Abstract
The utility model discloses a light emitting diode (LED) light source. The LED light source comprises an LED chip, and is characterized by also comprising an LED bracket, wherein the LED bracket is provided with two pins; the LED chip is in circuit connection with the two pins on the LED bracket through metal wires and is adhered on the LED bracket through a high-heat-conductivity adhesive; a transparent adhesive layer is directly packaged on the LED chip; and fluorescent adhesive layers of different colors are also packaged on the transparent adhesive layer. The LED light source has the advantages of improving a lighting effect and a color rendering index of an LED and more easily controlling a color temperature range, along with high color consistency.
Description
Technical field
The utility model relates to the led light source technical field, particularly a kind of led light source.
Background technology
Under the background that the worry of current global energy shortage raises once again, energy savings is the important problem that we shall face future, at lighting field, the application of LED luminous product is just attracting common people's sight, LED has numerous advantages such as light efficiency height, long service life, energy-saving and environmental protection, more and more widely be applied to various fields, as room lighting, outdoor lighting, backlight, medical treatment, traffic and special lighting etc.People as excitation source, excite blue-light LED chip YAG fluorescent material to obtain gold-tinted at present, and the remaining blue light of gold-tinted and blue-light LED chip is mixed into white light LEDs again.This white light LEDs colour rendering under high luminance relay tender feeling condition is higher, but light efficiency descends to some extent, because YAG fluorescent powder grain diameter is bigger at present, the viscosity of glue is lower, causes the fluorescent material precipitation very fast like this, the difficult control of reference color temperature.Under low colour temperature, colour rendering is poor, color departs from the requirement of general lighting greatly, in order to address this problem, usually the LED red fluorescence powder is joined in the bloom, so as to the raising colour rendering index, but because red fluorescence powder and yellow fluorescent powder ratio differ bigger, it is unusual to be prone to excessive or other irregular colours of colour temperature deviation etc., to the higher difficult volume production of technological requirement.
Summary of the invention
The utility model provides a kind of LED of raising light efficiency and colour rendering index, and reference color temperature is easier to control, the led light source that the led light source colour consistency is good.
The utility model is achieved through the following technical solutions:
A kind of led light source, comprise led chip, it is characterized in that: described led light source also comprises led support, on led support, be provided with two pins, led chip is connected with two pin circuitry on the led support by plain conductor, led chip is bonded on the led support by high-heat-conductivity glue, directly is packaged with substratum transparent on led chip, also is packaged with the fluorescence glue-line of different colours at substratum transparent.
Described led chip is purple chip or ultraviolet light chip, and the fluorescence glue-line that is encapsulated in the different colours on the substratum transparent is followed successively by blue-fluorescence glue-line, green fluorescence glue-line and yellow fluorescence glue-line.
Described led chip is a blue chip, and the fluorescence glue-line that is encapsulated in the different colours on the substratum transparent is followed successively by yellow or green fluorescence glue-line, red fluorescence glue-line.
The utility model compared with prior art has the following advantages:
1) led light source is by encapsulating substratum transparent earlier on led chip, on substratum transparent, encapsulate the fluorescence glue-line of different colours again, thereby change the refractive index of led chip, improve the efficient of led light source, employing is away from the encapsulating structure of fluorescent material, and less led light source color is drifted about.
2) led light source can be allocated the led light source high-color rendering by different viscosities glue and different colours fluorescent material, the color saturation height, and colour gamut covers wide.
3) adopt the encapsulation of different colours fluorescent material on the led light source, the fluorescent material of every kind of color can encapsulate according to actual conditions, and the colour temperature of LED lamp can be regulated and control by the fluorescent glue of different colours fluorescent material or different-thickness, and the regulation and control of LED colour temperature are convenient, high conformity.
4) ground floor is packaged with transparent glue on the led chip, and this is to adopt the method for led chip away from fluorescent material, reduces the led chip heating fluorescent material generation look is floated and the light decay influence, reduces light decay and prolongs the LED life-span.
