CN202493959U - White-light LED light-emitting module - Google Patents

Abstract

The utility model discloses a white-light LED light-emitting module which comprises a base plate, a plurality of blue-light LED chips are arranged on the base plate, a spherical lens covers the base plate, and a rare-earth fluorescent powder coating or a quantum dot fluorescent powder coating are coated on the incident plane inside the spherical lens. In the utility model, the spherical lens is added outside the base plate, so that the light output angle is increased and can reach more than 300 DEG, and the light effect is improved. Moreover, the blue-light LED chips and the lens are combined and rare-earth fluorescent powder or quantum dot fluorescent powder is coated on the incident plane inside the spherical lens, so that white light can be obtained.

Description

The white light LEDs illuminating module

Technical field

The utility model 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 spot 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.

The utility model content

The utility model 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.

The technical scheme of the utility model 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 beneficial effect of the utility model of technique scheme to be:

The utility model has installed sphere lens 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 utility model adopts blue-light LED chip and lens combination, applies fluorescent RE powder or quantum dot fluorescence powder on the plane of incidence in lens, can obtain white light.
