ABSTRACT:
A method for generating low color temperature light and a light emitting device adopting the same, comprise a LED component, phosphor capable to be excited by the emission light of the LED component, and a package colloid for encapsulating the LED component and the phosphor, wherein the package colloid is provided with a electrode lead for connecting the LED component with the external power supply, the peak wavelength of emission light of the LED light is 460-500 nm, the peak wavelength of emission light of the excited phosphor is 580-630 nm. The present invention only use one chip and one kind of phosphor to generate the low color temperature light which is of the same effect as that of the minitype tungsten lamp or the high pressure sodium lamp, and is of advantages including energy saving, low cost and environmental protection, etc. The present invention can be widely used in the manufacturing process of LED lamp of low color temperature, especially in the manufacturing the mini LED bulb.
