Abstract

The utility model discloses an LED lamp bulb. The LED lamp bulb comprises a lamp cap, a metal shell and a transparent cover. One end of the metal shell is connected with the transparent cover, and the other end of the metal shell is connected with the lamp cap. The lamp bulb is also provided with a connection board which is disposed at the connection part of the metal shell and the transparent cover and is connected and fixed with the metal shell. The transparent cover is connected with the connection board through a buckle to form a detachable spherical lamp bulb. The shell is provided with a radiating fin which can radiate the heat generated by the LED lamp bulb, and simultaneously luminescent efficiency is improved and service life is prolonged. The circuit board is ensured to be fixed and not to be shaken by disposing the circuit board in a cavity to the circuit board. The transparent cover is connected by the buckle, so that the LED lamp bulb is very convenient to disassemble and assemble, and the appearance can be beautiful.

Description

A kind of LED bulb

Technical field

The utility model relates to lighting field, is specifically related to a kind of LED bulb.

Background technology

In the daily life, illumination the most often contact is that light source has old-fashioned bulb, quartz bulb, fluorescent bulb, mercury vapor lamp etc.; Wherein, except that fluorescent lamp, most conventional lamp all is directly to be screwed onto the female seat of bulb to go up and use, be with, most family all will be provided with the female seat of traditional internal screw thread formula bulb in total together place, is screwed into use for the form bulb.

Existing illuminating lamp mainly by fluorescent lamp, electricity-saving lamp as working flare, the illuminating effect of fluorescent lamp can, but energy-saving effect is limited; Though electricity-saving lamp has energy-saving effect; But also will further improve its illumination effect, the LED bulb is with respect to traditional bulb, and its caloric value is big; Can directly have influence on the illumination effect of bulb, also influence the service life of LED bulb.

LED (light emitting diode) has advantages such as power saving, luminous efficiency is high, volume is little, and existing back LED lamp also is used on the advertisement billboard how as the display lamp usefulness in the circuit, and on the red signal lamp used by rail workers of the crosswalk of traffic signal light.

The utility model content

The problem that the utility model will solve provides a kind of LED bulb that high efficiency heat radiation is arranged, and prolongs the service life of LED bulb, has improved the illumination effect of LED bulb simultaneously.

For addressing the above problem, the utility model is realized through following scheme: a kind of LED bulb, and this LED bulb comprises lamp holder, metal-back, translucent cover; Said metal-back one end connects translucent cover; The other end connects lamp holder, also is provided with connecting plate on this LED bulb, and this connecting plate is arranged on metal-back and translucent cover junction; And be fastened on the metal-back, translucent cover connects to live connecting plate through buckle and forms removable orbicule bulb.

On the said connecting plate metal substrate is set, this metal substrate is fixed on the connecting plate through screw.

Said metal-back is provided with fin, the inner cavity that forms of said metal-back and fin, and this cavity is provided with circuit board and fixes.

Be with the termination on the said lamp holder, be rotatably connected through coupled threads between this lamp holder and the termination.

The beneficial effect of the utility model is: its shell is provided with fin, and the heat that can in time the LED bulb be sent dispels the heat away, improves luminous efficiency simultaneously; Increase the service life; Circuit board is arranged in the cavity, has guaranteed that the fixing of circuit board do not shake, and translucent cover connects through buckle; Dismounting is got up very convenient, makes good looking appearance equally.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model structure cutaway view;

Fig. 3 is the utility model structure explosive view.

Among the figure: 1, lamp holder, 2, fin, 3, connecting plate, 4, translucent cover, 5, the termination, 6, metal-back, 7, metal substrate, 8, screw, 9, circuit board.

The specific embodiment

The required conditions of tool commercial lighting all to the utmost such as the brightness of current LED, life-span, reliability, cost; And have power saving, with the little characteristic of volume; It is the bulb of light source with LED that the applicant grinds wound a kind of; It can directly screw togather use with the female seat of traditional bulb, and LED is applied on the ligthing paraphernalia, does detailed explanation again through embodiment and accompanying drawing.

Like Fig. 2, shown in Figure 3, the LED bulb comprises lamp holder 1, metal-back 6, translucent cover 4, and metal-back 6 one ends connect translucent cover 4; The other end connects lamp holder 1, and connecting plate 3 is arranged on metal-back 6 and translucent cover 4 junctions, and is fastened on the metal-back 6; Translucent cover 4 connects to live connecting plate 3 through buckle and forms removable orbicule bulb, and metal substrate 7 is set on the connecting plate 3, and metal substrate 7 is fixed on the connecting plate 3 through screw 8; Metal-back 6 is provided with fin 2, metal-back 6 and the fin 2 inner cavitys that form, and it is fixing that this cavity is provided with circuit board 9; Be with termination 5 on the lamp holder 1, be rotatably connected through coupled threads between lamp holder 1 and the termination 5.

As shown in Figure 1, connect power supply to termination 5 through knob, the work of LED bulb, the fin 2 heat radiation heats that bulb produced improve luminous efficiency, increase the service life.

When the LED lamp pearl in the bulb damages, can take off translucent cover 4, change the LED lamp pearl damaged and get final product, again translucent cover 4 is fastened connection through buckle, it is very convenient that maintenance and installation is got up.

This use New LED bulb; It mainly can be used in LED on the ligthing paraphernalia, and goes up the bulb that uses for the female seat of a kind of traditional bulb that can directly assemble, makes it and can directly be used by the consumer; The utility model can be to change the mode of formula LED; Make bulb keep normal operation, to reduce maintenance cost, the service life of improving bulb.
