Abstract

The invention discloses an LED white light illuminating bulb which comprises a bearing substrate, a plurality of red light LED packaging elements, a plurality of green light LED packaging elements, a plurality of blue light LED packaging elements, a shield-type light housing and a conductive element, wherein the red light LED packaging elements, the green light LED packaging elements and the blue light LED packaging elements are arranged on the bearing substrate, and each red light LED packaging element, each green light LED packaging element and each blue light LED packaging element are respectively provided with a red light emitting LED wafer, a green light emitting LED wafer and a blue light emitting LED wafer, a covering body which respectively covers the red light LED wafer, the green light LED wafer and the blue light LED wafer and a plurality of diffusion particles distributed in the covering body; the shield-type light housing is connected to the periphery of the bearing substrate so as to close the non-emitting directions of the red light LED packaging elements, the green light LED packaging elements and the blue light LED packaging elements; and the conductive element is connected to the shield-type light housing, electrically connected with the bearing substrate and used for switching an external power supply onto the red, the green and the blue light LED wafers. The LED white light illuminating bulb has the advantages of even light mixing, easy color temperature adjustment and high rendering.

Description

Technical field [0001] The invention relates to a lighting bulb, in particular to an LED white light lighting bulb with uniform light mixing, easy adjustment of color temperature and high color rendering. Background technique [0002] As Light Emitting Diode (LED for short) has the characteristics and advantages of low energy consumption and high efficiency, countries and industries currently list this technology as a key technology for strategic development to replace the existing traditional lighting equipment. [0003] Such as figure 1 As shown, in the existing LED lighting bulb, a plurality of LED elements 1, 2, and 3 that can emit red, green, and blue light are electrically connected to a circuit board 4, and then the circuit board 4 is connected to a circuit board 4. The connecting terminal (not shown in the figure) is electrically connected to the power supply or the lamp holder through the connecting terminal to achieve the purpose of using the three primary colors (red, gr...
