Lens and LED bulkhead lamp

Abstract

The invention discloses a lens and an LED bulkhead lamp comprising the same. The outer outline of the lens is formed by connecting a bottom surface and a convex surface, wherein the convex surface is an outer curved surface of the lens, the bottom surface is a plane, the bottom surface is shaped as a circle, the bottom surface is provided with a hole slot, the outer outline of the hole slot is formed by connecting a hole slot bottom surface with a hole slot convex surface, the hole slot bottom surface is a plane and is shaped as a circle, the hole slot bottom surface and the lens bottom surface are on the same plane and concentric, the radius of the hole slot bottom surface is less than that of the lens bottom surface, and the hole slot convex surface is an inner curved surface of the lens. The LED bulkhead lamp is provided with a heat conducting device and can accelerate the speed of radiating heat. The lens provided by the invention is designed by adopting a method of combining the inner curved surface and the outer curved surface, is small and practical, is simple in manufacture, and can be used for uniform irradiation of a large-area light source; and the LED light source has better heat radiating performance, is nonuniform in illumination, and can be widely applied to the field of illumination.

Description

technical field [0001] The invention belongs to the field of lenses and industrial and mining lamps, and in particular relates to a thinner lens and an LED industrial and mining lamp with good heat dissipation performance and uniform illumination of the lens. Background technique [0002] In the published patent literature, the hole groove of the lens is mostly designed to be hemispherical, and the design method of the inner curved surface is not published. In this way, the lens can only be designed by using the change of the curve of the outer curved surface, resulting in a thicker designed lens. When used for a large-area light source, the lens volume is too large, which is not conducive to manufacturing. [0003] At present, industrial and mining lamps on the market generally use incandescent lamps or energy-saving lamps. There is no LED lamp for energy saving, and there is no LED lamp for longevity. The filament will turn black when it is started or turned off, and it w...

Problems solved by technology

[0005] In view of the above-mentioned shortcomings, the object of the present invention is to provide a lens, which effectively solves the problem that the lens in the prior art is relatively thick, and when used for a large-area light source, the lens volume is too large and is not conducive to manufacturing.

[0006] Another object of the present invention is to provide an LED industrial and mining lamp with good heat dissipation performance and uniform illumination, which can effectively solve the problems of poor heat dissipation performance and uneven illumination in the prior art
