Abstract

The utility model discloses an illuminator device with long service life, low temperature, less power consumption and compatibility with both AC and DC. The utility model comprises at least one two-way LED, a voltage-reducing resistor (R2), a shunt resistor (R1), and a filter capacitor (C1). Said two-way LED is constituted by arranging two common LED chips in reverse polarity manner and packing as a whole. The illuminator device has advantages of long service life (100 times of that of the common incandescent bulb or peanut bulb), small thermal value, less power consumption, resistance to vibration, and compatibility with both AC and DC, and is widely used in various places in need of illumination.

Description

A kind of light-emitting device

Technical field

The utility model relates to a kind of light-emitting device.

Background technology

The instructions for use of aircraft components is extremely strict, and especially the requirement to failure rate will reach 10 on safety ^-6Reliability.In the prior art, the instrument face plate back lighting device that aircraft handling storehouse and seat storehouse are used, usually use incandescent lamp bulb (or small electric bulb), incandescent lamp bulb (or small electric bulb) has following shortcoming: after taking off, because the influence of machine movement such as air-flow and engine, can produce certain dither, the tungsten filament of incandescent lamp is damaged easily, tend to shorten the useful life of incandescent lamp; Incandescent indicator light produces a large amount of heat energy when operate as normal, not only scald one's hand, and long term high temperature work is also unfavorable to the service behaviour of airborne equipment; Incandescent indicator light produces a large amount of heat when overcurrent burns out, also can burn to distortion the explosion of glass housing even the glass housing sometimes; Incandescent indicator light life-span weak point needs often to keep in repair and change, and as breaking down when flying, can influence flight safety ...There are a lot of good light-emitting devices can replace incandescent lamp bulb (or small electric bulb) at present, thereby improve its performance and life-span, for example: the LED light-emitting diode, its life-span is 100 times of incandescent lamp bulbs (or small electric bulb), colourity can accomplish that with light efficiency temperature is very low with incandescent lamp is identical, and energy antivibration and very power saving, still, this LED light-emitting diode can only use DC power supply.

In sum, the present instrument face plate back lighting device used of light-emitting device, especially aircraft handling storehouse of using in the prior art and seat storehouse, exist the life-span short, caloric value is big, power consumption is big, the suitable single defective of power supply.

The utility model content

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and the light-emitting device that a kind of life-span is long, caloric value is little, power consumption is little, alterating and direct current is general is provided.

The technical scheme that the utility model adopted is: a kind of light-emitting device, it comprises one or more two-way LED and dropping resistor, shunt resistance, filter capacitor, described dropping resistor is connected between described two-way LED and power supply, described shunt resistance and filter capacitor are in parallel with described two-way LED, and described two-way LED is packaged as a whole then by two common LED wafer positive and negative electrode reverse parallel connections.

Used crystal chip adopts the blue-light-emitting wafer among the described two-way LED, and the phosphor powder layer in the used encapsulating material is red and yellow mixed fluorescent powder layer, and the reference color temperature of described two-way LED is: X=0.470-0.490, Y=0.440-0.460.

The beneficial effects of the utility model are: the utility model adopts two-way LED, and described two-way LED adopts two common LED wafer positive and negative electrode reverse parallel connections to be packaged as a whole then, and it has the following advantages:

1, because LED can adopt low-voltage power supply, so insulating requirements is not high, does not need annexes such as transformer, ballast, starter, obviously reduces investment outlay;

2, because LED is simple in structure, belong to solid light source, therefore do not need inflation, do not need glass shell, also do not have problems such as air seal, and shock-resistant, and vibration resistance is difficult for broken;

3, because LED is a cold light source, so controllability is good, and the response time is fast, and frequently light on and off repeatedly can be not tired;

4, because the color of led light source is pure, abundant, also can develop arbitrary hue, so it is ornamental unrivaled;

5, because led light source light structures, volume are small and exquisite, can adapt to multiple physical dimension and different space sizes, to the requirement of light fixture strength and stiffness than other electric light sources require low, therefore applied widely, can be used for conventional Landscape Lamp, as garden lamp, Lamp for public place of entertainment, Lawn lamp, wall lamp, contour of building lamp, small-sized shot-light, road shunting lamp, underground lamp, mine lamp or the like;

6, owing to the led light source exquisiteness, flexibility is good, therefore can form shapes such as multiple point, line, ball, face, and by microcomputer-based intelligent chemical control system technology, control flickering (flicker) forms " point, line " effect; Control gradual change (the gentle change) forms " face " effect; Moving (jump), vertical, the horizontal dynamic variation effect of formation pattern of becoming of control; In addition, more than three kinds of variations also can form the rotate effect of spheroid, also can accomplish single lamp control and the control of group's lamp;

7, because the energy consumption of LED is low, single tube power under the situation that forms equal illuminating effect, its power consumption have only incandescent lamp 1/8th, fluorescent lamp 1/2nd, so energy-saving effect is very obvious;

8, because the long service life of led light source, its life-span is 100 times of incandescent lamp, 20～30 times of fluorescent lamp, therefore the hardship of having removed frequent maintenance from;

Therefore 9,, can alterating and direct current general because the utility model adopts two-way LED.

So the utlity model has the advantage that the life-span is long, caloric value is little, power consumption is little, alterating and direct current is general.

Embodiment

As shown in Figure 1, the utility model includes one or more two-way LED and dropping resistor R2, shunt resistance R1, filter capacitor C1, described dropping resistor R2 is connected between described two-way LED and power supply, described shunt resistance R1 and filter capacitor C1 are in parallel with described two-way LED, and described two-way LED is packaged as a whole then by two common LED wafer positive and negative electrode reverse parallel connections.

Used crystal chip adopts the blue-light-emitting wafer among the described two-way LED, and the phosphor powder layer in the used encapsulating material is red and yellow mixed fluorescent powder layer, and the reference color temperature of described two-way LED is: X=0.470-0.490Y=0.440-0.460.

In the present embodiment, dropping resistor R2 and shunt resistance R1 play control and stabilized illumination brightness; 1 pair of power filter of capacitor C can be cut down the power supply peak value, protection LED; Fuse carries out overcurrent and short-circuit protection to circuit.

The utility model can be used for the back lighting device of the instrument face plate in aircraft handling storehouse and seat storehouse, has the advantage that the life-span is long, caloric value is little, power consumption is little, alterating and direct current is general.

Certainly the utility model also can be widely used in the luminous place of various needs.
