Problems solved by technology

Since the high-efficiency and large-angle LED bulb PCB board is provided with heat dissipation columns to dissipate heat, the heat generated by these LED chips is only transmitted and dissipated by the adjacent side, which may easily cause untimely heat dissipation, reduce the service life of these LED chips, and require Set up a larger heat dissipation column and PCB board, which increases the weight and cost of the high-efficiency large-angle LED bulb

Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] figure 1 It is a three-dimensional exploded view of an external heat dissipation LED lamp 100 according to the first embodiment of the present invention. The external heat dissipation LED lamp 100 includes a lamp base body 10, a bulb shell 20, a light emitting element 40 and a light distribution element 30. The bulb shell 20 is covered on the lamp base The top of the body 10 accommodates the light distribution element 30 and the light emitting element 40 therein.

[0019] Please refer to Figure 1 to Figure 4 , the luminous element 40 includes a substrate 41 and an LED light source 42 disposed on the substrate 41 (such as image 3 shown). The base plate 41 has a ring structure and includes a plurality of LED light sources 42 arranged on the base plate 41 at intervals and arranged in a ring around the center of the base plate...

Abstract

An outward-radiation LED lamp comprises a lamp base, a bulb housing, an illuminating unit and a light distribution unit. The bulb housing covers the top of the lamp base; the illuminating unit comprises a substrate and an LED light source; the light distribution unit comprises a light distribution member and a heat transfer member thermally connected with the light distribution member, and the heat transfer member is arranged at the top of the lamp base; both the light distribution member and the heat transfer member are made of materials with good heat transfer or radiation capacities, the heat distribution member is made of transparent or semitransparent materials and comprises a mounting face and a light emitting face, and an accommodating slot is formed in the mounting face; the substrate is fixed onto the mounting face and the LED light source on the substrate is accommodated inside the accommodating slot; the illuminating face is thermally connected with the mounting face of the light distribution member; the light emitting face faces towards the bulb housing. The outward-radiation LED lamp has the advantages of timely radiation, light weight and assembling convenience.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to an outward heat dissipation LED lamp. Background technique [0002] At present, LED lamps have been widely used in the field of lighting, but the heat generation of LED lamps directly affects the life of LED lamps. Existing LED lights usually use a light source connected to a metal or ceramic radiator for heat dissipation. In order to improve the heat dissipation effect, a larger radiator is often required; at the same time, in order to achieve a large angle of light, the LED light source usually needs to be installed on a three-dimensional column. . For example, the date of authorization announcement is October 31, 2012, and the Chinese utility model patent with the patent number 201220060615.X discloses a high-efficiency and large-angle LED bulb. The high-efficiency large-angle LED light bulb includes a base shell, a lamp holder, a constant current power supply, a cover plate, a h...
