Technical Field

The invention relates to the technical field of illumination, in particular to an outdoor illumination lamp body.

Background

Outdoor environment has certain unknown nature, therefore outdoor lighting device requires to be higher than indoor lighting device far away, and current outdoor lamps and lanterns all are provided with distance light and short-distance beam function generally, because distance light and short-distance beam all send through the same light source (generally for the LED light source), consequently can have following technical problem:

1. the light source is controlled to emit light by using the same power, so that the outer ring has a large dark area when the light source is adjusted to be in a near light mode;

2. the light sources are controlled to emit light by using different powers, so that the service life of the light sources is influenced due to large fluctuation of the working power of the light sources.

Disclosure of Invention

The invention aims to provide an outdoor illuminating lamp body, which solves the problems.

The technical scheme of the invention is as follows: the utility model provides an outdoor illuminating lamp body, includes lamp stand, back lamp shade, lens, preceding lamp shade and light source, back lamp shade and preceding lamp shade threaded connection, lens are located between back lamp shade and the preceding lamp shade, are fixed in the preceding lamp covers, be close to on the back lamp shade the one end of preceding lamp shade is provided with annular cover the longitudinal section of annular cover is the arc, the central point of back lamp shade puts and is provided with first light source, the annular covers with first light source is provided with the second light source for central circumference, the rated power of second light source is less than the rated power of first light source.

The outdoor illuminating lamp body provided by the invention can control the first light source to be used as a light source independently, and also can control the first light source and the second light source to be used simultaneously, particularly when the outdoor illuminating lamp body is matched with a lens for use, the first light source is used as a high beam light source, emitted light is condensed through the center of the lens, the second light source is used as a low beam light source, and the emitted light is emitted through the edge position of the lens.

Preferably, the lens is a convex lens, and the convex lens structure is matched with the annular cover and the rear lamp cover structure to achieve a good illumination effect.

Preferably, the light source is an LED lamp bead, so that the light source is energy-saving, long in service time and used in outdoor service environment.

Preferably, the arc-shaped opening of the annular cover faces the front lamp cover, so that the light emitted by the second light source is concentrated at the central position of the convex lens, the high beam mode can be assisted, and the illumination range of the high beam mode is enlarged.

Preferably, the arc opening of annular cover dorsad the headlight cover, like this, the light that the second light source sent shines through convex lens again through diffuse reflection, is applicable to the occasion that the short-distance beam mode required is higher.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

Referring to fig. 1 and 2, the invention provides an outdoor illuminating lamp body, which comprises a lamp holder 11, a rear lamp cover 12, a lens 13, a front lamp cover 14 and a light source, wherein the rear lamp cover is in threaded connection with the front lamp cover, the lens is positioned between the rear lamp cover and the front lamp cover and is fixed on the front lamp cover, one end of the rear lamp cover, which is close to the front lamp cover, is provided with an annular cover 15, the longitudinal section of the annular cover is arc-shaped, the central position of the rear lamp cover is provided with a first light source 16, the annular cover is circumferentially provided with a second light source 17 by taking the first light source as a center, and the rated power of the second light source is smaller than the rated power of the first light source. The lens is preferably a convex lens, and the light source is preferably an LED lamp bead.

When the outdoor illuminating lamp body is used, the first light source can be controlled to be used as the light source independently, the first light source and the second light source can also be controlled to be used simultaneously, particularly when the outdoor illuminating lamp body is matched with the convex lens for use, the first light source is used as a high beam light source, emitted light is condensed through the center of the lens, the second light source is used as a low beam light, and the emitted light is emitted through the edge position of the lens.

In this embodiment, the annular cover may be provided in two forms:

form 1: referring to fig. 1, the arc-shaped opening of the annular cover faces the front lamp cover, so that the light emitted by the second light source is more concentrated at the central position of the convex lens, and the high beam mode can be assisted, and the illumination range of the high beam mode is enlarged.

Form 2: referring to fig. 2, the arc-shaped opening of the annular cover faces away from the headlight cover, so that light emitted by the second light source is diffused and then irradiated by the convex lens, and the annular cover is suitable for occasions with high requirements on low beam modes.

It should be noted that the above-mentioned embodiments are merely illustrative and not restrictive, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention, and such changes and modifications should be covered by the protection scope of the invention.
