Abstract
The utility model relates to a palm type film viewer, which comprises a casing, a lamp light source and a power supply unit that are arranged in the casing, a light-conducting plate in the casing, a diffusion paper that is covered on the front surface of the light-conducting plate, a protective sheet that is covered on the diffusion paper, and a light-reflecting paper that is covered on the back surface of the light-conducting plate, wherein, strip-shaped light-reflecting films of concentric circle form, which are also arc-shaped, are coated on the surface of the light-conducting plate, and the light-conducting plate is fixedly installed in the casing by connecting pieces. The lamp light source is arranged at the side end of the light-conducting plate, the power supply unit is installed at one side in the casing, and a power supply is in contact with a lamp through conductive elements. The utility model can be placed in a palm to view slides with uniform luminous efficiency and sharp effect.
Description
The utility model relates to sees sheet device, particularly a kind of viewing equipment that is positioned over the lantern slide watched on the palm.
Existing viewing equipment is generally seen sheet by the light source that is positioned at the below, because light-emitting area is inhomogeneous, watches the lantern slide poor effect; This viewing equipment volume is bigger in addition, and thickness is also thicker.
The purpose of this utility model provides a kind of improved palm-type viewing equipment, and it can be placed on and see sheet on the palm, and its luminescence efficiency is even, and it is clear to see sheet.
A kind of palm-type viewing equipment described in the utility model comprises shell, bulb source of She Zhiing and supply unit in the enclosure, it also comprises the light guide plate that is provided with in the enclosure, the diffusion paper that covers in the front of light guide plate, the screening glass that on diffusion paper, covers, and the reflective sheeting that covers at the back side of light guide plate; The surface-coated of described light guide plate has concentric circles bar shaped reflective membrane, i.e. arc strip reflective membrane, and light guide plate is by the web member fixed installation in the enclosure; Described bulb source is arranged on the side of light guide plate; Described supply unit is installed a side in the enclosure, and power supply contacts with bulb by conducting element.
The utility model is small-sized palm-type, can be placed on and watch lantern slide on the palm, opening power when seeing sheet, light guide plate is under the irradiation of bulb source, and the coated concentric circles bar shaped reflective membrane generation reflection action in light guide plate surface has strengthened luminance brightness thus, make brightness even, it is evenly clear to see sheet.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is a kind of front view of palm-type viewing equipment.
Fig. 2 is the cross-sectional view of above-mentioned viewing equipment.
Fig. 3 is the side view of above-mentioned viewing equipment.
Fig. 4 is the light conducting plate structure synoptic diagram in the above-mentioned viewing equipment.
Referring to Fig. 1 to Fig. 4; a kind of palm-type viewing equipment comprises shell 1; the bulb source 2 and the supply unit 3 that in shell 1, are provided with; the light guide plate 4 that in shell 1, is provided with; the diffusion paper 5 that covers in the front of light guide plate 4; the screening glass 6 that on diffusion paper 5, covers, and the reflective sheeting 7 that covers at the back side of light guide plate 4.
Shell 1 is made up of loam cake 11 and lower cover 12, forms by the fastener member hasp, also can form by securing member is fastening.
The surface-coated of light guide plate 4 has concentric circles bar shaped reflective membrane 41, i.e. arc strip reflective membrane.Light guide plate 4 is fixedly mounted in the shell 1 by web member.
Bulb source 2 is arranged on the side of light guide plate 4, and shown in Fig. 2 is the lower end that is positioned at light guide plate 4.Supply unit 3 is installed in the side in the shell 1, and shown in Fig. 2 is the downside that is positioned at light guide plate 4.
Battery 32, battery contact piece or conducting element and battery cover board 33 that supply unit 3 comprises battery chamber 31, installs in battery chamber 31.As shown in Figure 3, on the supply unit 3 power switch 34 is housed.Battery 32 power supplys contact with bulb 2 by battery contact piece or conducting element.
As shown in Figure 4, the concentric circles bar shaped reflective membrane 41 of light guide plate 4 surface-coated has the branch of thickness and density, be thin and dredge shape at lines near bulb source 2 places, 2 places then are thick and close shape away from bulb source, impel bulb source 2 by light intensity that light guide plate radiated thus, after the thickness and density degree adjustment of lines, and the luminance brightness that reflects has uniform effect, thereby makes that the sight sheet is evenly clear.
When seeing sheet; lantern slide 8 is positioned on the screening glass that the front covered 6 of light guide plate 4; on lantern slide 8, cover layer of transparent film 9 again; also lantern slide 8 can be inserted screening glass 6 that viewing equipments install and the internal layer between the transparent film 9; in the irradiation of bulb source 2 and reflective time of light guide plate 4; and under the reflection action of the reflective sheeting 7 that is covered at the viewing equipment back side, can very clearly watch lantern slide 8.
