Description

A kind of high-heat-dispersion LED bulb

Technical field

The utility model relates to the LED lighting, is specifically related to the LED bulb structure.

Background technology

Mention illumination, people can expect those motley various light fixtures in the lamp store at once.Although coming in every shape of these light fixtures, the core of its illumination--bulb mainly contain three kinds in fact: incandescent lamp and fluorescent lamp, gas-discharge lamp.But, this general layout will change soon because lighting field a nova--light emitting diode bulb is moving towards the practicability stage.

LED (Light Emitting Diode, light emitting diode) is a kind of solid-state semiconductor devices that can electric energy be converted into visible light, and it can directly be converted into light to electricity.Because the advantage of LED lighting engineering has been developed the novel light-emitting diode bulb that is used to throw light on recently.This bulb has efficient height, long characteristics of life-span, can use continuously 100,000 hours, than long 100 times of ordinary incandescent lamp bubble.In the coming years, this LED bulb becomes the main product of illumination of future generation probably.

Existing LED bulb is that profile is similar to incandescent light bulb, but its structure is different fully, generally is to adopt following structure: include the screw socket of light bulb base or the lamp socket of bayonet socket; Be arranged at the LED power supply circuit board in the lamp socket; Socket fixed heat sink on the lamp socket is placed a LED lamp plate on the radiator, the LED lamp plate generally adopts a plurality of LED that distribute on the circular substrate to form; The top that lies against radiator is then fixed; The fixing back of lampshade socket that the lampshade of the fixing dome-type of socket again on the radiator then, radiator generally are made into the latter half and the dome-type of globular bulb forms the profile of incandescent light bulb.

The weak point that existing this LED bulb structure exists is: the heat dispersion of radiator is efficient inadequately.

The utility model content

The utility model technical problem to be solved is; Overcome the not good defective of heat dispersion of existing LED bulb heat radiation device, a kind of improved LED bulb structure is provided, can realize better thermal diffusivity; Profile is also more attractive in appearance simultaneously, and the LED bulb is also more safe and reliable.

In order to solve the problems of the technologies described above, the utility model adopts following concrete technical scheme:

A kind of high-heat-dispersion LED bulb; Comprise the light bulb base lamp socket is set, be provided with the LED power supply circuit board in the lamp socket, the radiator of a tubular of socket on the lamp socket; Lamp socket upper end is fixed with the LED lamp plate and is connected in the LED power supply circuit board in the lamp socket through lead, fixing lampshade of socket again on the radiator.Wherein, described radiator is reined in by 1 radiating cylinder body and a plurality of heat radiation and is formed, and to rein in be to be down " V " type in heat radiation, and a plurality of heat radiation is reined in and is connected with each other and around on the outer wall that is arranged at the radiator cylindrical shell, the space structure that lampshade is wrapped up in proper formation is reined in heat radiation.Like this, rein in lampshade is wrapped in wherein through falling the heat radiation of " V " type setting, can form guard space, broken even lampshade is clashed into, security is better.Simultaneously, because the heat radiation of " V " type is reined in, radiating effect is better.

Further, go back vertically a plurality of side by side heat sink strips at interval on the radiating cylinder body of described radiator.Through the setting of heat sink strip, can further increase heat dispersion.

Further, described lamp socket is made up of screw socket cover seat and the socket of lamp socket adapter sleeve, and screw socket cover seat screws on the screwed pipe that is socketed on lamp socket adapter sleeve lower end, lamp socket adapter sleeve upper end socket one cover plate, fixing described LED lamp plate on the cover plate.Through the structure of screw socket cover seat and lamp socket adapter sleeve socket composition lamp socket, not only install easily, also be beneficial to simultaneously the LED power supply circuit board in the lamp socket is changed maintenance.

Further; Described cover plate is provided with screw and wire through-hole; Also be provided with screw on the LED lamp plate, through screw with the LED lamp plate sealed fixing on the cover board, the lead that is connected on the LED lamp plate passes wire through-hole and is connected to the LED power supply circuit board in the lamp socket.The LED lamp plate is fixed and realized the electric connection of LED lamp plate and LED power supply circuit board through wire through-hole through screw, it is simple and reasonable.

The utility model adopts said structure; Compared with prior art can realize better heat dispersion; Simultaneously, the heat radiation on the radiator is reined in has protective effect to lampshade, and the LED bulb is safer on using; And the heat radiation rein in be down " V " type be arranged on the radiating cylinder body moulding also the ten minutes attractive in appearance, liked by the consumer.

Fig. 2 is the stereogram after each member of the utility model embodiment is assembled.

The specific embodiment

Combine the accompanying drawing and the specific embodiment that the utility model is further specified at present.

Consult illustrated in figures 1 and 2; The high-heat-dispersion LED bulb of the utility model; Comprise: the light bulb base lamp socket is set, and lamp socket can be screw socket or bayonet socket, and the lamp socket in the present embodiment adopts the screw socket structure; Be made up of with 2 sockets of lamp socket adapter sleeve screw socket cover seat 1, promptly screw socket cover seat 1 screws on the screwed pipe 21 that is socketed on lamp socket adapter sleeve 2 lower ends.Through the structure of screw socket cover seat 1 and lamp socket adapter sleeve 2 sockets composition lamp socket, not only install easily, also be beneficial to simultaneously the LED power supply circuit board 3 in the lamp socket is changed maintenance.Be provided with LED power supply circuit board 3 in the lamp socket, fixing radiator 4 of socket on the lamp socket, promptly the nozzle of radiator 4 lower ends is socketed on the urceolus 22 of lamp socket adapter sleeve 2 upper ends.Lamp socket adapter sleeve 2 upper end sockets one cover plate 5, fixed L ED lamp plate 6 on the cover plate 5.LED lamp plate 6 also is connected in the LED power supply circuit board 3 in the lamp socket through lead (scheming not shown).Concrete; Described cover plate 5 is provided with screw 51 and wire through-hole 52; Also be provided with screw 61 on the LED lamp plate 6, with LED lamp plate 6 sealed being fixed on the cover plate 5, the lead that is connected on the LED lamp plate 6 passes wire through-hole 52 and is connected to the LED power supply circuit board 3 in the lamp socket through screw 7.Fixing lampshade 8 of socket again on the radiator 4.Wherein, Described radiator 4 is reined in 41 by 1 radiating cylinder body 43 and a plurality of heat radiations and is formed; To rein in 41 be to be down " V " type in heat radiation, and a plurality of heat radiation is reined in 41 and is connected with each other and around on the outer wall that is arranged at radiator cylindrical shell 43, heat radiation is reined in 41 and just formed the space structures that wrap up lampshades.Like this, rein in 41 lampshade 8 is wrapped in wherein through falling the heat radiation of " V " type setting, can form guard space, broken even lampshade is clashed into, security is better.Simultaneously, because the heat radiation of " V " type is reined in, radiating effect is better.Preferred, go back vertically a plurality of side by side heat sink strips 42 at interval on the radiating cylinder body 43 of described radiator 4.Through the setting of heat sink strip 42, can further increase heat dispersion.
