Description

A kind of LED hangs down the canopy lamp

Technical field

The utility model relates to a kind of light fixture, specifically provides a kind of LED to hang down the canopy lamp.

Background technology

Under the background that the worry of global energy shortage raises once again, energy savings is the important problem that we shall face future, at lighting field, the application of LED luminous product is just attracting common people's sight, the LED light fixture is as a kind of novel green light source product, must be developing tendency in future, it be the novel illumination light source epoch of representative that 21st century will enter with LED.Compare with incandescent lamp and fluorescent lamp, the LED light fixture has the advantage that volume is little, the life-span is long, light efficiency is high, and can many multiple combinations, LED lamp caloric value is low, does not have heat radiation basically, and LED lamp power consumption is little, can low-voltage, the low current starting, long service life, the working time can reach more than 10,000 hours, and 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 a LED constant-current drive circuit that reliability is high, good radiator structure, and suitable diffuser and anti-dazzle are handled.

Existing LED is low, and canopy lamp lamp outer casing Mechanical Builds is single, and radiating effect is very poor; And if the diffuser that the low canopy lamp of LED is selected for use is improper,, dazzles light and can cause human visual fatigue and influence the human eye perception of light intensity to external world also with dazzling light.Though with respect to traditional lighting, led light source has irreplaceable advantage, but how to remove to avoid to dazzle the problem of light and the luminous flux of the least possible loss light source in actual applications, improve the radiating effect of whole lamp, strengthening whole lamp service life is the present anxious technical issues that need to address.

The utility model content

Technical problem to be solved in the utility model is the low canopy lamp of LED that a kind of perfect heat-dissipating is provided at above-mentioned prior art.

The utility model solves the problems of the technologies described above the technological means that is adopted: this LED hangs down the canopy lamp, comprise and be located at the outer housing of led light source, it is characterized in that: described housing comprises aluminium alloy inner casing and aluminum alloy casing two parts, aluminum alloy casing is wrapped in outside the aluminium alloy inner casing, aluminium alloy inner casing and aluminum alloy casing all are sprayed with fine sand layer outward, and be provided with locating hole on aluminium alloy inner casing and the aluminum alloy casing, be provided with aluminium base in the aluminium alloy inner casing, described aluminium base top is provided with LED COB planar light source.Housing is by the aluminium alloy inner casing and aluminum alloy casing is overlapping forms, the heat that housing is produced when can be with led light source luminous dissipates to the external world in the mode of free convection and conduction from bottom to top by air and is dissipated in the ambient air, to eliminate the luminous power decline that causes the led light source source because of overheated, colour temperature is elegant, and then influencing the problem of brightness of illumination, radiating effect significantly improves simultaneously.Inner and outer shell surface spray fine sand, abrasive jet cleaning can make the radiating shell surface expose the metal true qualities of uniformity, makes the heat-dissipating casing surface more attractive in appearance, reaches the effect of beautifying and decorating, has increased heat emissivity coefficient simultaneously.Like this, housing has the mechanical performance of superelevation and good thermal conductivity factor, heat conduction, heat radiation, convection current is with the obvious advantage, radiating effect persistent high efficiency, long service life, good looking appearance obviously improves the configuration design space and the external aesthetic property of LED light fixture, consumer's acceptable degree height.Its application flexibility makes it can be used for nearly all shape and size product, and not multiple performances such as viscosity, hear resistance, sliding, moisture resistance, mar proof, corrosion resistance are arranged.Thereby it has solved the not good short problem in service life that causes of existing LED light fixture radiating effect.

As improvement, described LED COB planar light source is outside equipped with a macromolecule PC diffuser, and diffuser links to each other with aluminium base by tapping screw, select LED COB planar light source for use, this planar light source luminous flux and colour rendering index are all high a lot of than general led light source, color reducibility is better, outside LED COB planar light source, be covered with a macromolecule PC diffuser, light transmittance is up to more than 92%, prevented that effectively LED from dazzling the uncomfortable degree that light causes human eye, and light loss is little, and illumination is even, and visual effect is very good.

Improve again, be connected with the lamp holder plastic fastening on the described aluminum alloy casing, this lamp holder plastic fastening surface is provided with a plurality of louvres, can good exchange be arranged with outside air, thermal convection current is with the obvious advantage, and material can adopt wear-resisting, and the PBT that heat distortion temperature is higher and flame retardant rating is higher makes, the processing of can spraying paint on the surface, this can play positive role to heat radiation and convection current.

Preferably, adopt screw fixation method to be connected between lamp holder connector and the described radiating shell.Adopt the screw mode to connect, easily assembling, the glue of comparing in the past of beating is fixed, and the lock screw has been simplified the assembling mode, has accelerated assembling speed, has improved production efficiency, and the firm firm while that allows structure become has also been improved safety coefficient accordingly.

Improve again, described lamp holder connector below is provided with lamp holder, this lamp holder adopts screw socket, and by threaded body, insulating part, the metal buckle closure is formed, cap screw thread main body and insulating part are fixed as one, endoporus is arranged on the insulating part, the power supply lead wire groove, after power line passes from endoporus, lateral bending is placed in the power supply lead wire groove, establishes the metal buckle closure on the insulating part, the two flexible connection, integral body and power line that the metal buckle closure is formed by interference fit and insulating part and cap screw thread main body are fixed together, become an electrode, the realization lamp holder is connected with power line, has changed common welding lamp holder and has welded the fixed power source Wiring technology with high temperature scolding tin, eliminate the harm that welding causes environment and human body and saved the energy, its assembly technology is simple, and packaged convenience is specious.

A kind of LED that the utility model provides hangs down the canopy lamp, lamp holder nickel plating brightness height, the rust-proofing ability is strong, and lamp holder is that injection moulding is finished, and replaces the glass insulator of glass lamp holder with plastics, with traditional scolding tin lamp holder ratio environmental protection is arranged, easily line ball is in light weight, contact stabilization, advantages such as low price have progressively replaced old-fashioned scolding tin lamp holder.Plastic head is the material of fire-retardant anti-high temperature, and green is arranged, white, various color matchings such as black.The lamp holder material has iron and aluminium matter, and wherein aluminium nickel plating and aluminium alloy lamp holder have the characteristics of Never-rusty.

Compared with prior art, advantage of the present utility model is: housing aluminium alloy material is made shell and inner casing, and surface sand-blasting is handled, good heat dispersion performance.
