Abstract
The utility model relates to an LED white lamp with red and yellow light chips, which mainly solves the problem that white light of a traditional LED white lamp is a mixture of blue light and green light, so that optical spectrum is single, color rendering is poor and light quality is poorer. The LED white lamp comprises a circuit board, a light shading portion is disposed on the circuit board, a round hole is arranged in the middle of the light shading portion, a blue light chip connected with the circuit board is disposed at the bottom of the round hole, a fluorescent powder layer is arranged on the blue light chip, and a yellow light chip and a red light chip are further arranged at the bottom of the round hole. The LED white lamp has the advantages that the yellow light chip and the red light chip are added to a traditional white lamp only with a blue light chip, color rendering of LED white light is improved, and components of white light spectrum are richer and closer to natural light, while the white light spectrum is nearly a continuous spectrum. Therefore, the LED white lamp is applicable to lighting at places with the higher requirement on light source rendering, such as coffee houses, evening parties, restaurants 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 reddish yellow optical 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 number is CN201100557Y, name is called the Chinese utility model of " a kind of with yellow; the LED street lamp of the synthetic warm plain boiled water light 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 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 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 reddish yellow optical chip 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 reddish yellow optical 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 gold-tinted chip and 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 gold-tinted chip and red light chips, improved the colour rendering of LED white light, in the white light composition that originally only contains indigo plant, green light spectrum, red spectrum and yellow spectrum have been increased, 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, and the anode tap of described red light chips is connected on the 3rd power supply, and cathode terminal is connected to the 3rd earth terminal, described first power supply, second source and the 3rd power supply are respectively independently power supply, and the first ground end, the second ground end and the 3rd ground end are respectively independently to be held.The circuit of supplying with blue chip, red light chips and gold-tinted chip voltage separate, the electric current that can adjust blue chip, gold-tinted 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 gold-tinted chip, red light chips are provided with a plurality of, gold-tinted chip series connection be provided with divide settings that be in parallel again after the some groups of series connection, red light chips series connection to be provided with or divide some groups to connect after the setting that is in parallel 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.Phosphor powder layer infiltrates silica gel by green emitting phosphor to be made, and after energising, blue light, gold-tinted and ruddiness excite green emitting phosphor to produce green glow, make blue light, ruddiness, gold-tinted and green glow 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 gold-tinted chip and 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.
