The face that said optical profile type lampshade contacts with LED lamp pearl is an incidence surface; The face that LED lamp pearl contacts with the optical profile type lampshade is an exiting surface; Light directly gets into the optical profile type lampshade from incidence surface after the exiting surface of LED lamp pearl penetrates, the direction that the adjusting directive through positive camber in the optical profile type lampshade shines.
As optimal way, said optical profile type lampshade is hollow segment globe holder, and the aluminium base bending forming is circular.
As optimal way, said optical profile type lampshade is solid segment globe holder, and the aluminium base bending forming is circular.
As optimal way, said optical profile type lampshade is the bar shaped lampshade, and aluminium base is configured as bar shaped.
As optimal way, said optical profile type lampshade is circular lampshade, and the aluminium base bending forming is circular.
First kind, second kind, the 4th kind preferred construction according to front optical profile type lampshade is provided with the plurality of V-shaped groove on the said optical profile type lampshade, corresponds respectively to the midway of per two adjacent LED lamp pearls.More precisely, these V-type grooves correspond respectively to the centre position between the exiting surfaces of per two adjacent LED lamp pearls.The beneficial effect that these V-type grooves are set is with the light direction of the horizontal high angle scattered light of minute surface reflection adjustment LED lamp pearl, thereby to improve the light fixture light extraction efficiency.
In sum, owing to adopted technique scheme, the beneficial effect of the utility model is:
The mounting means that aluminium base is installed has increased substrate of LED lamp pearl and the heat transfer area between the lamp outer casing, has reduced thermal resistance, has improved radiating efficiency, more effectively guarantees the service life of LED lamp pearl;
LED lamp integument is hidden in the mode of optical profile type lampshade lateral surface; Avoided the direct projection of LED spot light, eliminated the stimulation of LED spot light to human eye, light transmits in the optics lampshade of high transmission rate; Arrangement, distribution through external curve in the optical profile type lampshade; With the mode of total reflection and refraction, the directive target direction has improved utilization ratio of optical energy.
