Abstract

The utility model provides a high-brightness LED lamp which comprises a lamp cap and a lamp body. A transparent lampshade covers the outer portion of the lamp body, the lamp body comprises a circuit board, a power supply arranged on the back face of the circuit board and a plurality of LED chips arranged on the front face of the circuit board, the LED chips are arranged in the middle of the circuit board, an optical lens wraps the outer portions of the LED chips, a reflective plate is arranged on the outer side portion of the optical lens, a perpendicular incidence lens is arranged on the outer side of the reflective plate and on a reflective light path, and furthermore a Fresnel lens is arranged on the outer portion of the perpendicular incidence lens. The LED lamp is wide in irradiation range, high in brightness and good in luminescence property, and can be used as security lamps, fog lamps, traffic lights and indicator lights.

Description

High-brightness LED lamp

Technical field

The utility model relates to a kind of LED light fixture, and the LED lamp that especially a kind of irradiating angle is large, intensity of illumination is high, belong to the LED lighting technical field.

Background technology

LED is the abbreviation of light emitting diode, is a kind of solid matter that can convert electrical energy into luminous energy,, due to the advantage of its energy-conserving and environment-protective, replaces just gradually at present conventional light source, and a plurality of fields in productive life are widely used.

At present in order to increase the illuminating effect of LED light fixture, Most designers changes with quasi-parallel light by the central part mounted lens at LED, the light source of launching from central part is by after the plastic optics internal system, externally parabola turns reflection, break away from lamp optical system after same angle change with quasi-parallel, the product of this structure has only adopted single optics, simple in structure, when the light that Dang Cong sends at center changes with wide-angle, inefficiency, intensity of illumination is inadequate, can't apply and the place that needs floodlighting and occasion.

The utility model content

The utility model is namely the weak point that exists in above-mentioned LED light fixture, and the LED that a kind of range of exposures is wide, brightness is high light fixture is provided.

Specifically, high-brightness LED lamp described in the utility model, comprise lamp holder and lamp body, lamp body is covered with Transparent lamp shade, lamp body comprises circuit board, be arranged on the power supply of back of circuit board and be arranged on plurality of LEDs chip on the circuit board front, and LED chip is arranged in the middle part of circuit board, in the LED chip outside, is surrounded with optical lens, the side foreign side of optical lens is provided with reflecting plate, and the outside of reflecting plate is provided with the direct projection lens on reflected light path.

Further, be provided with Fresnel Lenses in the outside of described direct projection lens.

Fresnel Lenses (Fresnel lens), have another name called Fresnel lens, mostly be to annotate and press the thin slice that forms by polyolefine material, also there is glass to make, lens surface is simultaneously the light face, the another side imprinting ascending concentric circles, its texture is according to interference of light and disturb and penetrate and relative sensitivity and receiving angle require to design.The lens of a slice high-quality must any surface finish, clean mark, and its thickness becomes with purposes, and how in the 1mm left and right, characteristic is that area is large, thin thickness and detecting distance.Fresnel Lenses is equivalent to the convex lens of infrared ray and visible light many times, and effect is better, but cost is more much lower than common convex lens.

Further, the number of described Fresnel Lenses is two, be distributed in the both sides of direct projection lens outside, and position is relative.

Further, the number of described reflecting plate is more than two, is distributed in the side foreign side of optical lens, and evenly arranges centered by optical lens.

High-brightness LED lamp described in the utility model, simple and practical, play the effect of amplification light at the outside optical lens of installing of LED chip, again by reflecting plate with amplification light linearization(-sation), by optical lens and reflecting plate with the light expanded range, battle-sight range reaches more than 8 meters, and light is again through pinching the Fei Er lens, and light is stronger; Described LED light irradiation scope is wide, brightness is high, good luminous performance, can be used as security lamp, fog lamp, traffic lights and indicator lamp.

Description of drawings

Fig. 1 is the vertical section schematic diagram of the utility model embodiment;

Wherein, 1 is that lamp holder, 2 is that power supply, 3 is that circuit board, 4 is that LED chip, 5 is that optical lens, 6 is that reflecting plate, 7 is that direct projection lens, 8 are that Fresnel Lenses, 9 is lampshade.

The specific embodiment

Below in conjunction with accompanying drawing, LED lamp described in the utility model is carried out nonrestrictive description.

as shown in Figure 1, high-brightness LED lamp described in the utility model, comprise lamp holder 1 and lamp body, lamp body is covered with Transparent lamp shade 9, lamp body comprises circuit board 3, be arranged on the power supply 2 and the plurality of LEDs chip 4 that is arranged on circuit board 3 fronts at circuit board 3 back sides, LED chip 4 is arranged in the middle part of circuit board 3, be surrounded with optical lens 5 in LED chip 4 outsides, the side foreign side of optical lens 5 is provided with reflecting plate 6, the outside of reflecting plate 6 is provided with direct projection lens 7 on reflected light path, be provided with Fresnel Lenses 8 in the outside of described direct projection lens 7, the number of described Fresnel Lenses is two, be distributed in the both sides of direct projection lens outside, and position is relative, the number of described reflecting plate is more than two, be distributed in the side foreign side of optical lens, and evenly arrange centered by optical lens.

High-brightness LED lamp described in the utility model, simple and practical, range of exposures is wide, brightness is high, good luminous performance, and is of many uses.

It should be understood that top description is unrestricted, in fact, all improvement of described structure being carried out with identical or approximate principle, realize basic identical function, all within the utility model scope required for protection.
