Description

A kind of LED lamp of ability free adjustment colour temperature
Technical field
The utility model relates to the photoelectric lighting technical field, relates in particular to a kind of LED lamp of ability free adjustment colour temperature.
Background technology
LED (Light Emitting Diode), light emitting diode, its basic structure is an electroluminescent semi-conducting material, places on the leaded shelf, uses epoxy sealing all around then, plays the effect of protection internal core.LED is a kind of solid-state semiconductor devices, and it can directly be converted into light to electricity.Since the LED lamp comes out, rely on advantages such as its energy-saving and environmental protection, life-span are long, receive the attention and the application of numerous industries, be called the 4th generation light source.
Colour temperature refers to light wave under different energy, the change color that human eyes is experienced.In the LED product, an important specification numeral is exactly a colour temperature, and this is related to the color characteristics that LED lighting product is shown, general light fixture also all has the specification of colour temperature.Colour temperature height measurement unit is with KelvinScale, just is unit with K.The colour temperature of standard daylight is greatly about 5200~5500K, and the reference color temperature that is applied to lighting field is 2200K (warm white)~10000K (a cold white light).
And the colour temperature of LED lamp control is to be employed in the lamp bead seal process of assembling proportioning of fluorescent material controlled to realize mostly; And the lamp pearl that this control mode obtains can only have a color temperature value; The colour temperature scheme is very single; Therefore how in the LED lamp, to realize the free adjustment of multiple colour temperature, become the technical problem of being badly in need of solution.
Chinese patent discloses patent name and has been " the LED illuminating lamp that colour temperature is adjustable "; Application number is the utility model patent of " CN201010546470.X "; Its clip Text, the LED illuminating lamp that colour temperature is adjustable belongs to the electrical application technology field; Include shell body, equal tabula rasa and printed circuit board (PCB); It is characterized in that on printed circuit board (PCB), to shell body one side three-terminal voltage regulator (IC1, IC2), current limliting sample resistance (R1, R2) are housed, low colour temperature, warm-toned light emitting diode and white light emitting diode are equipped with in the another side; Intersect to be evenly arranged on the printed circuit board (PCB) and by independent constant-current source and supply power respectively, described each constant-current source is made up of three-terminal voltage regulator and current limliting sample resistance; Between constant-current source that hangs down colour temperature, warm-toned led powered and dc voltage electrode end, be provided with gauge tap (K).The utility model sends the drawback of inclined to one side blue and white light through the luminous illuminating lamp that remedies and correct original white light LEDs composition of low colour temperature light emitting diode; The lighting environment different according to the user; Build warm, steady lighting atmosphere, satisfy the demand of different application environment.
It is to adopt low colour temperature and two groups of evenly distributed obtaining of LED lamps intersection of warm tones that above-mentioned patent is taked scheme; Though obtain the adjustable effect of LED light color temperature, but adopted more LED lamp, its cost is higher; And the color temperature value of being transferred is comparatively single, can not realize the free adjustment of LED lamp color temperature value.
The utility model content
The technical problem that the utility model will solve is in order to overcome technological deficiency recited above, a kind of LED lamp of ability free adjustment colour temperature to be provided.
In order to solve technical problem recited above, the utility model is taked following technical scheme:
A kind of LED lamp of ability free adjustment colour temperature; Include the LED reflector of lamp, described LED reflector of lamp further include housing and with the integrated base plate of housing, be installed in the LED lamp plate on the base plate; Be installed in the LED lamp on the LED lamp plate; The LED lamp is electrically connected with led driver through lead, also is provided with flourescent sheet in the described LED reflector of lamp, and described flourescent sheet is positioned at the top of LED lamp; Described LED lamp further includes blue LED lamp and red-light LED lamp, and described led driver is connected with the red-light LED brightness regulator through lead.
Described inner walls is provided with upper flange and lower flange, and described flourescent sheet is placed between upper flange and the lower flange.
Described LED lamp plate is fixedly mounted on the base plate through fixed screw.
A kind of LED light color temperature free adjustment method as described above may further comprise the steps: light blue LED lamp, this moment the red-light LED lamp zero luminance, the effect of blue LED lamp and flourescent sheet produces cold white light; Regulate the brightness of red-light LED lamp then through the red-light LED brightness regulator, realize the colour temperature free adjustment of LED lamp.
The adjustable range of the color temperature value of LED lamp is 2200K~10000K, wherein,
When the brightness of red-light LED lamp was 0, color temperature value was 10000K;
When the brightness of red-light LED lamp was 100%, color temperature value was 2200K.
The LED lamp of the utility model adds red-light LED lamp and blue LED lamp in same light fixture; And the mode that adopts blue LED lamp to combine with flourescent sheet produces white light; Simultaneously through regulating the brightness of red-light LED lamp; Make the color temperature value of the white light that the LED lamp sends can be between 2200K (warm white)~10000K (cold white light) free adjustment, remedied the defective that the color temperature value of existing LED lamp can not regulated at will greatly.The diversity that the LED lamp of the utility model provides color temperature value to change is applicable to the illumination of all kinds of industries.
