Abstract
The utility model discloses a light-emitting diode (LED) bulb lamp radiator which comprises a hollow circular cylinder and a plurality of radiating fins which are evenly erected at intervals on an outer side wall of the hollow circular cylinder, and the radiating fins are connected with the hollow circular cylinder in a detachable mode. After the technical scheme is adopted, according to the LED bulb lamp radiator, the radiating fins and the hollow circular cylinder are connected in a detachable mode, that is, the radiating fins and the hollow circular cylinder are arranged in a split mode, thus, the radiating fins can be manufactured into a sheet structure, and the occupied space of the radiating fins is relatively small, so that more radiating fins can be mounted on the outer side wall of the hollow circular cylinder, radiating effects of the radiator are good, and the problem that service life of the LED bulb lamp is short caused by fewer radiating fins on a traditional LED bulb lamp radiator is solved.
Description
Technical field
The utility model relates to a kind of parts of LED bulb lamp, particularly a kind of radiator.
Background technology
Traditional bulb is incandescent light bulb, and ubiquity has brightness lower, and light is not bright, not energy-conservation shortcoming.In order to solve this defective, a kind of LED bulb lamp has appearred on the market, it includes lamp housing, lamp holder, circuit board, radiator, LED lamp and optical lampshade, lamp holder is installed in the upper end of lamp housing, optical lampshade is installed in the bottom of lamp housing, radiator is located in the lamp housing, circuit board is installed on the lower end surface of radiator, the LED lamp is installed on the circuit board, and the light-emitting area of LED lamp is towards optical lampshade, and this radiator comprises hollow circular cylinder and around some radiating fins on the lateral wall of being located at hollow circular cylinder.This LED bulb lamp, its light source adopts the led light source of comparatively energy-conservation and environmental protection, makes the LED bulb lamp have the characteristics of energy-saving and environmental protection, deeply is subjected to consumers in general's hobby.Yet, existing LED bulb lamp, each radiating fin and the hollow circular cylinder of its radiator are integrated injection moldings, be subjected to the restriction of manufacture craft, radiating fin can only form the sheet structure, can't form flake structure, thereby the space that radiating fin is occupied is larger, cause the quantity of the radiating fin on the lateral wall of hollow circular cylinder comparatively limited, and, the main radiating surface of radiating fin (main radiating surface is a pair of side of radiating fin area maximum, namely adjacent radiating fin mutually in the face of or back to face) be planar structure, and then make the radiating effect of radiator comparatively not good, cause the service life of LED bulb lamp shorter.
In view of above-mentioned reason, the inventor conducts in-depth research the structure of the radiator of LED bulb lamp, and this case produces thus.
The utility model content
The purpose of this utility model provides a kind of radiator of LED bulb lamp of excellent in heat dissipation effect.
The technical solution of the utility model is such: a kind of radiator of LED bulb lamp, comprise hollow circular cylinder and some radiating fins, each radiating fin is evenly spaced to be erected on the lateral wall of hollow circular cylinder, and above-mentioned radiating fin and above-mentioned hollow circular cylinder are for removably connecting.
Offer the installation groove of installing for the corresponding insertion of each above-mentioned radiating fin on the lateral wall of above-mentioned hollow circular cylinder, and the lateral wall of above-mentioned hollow circular cylinder offers the fin riveted groove that above-mentioned radiating fin is riveting in the above-mentioned installation groove at the position between the above-mentioned installation groove in twos.
The main radiating surface of above-mentioned radiating fin is wavy surface.
After adopting technique scheme, the radiator of a kind of LED bulb lamp of the present utility model, because radiating fin and hollow circular cylinder are for removably connecting, be that radiating fin and hollow circular cylinder are the split setting, radiating fin can be made into flake structure like this, make taking up space of radiating fin less, thereby make the radiating fin that a greater number can be installed on the lateral wall of hollow circular cylinder, and then making the radiating effect of radiator better, the radiator of having avoided traditional LED bulb lamp causes the short problem in service life of LED bulb lamp because of the negligible amounts of radiating fin on it; Because the main radiating surface of radiating fin is wavy surface, has increased the area of dissipation of each radiating fin, thereby can further improve the integral heat sink effect of radiator again.
Description of drawings
Fig. 1 is stereogram of the present utility model;
Fig. 2 is the enlarged drawing of A section among Fig. 1.
Among the figure:
Hollow circular cylinder 1 is installed groove 11
Fin riveted groove 12 radiating fins 2
The specific embodiment
The radiator of a kind of LED bulb lamp of the present utility model, as shown in Figure 1, 2, comprise hollow circular cylinder 1 and some radiating fins 2, each radiating fin 2 evenly spaced setting is installed on the lateral wall of hollow circular cylinder 1, and radiating fin 2 and hollow circular cylinder 1 are for removably connecting.Particularly, offer the installation groove 11 of installing for the 2 corresponding insertions of each radiating fin on the lateral wall of hollow circular cylinder 1, and the lateral wall of hollow circular cylinder 1 in that being installed in twos, position between the groove 11 offering and radiating fin 2 is riveting in the fin riveted groove 12 of installing in the groove 11.
The radiator of a kind of LED bulb lamp of the present utility model, during making, make respectively first hollow circular cylinder 1 and each radiating fin 2, and then each radiating fin 2 corresponding insertion respectively installed in the groove 11, last riveting tool inserts fin riveted groove 12 interior radiating fin 2 is riveting in and installs in the groove 11, can finish like this installation of radiating fin 2.
The radiator of a kind of LED bulb lamp of the present utility model, because radiating fin 2 and hollow circular cylinder 1 are for removably connecting, be that radiating fin 2 is the split setting with hollow circular cylinder 1, can distinguish independent the making, radiating fin 2 is not subjected to the process technology limit of integral molded plastic, can be made into flake structure, make taking up space of radiating fin 2 less, thereby make the radiating fin 2 that a greater number can be installed on the lateral wall of hollow circular cylinder 1, and then making the radiating effect of radiator better, the radiator of having avoided traditional LED bulb lamp causes the short problem in service life of LED bulb lamp because of the negligible amounts of radiating fin on it 2.
In the utility model, in order further to improve the integral heat sink effect of radiator, can (main radiating surface be a pair of side of radiating fin area maximum with the main radiating surface of radiating fin 2, be adjacent radiating fin mutually in the face of or back to face) all be arranged to wavy surface, can increase like this area of dissipation of radiating fin 2 by this wavy surface.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
