Abstract

The utility model discloses an LED lamp, comprising an LED, a lens and a mounting base for positioning the lens and the LED; the lens comprises a light pipe for guiding the light emitted by the LED to the top and a light splitting base for dispersing the light to each part; one end of the light pipe is connected with the mounting base, and the other end of the light pipe is connected with the light splitting base. The structure of the lamp uses the reflection and refraction principle of lens to light, and the lamp can realize luminous effect of LED within the range of total space, thereby replacing the traditional light source with high power consumption and short service life.

Description

A kind of LED light fixture

Technical field

The utility model relates to lighting, is meant a kind of LED light fixture that utilizes lens arrangement to reach special illumination effect especially.

Background technology

Along with going deep into of environmental protection and energy saving idea, the LED lamp is low owing to energy consumption, brightness is high is widely used, and its energy-conserving and environment-protective, long service life are about 1/10 of incandescent lamp as the energy consumption of white light LEDs, be 1/4 of electricity-saving lamp, and the life-span can reach 100,000 hours; Yet, because LED lamp luminous inhomogeneities on all directions, and its lighting angle has certain directionality, can be luminous in the total space (4 π solid angle) scope unlike incandescent lamp etc., therefore be restricted in some special application fields, thereby can't replace traditional light source fully, as in fields such as Crystal lamp, candle-type lamps, the LED lamp just can't directly substitute conventional light source, and the light beam that needs earlier the LED lamp to be sent carries out the shaping processing, just can reach the equal effect of conventional light source, limit its range of application.

In view of this, the design people's emphasis is studied the shaping processing that the LED lamp sends light beam, by optic total reflection principle, develops a kind of lighting that utilizes lens arrangement can change the lighting effect of LED lamp.

The utility model content

Main purpose of the present utility model is to provide a kind of LED light fixture, and it can realize LED luminous effect in full extent of space, replaces short conventional light source of power consumption height, service life.

In order to reach above-mentioned purpose, solution of the present utility model is:

A kind of LED light fixture, comprise LED, lens and be used for positioning lens and the mounting base of LED, lens comprise that the light that LED is sent leads the light pipe on top and light is distributed to the beam split seat of each several part, and an end of light pipe is connected with mounting base, and the other end connects the beam split seat.

Above-mentioned mounting base comprises a pedestal and two card bases, and the center of pedestal has through hole, and both sides extend to form boss downwards, and two card bases are separately fixed on the boss of both sides.

Above-mentioned boss is round table-like or circular.

In the middle of serving as reasons, above-mentioned light pipe, and is provided with the dome-type containing cavity in the bottom to the column structure of two ends convergent.

Above-mentioned light pipe is the column structure of bottom convergent, and the contraction flow region of bottom forms the dome-type containing cavity.

Above-mentioned beam split seat is a frustum cone structure, and forms arc groove in this round platform.

Above-mentioned LED is single led light source or adopting surface mounted LED array.

After adopting such scheme, the utility model is by the special lens arrangement of design, at first LED is fixed on the mounting base of lens bottom, by light pipe the light that LED sends is all led lens distal end, utilize of reflection and the refraction of beam split seat then, the part in the light is seen through by the top, realize the luminous of lens upper half-space light, and make other a part of light shine the latter half of lens, thereby realize LED luminous effect in full extent of space.

The specific embodiment

Below in conjunction with drawings and the specific embodiments enforcement structure of the present utility model and beneficial effect are elaborated.

Referring to figs. 1 to shown in Figure 3, be the preferable enforcement structure of a kind of LED light fixture provided by the utility model, it comprises LED 4, mounting base 1 and lens, and wherein lens comprise light pipe 2 and beam split seat 3.

Mounting base 1 is positioned at bottommost, be used for fixing the LED structure that connects various kenels, the structure of this mounting base 1 also can be varied, as in the present embodiment, mounting base 1 comprises pedestal 11 and card base 12, and card base 12 is used for positioning lens, and realize being connected of lens and LED 4, the center of pedestal 11 has through hole 113, and extends to form round table-like boss 111, two card bases 12 downwards in both sides and promptly be separately fixed on this boss 111.

Light pipe 2 is middle columnar shape to the two ends convergent, and its bottom is formed with the containing cavity 21 of dome-type, is used for ccontaining LED, and light is reflected or reflects processing, and this containing cavity 21 is corresponding with the through hole 113 of mounting base 1, and is fixed on the mounting base 1.。

Beam split seat 3 is a frustum cone structure, and it has opening arc groove 31 up, and with reference to shown in Figure 3, beam split seat 3 is a form wide at the top and narrow at the bottom among this embodiment.

The employed LED 4 of present embodiment, it both can be single LED (as single high-power or low-power LED) light source, it also can be the array that forms by a plurality of LED (as the small-power adopting surface mounted LED), as shown in Figure 6, in this embodiment, adopt single led light source, it comprises led light source 41 (as shown in Figure 4) and aluminium base 42 (as shown in Figure 5); During assembling, at first that led light source 41 and aluminium base 42 welding is fixing, be fixed on then on the mounting base 1, and the location of realizing lens by the card base on the mounting base 1 12, fixing, the light that led light source 41 sends is invested light pipe 2, by reflection of light and refraction principle, light pipe 2 is all led the top with the light that led light source 41 sends, and is handled by 3 pairs of light of beam split seat then, and the part in the light is seen through by the top, realize the luminous of upper half-space, and make other a part of light shine the latter half, thus realize LED luminous effect in full extent of space, thus the use of conventional light source can be replaced, reduce power consumption, improve brightness of illumination.
