Embodiment

[0013] according to figure 1 As shown, the LED eye-protecting desk lamp lens in the present invention includes a desk lamp lampshade and a lens body for fastening on the desk lamp lampshade, and the desk lamp lampshade is provided with an LED light-emitting unit.

[0014] The lens body is composed of a first transparent light guide part 1 and a second transparent light guide part 2 connected together.

[0015] The inner surface of the first transparent light guide part 1 facing the side of the LED light-emitting unit is arc-shaped and densely covered with a plurality of ribs 3, and the two sides of the first transparent light guide part 1 extend toward the direction of the LED light-emitting unit and are parallel to each other. .

[0016] Two sides of the second transparent light guide part 2 are respectively provided with a pair of engaging slots 4 for fastening of the lampshade.

[0017] The outer surface of the second transparent light guide is arc-shaped, and the outer s...

Abstract

The invention relates to an LED eye-protecting table lamp lens which comprises a table lamp cover and a lens body buckled on the table lamp cover. An LED light emitting unit is arranged on the table lamp cover, the lens body is composed of a first transparent light guide body portion and a second transparent light guide body portion which are connected together, the inner surface, facing one side of the LED light emitting unit, of the first transparent light guide body portion is arc-shaped and provided with multiple ribs densely, a pair of opposite clamping grooves allowing a pair of lamp covers to be buckled is arranged at two lateral sides of the second transparent light guide body portion, and the outer side face of the second transparent light guide body portion is arc-shaped and atomized to be frosted. A conventional single-layer lens is designed to be of a similar-bilayer structure, and the inner surface is designed to be arc-shaped, so that refractive angle or transmission distance of light under different irradiating angles in the lens is changed. In addition, the ribs are arranged on the inner wall close to the LED light emitting unit, so that irradiating uniformity is further improved by applying a fresnel lens principle.

Description

technical field [0001] The invention relates to a desk lamp lens, in particular to an LED eye-protecting desk lamp lens. Background technique [0002] "Eye protection table lamp" is mainly composed of two parts: the lamp holder and the lamp. The lamp holder is usually a fluorescent tube or an LED lamp bead; the main electrical components in the lamp are electronic ballasts and switches. The working principle of a "eye protection lamp" on the market: increase the low frequency flicker to high frequency flicker. This eye protection lamp uses a frequency conversion electronic ballast to increase the current frequency from 50Hz to 30-50kHz to make the human eye feel Less flickering, and the use of tri-color phosphors to make the light soft, so as to reduce eye fatigue. The flicker effect is an indicator of all fluorescent tubes: the less noticeable the flicker, the better the lighting. The working principle of another "eye protection lamp" is to change the alternating current...
