Abstract

The utility model discloses a light emitting diode (LED) bulb capable of emitting light at large angles. The LED bulb comprises a freely replaceable reflective structure, a lampshade, a circuit board, a heat sink and a power connector. The freely replaceable reflective structure is arranged on the top of the lampshade; the top of the radiator is connected with the bottom of the lampshade; and the circuit board is provided with at least one LED assembly, the circuit board is arranged on one side of the heat sink, the lampshade covers the circuit board, light emitted by the LED assembly is irradiated to the lampshade and the freely replaceable reflective structure, and the power connector is arranged at the bottom of the heat sink. The LED bulb has the advantages that the light emitting angles of the LED bulb can be enlarged and can reach 270 to 330 degrees, and luminous intensity and brightness on the sides and the back are improved.

Description

But the LED bulb of wide-angle bright dipping

Technical field

But the utility model relates to a kind of LED bulb of wide-angle bright dipping, belong to the LED technical field.

Background technology

Existing LED bulb only comprises radiator, led light source, lampshade and lamp holder, does not have the catoptric arrangement of freely-removable, yet the lighting angle of existing LED bulb can only reach about 150 degree the luminous light intensity deficiency at side and rear, also bright inadequately.

Summary of the invention

But what the utility model proposed is a kind of LED bulb of wide-angle bright dipping, and its purpose is intended to set up catoptric arrangement, thereby the lighting angle of LED bulb is increased, and reaches 270 ~ 330 degree, and the luminous light intensity and the brightness at side and rear are obviously increased.

The technical solution of the utility model: its structure comprises catoptric arrangement, lampshade, circuit board, radiator and the power connection of freely-removable; Wherein the catoptric arrangement of freely-removable is arranged at the top of lampshade; The top and the lampshade bottom of radiator link; Be arranged to a rare LED assembly on the circuit board, circuit board is arranged on a place of radiator, and the lampshade cover covers circuit board; Have only being radiated on lampshade and the catoptric arrangement that a LED assembly sent at least, power connection is connected the radiator bottom.

The advantage of the utility model: the lighting angle that increases the LED bulb reaches 270 ~ 330 degree, and the luminous light intensity at LED bulb side and rear and brightness are increased; Can also let the user freely change this catoptric arrangement, improve that existing LED bulb lighting angle is little, the luminous light intensity at side and rear is not enough, defective such as bright inadequately.
