Abstract
The invention discloses a semi-conductor luminescent device with simple structure, small size, low light source waste and high integration level. The semi-conductor luminescent device comprises a semi-conductor luminescent tube and a frame plate, wherein the semi-conductor luminescent tube is formed by welding a diode chip and a divider resistor, and is arranged on the frame plate. Through the adoption of welding, the semi-conductor luminescent tube is small in occupied space, and simple in structure; as the frame plate, of which the angle is adjustable, is additionally arranged, the angle of forward light of an LED display screen can be adjusted, an observer can see contents on the screen from the bottom surface of the screen effectively, and light source waste can be reduced.
Description
Technical field
The present invention relates to a kind of semiconductor light-emitting apparatus, particularly a kind of integrated form semiconductor light-emitting apparatus.
Background technology
Semiconductor light-emitting-diode is as lighting source of new generation, have advantages such as green energy conservation, longevity, response speed be fast, be used widely gradually in applications such as view, indication, backlight and special lightings, wherein, LED display display frame is bright in luster, third dimension is strong, is widely used in public places such as station, harbour, airport, market, hospital, hotel, bank.But when LED display was positioned at the high-altitude, LED is luminous can not to be received by the ground observation person, caused the light source waste.
In addition, semiconductor light-emitting-diode is independently electronic devices and components, its rated operational voltage is about 3V, therefore in actual use, in order to guarantee that voltage equals rated operational voltage on the diode, usually need outside this diode, be connected in series a wafer resistor disc, fly-wheel diode of two ends parallel connection or Zener diode that part also can be diode outside.The diode assembly of Zu Chenging takes up room greatly like this, especially shows screen for LED, and is very inconvenient when adjust.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, volume is little, light source waste is little and integrated level is high light emitting semiconductor device.
According to an aspect of the present invention, provide a kind of light emitting semiconductor device, comprised semiconductor luminotron and frame plate, semiconductor luminotron is welded by diode chip for backlight unit and divider resistance, and semiconductor luminotron is located on the frame plate.
Its beneficial effect is that by the mode of welding, it is little that semiconductor luminotron is taken up room, simple in structure, by adding the frame plate of an adjustable angle, just can adjust the angle that LED shows screen forward light, show the screen content thereby the bottom surface observer can effectively be seen, reduce the light source waste.
In some embodiments, the frame plate downtilt angles is not more than 45 degree.
Its beneficial effect is, considers actual needs, forward light need not be greater than 45 degree to lower angle, and it is bad fixing to tilt very much.
In some embodiments, semiconductor luminotron constitutes different colours by different diode chip for backlight unit, comprises redness, blueness and yellow.
Its beneficial effect is that multiple color strengthens aesthetic feeling.
Description of drawings
Fig. 1 is the structural representation of the light emitting semiconductor device of an embodiment of the present invention.
Embodiment
The present invention is further detailed explanation below in conjunction with accompanying drawing.
Fig. 1 has schematically shown the structure according to the light emitting semiconductor device of one embodiment of the present invention.
As shown in Figure 1, light emitting semiconductor device comprises semiconductor luminotron 1 and frame plate 2.
Semiconductor luminotron 1 by diode chip for backlight unit 3 be connected in series with divider resistance 4 be welded after, be encapsulated in the housing.Semiconductor luminotron 1 is erected on the frame plate 2, and as shown in FIG., the face of frame plate 2 tilts.Thereby being connected by the conductive layer with frame plate 2 surfaces, semiconductor luminotron 1 switches on that connect can be luminous.Because led lighting is forward light, at first pass through the mode of welding, it is little that semiconductor luminotron 1 is taken up room, simple in structure, by the frame plate 2 that adds an adjustable angle, just can adjust the angle that LED shows screen forward light, show the screen content thereby the bottom surface observer can effectively be seen, reduce the light source waste.
Because semiconductor luminotron 1 is not to weld fixingly extremely on frame plate 2 fully, so frame plate 2 downtilt angles are not more than 45 degree, otherwise semiconductor luminotron 1 comes off easily.And because be mainly used in the apparent screen of LED, in the practical application, LED shows screen also seldom can be above downward 45 degree with ground observation person's angle.
In addition owing to be to be applied to LED to show screen, in order to strengthen aesthetic feeling, semiconductor luminotron 1 constitutes different colours by different diode chip for backlight unit 3, diode chip for backlight unit 3 sends optical fiber owing to excited by electric current, and the sticker that generally contains in the chip can absorb and send the light of different colours, comprises redness, blueness and yellow, such three primary colors, by the light melange effect, just can when projection, demonstrate different colors.
Be the invention process case only below, be not limited to the present invention, as long as the equivalence that those of ordinary skills do according to disclosed content is modified or changed, all should include in the protection range of putting down in writing in claims.
