Description

Technical Field

[0001] The utility model relates to a lamp, in particular to a table lamp. Background Art

[0002] A desk lamp is an electric lamp placed on a desk. Current desk lamps typically feature a light source, such as a bulb or LED, mounted on a stand. A reflector is installed around the light source, refracting the light from the light source. During use, if the user's eyes are located below the reflector, when looking straight ahead or up, the light from the light source may shine directly into the user's eyes. This can cause discomfort and, if prolonged, can impair vision. Therefore, a desk lamp that prevents light from the light source from shining directly into the user's eyes is urgently needed. Utility Model Content

[0003] The purpose of the present utility model is to provide a desk lamp to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the utility model to solve its technical problems is:

[0005] A desk lamp comprises: a lamp stand; a lamp housing connected to the top of the lamp stand, with the side of the lamp housing connected to the lamp stand serving as the mounting side, and a light outlet provided on the bottom side of the lamp housing; a reflective layer connected to the inside of the lamp housing; a light source connected to the inside of the lamp housing, the light source being located on a side of the light outlet away from the mounting side, the light source being able to emit light toward the reflective layer, and the reflective layer being able to refract part of the light from the light source downward out of the light outlet.

[0006] This technical solution has at least the following beneficial effects: the lamp stand can be used to provide support and stability for the whole when placed, and the side where the lamp housing is connected to the lamp housing is the installation side. When in use, the user's position is close to the other side of the lamp housing, thereby reducing the interference of the lamp stand on the user's activities. Since the user is located away from the installation side of the lamp housing, and the light source in the lamp housing is located on the side of the light outlet away from the installation side, when the user looks straight ahead or up under the lamp housing, the user will not directly observe the light source from the light outlet. Part of the light from the light source is emitted from the light outlet toward the direction close to the lamp stand, and part of the light is refracted through the reflective layer and then emitted downward from the light outlet. In this way, when the user uses the desk lamp, it can effectively prevent the light from the light source from directly shining into the user's eyes and causing discomfort and other problems, thereby improving lighting comfort.

[0007] As a further improvement to the above technical solution, a connecting plate is connected between the inner top and bottom surfaces of the lamp housing. The side of the connecting plate near the light source is shaped like an arc that bulges toward the mounting side. The reflective layer is connected to the side of the connecting plate near the light source. The connecting plate connected within the lamp housing provides mounting support for the reflective layer. The curved shape of the connecting plate better refracts light from the light source onto the reflective layer downward, increasing the light output from the light outlet, thereby improving light intensity and enhancing the lighting effect.

[0008] As a further improvement of the above technical solution, the reflective layer is a reflective paper connected to the surface of the connecting plate. The reflective layer refracts the light from the light source, making the emitted light softer, thereby further improving the comfort of lighting.

[0009] As a further improvement to the above technical solution, a mounting plate is connected to the interior of the lamp housing. The mounting plate extends upwardly and at an angle away from the light outlet, and the light source is connected to a side of the mounting plate near the reflective layer. The mounting plate provides mounting support for the light source, and since the light source is mounted on the inclined mounting plate, the mounting position of the light source can be further moved inward into the lamp housing. This reduces the amount of light emitted directly from the light outlet and increases the amount of light refracted through the reflective layer, thereby improving the lighting effect.

[0010] As a further improvement to the above technical solution, a light emitting plate is connected to the light outlet in the lamp housing. The light emitting plate has the effect of diffusing and evenly distributing the light. The light refracted from the reflective layer passes through the light emitting plate and then emits outward, making the light softer and further improving the lighting comfort.

[0011] As a further improvement to the above technical solution, the light output plate includes a diffuser plate and a rhombus plate connected to the lamp housing, with the diffuser plate located on the top side of the rhombus plate. As light is emitted outward, it first passes through the diffuser plate. The diffuser plate, through its special microstructure or added light diffusing agent, scatters the light as it passes through the plate. This scattering effect changes the propagation direction of the light, dispersing the originally concentrated or direct light over a wider angle, thereby reducing glare and providing a softer and more uniform lighting effect. The light then passes through the rhombus plate. The rhombus plate, through its special surface structure, disperses the light into a large number of tiny light points, achieving a uniform, glare-proof lighting effect, thereby further improving the lighting comfort.

[0012] As a further improvement to the above technical solution, the bottom surface of the lamp housing is provided with slots on either side of the light outlet, and the two sides of the light outlet plate are respectively connected to the two slots. During installation, due to the slots provided on either side of the light outlet in the lamp housing, the two sides of the light outlet plate can be connected to the two slots. Therefore, when the light outlet plate is installed, the light outlet plate can be completely covered by the light outlet plate, achieving quick installation and fixation.

[0013] As a further improvement to the above technical solution, a backlight is provided on the mounting side, and the light source and backlight can be turned on and off separately. During use, the backlight can be turned on to illuminate the back of the lamp housing, providing more versatile functions. Moreover, the light source and backlight are independently controlled, allowing users to turn on only the light source or the backlight, or both, as needed, for greater flexibility.

[0014] As a further improvement of the above technical solution, a negative ion generator is connected to the outside of the lamp housing, which can generate negative ions, thereby helping to remove dust and purify the air.

[0015] As a further improvement to the above technical solution, the lamp stand includes a base and adjustment rods. The number of adjustment rods is multiple, and the multiple adjustment rods are sequentially connected end to end, with one adjustment rod at one end connected to the top side of the base, and the other adjustment rod at the other end connected to the mounting side. The base is placed on a surface for placing an external device, such as a desktop, to stabilize itself. During use, the position of the lamp housing and the direction of light output are adjusted by rotating the multiple adjustment rods to adapt to different lighting needs.

[0026] Reference Figures 1 to 4A desk lamp comprises a lamp stand, a lamp housing 100, a reflective layer 200 and a light source 300, wherein the lamp housing 100 is connected to the top of the lamp stand, with the side of the lamp housing 100 connected to the lamp stand being the installation side, and the user's position relative to the entire desk lamp is usually located on the other side of the lamp housing 100, that is, on the side of the lamp housing 100 away from the installation side, and a light outlet 110 is provided on the bottom side of the lamp housing 100; the reflective layer 200 and the light source 300 are respectively connected to the lamp housing 100, and the light source 300 is located on the side of the light outlet 110 away from the installation side. The light source 300 can emit light toward the reflective layer 200, and the reflective layer 200 can refract part of the light from the light source 300 downward out of the light outlet 110.

[0027] As can be seen from the above, the lamp stand can provide support and stability for the whole when it is placed, with the side of the lamp housing 100 connected to the lamp housing 100 as the installation side. When in use, the user's position is close to the other side of the lamp housing 100, thereby reducing the interference of the lamp stand on the user's activities. Since the user is located at a position away from the installation side of the lamp housing 100, and the light source 300 in the lamp housing 100 is located on the side of the light outlet 110 away from the installation side, when the user looks straight ahead or up under the lamp housing 100, the user will not directly observe the light source 300 from the light outlet 110. Part of the light from the light source 300 is emitted from the light outlet 110 in the direction close to the lamp stand, and part of the light is refracted through the reflective layer 200 and then emitted downward from the light outlet 110. In this way, when the user uses the desk lamp, it can effectively prevent the light from the light source 300 from directly hitting the user's eyes and causing discomfort and other problems, thereby improving lighting comfort.

[0028] Since the light source 300 is not installed directly in the lamp housing 100 relative to the light outlet 110, the reflective layer 200 is primarily required to refract light toward the light outlet 110 during use. To improve the efficiency of refracting light toward the light outlet 110, in this embodiment, a connecting plate 120 is connected between the top and bottom surfaces of the lamp housing 100. The side of the connecting plate 120 proximate to the light source 300 is shaped like an arc that bulges toward the installation side. The reflective layer 200 is connected to the side of the connecting plate 120 proximate to the light source 300. The connecting plate 120 is connected within the lamp housing 100 to provide mounting support for the reflective layer 200. The arcuate shape of the connecting plate 120 better refracts light from the light source 300 onto the reflective layer 200 downward, thereby increasing the light output rate from the light outlet 110 and thereby improving light intensity and enhancing the lighting effect.

[0029] The reflective layer 200 can have various structural forms. For example, the reflective layer 200 can be a rigid structural member directly mounted within the lamp housing 100, or it can be fixed to the connecting plate 120 by lamination, bonding, or other methods. In this embodiment, the reflective layer 200 is a reflective paper connected to the surface of the connecting plate 120. The reflective layer 200 refracts the light from the light source 300, making the emitted light softer, thereby further improving the comfort of lighting.

[0030] The light source 300 can be installed vertically in the lamp housing 100. At this time, the light source 300 will form a certain height in the lamp housing 100. When the light source 300 emits light, it is easy to emit light directly through the light outlet 110, especially the light outlet located at the top of the light source 300. The coverage range of the light emitted from the light outlet 110 is also closer to the rear of the lamp holder. In order to better improve the light emission effect, in this embodiment, a mounting plate 130 is connected to the lamp housing 100, and the mounting plate 130 extends upward at an angle away from the light outlet 110. The light source 300 is connected to the side of the mounting plate 130 close to the reflective layer 200. In actual applications, the light source 300 can be an LED lamp, which is installed on the side of the mounting plate 130 in the form of a light strip, or the LED lamp is installed on the side of the mounting plate 130 in the form of a plurality of lamp beads arranged at intervals. The mounting plate 130 can provide mounting support for the light source 300. The light source 300 is mounted on the inclined mounting plate 130. Since the mounting plate 130 extends upwardly and tilted away from the light outlet 110, the mounting position of the light source 300 can be further moved inwardly into the lamp housing 100, thereby reducing the light emitted directly from the light outlet 110 by the light source 300 and increasing the light refracted after passing through the reflective layer 200, thereby improving the lighting effect.

[0031] To better protect the interior of the lamp housing 100, a light-transmitting structure can be provided at the light outlet 110 of the lamp housing 100 to protect the electrical components within the lamp housing 100. Specifically, a light-emitting plate is connected to the light outlet 110 of the lamp housing 100. The light-emitting plate diffuses and evens out the light. Light refracted from the reflective layer 200 passes through the light-emitting plate before emitting outward, making the light softer and further improving the comfort of the lighting.

[0032] The light emitting plate can be simply a translucent plate. To better improve the light emitting effect, in this embodiment, the light emitting plate includes a diffuser plate 410 and a rhombus plate 420 connected to the lamp housing 100. The diffuser plate 410 is located on the top side of the rhombus plate 420. When light is emitted outward, it first passes through the diffuser plate 410. The diffuser plate 410, through its special microstructure or added light diffusing agent, scatters the light as it passes through the plate. This scattering effect changes the propagation direction of the light, causing the originally concentrated or direct light to be dispersed to a wider angle, thereby reducing glare and providing a softer and more uniform lighting effect. The light then passes through the rhombus plate 420. The rhombus plate 420, through its special surface structure, disperses the light into a large number of tiny light spots, thereby achieving a uniform, anti-glare lighting effect, thereby further improving the comfort of lighting.

[0033] To facilitate installation of the light output plate, in this embodiment, the inner bottom surface of the lamp housing 100 is provided with slots 140 on both sides of the light output port 110, and the two sides of the light output plate are respectively connected to the two slots 140. During installation, since the slots 140 are provided on both sides of the light output port 110 in the lamp housing 100, the two sides of the light output plate can be respectively connected to the two slots 140. Therefore, when installing the light output plate, the light output plate can completely cover the light output port 110, thereby achieving quick installation and fixation of the light output plate. In actual applications, the light emitting plate and the card slot 140 can be connected by being inserted from one side of the lamp housing 100 until they are positioned with each other in the card slot 140. For example, an end cover is provided on one side of the lamp housing 100. After opening the end cover, the card slots 140 on both sides of the light outlet 110 in the lamp housing 100 can be exposed. At this time, the light emitting plate is inserted into the lamp housing 100 from one side of the lamp housing 100, so that the two sides of the light emitting plate are respectively inserted into the two card slots 140, and the light emitting plate can be quickly installed. Then the end cover is connected to one side of the lamp housing 100 to prevent the light emitting plate from moving out.

[0034] In some embodiments, a backlight 500 is provided on the mounting side, and the light source 300 and the backlight 500 can control the switch separately. When in use, the backlight 500 can be turned on to provide lighting for the back position of the lamp housing 100, and the use function is more diverse. In actual applications, there can be multiple backlights 500. For example, two backlights 500 are provided on the mounting side at positions on both sides of the lamp frame. When the desk lamp needs to illuminate the rear position, the backlight 500 can be turned on for lighting, and the switch of the light source 300 and the switch of the backlight 500 are independently controlled. According to the needs of use, only the light source 300 or the backlight 500 can be turned on, or the light source 300 and the backlight 500 can be turned on at the same time to better meet different lighting methods and improve the flexibility and use experience.

[0035] In some embodiments, a negative ion generator 600 is connected to the outside of the lamp housing 100. The negative ion generator 600 mainly uses pulse circuits, overvoltage current limiting, and high and low voltage isolation technologies to boost the input DC or AC power to AC high voltage, and then obtain pure DC negative high voltage through rectification and filtering by special electronic materials. This high voltage is released through a release tip made of metal or carbon elements, and the tip DC high voltage is used to generate high corona, thereby releasing a large number of electrons at high speed. The electrons are quickly captured by oxygen molecules in the air to form negative ions, which helps to remove dust and purify the air.

[0036] When in use, the lamp stand can be used to adjust the position of the lamp housing 100. Specifically, the lamp stand includes a base 710 and an adjustment rod 720. There are multiple adjustment rods 720, and the multiple adjustment rods 720 are connected in turn by rotating end to end. One adjustment rod 720 at one end is connected to the top side of the base 710, and the other adjustment rod 720 at the other end is connected to the installation side. In actual application, two adjacent adjustment rods 720 are connected by a structure such as a rotating shaft or hinge with an angle limit, so that the two adjustment rods 720 can be positioned after relative rotation. The base 710 is placed on the placement surface of the peripheral, such as a desktop, to stabilize itself. When in use, the position and light output direction of the lamp housing 100 are adjusted by rotating and adjusting the multiple adjustment rods 720 to adapt to different lighting needs.

[0037] The above specifically describes the preferred embodiments of the present invention, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
