Description

50-100 watt of illuminative high-power LED

Technical field

The utility model relates to a kind of great power LED, especially relates to a kind of 50-100 watt illuminative high-power LED.

Background technology

Existing light fixture comprises incandescent lamp, common fluorescent lamp and LED light fixture etc., common fluorescent lamp is a gaseous discharge lamp, the photoelectric conversion efficiency of common fluorescent lamp is than incandescent lamp height, yet common fluorescent lamp requires high to operating ambient temperature, is not easy to start when temperature is low, heat is given birth in argon gas ionization during use in the common fluorescent lamp, thereby make mercury generation steam and send strong ultraviolet ray, common fluorescent lamp glimmers easily, influences user's eyesight.In addition, when the fluorescent tube of common fluorescent lamp when breaking, the luminescent substance that flows out in it pollutes the environment and the mankind is damaged.

LED is a kind of solid state device that electric energy is converted into luminous energy, its structure mainly is made up of PN junction wafer, electrode and optical element, the basic functional principle of LED is when a forward bias voltage puts on the PN junction two ends, because the reduction of PN junction potential barrier, the positive charge in P district will spread to the N district, the electronics in N district forms the accumulation of non-equilibrium electric charge simultaneously also to the diffusion of P district in two zones.Because charge carrier is unstable relatively, thereby hole and electron recombination, wherein unnecessary energy with the form of light to external radiation, the energy difference in electronics and hole is big more, the photon energy that produces is just high more, energy is differential to vary in size, and it is just different with wavelength to produce light frequency, and the color relation of corresponding light can be different.Advantages such as great power LED has the energy conversion efficiency height, on-off effect speed is fast, the life-span long, radiationless and low in energy consumption and being employed.Yet, because existing great power LED conversion efficiency is low, also be confined to some special fields, also fail in the lighting field extensive use.

Summary of the invention

The utility model is the 50-100 watt of illuminative high-power LED that a kind of light extraction efficiency of the LED of increasing wafer is provided at the defective that the above-mentioned background technology exists.

For achieving the above object, the utility model discloses a kind of 50-100 watt illuminative high-power LED, it comprises radiator, and described radiator is provided with some location holes.Described radiator middle part is provided with the LED wafer, and described LED wafer scribbles one deck silica gel matter fluorescent material, and an end of described LED wafer is electrically connected with first electrode, and the other end of described LED wafer is electrically connected with second electrode, and described LED wafer seals by silica gel.

Further, described location hole is positioned on four angles of described radiator.

Further, described radiator is heat radiation copper seat.

In sum, the utility model 50-100 watt illuminative high-power can increase the light extraction efficiency of LED wafer, and more near the demand of illuminating product, more energy-conservation 60% than traditional bulb, the life-span is 10 times of common bulb.

Description of drawings

Fig. 1 is the stereogram of a kind of embodiment of the utility model.

Fig. 2 is a structural representation of the present utility model shown in Figure 1.

Embodiment

For further understanding feature of the present utility model, technological means and the specific purposes that reached, function, the utility model is described in further detail below in conjunction with accompanying drawing and embodiment.

See also Fig. 1 and Fig. 2, the utility model 50-100 watt illuminative high-power LED comprises radiator 1, described radiator 1 is provided with some location holes 11, described location hole 11 is positioned on four angles of described radiator 1, thereby when being assembled into light fixture, by described location hole 11 plug with aluminium base on or the screw that is connected of radiator, just be fixed on the utility model on the aluminium base reliably or on the radiator.Described radiator 1 middle part is provided with LED wafer 2, and described LED wafer 2 scribbles one deck silica gel matter fluorescent material.

One end of described LED wafer 2 is electrically connected with first electrode 3, and the other end of described LED wafer 2 is electrically connected with second electrode 4, and described LED wafer 2 seals by silica gel 5.After described silica gel 5 sealings, just waterproof.In the present embodiment, described radiator 1 is heat radiation copper seat, thereby the heat derivation that can fast LED wafer 2 be produced, and then improves useful life of the present utility model.

In sum, the utility model 50-100 watt illuminative high-power can increase the light extraction efficiency of LED wafer 2, and more near the demand of illuminating product, more energy-conservation 60% than traditional bulb, the life-span is 10 times of common bulb.

The above embodiment has only expressed a kind of execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with claims.
