Problems solved by technology

[0002] Generally speaking, the existing desk lamps all have divergent light, which radiates from the lamp holder to the four sides through the lampshade. If the lampshade is opaque, it is only a directional light in a certain direction, but because the lampshade will refract or reflect or refract the light, thus Some light sources will be wasted, so that the table lamp can only be bright when the power is high. At the same time, if the diffused lights are on all sides, the light source will also be wasted, and the power consumption will be increased virtually.

Embodiment Construction

[0013] The invention will be further described below in conjunction with the accompanying drawings.

[0014] like figure 1 , figure 2 As shown, this dimmable desk lamp includes a lamp holder 1, a lamp holder 2 connected to the lamp holder, and a lamp holder 3 arranged at the other end of the lamp holder. The lamp holder is provided with a lampshade 4, and the lower end of the lampshade is provided with The shade 5; the shade is a folded piece; the inner wall of the lampshade is provided with a reflector 6, and the reflector is a plane mirror.

[0015] When in use, the hood can be folded, compressed and pulled apart, so that the focus point can be adjusted to prevent light from scattering as needed. At the same time, there is a reflector inside the lampshade, which can prevent the light from being refracted and scattered inside the hood. Reduce energy consumption and save energy.

Abstract

The invention discloses a light-adjustable desk lamp which comprises a lamp stand, a lamp bracket and a lamp cap, wherein the lamp bracket is connected with the lamp stand, the lamp cap is arranged at the other end of the lamp bracket, the lamp cap is provided with a lampshade, and the lower end of the lampshade is provided with a light shield. When the light-adjustable desk lamp is used, the light shield can be folded, compressed and opened through pulling, so that the scattering of light can be prevented and the focus point can be adjusted as required; and a reflector is arranged in the lampshade, so that a situation that light is refracted and scattered in the lampshade can be prevented, thereby further reducing the energy consumption and saving the energy.

Description

technical field [0001] The invention relates to a desk lamp, in particular to a dimmable desk lamp. Background technique [0002] Generally speaking, the existing desk lamps all have divergent light, which radiates from the lamp holder to the four sides through the lampshade. If the lampshade is opaque, it is only a directional light in a certain direction, but because the lampshade will refract or reflect or refract the light, thus Some light sources will be wasted, so that when the power is high, the table lamp can be bright. At the same time, if the diffused lights are on all sides, the light source will be wasted, and the power consumption will be increased virtually. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a desk lamp that can adjust the light to generate concentrated light, so that the light source will not be wasted and energy can be saved. [0004] To achieve the above obj...
