Embodiment Construction

[0025] figure 1 Shown is a three-dimensional exploded view of the first embodiment of the large-angle LED lighting lamp of the present invention. The large-angle LED lighting lamp 100 includes a lamp head body 10 , a positioning platform 20 , six sets of identical light sources 30 , a reflector 40 and a bulb shell 50 . One end of the lamp body 10 is connected to the positioning platform 20 , and the other end is electrically connected to a lamp holder (not shown). The six groups of light sources 30 are respectively arranged on the positioning platform 20 . The reflective member 40 is disposed on the positioning platform 20 . The bottom of the bulb shell 50 is connected with the lamp body 10 to form a cavity for containing the positioning platform 20 , the light source 30 and the reflector 40 . The light bulb housing 50 is provided with a light-transmitting scattering material.

[0026] Please refer to figure 1 , image 3 and Figure 4 , each group of light sources 30 in...

Abstract

The invention discloses a large-angle light-emitting diode (LED) illuminating lamp, which comprises a lamp cap body, a positioning table and a plurality of light sources, wherein a bottom wall of the positioning table is fixed on the lamp cap body; the size of an opening of the bottom of a bulb shell is smaller than that of the middle part of the bulb shell; the bulb shell is provided with light penetrating scattering materials; the bulb shell is connected to the lamp cap body so as to receive the positioning table and the plurality of light sources; the light sources are arranged on a side wall of the positioning table; each light source comprises a lens and an LED chip; and the lens is used for distributing more light emitted by the LED chip in a direction partial to the lamp cap body. The large-angle LED illuminating lamp has the advantage of simple structure.

Description

technical field [0001] The invention relates to an LED lighting lamp, in particular to a large-angle LED lighting lamp. Background technique [0002] With the maturity of LED lighting technology, LED is widely used as a light source in the fields of indoor lighting and stage spotlights. However, due to the solid light emitting characteristics of the LED light source, it is difficult to make the whole light emit light at a large angle. In order to increase the luminous angle of the LED lighting lamp, people try to increase the luminous angle of the whole lamp by arranging the light source on the column. For example, Chinese utility model patent 200920205714.0 announced on June 9, 2010 discloses an LED lighting lamp. The LED lighting lamp comprises a lampshade and a base connected with the lampshade, a fixing seat is arranged in the cavity formed between the lampshade and the base, and a plurality of LEDs are arranged on the fixing seat, and the fixing seat is composed of se...
