Description
Technical field
The present invention relates to a kind of illuminating lamp, particularly relate to the adjustable LED illuminating lamp of a kind of colour temperature, belong to the electrical application technology field.
Background technology
Characteristics such as the efficient height of LED lighting, the life-span is long, energy consumption is low are described as the new type light source of 21 century.The lighting source that adopts dissimilar light emitting diodes to produce has different-colour.Depart from nature white light colour temperature lighting source far away more, its colour rendering index is also low more.
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.
Summary of the invention
The object of the present invention is to provide the adjustable LED illuminating lamp of a kind of colour temperature, 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.
Technical scheme of the present invention 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 invention 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 present invention 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.
Description of drawings
The present invention is described further below in conjunction with drawings and Examples:
Fig. 1 is a lighting cross-sectional view of the present invention;
Fig. 2 is an illumination lamp plate LED Pareto diagram of the present invention;
Fig. 3 is an electrical schematic diagram of the present invention.
Among the figure: IC1, IC2 are three-terminal voltage regulator, and R1, R2 are the current limliting sample resistances, the 1st, and gold-tinted or orange light or red light-emitting diode, the 2nd, white light emitting diode, K are gauge taps, V
DDConnect dc voltage electrode, GND connects the DC voltage negative pole, and the 3rd, printed circuit board (PCB), the 4th, equal tabula rasa, the 5th, shell body.
The specific embodiment
As shown in Figure 1, the LED illuminating lamp that a kind of colour temperature is adjustable, include shell body 5, equal tabula rasa 4 and printed circuit board (PCB) 3, printed circuit board (PCB) 3 is fixed in the shell body 5 inner, all tabula rasa 4 is arranged on the inclined to one side outside, shell body 5 middle parts, and described equal tabula rasa 4 is made by semi-transparent glass, acrylic or plastic material.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) 3, low colour temperature, warm-toned light emitting diode 1 and white light emitting diode 2 are equipped with in the another side.Described low colour temperature, warm-toned light emitting diode 1 are Yellow light emitting diode, orange light-emitting diode, red light-emitting diode or its combination.
As shown in Figure 2, the LED of the LED illuminating lamp that colour temperature is adjustable intersects and to be evenly arranged on the printed circuit board (PCB) 3, but that the layout of low colour temperature, warm-toned light emitting diode 1 and white light emitting diode 2 is not limited to is shown in Figure 2, and it is fixed to come according to client's needs.But it is evenly distributed to adopt 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 the phenomenon that working face can produce inhomogeneous color spot.
As shown in Figure 3, because the forward voltage difference of white light, gold-tinted, orange light, ruddiness different-colour LED, recommended current is also different, for example: the forward voltage of white light LEDs is 3.0V-3.6V, the forward voltage of yellow light LED is 1.6-2.0V, the forward voltage of orange light LED is 1.8-2.1V, and the forward voltage of red-light LED is 2.0--2.4V.Thereby different types of LED simply serial or parallel connection powers together, and should be powered respectively by independent constant-current source.Each constant-current source connects dc voltage electrode end V respectively
