Description

The luminous bulb lamp of comprehensive LED
Technical field
The present invention relates to a kind of lighting technical field, particularly the luminous bulb lamp of comprehensive LED.
Background technology
Because light emitting diode is a kind of high efficiency cold light light-emitting component that converts electrical energy into luminous energy, and have advantages such as energy-saving and environmental protection, high efficiency, small size, long-life, so LED(Light Emitting Diode, light emitting diode) light fixture more and more is subjected to people's favor, and the LED light fixture replaces traditional incandescent lamp to become a kind of main flow trend with fluorescent lamp.Because LED has the characteristics of directive property, the LED bulb lamp of electricity-saving lamp is can only be forward luminous and can not be luminous backward, caused the lighting angle of LED ball bubble of existing market less than 180 °, like this, when the lighting environment needs are omnibearing luminous, the ball bubble of this form just can not be employed, therefore along with a kind of omnibearing bulb lamp has just appearred in development of science and technology.
For example: as Fig. 1, Fig. 2, shown in Figure 3, the patent No. that State Patent Office announces is 201010583096.0 a kind of comprehensive LED bulb lamp, include lamp holder 1, radiating shell 9, led light source 3 and diffusion lampshade 5, be provided with LED drive unit 4 in described radiating shell 9 cavitys, it is characterized in that described radiating shell 9 is along being axially arranged with cambered outwards platform 8, platform 8 end faces are provided with led light source 3, described led light source 3 is column cap integrated light-emitting light source, its encapsulation support body 10 is provided with polygon prism shape head, end face and side at column cap are equipped with led chip 11, support body 10 column cap rear ends are provided with ring-type reflective surface 12, it mainly is to realize that by reflective surface lamp body rear end luminous flux is big, realize omnibearing luminous, but because the size of the reflective surface of this structure is restricted, therefore cause the poor effect of the comprehensive illumination of this comprehensive LED bulb lamp, therefore need to improve.
Summary of the invention
The objective of the invention is provides a kind of light fixture that can make luminous evenly in all directions in order to solve above-mentioned the deficiencies in the prior art, realizes lighting angle greater than 270 °, thereby has effectively realized the omnibearing luminous luminous bulb lamp of comprehensive LED.
To achieve these goals, the luminous bulb lamp of comprehensive LED that the present invention is designed, comprise lamp holder, housing, led light source, the LED drive unit, diffusion lampshade and plastic feet, described plastic feet is located between housing and the lamp holder, described housing comprises table top, described diffusion lampshade is sheathed on the whole table top, described led light source comprises first led light source and second led light source, described first led light source is embedded at the inboard of table top top, described second led light source is located on the back side of downside with respect to first led light source of table top, and the direction of illumination of described first led light source and second led light source is opposite, outer wall in the lower end of table top is arranged with reflector, the diameter of described reflector cup upper end is less than the diameter of reflector cup lower end, and the lower end with respect to the reflector cup on the outer wall of reflector is provided with diffuse surface.Described diffuse surface is that a ring reaches above indent ring-type or outer convex hoop shape or evagination is spherical or the diffuse surface of convex chondritic.
The principle of luminosity of this structure is: directive top after the light beam process diffusion lampshade diffusion that first led light source sends, and after the while light velocity spread through the diffusion lampshade, angle increases, and was luminous even; And the light beam that second led light source sends is towards the below, therefore a part of light beam is through directive below, diffusion lampshade diffusion back, after the diffuse surface reflection of part light beam directive reflector male and fomale(M﹠F), direction changes, again through other direction irradiations of directive of diffusion lampshade diffusion back, multi-beam is through the reflector diffuse surface with after spreading the lampshade diffusion like this, disperse to all directions, thereby can make the led light source lighting angle greater than 270 °, luminous even, thus effectively realized omnibearing luminous effect.
Bigger in order to spread angle, described diffusion lampshade comprises the first diffusion lampshade and the second diffusion lampshade, the described first diffusion lampshade covers at outside first led light source of table top upper end, and the described second diffusion lampshade covers at the lower end of table top with respect to the outside of reflector.The first diffusion lampshade and the second diffusion lampshade can adopt different materials.
In order to play effective diffusion, described housing is radiator structure, and comprises following radiator and the table top of separately design, and described LED drive unit is located in the plastic feet, and fixedly connected by plastic feet between described down radiator and the lamp holder, described table top is connected with following radiator.
In order to make overall structure simpler, reduce the set-up time when mounted, described table top and following radiator are structure as a whole.
The luminous bulb lamp of comprehensive LED that the present invention obtains, by above-mentioned design: the light beam that first led light source sends is through directive top, diffusion lampshade diffusion back, simultaneously the light velocity through the diffusion of diffusion lampshade after, angle increases, luminous evenly; And the light beam that second led light source sends is towards the below, therefore a part of light beam is through directive below, diffusion lampshade diffusion back, after the diffuse surface reflection of part light beam directive reflector male and fomale(M﹠F), direction changes, again through other direction irradiations of directive of diffusion lampshade diffusion back, multi-beam is through the reflector diffuse surface with after spreading the lampshade diffusion like this, disperse to all directions, thereby can make the led light source lighting angle greater than 270 °, luminous even, thus effectively realized omnibearing luminous effect.
