Abstract
The utility model relates to a light-emitting diode (LED) white lamp with a red-light chip, which mainly solves the problems that the white light of the traditional LED white lamp is formed by mixing the glue light and the yellow light, the light spectrum is single, the color rendering is poor, and the light quality is bad. The LED white lamp with the red-light chip comprises a circuit board, a light shading part is arranged on the circuit board, and a round hole is arranged in the center of the light shading part. A blue-light chip connected with the circuit board is arranged at the bottom of the round hole, and the red-light chip is further installed at the bottom of the round hole. The LED white lamp with the red-light chip has the advantages that the red-light chip is added on the basis that the traditional LED white lamp only has the blue-light chip, thereby improving the color rendering of the LED white light, enabling the spectral components of the white light to be abundant, being closer to the natural light and almost continuous spectrum, and leading the LED white light to be suitable for fields which has a high requirement for color rendering of a light source, such as coffee houses, evening party illumination, hotel illumination and the like.
Description
Technical field
The utility model relates to a kind of LED lighting, relates in particular to the good white lamp of the LED with red light chips of a kind of colour rendering.
Background technology
Because the white lamp of traditional LED is to produce gold-tinted or green-yellow light by the luminous excitated fluorescent powder of blue chip, make blue light mix the generation white light according to a certain percentage with gold-tinted or green-yellow light, this white light only contains blue light and gold-tinted or green-yellow light, 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 to the quality requirements of light, party field lighting and hotel illumination, lighting for medical use, clap the scene that shooting illumination mutually waits these that colour rendering of light source is had relatively high expectations.As Granted publication number is CN201100557Y, name is called a kind of with yellow, the Chinese utility model of the LED street lamp of the synthetic warm white of blue two kinds of color LED, 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 utility model has mainly solved traditional its white light of LED white light and has been formed by blue light and yellow light mix, and spectrum is single, colour developing is poor, the problem of light inferior quality, and the white lamp of the LED with red light chips that a kind of spectral component is abundant, colour developing is high is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of white lamp of LED with red light chips, comprise the pin support, the pin support 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 red light chips on the bottom of circular hole.The utility model has only at the white lamp of tradition on the basis of blue chip and has added red light chips, improved the colour rendering of LED white light, increased red spectrum at the white light composition that originally only contains indigo plant, yellow 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 red light chips 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 red light chips voltage separate, the electric current that can adjust blue chip and the red light chips 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 red light chips is provided with a plurality of, and red light chips 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 the yellow fluorescence bisque.Blue light and ruddiness excite yellow fluorescent powder to produce gold-tinted, make blue light, ruddiness and gold-tinted mix the generation white light by a certain percentage.
The utility model has the advantages that: having only at the white lamp of tradition on the basis of blue chip to have added red light chips, 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.
