Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 be refer to Fig. 3, a kind of LED bulb of the present utility model, the LED bulb includes Lamp cup 10, LED light source plate 20 and LED/light source 21, at least one strip lens 31 for being arranged on the LED light source plate 20, the LED light source plate 20 is arranged on this On Lamp cup 10 and thermally coupled with the Lamp cup 10, strip lens 31 are arranged on the top of LED/light source 31 so that what LED/light source 31 was sent Light enters the bottom surface of strip lens 31.

Wherein, the side wall of strip lens 31 forms reflective surface 311 and exiting surface 312 respectively, and the reflective surface 311 is used for direction Light that the reflex LED light source of exiting surface 312 is sent simultaneously makes light outwards be projected after the exiting surface 312 refraction.Specifically, should Diffusing reflection coating is coated with reflective surface 311.The exiting surface 312 is annuli arrangement, and the exiting surface 312 connects with the reflective surface 311 The side wall of composition strip lens 31 is connect, the exiting surface 312 is used for the distribution angle for expanding the light of the reflective surface 311 reflection, such as Shown in Fig. 3, this some light can be by the bottom conductive of strip lens 31 to top, by the outgoing of exiting surface 312 of strip lens 31 Top, side wall and the bottom of bulb housing are illuminated afterwards.

The utility model LED bulb 100, including more than two strip lens 31, strip lens 31 surround the LED/light source The center of plate 20 is arranged in a ring, and the reflective surface 311 of strip lens 31 is close to the centrally disposed with general of the LED light source plate 20 Space reflection of the light that LED/light source 21 is sent towards the center around the LED light source plate 20.In the present embodiment, with four Explanation exemplified by individual strip lens 31.Strip lens 31 are directed away from the LED light source plate on the direction away from the LED light source plate 20 The direction bending at 20 centers is set, and the projection of the reflective surfaces 311 of strip lens 31 on the LED light source plate 20 covers the LED light Part LED/light source on source plate 20.The bending of strip lens 31 is set, and contributes to light to be reflected towards bottom, expands lighting angle, shape Into wide-angle illumination effect.

Wherein, in addition to middle part lens 32,32 pairs of the middle part lens should LED/light source plate 20 middle part LED/light source 21 Set, the light that the middle part lens 32 are used to send middle part LED/light source 21 is reflected towards the bottom of the strip lens 31.In this The bottom integrally connected of portion's lens 32 and strip lens 31 is set, and the top of the middle part lens 32 is umbrella shape reflective surface 321, the umbrella Shape reflective surface 321 contributes to light to be irradiated towards bulb housing bottom towards the bottom reflection light of the strip lens 31, supplement irradiation To the light of bulb housing bottom.
