Abstract

The utility model is suitable for the technical field of a light-emitting diode (LED) and provides an LED unit and an LED lighting and displaying device. The LED unit is formed by combination of a white light LED module and an RGB (red, green, blue) three-primary-color LED module which are arranged on the same support, so that lights emitted by the three-primary-color LED module can reach white balance and then be mixed with white lights emitted by a white light LED to form uniform and soft white lights, and the emitted white lights are higher in strength. Therefore, the LED unit can be widely applied to various lighting and displaying products.

Description

A kind of LED unit, LED illumination and display unit

Technical field

The utility model belongs to the LED technical field, relates in particular to a kind of LED unit, LED illumination and display unit.

Background technology

At present, commercially available RGB three-primary color LED module generally is made up of by the red wafer of 615～620mm, the green wafer of 530～540mm and the blue light wafer of 460～470nm wavelength.Can control size respectively like this, make the luminous intensity generation respective change of each wafer, form multicolour through each wafer current.If the luminous intensity of each wafer reaches certain proportion (red: green: blue=3: 6: 1), can produce white light, realize white balance.But the white light that existing RGB three-primary color LED module produces is evenly soft inadequately, even makes the people feel dazzling.

The utility model content

The purpose of the utility model embodiment is to provide a kind of LED the unit, is intended to solve the even inadequately soft problem of white light that existing RGB three-primary color LED module produces.

The utility model embodiment is achieved in that a kind of LED unit, is combined to form by the white light LEDs of being located at same support and RGB three-primary color LED module.

Another purpose of the utility model embodiment is to provide a kind of LED lighting device, and said LED lighting device adopts above-mentioned LED unit.

Another purpose of the utility model embodiment is to provide a kind of LED display unit, and said LED display unit adopts above-mentioned LED unit.

The utility model embodiment is combined to form the LED unit by the white light LEDs of being located at same support and RGB three-primary color LED module; The light that so the three-primary color LED module is sent mixes evenly soft white light of formation with the white light of white light LEDs generation after reaching white balance; And the white light intensity of outgoing is stronger, and this sample LED unit can be widely used in various illuminations, show product.

Embodiment

For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

The utility model embodiment is combined to form RGBW four look LED unit with a white light LEDs and RGB three-primary color LED module; These RGBW four look LED unit make the RGB three primary colors reach the white light that produces with white light LEDs after the white balance to mix and can form evenly soft white light, be widely used in illumination and demonstration product.

The LED unit that the utility model embodiment provides is combined to form by the white light LEDs of being located at same support and RGB three-primary color LED module.

The LED lighting device that the utility model embodiment provides adopts above-mentioned LED unit.

The LED display unit that the utility model embodiment provides adopts above-mentioned LED unit.

Be described in detail below in conjunction with the realization of specific embodiment the utility model.

Shown in Fig. 1～3, the LED unit that the utility model embodiment provides is combined to form by the white light LEDs of being located at first hole 1 10 and the RGB three-primary color LED module 20 of being located at second hole 2, and this first hole 1 and second hole 2 are positioned at same support 3.The white light that the light that the three-primary color LED module 20 that is positioned at second hole 2 is sent reaches after the white balance with white light LEDs 10 produces mixes and forms evenly soft white light, and this sample LED unit can be widely used in illumination and demonstration product.

Usually, the white light that white light LEDs 10 sends is produced by blue-ray LED wafer 11 excitated fluorescent powders (like yellow fluorescent powder or yellow-green fluorescence powder), places first hole 1 to get final product this blue-ray LED wafer 11, and technology is simple.During making, fluorescent material is mixed behind glue, covered this blue-ray LED wafer 11.Certainly, can allocate different fluorescent glues (being mixed with the glue of fluorescent material) according to the colour temperature (like 3000K, 5000K etc.) of required white light encapsulates.After such LED unit is made, light white light LEDs 10 separately, can obtain the white light of required colour temperature.Obviously, change the fluorescent glue of different proportionings, can make the LED unit send the white light of different-colour.

Blue-ray LED wafer 11 and RGB three-primary color LED module 20 are gone up parallelly connected in electric among the utility model embodiment, so only need adjusting separately to pass through the electric current of blue-ray LED 11 wafers, can make the LED unit send the white light of corresponding bright.Further; Make red-light LED wafer 21, green light LED wafer 22 and this blue-ray LED wafer 23 of being located in second hole 2 in electric parallel with one another; Be convenient to regulate electric current, realize that RGB is full-color, can obtain the three primary colors mixed light and the monochromatic light of different color through each LED wafer.Hence one can see that, and each LED wafer is parallel connection each other in this LED unit, and is as shown in Figure 4.

In addition, the length 4～5mm of this LED unit, wide 5～6mm, high 2～3mm.Compare with existing commercially available RGB three-primary color LED module, change in size is little, makes that this LED unit applicability is wider.

Should be appreciated that the development along with the LED technology, above-mentioned white light LEDs 10 also can directly be formed by 12 encapsulation of white light LEDs wafer.During making; This white light LEDs wafer 12 and RGB three-primary color LED module 20 be located in the same hole 4 cover by transparent glue; And make them parallel with one another electric; So only need to regulate electric current separately, can make the LED unit send the white light of corresponding bright through white light LEDs wafer 12, as illustrated in Figures 5 and 6.

The utility model embodiment is combined to form the LED unit by the white light LEDs of being located at same support and RGB three-primary color LED module; The light that so the three-primary color LED module is sent mixes evenly soft white light of formation with the white light of white light LEDs generation after reaching white balance; And the white light intensity of outgoing is stronger, and this sample LED unit can be widely used in various illuminations, show product.During making, fluorescent material is mixed behind glue, covered blue-ray LED wafer formation white light LEDs, can allocate different fluorescent glues according to the colour temperature of required white light and encapsulate, light white light LEDs separately, can obtain the white light of required colour temperature.In addition, blue-ray LED wafer and RGB three-primary color LED module are gone up parallelly connected in electric, only need to regulate the electric current that passes through the blue-ray LED wafer separately, can make the LED unit send the white light of corresponding bright.

The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection range of the utility model.
