Abstract

The utility model relates to a discrete LED (Light Emitting Diode) white light module. The discrete LED white light module comprises an aluminum substrate, blue light emitting LED chips, metal wires and lenses, wherein the blue light emitting LED chips are cured on the aluminum substrate through roasting, the lenses are located right above the blue light emitting LED chips on the aluminum substrate and fixed with clamping grooves of the aluminum substrate through locating columns, fluorescent powder layers are respectively coated on the internal walls of the lenses, and the lenses are made from optical glass with high light transmittance. The discrete LED white light module disclosed by the utility model has the characteristics of good heat radiating effect, long service life, light uniformity, little brightness decay and high temperature resistance.

Description

Discrete LED white light module

Technical field

The utility model relates to a kind of discrete LED white light module.

Background technology

Along with the energy-saving and emission-reduction notion is rooted in the hearts of the people, LED is as green energy resource, and especially the white light LEDs product is widely used at lighting field.Present each manufacturers produce method all is around the blue-light-emitting led chip, to apply fluorescent material to excite and form.White light LEDs luminous component of the prior art is an assembling blue-light-emitting led chip on the common LED support, around the blue-light-emitting led chip, applies fluorescent material and converts white light to, and in addition silica gel or the real envelope of epoxy form; Be close to the blue-light-emitting led chip because of fluorescent material, its radiating effect is poor, brightness is prone to decay, easy to change, can't satisfy the user to requirements such as blue white light LEDs life of product are long, high temperature resistant.

Summary of the invention

The purpose of the utility model just provides the discrete LED white light module that a kind of good heat dissipation effect, light decay are few, high temperature resistant, the life-span is long white light conversion parts separate with luminous component.

The discrete LED white light module of the utility model; Comprise aluminium base, blue-light-emitting led chip, spun gold, lens; Blue-light-emitting led chip baking-curing is on aluminium base, and lens are positioned at directly over the emitting led chip of aluminium base blue, and lens are fixed through reference column and aluminium base draw-in groove; The lens inwall applies layer of fluorescent powder, and lens adopt the optical glass of high transmission rate.

The discrete LED white light module of the utility model compared with prior art has the following advantages:

1, good heat dissipation effect, life-span are long, because of discrete LED white light module directly is bonded in aluminium base with the high heat conducting nano elargol with the blue-light-emitting led chip, directly dispel the heat through aluminium base; Area of dissipation increases; Effective, increase obviously longer service life than common LED product radiating effect;

2, light is even, carries out the light conduction through attaching lens outward, can directly become surface-emitting type LED with putting light emitting-type LED, has solved that the common LED interior space can't evenly illuminate and the night vision picture is crossed bright and " flashlight effect " that both sides are dark excessively in the middle of forming;

3, light decay is little, high temperature resistant, and this technology is separated the blue-light-emitting led chip with fluorescent material, makes fluorescent material can not be difficult for decay because of blue-light-emitting led chip conductive exothermal is influenced by it, and is high temperature resistant;

4, because of LED white light conversion parts separate with blue-light-emitting LED luminous component, assembling is simple, can be through selecting no white light conversion parts to obtain demands of different LED white light module on identical blue-light-emitting LED luminous component basis.
