Abstract

The utility model discloses an improved light-emitting diode (LED) daylight lamp structure, which comprises a light-transmitting shade, a heat dissipation base and an LED lamp group, wherein the heat dissipation base comprises a tube body and a supporting portion, and the LED lamp group is installed on the supporting portion. Two side edges of the light-transmitting shade are respectively provided with a connecting portion which is extended and bent downwards, the heat dissipation base is provided with protruding eaves, and the light-transmitting shade and the heat dissipation base are combined together by the matching between the protruding eaves and the connecting portions. The connecting portions are hooks portions which are extended downwards and bent inwards or outwards from two side edges of the light-transmitting shade, and the corresponding protruding eaves are outer eaves arranged on two side walls of the supporting portion or inner eaves arranged on two side edges of the tube body. The improved LED daylight lamp structure abandons a blocking wall on the supporting portion of a traditional LED lamp and does not block the light-transmitting shade, so light emitted by the LED lamp group can cover the whole light-transmitting shade, and the illumination range is wider.

Description

The LED fluorescent structure of improvement

Technical field

The utility model relates to lighting technical field, refers in particular to a kind of LED fluorescent structure of improvement.

Background technology

The LED lamp is a kind of semiconductor that electric energy can be converted into visible light, it has the efficient height, photochromic pure, light quality height, energy consumption is little, life-span is long, advantages such as illuminator points of proximity light source, and operating voltage is low, emission response time is extremely short, operating temperature range is wide, sound construction, series of characteristics such as stable and reliable for performance, extremely people's favor, and green illumination is the ecological design object that follow in the whole world, and LED is as a kind of energy-efficient light source, need not fill mercury, can reduce energy resource consumption and reduce greenhouse gases and other pollutants that in atmosphere, discharges, also LED and solar cell combination can be used, so, it is one of light source of environmental protection, is the novel green light source of 21 century of generally acknowledging in the world.

Common LED fluorescent lamp as depicted in figs. 1 and 2, include diffuser 10, radiating seat 20 and LED lamp group 30, this radiating seat 20 includes body 21 and

support portion

A kind of LED fluorescent structure of improvement, it includes diffuser, radiating seat and LED lamp group, this radiating seat includes body and support portion, LED lamp group is installed on this support portion, these diffuser both sides along on be respectively arranged with the downward crooked connecting portion that extends, this radiating seat is provided with protruding eaves, and diffuser is in the same place by the cooperation winding of connecting portion and protruding eaves with radiating seat.

Preferably, described support portion is provided with spacing draw-in groove, and above-mentioned LED lamp group is installed in this spacing draw-in groove.

Preferably, described LED lamp group is concordant with above-mentioned connecting portion, or is positioned at the connecting portion below.

Preferably, described connecting portion is to be extended and aduncate hook portion along downward by the diffuser both sides, and this protruding eaves is the outer eaves that is arranged on the two side, support portion.

Preferably, described connecting portion is to be extended and bandy hook portion along downward by the diffuser both sides, and this protruding eaves is to be arranged at the body both sides along last interior eaves.

Preferably, described LED lamp group is made up of LED wiring board and setting some LED unit thereon.

The utility model compared with prior art has tangible advantage and beneficial effect, particularly, as shown from the above technical solution, it mainly is to extend crooked connecting portion downwards and be connected with radiating seat by being arranged at the diffuser both sides, this kind syndeton has been removed the retaining wall on the support portion of traditional LED lamp, diffuser is not had any blocking, thereby the light that LED lamp group is sent can cover whole diffuser, illumination zone is wider.In addition, after diffuser and the radiating seat combination, support zone can make the illumination zone of LED lamp group wider in the below, junction of diffuser and radiating seat, and effect is better.By this, this structure has the effect with illumination zone expansion, thereby, make full use of light source, reach purpose of energy saving.

For more clearly setting forth architectural feature of the present utility model and effect, come the utility model is elaborated below in conjunction with accompanying drawing and specific embodiment.
