Abstract

The utility model relates to an LED bulb lamp which comprises a lamp cover, a lamp jacket, a lamp holder, an LED lamp bead and a built-in drive power supply, wherein the lamp cover is a plastic lamp cover with high light transmittance and bulb lamp modeling, the lamp cover and a heat radiator are fixed on the lamp jacket through a fixing ring, the heat radiator is tightly connected with an aluminum substrate, a lamp shoulder is fixed on the lamp jacket and is in contact with the heat radiator, the lamp holder is rotatably connected to the lamp shoulder, and the built-in drive power supply is arranged in the lamp shoulder. The LED bulb lamp has the beneficial effects that a high light efficiency LED is adopted as an LED candle lamp light source, the contact area between the light source and a heat absorbing base of the heat radiator, working heat of the light source is favorably conducted to the heat radiator rapidly, so that the LED candle lamp for decoration and illumination is longer in service life; and the LED bulb lamp has the advantages of being high in light efficiency and simple in process, effectively reducing junction temperature, increasing light efficiency, reducing light attenuation, stabilizing color temperature and color rendering, and ensuring quality because a reasonable heat radiating structure and a special appearance design and a matched power supply are provided.

Description

The LED bulb lamp

Technical field

The utility model belongs to electronic information technical field, relates in particular to a kind of LED bulb lamp.

Background technology

The LED bulb lamp is the Novel energy-saving lamp that substitutes the conventional incandescent bulb.Conventional incandescent (tengsten lamp) power consumption is high, the life-span is short; under the overall situation of global resources anxiety; gradually, forbidden producing by national governments; substitute products are electronic energy-saving lamps thereupon; although electronic energy-saving lamp has improved energy-saving effect; but owing to having used the heavy metal element of many contaminated environment, run counter to again the main trend of environmental protection.Become gradually the only choosing of novel green illumination along with the high speed development LED illumination of LED technology.LED is far superior to the traditional lighting product on the aspect of principle of luminosity, energy-saving and environmental protection.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provides a kind of life-span long, built-in good heat dissipation, and technique is simple, the LED bulb lamp of high light efficiency.

The purpose of this utility model is finished by following technical solution, it comprises lampshade, lamp cover, lamp shoulder, lamp holder, LED lamp pearl, radiator, built-in driving power, described lampshade is the plastic lamp shade of high transmission rate, bulb lamp moulding, and be fixed in lamp with radiator by retainer plate and put this radiator) closely link to each other with aluminium base; Described lamp shoulder is fixed in lamp and puts, and contacts with radiator, is connected with lamp holder on this lamp shoulder, is placed with built-in driving power in the lamp shoulder.

As preferably, described LED lamp pearl is affixed on the aluminium base, and this LED lamp pearl is toward the lampshade inwall.

As preferably, two both positive and negative polarity electrodes are arranged on the described aluminium base, be connected on the respective electrode of built-in driving power, two electrodes of built-in driving power are connected on the respective electrode of lamp holder.

The beneficial effects of the utility model are: adopt high light efficiency LED as the LED candle-lamp light source, this light source has not only increased and the contact area at the radiator heat absorption end, be conducive to light source works heat is transmitted on the radiator rapidly, make decorative lighting longer with the LED candle lamp life-span; This candle lamp is compared with similar products: not only light efficiency is high, technique is simple, and has effectively reduced junction temperature, has improved light efficiency, reduced light decay, stablize colour temperature, colour rendering, added rational radiator structure and unique configuration design and the power supply that is complementary, guaranteed product quality.

Label in the accompanying drawing is respectively: 1, lampshade; 2, lamp cover; 3, lamp shoulder; 4, lamp holder; 5, LED lamp pearl; 6, radiator; 7, built-in driving power; 8, retainer plate; 9, aluminium base.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done detailed introduction: as shown in drawings, the utility model comprises lampshade 1, lamp cover 2, lamp shoulder 3, lamp holder 4, LED lamp pearl 5, radiator 6, built-in driving power 7, described lampshade 1 is the plastic lamp shade of high transmission rate, bulb lamp moulding, and be fixed on the lamp cover 2 by retainer plate 8 with radiator 6, this radiator 6 closely links to each other with aluminium base 9; Described lamp shoulder 3 is fixed on the lamp cover 2, and contacts with radiator 6, is connected with lamp holder 4 on this lamp shoulder 3, is placed with built-in driving power 7 in the lamp shoulder 3.Described LED lamp pearl 5 is affixed on the aluminium base 9, and this LED lamp pearl 5 is toward lampshade 1 inwall.Two both positive and negative polarity electrodes are arranged on the described aluminium base 9, be connected on the respective electrode of built-in driving power 7, two electrodes of built-in driving power 7 are connected on the respective electrode of lamp holder 4.

This LED bulb lamp has reached advanced international level and has compared with the technical merit of the like products such as conventional incandescent:

1, this LED bulb lamp adopts the high light efficiency LED small-power as light source, compares the LED lamp with traditional lighting and not only has energy-conservationly, and heat is little, and the life-span is long, and is safe without mercury, the advantages such as environmental protection, and also its luminous uniformity and uniformity are fine, have improved the light efficiency of light fixture.

2, this LED bulb lamp adds unique configuration design theory, modern design, good looking appearance.

3, this LED bulb lamp, the lamp cover 2 that adopts the plastic shell mix with built-in radiator 6 and dispel the heat, and the built-in aluminium of radiator 6 employings is made, LED lamp pearl 5 directly is encapsulated on the aluminium base 9, radiator 6 again with aluminium base 9 close contacts, solved the difficult problem of heat radiation, also improved production technology.

4, this LED bulb lamp, add the built-in driving power 7 that designed, designed is complementary with it, built-in driving power 7 is loaded in the lamp shoulder 3, fully played the insulating effect with radiator 6, and away from light source, reduced the too high impact on the driving life-span of built-in temperature, and output D.C. regulated power supply, offer the 5 constant current work of LED lamp pearl, guarantee the energy-efficient effect of product.
