The specific embodiment
To shown in Figure 6, ultra-thin eyeshield LED desk lamp is made of base 3 and support 5 and light source base 7 as Fig. 1, on base 3 by support 5 fixed light source(-)holders 7.Base 3 is made of upper base lid 11 and 13 assemblings of lower bottom attic base, is provided with PCB circuit board 15 and base iron plate 17 between base cover 11 and the base disk 13.Lens 19 are posted with respect to the position of circuit board 15 in the outside of base cover 11.Support 5 can be made of by 4 cornue materials of electric wire hollow.Light source base 7 is made of light source flap 21 and 23 up and down.The end face of last light source base lid 21 forms louvre 25, and rear portion central authorities form upper axis trepanning 27.Following lamp combination cover 23 is fixed on support 5 upper ends after assembling with last lamp combination cover 21, and end face forms bigger perforation cavity 29, and rear portion central authorities form lower shaft trepanning 31.
In the present embodiment, the inside of light source base 7 is provided with fin 33, LGP 35, LED substrate 37, and fin 33 is the rectangle aluminium, and descending formation assembling end 39 is extended at two ends.Post the assembling that below fin 33, contacts of reflection paster 41 above the LGP 35.LGP 35 is the transparent acrylic board of rectangle of specific thicknesses.LGP 35 is after one side is handled with the whitewash silk-screen, to form with the bonding reflection paster of bonding agent P2 at printing surface.By silk-screen whitewash layer P1, stick reflection paster 41 again on the LGP 35, the very fine space layer of middle generation can disperse to enter the anti-phenomenon of part deepening here of light.Certainly, reflection paster 41 also will equally with whitewash layer P1 will be used white, and bonding agent P2 also wants white.LED substrate 37 is equipped with many LED lamps 43 by length direction, is assemblied in the inner face of the assembling end of fin 33 with high temperature resistant paster.At this moment, each LED lamp 43 sticks on the relevant position of LGP 35 both sides.
In the present embodiment, LED lamp 43 is to be lighted and the LED of the redness of the specific quantity of adjustable color temperature degree and color amount, green, blueness, white constitutes by control part.It is the LED lamp of each redness, green, blueness, send pwm control signal by the pattern control of control part and light and regulate color temperature, the pattern control of white led lamps by control part is sent pwm control signal and is lighted and can regulate brightness, embodies multimodal illuminating effects such as mode of learning, perceptual model, atmosphere pattern.In the following corresponding position of lamp combination cover 23 through holes, be equipped with diaphragm 47, the filter coating 49 that has the refrangible dispersed light to penetrate between LGP 35 and the diaphragm 47.
At this moment, be equipped with axle sleeve 69 in axle housing 55 and 57 the axle sleeve hole up and down 63 and 65 up and down, opposite side serve as reasons lamp combination cover 21 and 23 axle sleeve holes up and down 27 and 31 that form up and down, order lamp combination 21 and 23 up and down can rotated in the axle housing 55 and 57 up and down.
At last, light source base 7 is assemblied in the upper end of support 5 by sloping shaft structure 8, constitutes 2 ball and socket structures based on the folk prescription of support 5 to the skewed action of action of hinge shape and specific direction.Revolute axes configuration 9 is to be inserted into support 5 by following axis body 71 to fix, and following axis body 71 is made as one with the thrust collar 73 of lower end central authorities, forms hollow.
Following axis body 71 is connected with rotary body 77 usefulness screws 75, and rotary body 77 forms axle bed 79 with respect to the both sides, top of thrust collar 73 both sides, and the installation opening 85 by base 11 forms rotation.Be the two ends that following axle bed 79 that the both sides up and down of rotary body 77 form is inserted into down the thrust collar 73 of axis body 71, put into the position of pad W after, by axle bed 79 and thrust collar 73 down, with screw 75 and nut 81 fixedly rotary body 77 and following axis body 71.
At this moment, torque spring S is equipped with in the inboard of thrust collar 73, and the one end is located at down the hollow inside of axis body 71, and the other end is in a side of rotary body 77, gives support 5 specific restoring force.The rotary sleeve 83 of rotary body 77 usefulness base cover 11 inside is fixed on the installation opening 85, realizes the purpose that support 5 rotates at seating plane.To add pad W between rotary body 77 and the base cover 11.Support 5 is installed on the base 3 by revolute axes configuration 9, constitutes 2 ball and socket structures based on the folk prescription of the support 5 of base 3 to the spinning movement of action of hinge shape and special angle.
With above-mentioned the same; the light source base 7 that constitutes LED desk lamp 1 is equipped with the LGP 35 that one side is posted reflection paster 41; corresponding position, both sides disposes the LED lamp 43 of multiple color by length direction; thereby form the indirect type illumination; high light can directly not injected user's the visual field, for preventing flash of light, vision protection and having improved learning efficiency big beneficial effect.Particularly used the LED 43 of multiple color to be light source, provide high efficiency multiple mode of learning by regulating color temperature and brightness, throwing light on by the perception of multicolour provides psychology stable result of treatment.
LED lamp 43 is configured in the both sides of LGP 35, make the thickness of whole light source base 7 reduce greatly, also have light source base 7 to be contained on the support 5 by sloping shaft structure 8, constitute 2 ball and socket structures, support 5 is contained on the base 3 by revolute axes configuration 9, constitute 2 ball and socket structures, the user can be regulated the position multi-angle of light source base 7, demonstrate out the atmosphere that multi-angle is used.Being light source base 7 on sloping shaft structure 8 times, serves as mainly to do the action of hinge shape by fore-and-aft direction with support 5, does tilting by axle sleeve 69 in addition and rotates; Support 5 is revolute axes configuration 9 times, serves as mainly to do the action of hinge shape by fore-and-aft direction with base 3, and can make the spinning movement of special angle.
