Abstract

The utility model discloses an LED lighting device which comprises an installation baseplate and LEDs installed on the installation baseplate. The LED lighting device is characterized in that the LEDs comprise white light LEDs and ultraviolet LEDs. The LED lighting device can irradiate white light. Due to the presence of the ultraviolet LEDs, the light irradiated by the LED lighting device contains ultraviolet light, thus the spectrum of the light emitted by the LED lighting device is closer to the sunlight, and the color rendering property is great. In special fields in which minimal chromatic aberration should be identified, such as textile, dyeing production and other factories, the LED lighting device can be well applied.

Description

A kind of LED lighting device

Technical field

The utility model relates to a kind of lighting device, particularly relates to a kind of LED lighting device.

Background technology

Appear at first LED light-emitting diode on the market 20th century, the course through surplus 50 years has obtained noticeable rapid progress.Especially the birth of white light LEDs, the LED product has become the new product that has influence at lighting field.

The method of making white light LEDs at present has following several kinds.A kind of is the principle of utilizing three primary colors light in the colorimetry, and near placement, control is the ratio of output separately, obtains white light after the mixing with the LED of three kinds of colors of red, green, blue.Another kind is after blue light or ultraviolet light or purple LED outside apply fluorescent material, to make fluorescent material receive exciting of blue light or ultraviolet light or purple light, so obtain wide region different wave length light and be mixed into the method for white light.

Along with the extensive use of LED illuminating lamp, increasingly high to the color rendering index requirement of LED illuminating lamp.In general as long as light source is more close with sunlight (natural daylight), and the color that eyes are seen is also true to nature more.Sunlight (natural daylight) has comprised the wavelength of all light waves such as ultraviolet ray, visible rays, infrared ray; But through above-mentioned first kind of light wavelength that obtains with second method only in the visible light spectral region of 400nm-700nm; Do not comprise ultraviolet ray, infrared ray etc.; The scope of its spectrum does not have sunlight (natural daylight) wide like this, can't reach performance and the light efficiency identical with sunlight (natural daylight).Especially to distinguishing some similar color,, all can't distinguish, make very inconvenience of user, and then use the LED illuminating lamp to receive greatly restriction change color responsive sales field or manufacturing works such as white and bleaching look.

Summary of the invention

The utility model technical problem to be solved is that a kind of color rendering is good, the LED lighting device of spectral region broad.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of LED lighting device comprises and base plate is installed and is positioned at the LED that installs on the base plate that it is characterized in that: said LED comprises white light LEDs and ultraviolet LED.

Mix for ultraviolet light can be evenly distributed in the lighting device and with white light, said ultraviolet LED evenly be arranged at intervals at this white light LEDs around.

Preferably, said white light LEDs is row to be arranged, and said ultraviolet LED evenly is arranged at intervals at the both sides of this white light LEDs.

As another embodiment of the utility model, said ultraviolet LED is located between the said white light LEDs.

Preferably, said white light LEDs is arranged in two row, and said ultraviolet LED evenly is arranged at intervals between the two row white light LEDs and is row and arranges.

Preferably, the number of said white light LEDs is 1 with the number ratio of said ultraviolet LED: 1-8: 1.

In order not only to consider cost but also have color rendering preferably, the number of said white light LEDs is 3: 1 with the number of said ultraviolet LED ratio.

Compared with prior art, the advantage of the utility model is such LED lighting device, not only can shine white light; And owing to contain ultraviolet LED, contain ultraviolet light in the light that the LED lighting device is penetrated, and then the spectrum that makes the light that this LED lighting device sent is more near sunlight; And then its color rendering is also better; Distinguish the special dimension of minimum aberration at needs, in factories such as weaving, DYE PRODUCTION, can both have preferably and use.

Fig. 2 is the sketch map of another embodiment of the utility model LED lighting device.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

The LED lighting device of the utility model, as shown in Figure 1, comprise the installation base plate 1 that is installed in the housing, and be positioned at the LED that installs on the base plate 1 that this LED comprises white light LEDs 2 and ultraviolet LED 3.As shown in Figure 1, this white light LEDs is row to be arranged, and ultraviolet LED 3 is arranged in the both sides of this row white light LEDs respectively, and evenly is provided with at interval, promptly this ultraviolet LED 3 be uniformly distributed in this white light LEDs around.The ultraviolet light that makes ultraviolet LED 3 sent like this is evenly distributed in this LED lighting device, and and white light between can merge better, do not influence the illumination of white light itself.Also can be that this white light LEDs is arranged, ultraviolet LED 3 be positioned at evenly distributing of white light LEDs 2 all around.Perhaps, as shown in Figure 2, as another embodiment of the utility model; These a plurality of white light LEDs 2 can also be arranged to two row; Ultraviolet LED 3 is row and is arranged between the two row white light LEDs 2, also can be provided with at interval with white light LEDs 2 by ultraviolet LED 3, and promptly ultraviolet LED 3 is between white light LEDs 2.

Have certain ratio between the number that is arranged so that white light LEDs and ultraviolet LED like this, this ratio can be 1: 1-8: 1.Do not considering that under the condition of cost, the number of natural ultraviolet LED is The more the better, but considering that the number ratio of white light LEDs and ultraviolet LED is 3: 1, just can reach color rendering preferably under the condition of cost.

This white light LEDs 2; Can adopt ruddiness, green glow and blue-ray LED near placement; Export ratio and then the mixed light of controlling this ruddiness, green glow and blue-ray LED obtain white light LEDs; Also can be employed on the chip carrier of blue-ray LED or purple LED or ultraviolet LED and apply fluorescent material, make fluorescent material receive blue light, purple light or exciting of ultraviolet and produce the LED of white light.

Such LED lighting device not only can shine white light, and owing to contain ultraviolet LED; Contain ultraviolet light in the light that the LED lighting device is penetrated; And then the spectrum that makes the light that this LED lighting device sent is more near sunlight, and then its color rendering is also better, distinguishes the special dimension of minimum aberration at needs; In factories such as weaving, DYE PRODUCTION, can both have preferably and use.
