Abstract
The invention relates to a light emitting diode (LED) lamp with low cost, high light flux and high color rendering index. The LED lamp at least comprises a white LED string, wherein a color LED is connected with the white LED string in series. In the method, the high color rendering property of the LED lamp in which a plurality of LED strings are connected in parallel is easily realized; and for the LED lamp of the same type, compared with an exported LED which has high light flux and high color rendering index, an LED which is manufactured by combining a domestic white LED with high color rendering index and a red LED to adjust the color rendering index has the advantage that: the cost can be reduced by 60 percent.
Description
Technical field
The present invention relates to a kind of low-cost high light flux high color rendering index (CRI) LED lamp, belong to LED lamp technical field.
Background technology
High light flux high-color rendering light source has its potential application prospect in special lighting places such as museum, operations.Design the light fixture of the logical high-color rendering of high light and can realize that cost is quite high by buying external esbablished corporation LED particle; Buy the LED particle of Taiwan and CONTINENTAL AREA OF CHINA, price is lower, is to be cost with the sacrificial light flux but this particle will obtain high-color rendering, can not high-color rendering and high light flux have concurrently.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned existence, the LED lamp of a kind of high light flux and high colour developing is provided.
The objective of the invention is to finish by following technical solution, a kind of low-cost high light flux high color rendering index (CRI) LED lamp which comprises at least the white light LEDs string, and colourama LED is connected in series in the described white light LEDs string.
Described colourama LED is the combination of red light LED or red light LED and blue-light led.
This method realization high-color rendering in by a plurality of LED strings LED lamp also becomes and is more prone to; Same a LED lamp adopts above-mentioned method to add red light LED adjustment colour rendering index with homemade high light flux white light LEDs and can reduce by 60% than directly buying external high light flux high color rendering index (CRI) LED cost.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done detailed introduction: as shown in Figure 1: a kind of low-cost high light flux high color rendering index (CRI) LED lamp, which comprises at least white light LEDs string 1, colourama LED is connected in series in the described white light LEDs string 1.
Described colourama LED is the combination of red light LED2 or red light LED2 and blue-light led 3.
Embodiment 1:
On five high-power one watt white light LEDs string 1, add three red light LED2 and two green light LED3, the purpose that adds red light LED2 is the colour rendering index that increases whole lamp, adding green light LED3 then is to cause whole lamp color red partially for fear of the adding because of red light LE2, whole like this lamp has improved colour rendering index, does not also have influence on the visual effect of whole lamp.
Claims (2)
1. a low-cost high light flux high color rendering index (CRI) LED lamp which comprises at least white light LEDs string (1), it is characterized in that the colourama LED that is connected in series in the described white light LEDs string (1).
2. low-cost high light flux high color rendering index (CRI) LED lamp according to claim 1 is characterized in that described colourama LED is the combination of red light LED (2) or red light LED (2) and blue-light led (3).
