Abstract

The utility model discloses a 1-3W illumination used high-power LED, which includes a heat sink with a T-shaped cross section, wherein the heat sink is coated with silica gel; an LED wafer is arranged at an end part of the heat sink and is coated with a layer of silica gel fluorescent powder; one end of the LED wafer is electrically connected with a first wire; and the other end of the first wire is electrically connected with a first pin. The other end of the LED wafer is electrically connected with a second wire; the other end of the second wire is electrically connected with a second pin; and a hemispherical PC lens casing covering the silica gel is arranged on one side of the LED wafer. The high-power LED can realize the increase of emergent light efficiency of the LED wafer, greatly improve the pouring efficiency of the silica gel, prevent the silica gel from outward leakage during the solidification process, save about 60% energy of the traditional bulb, and has the service life about 10 times of that of the common bulb.

Description

1-3 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 1-3 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 gas-discharge lamp, the photoelectric transformation 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 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 to provide a kind of 1-3 watt illuminative high-power LED at the defective that the above-mentioned background technology exists, and this great power LED can be realized the filling casting efficient that increases the light extraction efficiency of LED wafer and increase substantially silica gel, and silica gel does not leak in solidification process.

For achieving the above object, the utility model discloses a kind of 1-3 watt illuminative high-power LED, it comprises the radiator that cross section is T-shaped, this radiator is coated with silica gel, described radiator end is provided with the LED wafer, described LED wafer scribbles one deck silica gel matter fluorescent material, and an end of described LED wafer is electrically connected with first lead, and the other end of described first lead is electrically connected with first pin.The other end of described LED wafer is electrically connected with second lead, and the other end of described second lead is electrically connected with second pin, and described LED wafer one side is provided with the PC lens case that is dome-type that covers on the described silica gel.

Further, described first lead is gold thread or silver-colored line.

Further, described second lead is gold thread or silver-colored line.

Further, described radiator is heat radiation copper seat.

In sum, the utility model 1-3 watt illuminative high-power LED can increase the light extraction efficiency of LED wafer by adopting high transmission rate, high-strength PC as areflexia silica-gel lens shell molds, more near the demand of illuminating product.In addition, can increase substantially the filling casting efficient of silica gel, silica gel is not leaked in solidification process, more energy-conservation 60% than traditional bulb, the life-span is 10 times of common bulb.
