Abstract

The invention relates to a lamp which comprises a light-emitting diode (LED) light source, a diffusion shell, a base plate and a driving power supply for supplying power to the LED light source. The LED light source and the driving power supply are arranged in a cavity defined by the diffusion shell and the base plate. The lamp further comprises a light guiding component for guiding a part of light emitted by the LED light source to the portion of the diffusion shell right opposite to the driving power supply. By arranging the light guiding component for guiding a part of the light emitted by the LED light source to the portion of the diffusion shell right opposite to the driving power supply, the phenomenon that the portion of the diffusion shell right opposite to the driving power supply is weak in light can be avoided, and light of the whole diffusion shell can be even.

Preferably, described spreadlight lens is provided with installed surface, and the local inner concave of described installed surface forms arc surface, and described arc surface is described incidence surface.
Preferably, described exiting surface is obliquely installed with respect to described base plate.
Preferably, described reflecting surface is the arcuate flanks that connects described installed surface and described exiting surface.
Preferably, described exiting surface is made up of some convex lens faces.
Preferably, described light guide member is reflector, and described reflector is provided with the just reflecting surface at the position to described driving power to described diffusion shell by the part light reflection of described LED light source.
Preferably, described reflector is provided with through hole, and described driving power is arranged in described through hole, the reflecting surface that the lateral surface of described reflector is described reflector.
Preferably, the reflecting surface of described reflector is obliquely installed with respect to described base plate.
Preferably, described driving power is installed on the center of described base plate, and described LED light source is distributed on described driving power around.
By being set, the light that described part LED light source is sent guides to the just light guide member at the position to described driving power of described diffusion shell, can avoid diffusion shell just to the position light of described driving power a little less than, thereby make the light of whole diffusion shell comparatively even.
