Description

Energy-saving and long-life LED lights

Technical field:

The utility model relates to the technical field of light-emitting diodes (LEDs), in particular to an energy-saving and long-life LED lamp.

Background technique:

Light-emitting diode (LED) is a semiconductor solid light-emitting device. It uses a solid semiconductor wafer as a light-emitting material. When a forward voltage is applied to both ends, the carriers in the semiconductor recombine to cause photon emission to generate light. It is the most The popular light source technology, the characteristics of LED light source are: energy saving: energy consumption is reduced by 80% compared with incandescent lamps with the same light effect; using low voltage power supply (between 6-24V), good safety; small size, can be prepared into various Shaped devices; long life; fast response time: the response time of incandescent lamps is milliseconds, and the response time of LED lamps is nanoseconds; no harmful metal mercury pollution to the environment, etc., with the development and application of high-power LED lamps, LED lights have developed from point light sources to functional lighting, and the development prospects are extremely broad.

However, it has been found from application and practice that the LED lamps produced at home and abroad, especially the white LED lamps, have obvious shortcomings: one side of the LED chip emits light outwards, and the other side leans against the bowl and does not emit light. The non-luminous side can only be transmitted through the bowl and cup in the form of heat. One is to cause an increase in heat, the other is to cause a waste of energy or a decrease in luminous flux (only the light emitted by one side is used), and the third is to make the white light diode. Poor color temperature stability and low product life.

In this case, Chinese patent applications No. 200710030060.8 and No. 200720056529.0 have proposed a technical solution of "light-emitting diode with bidirectional light emission and heat dissipation", which is to lead out the positive and negative electrodes on the light-emitting diode chip with lead wires and extend them to the lens The pins outside the cover are connected, the lens cover can cover the chip, at least one chip is fixed in the through hole on the substrate, and a light-transmitting and heat-insulating medium can also be set between the outer surface of the chip and the lens cover. A layer of fluorescent powder is arranged on the outer surface of the medium or on the lens cover, so that the LED chip can emit light on both sides of the through hole on the substrate. In the case of the same power consumption, not only the brightness of the LED lamp is increased, but the The improvement of luminous efficiency also solves the problem of poor heat dissipation of single-sided LED lamps. Because the white-emitting LED lamp isolates the phosphor powder from the chip, the phosphor powder is not suitable for heating and aging and carbonization and blackening, so that the life of the LED lamp is improved. However, because the connection structure between the technical solution and the lamp body has not been solved, the products containing this technology have not been introduced to the market so far.
