The utility model discloses an LED (Light Emitting Diode) bulb lamp. The LED bulb lamp comprises a lamp holder, a top shell, a circuit board, a bottom shell and a lamp cover, wherein the lamp holder is in screwed connection with the top shell, the circuit board is fixedly arranged on the bottom shell, the lamp cover is connected with the bottom shell, the top shell is provided with a narrow-side ejecting structure, the narrow-side ejecting structure is provided with an acute angle structure, the periphery of the bottom shell is provided with a groove structure, a convex structure is arranged beside the groove structure, and the top end of the convex structure is provided with a convex end which is in fit with the acute angle structure. According to the LED bulb lamp disclosed by the utility model, strong impacting forces generated in assembling and disassembling processes of the top shell and the bottom shell can be successfully relieved by utilizing the acute angle structure and the convex end, the technical problem that the top shell and the bottom shell are broken due to manufacturing materials of the top shell and the bottom shell, the mechanical property and the like in the assembling and disassembling processes of the top shell and the bottom shell can be solved, unqualified products can be greatly reduced, and the cost of an enterprise can be reduced.
Description
Technical field
The utility model belongs to field of light fittings, is specifically related to a kind of LED bulb lamp.
Background technology
Filament energising is heated to incandescent state by incandescent lamp, utilizes heat radiation to send the electric light source of visible ray.From 1879, since T.A. Edison of the U.S. has made carbon fibre (being carbon filament) incandescent lamp, through people, to the updating of filament material, filamentray structure, filling gas, the luminous efficiency of incandescent lamp is corresponding improve also.But along with scientific and technological development, in the lighting of all electricity consumptions, the efficiency of incandescent lamp is minimum.The electric energy that it consumes is only had an appointment and 2% can be converted into luminous energy, and remainder has has all scattered and disappeared with the form of heat energy.As for lighting hours, conventionally can not exceed 1000 hours the service life of this electric light.Along with various countries forbid the propelling of incandescent lamp and time gradually, it is a kind of inexorable trend of development that incandescent lamp steps down from the stage of history.
In numerous lightings, the optimal selection of replace incandescent is exactly LED lamp, LED lamp has utilized LED(Light Emitting Diode) structure and principle of luminosity, LED(light emitting diode), be a kind of solid-state semiconductor devices that can be visible ray by electric energy conversion, it can directly be converted into light electricity.The advantage of LED lamp maximum is exactly energy-conserving and environment-protective.More than the luminous efficiency of light reaches 100 lumens/watt, common incandescent lamp can only reach 40 lumens/watt, and electricity-saving lamp is also just hovered in 70 lumens/watt left and right.So, same wattage, LED lamp effect can be bright more a lot of than incandescent lamp and electricity-saving lamp.The brightness of 1 watt of LED lamp is equivalent to the electricity-saving lamp of 2 watts of left and right, and the power consumption 5 in 1000 hours of 5 watts of LED lamps is spent, and the LED lamp life-span can reach 50,000 hours, and LED lamp is radiationless.
In all LED lamps, LED bulb lamp is again the one of the most often using, and LED bulb lamp is made up of structures such as lamp holder, top shell, drain pan, circuit board, heat dissipating housing and lampshades mostly.In the interface mode of LED lamp, exist the mode such as screw socket and socket, in socket mode, in the eye-splice process of top shell and drain pan, often adopt straight cutting mode, but due to reasons such as the making material of top shell and drain pan (make material and be mostly plastics) and mechanics, in the process of the assembly and disassembly of being everlasting, cause breaking of top shell and drain pan.
In Chinese utility model patent description CN202674934U, disclose a kind of LED bulb lamp, if the lamp socket of described LED lamp and transparent lamp case utilize socket mode to combine, tended to cause breaking of lamp housing.
Utility model content
Existing in the eye-splice process of top shell and drain pan in order to solve, due to the reason such as making material and mechanics of top shell and drain pan, in the process of the assembly and disassembly of being everlasting, cause the technical problem of breaking of top shell and drain pan, the utility model provides a kind of LED bulb lamp.
Described a kind of LED bulb lamp, comprise lamp holder, top shell, circuit board, drain pan and lampshade, described lamp holder spiral connects top shell, described circuit board is fixed on described drain pan, and described lampshade connects described drain pan, and described top shell is provided with narrow limit ejecting structure, described narrow limit ejecting structure is provided with an acuter angles, the outer groove structure that is arranged with of described drain pan, described groove structure side is a bulge-structure, the top of described bulge-structure is provided with the protruding end agreeing with mutually with described acuter angles.
Preferably, between described circuit board and described drain pan, be provided with a thermal insulation board, by a screw structural fixing circuit board and thermal insulation board on drain pan.
For increasing heat radiation, preferably, between described drain pan and lampshade, be provided with a radiating subassembly, described radiating subassembly is fixed on drain pan by a bolt arrangement.
The utility model utilizes acuter angles and protruding end, successfully slowed down the powerful impulsive force producing in the process of top shell and drain pan assembly and disassembly, solve in the process of the assembly and disassembly of top shell and drain pan, due to the top shell that reason causes such as making material and mechanics of top shell and drain pan and the technical problem of breaking of drain pan, a large amount of minimizings defective work, reduced the cost of enterprise.
