Background

The structure adopted in the conventional automobile lamp, searchlight and illumination lamp, as shown in fig. 1, mainly comprises an LED lamp 4 and a reflector, wherein the reflector adopts a parabolic structure, the parabolic structure is a parabolic mirror formed by rotating a parabola 360 degrees along a central shaft, the LED lamp 4 is installed on the focus of the central shaft, and the head of the LED lamp 4 faces the opening of the reflector. When the LED lamp 4 emits light, since the LED lamp 4 is installed at the focal point, the light emitted from the LED lamp 4 is reflected by the parabolic mirror and then emitted, and the emitted light is parallel to the central axis.

Adopt this kind of mode to have following problem, firstly, because the luminous intensity distribution of LED lamp 4 does, perpendicular to center pin light luminous intensity is the highest, and the contained angle of light and center pin is big more, then the light intensity is weaker. Therefore, the light emitted from the LED lamp 4 is the light with the strongest light intensity within the angle of 0-30 degrees with the central axis, but since the light within the angle range cannot be irradiated on the parabolic mirror surface, the light is directly irradiated out and wasted as stray light. The LED can irradiate the parabolic mirror, and the included angle between the light rays reflected by the parabolic mirror and the central axis is certainly larger than 60 degrees, so that the intensity of the light of the part is not high, and the irradiation distance of the light rays reflected by the parabolic mirror is not long.

In order to solve the problems, a novel LED illuminating lamp is provided.
