Abstract
The utility model discloses an LED lamp bulb, which comprises LEDs, a base and a lamp shade arranged on the base. A reflector mirror is arranged on the inner side of the lamp shade, and at least two LEDs are arranged between the lamp shade and the reflector mirror. The reflector mirror is disposed inside the lamp shade while the LEDs are disposed between the lamp shade and the reflector mirror, when the LEDs emit light, part of the direct light is directly refracted to outside through the lamp shade, the other part of direct light is reflected, and reflected light exactly irradiates onto the surface of the reflector mirror and is reflected again by the reflector mirror to emit outside through the lamp shade, thereby greatly reducing light loss and increasing lighting brightness.
Description
Technical field
The utility model relates to a kind of lighting, and being specifically related to a kind of is the bulb of light source with light emitting diode (LED).
Background technology
At present, the light emitting source that indoor illumination light fitting adopted such as desk lamp is based on incandescent light bulb or fluorescent tube basically.And the electro-optical efficiency of incandescent light bulb or fluorescent tube is all lower, and its caloric value is big, and service life is shorter.
LED has advantages such as volume is little, caloric value is low, power consumption is low, the life-span is long as a kind of emerging light emitting semiconductor device, and therefore having begun to occur some on the market is the light fixture of light source with LED.Existing LED light fixture mostly is to form at the peripheral directly sheathed lampshade of LED, and its light loss consumption is bigger, and light extraction efficiency is lower.
Summary of the invention
The utility model purpose provides a kind of LED bulb, and it has higher light-emitting efficiency.
For achieving the above object, the technical solution adopted in the utility model is: a kind of LED bulb comprises LED, base and is provided with lampshade on the base that described lampshade inboard is provided with speculum, is provided with at least 2 LED between described lampshade and the speculum.
Above, described speculum can be the speculum cover, its top is connected with lampshade, and its bottom is provided with LED, thereby from the light that LED sends, part direct projection light directly is refracted to the outside by lampshade, another part direct projection light reflects, and reflection ray is just in time beaten the surface at speculum, by speculum secondary reflection and penetrate by lampshade again, thereby reduced the light loss consumption greatly, improved illumination brightness.
The quantity of described LED is set according to the size and the actual conditions of bulb, optimized technical scheme, and described LED is 4, and circumferential uniform setting.LED is circumferentially uniform, and that the distribution that can make irradiates light is set is comparatively even.
In the technique scheme, also be provided with power module in the described base, power module is electrically connected with LED.
In the technique scheme, the bottom of described base is provided with metal spiral shell tail.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1, the utility model is provided with speculum in the lampshade inboard, and LED is located between lampshade and the speculum, thereby when LED is luminous, part direct projection light directly is refracted to the outside by lampshade, another part direct projection light reflects, and reflection ray is just in time beaten the surface at speculum, by speculum secondary reflection and penetrating by lampshade again, thereby reduced the light loss consumption greatly, improved illumination brightness.
2, the surface of speculum of the present utility model can be made level and smooth streamlinedly, and it is also very even, soft therefore to reflex to light from outside, does not have lofty sensation.
3, the utility model is simple in structure, is easy to make, and production cost is also lower simultaneously, is fit to apply.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment one;
Fig. 2 is the A-A cutaway view of Fig. 1.
Wherein: 1, LED; 2, base; 3, lampshade; 4, speculum; 5, power module; 6, metal spiral shell tail.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment one
Shown in Fig. 1～2, a kind of LED bulb comprises LED1, base 2 and is provided with lampshade 3 on the base that described lampshade 3 inboards are provided with speculum 4, are provided with 4 LED between described lampshade and the speculum, the circumferential uniform setting of described LED.
Also be provided with power module 5 in the described base, power module is electrically connected with LED.
The bottom of described base is provided with metal spiral shell tail 6.Metal spiral shell tail is the standard lamp joint, and whole lamp inserts civil power 220V by it.Metal spiral shell tail links to each other with power module by electric wire, and with externally fed AC220V input power module, power module will exchange the direct current that AC220V is converted to the LED requirement specification, finish the power supply to LED.
Lampshade can adopt transparent acrylic to make, and base adopts the plastic cement base, and base is an insulating material, plays the effect of isolating civil power, and transparent acrylic outer cover can be fixedlyed connected with base by buckle.The power module of packing in plastic cement base inside.
When LED is luminous, part direct projection light directly is refracted to the outside by transparent acrylic lampshade, when running into transparent acrylic outer cover, another part direct projection light reflects because of incidence angle is bigger, reflection ray is just in time beaten the surface at speculum, speculum can be made by the bright and clean plastic material of white, can be with fiber-loss very little and secondary reflection again, this secondary reflection is little because of incidence angle, can be refracted to the outside by transparent acrylic outer cover, around illuminating; Therefore streamlined and very level and smooth because of mirror surface, it is also very even, soft to reflex to light from outside, does not have lofty sensation.
Claims (4)
1. LED bulb comprises LED (1), base (2) and is provided with lampshade (3) on the base that it is characterized in that: described lampshade (3) inboard is provided with speculum (4), is provided with at least 2 LED between described lampshade and the speculum.
