Problems solved by technology

[0003]The disadvantage of the existing LED lights is that the color temperature control scheme for the finished product is relatively simple, and it is only adjusted by the phosphor powder ratio, so that when the color temperature requirement is low, the color rendering The index and luminous efficacy are seriously reduced
Because blue light is used to excite phosphors to produce white light, generally the luminous efficiency of phosphor excitation is the highest when the color temperature is about 5500k, and when the color temperature is lower or higher, the ratio of phosphors needs to be adjusted, which will lead to the excitation of phosphors Decreased light efficiency due to decreased efficiency
Moreover, the existing LED lights need LED lamp bead brackets, and the structure is relatively complicated

Abstract

The invention discloses a method for manufacturing a color temperature tunable LED lamp and the LED lamp. The method comprises the following steps: distributing a circuit board and fixed welding positions of LED chips on a substrate according to the luminance distribution conditions and manufacturing requirements of a plurality of LED chips; selecting a material for contact positions of the substrate and the LED chips according to material types of base layers of the LED chips, and carrying out adhesive dispensing and fixed welding on the substrate; blending different proportions of fluorescent powder according to the color temperature requirement of the LED lamp, and mixing and stirring the fluorescent powder and silica gel according to the required proportion; dispensing the mixed fluorescent powder gel on the surfaces of the LED chips; and baking the LED chips, coating with protective adhesive, and completing the encapsulation process of the plurality of LED chips. The manufacturing method has advanced process and easily controlled flow. The color temperature tunable LED lamp has good color rendering index and high luminous efficiency, and the color rendering index and the luminous efficiency cannot be reduced because of the change of the color temperature.

Description

technical field [0001] The invention relates to the field of lamp lighting, in particular to a method for manufacturing an LED lamp with adjustable color temperature and an LED lamp with adjustable color temperature with a novel structure. Background technique [0002] The existing LED lamp packaging technology uses copper-based brackets to package multiple LED lamp beads, and then installs the packaged lamp beads on the aluminum substrate to form a whole LED lamp. The color temperature is controlled by the lamp beads. The color temperature is adjusted by controlling the phosphor powder ratio during the packaging process. [0003] The disadvantage of existing LED lamps is that the color temperature control scheme for the finished product is relatively single, which is only adjusted by the phosphor ratio, so that when the color temperature requirement is low, the color rendering index and luminous efficacy are seriously reduced. Because blue light is used to excite phosphors...
