Fig. 1 is a kind of schematic top plan view of the reading lamp position of the electronic reader with reading lamp, and Fig. 2, which is one kind, to be had
The schematic side view of the reading lamp position of the electronic reader of reading lamp.Reading lamp 110 is set to the side of electronic reader, including
First light source group and second light source group.Wherein first light source group and second light source group include at least one light source, second light source
The light source of group provides the colour temperature different with when the light source luminescent of first light source group when shining.
Electronic reader further includes light guide section 120 and light source driver module (not showing in Fig. 1 and Fig. 2).Reading lamp 110 is set to
The side of light guide section, the one side opposite with reading lamp 110 of light guide section 120 are the incidence surface 121 of light guide section.It light guide section 120 and reads
There are gaps between reading lamp 110.
Light source driver module include connect first light source group first light source group pin and connect second light source group second
Light source group pin, light source driver module is used to provide operating current to first light source group and second light source group, by adjusting first
The size of the size of the operating current of light source group pin and the operating current of second light source group pin, to provide different reading lamps
Colour temperature.
The above-mentioned electronic reader with reading lamp, including first light source group and second light source group, first light source group use
The colour temperature different from second light source group.The operating current of light source driver module first light source group pin is sized to independently of second
The operating current of light source group pin is adjusted (it should be understood that the operating current size of second light source group pin is equally independent
Adjusted in the operating current of first light source group pin), so as to provide the illumination of different-colour, meet the different need of user
It asks.
In one embodiment, the light source of first light source group and the light source of second light source group are light emitting diode (LED).
In the embodiment shown in fig. 1, reading lamp 110 is set to the bottom side of electronic reader, that is, is designed as that user is hand-held to be made
Used time side directed downwardly.
In the embodiment shown in fig. 1, the winding displacement of electronic reader bottom side blocks the light source at the position, practical to arrange
The line place of blocking is also equipped with the light source of reading lamp 110.
In one embodiment, reading lamp 110 is preceding light formula reading lamp, i.e. light source is set to the front of display screen.
In one embodiment, light guide section 120 is light guide plate, and light guide plate 120 is equipped with multiple light guiding points.When light (example
As reading lamp 110 be emitted light) travel to light guiding points when, light can by light guiding points to all directions reflect and/or reflect, from
And propagation path is changed, and is emitted from the light-emitting surface of light guide plate 120, to which each point light source is changed into area source.
In one embodiment, light guiding points are remoter apart from reading lamp 110, arrangement is more intensive.Please with reference to Fig. 1 and Fig. 3,
Fig. 3 is the light guiding points arrangement schematic diagram of region A and region B in embodiment illustrated in fig. 1.It should be pointed out that in order to enable human eye
It is more preferable to differentiate, it is different in the size of encircled and Fig. 1 in Fig. 3.By gradually increasing leaded light to the direction far from reading lamp 110
The closeness of point can be such that light guide plate 120 is consistent at reading lamp 110 and far from the brightness at reading lamp 110, reach
To the effect of the reading brightness uniformity of entire screen.
In one embodiment, the light source 112 of first light source group and the setting of the light source 114 of second light source group interval, such as Fig. 4
It is shown.
In another embodiment, the light source of reading lamp is arranged at least two rows of, the light source of first light source group and the second light
The light source of source group is located at different rows.In the embodiment shown in fig. 5, the light source 212 of first light source group is arranged in a row, the second light

Face, reflective layer 140 is formed imports light guide plate 120 with the matched reflective surface of curved surface that is in the light, the two cooperation by more light
In.
Referring to Fig. 7, in one embodiment, multiple U-type groove 121a can also be set on the incidence surface of light guide section, passed through
U-type groove 121a is imported after breaing up the light of light source 313 in light guide section, further increases the uniformity of screen intensity.
In the embodiment shown in fig. 8, opposite face 223 of the thickness of light guide plate 220 from incidence surface 221 to incidence surface is gradual
Reduce.The thickness that the structure can utilize 220 both sides of light guide plate different corresponds to different angles, is transmitted in light guide plate 220
Light is via total reflection by light conduction to light extraction inclined-plane 225.
Due to the lightening requirement of electronic reader, the thick side of light guide plate 220 can not be too thick, corresponding inclined-plane
225 inclination angles also cannot be too big, and light source is caused to be projected from inclined-plane 225 with can not be successfully close to the regional area of incidence surface 221,
To which the insufficient blanking bar of illumination can be being formed at incidence surface 221.Fig. 9 is the structural representation of light guide plate in another embodiment
Figure, in this embodiment, the bottom of light guide plate 320 includes the first inclined-plane 327 and the second inclined-plane 325, wherein 327 He of the first inclined-plane
The angle x of top surface 322 is more than the angle y on the second inclined-plane 325 and top surface 322.Due to the gradient higher on the first inclined-plane 327, because
Light at this position can more form total reflection, so as to eliminate the blanking bar near incidence surface.
