Abstract

The utility model relates to a novel LED (light-emitting diode) energy-saving lamp which comprises a lamp cap, a driver and a radiator. A metal substrate is fixed on the radiator. An LED light emitting chip is welded on the metal substrate. The LED light emitting chip is provided with an adhesive layer doped with LED fluorescent powder. The LED light emitting chip is connected with the lamp cap and the driver through power wires. A glass cover is arranged below the LED light emitting chip. The novel LED energy-saving lamp has the beneficial effects that 1, the novel LED energy-saving lamp has a simple structure, is easy to assemble and has good heat transfer and dissipation performance effect; 2, compared with a conventional metal radiating fin, the ceramic radiator adopted in the novel LED energy-saving lamp has lower cost and good radiating effect; and 3, due to the adoption of one complete LED, the novel LED energy-saving lamp is beneficial for coating the LED fluorescent powder, the generated light is more centralized, and the light with diffuse reflection effect, which is generated by the glass cover, is more uniform and mild.

Description

A kind of new LED electricity-saving lamp

Technical field

The utility model relates to LED electricity-saving lamp field, especially a kind of new LED electricity-saving lamp.

Background technology

Existing LED electricity-saving lamp is welded on the resin PCB circuit board for the plurality of LEDs light emitting diode; Circuit board is fixed on the metal fin through screw; Its shortcoming is: one, the heat that produces of LED sees through circuit board and passes to that the metal fin radiating effect is undesirable behind, and more complicated is installed; Two, the manufacturing radiating fins cost is higher; Three, light source is made up of a plurality of single LEDs, and is luminous even inadequately.

Summary of the invention

The utility model will solve the shortcoming of above-mentioned prior art, provides a kind of heat radiation, illumination effect good, lower-cost new LED electricity-saving lamp.

The utility model solves the technical scheme that its technical problem adopts: this new LED electricity-saving lamp; Comprise lamp holder and driver, radiator; Be fixed with metal substrate on the radiator, be welded with the LED luminescence chip on the metal substrate, the LED luminescence chip is provided with the glue-line that is mixed with LED fluorescent material; The LED luminescence chip is connected with lamp holder and driver through power line, and LED luminescence chip below is provided with cloche.

As preferably, said LED luminescence chip can be a monoblock rectangle or a circular configuration.

As preferably, said metal substrate is fixed on the radiator through being threaded.

As preferably, said radiator adopts ceramic material.

As preferably, said power line go out the periphery that line position is the LED luminescence chip.

As preferably, the thickness of said metal substrate is 2-6mm.

The effect that utility model is useful is: one, simple in structure, assembling is easy, and the heat transfer heat dispersion is effective; Two, the metal fin cost that adopts ceramic heat sink to compare traditional is lower, good heat dissipation effect; Three, owing to adopt the LED of a monoblock to help the LED fluorescent powder coating, the light of generation is more concentrated, and the diffuse effect light that produces through cloche is more evenly soft.

Fig. 2 is the structural representation of metal substrate;

Description of reference numerals: metal substrate 1, radiator 2, LED luminescence chip 3, the glue-line 4 that is mixed with LED fluorescent material, power line 5, cloche 6, lamp holder and driver 7.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further:

Embodiment: like Fig. 1,2, this new LED electricity-saving lamp comprises lamp holder and driver 7 and radiator 2, and radiator 2 adopts ceramic material, more practices thrift cost with respect to metal material, and has insulating properties.Radiator 2 is fixed with metal substrate 1 through being threaded, make things convenient for installing/dismounting, and metal substrate 1 material is aluminum or aluminum alloy (presses down and perhaps be copper or copper alloy), is shaped as flat cylinder, and through punch forming, thickness is at 2-6mm.Metal substrate 1 is welded as a whole with LED luminescence chip 3, makes that the heat transfer radiating rate is faster, and a plurality of LED luminescence chips 3 cover the glue-line 4 that is mixed with LED fluorescent material through the upper strata and are encapsulated as together, can rectangular, circular or other shapes.LED luminescence chip 3 is connected with lamp holder and driver 7 through power line 5, power line 5 go out the periphery of line position at LED luminescence chip 3.LED luminescence chip 3 belows are provided with cloche 6, and the light that the integral LED light source produces is more concentrated, and the diffuse effect that produces through cloche 6 makes light more evenly soft.

Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
