Abstract
The utility model relates to an LED, in particular to a dual-spectrum LED chip. The LED chip comprises a blue light LED and a red light LED which are arranged on a substrate in parallel, a positive pole A and a negative pole B are arranged on each of the two LEDs, and aluminate fluorescence power is coated on the surfaces of the blue light LED and the red light LED. In order to improve the spectrum quality (Ra) of white light, the red light LED is additionally arranged on the basis of the original single blue light LED, then the green aluminate fluorescence power is mixed with the red light to promote to produce high-quality white light, the spectrum quality Ra of the white light is more than 90, as a result, human eyes are prevented against aging injury; in addition, the material of the aluminate fluorescence power is easy to get, so that the cost is low; and the LED chip provided by the utility model is produced without changing the overall manufacturing technique much or employing new equipment, therefore, the LED chip is easy to popularize and apply.
Description
Technical field
The utility model relates to a kind of LED, is specially a kind of pair of spectrum led chip.
Background technology
At present, the LED white light source great majority that the LED illuminating industry uses are to adopt single blue-light LED chip and the allotment of YAG fluorescent material to mix the generation white light, and this is a kind of generating white light principle of simple type, and is with low content of technology, is easy to by a large amount of production.But (Ra) is low for the spectral qualities of this white light, namely light source turns back in people's the eyeball in the reflection of shining material, material color rendition percentage (the COLOR REDEFINE INDEX that obtains, be called for short CRI), it is a kind of white light of inclined to one side blue wave band, it or not best white light, mainly be because this is that single spectrum is luminous, only do compensation with fluorescent material, lack ruddiness and green glow, this white light excites only can obtain partially blue cold light spectrum, the quality Ra of white-light spectrum color＜70, can produce to human eyeball the shortcomings such as aging injury, especially developmental children be had bad impact.
The utility model content
For problems of the prior art, the purpose of this utility model is to provide the technical scheme of a kind of pair of spectrum led chip.
Described pair of spectrum led chip comprises a blue-ray LED and a red-light LED, and blue-ray LED and red-light LED are set up in parallel on substrate, has two electrodes of anodal A and negative pole K, at blue-ray LED and red-light LED surface-coated aluminate fluorescent powder is set.
Described pair of spectrum led chip, described aluminate fluorescent powder are green aluminate fluorescent powder.
For the quality (Ra) of improving the white-light spectrum color, the utility model adds red-light LED on the basis of original single blue-ray LED, and then allocate with green aluminate fluorescent powder, can excite the white light that produces high-quality, the quality of white-light spectrum can reach Ra＞90, can not produce aging injury to human eye; And aluminate fluorescent powder draws materials easily, and cost is low; Produce led chip of the present utility model, its integral production process variations is little, does not also need to adopt new equipment, is easy to apply.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with Figure of description the utility model is described further:
Two spectrum led chips, basis at existing single blue-ray LED 1 adds red-light LED 2, blue-ray LED 1 and red-light LED 2 are set up in parallel on substrate, have two electrodes of anodal A and negative pole K, at blue-ray LED 1 and red-light LED 2 surface-coated green aluminate fluorescent powder is set, then to applying voltage between anodal A and the negative pole K, can excites the white light that produces high-quality, the quality of white-light spectrum can reach Ra＞90, can not produce aging injury to human eye.
The utility model aluminate fluorescent powder is drawn materials easily, and cost is low, and produces led chip of the present utility model, and its integral production process variations is little, does not also need to adopt new equipment, is easy to apply.
Claims (2)
1. two spectrum led chips is characterized in that comprising a blue-ray LED and a red-light LED, and blue-ray LED and red-light LED are set up in parallel on substrate, have two electrodes of anodal A and negative pole K, at blue-ray LED and red-light LED surface-coated aluminate fluorescent powder are set.
2. according to claim 1 pair of spectrum led chip is characterized in that described aluminate fluorescent powder is green aluminate fluorescent powder.
