Problems solved by technology

[0013] However, there is a problem that these will increase the size of the lighting circuit, and the lighting circuit cannot be stored in the base member of the same size as that of the halogen lamp. If a large lighting circuit is to be stored, the lamp itself will be enlarged.

no. 1 approach

[0068] 1. Overall structure

[0069] figure 1 Is a perspective view showing the lamp of the first embodiment, figure 2 It is a perspective view of the longitudinal section of the lamp.

[0070] The lamp 1 of the first embodiment is a substitute for a halogen lamp, and the overall shape is the same as that of a conventional halogen lamp with a reflector.

[0071] The lamp 1 is a lamp with a light-emitting element (LED37) as a light source, and includes: a housing 3, which has a bowl shape, and the light-emitting element (LED37) is mounted on the inner surface of the bottom wall 5; a lens 13, which is smaller than the housing 3, And in a state where the light exit surface (63) is located on the opening side of the housing 3, the cover 15 has an opening 61 in the center to expose the light exit surface (63) of the lens 13 from the opening 61. It is installed to cover the opening of the housing 3 in a manner; the hollow base member 17 is attached to the outer surface of the bottom wall...

no. 2 approach

[0123] In the first embodiment, one lens 13 is stored in the housing 3 (the same applies to the LED unit), but a plurality of lenses may be stored in the housing.

[0124] Hereinafter, a mode in which a plurality of lenses are stored, and here are three lenses, will be described as the second embodiment.

[0125] Image 6 Is a schematic diagram illustrating the arrangement relationship between the lens and the electronic components of the second embodiment, Figure 7 Is a view from the back side of the cover, Picture 8 It is a diagram with only the housing and lamp cap components omitted. Again, from Figure 6 to Figure 8 The electronic components of are not specific components, but are schematically represented.

[0126] Such as Picture 8 As shown, the lamp 201 of the second embodiment includes a housing 203, an LED module 205, an insulating cup 207, a plurality (three) of lenses 209, a cover 211, a base member 213, and a lighting circuit 215.

[0127] As in the first embodiment, t...

no. 3 approach

[0178] As a prior art, Patent Document 2 discloses a method such as Picture 11 As shown, a plurality of LEDs 1802 are mounted on the upper surface of the housing 1801, and the lamp 1800 of the lens member 1803 is fixed with screws 1804 from above. However, in the case of the lamp 1800, since the opening 1805 of the housing 1801 is not covered by the lens member 1803, the appearance characteristics in the front view are not good compared with a halogen lamp, an incandescent lamp, and the like.

[0179] So like Picture 12 As shown, in the case of the lamp 1900 of Patent Document 3, the opening 1904 of the housing 1903 in which the LED 1901 and the lens member 1902 are housed is covered with the cover 1904. If it is such a structure, compared with halogen lamps, incandescent lamps, etc., it also has the appearance characteristics in front view that are not inferior.

[0180] However, in a structure such as the lamp 1900, the number of components increases and the amount of the cover...

Abstract

Lamp realizing high brightness without increase in size, including: case 3 that is in conical shape, wherein LEDs 37 are installed on inner surface of bottom 5 of case 3; lens 13 that is smaller than case 3 in size and positioned in case 3 such that light emission face 63 of lens 13 is on opening side of case 3; cover 15 that is installed to cover opening of case 3 so that light emitted from face 63 is extracted to outside of lamp; base member 17 that is hollow inside and attached to outer surface of bottom 5 of case 3 to project toward outside; and lighting circuit 23 that receives electricity via base member 17, and causes LEDs 37 to emit light. Electronic parts 49, 51 and 99 constituting lighting circuit 23 are arranged in distribution in spaces of case 3 and base member 17.

Description

Technical field [0001] The present invention relates to a lamp and a lighting device using a light-emitting element such as an LED (light emitting diode) as a light source. Background technique [0002] In recent years, with the practical use of high-brightness LEDs as an opportunity, an attempt has been made to use a lamp using an LED as a light source as a substitute for a halogen lamp (Patent Document 1). [0003] Generally, a halogen lamp (dichroic beam type) is provided with a reflecting plate, and a protrusion formed by protruding from the bottom of a bowl-shaped reflecting part having a concave reflecting surface on the inner surface to the opposite side of the reflecting surface; The state of the reflecting surface on the optical axis is held by the protrusion; and the base is electrically connected to the filament coil provided inside the arc tube and is provided in the protrusion. [0004] A lamp using LED instead of such a halogen lamp (hereinafter, simply referred to as ...
