Further, the blue light of 440nm is maximum to the injury of eyesight in blue light, as further prioritization scheme, this reality
Example is applied also using the relative spectral power of 440nm blue light as optical parameter to be detected.The case where blue light color ratio is lower than 5.7%
Under, the relative spectral power of 440nm blue light is lower than 0.65.This is that existing eyeshield electronic equipment is difficult to realize.Existing " shield
Eye " electronic product, blue light color ratio is although lower, but wherein injures the inhibition of maximum 440nm blue light and unknown to human eye
Aobvious, eye-protecting function is very little.And other wavelength band components in blue light are necessary visual acuity, significantly inhibit blue light not
Only eyeshield effect is unobvious, can also cause adverse effect to the visual acuity of the crowds such as children, child, such as due to blue light ingredient
Excessive missing, lead to anomalous trichromatism, the problems such as chromatic discrimination power declines.The present embodiment blue light color ratio is reduced to it is 5.7% below
On the basis of, emphasis inhibits the intensity of 440nm blue light, can really play the role of protecting eyesight.

Property difference problem, meanwhile, so that different product when colour temperature is identical be in same BIN, colour temperature consistency is good.
In addition, flip-chip but also the volume of white-light emitting unit 4221 further decreases, is conducive to dimension of light source control
System.In the present embodiment, the width of white-light emitting unit 4221 is less than 0.8mm, is highly less than 0.3mm, red light-emitting unit
4222 can be controlled in same range.Adjacent white-light emitting unit 4221 and 4222 spacing of red light-emitting unit is 1mm or less.
The length of this light source is less than or equal to 6mm, and width is less than 3mm.
Certainly, the utility model is not limited to using flip-chip, is also feasible using positive cartridge chip.
In one embodiment of the utility model, base part 421 is preferably the lamellar structure of nonmetallic materials production, base
Base accessory 421 is equipped with reflector 4211, and white-light emitting unit 4221, red light-emitting unit 4222 are set in reflector 4211,
Circuit 423 is formed in the surface of base part 421, and is wrapped in the tow sides of base part 421, and in the shape of reflector 4211
At pin, the bottom exposed portion circuit 423 of reflector 4211 is used for and white-light emitting unit 4221 and red light-emitting unit
4222 connections.
Further, the inner wall of reflector 4211 is equipped with reflective surface 4212, is also filled with encapsulation inside reflector 4211
Colloid (not shown), reflective surface 4212 is for reflecting white light and feux rouges, and packing colloid is for protecting in reflector 4211
Portion's structure and keep light-source structure more stable, and refraction adjustment is carried out to light.White light and feux rouges be sufficiently mixed after by encapsulation
Colloid output.Specifically, the light emitting angle of white-light emitting unit 4221 and red light-emitting unit 4222 can be for 160 ° or so extremely
180 °, the light-emitting angle of light source is 120 ° or so.Entire light source is the quasi- natural light lamp bead of small-sized uniformly light-emitting.
In the present embodiment, circuit 423 has several groups positive and negative anodes pin, can the corresponding one group of positive and negative anodes of each illuminator
Pin or the corresponding one group of positive and negative anodes pin of several illuminators.In driving method, there are two types of embodiments, first, white light is sent out
Light unit 4221 and red light-emitting unit 4222 are separately connected different positive and negative anodes pins, are operated alone, at this time respective driving
Electric current is different, and control chip can be cooperated to be controlled.Second, white-light emitting unit 4221 and red light-emitting unit 4222 are gone here and there
Connection, that is, connect identical positive and negative anodes pin, and unified same current driving is not required to control chip and is controlled.
With reference to Fig. 5 and Fig. 6, two white-light emitting units 4221 and a red light-emitting unit 4222 are connected, two white lights
Luminescence unit 4221 is separately connected first pin 424, and 424 self-reflection cup of the first pin, 4211 bottom is stretched out, for connecting
External power supply.Red light-emitting unit 4222 is series between two white-light emitting units 4221.
Further, which is also provided with second pin 425, which is not used in connection external power supply,
But be used to radiate, and promote the symmetry of light source entirety, the stability for promoting intensity and being installed on 423 plate of circuit.
In above-described embodiment, obviously there is apparent advantage by the way of unified driving, does not need for different hairs
Body of light configures different driving currents, does not need to increase control circuit, it is only necessary to power according to its corresponding electric current.Cause
This, more simplified in structure, volume further decreases, and application is easier flexibly, and cost is lower.This is excellent for the utility model
The circuit connection scheme of choosing.
By a large amount of process of experimental, it is determined that the luminous flux and red light-emitting unit of white-light emitting unit 4221
The actual ratio of 4222 light radiation is 2-3:1, and electric current is between 20-100mA, preferably 60mA.It is preferred that 1-4 white light hair
4222 in series light sources of light unit 4221 and 1-2 red light-emitting unit, the power of single light source are 0.5W or so.Color
In the case where warm difference, real data is slightly different.It can according to need the corresponding data for determining several colour temperatures, manufacture corresponding produce
Product.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
