technical field

The invention relates to an electrodeless lamp with long service life.

Background technique

LED (Light Emitting Diode), light-emitting diode, is a solid-state semiconductor device that can convert electrical energy into visible light, and it can directly convert electricity into light. The heart of LED is the wafer of a semiconductor, and one end of wafer is attached on a bracket, and one end is negative pole, and the other end connects the positive pole of power supply, and whole wafer is encapsulated by epoxy resin. Semiconductor wafer is made up of two parts, and a part is P-type semiconductor, and hole occupies an leading position in it, and the other end is N-type semiconductor, and here mainly is electron. But time these two kinds of semiconductors couple together, between them, just form a P-N junction. When electric current acts on this chip by wire time, electron will be pushed to P district, and in P district, electron is recombined with hole, then will send energy with the form of photon, the principle of LED light that Here it is. And the wavelength of light i.e. the color of light, be determined by the material forming P-N junction.

Initially, LEDs were used as indicating light sources for instruments and meters. Later, LEDs of various light colors were widely used in traffic lights and large-area display screens, resulting in good economic and social benefits. Take the 12-inch red traffic light as an example. In the United States, a long-life, low-light 140-watt incandescent lamp was originally used as the light source, which produces 2000 lumens of white light. After passing through the red filter, 90% of the light is lost, leaving only 200 lumens of red light. In the newly designed lamp, Lumileds uses 18 red LED light sources, including circuit loss, and consumes a total of 14 watts of power to produce the same light effect. Automobile signal lights are also an important field of application of LED light sources.

For general lighting, people need more white light sources. In 1998, the LED that emits white light was successfully developed. The LED is made by packaging a GaN chip with yttrium aluminum garnet (YAG). The GaN chip emits blue light (λp=465nm, Wd=30nm), and the YAG phosphor powder containing Ce3+ produced by high-temperature sintering is excited by this blue light and emits yellow light, with a peak value of 550nm. The blue LED substrate is installed in a bowl-shaped reflective cavity, covered with a thin layer of resin mixed with YAG, about 200-500nm. Part of the blue light emitted by the LED substrate is absorbed by the phosphor, and the other part of the blue light is mixed with the yellow light emitted by the phosphor to obtain white light. For InGaN/YAG white LEDs, by changing the chemical composition of the YAG phosphor and adjusting the thickness of the phosphor layer, white light of various colors with a color temperature of 3500-10000K can be obtained. This method of obtaining white light through blue LEDs has a simple structure, low cost, and high technical maturity, so it is most widely used.

The marks of each part in the accompanying drawings are as follows: 1, the uppermost layer, 2, the middle layer, and 3, the lowermost layer.

Detailed ways

The preferred embodiments of the invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the invention can be more easily understood by those skilled in the art, so as to define the protection scope of the invention more clearly.

Wherein, the electrodeless lamp with a long service life includes a ceramic material layer in the outermost layer 1, an epoxy resin layer in the middle layer 2, and a frosted coating on the lowermost layer 3, and the ceramic material layer and the frosted coating pass through the The epoxy resin layer is bonded together, the thickness of the ceramic material layer is 1mm, the thickness ratio of the ceramic material layer, epoxy resin layer and frosted coating is 2:1:2, and the epoxy resin layer is organic Silicone resin, the thickness of the silicone resin is 2mm.

In further explanation, the ceramic material layer has 1. High efficiency and energy saving: compared with the same brightness, a 3W LED energy-saving lamp consumes 1 kilowatt-hour of electricity in 333 hours, while an ordinary 60W incandescent lamp consumes 1 kilowatt-hour of electricity in 17 hours, and an ordinary 5W energy-saving lamp consumes 1 kilowatt-hour in 200 hours. electricity. 2. Ultra-long lifespan: the semiconductor chip emits light, has no filament, no glass bubble, is not afraid of vibration, is not easy to break, and has a service life of up to 50,000 hours (the service life of ordinary incandescent lamps is only 1,000 hours, and the service life of ordinary energy-saving lamps is only eight thousand hours). 3. Health: Healthy light contains less ultraviolet and infrared rays, and produces less radiation (ordinary light contains ultraviolet and infrared rays). 4. Green and environmental protection: it does not contain harmful elements such as mercury and xenon, which is conducive to recycling. Ordinary lamps contain elements such as mercury and lead. 5. Eyesight protection: DC drive, no flickering (ordinary lights are AC driven, so flickering is inevitable). 6. High luminous efficiency: the highest luminous efficiency of CREE's laboratory has reached 260lm/W, and a single high-power LED on the market has also exceeded 100lm/W.
