Light emitting diode (LED) full light angle bulb

Abstract

The invention provides a light emitting diode (LED) full light angle bulb, which comprises a lamp housing and a light source and a reflecting unit which are arranged in the lamp housing, wherein the light source at least comprises a first light source group, a second light source group and a third light source group; the reflecting unit at least comprises a first reflector and a second reflector; the lamp housing is partitioned into a first area, a second area and a third area by the first reflector and the second reflector; and the first light source group, the second light source group and the third light source group are respectively correspondingly arranged in the first area, the second area and the third area. The heat produced by the light source in the LED full light angle bulb is distributed uniformly, so that the service life of the bulb is prolonged; the design space of a power supply is enlarged, and the power of the bulb can be improved as required; and the contour of the bulb can be made to be as same as that of a classical filament lamp so as to accord with the traditional aesthetic standard.

Description

technical field [0001] The invention relates to the technical field of lighting fixtures, in particular to an LED full-light angle bulb. Background technique [0002] With the rapid development of LED technology, the standards of LED lighting products have gradually been established. In particular, the Energy Star (Energy Star, hereinafter referred to as ES) standard promoted by the U.S. Department of Energy and the U.S. Environmental Protection Agency has gradually become an entry barrier for LED lighting products in the U.S. market. Among them, ES has the following requirements for luminous characteristics for Class A bulbs (that is, bulbs in the shape of standard incandescent lamps) in addition to basic photoelectric performance requirements such as luminous flux output and luminous efficacy: the light intensity change within γ0-135° cannot exceed this 20% of the average light intensity within the range, the luminous flux within γ135-180° cannot be lower than 5% of the t...

AI Technical Summary

Problems solved by technology

However, the disadvantages of this solution are: the cost of the phosphor is relatively high, and its yellow color makes the appearance of this kind of bulb not widely accepted, and the production operation of the side-emitting lamp panel is troublesome.

The disadvantage of this solution is that a bulb with a large solid angle range is required, so that this kind of bulb does not have enough power supply design space, and the heat of the LED is concentrated, making it difficult to make a higher power product
