Abstract
The utility model relates to a light-emitting diode (LED) light emitting display liquidometer. An inner layer glass tube is coated with a fluorescence reflective layer. The upper end and the lower end of an outer layer glass tube and the upper end and the lower end of the inner layer glass tube are respectively provided with a lower LED luminous light and an upper LED luminous light. Through the up-and-down variation of observed liquid inside the inner layer glass tube, irradiance of the lower LED luminous lights and irradiance of the upper LED luminous lights react with each other so that the liquid level of the observed liquid is displayed, and the LED light emitting display liquidometer is simple, audio-visual, eye-catching and especially conducive to observation under the circumstances of nighttime and poor light rays.
Description
Technical field
The utility model is a kind of LED luminescence display liquid level gauge, belongs to electronic technology field, and the interaction of the LED illuminator by the fluorescent reflector layer on the internal layer glass-tube and glass-tube upper and lower side shows liquid level.
Background technology
Present liquid level gauge is all to show with change color, also not with the luminous liquid level gauge structure directly perceived of initiatively shining the double glazing reflective display of LED.
The utility model content
The purpose of this utility model is to provide a kind of LED luminescence display liquid level gauge, by realize the demonstration directly perceived to liquid level with the LED illuminator.
Its objective is such realization, a kind of LED luminescence display liquid level gauge is comprised of outer layer glass tube, inner layer glass tube, fluorescence reflector layer, observed liquid, lower LED luminous lighting, upper LED luminous lighting; Scribble the fluorescence reflector layer on inner layer glass tube, at the upper and lower side of outer layer glass tube and inner layer glass tube, lower LED luminous lighting and upper LED luminous lighting are housed respectively, when being communicated with container, observed liquid will change in inner layer glass tube up and down.
Effect has occured and has expressed the liquid level of observed liquid in the change up and down by observed liquid in inner layer glass tube, lower LED luminous lighting and upper LED luminous lighting luminous, is conducive to observe in the situation of night and light difference.
Description of drawings
Concrete structure of the present utility model is provided by following examples and accompanying drawing:
Fig. 1, be a kind of LED luminescence display of the utility model liquid level gauge structural representation.
In Fig. 1,1, outer layer glass tube, 2, inner layer glass tube, 3, fluorescence reflector layer 4, observed liquid, 5, lower LED luminous lighting, 6, upper LED luminous lighting.
Embodiment
Describe the specific works situation that the utility model proposes in detail below in conjunction with Fig. 1, effect by upper LED luminous lighting 6 and lower LED luminous lighting 5 and fluorescence reflector layer 3, just demonstrate the place liquid level of observed liquid 4, and the double-decker of outer layer glass tube 1 and inner layer glass tube 2 is mainly to realize application fluorescence reflector layer 3 on inner layer glass tube 2.
Claims (1)
