Abstract

The utility model relates to a lighting lamp which comprises a light-emitting diode (LED) light source, a diffusion cover, a base plate and a driving power supply which is used for supplying electricity for the LED light source. The LED light source and the driving power supply are arranged in a cavity formed by the diffusion cover and the base plate. The lighting lamp further comprises a light leading component which is used for leading a part of light emitted from the LED source to the position, directly facing the driving power supply, of the diffusion cover. Due to the arrangement of the light leading component which is used for leading the part of light emitted from the LED source to the position, directly facing the driving power supply, of the diffusion cover, the fact that light of the position, directly facing the driving power supply, of the diffusion cover is weaker is avoided, and light of the whole diffusion cover is enabled to be uniform.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of illuminator.

In order to solve above technical problem, illuminator of the present utility model includes LED light source, diffusion shell, base plate and the driving power supply for being powered to the LED light source, the LED light source and driving power supply are arranged in the cavity surrounded by the diffusion shell and the base plate, the illuminator also includes the light that sends a part of LED light source and guided to the light guide member just to the position of the driving power supply of the diffusion shell, and the rated power of the illuminator is more than or equal to 0.1 watt.

Preferably, the light guide member is spreadlight lens, and the spreadlight lens includes incidence surface, reflecting surface and exiting surface；The light that the LED light source is sent enters the spreadlight lens from the incidence surface, then by reaching the position just to the driving power supply of the diffusion shell after the reflective surface to the exiting surface.

Preferably, the spreadlight lens is provided with mounting surface, and the local inner concave of the mounting surface forms arc surface, and the arc surface is the incidence surface.

Preferably, the exiting surface is obliquely installed relative to the base plate.

Preferably, the reflecting surface is the arcuate flanks for connecting the mounting surface and the exiting surface.

Preferably, the exiting surface is made up of some convex lens faces.

Preferably, the light guide member is reflector, and the reflector is provided with the reflecting surface just to the position of the driving power supply that some light of the LED light source is reflexed to the diffusion shell.

Preferably, the reflector is provided with through hole, and the driving power supply is arranged in the through hole, and the lateral surface of the reflector is the reflecting surface of the reflector.

Preferably, the reflecting surface of the reflector is obliquely installed relative to the base plate.

Preferably, the driving power supply is installed on the center of the base plate, and the LED light source is distributed on around the driving power supply.

Guided by setting the light for sending a part of LED light source to the light guide member just to the position of the driving power supply of the diffusion shell, the just weaker to the position light of the driving power supply of diffusion shell can be avoided, so that the light of whole diffusion shell is more uniform.
