Embodiment Construction

[0031] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0032] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

An LED illumination lamp comprises a housing, a reflector, a transparent shade, and a plurality of LED light sources. The reflector is in a cone frustum structure and comprises a large end open and a small end which is closed and which is opposite to the large end; the outer periphery of the large end is provided with a first turned edge. The transparent shade comprises a second open end. The reflector is contained in the transparent shade. The first turned edge is fixedly connected to the second open end. The transparent shade and the outer wall of the reflector jointly enclose a light source cavity. Each LED light source comprises LEDs and a substrate. The substrates are disposed on the outer wall of the reflector at intervals. One end of every substrate is fixed to the outer periphery of the small end; the other end of every substrate extends to the large end; the surface, attached to the substrates, of the outer wall of the reflector is a plane; the surface, between each two adjacent substrates, of the outer wall of the reflector is an arc surface projecting out. The LED illumination lamp is high in utilization rate of optical energy and low in loss.

Description

technical field [0001] The invention relates to lighting technology, in particular to an LED lighting fixture. Background technique [0002] At present, with the maturity of LED chips and packaging technology, the brightness requirements of LEDs are sufficient to meet the needs of various lighting fields, and LED solid-state lighting has become a trend. It has performance characteristics such as energy saving, environmental protection, safety, high color rendering index, and long life; at the same time, it also has remarkable characteristics such as small size, high luminous efficiency, and low energy consumption. With its obvious advantages, LED light sources are widely used in scientific research experiments, production, and various fields of life, such as roads, tunnels, landscapes, indoor homes, commercial advertisements, industrial manufacturing and other lighting applications. [0003] Unlike incandescent lamps, metal halide lamps and other traditional light sources t...
