A kind of LED bulb, including Lamp cup, LED light source board and the LED light source being arranged in the LED light source board, at least one
Strip lens, the LED light source board are arranged on the Lamp cup and are thermally connected with the Lamp cup, and the strip lens are arranged on the LED
The top of light source causes the light that the LED light source is sent to enter the bottom surface of the strip lens, the side wall of the strip lens
Reflective surface and light-emitting surface are respectively formed, which is used to reflect light that the LED light source sends towards light-emitting surface and makes light
Line outwards projects after light-emitting surface refraction.
Compared to the prior art, strip lens are provided in LED bulb of the present invention, the light that LED light source is sent enters item
It is provided with reflective surface and light-emitting surface in shape lens, on strip lens, light is by the bottom of strip lens to can be according to during top conduction
It is emitted after the reflection of the secondary reflective surface through strip lens, the refraction of light-emitting surface, so as to which the effect of string light be presented, while can shine
Bright light blister has the illumination effect of conventional incandescent.

Fig. 2 is the cross-sectional view after the assembling of LED bulb shown in Fig. 1；
Fig. 3 is the light path schematic diagram of LED bulb shown in Fig. 2.
Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and embodiments.
Please refer to Fig.1 to Fig. 3, a kind of LED bulb of the invention, the LED bulb include Lamp cup 10, LED light source board 20 and
LED light source 21, at least one strip lens 31 being arranged in the LED light source board 20, the LED light source board 20 are arranged on the Lamp cup
It is thermally connected on 10 and with the Lamp cup 10, strip lens 31 are arranged on the top of LED light source 31 so that the light that LED light source 31 is sent
Into the bottom surface of strip lens 31.
Wherein, the side wall of strip lens 31 is respectively formed reflective surface 311 and light-emitting surface 312, which is used for direction
Light that 312 reflex LED light source of light-emitting surface is sent simultaneously makes light outwards be projected after the light-emitting surface 312 refraction.It specifically, should
Diffusing reflection coating is coated on reflective surface 311.The light-emitting surface 312 is annuli arrangement, which connects with the reflective surface 311
The side wall of composition strip lens 31 is connect, which is used to expand the distribution angle of the light of the reflective surface 311 reflection, such as
Shown in Fig. 3, this some light can be emitted by the bottom conductive of strip lens 31 to top by the light-emitting surface 312 of strip lens 31
Top, side wall and the bottom of bulb housing are illuminated afterwards.
LED bulb 100 of the present invention, including more than two strip lens 31, strip lens 31 surround the LED light source board 20
Center arrange in a ring, the reflective surfaces 311 of strip lens 31 is close to the centrally disposed with by LED light of the LED light source board 20
The light direction that source 21 is sent is around the space reflection at the center of the LED light source board 20.In the present embodiment, with tool, there are four strips
Illustrate exemplified by lens 31.Strip lens 31 are directed away from 20 center of LED light source board on the direction away from the LED light source board 20
Direction bending set, the projection of the reflective surfaces 311 of strip lens 31 in the LED light source board 20 covers the LED light source board 20
On part LED light source.The bending of strip lens 31 is set, and light is contributed to be reflected towards bottom, expands light emitting angle, forms big angle
Spend illumination effect.
Wherein, middle part lens 32 are further included, which corresponds to the LED light source 21 at the middle part of the LED light source board 20
It sets, which is used to reflect the light that middle part LED light source 21 is sent 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 tops of the middle part lens 32 is umbrella shape reflective surface 321, the fan
Shape reflective surface 321 contributes to light to be irradiated towards bulb housing bottom, supplement irradiation towards the bottom reflection light of the strip lens 31
To the light of bulb housing bottom.
LED bulb 100 of the present invention, further includes bulb housing 40, the bulb housing 40 be bottom opening shell structure, the light bulb
