Abstract
A spot lamp with the effect of symmetrical heat radiation comprises an LED die set, a radiating body, a plastic connector, a lamp holder, a drive power supply and a drive circuit, wherein the drive power supply and the drive circuit are mounted in the radiating body. The spot lamp is characterized in that the plastic connector adopts a cylindrical structure, the upper part of the plastic connector is connected with the radiating body, the lower part of the plastic connector is connected with the lamp holder, and breather holes are distributed on the circumference in the middle of the cylindrical body of the plastic connector. The utility model ensures the practicability of the lamp holder of the spot lamp; moreover, the breather holes on the plastic connector can lead out the radiated heat inside the spot lamp, so that the temperature of the internal power supply is effectively lowered.
Description
[technical field]
The utility model relates to lighting field, relates in particular to the good shot-light of a kind of heat dispersion.
[background technology]
General finding shot-light all is made up of LED module, driving power, radiator, plastic cement connector several sections, the LED module all is installed in the Lamp cup, be coated with lens and cover above, a series of driving power circuit template of installing below of Lamp cup is that internal structure has been wrapped up in one section plastic cement connection between five metals head and radiator.
At present for the puzzlement of all shot-light maximums be exactly with how to solve the huge heat energy that LED produces in luminous, prolong whole service life, generally all adopt some male models producing bulb in the industry, be evenly equipped with some wing projectioies around the radiator on Lamp cup, but its heat-sinking capability is limited, can't be fine the problem of solution heat radiation.
So shot-light has concrete shape of some different models and lamp holder also can each to distinguish to some extent usually, the shot-light of picture thread head, its lamp holder has screw thread, can be used with the thread lamp socket knob, if the life-span that shot-light uses is shortened in the ventilative bad meeting of such a shot-light substructure heat radiation.
[summary of the invention]
At above problem, the utility model proposes especially that a kind of heat dispersion is better, illumination is more stable, can prolong the symmetry heat radiation shot-light in the illumination life-span of shot-light.
The technical solution of the utility model is: a kind of shot-light, comprise LED module, radiator, plastic cement connector, lamp holder and be installed in radiator interior driving power and drive circuit, it is characterized in that, its plastic cement connector is a cylindrical structure, top connects radiator, the lower part connects lamp holder, and air-vent is circumferentially arranged in the middle of cylinder.
Described air-vent has two at least, if even numbers is individual, then is symmetrically distributed;
If it is individual that described air-vent has odd number, then be uniformly distributed along the circumference.
Beneficial effect: the utility model had both guaranteed the practicality of the lamp holder of this shot-light, and the air-vent of offering on the plastic cement connector can be derived the inner heat that distributes then, effectively reduces the temperature on the internal electric source.
[description of drawings]
Fig. 1 is the perspective internal view of the utility model embodiment;
Fig. 2 is the utility model surface structure schematic diagram.
[specific embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.
Embodiment 1: a kind of shot-light, comprise LED module 1, radiator 2, plastic cement connector 3, lamp holder 4 and be installed in driving power 6 and drive circuit in the radiator 2, it is characterized in that, its plastic cement connector 3 is cylindrical structures, top connects radiator 2, the lower part connects lamp holder 4, and air-vent 5 is circumferentially arranged in the middle of cylinder.
Described air-vent has two at least, if even numbers is individual, then be symmetrically distributed, this air-vent mainly is that the unduly high temperature of driving power and drive circuit place can be flowed and distribute from the air-vent air, driving power is the important circuit part of lamp, in case under long-time the use, accumulate very high temperature and heat energy and will damage its function, influence its life-span, on the plastic cement connector, leave air-vent at this problem exactly so this use is novel, the air-vent that is symmetrically distributed, can allow outside air form convection current, for reducing internal temperature effect highly significant.
If it is individual that described air-vent has odd number, then be uniformly distributed along the circumference, press 120 ° of distributions for 3,5 then by 72 ° of distributions, by that analogy.
Claims (3)
1. symmetry heat radiation shot-light, comprise LED module, radiator, plastic cement connector, lamp holder and be installed in radiator interior driving power and drive circuit, it is characterized in that, its plastic cement connector is a cylindrical structure, top connects radiator, the lower part connects lamp holder, at the cylinder middle part of plastic cement connector air-vent is arranged circumferentially.
2. according to the described symmetry heat radiation of claim 1 shot-light, it is characterized in that described air-vent has two at least,, then be symmetrically distributed if even numbers is individual.
3. according to the described symmetry heat radiation shot-light of claim 1, it is characterized in that,, then be uniformly distributed along the circumference if described air-vent has odd number.
