Description
Technical field
The present invention relates to a kind of illuminator lamp bubble, particularly relate to a kind of even light mixing, be easy to the LED white light illuminating bulb adjusting colour temperature and have high color rendering.
Background technology
Because light emitting diode (Light Emitting Diode is called for short LED) has low power consuming, high efficiency characteristic and advantage, therefore present various countries and industry are all classified this technology as the focus technology of strategy development, to replace existing traditional lighting apparatus.
As shown in Figure 1, existing LED lighting bulb, be that a plurality of LED elements 1,2,3 that can send ruddiness, green glow, blue light respectively are electrically connected on the circuit board 4, connect a splicing ear (not shown) by this circuit board 4 again, with by this splicing ear and power supply or lamp socket electric connection, realize utilizing primaries (red, green, blue) to mix out the purpose that can supply illuminating white light.But this kind utilizes red, green, blue to be mixed to realize the mode of white-light illuminating, except light wavelength of all kinds will satisfy the condition that can cooperate white light, light intensity of all kinds also will have suitable proportioning, therefore on implementing, mixed light exists suitable difficulty, often only can realize following effect: white light only appears at the zone central authorities of the light beam common factor of each coloured light, away from the colour temperature of the mixed light of middle section convergence Red Green Blue light gradually, cause forming riotous with colour color lump in the field of illumination.This is the defective that the mixed light inequality is caused, and can cause illuminating effect not good.
Figure 2 shows that another kind of LED lighting bulb, it is electrically connected at a plurality of LED elements 1,2,3 that can send ruddiness, green glow, blue light respectively on one circuit board 4, connect a splicing ear (not shown) by this circuit board 4 again, and a Transparent lamp shade 5 is set before this circuit board 4, these Transparent lamp shade 5 inside then add fluorescent material (agent) 6, primaries (red, green, blue) is realized can supply illuminating white light via the mixing of fluorescent material.But this kind mode can provide the range of illumination limited, and because LED element 1,2,3 must be accompanied by high temperature in luminous, and fluorescent material 6 and non-refractories own, therefore when the temperature of LED element raises, qualitative change can take place in fluorescent material fast, cause the LED element to produce the light decay phenomenon, have a strong impact on illumination or lightness.
In addition, because the emission wavelength of LED depends on the structure of epitaxial layer and the material of composition, even relate to the problem of lattice coupling, therefore, the height of the semiconductor Yin Wendu that is caused by above-mentioned reason changes and problem that the wavelength drift takes place just can not be ignored.With regard to LED both of these case after start initial stage and energising a period of time, at the start initial stage, because the luminous efficiency of ruddiness is higher, what mixed out by this Red Green Blue light be white red partially light source; And after energising a period of time, the blue light higher along with luminous efficiency progressively strengthens, and can make the mixed light colour temperature be partial to the inclined to one side blue light of white of cold light system gradually, and therefore the colour temperature of the mixed light of gained has nothing in common with each other in both cases.From the angle of spectrum, wavelength is excessive by the heat drift scope that warm colour system moves to cool colour system, can have a strong impact on the white balance of mixed light colour temperature, and illumination intensity of light source relatively detracts.
In addition, also have a kind of LED who emits white light that utilizes to serve as main light source, and one group of color temperature compensating unit that is made of the LED that sends out red, green, blue etc. is set near white light LEDs, promptly when thereby the brightness of white light LEDs causes light decay because of the fluorescence coating qualitative change descends fast, carry out the adjustment of the current strength of single led or a plurality of LED according to the white light LEDs that decays with red, green, blue LED.But this kind mode not only can't accurately return to the standard color temperature of original white light, and need control the current strength of single or multiple LED accurately, and this also exists quite high difficulty actually, thereby does not meet the demand of economic benefit.
Summary of the invention
The technical problem to be solved in the present invention is in order to overcome the excessive defective of LED white light illuminating bulb mixed light inequality of the prior art or colour temperature drift, a kind of even light mixing to be provided, to be easy to adjust colour temperature and the better LED white light illuminating bulb of illuminating effect.
