Problems solved by technology
[0005] At present, the SMD white light lamps of most manufacturers use red, green, and blue chips, some of which are arranged in a triangle, and some are arranged in a line. The wavelength of this color is relatively wide, resulting in insufficient light radiation saturation, so the color rendering index is low
[0006] There are also manufacturers who add red, green, blue, and yellow chips into the bracket cup, but this kind of color mixing causes insufficient light radiation saturation, and the color rendering index cannot be effectively improved.

Embodiment Construction
[0027] Below in conjunction with accompanying drawing, structure and working process of the present invention will be further described.
[0028] Such as figure 1 As shown, the combined patch LED white light lamp includes a support cup, a white chip, a red chip, a green chip, and a blue chip. In the middle part, the red chip, the green chip, and the blue chip are evenly arranged around the white chip, and there is an interval between the white chip, the red chip, the green chip, and the blue chip and they are on the same horizontal plane; the transparent colloid is filled around the chip , the transparent colloid fills the inside of the bracket cup.
[0029] By setting the white chip in the middle of the bottom of the holder cup, the red chip, green chip and blue chip are arranged in a triangle around the white chip, so that the LED white light after production is white when viewed from any angle, and there will be no difference. Position observation will produce different c...

The invention discloses a combined type surface mount device LED white-light lamp and a color rendering adjusting packaging method. The rim of a support cup of the LED white-light lamp is upwards arranged on a support fixing frame. A white wafer, a red wafer, a green wafer and a blue wafer are arranged at the bottom inside the support cup, and intervals are formed among the white wafer, the red wafer, the green wafer and the blue wafer in a pairwise mode. The surface mount device LED white-light lamp is obtained through glue dispensing, wafer fixing, primary baking, wire bonding, glue potting and secondary baking. Through additionally arranging the white wafer, the wavelength range of a mixed color is from 400 nm-820 nm, the wavelength range is wide, monochromatic spectrums are wide, wavelengths of all colors are large, the color rendering index is increased by 85%, good color rendering performance is achieved, and the presented colors are bright and lifelike.
Description
technical field [0001] The invention belongs to the technical field of LED applications, and in particular relates to an RGB combined patch LED white light lamp and a color rendering adjustment packaging method thereof. Background technique [0002] RGB combined patch (SMD) LED white light is more and more widely used. SMD three-crystal RGB mixed white light is to put red, green and blue chips in the same bracket cup and drive them with different currents to form White light, the colors emitted by three-color chips can form various white light colors with different effects. When the ratio of the brightness of red, green and blue is 3:6:1, the color formed is pure white. [0003] Because SMD white light can well solve problems such as brightness, viewing angle, flatness, reliability, and consistency, it can effectively reduce the weight of products by reducing size and weight, and finally make the application more common. Therefore, SMD white light has become popular in recen...
