Abstract
A large-angle light-emitting LED lamp comprises a lamp head body, a bulb outer shell, a bulb inner shell and an LED light source plate. The LED light source plate is arranged at the top of the lamp head body. The bottom of the bulb outer shell is arranged at the top end of the lamp head body in a covering mode. The LED light source plate comprises a base plate and an LED light source arranged on the base plate. The bottom of the bulb inner shell is arranged on the LED light source in a covering mode. A light reflecting piece is arranged on the top face of the bulb inner shell. Through the light reflecting piece, part of light emitted by the LED light source can be emitted to the top of the bulb outer shell in a transmitting mode. The light reflecting piece can reflect the other part of the light emitted by the LED light source to the bottom of the bulb outer shell, accordingly the light-emitting angle of the whole lamp is enlarged, and optical efficiency is improved. A support does not need to be arranged, a plurality of LED light sources do not need to be arranged on the side face of the support in a welding mode, so that the structure is simplified, and accordingly the large-angle light-emitting LED lamp has the advantages of being simple in structure and large in light-emitting angle.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail.
Fig. 1 is the exploded view of the utility model wide-angle light emitting LED lamp 100, this wide-angle light emitting LED lamp 100 comprises body 40, bulb shell 10, bulb inner casing 20 and LED light source plate 30, this LED light source plate 30 is arranged on the top of this body 40, the bottom cover of this bulb shell 10 is located at the top of this body 40, this LED light source plate 30 comprises substrate 31 and is arranged on the LED light source 32 on this substrate, the bottom cover of this bulb inner casing 20 is established these LED light sources 32, the end face of this bulb inner casing 20 is provided with reflecting component 21, this reflecting component 21 can allow the top of this bulb shell 10 of part light transmission directive that this LED light source 32 sends, this reflecting component 21 can make other part light that this LED light source 32 the sends bottom reflection towards this bulb shell 10.
Please refer to Fig. 1, these body 40 tops are provided with coniform boss 41, and the side of this boss 41 is provided with reflecting layer (not shown).
Please refer to Fig. 2, this LED light source plate 30 comprises substrate 31 and is arranged on the LED light source 32 on this substrate, and this LED light source plate 30 is arranged on the end face of the boss 41 of this body 40.This substrate 31 is slab construction, and these LED light sources 32 are concentrated the centre position that is arranged in this substrate 31.
Please refer to Fig. 1, the bottom cover of this bulb shell 10 is located at the top of this body 40, preferred, and this bulb shell 10 is transparent hemisphere cell-shell excessively.
Please refer to Fig. 1, the bottom cover of this bulb inner casing 20 is established the LED light source 32 of these LED light source plates 30, and the end face of this bulb inner casing 20 is provided with reflecting component 21, and this reflecting component 21 is for being coated in the diffuse reflector of these bulb inner casing 20 end faces, preferably, this reflecting component 21 is white ink coating.The light reflectivity of this reflecting component 21 is 70%-85%, and the light transmission of this reflecting component 21 is 15%-30%.The LED light source 32 that the area of this reflecting component 21 is greater than these LED light source plates 30 surrounds the area in region.This bulb inner casing 20 is reverse frustoconic shell structure.The size of this reflecting component 21 is less than the diameter of these bulb inner casing 20 maximums.The top of this bulb shell 10 of part light transmission directive that this reflecting component 21 can send the LED light source of this LED light source plate 30, part light is towards the bottom reflection of this bulb shell 10.Preferably, the sidewall of this bulb inner casing 20 is provided with light diffusing material, and these illumination of reflecting via reflecting component 21 scatter to this bulb shell 10 after being mapped to the light diffusing material of this bulb inner casing 20.
