Embodiment Construction

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0012] Please refer to Figure 1 to Figure 3 , an LED light bulb of the present invention, the LED light bulb includes a lamp cup 10, an LED light source board 20, an LED light source 21 arranged on the LED light source board 20, and at least one strip lens 31, and the LED light source board 20 is arranged on the LED light source board 20 On the lamp cup 10 and thermally connected with the lamp cup 10 , the strip lens 31 is arranged above the LED light source 31 so that the light emitted by the LED light source 31 enters the bottom surface of the strip lens 31 .

[0013] Wherein, the side walls of the strip lens 31 respectively form a reflective surface 311 and a light-emitting surface 312 , and the reflective surface 311 is used to reflect the light emitted by the LED light source toward the light-emitting surface 312 and make the light refra...

Abstract

The invention discloses a LED bulb, including a lamp cup, a LED light source plate, and LED light sources arranged on the LED light source plate, and at least a strip lens. The LED light source plateis arranged on the lamp cup and is connected with the lamp cup in a hot manner. The strip lenses are arranged on the LED light sources, so that light emitted by the LED light sources enters bottom surfaces of the strip lenses. Side walls of the strip lens respectively form a reflection plane and a light-out plane. The reflection plane is used to reflect light emitted by the LED light sources toward the light-out plane, so that the light emits outwards after the light being refracted by the light-out plane. The LED bulb has appearance of an incandescent lamp and luminescence effect of an incandescent lam, and manufacturing process is simple.

Description

technical field [0001] The invention relates to the field of LEDs, in particular to LED bulbs. Background technique [0002] LED light sources have the advantages of high luminous efficiency, low heat generation, power saving and long life, and have been widely used and gradually replaced traditional lighting fixtures such as incandescent lamps and halogen lamps. However, incandescent lamps have a long history, and their appearance and luminous effects have long been deeply rooted in the hearts of the people and are highly accepted. Therefore, LED lamps that imitate the appearance and luminous effects of incandescent lamps are very popular. [0003] In the prior art, LED light strips and transparent glass bubbles are commonly used to achieve the effect of incandescent lamps. This kind of scheme is difficult to assemble, the production efficiency is low, the light intensity in the center of the light distribution curve is weak, the light distribution curve is uneven, the fin...
