extending along the length direction of the light emitting portion 10, and the avoiding gaps 100a are formed between the connecting protrusion 200 and both ends of the first connecting hole 100, so that the deformation of the light emitting portion mounting base 20 is not affected when the light emitting portion 10 is deformed in the length direction with a large deformation amount. Therefore, the desk lamp disclosed in the embodiment of the application can also solve the problem that the assembly stability between the light-emitting part 10 and the light-emitting part mounting base 20 is affected due to the large thermal deformation of the light-emitting part 10.

More preferably, a relief gap may be formed between the light emitting portion 10 and both side walls of the first connection hole 100. Since the deformation of the light emitting portion 10 in the width direction thereof is small or the deformation accumulation is small, the size of the escape gap formed between the light emitting portion 10 and the both side walls of the first connection hole 100 can be small, and thus the assembling stability between the light emitting portion 10 and the light emitting portion mounting base 20 is not greatly affected.

In a preferred embodiment, the light emitting part 10 may include a PCB (Printed Circuit Board ) board 101 and a plurality of the light emitting bodies 102 disposed on the PCB board 101, and the light emitting bodies 102 are bulbs or light emitting diodes. The first connection hole 100 is opened on the PCB board 101. The plurality of luminous bodies 102 are distributed on the PCB 101, so that the whole luminous part 10 has a relatively balanced luminous effect, and meanwhile, the aim of adjusting the whole luminous effect of the luminous part 10 can be fulfilled by adjusting the number of the luminous bodies 102.

Preferably, the side wall of the honeycomb through hole 202a may be a telescopic side wall, and the telescopic side wall can stretch along the depth direction of the honeycomb through hole 202a, so as to change the height of the honeycomb through hole 202a, thereby achieving the purpose of adjusting the shading angle. The shielding effect on light can be adjusted by the shielding angle, and then the purpose of adjusting the radiation area of the light is achieved. As shown in fig. 5 and 6, the light shielding angle was 25 ° when the height of the partial honeycomb through-holes 202a shown in fig. 5 was 4mm, and 16 ° when the height of the partial honeycomb through-holes 202a shown in fig. 6 was 2.5 mm. The user can adjust the height of the telescopic side wall according to the self requirement, and then adjust the shading angle of the honeycomb through hole 202a.

In another preferred embodiment, the honeycomb panel 202 may be attached to the open side of the housing 201 by a telescoping connection (e.g., a tie rod) that is used to adjust the distance between the honeycomb panel 202 and the illuminant 102. The distance between the honeycomb light-transmitting plate 202 and the illuminant 102 can be changed to adjust the light shielding angle, so as to realize different light shielding effects.

Referring to fig. 1 again, the desk lamp disclosed in the embodiments of the present application may further include a light-diffusing plate 30, where the light-diffusing plate 30 is disposed between the light-emitting portion 10 and the honeycomb light-transmitting plate 202, and the light-diffusing plate 30 is used for performing scattering treatment on the light generated by the light-emitting portion 10, so that the light is more uniformly projected from the honeycomb through holes 202a of the honeycomb light-transmitting plate 202, and finally the illumination effect of the desk lamp can be improved.

The light diffusion plate 30 may be provided with a second coupling hole adapted to the coupling protrusion 200, and the coupling protrusion 200 is provided on the light emitting part mounting base 20, in which case one end of the coupling protrusion 200 may sequentially pass through the first coupling hole 100 and the second coupling hole to fix the light emitting part 10 and the light diffusion plate 30. As described above, one end of the coupling protrusion 200 may be a screw end, which is fixed to the light emitting part 10 and the light diffusing plate 30 by being engaged with a nut. Of course, one end of the connection protrusion 200 may be melted by a hot melting process, thereby achieving the purpose of fixing the light emitting part 10 and the light diffusion plate 30.

The light-diffusing plate 30 may be fixed by other means, and referring again to fig. 3, the light-diffusing plate 30 may be fixed to the honeycomb light-transmitting plate 202. The light diffusion plate 30 may be provided with second coupling holes, and correspondingly, the honeycomb light transmission plate 202 may be provided with positioning protrusions 202b, and the second coupling holes are fixedly coupled with the positioning protrusions 202b to achieve fixation of the light diffusion plate 30. Of course, the second connection holes may be provided on the honeycomb light-transmitting plate 202, and correspondingly, the positioning protrusions 202b are provided on the light-diffusing plate 30. The second connecting hole and the positioning protrusion 202b can be fixedly connected through a clamping connection, and the fixing connection of the second connecting hole and the positioning protrusion 202b can also be realized through hot melting of the positioning protrusion 202 b.

Referring to fig. 7-9, the desk lamp disclosed in the embodiments of the present application includes a supporting mechanism, where the supporting mechanism is a supporting component of the whole desk lamp. In a particular embodiment, the support mechanism can include a support arm 40 and a base 50. The bottom end of the support arm 40 is connected to the base 50, and the top end of the support arm 40 is connected to the light emitting part mounting base 20. The support arm 40 may be a telescopic structure, such as a pull rod, and the telescopic movement of the support arm 40 can adjust the illumination of the light emitting part 10 at different heights.

In a preferred embodiment, the honeycomb light-transmitting plate 202 may be sandwiched between the top end of the support arm 40 and the housing 201, where the honeycomb light-transmitting plate 202 is provided with a hole for avoiding, and the top end of the support arm 40 may be provided with a threaded connection member capable of passing through the hole for avoiding and fixedly connected to the housing 201. Under the premise that the supporting arm 40 is fixed with the shell 201, the honeycomb light-transmitting plate 202 can be fixed in an auxiliary mode, and the assembly of the honeycomb light-transmitting plate 202 is stable.

One end of the light emitting part mounting base 20 may be connected to the top end of the support arm 40 to form a revolute pair for rotating the other end of the light emitting part mounting base 20, thereby making the end close to or far from the support arm 40. When the other end of the light emitting part mounting base 20 is rotated to approach the support arm 40, the light emitting part mounting base 20 is in a folding stroke, and finally the end is abutted against the support arm 40 so that the light emitting part 10 and the light emitting part mounting base 20 are in a folded state (i.e., folded state). Conversely, when the other end of the light emitting part mounting base 20 is turned away from the support arm 40, the light emitting part mounting base 20 is in the expanding stroke, and eventually the end is away from the support arm 40, so that the light emitting part 10 and the light emitting part mounting base 20 are in the expanded state.

In the working process, the rotating shaft fixing seat 600 rotates relative to the rotating shaft supporting seat 602 through the rotating shaft 601, so that the other end of the light-emitting part mounting base 20 rotates relative to the supporting arm 40. The revolute pair assembly 60 can lead to part wearing and tearing at pivoted in-process, and above-mentioned revolute pair assembly 60 divide into three subassembly, and the user of being convenient for carries out the individual change to the part, and then can reduce the cost of maintenance of user to the desk lamp.
