Problems solved by technology

[0007] However, so far, none of the existing technologies can better focus the light
Furthermore, none of the existing technologies can meet the new regulations of the European Union, such as the light output within an angle of 120° is not less than 80%, or the light output of a 22W bulb reaches 1297lm, etc.

Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0039] In order to make the light emitted by the light-emitting part of the bulb more concentrated, the present invention proposes a new reflector lamp design, including: a base, a ballast part, a light-emitting part and a lamp housing. Wherein, the lamp housing can be made of opaque material (such as plastic), including a first part and a second part; the light emitting part is divided into a first area, a second area and a third area.

[0040] The first part of the lamp housing is used to surround the first area of ​​the light-emitting part, making the first area of ​​the light-emitting part opaque; The third area is revealed. It should be pointed out that the degree of closeness of wrapping and occlusion is different. The first part of the lamp hou...

Abstract

The invention discloses a reflecting lamp, which comprises a base, a ballast part, a luminous part and a lamp shell, wherein the lamp shell comprises a first part and a second part; the first part of the lamp shell is used for surrounding a first area of the luminous part, so that the first area of the luminous part is light-proof; the second part of the lamp shell is used for shielding a second area of the luminous part and exposing a third area of the luminous part; a reflective coating is coated on an inner wall of the second part of the lamp shell, and is used for reflecting light rays which are projected by the luminous part to the second part, so that the light rays are transmitted through the third area of the luminous part. The reflective coating enables the light rays transmitted from 120 degrees three-dimensional angle of the third area of the luminous part less than the light rays sent from the luminous part by 80%. Therefore, by the reflecting lamp, the emitted light rays are more converged.

Description

technical field [0001] The invention relates to the field of optical lighting, in particular to a reflector lamp. Background technique [0002] A reflector lamp is a type of light bulb that has a reflector or covering inside to reflect light to the front of the light emitting part of the light bulb. Reflector lamps can spread or direct light to a specific area. According to the definition of the American National Standards Institute (ANSI), there are four basic shapes of light-emitting parts of reflector lamps: reflector (reflector, R), aluminum-coated Parabolic reflector (parabolic aluminized reflector, PAR), convex reflector (bulged reflector, BR), elliptical reflector (elliptical reflector, ER). These bulbs are mainly used for flood lighting, spot lighting, down spot lighting, etc. [0003] Based on the working principle of fluorescent gas discharge and electromagnetic induction, a series of electrodeless fluorescent reflector lamps have been developed and brought to th...
