Abstract

The utility model discloses an LED (Light Emitting Diode) lamp with ultralow attenuation and ultrahigh efficiency. In a lamp shade, an LED chip is directly welded on a circuit board provided with a via hole, a power line is connected with a circuit by the via hole of the circuit board, the other surface of the circuit board is connected with a high heat conduction board, the circuit board is provided with an electric signal element, the circuit board is made of copper-clad plate material and is fastened and connected with the high heat conduction board through high-temperature soldering by solder paste, the high heat conduction board is made of high heat conduction material, and a via hole of the high conduction board is matched with the via hole of the circuit board. The attenuation of the LED chip is mainly caused by the high temperature degeneration of rubber mass, and as no rubber mass is adhered on the surface of the LED chip, the attenuation caused by the degeneration of the rubber mass can be avoided. For the LED lamp, the structure is compact, the design is reasonable, the manufacturing is simple, and the convenience, safety and durability are realized.

Description

A kind of ultralow attenuation high-efficiency LED light fixture
Technical field
The utility model relates to a kind of LED light fixture, relates in particular to a kind of ultralow attenuation high-efficiency LED light fixture.
Background technology
Semiconductor light-emitting-diode (being called for short LED) is that a kind of energy-saving and environmental protection, color are pure, the solid light source of overlong service life; scientific circles, engineering bound pair LED Study on Technology are very active always in recent ten years, and light sources such as the incandescent lamp that uses led light source to replace generally to use at present, fluorescent lamp, electricity-saving lamp are started to walk.Each country of the world and company all drop into the luminous efficiency that great amount of manpower and material resources research improves semiconductor light-emitting-diode, development of new chip design technology, packaging technology material technology, source material technology, light fixture material technology etc.Because light emitting diode itself is very sensitive to heat, himself temperature is created a great impression to luminous efficiency, life-span, encapsulating material sex change.The heat dispersion of light emitting diode has very important influence to luminous efficiency, bad if dispel the heat, can cause the temperature of pn knot too high, cause luminous efficiency to descend, LED self life-span reduces, the material that surrounds led chip is formed fire damage, and this will make the LED luminous efficiency significantly reduce again, and it is the key in LED luminous efficiency and life-span that the led chip heat in time sheds.Because all on illuminator or electronic controller power device, the heat of conventional light source light fixture can not be directly transferred on the lamp outer casing conventional light source heat.
The utility model content
The utility model will address the above problem and be to provide a kind of ultralow attenuation high-efficiency LED light fixture that fast the led light source heat is directly transferred to shell by high heat-conducting plate.
For addressing the above problem, the utility model is realized by following scheme: a kind of ultralow attenuation high-efficiency LED light fixture, and in lampshade, led chip directly is welded on the circuit board of via hole, power line is by the via hole connecting circuit of circuit board, and the circuit board another side connects high heat-conducting plate.
Described led chip encapsulates without colloid, the led chip decay mainly is because the high-temperature denatured decay that causes of colloid, chip itself is also unattenuated, with this technology can be that the luminous quantity of chip is bigger, owing to there is not colloid to be attached to the surface, the decay of avoiding the colloid sex change to cause, being welded on LED blue chip on the circuit board heat that dispels the heat is directly transferred on the compound circuit plate of high heat-conducting, lead on the metal shell by the compound circuit plate again, and the shell fin of metal material can module superpose, the heat that the LED blue chip is produced that can be quantitative is transmitted on the shell of light fixture timely, thus the luminous efficiency and the service life of improving led light source significantly.Evenly coat bloom on transparent cover, the transparent cover that scribbles bloom is buckled on the circuit board of encapsulation, and the blue light of sending with LED forms white light, reaches the effect of lighting source.
The ultralow attenuation high-efficiency LED of the utility model light fixture has solved the directly quick conductive can of led light source heat and has been dispersed in the air, improve source efficiency, and the decay of having avoided led chip to be produced in the colloid sex change, form ultralow attenuation high-efficiency LED light fixture, and structure is fastening, reasonable in design, make easily, convenient and safe and durable.
Description of drawings
Fig. 1 is a structure cutaway view of the present utility model;
Fig. 2 is a circuit board vertical view of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of ultralow attenuation high-efficiency LED light fixture, in lampshade 4, led chip 2 directly is welded on the circuit board 1 of via hole 5, and power line is by via hole 5 connecting circuits of circuit board 1, and circuit board 1 another side connects high heat-conducting plate 3.
As shown in Figure 2, circuit board 1 is equipped with signal of telecommunication device, and circuit board is the copper-clad plate material.Soldering is fastenedly connected circuit board 1 through high temperature with high heat-conducting plate 3 usefulness tin creams.High heat-conducting plate 3 is highly heat-conductive materials, and described high heat-conducting plate 3 via holes 5 match with circuit board 1 via hole 5.The conducting shell that circuit board 1 provides power supply lead wire, the heavy copper of via hole, scolding tin process hole to form high heat conduction for led chip 2, the heat that high heat-conducting plate 3 sheds by via hole welding conduction led chip 2.
