Description
Technical field
The present invention relates to a kind of LED, be particularly a kind ofly built-in with the LED of LED chip as light source.
Background technology
Recently, replace the incandescent lamp that power consumption is large, the employing LED little to power consumption is increasing as the demand of the LED of light source.
Usually, this kind of LED has: the metallic heat dissipating parts such as aluminium, and its heat conductivity is excellent; Lamp holder, it is arranged on one end of radiator, lampshade, and it is made up of the glass of printing opacity or plastic material, and have hemispheric top, and be arranged on the other end of radiator, module board, it is provided with LED chip, lighting circuit, and it is powered to LED chip; Further, this kind of LED also has following structure: module board and lighting circuit are arranged on radiator, and LED chip is covered by lampshade, lighting circuit and lamp holder electrical connection.
The light that the light source of incandescent lamp and filament send spreads towards periphery, irradiates around equably, and has following characteristic as the light that the LED chip that the light source of LED uses sends, that is, have high directivity, and penetrate narrow region, front with very strong illumination.In addition, the filament of incandescent lamp often reaches the high temperature of 2000 degree when lighting, and the surface covering the Lamp cup of filament is in high temperature by heating, if thus touch Lamp cup, have the danger be burned.
In contrast, extremely low compared with the light source of LED and the LED chip caloric value when lighting and the filament caloric value when lighting.Therefore have following characteristic: when lighting, even radiator, its temperature also only rises to tens of degree left and right, can be used in touching radiator.
But after long usage, the cover that waits of LED equally also can produce heat due to the Continuous irradiation of light, touches lampshade and also has burning sensation.And; current LED relies on step outside Lamp cup to realize the connection of Lamp cup and lampshade; illegally when connecting is formed with Lamp cup integrally; the structure comparison connected is loose; lampshade easily drops, and loses original guiding and protective effect, and inner LED luminous plaque is exposed in atmosphere; bring potential safety hazard, What is more can cause injury accident.
And, in time connecting the cable malfunction of aluminium base and LED drive circuit, likely will produce the phenomenon of electric leakage, can the critical safety to user.
Summary of the invention
The object of the present invention is to provide and be a kind ofly convenient to take, dispel the heat fast and lampshade and Lamp cup are connected firmly, safe LED.
For solving the problems of the technologies described above, LED of the present invention, comprising: aluminium alloy Lamp cup, in described aluminium alloy Lamp cup, be provided with cavity boss, described cavity boss and described aluminium alloy Lamp cup design for integral type, are connected with PC light guide lampshade at the opening part of described aluminium alloy Lamp cup; Lamp cup connector, described Lamp cup connector is arranged on outside described aluminium alloy Lamp cup, and described Lamp cup connector and described cavity boss form a material-putting space; Lamp holder, described lamp holder is by being connected with the on-fixed section of described Lamp cup connector; LED driver, described LED driver is arranged in described material-putting space; And aluminium base, described aluminium base is fixed by screw and described cavity boss, and described aluminium base is integrated with LED, and electric wire connects described aluminium base and described LED driver through the through wires hole on described cavity boss.
Preferably, be provided with shoulder pad at described aluminium alloy Lamp cup opening part inner ring, between described aluminium alloy Lamp cup and described PC light guide lampshade, be provided with flexible steel ring.
Preferably, described PC light guide lampshade comprises lamp shade body and is arranged on the extension of described lamp shade body inner ring, and the mounting structure that the mounting structure that described extension and described lamp shade body are formed and described aluminium alloy Lamp cup and described shoulder pad are formed agrees with.
Preferably, described Lamp cup connector comprises: insertion section; Connecting portion, one end of described connecting portion is connected with one end of described insertion section, is provided with screw thread in other one end of described connecting portion; And cover body, described cover body ring is located at the outside of insertion section, covers the tail end of described aluminium alloy Lamp cup.
Preferably, described cover body designs for cone.
Preferably, the contact surface of described aluminium base and described cavity boss is provided with heat-conducting medium.
Preferably, described heat-conducting medium is heat conductive silica gel or potsherd.
Cavity boss in LED aluminium alloy Lamp cup of the present invention can be linked and packed into whole lamp together with aluminium base, Lamp cup connector.The characteristic of flexible steel ring is combined with rim of a cup and forms rim of a cup step, then when adding PC light guide lampshade, can carry out gummed and fix.Aluminium alloy Lamp cup adopts narrow and small convex-concave thin-wall configuration spatial design, and after cavity boss is combined with aluminium base, area of dissipation is large, and heat-transfer rate is fast, leaves large space and place LED driver in its cavity.Potsherd, as pad, can play the function preventing electric leakage, protection user while reaching radiating effect.Aluminium alloy Lamp cup selects thin aluminium material, adopts special manufacturing process, as punching press and spinning drawing and forming.With other like product aluminium alloy die casts, heat-conducting plastic+aluminum component, ceramic post sintering etc. are shaping compares, and its advantage is that heat conduction and heat radiation speed is fast, and long service life is cheap for manufacturing cost.The present invention is used for series lamps such as LED-handkerchief (PAR) lamp and shot-light etc.
