Background technology
White light LEDs is since 1996 come out, volume is little, caloric value is low, power consumption is few owing to having, fast, the environmental protection of life-span long (more than 100,000 hours), reaction speed, there is not advantage such as light pollution, the light source of new generation of conventional light source such as becoming can replace incandescent, fluorescent lamp, high-pressure discharge lamp.
At present, white LED light source ball bubble adopts SMD more or arranges mode with the single cap lamp pearl of ф 5mm with the individual layer horizontal plane to be welded on aluminium base or the PCB wiring board, it is with the even cloth socket weldering of the single cap lamp pearl of tens of ф 5mm each concentric turns on PCB wiring board plane and is electrically connected, because the intensive slotting weldering of the single cap lamp pearl of LED, the phase mutual edge distance is too near, its plane of illumination must be subjected to mutual obstruct when bright when the single cap lamp pearl of LED is opened, thereby influences lighting effect.
Summary of the invention
The light diffusion pagoda shape white LED light source bulb that the purpose of this utility model is to provide a kind of can increase white LED lamp pearl ball bubble light-emitting area, improve light efficiency, illuminance is more even, comfortable, soft.
The technical solution that the utility model proposed is such:
A kind of light diffusion pagoda shape white LED light source bulb, comprise lamp holder, lamp body, spherical diffuser, the constant current constant voltage dc source, fixedly connected with lamp holder in the lamp body bottom, lamp body top and spherical diffuser are tightly connected, the lamp body inner chamber is equipped with the PCB wiring board, the constant current constant voltage dc source is contained in below the PCB wiring board, the constant current constant voltage dc source is electrically connected by lamp holder and external power, the PCB wiring board that is positioned at the lamp body inner chamber is rearranged by at least one annular PCB wiring board and the classification of a circular PCB wiring board, the internal diameter of the annular PCB of subordinate wiring board is equal to or greater than the external diameter of adjacent upper level annular PCB wiring board, the diameter that is positioned at the circular PCB wiring board of upper top is equal to or less than the internal diameter of adjacent annular PCB wiring board, vertical range between adjacent annular PCB wiring board or the circular PCB wiring board is equal to or slightly greater than the height of white LED lamp pearl, on the annulus of annular PCB wiring board, be covered with the white LED lamp pearl, a circle white LED lamp pearl is equipped with in circle PCB wiring board central authorities, a higher white LED lamp pearl is equipped with in its central authorities, 2-4 the insulation deck that radian is arranged such as also be provided with, each layer PCB wiring board horizontal card is connected on the insulation deck, become pagoda shape white LED lamp pearl assembly, each white LED lamp pearl is with string, parallel form and described constant current constant voltage dc source are electrically connected.
Circular PCB wiring board of 2-8 layer and annular PCB wiring board are housed in the described lamp body inner chamber.
Described insulation deck be provided with described bulb in the horizontal draw-in groove that is complementary of the PCB wiring board number of plies, this insulation deck is arranged in the central area of pagoda shape white LED lamp pearl assembly.
Compared with prior art, the utlity model has following beneficial effect:
1. white LED light source globular bulb in the market all is that neat intensive horizontal socket of white LED lamp pearl or level are pasted on the PCB wiring board, white light LEDs ball bubble opens when bright each lamp pearl top light and shows up and obtain full use, but the effect of each lamp pearl ambient light photograph is not in full use, this is that mutual edge distance is narrow mutually with the lamp pearl owing to the lamp pearl, and the lamp pearly-lustre that is positioned at ring shines by the event of the lamp pearl block of outer ring plate.The utility model has changed above-mentioned plug in blowtorch pearl form, LED lamp pearl inserted be welded on each annular and circular PCB wiring board of different big or small levels, to insert the annular PCB wiring board that welds then and encircle little ring, each layer ring flat-plate about 5mm composition pagoda shape led light source illuminator apart, and be built in the lamp body inner chamber from big.Like this, LED ball bubble open shelves that its plane of illumination when bright is not subjected to adjacent lamps pearl and other object every, the quantity of illumination is fully used, and LED lamp pearl luminous efficiency is not fully exerted, and its optical efficiency ratio has now on a horizontal plane and to insert the weldering mode and improve more than 20% after tested.
2. because inserting the weldering form, each LED lamp pearl of the present utility model makes the slotting weldering of polylith annular PCB single face wiring board into by insert weldering at a PCB single face wiring board upper horizontal plane concentrated type, the annular PCB wiring board that to insert then pagoda shape rising from large to small is assembled into the luminous lamp body of LED, each flaggy is apart from being about LED lamp pearl height, so its light that outwards penetrates not by contiguous lamp pearl shelves every, like this, have only 120 because of LED lamp pearl
0The characteristics of luminescence of angle and the dark space that produces obtains bigger expansion, so the plane of illumination of the utility model bulb, optical efficiency are not only high than the LED bulb of existing structure, it is photochromic softer, comfortable.And because increased illuminance, optical efficiency is required more high than original Environment Design, has used bulb less through adjusted ambient lighting, has relatively just saved fund.
