Abstract
The utility model relates to the field of light-emitting diodes (LEDs), in particular to a high-efficiency low-power LED lamp. The overall power of the high-efficiency low-power LED lamp is generally not over 15 watts. The high-efficiency low-power LED lamp is mainly composed of a light source chip assembly (1), a lamp shell (2) and a driving power supply (3). Compared with the prior art, the high-efficiency low-power LED lamp can be made into a ball bulb lamp, a ceiling lamp, a down lamp, a desk lamp, a daylight lamp, and even a yard lamp, thereby being wide in application range. The high-efficiency low-power LED lamp can save energy by 80% than a common energy-saving fluorescent light, and can save energy by 20% than a present LED lamp using a heat dissipation sheet. The effects have been proved by a sample lamp used for four years. If the high-efficiency low-power LED lamp is popularized, saved electric power every year is equal to electric power emitted by a plurality of Three Gorges hydroelectric power stations in a whole year. The amount of aluminum alloy heat dissipation materials is inestimable. The high-efficiency low-power LED lamp has the advantages of being small in size, light in weight, free of utilization of heat dissipation sheets, low in cost, energy saving, long in service life, free of radiation, green, and environment-friendly, and completely working in a direct current state.
Description
Technical field
The utility model relates to a kind of based on the LED field, particularly a kind of high efficiency low-power LED illuminating lamp.
Background technology

For achieving the above object, the technical solution adopted in the utility model is:
A kind of high efficiency low-power LED illuminating lamp is characterized in that, comprises the light source chip combination, lamp outer casing, driving power.
Described light source chip is used in combination adjacent two distance of low-power LED lamp pearl greater than the diameter of lamp pearl itself, adopts tandem to connect.
Described lamp outer casing all adopts high-temperature resistance plastice, is comprised of power supply contact portion and plastic casing.
Described driving power is comprised of current-limiting circuit, rectification and power factor circuit, voltage control circuit, constant-current control circuit.
Compared with prior art, the utility model can be made bulb lamp, lamp affixed to the ceiling, Down lamp, desk lamp, fluorescent lamp even garden lamp.Purposes is very extensive.Than common fluorescent energy-saving streetlamp energy-saving 80%; Than the LED light fixture that uses at present fin also energy-conservation 20%; Its model light fixture has proved above-mentioned effect through the use in 4 years.If this achievement is promoted, can save the electric energy that a plurality of the three gorges hydropower plant sends the whole year every year, the aluminium alloy heat sink material of saving also is immeasurable.It is little to the utlity model has volume, lightweight, does not use fin, and low cost is energy-conservation, the long-life, be fully operational in dc state, and there is not a bit radiation, the advantage of environmental protection.
Description of drawings
Fig. 1 is the utility model structure chart.
Fig. 2 is the utility model driving power circuit figure.
Wherein, the combination of 1-light source chip, 2-lamp outer casing, 3-driving power.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further.
Present embodiment is a kind of high efficiency low-power LED illuminating lamp for the LED field, comprises light source chip combination 1, lamp outer casing 2, driving power 3.
Described light source chip combination 1 uses adjacent two distance of low-power LED lamp pearl greater than the diameter of lamp pearl itself, adopts tandem to connect.Particularly the lamp pearl on the lamp pearl printed circuit board (PCB) must be adopted the low-power LED lamp pearls such as straw hat straight cutting lamp pearl or 3528,3014,5050 and 5730, and namely the power of each lamp pearl is less than or equal to 0.5W.The lamp pearl all adopts tandem to arrange.The distance of two adjacent lamps pearls of arranging is greater than the diameter of lamp pearl itself, so can save metal fin fully.
Described lamp outer casing 2 all adopts high-temperature resistance plastice, is comprised of power supply contact portion and housing.Bulb lamp and Down lamp are ball or cylindrical shape, so LED lamp pearl plate is circular slab, namely arrange the lamp pearl at circular slab; If the part of fluorescent lamp, square ceiling lamp or corn lamp, LED lamp pearl plate is elongated plates or square plate, namely arranges the lamp pearl in elongated plates or square plate; If the disc lamp affixed to the ceiling, LED lamp pearl plate is annular slab.Circle or annular diameter are from 20mm to 400mm; The square length of side is from 20mm to 300mm; The shortest in the rectangle is a section of corn lamp, only has 30mm, and the longest is fluorescent lamp, and length reaches 2000mm.
Described driving power 3 is comprised of current-limiting circuit, rectification and power factor circuit, voltage control circuit, constant-current control circuit.
1, current limliting or holding circuit: formed by fuse, resettable fuse or pressure cell;
2, rectification and power factor circuit: formed by commutation diode or rectifier bridge and passive power factor electronic component;
3, voltage control circuit: formed by passive device;
4, constant-current control circuit: formed by transistor and barretter.
Output termination load (LED lamp pearl).All the driver of element formation does not generate heat, reliable operation, and the life-span is extremely long, and is inexpensive, do not need integrated circuit, and complete cost is fit to large-scale popularization below two yuan.The volume of driver only has 30mm * 20mm * 20mm.Can be placed in the very little bulb lamp.This constant-current source driver of supplying with lamp pearl printed circuit board (PCB) has circuit simple (not using import or domestic integrated circuit), efficient height, has the function of the accurate constant current of high voltage.Itself does not generate heat yet, and makes its life-span can be more much longer than traditional on the market voltage-stabilized power supply, constant-current source and Switching Power Supply, can with long-life LED lamp pearl synchronised.
