Description

LED

Technical field

The utility model belongs to LED field, specifically a kind of LED.

Background technology

LED is English light emitting diode（Light emitting diode）Abbreviation, its basic structure is one piece Electroluminescent chip of semiconductor material, with elargol or latex solidified to support, then with silver wire or gold thread connection chip and Circuit board, then surrounding sealed with epoxy resin, play a part of protect internal core, shell is finally installed, so LED lamps Anti-seismic performance it is good.In terms of being related to the daily household electrical appliances such as mobile phone, desk lamp, household electrical appliances and machinery production with field.

Initial LED is used as the instruction light source of instrument and meter, and later various photochromic LED are aobvious in traffic lights and large area It is widely applied in display screen, generates good economic benefit and social benefit.With 12 inches of red traffic light Exemplified by, it was to use the long-life originally in the U.S., 140 watts of incandescent lamps of low luminous efficacy are as light source, and it produces 2000 lumens White light.After Red lightscreening plate, the feux rouges of light loss 90%, only remaining 200 lumens.And in newly-designed lamp, Lumileds is public Department employs 18 red LED light sources, including circuit loss, 14 watts of power consumption altogether, you can produce same light efficiency.Automobile is believed Signal lamp is also the key areas of LED/light source application.

For general illumination, light source of the people with greater need for white.The LED emitted white light for 1998 is succeeded in developing.It is this LED is by GaN chips and yttrium-aluminium-garnet（YAG）It is packaged together and makes.GaN chip blue light-emittings（λ p=465nm, Wd= 30nm）, the YAG fluorescent powder containing Ce3+ that high temperature sintering is made sends sodium yellow after being excited by this blue light and penetrates, peak value 550nLED lamps m.Blue-ray LED substrate is arranged in bowl-type reflection cavity, covers to be mixed with YAG thin resin layer, about 200-500nm.LED substrates The blue light components sent are absorbed by fluorescent material, and another part blue light is mixed with the gold-tinted that fluorescent material is sent, and can obtain white light.

For InGaN/YAG White LEDs, by changing the chemical composition of YAG fluorescent powder and the thickness of regulation phosphor powder layer, Colour temperature 3500-10000K assorted white light can be obtained.This method that white light is obtained by blue-ray LED, simple structure, cost Cheap, technology maturity is high, therefore with most.

Due to the high directivity of LED light, light distribution angle is not big enough, in order to meet the various demands of illumination, it is necessary to increase light Irradiation angle, and in the place such as meeting-place or stage, it is necessary to make the power of light change with different directions.

Utility model content

In order to solve the above-mentioned technical problem, the utility model provides a kind of LED.

A kind of LED, it is characterised in that include the lampshade of a spheroidal, a footstock, top are set at the top of lampshade The bottom of seat is provided with LED/light source, and the bottom of lampshade is provided with reflector, and the top of the reflector is tapered, reflector Surface is provided with several loopholes, and the both sides of lampshade are provided with reflecting plate, and the reflecting plate is circular arc and and lampshade Side wall be engaged.

Described a kind of LED, it is characterised in that the bottom of footstock is provided with an encapsulating shell, the bag in the lampshade Capsule is transparent or semitransparent, and encapsulating shell is in circular arc, and its thickness is gradually decreased from centre to both sides.

Described a kind of LED, it is characterised in that the reflector has one or more, the LED/light source also have 1 or Multiple, the top of at least one reflector is corresponding with the center line of at least one LED/light source.

Described a kind of LED, it is characterised in that the reflecting plate has 2 or multiple, and reflecting plate is in the both sides pair of lampshade Claim distribution.

Described a kind of LED, it is characterised in that the drift angle of the reflector is 90 degree -120 degree.

Described a kind of LED, it is characterised in that the encapsulating shell integrally covers the LED/light source, the encapsulating shell and lamp Cover top is integrally formed.

Described a kind of LED, it is characterised in that the lampshade is resin lampshade.

LED of the present utility model, using special structure, significantly increases the lighting angle of LED, and improve Colour temperature, the power of light changes with different directions, is adapted to the place such as meeting-place or stage and uses, more energy-conserving and environment-protective.

Embodiment

The utility model is described in detail below in conjunction with the accompanying drawings.

As shown in figure 1, LED of the present utility model, includes the lampshade of a spheroidal, one is set at the top of lampshade Footstock, the bottom of footstock is provided with LED/light source, and the bottom of lampshade is provided with reflector, and the top of reflector is tapered, reflector Surface be provided with several loopholes, the both sides of lampshade are provided with reflecting plate, reflecting plate be circular arc and with lampshade Side wall is engaged.Reflector has one or more, and LED/light source also has one or more, the top of at least one reflector with least The center line of one LED/light source is corresponding.Reflecting plate has 2 or multiple, and reflecting plate is symmetrical in the both sides of lampshade.Reflector Drift angle be 90 degree -120 degree.When LED works, the light part that LED/light source is sent passes through the loophole of reflector, one Divide and reflecting plate secondary reflection again is reflexed to by reflector, a part of light is concentrated the both sides diverging to lampshade, and can pass through Quantity, the size of loophole, the quantity and position adjustments of the angle of reflector, quantity and reflecting plate, make light it is strong and weak with Different directions and change.

The bottom of footstock is provided with an encapsulating shell in lampshade, and encapsulating shell is transparent or semitransparent, and encapsulating shell is in circular arc Shape, its thickness is gradually decreased from centre to both sides, and encapsulating shell integrally covers the LED/light source, the encapsulating shell and at the top of lampshade one It is body formed.Encapsulating shell can also play increase lighting angle, the effect for spreading light.

Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model Any modifications, equivalent substitutions and improvements made within new spirit and principle etc., are all contained in protection of the present utility model Within the scope of.
