Embodiment 1

[0026] Such as figure 1 and figure 2 Shown is a two-lamp lighting table lamp with light distribution function provided by this patent, which includes a lamp holder 100, a lamp body 200 and a support arm 300 connecting the lamp holder and the lamp body. The lamp body 200 includes a bottom-up The LED diffuser 210, LED lamp board 220 and lampshade upper cover 230 are connected in sequence; the lamp body heat dissipation aluminum 240 is also provided between the LED lamp board 220 and the lampshade upper cover 230; as mentioned above, the components are nested and connected in sequence.

[0027] The LED light board 220 is rectangular, and a row of uniformly arranged lamp beads is arranged in the middle of the LED light board. There are two light boards in total, and the two LED light boards are placed in an inverted V shape. The two lamp boards placed in an inverted V shape make the shading performance of the table lamp meet the national standard, and the respective power of the...

Embodiment 2

[0036] Such as image 3Shown is a three-lamp lighting table lamp with light distribution function provided by this patent, which includes a lamp holder 100, a lamp body 200 and a support arm 300 connecting the lamp holder and the lamp body. The lamp body 200 includes a bottom-up The LED diffusion sheet 210, LED lamp board 220 and lampshade upper cover 230 are connected in sequence; a lampshade bottom cover 240 is also provided between the LED lamp board 220 and the lampshade upper cover 230; as mentioned above, each component is nested and connected sequentially. The LED light board 220 is surrounded by three LED light boards, the LED light board is triangular in shape, and the lamp beads are evenly distributed on the light board, and the three LED light boards are placed in a pyramid shape, and the lights placed in the pyramid shape The board makes the shading of the table lamp meet the national standard, and the sum of the power of the three LED lamp boards is fixed, and the...

Embodiment 3

[0045] Such as Figure 4 Shown is a four-light board lighting table lamp with light distribution function provided by this patent, which is similar in structure and principle to the three-light board lighting table lamp described in Embodiment 2, the difference is that the LED light board 220 is composed of four LED light boards , the LED light board is triangular, and there are evenly distributed lamp beads on the light board, and the four LED light boards are placed in a pyramid shape, and the pyramid-shaped light boards make the shading of the table lamp meet the national standard, and the four The sum of the power of the LED light boards is fixed, and the respective power can be changed through the switch adjustment, so that the luminous intensity of the four LED light boards is different, so as to realize the four-way light distribution, that is, the irradiation area can move in four directions according to the actual use , so that the light is just irradiated at the posi...

Abstract

Disclosed is an illuminating table lamp with a light distribution function. The illuminating table lamp comprises a lamp base (100), a lamp body (200), and a support arm (300) connecting the lamp base (100) with the lamp body (200), wherein the lamp body (200) comprises an LED diffusion sheet (210), an LED lamp panel (220) and a lampshade upper cover (230) sequentially connected from bottom to top, with a plurality of said LED lamp panels (220) being comprised and arranged at an angle with the horizontal plane. Light distribution in illumination areas of the different lamp panels (220) is realized by adjusting the respective power of the different lamp panels (220); or, light distribution in different illumination areas of the lamp body (200) is realized by arranging a rotary connecting element (400) between the lamp body (200) and the support arm (300) and arranging, on the lamp body (200), a light shielding device (240) synchronously rotating with the lamp body (200), and by rotating the lamp body (200) to rotate the light shielding device (240) in a linked manner.

Description

technical field [0001] The invention relates to the field of LED lighting, and more specifically, relates to a lighting table lamp with movable shading curtain for reading and writing operations. Background technique [0002] Most of the LED lighting table lamps in the prior art can only be used as general lighting or auxiliary lighting, but not as lighting for reading and writing operations, that is, the photometric properties such as illuminance, uniformity and shading cannot meet the national standard "Performance of Reading and Writing Operations Table Lamps". Requirements" (GB / T 9473-2008) related requirements. [0003] Although the partial illumination of most LED desk lamps can meet the lighting requirements for reading and writing operations, the illumination range is small, or the utilization rate of the illumination area is not high, and the uniformity of illumination is not good, resulting in waste of light sources. In order to improve the utilization rate of the...
