Abstract
The utility model relates to a light-emitting blackboard, which comprises a blackboard face (1). The blackboard face (1) is transparent ground glass; the back of the blackboard face (1) is provided with a light-emitting tube (2); and the light-emitting tube (2) is connected with a power socket (3). In the light-emitting blackboard, the back of the blackboard face is provided with the light-emitting tube and the blackboard face is the transparent ground glass, therefore, writing is convenient; light emitted from the light-emitting tube can effectively penetrate through the blackboard face; sharp contrast is formed between written characters and the blackboard face. The light-emitting blackboard is suitable for all weathers and is beneficial to protecting the vision of students.
Description
Technical field
The utility model relates to a kind of blackboard, relates in particular to a kind of luminous blackboard.
Background technology
The blackboard that uses is when rainy weather at present, light will be very dark, it is more painstaking to make the student look at the blackboard, even driving fluorescent lamp also can cause reflective, the student who makes the blackboard both sides is owing to the minute surface reflection of blackboard does not see, serious meeting influences middle school student's eyesight, lacks the luminous blackboard of a kind of effective energy and solves this deficiency.
Summary of the invention
The purpose of this utility model is at having defective and the deficiency that blackboard can not be luminous now, now provide a kind of simple in structure, cheap, luminous very easily blackboard being installed.
For achieving the above object, technical solution of the present utility model is: luminous blackboard comprises: blackboard surface is characterized in that: described blackboard surface is the frosted glass of printing opacity, and the back side of blackboard surface is equipped with luminous tube, and luminous tube is connected with attaching plug.
Described luminous tube also is connected with brightness regulator.
The beneficial effects of the utility model are: the back side at blackboard surface is equipped with luminous tube, and blackboard surface is the frosted glass of printing opacity, conveniently writes; the luminous energy that luminous tube sends sees through blackboard surface effectively; word and the blackboard surface write are with distinct contrast, are suitable for any weather and use, and help to protect student's eyesight.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: blackboard surface 1, luminous tube 2, attaching plug 3, brightness regulator 4.
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, luminous blackboard of the present utility model comprises: blackboard surface 1, and described blackboard surface 1 is the frosted glass of printing opacity, and the back side of blackboard surface 1 is equipped with luminous tube 2, and luminous tube 2 is connected with attaching plug 3.
Described luminous tube 2 also is connected with brightness regulator 4.
Blackboard surface 1 is the frosted glass of printing opacity, and the back side of blackboard surface 1 is equipped with luminous tube 2, can send soft light after luminous tube 2 energisings, and luminous tube 2 also is connected with brightness regulator 4, is convenient to regulate the brightness of luminous tube 2.Blackboard surface is the frosted glass of printing opacity, conveniently writes, and the luminous energy that luminous tube sends sees through blackboard surface effectively, and word and the blackboard surface write are with distinct contrast, help to protect student's eyesight.
Claims (2)
1. luminous blackboard comprises: blackboard surface (1) is characterized in that: described blackboard surface (1) is the frosted glass of printing opacity, and the back side of blackboard surface (1) is equipped with luminous tube (2), and luminous tube (2) is connected with attaching plug (3).
2. luminous blackboard according to claim 1 is characterized in that: described luminous tube (2) also is connected with brightness regulator (4).
