Problems solved by technology

However, the precision of this method of light splitting is low, and it is impossible to actively control and adjust the light color of white LEDs, resulting in unstable quality of the same batch of LED products
Even if white LEDs are categorized into the same category, there are still differences in light color and light intensity.

Abstract

The invention provides an LED light source module capable of splitting light in advance. The LED light source module comprises a bracket; a heat dissipation cup is arranged at the upper part of the bracket; a copper block and an electrode are arranged at the bottom of the heat dissipation cup; the copper block is provided with a blue light chip; a wire is connected between the blue light chip and the electrode; the blue light chip is wrapped with a fluorescent glue; and the LED light source module is characterized in that a transparent separating layer is further arranged between the blue light chip and the fluorescent glue. According to the LED light source module capable of splitting light in advance, the blue light chip is protected by the transparent separating layer before dispensing the fluorescent glue to prevent the blue light chip from being damaged in a light splitting device so as to realize the purpose of splitting light before dispensing glue. The invention also provides a preparation method for the LED light source module capable of splitting light in advance; light-splitting is performed on the blue light LED in advance before dispensing the fluorescent glue, and the fluorescent glue is prepared according to the light-splitting result, so that the light color and the light intensity of the prepared LED light source module can be controlled, and the LED products without color difference, with stable quality and good lighting effect are obtained.

Description

technical field [0001] The invention relates to an LED light source module and a preparation method thereof, in particular to an LED light source module with front-stage light splitting and a preparation method thereof. Background technique [0002] LED (Light Emitting Diode) is a semiconductor that can convert electrical energy into light energy. It changes the principle of tungsten filament luminescence of incandescent lamps and three-based toner luminescence of energy-saving lamps, and uses electric field luminescence. The spectrum of white light LEDs is almost all concentrated in the visible light frequency band. Comparing white light LEDs with ordinary incandescent lamps, spiral energy-saving lamps and tricolor fluorescent lamps, the characteristics of LEDs are very obvious: long life, high luminous efficiency, low radiation and low power consumption. It is precisely because of these advantages of LED that white LED lighting has entered a period of rapid development. W...
