Problems solved by technology

However, the problem of this method is that the conversion efficiency of green light is low, it is difficult to mix light, and the design of the driving circuit is complicated.
In addition, since these three light colors are heat sources, the heat dissipation problem is three times that of other packaging forms, which increases the difficulty in use

Embodiment 1

[0029] Such as figure 1 As shown, the ultra-high-brightness LED mixed white light method based on the principle of three primary colors, it at least includes the inner seat 2, the outer shell 4 and the driving circuit, and the inner seat 2 is distributed with three kinds of RGB LEDs distributed in proportion, and the outer shell 4 covers it. On the seat 2, under the action of the drive circuit, the three kinds of RGB LEDs are respectively covered by the reflective surface A in the casing to the light-gathering surface on the casing according to the assigned divergence angle, and the RGB three kinds of LEDs are mixed into white light after being covered by the light-gathering surface 5. After being softened by the light-gathering surface 5, the white light with required color temperature is emitted outwards.

[0030] Three kinds of RGB LEDs are driven by the driving circuit in the lamp holder 1 to emit three colors of red, green and blue (RGB). The center of the semicircular i...

Embodiment 2

[0040] The hemispherical shape of the inner seat 2 is for the convenience of LED optical design, such as figure 2 In another structure, under this structure, the inner seat 2 also chooses a hemispherical shape, and there are two circles of LED base strips 10 in different layers of the hemisphere, and the two circles of LED base strips 10 respectively circle the main axis to form angles of the same size in different directions At this time, the size of the light-emitting surface of each LED to the reflective surface A is very close, and the size of the light-emitting surface to the reflective surface B is very close, that is, the LEDs from different layers to the reflective surface A and reflective surface B emit light at different levels. angle, but they all continue to diverge after being reflected by the reflective surface, and finally form the same area of ​​coverage on the light-gathering surface 5, and finally emit white light. Embodiment 2 is more suitable for the desig...

Embodiment 3

[0044] When the LED base band 10 on the inner seat 2 only needs one turn, the inner seat 2 is annular, and the LED base band 10 is fixed on the inner seat 2 of the annular shape, and there is a drive circuit in the inner seat 2, and the LED base band 10 and the inner After the seat 2 is fixed, it is electrically connected to the drive circuit through the interface. The LED baseband 10 has two electrode connectors, one positive and one negative. LEDs of various wavelengths on the entire LED baseband 10 are connected in series. The outer shell 4 is connected with the inner seat 2 and then connected with the lamp holder 1, and the lamp holder 1 is a screw socket or a socket or a pin structure.

Abstract

The invention relates to a light-emitting diode (LED) white light lamp, in particular to a three-primary-color-principle-based ultra-high-brightness LED white light mixing method. The method is characterized in that: an inner seat, a shell, and a drive circuit are at least involved; red, green and blue (RGB) LEDs are distributed on the inner seat in a proportion; a shell is covered on the inner seat; and light emitted by the RGB LEDs covers a condensation surface of the shell through a reflection surface A in the shell at a distributed divergence angle under the action of the drive circuit, and then is mixed to form white light, and the white light is softened by the condensation surface and then the white light with required color temperature is emitted outward. The invention provides the three-primary-color-principle-based ultra-high-brightness LED white light mixing method in which the radiating effect is good, process mixing manufacturability is high and a drive circuit is simple.

Description

technical field [0001] The invention relates to an LED white light lamp, in particular to an ultra-high brightness LED mixed white light method based on the principle of three primary colors. Background technique [0002] There are three kinds of existing LED white light lamps. The first one is a relatively mature and commercialized blue chip + yellow phosphor to obtain white light. The change of phosphor coating thickness will affect the uniformity of white light, and the spectrum is narrow, the color is incomplete, the color temperature is high, the color rendering is low, and the light is not soft and uncoordinated to the eyes. The human eye is most adapted to sunlight after evolution, and the continuous spectrum of incandescent lamps is the best, with a color temperature of 2500K and a color rendering index of 100. Therefore, this kind of white light still needs to be improved, such as adding more light-emitting processes to improve the spectrum and make it continuous a...
