Abstract

The utility model discloses red, green and blue colour picture elements, which comprises a red, green and blue colour light emitting device, a printed board component and an outer cover. The colour light emitting device can be a colour bulb; the exterior of the bulb is provided with a reflecting bowl. The colour light emitting device can also be a combination of a red, a green light emitting diodes and a blue bulb; the exterior of the blue bulb is provided with a reflecting bowl. The utility model is used as an electronic display screen of a light emitting device for displaying the information of advertisements, securities, scores in the stadiums, etc. The utility model has the advantages of rich color, vividness and low cost.

Description

Red green blue color pixel

The utility model relates to a kind of luminescent device, particularly relates to a kind of red green blue color pixel.

Pixel is the luminescent device of electronic display, color pixel is divided into two kinds of pseudo-colours and true color, the pseudo-colours pixel is made up of red green two kinds of primary colours, the true color pixel is by red, green, blue three kinds of primary colours are formed, international and domestic employed true color pixel mainly is the picture dot pipe at present, but the picture dot pipe costs an arm and a leg, do electronic display with this first control, the cost of its great number makes the user be difficult to bear, and the LED pixel has only pseudo-colours at present, and the true color pixel pipe does not form product as yet, and reason is that prices are rather stiff for the blue pipe of LED, with the electronic display that the pseudo-colours pixel is manufactured, its display effect is inferior to the screen of true color pixel as luminescent device far away.

The purpose of this utility model is: a kind of red, green, blue light luminance brightness height is provided, manufactures true color pixel with low cost.

Following mode can realize the utility model:

Red green blue color pixel comprises red, green, blue chromatic illuminating device, and printed board assembly and outer cover, described chromatic illuminating device are red, green, blue colored electric lamp bulb, are provided with reflector outside bulb; Perhaps chromatic illuminating device is the combination of red, green LED and blue light bubble, is provided with reflector outside the blue light bubble.

The utility model adopts the structure that reflector is set outside bulb, its display brightness height, color is true to nature, effect near color TV, when being luminescent device with the colour lamplight, every pixel price only is 20% of a picture dot pipe, and the pixel of blue light light and LED combination had both remedied the not enough defective of LED blue light luminance brightness, overcome the too high deficiency of LED blue pipe price again, the price of combination pixel is that all true color pixels are minimum at present.

Fig. 1 is to be the pixel structure front view of luminescent device with red, green, blue light bubble;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is that red, green LED and blue light combination pixel structure are arranged synoptic diagram.

Embodiment 1:

As illustrated in fig. 1 and 2, printed board assembly 4 is housed in outer cover 1, the 5th, the exit of printed board assembly 4, evenly distributed above assembly 4 have red, a green blue lampion 6, each lamp is provided with reflector 2 outward, reflector 2 adjacent gardens are tangent, and the space between the reflector 2 is an insulation filler 3, also can directly be processed into reflector to insulation filler 3.

Embodiment 2:

Shown in Figure 3 is that the combined type pixel structure is arranged synoptic diagram, 7 is red, green LEDs among the figure, the 8th, blue light, outside the blue light bubble, reflector 2 is set, be insulation filler 3 between light emitting diode 7 and reflector 2, can directly be processed into reflector 2 to insulation filler equally, the reflector surface is done light and is handled, the structure of present embodiment is 8 light emitting diodes and 4 blue light combinations, also can be the combination of the LED and the blue light of other number.

Claims

1, a kind of red green blue color pixel comprises red, green, blue chromatic illuminating device, printed board assembly and outer cover, and it is characterized in that: red, green, blue chromatic illuminating device is a colored electric lamp bulb, is provided with reflector outside bulb; Perhaps red, green blue chromatic illuminating device is the combination of red, green LED and blue light bubble, is provided with reflector outside the blue light bubble.

2, red green blue color pixel according to claim 1, it is characterized in that: the adjacent garden of reflector is tangent.
