Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The object of the present invention is to provide a kind of LED tablecloths that luminescent color varies with temperature, to solve in the prior art one
Kind of LED tablecloths can only send out a kind of color or several colors and color and the constant problem of intensity.
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, below in conjunction with the accompanying drawings and specific real
Applying mode, the present invention is described in further detail.
As shown in Figure 1, the LED tablecloths that luminescent color of the present invention varies with temperature, include connecting successively inside conventional tablecloth
Human body induction module (1), temperature detecting module (2), temperature-coloured light selecting module (3) and the LED drive module (4) connect, human body
Induction module is predominantly detected to take a seat either with or without people and be had dinner, and is placed in the edge that tablecloth hangs down, when detect someone take a seat have dinner when,
Human body induction module (1) works with regard to start-up temperature detection module (2).Temperature detecting module (2) mainly utilizes the temperature built in tablecloth
It spends sensor and detects eating surroundings temperature, general temperature sensor is no less than 4, can be placed in four angles that tablecloth hangs down, temperature
Degree by degree Celsius as unit of, the arithmetic mean of instantaneous value of the temperature value that several temperature sensors detect is final eating surroundings temperature
Degree, and the eating surroundings temperature detected is sent to temperature-coloured light selecting module (3), it detects again at regular intervals just
Meal environment temperature, the interval time detected twice can be manually set.
As shown in Fig. 2, being prefixed temperature-temperature grade in temperature-coloured light selecting module corresponds to table.Temperature-temperature grade
The principle that corresponding table is set up is that temperature is higher, and temperature grade is also bigger.In view of the range of room temperature, setting eating surroundings temperature t
Less than 14 degrees Celsius, corresponding temperature grade is 1；Eating surroundings temperature t is greater than or equal to 30 degrees Celsius, corresponding temperature grade
It is 10.With 2 degrees Celsius of interval for 1 temperature grade in 14 degrees Celsius and 30 degree Celsius ranges.
As shown in figure 3, being prefixed temperature grade-coloured light in temperature-coloured light selecting module corresponds to table.Temperature grade-coloured light
The principle that corresponding table is set up is that the high corresponding coloured light of temperature grade is cool colour light, and the low corresponding coloured light of temperature grade is warm colour light,
Simultaneously it is also contemplated that required coloured light is appetitive coloured light.When temperature grade is 1-10, corresponding coloured light is respectively red, powder
Red, orange, orange, yellow, dark brown, grey, white, green and blue.Red, pink, orange, orange and yellow are
Warm colour light, dark brown, grey, white, green and blue are cool colour light.Red is most to hook the color of people's appetite.Pink is
Gentle best annotation, can make the taste of food become more fragrant and more sweet.Orange and orange makes one generation vigor, induces appetite.It is yellow
Color is the color to stimulate appetite.Dark brown makes us easy to be happy and auspicious；Grey makes us amiable.White gives the feeling of people's cleaning；Green enables
People is happy；Blue makes us quiet and tastefully laid out quiet.These cool colour light make eater be in a cheerful frame of mind in the relatively high environment of temperature, in turn
Promote appetite.
