Problems solved by technology

[0004] However, the color temperature of the existing LED lighting source is fixed, and it is mainly concentrated in the range of white light color temperature range or single-color lighting. For other light sources with any color temperature, it is very scarce due to the limitation of the light emitting method. To achieve the lighting scene with the required effect, the existing light sources can no longer meet the requirements
At the same time, the existing lighting sources rely on the conversion of excited phosphors to achieve lighting, which has low light efficiency and large light loss

Embodiment

[0033] Such as image 3 As shown, the light source includes an LED substrate 1, several LED devices 2 and three chip resistors 31-33, wherein the surface of the LED substrate 1 is provided with positive and negative power supply soldering pins 4, and corresponding corresponding pins on the LED devices 2. Welding feet 5, welding feet 61-63 for placing chip resistors 31-33, metal traces 9, etc., such as Figure 4 with Figure 5 As shown, the metal traces 9 are used to connect the above welding feet and form a circuit. In addition, ink or paint is applied to the surface of the LED substrate 1 except for all the welding feet for wrapping protection; the LED device 2 is a full-color display. Paste the device without fluorescent powder. The LED device selected in this embodiment has a structure of six pins and eight, including 1R1G1B LED chips 71-73, and the position of each LED chip can be adjusted and placed arbitrarily. The LED device 2 is fixed on the corresponding welding fee...

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...
