Abstract
The utility model relates to a lamp cap of an LED (Light Emitting Diode) streetlamp, which comprises a lamp housing, at least one LED module and a power module, wherein the LED modules and the power module are arranged inside the lamp housing, the lamp housing comprises an upper lamp housing and a lower lamp housing, a plurality of heat dissipating holes are formed in the upper lamp housing, and a plurality of water outflow holes are formed in the lower lamp housing; clearances are formed between each two of the lower lamp housing, the LED module and the power module, a heat dissipating channel is formed by the clearances between each two of the lower lamp housing, the LED module and the power module, and another heat dissipating channel is formed by the heat dissipating hole and the water outflow hole. According to the lamp cap of the LED streetlamp provided by the utility model, problems of hindered ventilation caused by the sealing of the LED lamp heat sink in the lamp housing, and the low natural convection heat dissipating coefficient are overcame, so as to improve the heat dissipating effect of the LED lamp and prolong the service life of the LED lamp.
Description
Technical field
The utility model relates to the road lighting technical field, particularly a kind of LED road lamp cap.
Background technology
Along with the development trend of energy-saving and emission-reduction, LED obtains application more and more widely with characteristics such as its energy-conserving and environment-protective, luminous efficiency height, life-span length, and the trend that replaces the conventional road lamp lighting is arranged greatly at present.
In existing LED lighting, adopt the integral design pattern usually, be about to led light source and be soldered on the monoblock aluminium base, be fixed on then on the radiator, be closed in the lamp housing again.Because fin is closeer, the circulation of air between the fin has some setbacks, and NATURAL CONVECTION COEFFICIENT OF HEAT is very low, causes radiating effect undesirable, can't satisfy the heat radiation requirement of LED illuminating lamp, and then influences the service life of whole LED illuminating lamp.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of LED road lamp cap, it can overcome LED lighting radiator and be enclosed in the circulation of air that causes in the lamp housing and have some setbacks, the problem that NATURAL CONVECTION COEFFICIENT OF HEAT is low to improve the radiating effect of LED lamp, improves the life-span of light fixture.
The technical scheme that the utility model technical solution problem adopts is:
A kind of LED road lamp cap, comprise lamp housing, at least one LED module and power module, described those LED modules and power module are arranged in the described lamp housing, this lamp housing comprises lamp housing and following lamp housing, it is characterized in that, described going up on the lamp housing arranges several louvres, described lamp housing down arranges some osculums, described lamp housing down, LED module and power module leave the gap between any two, described louvre and described lamp housing down, the gap that LED module and power module leave between any two forms a heat dissipation channel, and described louvre also forms another heat dissipation channel with osculum simultaneously.
The beneficial effects of the utility model are:
The utility model utilizes hot cellular effect at inner two heat dissipation paths that form of lamp housing originally sluggish in air circulation, makes cross-ventilation, fully passes through the space between the module, takes away heat rapidly, effectively reduces the temperature of LED lamp, improves the life-span of light fixture.
In addition, the utility model uses the module support of originally just playing a supporting role cleverly, make it become " heat conduction support ", the heat that module is produced conducts to the lamp housing that originally just plays the structural member effect, make it assist the module radiator heat-dissipation, the surface area of bar structure spare fully utilizes, and it is participated in to the transfer of air heat.The utility model has designed the screwless structure simultaneously, avoids steam to pass through the infiltration of screw hole, with double silicon rubber loop led chip is thoroughly completely cut off with extraneous, stops all steam or other pernicious gases and corrodes chip and pcb board.This design except common test under water, is also passed through 100 degrees centigrade boiling red ink test to boil water by harsh experimental demonstration.In the double protection, each road all will experience more than 30 minutes, puts into the cold water of room temperature after having boiled immediately, examines its waterproof ability with quenching.The above to boil water and quenching test of 6 circulations in 3 hours has been experienced in double protection together.

The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is elaborated further.
A kind of LED road lamp cap, comprise lamp housing, two LED modules 4 and a power module 5, described those LED modules 4 and power module 5 are arranged in the described lamp housing, this lamp housing comprises lamp housing 1 and following lamp housing 6, it is characterized in that, described going up on the lamp housing 1 arranges 21 louvres 2, on the lamp housing 6 15 osculums 7 are set under described, described lamp housing 6 down, LED module 4 and power module 5 leave gap 3 between any two, described louvre 2 and described lamp housing 6 down, the gap 3 that LED module 4 and power module 5 leave between any two forms a heat dissipation channel, and described louvre 2 also forms another heat dissipation channel with osculum 7 simultaneously.
