Abstract
A LED desk lamp comprises a lampshade, a LED light source and a heat dissipation cover, wherein the lampshade and the upper surface of the heat dissipation cover form an obtuse angle. Disposed at the part where the lampshade is connected with the heat dissipation cover, the LED light source is at least provided with a LED lamp strip therein. The inner side surface of the lampshade is provided with an inclined light guide plate, which at one end contacts the upper surface of the heat dissipation cover and is at the other end connected with a horizontal light guide plate, the other end of which contacts the lower surface of the heat dissipation cover. The angle between the inclined light guide plate and the horizontal light guide plate is an acute angle. The inclined light guide plate is provided with bumps in uniform arrangement thereon. The inclined light guide plate and the horizontal light guide plate are made of transparent plexiglass. The LED desk lamp of the utility model is not only convenient in operation, but also soft in lighting without harm to the eyesight.
Description
Technical field
The utility model relates to a kind of desk lamp, relates in particular to a kind of LED desk lamp, specifically is applicable to workbench, desk or head of a bed illumination.
Background technology
The desk lamp that uses mainly comprises traditional desk lamp and LED desk lamp at present, and wherein the energy consumption of traditional desk lamp is big, flicker is frequent, does not meet energy-conservation with the healthy theme in the world, and existing LED desk lamp, remove magnificent moulding, great majority are that the spot light module that directly utilizes is luminous, are easy to generate dazzle.
The Chinese patent Granted publication number is CN2924285Y, Granted publication day is that the utility model on July 18th, 2007 discloses a kind of LED desk lamp, this kind LED desk lamp is mainly by the lampshade that contains led light source, support, base is formed, lampshade is set up the lenticular body with light uniformization effect that is enough to cover led light source in addition, lenticular body is incorporated into light microscopic face and bright dipping minute surface, light inlet minute surface and bright dipping minute surface system are located at the opposite end of lenticular body respectively, the light inlet minute surface is a convex lens, then be distributed with several lens on the bright dipping minute surface, and these lens are also arranged formation minute surface group, effect by these lens, make light, also can scatter irradiation through luminous intensity distribution through its minute surface outer peripheral areas of bright dipping minute surface.Though the light source that this utility model is sent is comparatively even, radiating effect is better, this lamp illumination is not soft, and its dazzle is heavier to the eyesight injury.
Summary of the invention
The purpose of this utility model be overcome that the LED desk lamp illumination that exists in the prior art is not soft, dazzle is to heavier defective and the problem of eyesight injury, and a kind of LED desk lamp soft, that eyesight do not had injury that throws light on is provided.
For realizing above purpose, technical solution of the present utility model is: a kind of LED desk lamp, this desk lamp comprises lampshade, led light source and heat dissipating housing, described lampshade is fixedlyed connected with heat dissipating housing, described lampshade is a laminated structure, and the angle that the upper surface of lampshade and heat dissipating housing forms is the obtuse angle, and described led light source is arranged on the junction of lampshade and heat dissipating housing, the back of led light source fixedly contacts with heat dissipating housing, and is provided with a LED lamp bar in the led light source at least.
The medial surface of described lampshade is provided with oblique LGP, tiltedly an end of LGP contacts with the upper surface of heat dissipating housing, the other end is connected with horizontal LGP, and the other end of horizontal LGP contacts with the lower surface of heat dissipating housing, and tiltedly the angle between LGP and the horizontal LGP is an acute angle.
The angular range that the upper surface of described lampshade and heat dissipating housing forms is 120 degree-160 degree.
The LED lamp bar that is provided with in the described led light source is two lamp bars that glow color is different.
Described oblique LGP is provided with evenly distributed salient point.
Described salient point is spherical, and evenly distributed according to some formation, flower shape or diverging.
The manufactured materials of described oblique LGP and horizontal LGP is transparent lucite.
The angle that the upper surface of described lampshade and heat dissipating housing forms is 150 degree.
Compared with prior art, the beneficial effects of the utility model are:
Since in a kind of LED desk lamp of the utility model the angle of the upper surface of lampshade and heat dissipating housing formation be the obtuse angle, lampshade is provided with oblique LGP, tiltedly be connected with horizontal LGP on the LGP, and tiltedly LGP and horizontal LGP are transparent pmma material manufacturing, during use, the light that the LED desk lamp sends not is directly to be sent by LED lamp bar, but its light that sends is tiltedly being sent through reflection and after reflecting between LGP and the horizontal LGP again, the light of this moment is softer, free from glare.Therefore the utility model illumination is soft.
2. because the LED lamp bar in a kind of LED desk lamp of the utility model is at least one, can adjust the brightness of every lamp bar by control button, but also can make light softer tiltedly circular salient point being set to strengthen refraction and dispersion effect on the LGP, do not injure eyes.Therefore the utility model luminosity adjustable, eyesight is not had injury.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of oblique LGP in the utility model.
Among the figure: lampshade 1, led light source 2, LED lamp bar 21, heat dissipating housing 3, oblique LGP 4, salient point 41, horizontal LGP 5.
The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment the utility model is described in further detail
Referring to Fig. 1-Fig. 2, a kind of LED desk lamp, this desk lamp comprises lampshade 1, led light source 2 and heat dissipating housing 3, described lampshade 1 is fixedlyed connected with heat dissipating housing 3, described lampshade 1 is a laminated structure, and lampshade 1 is the obtuse angle with the angle of the upper surface formation of heat dissipating housing 3, and described led light source 2 is arranged on the junction of lampshade 1 and heat dissipating housing 3, the back of led light source 2 fixedly contacts with heat dissipating housing 3, and is provided with a LED lamp bar 21 in the led light source 2 at least.
The medial surface of described lampshade 1 is provided with oblique LGP 4, tiltedly an end of LGP 4 contacts with the upper surface of heat dissipating housing 3, the other end is connected with horizontal LGP 5, the other end of horizontal LGP 5 contacts with the lower surface of heat dissipating housing 3, and tiltedly the angle between LGP 4 and the horizontal LGP 5 is an acute angle.
