Embodiment Construction

[0012] The present invention will be described in further detail below by means of specific embodiments:

[0013] The reference signs in the accompanying drawings of the specification include: a housing 10 , a reflective cup 20 , an LED bulb 30 , a lens 40 , and a dustproof cover 50 .

[0014] The embodiment is basically as attached figure 1 As shown: a lamp with extended irradiation distance, including a housing 10, an LED bulb 30 located in the housing 10, and a reflector 20 covering the periphery of the LED bulb 30 and connected to the housing 10; the lamp also includes a plurality of The lens 40 connected to the reflector cup 20 along its circumference is in the shape of a ring, and the surface of the lens 40 close to the LED bulb 30 is serrated, and the other surface of the lens 40 is flat. The inner diameters of the lenses 40 are the same, so that the light parallel to the center line of the reflector cup 20 in the LED bulb 30 can be prevented from weakening as much as ...

Abstract

The invention belongs to the field of lighting devices and specifically discloses a lamp capable of increasing an irradiation distance. The lamp comprises a housing, an LED lamp bulb located within the housing, and a reflecting cup arranged to cover the LED lamp bulb and connected with the housing; the lamp further comprises a plurality of lenses connected with the reflecting cup in a circumferential direction; each lens is circular-ring-shaped, and a face, close to the LED lamp bulb, of the lens is toothed, while the other face of the lens is a plane. The lamp is capable of increasing the irradiation distance.

Description

technical field [0001] The invention relates to the field of lighting devices, in particular to a lamp for extending the irradiation distance. Background technique [0002] As a new type of high-efficiency solid light source, LED lamps have significant advantages such as high luminous efficiency, long service life, energy saving and environmental protection, rich colors, flexible and controllable, fast response, miniaturization, easy integration, safety and reliability, and are the most promising in the 21st century. green lighting source. LED lighting sources have been widely used in landscape lighting, street lighting, large-screen display, backlight and other fields. [0003] At present, most of the high-power LED lamps are wide, and the light is distributed in the form of a single reflector, and the LED bulb is set at the bottom of the reflector. Part of the light emitted by the LED bulb is directly irradiated through the opening of the reflector, and the other part is...
