Abstract
The utility model relates to a carved glass lamp picture which is composed of a picture carved on glass, a reflecting cover which is connected with the bottom edge of the glass, light sources which are arranged in the bottom edge of the glass and a closed hollow cavity of the reflecting cover, and reflecting layers which are arranged on the upper surface of the glass and both side surfaces. The utility model has an illuminating function and has the advantages of good appreciative and decorative effects, etc.
Description
A kind of engraved glass lamp is drawn.
Existing engraved glass is drawn and can only be viewed and admired by day, and does not have illumination functions.
The engraved glass lamp that the novel purpose of this reality is to provide a kind of daytime and night can both view and admire, have illumination functions and good decorating effect is drawn.
The purpose of this utility model is realized by following technical scheme: a kind of engraved glass lamp is drawn, has picture at engraving on glass, its special character is that the base of glass is connected with reflection shield, in the enclosed cavity of glass base and reflection shield, settle light source, on glass, be provided with reflector layer with two sides.
Engraved glass lamp of the present utility model is drawn with existing engraved glass picture and is compared, because the utility model is according to geometric optical theory, the glass base of drawing at engraved glass is connected with reflection shield, in the enclosed cavity of glass base and reflection shield, settle light source, on glass, be provided with the structure of reflector layer with two sides, light only is mapped to drawing of engraving and could folds into the optically thinner medium air from the glass medium, draws thereby show alight.Can both view and admire picture with night by day, the lamp at night is drawn more create an aesthetic feeling, and has advantages such as illumination functions, good decorating effect.
The utility model is described in further detail to utilize embodiment shown in the drawings below.
The perspective view that Fig. 1 draws for the engraved glass lamp.
Fig. 2 is the light schematic diagram that does not have carving picture on the glass (1).
The light schematic diagram that Fig. 3 draws for the engraved glass lamp.
With reference to Fig. 1, go up carving picture (2) at glass (1), the base of glass (1) is connected with reflection shield (3), and reflection shield (3) is the arc cover, can adopt metal or plastic or other material to make, reflectorized materials such as coating mercury or tin platinum in the cover.Settle light source (4) in the enclosed cavity that the base and the arc reflection shield (3) of glass (1) connects to form, light source (4) is fluorescent lamp or other electric light.Be provided with reflector layer (5) with two sides on glass (1), reflector layer (5) is Xu's layers such as mercury coating or tin platinum.Also can be on glass (1), the side is provided with light source (4), with reflector layer (5) light source (4) sealing is realized.
With reference to Fig. 2, in the glass medium, when light by E
2Point directive E
1When point is formed into firing angle r at the base of glass BB ', and according to glass performance, when r equaled 42 °, light will be along the base of glass by E
1To penetrating, when having only incidence angle r less than 42 °, light just can leave the glass medium and enter in the optically thinner medium air point to B, and at this moment, light is by E
1Point reflects to the E point.According to path reversal principal, light is by E point directive E
1Point, light is by E
1The point refraction is to the E of glass stile A ' B '
2The point.Because glass base BB ' is perpendicular to glass stile A ' B ', so, by E
1Point is mapped to E
2The incidence angle of light on glass stile A ' B ' of point is greater than 48 °.If incidence angle is greater than 42 ° of critical angles, and light can not enter the optically thinner medium air from glass stile A ' B ', so light is by E
2The point total reflection is to the E of AA '
3Point is at E
3Point is at E
3The incidence angle r that forms
3Less than 42 °, can leave glass AA ' limit by principle light and enter in the optically thinner medium air.But owing to be provided with reflector layer on AA ' limit, light can only be reflected in the glass medium, by E
3Point is mapped to the E on AB limit
4Point is at E
4The incidence angle r that point forms
4Still greater than 42 °, by E
4Point is totally reflected to the E of base BB ' again
5Point is at E
5Point incidence angle r
5Less than 42 °, light can leave glass base BB ' and be refracted in the optically thinner medium air.But owing to be provided with reflection shield below end BB ', light also can only also be reflected in the glass medium.
With reference to Fig. 3, behind the carving picture of the front of glass, because of the overwhelming majority of the curved side that forms picture all is not parallel to the front of glass, so, when light by E point directive E
1And be refracted to E
2During point, incidence angle r must be total reflection greater than 48 °, and is mapped to E
3Point is at E
3Though the incidence angle that point forms can reflect the glass medium less than 42 ° of light and since glass above scribble reflector layer, so, light be forced to and reflected back glass medium in, have only light to reach the E of carving picture
4When point, because the change of incidence angle, when incidence angle during less than 42 °, light just can leave the E of glass medium to front surface A ' B ' limit of glass
5Direction reflect away.When at E
4The incidence angle of point is during still greater than 42 °, and light will be to E
6The direction total reflection of point is at E
6The incidence angle that point forms is less than 42 °, and light also can leave the glass medium from the reverse side AB limit of glass, folds in the optically thinner medium air.Same principle, other light of light source also only is mapped on the carving picture, has changed incidence angle, when incidence angle during less than 42 °, just can reflect the glass medium.Here it is night, and after the some bright light source, Glass lamp is drawn the cause that can throw light on, can manifest again picture.
Claims (1)
1, a kind of engraved glass lamp is drawn, by the picture (2) of going up engraving at glass (1), it is characterized in that: the base of glass (1) is connected with reflection shield (3), in the enclosed cavity of the base of glass (1) and reflection shield (3), settle light source (4), on glass (1) and two sides be provided with reflector layer (5) and form.
