A kind of LED bulb lamp

Technical field

The utility model relates to a kind of light fixture, particularly relates to a kind of LED bulb lamp.

Background technology

According to one's analysis; The annual electric energy in the whole world has 15%～30% to consume on lighting apparatus; Improving the electric energy comprehensive utilization ratio of illuminator and carrying out power saving operation has great economic implications, under the background of 21 century energy scarcity, promotes the significant of energy-saving illumination product.The LED lamp is energy-conservation illuminating product by countries in the world analogies in recent years always, compares with incandescent lamp and fluorescent lamp, and LED lamp power consumption is little, can low-voltage, the low current starting, and long service life, the working time can reach more than 30,000 hours; LED lamp reaction speed is fast, but high-frequency operation, and environmental protection, shatter-proof, shock-resistant difficult broken, recyclable as discarded object, do not pollute.A good LED illuminating product must have high LED constant-current drive circuit and good radiator structure, a suitable diffuser and an anti-dazzle of reliability to handle.

The shell mechanism moulding of existing LED bulb lamp light fixture is single, and radiating effect is very poor, and the life-span is shorter; And if the diffuser of LED bulb lamp selects for use ground unreasonable, also can be with dazzling light, dazzle light and can cause human visual tired and influence the human eye perception of light intensity to external world.Though with respect to traditional lighting; Led light source has irreplaceable advantage; But in practical application, how to remove to avoid to dazzle the problem of light and the luminous flux of the least possible loss light source, improve the radiating effect of whole lamp, strengthening whole lamp service life is the technical problem that present urgent need will solve.

The utility model content

The utility model first technical problem to be solved is the LED bulb lamp that a kind of perfect heat-dissipating is provided to above-mentioned prior art.

The utility model second technical problem to be solved is to be directed against the LED bulb lamp that above-mentioned prior art provides a kind of not only good heat dissipation effect, can also effectively avoid dazzling optical issue.

The utility model solves the technological means that above-mentioned first technical problem adopted: this LED bulb lamp; Comprise globe holder; Be provided with led light source in the globe holder; It is characterized in that: said led light source is fixed on the heat-conducting substrate, and this heat-conducting substrate then is arranged on the heat conduction Section Bar Heat Sinks that is connected with globe holder, and the outer wall of this heat conduction Section Bar Heat Sinks is provided with the fin that longitudinal divergence distributes.

Preferably; Above-mentioned heat conduction Section Bar Heat Sinks is the aluminium section bar radiator, and this aluminium section bar radiator adopts aluminum alloy materials, processes integral piece by anode oxidation process; Like this; The heat that the aluminium section bar radiator is produced when can be with led light source luminous dissipates to the external world with the mode of free convection and conduction from bottom to top by air and is dissipated in the ambient air, with eliminate because of overheatedly cause the luminous power of led light source to descend, the colour temperature drift, and then influence the brightness of illumination and the problem in led light source life-span.

As improvement; Heat conduction Section Bar Heat Sinks below is provided with a lamp holder connector in the LED bulb lamp that the utility model provides, and this lamp holder connector adopts PBT material wear-resisting, that heat distortion temperature is higher and flame retardant rating is higher to process, and around the lamp holder connector, has designed a lot of the louvres that open wide uniformly; The heat of deriving by the heat conduction Section Bar Heat Sinks like this; Can be derived by the louvre above the lamp holder connector with the mode of convection current, through the air exchange of these louvres and outside, cooling-down effect is very good; Long service life; Good looking appearance obviously improves the configuration design space and the external aesthetic property of LED bulb lamp, and consumer's acceptance level also can improve like this.The baking vanish processes has been adopted in lamp holder connector outside, and baking vanish technology has tangible reinforcement work to heat radiation, and therefore, thereby it has solved the not good short problem in service life that causes of existing LED light fixture radiating effect.

The utility model solves above-mentioned second technical scheme that technical problem adopted: on the basis of above-mentioned LED bulb lamp structure, said globe holder is an optical grade PMMA diffuser.Diffuser is preferably milky, and this globe holder links to each other with said lamp holder connector through playing glue.The milky white diffuser of the optical grade PMMA that selects for use has added anti-UV, and is anti-oxidant; The anti-aging material that waits, high temperature resistant, light transmittance is up to more than 92%; Inner surface adopts frosting, and the effective like this LED that prevented dazzles the uncomfortable degree that light causes human eye, and light loss is little; Illumination is even, and visual effect is very good.

And said led light source adopts LED COB planar light source, and this planar light source luminous flux and colour rendering index are all high a lot of than general led light source, and color reducibility is better.

Improve, said heat-conducting substrate adopts aluminium base again, and aluminium base then adopts the higher aluminium of thermal conductivity factor to process, and radiating effect is fabulous, and insulating properties and mechanical performance are also very good.The aluminium base surface design four screw holes, can this aluminium base and aluminium section bar radiator and lamp holder connector be fixed with tapping screw, adopt screw to connect; Be prone to assembling; Compare fixed form in the past, the lock screw has been simplified fit, has accelerated assembling speed; Improved production efficiency, the firm firm while that lets whole modulated structure become has also been improved safety coefficient accordingly.

Improve, said lamp holder connector below is provided with lamp holder again, and this lamp holder adopts screw socket; And be made up of threaded body, insulating part, metal buckle closure, cap screw thread main body and insulating part are fixed as one, and endoporus, power supply lead wire groove are arranged on the insulating part; After power line passed from endoporus, lateral bending was placed in the power supply lead wire groove, establishes the metal buckle closure on the insulating part; The two flexibly connects, and integral body and power line that the metal buckle closure is formed through interference fit and insulating part and cap screw thread main body are fixed together, and become an electrode; Realize being connected of lamp holder and power line, changed common welding lamp holder and welded the fixed power source Wiring technology, eliminated and welded the harm that environment and human body are caused and saved the energy with high temperature scolding tin; Its assembly technology is simple, and packaged convenience is specious.

Compared with prior art, the advantage of the utility model is:

1, the heat conduction Section Bar Heat Sinks of the utility model is provided with fin, surperficial anodized, good heat dispersion performance;

2, the utility model is a kind of energy-efficient product, and is environment friendly and pollution-free, meets international standard;

3, the utility model exquisite appearance, light weight, cost is low;

4, the lamp holder plastic fastening surface of the utility model is provided with many louvres, and it is with the obvious advantage to dispel the heat;

5, the diffuser of the utility model has effectively prevented to dazzle the uncomfortable degree that light causes human eye;
