Abstract
The invention relates to a light emitting diode (LED) white lamp with a yellow light chip and mainly solves the problems of single light spectrum, poor colour rendering and poorer light quality because a white light of the conventional LED white lamp is formed by mixing a blue light and a green light. The LED white lamp with the yellow light chip comprises a circuit board, wherein a light-shading part is arranged on the circuit board; a circular hole is formed in the middle of the light-shading part; a blue light chip which is connected with the circuit board is arranged at the bottom of the circular hole; a phosphor powder layer is arranged on the blue light chip; and the yellow light chip is also arranged at the bottom of the circular hole. The LED white lamp with the yellow light chip has the advantages that: the yellow light chip is added into the conventional white lamp which has only the blue light chip; the colour rendering property of the LED white light is improved, so light spectrum components of the white light are relatively rich, the white light is more approximate to a natural light, and the light spectrum is almost a continuous light spectrum; and the LED white lamp can be applied to lighting of fields with high colour-rendering requirement on a light source such as a cafe, an evening party and a hotel.
Description
Technical field
The present invention relates to a kind of LED lighting, relate in particular to the good white lamp of the LED with gold-tinted chip of a kind of colour rendering.
Background technology
Because the white lamp of traditional LED is to produce green glow by the luminous excitated fluorescent powder of blue chip, make blue light mix the generation white light according to a certain percentage with green glow, this white light only contains blue light and green glow, spectrum is single, colour rendering is relatively poor, colour rendering index has only about 70-75, the inferior quality of light, this light source can only be used in the general lighting occasion, cannot be used in the place higher, as coffee shop, party field lighting and hotel illumination, lighting for medical use, bat these scenes that colour rendering of light source is had relatively high expectations such as illumination of making a video recording mutually to the quality requirements of light.As Granted publication position CN201100557Y, name is called a kind of with yellow, the Chinese utility model of the LED street lamp of the synthetic warm white of color LED in blue two, this LED street lamp comprises lamp housing, constant-current source, the LED lamp plate is arranged in lamp housing, on the LED lamp plate, be welded with Huang, blue two kinds of color LED, this LED street lamp passes through Huang, blue two kinds of color of light synthesize white lights are as road-light light-source, this has just had above-mentioned shortcoming: this white-light spectrum is single, colour rendering is relatively poor, the inferior quality of light, light source can only be used in the general lighting occasion, cannot be used in the place higher to the quality requirements of light.
Summary of the invention
The present invention has mainly solved traditional its white light of LED white light and has been mixed by blue light and green glow, and spectrum is single, colour developing is poor, the problem of light inferior quality, and the white lamp of the LED with gold-tinted chip that a kind of spectral component is abundant, colour developing is high is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of white lamp of LED with gold-tinted chip, comprise circuit board, circuit board is provided with shading light part, in the middle of shading light part, be provided with circular hole, the bottom of circular hole is provided with the blue chip that is connected with circuit board, also is provided with the gold-tinted chip on the bottom of reflector.The present invention has only at the white lamp of tradition on the basis of blue chip and has added the gold-tinted chip, improved the colour rendering of LED white light, increased yellow spectrum at the white light composition that originally only contains indigo plant, green light spectrum, make that like this white-light spectrum composition is abundanter, near natural daylight, almost be continuous spectrum more.Make the white lamp of LED can be applicable to that coffee shop, party illumination, hotel illumination etc. are to the light source demanding place of developing the color.
As a kind of preferred version, the anode tap of described gold-tinted chip is connected on first power supply, cathode terminal is connected to the first ground end, the anode tap of described blue chip is connected on the second source, cathode terminal is connected to the second ground end, described first power supply and second source are two independently power supplys, and the first ground end and the second ground end are two and independently hold.The circuit of supplying with blue chip and gold-tinted chip voltage separate, the electric current that can adjust blue chip and the gold-tinted chip so respectively temperature of mixing colours, and the while has also been improved the colour rendering of the white lamp of LED.
As a kind of preferred version, described gold-tinted chip is provided with a plurality of, and the gold-tinted chip is in parallel after dividing some groups of series connection again.
As a kind of preferred version, described blue chip is provided with a plurality of, and blue chip is in parallel after dividing some groups of series connection again.
As a kind of preferred version, in circular hole, be filled with phosphor powder layer, described phosphor powder layer is a green phosphor layer.Blue light and gold-tinted excite green emitting phosphor to produce green glow, make blue light, green glow and gold-tinted mix the generation white light by a certain percentage.
Advantage of the present invention is: having only at the white lamp of tradition on the basis of blue chip to have added the gold-tinted chip, improved the colour rendering of LED white light, make that the white-light spectrum composition is abundanter, more near natural daylight, almost is continuous spectrum.Make the white lamp of LED can be applicable to that coffee shop, party illumination, hotel illumination etc. are to the light source demanding place of developing the color.
