Abstract
The invention discloses a white-light LED (Light-Emitting Diode) light-emitting module. The white-light LED light-emitting module comprises a substrate, wherein the substrate is provided with a plurality of blue-light LED chips; a spherical lens is arranged on an outer cover of the substrate; and a rare-soil fluorescent powder coating or a quantum-point fluorescent powder coating is coated on an incident plane in the spherical lens. The white-light LED light-emitting module disclosed by the invention has the advantages that the spherical lens is additionally arranged outside the substrate, a light output angle is enlarged and can reach to more than 300 DEG, and simultaneously, the light efficiency is increased; and the combination of the blue-light LED chips and the lens is adopted, the rare-soil fluorescent powder coating or the quantum-point fluorescent powder coating is coated on the incident plane in the spherical lens, and then white light can be obtained.
Description
Technical field
The present invention relates to the LED lamp, particularly a kind of white light LEDs illuminating module.
Background technology
The LED lamp is as a kind of novel high-efficiency and energy-saving light source; Just use in large-scale promotion at present, because the LED particle is typical point-source of light, light output angle is little; Local light intensity is higher; Cause discomfort for people's vision,, reduce the luminous efficiency of product if it is logical to adopt conventional light diffusion technique can lose light again.
Summary of the invention
The present invention has overcome the deficiency that exists in the above-mentioned prior art, and the white light LEDs illuminating module of a kind of high light efficiency, the output of wide-angle light is provided, and this module not only can be applied to various LED lamps, can also reach the illuminating effect of incandescent lamp.
Technical scheme of the present invention is achieved in that
A kind of white light LEDs illuminating module comprises substrate, on substrate, is provided with a plurality of blue-light LED chips, outside substrate, is covered with sphere lens, is coated with fluorescent RE powder coating or quantum dot fluorescence powder coating on the plane of incidence in sphere lens.
Adopted the invention has the beneficial effects as follows of technique scheme:
Sphere lens has been installed in the present invention additional outside substrate, increase the light output angle, and the light output angle can reach more than 300 °, has improved light efficiency simultaneously; And the present invention adopts blue-light LED chip and combination of lenses, applies fluorescent RE powder or quantum dot fluorescence powder on the plane of incidence in lens, can obtain white light.
Description of drawings
Fig. 1 is a structural representation of the present invention.
