A kind of LED light source module and LED light source thereof

Abstract

The embodiment of the invention discloses an LED (light emitting diode) light source module and an LED light source thereof. The LED light source comprises an LED enclosed single lamp, a side wall ring and a reflection device, wherein the LED enclosed single lamp consists of an enclosed support, a luminescent chip, a fluorescent adhesive and a light distribution lens, and the luminescent chip, the fluorescent adhesive and the light distribution lens are fixedly arranged on the enclosed support; the side wall ring is arranged on the periphery of the LED enclosed single lamp, the bottom of the reflection device is fixed together with the LED enclosed single lamp, and the C0-180 cross section and the C90-270 cross section of the reflection device are respectively coincided with the C0-180 cross section and the C90-270 cross section of the light distribution lens; and the C0-180 cross section profile of the reflection device is of a symmetrical shape, the C90-270 cross section profile of the reflection device is of a non-symmetrical shape, and the zenith height of the C0-180 cross section profile of the reflection device is less than that of the C90-270 cross section profile. In the application of street illumination, the LED light source module and the LED light source thereof particularly aim at the illumination of driveways, and the availability of illuminant light quantity is increased by 5-10 percent; and in the application of light cast illumination in a large area, the gradual change transition from the area below a lamp post to a periphery area is realized, so that an obvious dark field and a bright spot in an illuminant area are enabled not to occur, and the LED light source module and the LED light source thereof have the advantages of simple process and lower cost.

Description

technical field [0001] The invention relates to the technical field of LED lighting fixture manufacturing, in particular to an LED light source module and its LED light source. Background technique [0002] LEDs are easy to achieve various forms of light distribution. At present, the commonly used technical means is to design light distribution through lenses. Among them, the light distribution basis of LED lamps can be a primary light distribution process or a secondary light distribution process. [0003] The primary light distribution process is to package the lens on the packaging bracket during the process of packaging a single LED, so that it is integrated with the LED light-emitting chip, fluorescent glue and packaging bracket to form an LED optical system. Among them, the surface of the LED light-emitting chip is coated with fluorescent glue, which is the light source; the lens is generally a silicone lens. This process is equivalent to achieving the target light di...

Problems solved by technology

[0005] However, in the prior art, when the lamps using the primary light distribution process are used for lighting, the utilization rate of luminous flux is low; when the lamps using the secondary light distribution process are used for lighting, although the utilization of luminous flux has increased, the cost Higher, and the complexity of production operations is also greater
