Embodiment 1

[0024] Such as figure 1 As shown, the desktop LED lamp based on adjusting light intensity includes a lampshade 5, the lampshade 5 is a closed structure, the bottom of the lampshade 5 is provided with a base 6, and the outer wall of the lampshade 5 is provided with an annular groove. The annular groove is provided with a number of light-transmitting holes, and the outside of the annular groove is covered with a light shield 3, and the light shield 3 is provided with a through hole 4 corresponding to the light-transmitting hole. Relative movement can occur between the annular grooves.

Embodiment 2

[0026] Such as figure 1 As shown, this embodiment is based on Embodiment 1, the light-transmitting hole is a rectangular hole, and the rectangular hole is arranged along the circumferential direction of the annular groove ring, and the size of the through-hole 4 is consistent with the light-transmitting hole; the lampshade The top of the 5 is provided with a light-transmitting hole I, and also includes a cover body 2 that cooperates with the lampshade 5. The cover body 2 is provided with a through hole I1 corresponding to the light-transmitting hole I; the cover body 2 can be screwed. On the top of the lampshade 5 ; the shade 3 is a belt-shaped structure, and the two ends of the belt-shaped structure are bonded by magic tape to form a ring structure.

Abstract

The invention discloses a table type LED lamp based on light intensity regulation. The table type LED lamp comprises a lampshade, wherein the lampshade is of a sealed type structure; a pedestal is arranged on the bottom of the lampshade; a ring-shaped groove is formed in the outer wall of the lampshade; a plurality of light transmission holes are formed in the ring-shaped groove; a light shielding cover sleeves outside the ring-shaped groove; through holes which correspond to the light transmission holes are formed in the light shielding cover; and the light shielding cover and the ring-shaped groove can generate relative movement. The light shielding cover can peripherally rotate around the lampshade, the light shielding cover and the ring-shaped groove generate relative displacement, i.e., the through holes and the light transmission holes generate relative displacement, so that the covering area of the light transmission holes by the light shielding cover is changed, regulation on sizes of the light transmission holes is realized, and regulation on brightness of the LED lamp is realized. The table type LED lamp solves the problem that brightness of an existing LED lamp cannot be regulated.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to a desktop LED lamp based on adjusting light intensity. Background technique [0002] Light-emitting diode lamps, also known as LED lamps, refer to appliances that can transmit light, distribute and change the light distribution of LED light sources, including all parts and components required to fix and protect LED light sources except for LED light sources, as well as connections to power sources Required wiring accessories. With its technical characteristics of high efficiency, energy saving, safety, longevity, small size, and clear light, LED lamps are becoming the main product in the new generation lighting market, and they are powerfully driving the rapid development of the environmental protection and energy saving industry. [0003] In order to adapt to different needs, the light of LED lamps needs to be adjustable. However, at present, the brightness of existing LED l...
