Abstract
The utility model discloses a simulated sunlight spectrum integrated optical source which comprises transparent silica gel, an aluminum substrate, blue-light chips and spectrum compensation chips. The transparent silica gel is fixed on the surface of the aluminum substrate and doped with fluorescent powder uniformly, the blue-light chips and the spectrum compensation chips are mounted on the aluminum substrate and embedded in the transparent silica gel, and are in array distribution, and the spectrum compensation chips are arranged in the array of the blue-light chip sequentially alternatively. The integrated optical source is good in color rendering index and high in luminous efficiency owing to the blue-light chips and the spectrum compensation chips. The blue-light chips and the spectrum compensation chips are packaged on the surface of the aluminum substrate reasonably, and are compounded into white light by initiating the fluorescent powder during use. The simulated sunlight spectrum integrated optical source is wide in spectrum scope, high in color rendering index and luminous efficiency, and meets requirements of safety, energy-saving and efficient LED lamps for the market.
Description
Technical field
The utility model relates to a kind of integrated optical source, particularly a kind of emulation spectrum of sunlight integrated optical source.
Background technology
The LED lamp relies on the advantages such as the high and low power consumption of luminous efficiency, security height, is widely used in various lighting fields.But led light source belongs to the narrow spot light of spectrum, and its wavelength has very large gap with spectrum of sunlight between 450 to 600mm.People work long hours and live under LED spectrum, can produce uncomfortable phenomenon, just as under at desk lamp the long-time reading even can cause injury to eyes.Simultaneously, led light source can because its narrow spectrum makes shades of colour produce distortion under its irradiation, be not suitable for using under the working environments such as clothes, the fine arts.In the prior art, LED realizes that the mode of white light is mainly by the chip excitated fluorescent powder compound white light that obtains again, has the shortcomings such as colour rendering is poor, luminous efficiency is low, is difficult to satisfying the market to the demand of safety, energy-conservation, efficient LED lamp.
Summary of the invention
For the deficiencies in the prior art, the utility model provides the emulation spectrum of sunlight that a kind of spectral region is wide, colour rendering good, luminous efficiency is high integrated optical source.
The technical solution of the utility model is: a kind of emulation spectrum of sunlight integrated optical source, comprise transparent silica gel, aluminium base, blue chip, spectrally compensating chip, it is characterized in that: described transparent silica gel is fixed on the aluminium base surface, evenly be mixed with fluorescent material in the transparent silica gel, blue chip and spectrally compensating chip are installed on the aluminium base, and in the embedding transparent silica gel, blue chip and spectrally compensating chip are array distribution, and the spectrally compensating chip array interts in order in the middle of the array of blue chip.
The beneficial effects of the utility model are:
1, the quantity of blue chip and spectrally compensating chip is calculated and is formed according to power, the brightness requirement of whole integrated optical source, simultaneously the drive current of two kinds of chips decides according to the drive current of corresponding white chip, makes that the integrated optical source colour rendering is good, luminous efficiency is high;
2, utilize the multi-chip package technology that blue chip and spectrally compensating chip rationally are encapsulated in the aluminium base surface, two kinds of chips are by exciting the fluorescent material compound white light that obtains again in the transparent silica gel during use, and the light that integrated optical source is sent reaches the spectrum of emulation daylight.
Therefore, the utility model spectral region is wide, colour rendering good, luminous efficiency is high, has satisfied the demand of market to safety, energy-conservation, efficient LED lamp.
Description of drawings
Fig. 1 is the structural representation of a kind of emulation spectrum of sunlight integrated optical source described in the utility model.
Among the figure, 1-transparent silica gel, 2-aluminium base, 3-blue chip, 4-spectrally compensating chip.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:
As shown in Figure 1, a kind of emulation spectrum of sunlight integrated optical source, comprise transparent silica gel 1, aluminium base 2, blue chip 3, spectrally compensating chip 4, transparent silica gel 1 is fixed on aluminium base 2 surfaces, the transparent silica gel 1 interior fluorescent material that evenly is mixed with, blue chip 3 and spectrally compensating chip 4 are installed on the aluminium base 2, and embed in the transparent silica gel 1, blue chip 3 and spectrally compensating chip 4 are array distribution, and spectrally compensating chip 4 arrays intert in order in the middle of the array of blue chip 3.
The quantity of blue chip of the present utility model and spectrally compensating chip is calculated and is formed according to power, the brightness requirement of whole integrated optical source, simultaneously the drive current of two kinds of chips decides according to the drive current of corresponding white chip, makes that the integrated optical source colour rendering is good, luminous efficiency is high; Utilize the multi-chip package technology that blue chip and spectrally compensating chip rationally are encapsulated in the aluminium base surface, two kinds of chips are by exciting the fluorescent material compound white light that obtains again in the transparent silica gel during use, and the light that integrated optical source is sent reaches the spectrum of emulation daylight.The utility model spectral region is wide, colour rendering good, luminous efficiency is high, has satisfied the demand of market to safety, energy-conservation, efficient LED lamp.
