Omnibearing LED bulb lamp

Abstract

The invention discloses an omnibearing LED bulb lamp which comprises a lamp base, a radiating shell, a circuit board, an LED light source and a lamp shade, wherein the radiating shell is provided with a convex platform; a cylindrical LED light source is arranged on the platform; a light source rack is in a multiprism shape; the light emitting point is far from the lamp base; the light blocking range of the radiator at the rear end is small; the LED chips on the side and top surfaces of the cylinder head are integrally packaged by a lens; and the rear end of the cylinder head is provided with a reflecting surface. The invention has the advantages of high luminous flux of the lamp body rear end, omnibearing light emitting, uniform illumination intensity, easy packaging of LED chips, low thermal resistance, favorable radiation effect, long service life and the like, and is convenient in processing.

Description

technical field [0001] The invention belongs to the technical field of LED lighting, and in particular relates to an LED bulb lamp. Background technique [0002] With the rapid development of LED technology, LED has gradually become the first choice for new green lighting due to its advantages of energy saving and environmental protection. Since incandescent lamps and electronic energy-saving lamps still occupy a very high proportion in daily use, in order to reduce waste, LED bulb lamps that use existing interfaces and do not need to replace the original traditional lamp bases and circuits came into being. For LED bulb lamps for indoor lighting, the basic requirements for its light intensity distribution and brightness are: the light bulb should not only have omnidirectional light, but also the light intensity distribution should be as uniform as possible, and the luminous flux of the upper and side parts of the bulb should reach a certain value. Avoid uneven light and sha...

AI Technical Summary

Problems solved by technology

Most of the existing LED bulb lamps use plate-type LED integrated module light sources implanted in the bulb, and the light-emitting surface is narrow, which makes it impossible to achieve all-round light.

The Chinese patent No. 200920206369.2 discloses "a bulb lamp". Although it can emit light at a large angle, it has a complicated structure and many contact surfaces. It is not only difficult to manufacture, but also has poor heat dissipation and short service life. Install high-power chips

The Chinese invention patent application with the application number 201010146167.0 discloses "LED bulbs that can improve the luminous flux". The LED module is fixed on the slope. Azimuth lighting requirements, but also has the disadvantages of complex structure, difficult manufacture, poor heat dissipation effect, and short service life

There are also LED bulb lamps that use special lens light distribution, that is, on the basis of existing LED lamps, by installing upward astigmatism lenses on the surrounding LED lamp beads, although the light intensity distribution can meet the standard requirements, but due to different There are differences in the refractive index of colors, which can easily cause inconsistency in light color temperature and cause visual fatigue
