Embodiment Construction

[0051] Please refer to Figure 1 to Figure 5 and Figure 13 , Figure 17 , the LED light ventilation window 26 in the figure includes 1 vent group, 2 outer panels 27 that are symmetrically arranged to press the light bar assembly 25, and 2 are located inside the outer panel 27 and are also symmetrically arranged on the inner side. Plate 28; the vent group has four vents 29 in total, and these vents 29 are trumpet-shaped and arranged symmetrically up, down, left and right respectively. The outer plate 27 on each side is combined with the inner plate 28 to form a groove shape such as a "V" groove, and the outer plate 27 on both sides is combined with the inner plate 28 to form the main frame of the ventilation window. In order to install the ventilation window on the bulb, a top mounting block 30 is specially installed on the top of the outer plate 27 . In order to install the ventilation window on the radiator, a locking buckle 31 arranged symmetrically on the left and right...

Abstract

The invention discloses a large-angle light-emitting breathing type heat-radiation LED bulb which comprises a lampshade, an LED lamp light source, a radiator, a lamp holder, a lamp holder base and a ventilating window. The lampshade comprises at least two lampshade light-emitting faces. The lampshade light-emitting faces are radially arranged in the peripheral direction of the lamp holder at intervals. The radiator comprises an upper cover and a lower cover. The upper cover comprises an upper cover lamp base and at least two upper cover heat conducting columns. The upper cover heat conducting columns are radially arranged under the upper cover lamp base at intervals, an upper ventilating cavity for installing a part of the ventilating window is arranged between adjacent upper cover heat conducting columns. The lower cover comprises an installing base and lower cover heat conducting columns corresponding to the upper cover heat conducting columns. The lower cover heat conducting columns are radially arranged above the installing base at intervals, a lower ventilating cavity for installing the remaining portion of the ventilating window is arranged between adjacent lower cover heat conducting columns, and the installing base is connected with the lamp holder base. The technical problems of poor heat radiation performance and a small light-emitting angle of the bulb can be solved.

Description

technical field [0001] The invention relates to a large-angle light-emitting breathing type heat-dissipating LED light bulb. Background technique [0002] The LED light bulbs currently used in the market mainly include lampshades, light source components, radiators, and lamp bases. Some LED lights also use ventilation windows. The above-mentioned components used in the prior art have many defects. The following details describe. [0003] At present, the lampshade used on the LED lamp is closed as a whole, but an opening is opened at the end for installing the lamp holder. This closed lampshade heat dissipation method is mainly to exchange heat between the outer surface of the radiator and the outside air to dissipate heat, and the air cannot enter the bulb, so that the overall heat dissipation performance of the bulb is poor, which seriously affects the service life of the bulb. In addition, At present, the lampshade and the lamp base are mostly fixed and glued together by...
