Description

A kind of LED bulb lamp
Technical field
The present invention relates to a kind of LED illuminating lamp, relate in particular to a kind of LED bulb lamp.
Background technology
Full-fledged along with the LED technology, the LED illumination replaces traditional lighting also becomes a kind of inexorable trend.Major companies such as CREE, Philip, Ou Silang produce the high-power lamp pearl that light efficiency reaches 120LM/W in a large number, and domestic many encapsulation company encapsulation technology is also constantly progressive and ripe, and paster 3528,5630,5050 etc. is used widely.Simultaneously, also slowly put into effect, make the developing direction of LED light fixture clear gradually with respect to the industry standard and the international standard of light fixture.Wherein the star with american energy is an example, and its standard is just made very detailed technical parameter regulation at the LED bulb lamp.The design main flow of LED bulb lamp is in the market: 1, aluminium finned radiator, the easy dust stratification of the long-time use of this kind radiator influences radiating effect.2, lighting angle is less than 180 °, and illuminating effect is not good, perhaps in some place or the area can not use.
Existing LED illuminating lamp is in order to solve this heat dissipation problem, adopt tubular structure, airtight space of the inner formation of PCB circuit board, lamp holder and radiator mainly relies on this confined space heat radiation, heat loss through convection can't be realized, heat dissipation problem can not be fundamentally solved.
In the day for announcing is that July 13, publication number in 2011 are that the utility model patent that CN201897126U, name are called " the LED bulb lamp that a kind of wide-angle is luminous " has disclosed the luminous LED bulb lamp of a kind of wide-angle, be trapezoidal radiator by circular cylindrical cross section being set at diffusing top of holding the device shell, the mode that the lamp pearl is set in radiator top and terraced portion realizes wide-angle, is to adopt the polylith aluminium base to be installed in different angles to realize that wide-angle is luminous.But because the outer surface of radiator is not smooth, the easy dust stratification of the long-time use of this kind radiator influences radiating effect.
Summary of the invention
The present invention is directed to the defective that radiating effect is not good in the prior art, lighting angle is little, a kind of LED bulb lamp is provided.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of LED bulb lamp, comprise lamp holder, lamp socket, radiating shell, lens, lampshade, constant-current supply, the PCB circuit board, the led light source array, described lamp holder is screwed in an end of lamp socket, constant-current supply is seated in the lamp socket, the PCB circuit board tightly is locked in the other end of lamp socket, radiating shell is socketed on the lamp socket, described lens is a horn shape, described led light source array comprises the first led light source array and the second led light source array, the described first led light source array is positioned at the inside of lens horn shape, and the described second led light source array is positioned at the outside of lens horn shape.Adopt the horn shape lens, and led light source is divided into two arrays, send after the inner surface reflection of light that the led light source array of winning is sent through lens, the light of the second led light source array sends after reflecting through the lens outer surface, the light beam that the led light source array sends sends to the about 60-150 of a horizontal direction ° axial symmetry direction after the reflection of lens first reflecting surface, the light beam that the second led light source array sends sends to the about 0-90 of a horizontal direction ° axial symmetry direction after second reflecting surface reflection of lens, so just obtain isotropic directivity and be lighting angle greater than 300 ° the light effect that goes out, and distribution of light is even, good illumination effect.
Above-mentioned a kind of LED bulb lamp, described lens is two-sided reflective, and the outside of lens horn shape is provided with the hole, and this hole is corresponding with the described second led light source array.Make that the reflecting effect of the second led light source array is better, realize that omnibearing luminous effect is better.
Above-mentioned a kind of LED bulb lamp is established the fin that is evenly distributed in the described radiating shell, an end of radiating shell is provided with the hole that is evenly distributed, and an end of described lamp socket is provided with the hole.When the LED bulb lamp was worked, cold wind entered from the hole on the radiating shell, and coming out in the hole from lamp socket, has formed the heat passage that air inlet and air outlet are arranged, and utilizes the principle of fluidics, reduced system's thermal resistance, increased the service life of product.
The outer surface of above-mentioned radiating shell is smooth.The outer surface that has overcome radiator is rough, uses easy dust stratification for a long time, influences the defective of radiating effect.
Above-mentioned a kind of LED bulb lamp is provided with the groove position in the described lamp socket, constant-current supply is fixed in the lamp socket by described groove position.Simple in structure, firm.
The present invention has following beneficial effect:
During the work of LED bulb lamp, behind the light process lens luminous intensity distribution that led array sends, light beam sends from different perspectives and reaches the luminous effect of isotropic directivity.
Description of drawings
Fig. 1 is a front of the present invention sectional structure chart;
Fig. 2 is a constitutional detail explosive view of the present invention;
Fig. 3 is array of source structure of the present invention and lens syndeton schematic diagram.
The specific embodiment
Below in conjunction with the specific embodiment and accompanying drawing the present invention is described in further detail, but they are not limitations of the present invention:
Embodiment 1
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the LED bulb lamp that a kind of isotropic directivity is luminous, comprise lamp holder 1, lamp socket 2, radiating shell 3, lens 4, lampshade 5, constant-current supply 6, PCB circuit board 7, led light source array 8, described lens 4 is a horn shape, described led light source array 8 comprises the first led light source array 81 and the second led light source array 82, the described first led light source array 81 is positioned at the inside of lens 4 horn shapes, and the described second led light source array 82 is positioned at the outside of lens 4 horn shapes.
