Abstract

The utility model relates to a light emitting diode (LED) lamp, which comprises a lamp base, a convex lens and a column-shaped lamp shade; a plurality of LEDs are arranged on an arc-shaped lamp holder on the lamp base and positioned below the convex lens; a sunken conic opening can be formed at the bottom of the convex lens; a layer of reflectance coating is applied on the inner edge of the conic opening; the heads of the plurality of LEDs all point to the peak of the conic opening; and a layer of nanophosphor powder is applied on the outer surface of the each LED. In the utility model, the convex lens is adopted, the sunken conic opening can be formed at the bottom of the convex lens, and a layer of reflectance coating is applied on the inner edge of the conic opening, so that light rays projected by the plurality of LEDs can pass the reflectance coating directly and are refracted by the convex lens to form light-focusing effect, further, special lighting needs can be satisfied.

Description

A kind of led lamp

Technical field

The utility model relates to a kind of led lamp.

Background technology

LED is directly had the following advantages as lighting: 1, the LED consumed energy reduces 80% with the incandescent lamp of light efficiency; 2, LED does not have poisonous metal mercury, can not pollute environment; 3, LED uses low-tension supply, and supply voltage is between 6-24V, and is different and different according to product, so it is a safer power supply of ratio use high voltage source, is specially adapted to public place and family and uses.

Though the LED light fixture has numerous advantages, outside himself astigmatic effective, spotlight effect is relatively poor, can not meet the special lighting requirement.

In addition, LED directly can produce a large amount of heats as illuminating lamp, if the heat that LED gives out can not in time shed, will have influence on the service life of LED light fixture and the brightness that can have influence on the LED light fixture.

Moreover the lamp socket reflection ray usefulness of existing LED light fixture is relatively poor, can absorb a large amount of luminous energy, thereby can have influence on illuminating effect.

Summary of the invention

The utility model has designed a kind of led lamp, and the technical problem of its solution is:

(1) existing LED light fixture spotlight effect is bad, can not meet the special lighting requirement;

Be easy to generate a large amount of heats when (2) traditional LED light fixture uses, be difficult for shedding and can have influence on the service life and the brightness of LED light fixture.

In order to solve the technical problem of above-mentioned existence, the utility model has adopted following scheme:

A kind of led lamp comprises light fitting base, convex lens sheet and cylindricality lampshade, is provided with a plurality of light emitting diodes on the arc lamp socket on the described light fitting base, and described a plurality of light emitting diodes are positioned at the below of described convex lens sheet; The cone ports of caving in can be formed on described convex lens sheet bottom, and is coated with one deck reflectance coating at the inner edge of described cone ports, and the head of described a plurality of light emitting diodes all points to the summit of described cone ports; The outer surface of described light emitting diode applies a nano fluorescent bisque.

Further, described light fitting base and cylindricality lampshade interconnect by screw thread.

Further, described convex lens sheet sticks on the described cylindricality lampshade by colloid.

Further, the bottom of described light fitting base is provided with a plurality of louvres.

Further, be provided with radiating fin bottom the described light fitting base.

This led lamp is compared with traditional led lamp, has following beneficial effect:

(1) the utility model is owing to be provided with convex lens sheet, and the cone ports of caving in can be formed on the convex lens sheet bottom, and be coated with one deck reflectance coating at the inner edge of cone ports, therefore can allow the light that a plurality of light emitting diode throwed, directly light refraction is come out by reflectance coating and by convex lens sheet, form the effect of optically focused, to satisfy special lighting demand.

(2) the utility model is owing to apply one deck nano fluorescent bisque at a plurality of light-emitting diodes tube outer surfaces, and the light that this nano fluorescent bisque can make light emitting diode send is softer or strong, can reduce the quantity that LED uses, and saves manufacturing cost.

(3) the utility model is owing to be provided with a plurality of louvres and radiating fin in the bottom of light fitting base, and a large amount of heats that this louvre and radiating fin can send light emitting diode are in time derived, and have prolonged the service life of led lamp.

The specific embodiment

Below in conjunction with Fig. 1 to Fig. 3, the utility model is described further:

As shown in Figure 1, a kind of led lamp comprises light fitting base 10, convex lens sheet 20, a plurality of light emitting diode 11 and cylindricality lampshade 30.Be provided with a plurality of light emitting diodes 11 on the arc lamp socket 13 on the described light fitting base 10, described a plurality of light emitting diodes 11 are positioned at the below of described convex lens sheet 20.The cone ports 21 of caving in can be formed on described convex lens sheet 20 bottoms, and is coated with one deck reflectance coating 22 at the inner edge of described cone ports 21, and the head of described a plurality of light emitting diodes 11 all points to the summit of described cone ports 21; Described light fitting base 10 and cylindricality lampshade 30 interconnect by screw thread 12.Described convex lens sheet 20 sticks on the described cylindricality lampshade 30 by colloid.

The bottom of described light fitting base 10 is provided with a plurality of louvres 14 and radiating fin 40.A large amount of heats that this louvre 14 and radiating fin 40 can send light emitting diode 11 are in time derived, and have prolonged the service life of led lamp.

As shown in Figure 2, described a plurality of light emitting diode 11 reflexes on the described reflectance coating 22.The light that therefore can allow a plurality of light emitting diodes 11 be throwed directly comes out light refraction by reflectance coating 22 and by convex lens sheet 20, forms the effect of optically focused, to satisfy special lighting demand.

As shown in Figure 3, the outer surface of described light emitting diode 11 applies a nano fluorescent bisque 111.This nano fluorescent bisque 111 can reduce the quantity that high-capacity LED uses so that the light that light emitting diode 11 sends is softer or strong, saves manufacturing cost.

In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obvious realization of the present utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or design of the present utility model and technical scheme are directly applied to other occasion without improving, all in protection domain of the present utility model.
