Problems solved by technology

[0003] The main shortcoming of the yellow light LED of prior art is: luminous brightness is low, and luminous flux is little (being that lumen is little), and generally speaking is 40-50lm luminous flux bright, thereby causes yellow light LED illumination brightness to be unsatisfactory, even if it is achieved High brightness but the corresponding LED light attenuation increases

Embodiment

[0022] In order to evaluate the performance and applicability of the phosphor powder, a 1 watt high-power and lamp sample was tested and analyzed with the phosphor powder mixed with silica gel, and its photoelectric performance was tested and analyzed, and its light-up reliability at room temperature was evaluated. Trial production of high-power yellow LED

[0023] Xuming SL-V-B45AC red light chip and Kerui CR-V-A45AC red light chip are used in the trial production process, and Z0603-03BU / O-T bracket is used to try to make 1W high-power white light. The manufacturing process of the phosphor layer is as shown in FIG. 2 .

[0024] Note: The LED outer sealant is OE-6630 silica gel, and the baking conditions are: 80℃×0.5hr+150℃×1.0hr

[0025] According to the different wave bands of the chips, Hongda 0432 and 00902 phosphors were selected as the comparison phosphors to make comparison samples. The following are the test results of the trial production (the first group uses Xuming...

Abstract

The invention relates to a high-power and high-luminance yellow light LED, which is characterized in that: the LED comprises a plurality of high-luminance wafers; and the plurality of high-luminance wafers are coated with a fluorescent powder layer formed by fluorescent powder. The high-power and high-luminance yellow light LED has higher light luminance, better luminous effect, slow optical attenuation, long service life and no light spot, and overcomes the defect of white light dazzling.

Description

technical field [0001] The invention relates to a light-emitting diode (LED), in particular to a high-power and high-brightness yellow light-emitting diode lamp. Background technique [0002] Light-emitting diode (LED for short) is a kind of semiconductor diode, which can convert electrical energy into light energy. Compared with small incandescent bulbs and neon lamps, LED has the following characteristics: the working voltage is very low (some are only a few volts); Good, high reliability, long life; by modulating the strength of the passing current, the intensity of the luminescence can be easily modulated. According to the different semiconductor materials used in the manufacture of light-emitting diodes, the light-emitting wavelengths of ordinary monochromatic light-emitting diodes are different, and thus the light-emitting colors are also different. Among them, the wavelength of yellow light-emitting diodes is generally about 585nm. [0003] The main shortcoming of t...
