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

[0027] like figure 1 As shown in the figure, the super-brightness LED fixed inner seat based on the principle of three primary colors includes at least an inner seat 2, an outer shell 4 and a drive circuit. There are three kinds of LEDs of RGB distributed proportionally on the inner seat 2, and the outer shell 4 is covered. On seat 2, the three RGB LEDs are covered by the reflective surface A in the housing to the condensing surface on the housing according to the assigned divergence angle under the action of the driving circuit, and the three RGB LEDs are mixed into white light after being covered by the condensing surface 5. After being softened by the condensing surface 5, white light with a required color temperature is emitted outward.

[0028] The three RGB LEDs are driven by the drive circuit in the lamp holder 1 to emit three colors of red, green and blue (RGB). The center of the semi-circular inner seat 2 emits light outward, and when the angles of the same size in d...

Embodiment 2

[0038] 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

[0042] 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 method for designing a fixing inner base of an LED with ultrahigh brightness based on the principle of three primary colors. The fixing inner base of the LED with the ultrahigh brightness is characterized by at least comprising an inner seat, a casing and a driving circuit. Red, green and blue (RGB) LEDs which are distributed in proportion are distributed on the inner seat, and the casing is covered on the inner seat. Under action of the driving circuit, the RGB LEDs cover a light collecting surface on the casing respectively according to distributed divergence angles through a light reflection surface A in the casing, the red light, the green light and the blue light are mixed into the white light after the RGB LEDs cover the light collecting surface, and then the light collecting surface softly and backwards emits the white light requiring the color temperature. The method for designing the fixing inner base of the LED with the ultrahigh brightness based on the principle of the three primary colors is good in radiating performance and light mixing technology and simple in circuit.

Description

technical field [0001] The invention relates to an LED white light lamp, in particular to a design method for an ultra-high brightness LED fixed inner seat 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 light chip + yellow phosphor to obtain white light. This kind of white light has the lowest cost, but the wavelength shift, intensity change and 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 harmonious 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 t...
