Background technology:
Traditional incandescent lamp bulb uses osram lamp, though this bulb brightness height, its luminous efficiency is low, quite power consumption, and along with the generation of the high heat of high temperature, tungsten filament is under the condition of high temperature for a long time and blows easily when luminous, so the tengsten lamp life-span is short.White light LEDs is a novel illumination light fixture of developing operation in recent years, compares with traditional light fixture, has advantages such as low pressure, low-power consumption, luminous efficiency height, high reliability, long-life, is a kind of environmental protection, energy-conservation novel green lighting source of meeting.Present LED lighting bulb, see shown in Figure 1, this LED lighting bulb primary structure comprises lamp holder 101, lamp housing 102, Transparent lamp shade 103, in lamp housing 102, be provided with drive circuit board 104 and substrate 105, substrate 105 is provided with a plurality of LED lamps 106, and behind the connection power supply, a plurality of LED lamps are simultaneously luminous, can reach certain brightness, realize the effect of illumination.The refractive index of air is low in Transparent lamp shade 103 inner chambers, and LED lamp 106 luminous directionality will cause Transparent lamp shade 103 top brightness to be higher than below brightness, and bulb sphere color and luster is inhomogeneous, and angular field of view is little, and ball bubble overall brightness is low.
The utility model content:
The purpose of this utility model is exactly to provide a kind of LED lighting bulb at the weak point of prior art existence, and it has overcome the shortcoming that the brightness of common LED lighting bulb is low, color and luster is inhomogeneous, angular field of view is little.
To achieve these goals, the technical solution adopted in the utility model is: it comprises metallic lamp holder, the metallic lamp holder inner chamber is fixed with the heat conduction lamp housing, be provided with drive circuit board at heat conduction lamp housing inner chamber, drive circuit board is received metal substrate by connecting wire, at the metal substrate upper surface except being furnished with at least one LED lamp, other zone of metal substrate upper surface also is furnished with one deck refractive index greater than 2.0 glass microballoon, the heat conduction lamp housing is supporting Transparent lamp shade, metal substrate and LED lamp are sealed in the Transparent lamp shade, the Transparent lamp shade inner surface scribbles the layer of transparent film, the refractive index of hyaline membrane greater than the refractive index of air less than the refractive index of Transparent lamp shade.
Heat conduction envelope inner wall top is provided with a flight, and metal substrate is fixed on the flight by the metal screw.
Metal substrate and heat conduction lamp housing assembling back form a groove, and Transparent lamp shade is plugged in the groove and by the heat conduction viscose glue and fixes.
The metallic lamp holder surface has at least one passage, and passage is communicated with the inner chamber of heat conduction lamp housing.
The Transparent lamp shade inner surface scribbles the layer of transparent film, the refractive index of hyaline membrane greater than the refractive index of air less than the refractive index of Transparent lamp shade, not only can improve LED optical transmission rate, and the light that sends when the LED lamp reflects through hyaline membrane, evenly mixed and outside the ejaculation simultaneously of transmission, the high-refraction glass bead of reflection ray directive metal substrate upper surface, glass microballoon is with the reverse retroreflecting of reflection ray, produce the light parallel with reflection ray, reflect again after returning the directive hyaline membrane, transmission is evenly mixed outwards to be penetrated, bulb brightness is improved, color and luster is even, and the visual angle increases.In addition, the heat of the luminous generation of LED is transmitted on the heat conduction lamp housing through metal substrate, and contact area is big, very fast heat is outwards distributed, so the LED life-span is long.
