Abstract
A ruler with a light-emitting device relates to the stationery, and specifically to a ruler. The ruler comprises a ruler plate and further comprises the light-emitting device. The light-emitting device is arranged on the ruler plate and comprises a power supply, a switch and a luminescent device. The luminescent device is connected to the power supply through the switch, a rechargeable battery is connected to a solar battery, the power supply is the rechargeable battery, the luminescent device is a light emitting diode, one end of the ruler plate is embedded in the light emitting diode, the top end of the light emitting diode faces to the other end of the ruler plate, and the light emitting diode is connected to the rechargeable battery through the switch. The design skillfully makes use of the principles of optics so that one light emitting diode is capable of the lighting the ruler plate completely and the ruler provided with the light-emitting device can be used for measuring lengths in the dark. The ruler has charging function and simple structure, and saves energy resources.
Description
Technical field
The present invention relates to a kind of stationery, be specially a kind of ruler.
Background technology
The ruler of people's use at present can only use in bright occasion, in the dark because people can not read the scale on the ruler, so can not use.
Many times need to measure in the dark length yet people have again, existing like this ruler has just brought inconvenience to use.
Summary of the invention
The object of the present invention is to provide a kind of ruler that light-emitting device is housed, can measure length in the dark.
Technical problem solved by the invention can realize by the following technical solutions:
The ruler of light-emitting device is housed, comprises a chi plate, it is characterized in that:
Also comprise a light-emitting device, described light-emitting device is arranged on the chi plate;
Described light-emitting device comprises a power supply, a switch, a luminescent device, and described luminescent device connects power supply by switch.
Described power supply is a rechargeable battery, luminescent device is a light emitting diode, and described chi plate is transparent chi plate, and an end of chi plate embeds a light emitting diode, the top of light emitting diode is towards the other end of chi plate, and described light emitting diode connects rechargeable battery by switch.
Described rechargeable battery connects a solar cell.When being arranged, light charges to rechargeable battery.
Described luminescent device can also be a fluorescence radiation device.
The present invention adopts transparent chi plate, one end of chi plate embeds a light emitting diode, the top of light emitting diode is towards the other end of chi plate, above-mentioned design has utilized optical principle cleverly, a light emitting diode just can be illuminated chi plate entire body, make the ruler that light-emitting device is housed to measure length in the dark.Has charge function, its simple in structure, energy savings.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
The chi plate 1 that the ruler of light-emitting device is housed with reference to Fig. 1 is transparent chi plate 1, and an end of chi plate 1 embeds light emitting diode 2, as luminescent device, also can adopt the fluorescence radiation device with light emitting diode 2.Rechargeable battery 4 and switch 3 also are equipped with towards the other end of chi plate 1 in the top of light emitting diode 2 on the chi plate 1, described light emitting diode 2 connects rechargeable battery 4 by switch 3.Rechargeable battery 4 connects a solar cell 5.When being arranged, give light rechargeable battery 4 chargings.
The present invention adopts transparent chi plate 1, one end of chi plate 1 embeds a light emitting diode 2, the top of light emitting diode 2 is towards the other end of chi plate 1, above-mentioned design has utilized optical principle cleverly, a light emitting diode 2 just can be illuminated chi plate 1 entire body, make the ruler that light-emitting device is housed to measure length in the dark.It is simple in structure, so only adopt light emitting diode 2 energy savings.Rechargeable battery 4 connects a solar cell 5, the energy savings of can charging voluntarily.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
