Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a LED flood reflector and LED lamps with a sufficiently small size for the above-mentioned oversized defects of the LED reflectors in the prior art, so that the LED lamps can meet the illumination requirements. Under the circumstances, the volume should be as small as possible, and the light distribution effect with a rectangular irradiation range can be realized

Embodiment Construction

[0029] The invention provides a flood reflector, which is used for light distribution of LED light sources. The reflector satisfies flood lighting and at the same time greatly reduces the volume of the reflector, thereby saving space and making the structure of LED lamps more compact. , the volume is smaller, and at the same time, the reflector can also provide a light distribution with a rectangular irradiation range, which can make full use of the light emitted by the light source.

[0030] The reflector of the present invention has a bottom end and an open end. When used in conjunction with an LED light source, the LED light source is located at the bottom end of the reflector. Part of the light emitted by the LED light source is directly emitted from the open end, and the other part passes through the light reflecting surface of the reflector. After reflection, it exits through the open end.

[0031] The reflector includes four contiguous light reflecting surfaces, namely:...

Abstract

The invention relates to an LED (Light Emitting Diode) floodlight reflector and an LED light fitting, wherein the LED floodlight reflector comprises four connected light reflection surfaces, the shape of each light reflection surface is formed by stretching a broken line segment towards the two sides of the broken line segment along a direction vertical to the plane of the broken line segment, the stretching broken lines of opposite light reflection surfaces are identical, and the stretching broken lines of adjacent light reflection surfaces are different; and the LED light fitting comprises an LED light source and the LED floodlight reflector, the LED light source is arranged on the bottom end of the LED floodlight reflector, and the optical axis of the LED light source is overlapped with the axial line of the reflector. The light reflection surface in the invention is formed by stretching the broken line segment, so that the formed reflector can greatly reduce the volume of the reflector when meeting with the light distribution demand of floodlight illumination so as to reduce the volume of the LED light fitting, and the stretching broken lines of the adjacent light reflection surfaces are different to realize the light distribution effect within a rectangular illumination range.

Description

technical field [0001] The invention relates to the field of lighting lamps, and more specifically, to an LED flood reflector and an LED lamp. Background technique [0002] With the rapid development of high-power LED technology, more and more LEDs are used as light sources in the lighting field. When the LED light source is not reflected by the reflector or refracted by the lens, its luminous light distribution characteristics conform to the radiation law of the Lambert (J.H.Lambert) luminous body. This type of luminous body is also called a cosine luminous body. Its luminous intensity is dI and cosθ is positively correlated, that is, its brightness B has nothing to do with the direction, where dI is the luminous intensity of each surface element dS of the extended light surface along a certain direction r, and θ is the angle between r and the normal n. When the light emitted by the LED light source is not distributed, its illumination intensity is very uneven. In order to...
