Abstract
The utility model discloses an LED bulb which comprises a bulb casing, a bulb holder, a circuit board, a radiating seat, an LED lamp and an optical lamp shade. The lamp holder is arranged on the upper end portion of the lamp casing, the optical lamp shade is arranged on the lower end portion of the lamp casing, the radiating seat is installed in the lamp casing, the circuit board is installed on the lower end portion of the radiating seat, the LED lamp is arranged on the circuit board, and a luminous surface of the LED lamp faces towards the optical lamp shade; and a plurality of cold air inlets are arranged on the lower portion of the lamp casing, and a plurality of hot air outlets forming convection with the cold air inlets are arranged on the upper portion of the lamp casing. The LED bulb has the advantages that the cold air inlets and the hot air outlets can perform radiating on the LED bulb respectively, so that the radiating effect of the LED bulb is improved; and simultaneously, by means of the air convection between the cold air inlets and the hot air outlets, the air flow around the radiating seat is good, the radiating effect of the LED bulb is further improved, and the LED bulb service life is prolonged effectively.
Description
Technical field
The utility model relates to a kind of LED bulb lamp.
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, radiating seat, LED lamp and optical lampshade, lamp holder is installed in the upper end of lamp housing, and optical lampshade is installed in the bottom of lamp housing, and circuit board is located at the lower end in the lamp housing, the LED lamp is installed on the circuit board, and the light-emitting area of LED lamp is towards optical lampshade, and radiating seat is located in the lamp housing and is in the top of circuit board, and the outer shroud pressed on ring of radiating seat is arranged with some radiating fins.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, in use the LED lantern festival produces heat, the heat that the LED lamp produces though the radiating fin of its radiating seat can leave effectively, but radiating seat is sealed in the lamp housing, and its ambient air flows comparatively not good, easily causes the radiating effect of fin relatively poor, make the radiating effect of LED bulb lamp poor, thereby shortened the service life of LED bulb lamp.
In view of above-mentioned reason, the inventor conducts in-depth research the structure of LED bulb lamp, and this case produces thus.
The utility model content
The purpose of this utility model provides a kind of LED bulb lamp of good heat dissipation effect.
The technical solution of the utility model is such: a kind of LED bulb lamp, include lamp housing, lamp holder, circuit board, radiating seat, 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, radiating seat is installed in the lamp housing, circuit board is installed on the bottom of radiating seat, and the LED lamp is installed on the circuit board, and the light-emitting area of LED lamp is towards optical lampshade; The bottom of above-mentioned lamp housing is provided with several cold wind imports, and the top of above-mentioned lamp housing is provided with the hot-blast outlet that several and above-mentioned cold wind import form convection action.
Above-mentioned cold wind import is in the below of above-mentioned radiating seat, and above-mentioned hot-blast outlet is in the top of above-mentioned radiating seat.
Each above-mentioned hot-blast outlet is respectively around the upper end place that is arranged on above-mentioned lamp housing, and each above-mentioned hot-blast outlet is through hole.
The lower end surface pressed on ring of above-mentioned lamp housing is arranged with the breach that several intervals arrange, and each above-mentioned breach forms above-mentioned cold wind import.
After adopting technique scheme, a kind of LED bulb lamp of the present utility model, because the bottom of lamp housing is provided with several cold wind imports, the top of lamp housing is provided with the hot-blast outlet that several and cold wind import form convection action, like this, in use, except radiating seat can play the thermolysis the heat that LED lamp source produces, cold wind import and hot-blast outlet itself also can play respectively the thermolysis to the LED bulb lamp, improved the radiating effect of LED bulb lamp, simultaneously, utilize the cross-ventilation effect between cold wind import and the hot-blast outlet, it is better that the radiating seat ambient air is flowed, and further improved the radiating effect of LED bulb lamp, effectively prolonged the service life of LED bulb lamp.
Description of drawings
Fig. 1 is stereogram of the present utility model.
Among the figure:
Lamp housing 1 hot-blast outlet 11
Cold wind import 12 lamp holders 2
Optical lampshade 3
The specific embodiment
A kind of LED bulb lamp of the present utility model, as shown in Figure 1, include lamp housing 1, lamp holder 2, optical lampshade 3, the radiating seat (not shown), circuit board (not shown) and LED lamp (not shown), lamp holder 2 is installed in the upper end of lamp housing 1, optical lampshade 3 is installed in the bottom of lamp housing 1, the radiating seat (not shown) is installed in the lamp housing 1, the circuit board (not shown) is installed on the bottom of radiating seat, LED lamp (not shown) is installed on the circuit board (not shown), and the light-emitting area of LED lamp (not shown) is towards optical lampshade 3.
Improvements of the present utility model are: the upper end place of lamp housing 1 is around being provided with several hot-blast outlets 11, this hot-blast outlet 11 is in the top of radiating seat, and hot-blast outlet 11 is through hole, several intervals arrange around being provided with at the lower end surface place of lamp housing 1, and forming the cold wind import 12 of convection action with each hot-blast outlet 11, this cold wind import 12 is the sawtooth breach.
A kind of LED bulb lamp of the present utility model, in use, can respectively cool ambient air be introduced lamp housing 1 interior chamber temp to lamp housing 1 by hot-blast outlet 11 and cold wind import 12 lowers the temperature, then the LED bulb lamp can play the thermolysis the heat that LED lamp source produces except radiating seat, the thermolysis that hot-blast outlet 11 and cold wind import 12 itself also can be played respectively LED lamp source, improved the radiating effect of LED bulb lamp, simultaneously, utilize the cross-ventilation effect between cold wind import 12 and the hot-blast outlet 11, it is better that the radiating seat ambient air is flowed, further improve the radiating effect of LED bulb lamp, thereby effectively prolonged the service life of LED bulb lamp.
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.
