Abstract
The utility model relates to an LED (light-emitting diode) eye-protection table lamp lens, which comprises a table lampshade and a lens body buckled onto the table lampshade, wherein the table lampshade is provided with an LED light-emitting unit; the lens body consists of a first transparent light guide body part and a second transparent light guide body part which are connected together; the inner surface, facing towards one side of the LED light-emitting unit, of the first transparent light guide body part is arc-shaped and is densely covered with a plurality of beads; a pair of opposite necks used for buckling the lampshade is arranged at both side edges of the second transparent light guide body part; the outer side face of the second transparent light guide body part is arc-shaped; the outer side face of the second transparent light guide body part is atomized into a frosted face. According to the LED eye-protection table lamp lens disclosed by the utility model, a traditional single-layer lens is designed into a lens with a bilayer-like structure, and the inner surface of the lens is designed into an arc, so refraction angles or the transmission distances of light rays in the lens under different irradiation angles are changed. Moreover, the beads are arranged near the inner wall of the LED light-emitting unit, and illuminance uniformity is further enhanced by applying the Fresnel lens principle.
Description
Technical field
The utility model relates to a kind of desk lamp lens, is specifically related to a kind of LED eye-protecting desk lamp lens.
Background technology
" eye-protecting desk lamp " is mainly made up of lamp holder and light fixture two parts.Lamp holder is fluorescent tube or LED lamp pearl normally; Major electrical equipment element in light fixture is electric ballast and switch.The operation principle of a kind of " eye-protecting lamp " on the bustling noise of a market: low stroboscopic is increased to high stroboscopic, this eye-protecting lamp adopts frequency conversion electronic ballast, power frequency is increased to 30-50kHz by 50Hz so that human eye perceives less than stroboscopic, and adopt three primary colors fluorescent powder, make light soft, alleviate asthenopia with this.Stroboscopic effect is an index of all fluorescent tubes: stroboscopic is more not obvious, and illuminating effect is better.The operation principle of another kind of " eye-protecting lamp ": alternating current is first become to direct current, light a lamp with direct current, just reach real without stroboscopic, greatly remitting vision fatigue.And there is no an electromagnetic radiation.
But also lack at present from the eye-protecting desk lamp improving and regulating illumination uniformity of brightness is set about, because intensity of illumination also can be alleviated and use kopiopia uniformly.
Utility model content
The technical problems to be solved in the utility model is: propose a kind of improvement and the LED eye-protecting desk lamp lens of regulating illumination uniformity of brightness.
The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of LED eye-protecting desk lamp lens, comprise table lamp lampshade and for being fastened on the lens body on table lamp lampshade, described table lamp lampshade is provided with LED luminescence unit, described lens body is to be divided with the second transparent light guide body and divided and form by the first transparent light guide body linking together, the first transparent light guide body divides the inner surface towards LED luminescence unit one side curved and be densely covered with many fins, the dual-side that the first transparent light guide body divides extends and is parallel to each other to LED luminescence unit direction, the dual-side place that described the second transparent light guide body divides is respectively equipped with the draw-in groove that the described lampshade of a pair of confession fastens.
Further, the lateral surface of described the second transparent light guide body is arc, and the lateral surface of described the second transparent light guide body is atomized into frosted shape.
The beneficial effects of the utility model are:
The utility model is by traditional individual layer Lens Design is become to have class double-decker, and inner surface is designed to arc, changed refraction angle or the transmission range of light in lens under different irradiating angles.
Be provided with many fins near on the inwall of LED luminescence unit in addition, using Fresnel Lenses principle further to strengthen the irradiation uniformity.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, LED eye-protecting desk lamp lens of the present utility model are described further.
Fig. 1 is the LED eye-protecting desk lamp lens arrangement schematic diagram in embodiment.
The specific embodiment
Embodiment
Shown in Fig. 1, LED eye-protecting desk lamp lens in the utility model, comprise table lamp lampshade and for being fastened on the lens body on table lamp lampshade, table lamp lampshade is provided with LED luminescence unit.
Lens body be by the first transparent light guide body linking together divide 1 and second transparent light guide body divide 2 to form.
The first transparent light guide body divides 1 inner surface towards LED luminescence unit one side curved and be densely covered with many fins 3, the first transparent light guide bodies and divide 1 dual-side extend and be parallel to each other to LED luminescence unit direction.
The second transparent light guide body divides 2 dual-side place to be respectively equipped with a pair of draw-in groove 4 fastening for lampshade.
The lateral surface of the second transparent light guide body is arc, and the lateral surface of the second transparent light guide body is atomized into frosted shape.
The above-described embodiment that is not limited to of the present utility model, all employings are equal to replaces the technical scheme forming, and all drops in the protection domain of the utility model requirement.
Claims (2)
1. LED eye-protecting desk lamp lens, comprise table lamp lampshade and for being fastened on the lens body on table lamp lampshade, described table lamp lampshade is provided with LED luminescence unit, it is characterized in that: described lens body is to be divided with the second transparent light guide body and divided and form by the first transparent light guide body linking together, the first transparent light guide body divides the inner surface towards LED luminescence unit one side curved and be densely covered with many fins, the dual-side that the first transparent light guide body divides extends and is parallel to each other to LED luminescence unit direction, the dual-side place that described the second transparent light guide body divides is respectively equipped with the draw-in groove that the described lampshade of a pair of confession fastens.
