Description
Technical field
The utility model relates to a kind of LED, particularly relates to a kind of LED bulb being applied to warning lamp, and this LED bulb is for realizing a luminescence.
Background technology
Light fixture can be divided into lighting and warning lamp according to the different requirements of light source, and lighting requires that uniform illumination is dispersed usually, not dazzling.Warning lamp is generally for specific environment, and required certain legal or specific alarm function, its light must be given prominence to dazzling.Light source strictly should be followed and meet as refraction, reflection, parabolic reflective, hyperbola reflection etc. optical principle requirement for this reason, makes final light beam be parallel or pencil irradiation.Existing incandescent lamp/Halogen lamp LED is applied on warning lamp must be aided with various reflective mirror, as parabola/elliptical glass reflector, to change light path, increase application surface light intensity, this just requires that light source should be close to spot light as far as possible and irradiate at hemisphere face or global face, can be placed in focus, to meet light path principle requirement.
In prior art, the bulb kind of LED warning lamp generally has incandescent lamp, Halogen lamp LED and LED, and LED light source is that face is luminous, and incandescent lamp, Halogen lamp LED have the light source of filamentray structure for some luminescence.Single led luminescence chip cannot realize a luminescence, within the scope of 180 ° of fields, there is serious illumination poor simultaneously, namely illumination uneven illumination in the field illumination range of 180 ° is even, and the extraordinary warning lamps such as LED warning lamp are a luminescence for the requirement of light source and the field luminance scope of illumination is 360 °.Existing LED, due to its structure, is not well positioned to meet the instructions for use of warning lamp.
In prior art, general normal employing LED is as lighting, and in order to the intensity of illumination of satisfied illumination, prior art is welded on pcb board by LED lamp bead, and polylith pcb board surrounds a polygon-prism.Generally the limit number of polygon-prism being increased as far as possible of prior art, so that more LED can be installed, conventional is hexagon, existing scheme can meet the intensity of illumination of illumination, realize multilayer multiaspect Multi-point luminous, namely defining can be used in throwing light on also can carry out the LED of warning lighting, but like this LED lamp structure is Multi-point luminous and Integral luminous point is comparatively large, and when being applied to warning lighting, its effect is unsatisfactory.After the quantity on polygon-prism limit increases simultaneously, the single setting of structure due to each PCB, overall pcb board structural instability can be caused, affect its anti shock and vibration performance, in order to solve the problem of anti shock and vibration performance, arrange buckle fixed cap in prior art by the PCB top in polygon-prism structure, each pcb board is fixed by this buckle fixed cap, but polygon-prism inside defines a relatively airtight space, is unfavorable for that it dispels the heat; To be the scheme of head it off in the patent application of 201210086012.1 be the patent No. arranges the holder fixing with lamp socket in the bottom of PCB, holder and pcb board arranges connecting hole respectively and both are by screw fastening, and its structure is too complicated.
Utility model content
The utility model object is to provide a kind of LED bulb being applied to warning lamp, for solving LED light source in prior art, can not to form less point luminous with the problem of the various warning light distribution structure of adaptation, simultaneously of the present utility modelly can provide good anti shock and vibration performance and better radiating effect.
For above problem, provide following technical scheme: a kind of LED bulb being applied to warning lamp, comprise lamp socket and multiple LED component, it is characterized in that: described LED component comprises the pcb board being provided with single led lamp pearl, the bottom interference of described pcb board is plugged on lamp socket, and lamp socket arranges the inserting groove corresponding with bottom pcb board; Described LED component is three and the pcb board of its correspondence Formation cross-section on lamp socket is leg-of-mutton prism cavity, and the top of prism cavity is opened wide and arranged; Each described LED lamp bead is positioned at the centre position of corresponding pcb board width and is in phase co-altitude, and LED bulb includes the lamp holder of lens arrangement or adopts COB lamp pearl.
Adopt said structure, the pcb board interference of three LED component is plugged on lamp socket and defines prism cavity, realizes closely cooperating of pcb board and lamp socket, structurally has better stability, closely cooperate and can reduce thermal resistance on the other hand, improve radiating efficiency; Prism cavity open top arranges and this space can be made to communicate with lampshade structure when using, and can be convenient to heat exchange to realize high efficiency and heat radiation further; When the cross section of prism cavity is triangle, three LED lamp bead are arranged on corresponding pcb board respectively, relative to same circumference area and cross section hexagon, the volume of prism cavity is relatively little, under meeting the prerequisite of 360 ° of field luminance scopes, the field range section of two simultaneously adjacent LED lamp bead overlaps for making up the uneven illumination even problem of single led lamp pearl within the scope of 180 ° of fields, the setting of three LED lamp bead is comparatively concentrated, a luminous light-emitting area can be reduced as best one can, to be adapted to various warning light distribution structure; Adopt the lamp holder with lens effect or COB lamp pearl that illumination can be made more concentrated and even simultaneously.
The utility model is also set to further, described LED lamp bead is GaN base LED and comprises GaN semiconductor chip, insulating base and heat conducting base, heat conducting base is positioned at the bottom of insulating base, and described heat conducting base is close to pcb board and is filled heat-conducting silicone grease between the two.
Adopt said structure, make to realize high heat transfer between LED lamp bead and pcb board, improve radiating efficiency further.
