Example Embodiment

[0035] See Figure 1 to Figure 3 A lamp provided by the embodiment of the present invention includes a lamp holder 10, a power module 20, a heat sink 30, a light emitting diode module 40, and a lamp shade 50.

[0036] The lamp holder 10 includes a receiving portion 11 at the bottom of the lamp holder 10 and a heat sink 30 at the top of the lamp holder 10. The receiving portion 11 includes an insulating portion 12 and an electrical connector 14. The electrical connector 14 is sleeved on the lower end of the insulating portion 12 and is used for electrical connection with an external power source to provide electrical energy required for the operation of the lamp. The insulating portion 12 is fixedly connected to the heat sink 30.

[0037] The power module 20 is disposed in the radiator 30 and is electrically connected to the electrical connector 14 on the receiving portion 11 and the light emitting diode module 40 to provide a driving voltage for the light emitting diode module 40...

Abstract

A lampshade has a light incident surface and a light exit surface, and several microstructures are formed on the light incident surface. Compared with the prior art, the light incident surface of the lampshade of the present invention has several microstructures, which reduces the total reflection probability of light incident on the light incident surface of the lampshade, improves the light output efficiency of the entire lamp, and reduces light loss. The invention also discloses a lamp.

Description

technical field [0001] The invention relates to a lighting device, in particular to a lampshade and a lamp using the lampshade. Background technique [0002] In order to protect the light-emitting device of the lamp, such as the light-emitting diode, a transparent lampshade is arranged on the light-emitting diode. Both the light-incident surface and the light-exit surface of the traditional lampshade are smooth, and part of the light incident on the light-incidence surface of the lampshade will undergo total reflection, which reduces the light-exit efficiency and increases light loss. Contents of the invention [0003] In view of this, it is necessary to provide a lampshade with improved light extraction efficiency and a lamp using the lampshade. [0004] A lampshade has a light-incident surface and a light-exit surface, and several microstructures are formed on the light-incidence surface. [0005] A lamp includes a lamp holder and a lampshade. The lamp holder and the l...
