The colour temperature difference of lighting source can produce different atmosphere effect, as:
Colour temperature＞5000K; People's visual experience: the white that (refrigerant) is blue partially; Atmosphere effect: chilly;
Colour temperature 3300-5000K; People's visual experience: (neutrality) warm white; Atmosphere effect: frankness;
Colour temperature＜3300K; People's visual experience: the yellow white of (warm) band; Atmosphere effect: steady.
As can be seen from the above: the high more color of colour temperature can inclined to one side more blueness, and the low more color of colour temperature can inclined to one side more yellow, and we can utilize the different colour temperature of lighting source, create different environments.At present, used LED in the LED illuminating lamp of the white light LEDs light emitting diode on the market and the overwhelming majority, its colour temperature is all greater than 5000K, and the visual experience of giving the people is blue partially white, produces chilly atmosphere.Blue concerning people's psychological application, it belongs to chilly and passive color.And in the actual life, people often more need and like, colour temperature photochromic, warm near incandescent lamp to illuminate and beautify our environment less than the low colour temperature illuminating lamp of 5000K.
The utility model content
The LED illuminating lamp that provides a kind of colour temperature adjustable is provided the purpose of this utility model, to overcome the defective that existing LED illuminating lamp sends single inclined to one side blue and white light, the lighting environment different according to the user built warm, steady lighting atmosphere, satisfies the demand of different application environment.
The technical solution of the utility model is: the LED illuminating lamp that colour temperature is adjustable, include shell body, equal tabula rasa and printed circuit board (PCB), it is characterized in that, to shell body one side three-terminal voltage regulator IC1, three-terminal voltage regulator IC2, current limliting sample resistance R1, current limliting sample resistance R2 are housed on printed circuit board (PCB), low colour temperature, warm-toned light emitting diode and white light emitting diode are equipped with in the another side; Described low colour temperature, warm-toned light emitting diode and white light emitting diode intersection are evenly arranged on the printed circuit board (PCB), and are powered respectively by independent constant-current source, and described each constant-current source is made up of three-terminal voltage regulator and current limliting sample resistance; Wherein, between constant-current source that hangs down colour temperature, the power supply of warm-toned light emitting diode and dc voltage electrode end, be provided with gauge tap K.
Described low colour temperature, warm-toned light emitting diode are Yellow light emitting diode, orange light-emitting diode, red light-emitting diode or its combination.
Described equal tabula rasa is made by semi-transparent glass, acrylic or plastic material.
Good effect of the present utility model is:
1) in the illumination lamp plate of forming by white light LEDs, evenly adds low colour temperature, warm-toned light emitting diode, as: yellow, orange, red light emitting diodes, luminous by these low colour temperature light emitting diodes, the illuminating lamp that remedies and correct original white light LEDs composition sends the drawback of inclined to one side blue and white light, the lighting environment different according to the user, build warm, steady lighting atmosphere, satisfy the demand of different application environment.
2) the illumination work face under the LED of the different-colour luminous projection simultaneously can produce uneven color spot, it is evenly distributed that the utility model adopts the illuminating lamp onboard led to intersect, and then the method that installs the equal tabula rasa of being made by semi transparent material in the place ahead of LED additional reduces and eliminates this phenomenon.
