Abstract
A lamp bulb can generate red, blue and green lights and is composed of at least one lamp core or one group of lamp cores for different cold-cathode fluorescent lamps, a fixing device of lamp core(s), a bulb with reflector and a holder. Said lamp core(s) is installed in vacuum bulb. The lamp bulb can be used to display monochromatic, polychromatic or panchromatic charater, graph and image or to light.
Description
The present invention relates to a kind of high brightness, high efficiency, long-life colour changing bulb, particularly a kind ofly make wick, can be used for monochrome, polychrome, panchromatic character, figure and image shows and the colour changing bulb of illumination with cold-cathode fluorescence lamp.
At present prior art is extensive use of the light-emitting component of incandescent lamp bulb as big ocra font ocr, graphical display, and incandescent lamp is luminous, with not homochromy glass cell-shell by the white light colour filter to obtain not homochromy light, an a kind of color of bulb.The brightness of this kind incandescent lamp is very high, is widely used in outdoor character, graphical display at present.But there is following weakness in this incandescent lamp:
(1) luminous efficiency is low.The efficient of the incandescent lamp that for example emits white light is generally 101m/W, if with red, blue, green coloured glass bulb to obtain red, blue, green light, then its efficient on average will be lower than 31m/W, particularly blue look, if obtain the blue streak that color coordinate meets the requirement of colour TV image, then efficient is shorter.
(2) life-span short, be generally about 3000 hours, the bulb of high brightness particularly, the life-span is shorter.
(3) poor reliability, incandescent filament blows easily, more changes the bulb and the maintenance cost height.
(4) bulbs have only a kind of color, and its illuminant colour can not change.
The objective of the invention is to overcome above-mentioned shortcoming, but provide that a kind of brightness is very high, efficient is very high, the life-span is very long and bulb both bill coloured light, also can rubescent, blue, green three primary colors light and the light-emitting component of any other coloured light.It can be used for indoor, outdoor demonstration monochrome, polychrome and colored character, figure and image, also can be used for illumination.
The objective of the invention is to finish by following technical solution:
1. make wick with cold-cathode fluorescence lamp monochromatic or red, blue, green three primary colors or other any look;
2. said fluorescent lamp is bent to definite shape, makes fluorescent lamp that long length be arranged, to guarantee to have higher luminous efficiency and brightness;
3. the coloured glass pipe that not homochromy cathode fluorescent tube is used and its illuminant colour is complementary to absorb the heterogeneous light of fluorescent tube gas discharge generation, improves luminous colorimetric purity;
4. said cold-cathode fluorescence lamp wick, be sealed in the bulb, said bulb can be sphere, or its front portion is transparent sphere light exit window, anti-portion is taper or the approximate taper bulb that light reflective film is arranged, thereby can make by fluorescence wick issued light effectively from the window outgoing.
5. bulb is pumped into vacuum, thereby can reduce the thermal loss of cold-cathode fluorescence lamp, improves luminous efficiency, can eliminate the influence of ambient temperature to the bulb characteristics of luminescence simultaneously.
Description of drawings is as follows:
Fig. 1 is the structural representation of colour changing bulb of the present invention.
To describe in detail the present invention by accompanying drawing below.
Fig. 1 is the structural representation of colour changing bulb of the present invention.101 for being bent to the cold-cathode fluorescence lamp of definite shape among the figure, and it can be one or several the fluorescent lamps with a kind of color, also can be one group not homochromy or comprise the fluorescent lamp of each one red, blue, green three primary colors at least, shown in R, G, B among Fig. 1.102 is the cell-shell of bulb, and its forward part 103 is the transparent optical output window of sphere or approximate sphere.Its rear portion 104 is taper shape or approximate circle taper, and its inwall has high reflection layer 105, for example Al or Ag or other high reflectivity film.Said high reflection layer 105 can be exported fluorescent lamp backward and to the light reflection of emission all around to front window 103, to increase brightness, shown among Fig. 1 106.107 is a fixed head, and said fluorescent lamp 101 is fixed on the said fixed head 107, for example fixing with ceramic glue or low-melting glass 108 in the junction.If said fluorescent lamp 101 is more than one, then between each fluorescent lamp also useful ceramics glue or low-melting glass interfix, as among Fig. 1 109, to strengthen the mechanical strength of colour changing bulb.110 for including the lamp holder of metal lead wire 111 and blast pipe 112.Fixed head 107 is fixed on the said lamp holder 110, and is also fixing with ceramic glue or low-melting glass 113.Said lamp holder 110 and said Lamp bulb case 102 sealing-ins.To be evacuated in the cell-shell by blast pipe 112.114 is lamp socket, and said Lamp bulb case and lamp holder are fixed on the said lamp socket 114 with glue 115.Each electrode 116 of fluorescent lamp 101 is connected on each electrode contact 117 of lamp socket and on the shell of lamp socket 114 through the lead-in wire 111 in lamp holders.
The shape of said cold-cathode fluorescence lamp 101, can be " U " shape or
Shape, disc, taper or other shape have enough length to guarantee fluorescent lamp, guarantee to have higher luminous efficiency and very high brightness.
The one side towards light exit window 103 of said fixed head 107 is the high reflectance face, for example plates the high reflectance face of A1, or the diffusing surface of high reflectance, is used for the light of emission is backward reflected forwards, is penetrated by light exit window 103, to improve brightness.
The forward part 103 of said Lamp bulb case 102 can be the transparent sphere or the light output window of approximate sphere, also can be the diffusion sphere of printing opacity, to obtain the output light of good colour mixture.
The rear section inwall of said globular bulb can have highly reflecting films, reflects forwards with the light with retroeflection, highlights.
Said Lamp bulb case 102 is pumped into vacuum by blast pipe 112, thereby reduces the thermal loss of fluorescent lamp, to improve luminous efficiency, also can eliminate the influence of ambient temperature to the colour changing bulb photoelectric characteristic simultaneously, make it can be under outdoor various environment operate as normal.
Colour changing bulb of the present invention, can be used for monochrome (comprising black and white), polychrome or panchromatic character, figure or image shows, when being used for the requirement illuminant colour very high colorimetric purity arranged, when for example showing panchromatic TV image, the fluorescent tube of said cold-cathode fluorescence lamp can be used the coloured glass pipe identical with this fluorescent lamp illuminant colour, to absorb the heterogeneous light that the fluorescent tube gas discharge is produced, good colorimetric purity is arranged to guarantee issued light.
Colour changing bulb of the present invention has following advantage:
1. brightness is very high, can be used for the occasion of outdoor various illumination conditions, comprises sunshine shining directly Occasion;
2. efficient height, particularly colored light;
3. the life-span is long;
4. under the environment of various different temperatures, all can work.
