Abstract
The utility model discloses an LED (Light Emitting Diode) lamp which comprises an LED chip and a lens arranged outside the LED chip, wherein the LED chip is a blue-light LED; the lens is a yellow fluorescent lens and shaped like a plate, a regular sphere, a regular hemisphere, an irregular sphere or an irregular hemisphere; part of the light emitted by the blue-light LED penetrates through the fluorescent lens to form orange-yellow light; and the orange-yellow blue is combined with other blue light to obtain white light so that white illumination light can be obtained by using a common blue-light LED chip. The LED lamp is simple, practical, low in cost and free of aberration.
Description
Technical field
The utility model relates to a kind of lighting, particularly a kind of LED lamp based on blue-light LED chip.
Background technology
In recent years, the GaN base characteristics that blue-ray LED is long because of its life-span, luminous efficiency is high, the application in fields such as stop-light, large tracts of land display screens reaches its maturity, and also begins progressively to enter the normal domestic use lighting field.Because what home lighting needed is white light source, and blue LED lamp sends is blue light, therefore need add special phosphor substance in the packing material of blue-ray LED, and mutual combination just can obtain white light, cause this LED that emits white light with high costs, practicality is lower.
The utility model content
The purpose of this utility model provides a kind of white LED lamp based on GaN base blue-ray LED.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of LED lamp, and comprise led chip and be located at the outer lens of led chip, described led chip is a blue-ray LED, described lens are yellow fluorescence lens.
Wherein, described lens are plate.
Wherein, described lens are the sphere or the hemispherical of rule.
Wherein, described lens are irregular sphere or hemispherical
The beneficial effects of the utility model are: the light partial penetration fluorescence lens that blue-ray LED sends, form orange-yellow light, these orange coloured light and the combination of other blue light have just obtained white light, use common blue-light LED chip just can obtain white illumination light, simple and practical, cheap and no color differnece like this.
Description of drawings
Fig. 1 is the structural representation of the utility model first embodiment;
Fig. 2 is the structural representation of the utility model second embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
With reference to shown in Figure 1, the utility model discloses a kind of LED lamp, comprise led chip 5 and be located at led chip 5 lens 3 outward, described led chip 5 is a blue-ray LED, described lens 3 are yellow fluorescence lens, as first embodiment, described LED lamp is a shot-light, comprise lamp socket 1 and be fixed in reflector 2 on the lamp socket 1, lamp socket 1 is provided with circuit substrate 4, is fixed with blue-light LED chip 5 on the circuit substrate 4, is fixed with lampshade on the reflector 2, described lampshade opening part is provided with yellow fluorescence lens 3, and these lens 3 are plate.
With reference to shown in Figure 2, described LED lamp is the ball lamp, comprises support 6 and is located at blue-light LED chip 5 on the support 6, the fluorescence lens 3 of the yellow of the well-regulated sphere of led chip 5 outer packages.
In addition, lens 3 can also be the hemispherical, taper shape of rule, cylindrical or the like other regular shapes, also can be irregular other three-dimensional shapes, in the actual production in packaging plastic mixed fluorescent powder, injection mo(u)lding can obtain yellow fluorescence lens.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
Claims (4)
