Background technology
Global according to statistics lighting highway and tunnel illumination, the illumination of block, urban district, plaza lighting, fields such as golf course illumination, adopt the conventional high-tension sodium lamp lighting mostly, have more than 10,000 ten thousand, and increase progressively with 10% speed, the optical cavity sealing protection requires more than the IP65, silica gel sealing ring and silica gel belong to organic material together, qualitative change takes place under long-time high temperature and ultra-violet radiation state, the sealing ring lost of life, requirement of shelter is satisfied gradually decline, general good silica gel sealing ring begins after 3 years to change, after silica gel sealing ring is aging, exist aqueous vapor to immerse, dust and insect are immersed pollution glass and go out light shield, cause the actual light efficiency of light fixture to descend, at present, the actual light efficiency of new conventional road lamp also has only 40Lm/W, and the conventional lights solution is utilized from the breath method cooling, can only be explosion-proof, it is limited to lower the temperature, still can not satisfy silica gel material to temperature requirements, waste energy and manpower, increase maintenance cost simultaneously.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, and the street lamp in a kind of more energy-conservation, low-cost, safe and reliable prolongation optical cavity sealing ring life-span is provided.
The present invention solves the technical scheme that its technical problem adopts: the street lamp in this prolongation optical cavity sealing ring life-span, mainly comprise the light fixture upper casing, the light fixture lower casing, light source, printing opacity safety glass, reflector and silica gel sealing ring, light fixture upper casing and light fixture lower casing cooperatively interact, be provided with reflector in the light fixture upper casing, light source places in the reflector, light source is fixing by the lamp cover, the light-emitting window place of light fixture lower casing is provided with printing opacity safety glass, printing opacity safety glass contacts with reflector, the contact position of printing opacity safety glass and reflector is provided with silica gel sealing ring, be connected and fixed by fastener between light fixture lower casing and the reflector, the rear portion and the lamp stand of light fixture upper casing and light fixture lower casing are connected and fixed.
Be provided with respirator and power supply in the described lamp cover.
The inside of described light fixture upper casing and light fixture lower casing scribbles heat-absorbing paint.
Described fastener is clam member or fastening trim ring.
Described fastener is an aluminium matter or copper.
The effect that the present invention is useful is: the present invention is via the enforcement of lower casing inner-wall spraying heat-absorbing material on aluminium matter pressing plate or copper fastener and the light fixture, played the effect of good heat radiation and cooling, solved conventional road lamp optical cavity problem sealing life, simultaneously can dwindle the conventional road lamp volume, total quality, reduce light fixture comprehensive cost and cost, increase light fixture service life and stability, the long light fixture maintenance period in the court of a feudal ruler.

The specific embodiment
The invention will be further described below in conjunction with drawings and Examples:
As shown in the figure, the street lamp in this prolongation optical cavity sealing ring life-span, mainly comprise light fixture upper casing 2, light fixture lower casing 4, light source 8, printing opacity safety glass 5, reflector 1 and silica gel sealing ring 6, light fixture upper casing 2, light fixture lower casing 4 and reflector 1 are aluminum material, light fixture upper casing 2 and light fixture lower casing 4 cooperatively interact, the inwall of light fixture upper casing 2 and light fixture lower casing 4 scribbles heat-absorbing paint, and heat-absorbing paint has aberration.Be provided with reflector 1 in the light fixture upper casing 2, light source 8 places in the reflector 1, and light source 8 is fixing by lamp cover 3, is provided with respirator 1 and electrical equipment 11 in the lamp cover 3, and respirator 9 plays the effect of air-flow exchange, and light source 8 is luminous by electrical equipment 11.The light-emitting window place of light fixture lower casing 4 is provided with printing opacity safety glass 5, printing opacity safety glass 5 contacts with reflector 1, printing opacity safety glass 5 is provided with silica gel sealing ring 6 with the contact position of reflector 1, be connected and fixed by fastener 10 between light fixture lower casing 4 and the reflector 1, form the optical cavity of a sealing, fastener 10 is aluminium matter or copper clam member 12 or fastening trim ring 13, quickens optical cavity generation heat after lighting and is delivered to light fixture upper casing 2.The rear portion of light fixture upper casing 2 and light fixture lower casing 4 and lamp stand 7 are connected and fixed.
Utilize reflector 1 aluminum material and lamp outer casing aluminum material characteristic, by heat sink, heat conduction and radiation, radiating principle, light fixture is lighted according to the heat sink principle of falling heat in the reflector optical cavity of back is delivered to light fixture upper casing 2 after by aluminium or copper clam member 12 or 13 heat build-ups of fastening trim ring and light fixture lower casing 4 quickens natural heat dissipations, utilize light fixture internal layer heat-absorbing paint to form aberration and absorb heat, realize reducing heat in the optical cavity by the heat radiation of reflector optical cavity, satisfy organic material silica gel to temperature requirements, the long silica gel sealing ring life-span of the court of a feudal ruler, improve optical cavity and light fixture upper casing Contact Seal ring service life, make full use of the heat radiation of conventional lamp (die casting aluminium) shell, reduce maintenance cost.
