Abstract
The utility model relates to a blue and yellow LED adjustable color temperature lamp which comprises a main control circuit and a plurality of LED lamps and is characterized in that the LED lamps include two colors, i.e. blue and yellow; the main control circuit controls the brightness values of the LED lamps, so as to enable the LED lamps to obtain different color temperature values through colormixture. The utility model can be not only used for improving outdoor lighting quality to save energy, but also applied indoors so as to adjust high-quality lighting color according to the requirements of users.
Description
Technical field
The utility model relates to a kind of indigo plant, yellow LED adjustable color temperature lamp.
Background technology
The traffic safety transportation belongs to the extremely sensitive industry of meteorology, and it is quick that it is pursued, efficient, safety, and punctual target will be subjected to the restriction of meteorologic factor to a great extent.Along with national economy and fast development of urbanization, the traffic safety security problem that is caused by meteorological condition has become a key factor that influences economic development.Show that according to statistics low visibility weather phenomenon such as dense fog had reached unprecedented degree to the influence harm of traffic and the disaster that causes in recent years, had become the key factor that influences traffic safety.Therefore the raising of road lighting quality needs to be resolved hurrily.Show that according to the study atmospheric visibility has obvious diurnal variation and variation characteristic month by month.With regard to diurnal variation, visibility was with 14 o'clock maximums, but minimum the period occurs not necessarily.For seasonal variations, annual with summer the atmospheric visibility situation best.No matter be seasonal variations or diurnal variation, the atmospheric visibility on the road is the coefficient result of meteorological element and air pollutants.Because of in the mesopic vision level, high color rendering index (CRI), under the light illumination of high colour temperature, human eye is than the easier things of distinguishing of low colour temperature environment, and the high colour temperature section of while led light source is than low colour temperature section luminous efficiency height.But the wavelength of gold-tinted is long, is difficult for being scattered, and also is difficult for refraction, and penetration power is strong, and visual range is far away.Therefore, comprehensive above information, if, can effectively improve the road lighting quality according to coming intelligence to regulate the colour temperature of white light by the difference of induction atmospheric visibility, the road improvement traffic safety, the while reasonable disposition energy, it is energy-conservation really to embody LED.In addition, find that according to the study lighting colour is also close with people's psychic relation, for example: low colour temperature: colour temperature is below 3300K, and the photochromic red partially warm sensation of giving sets off steady atmosphere; Middle colour temperature: colour temperature is at 3000～6000K, and this colour temperature makes blueness have refrigerant sense, gives frank sensation; High colour temperature: colour temperature is more than 6000K, and photochromic inclined to one side indigo plant is given chilly sensation.Yet existing LED lamp does not reach this effect as indoor illumination.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this utility model provides a kind of indigo plant, yellow LED adjustable color temperature lamp, and it not only can be used for improving outdoor quality of lighting, energy savings, and can be applicable to indoor, according to human needs, adjust high-quality lighting colour.
The utility model is to realize like this, a kind of indigo plant, yellow LED adjustable color temperature lamp, comprise governor circuit and several LED lamps, it is characterized in that: described several LED lamps comprise indigo plant, yellow two kinds of colors, described governor circuit is realized the control of the brightness value of several LED lamps is made it to obtain different color temperature values through colour mixture.
The utility model is simple in structure, good energy-conserving effect, and cost is low, has market value preferably.
Description of drawings
Fig. 1 is the schematic block circuit diagram of the utility model embodiment one.
Fig. 2 is the circuit theory diagrams of the utility model embodiment two.
Fig. 3 is system's control flow chart of the utility model embodiment two.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in Figure 1, the utility model discloses a kind of indigo plant, yellow LED adjustable color temperature lamp, comprise governor circuit and several LED lamps, it is characterized in that: described several LED lamps comprise indigo plant, yellow two kinds of colors, described governor circuit is realized the control of the brightness value of several LED lamps is made it to obtain different color temperature values through colour mixture.
When the utility model is applied to when indoor, the user can regulate by governor circuit and be fit to user's color temperature value of mood at that time, thereby realizes indoor high-quality lighting colour.Preferable, governor circuit adopts the pwm control circuit of chip microcontroller in the present embodiment, and it produces corresponding PWM value signal control LED lamp.
When the utility model is applied to outdoor lighting, circuit diagram as shown in Figure 2, the system master circuit adopts the pwm control circuit of chip microcontroller, it is by the visibility signal of the surrounding enviroment of analysis, processes sensor collection, produce the brightness value of corresponding PWM value signal control LED lamp, make it to obtain different color temperature values through colour mixture.For example, when low, colour temperature is warm white in the atmospheric visibility grade; When being medium, colour temperature is positive white light in the atmospheric visibility grade; When being high, colour temperature is cold white light in the atmospheric visibility grade.
What deserves to be mentioned is that the lamp of described indigo plant, yellow two kinds of colors is divided into two links respectively by governor circuit control by color, described two links are made up of blue led lamp serial or parallel connection for one, are made up of the yellow LED lamp serial or parallel connection for one.
In the present embodiment, system further comprises mu balanced circuit, and power supply is system's power supply by mu balanced circuit, has guaranteed the reliable and stable of power supply.The control flow of system sees also Fig. 3.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
