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; both side edges of the first transparent light guide body part extend to the direction of the LED light-emitting unit and are mutually parallel; 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; a plurality of beads densely cover the outer side face of the second transparent light guide body part. According to the lens disclosed by the utility model, better illuminance uniformity can be brought, so eye fatigue caused by poor illuminance uniformity is relieved; moreover, a better light spot can be formed.
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.
Also have existing desk lamp irradiated area limited, particularly LED desk lamp, because lampshade structure has dispel the heat and need emission cavity not do darker, is to put down narrow shape substantially, therefore hot spot control is very undesirable, be embodied in scattering serious, illumination center light intensity is inadequate, and edge's intensity is too high.
Utility model content
The technical problems to be solved in the utility model is: propose a kind of LED eye-protecting desk lamp lens that can reach the better illumination uniformity and form better illumination hot spot.
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 towards the inner surface of LED luminescence unit one side curved, 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 provided with the relative draw-in groove that the described lampshade of a pair of confession fastens, the lateral surface of described the second transparent light guide body is arc, the lateral surface of described the second transparent light guide body is densely covered with many fins.
Further, the first transparent light guide body divides towards the inner surface of LED luminescence unit one side and is atomized into frosted shape.
The beneficial effects of the utility model are:
The preferably illumination uniformity can be brought in border of the present utility model, alleviates the kopiopia of using causing because the illumination uniformity is not good.Can form in addition better hot spot.
Brief description of the drawings
Below in conjunction with accompanying drawing, LED eye-protecting desk lamp lens of the present utility model are described further.
Fig. 1 is the structural representation of LED eye-protecting desk lamp lens in embodiment.
Detailed description of the invention
Embodiment
Shown in Fig. 1, the 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, it is 1 curved towards the inner surface of LED luminescence unit one side that the first transparent light guide body divides, and the first transparent light guide body divides 1 dual-side extend and be parallel to each other to LED luminescence unit direction.The first transparent light guide body divides 1 to be atomized into frosted shape towards the inner surface of LED luminescence unit one side.
The lateral surface that the second transparent light guide body divides 2 dual-side place to be provided with a pair of relative draw-in groove 3, the second transparent light guide bodies that fasten for lampshade is arc, and the lateral surface of the second transparent light guide body is densely covered with many fins 4.
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 towards the inner surface of LED luminescence unit one side curved, 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 provided with the relative draw-in groove that the described lampshade of a pair of confession fastens, the lateral surface of described the second transparent light guide body is arc, the lateral surface of described the second transparent light guide body is densely covered with many fins.
2. LED eye-protecting desk lamp lens according to claim 1, is characterized in that: the first transparent light guide body divides towards the inner surface of LED luminescence unit one side and is atomized into frosted shape.
