Problems solved by technology

Some manufacturers have innovated on this, by placing light-emitting diodes in the reflector to create an effect similar to a point light source, but limited to the surface light source characteristics of LEDs, this improvement still has uneven luminescence and cannot substantially improve And the problem of quantitative control of the light range can only provide spiritual comfort

Embodiment Construction

[0034] The following discussion belongs to but does not limit the protection scope of the claims of the present invention, and the claims shall prevail when judging the rights.

[0035] The realization of the present invention is based on the following two points of consensus:

[0036] 1. In principle, the bulb lamp with built-in point light source can project light to any place except the dark area formed by the shading part of the lamp body;

[0037] 2. For a bulb with a reasonable design, the area that cannot be illuminated by the LED chip closest to the shading part of the lamp body will form a blind area for lighting of the bulb.

[0038] In a preferred embodiment, see figure 2 , The bulb lamp includes a transparent lampshade 3 , a lamp body 1 , four LED chips 2 and a lamp cap 4 . The lamp body 1 includes a cylindrical part 1-1 and a conical part 1-2, wherein the conical part 1-2 is used for installing LED chips. The cylinder part 1-1 and the frustum part 1-2 of the l...

Abstract

The invention belongs to the technical field of LEDs (light-emitting diodes), and provides a bulb lamp and a manufacturing method thereof. The illumination range of an LED chip is widened by the aid of equivalent point light source technology, the problems that the illumination range is not wide enough or an adjusting method is too rough and can only qualitatively but quantitatively solve problems in the prior art are solved, and obvious progressive significance is achieved.

Description

field of invention [0001] The invention belongs to the technical field of LEDs, and in particular relates to a bulb lamp and a manufacturing method thereof. Background technique [0002] Due to the difference in the light-emitting characteristics of LEDs and the structure of light-emitting diodes, the lighting range of LED lamps is limited, which greatly limits the practicability of LEDs. This defect is especially serious in some applications that require a large lighting range, such as bulb lamps or some applications that require lamps to have a consistent light effect in the 4π direction. Some manufacturers have innovated on this, by placing light-emitting diodes in the reflector to create an effect similar to a point light source, but limited to the surface light source characteristics of LEDs, this improvement still has uneven luminescence and cannot substantially improve As well as the issue of quantitative control of the light range, it can only provide spiritual comf...
