Abstract

The invention discloses a novel semiconductor lighting source which is characterized in that the light source comprises an LED substrate, LED light-emitting devices, chip resistors and the like. Welding feet, chip resistor welding feet, positive and negative power supply welding feet, metal wires and the like corresponding to the LED light-emitting devices are arranged on the LED substrate; and the LED light-emitting devices are full-color surface-mounted devices. The light source is simple in structure and high in lighting effect, the single-power-supply driving mode of the existing lightingsource is not changed, the currents of the chips R, G and B on the LED device are controlled by arranging the chip resistors with different sizes, so that the light source of any color temperature isobtained so as to meet the lighting requirement of any scene.

Description

technical field

[0001] The invention relates to a novel semiconductor lighting source, which belongs to the application field of semiconductor lighting. Background technique

[0002] As a new type of semiconductor lighting source, LED has the characteristics of excellent energy saving, environmental protection, low cost, and long life. Therefore, it has been widely researched and applied in the fields of lighting and display in recent years. At the same time, with the improvement of people's requirements for light quality and the diversity of light source selection requirements in different application scenarios, more color or performance light sources will be needed in the future to meet the growing lighting applications.

[0003] The existing mainstream LED lighting sources are mainly prepared by exciting yellow phosphor powder with LED blue light (B) chips, such as figure 1 with 2 As shown, the red light (R) and green light (G) generated by excitation are mixed with the...
