Embodiment Construction

[0013] Embodiments of the present invention will be described in detail with reference to the drawings.

[0014] The main structure of the point light source 1 includes a housing 11 , a heat sink 12 and a light emitting part 18 . First, the schematic structure of these components will be described, and then the detailed structure of the heat sink 12 will be described.

[0015]

[0016] The housing 11 is made of an insulating material such as ceramics, and includes a cylindrical portion 11a and a protrusion 11b extending from one end of the cylindrical portion 11a. A lighting circuit 17 is housed in the inner space of the cylindrical portion 11a. A metal shell 15 is provided on the outer peripheral surface of the protruding portion 11b, and a metal eyelet 16 is provided at the tip of the protruding portion 11b. Both the case 15 and the eyelet 16 are connected to the lighting circuit 17 through wiring, and serve as power supply terminals for receiving power from an external ...

Abstract

The invention provides a point light source which can replace a halogen bulb with a reflecting mirror. The point light source is characterized by comprising a bowl-shaped radiator with a bottom part and a side face part, a light emitting element, a light control part, a base and a lamp cap; the bowl-shaped radiator is made of light-transmitting ceramic material, the inner circumference of the bowl-shaped radiator is plated with a metal layer to form a reflecting mirror, and a plurality of holes are etched in the metal layer to make the ceramic material exposed; the light emitting element is arranged at the bottom in the radiator; the light control part controls the light emitting element to emit light; the base is internally provided with a circuit for lightening the light emitting element; the lamp cap supplies power to the circuit, the light control part guides part of emitted light to the side face part, and the side face part has the light transmitting property.

Description

technical field [0001] The present invention relates to a point light source and a light bulb-shaped light source having a light emitting element such as an LED (Light Emitting Diode: Light Emitting Diode). Background technique [0002] Halogen bulbs with reflectors are widely used as point light sources such as spotlights in commercial facilities and residences. [0003] In addition, power saving and long life are also emphasized in the field of lighting, and a technology for replacing existing light bulbs with lighting devices having LEDs (hereinafter referred to as LED lighting devices) has been researched and developed. For halogen bulbs with reflectors is no exception, multiple LED lighting units with reflectors are proposed [0004] Generally, LEDs have the characteristic that heat is generated during the lighting process, and the higher the temperature due to the heat, the lower the luminous efficiency. Therefore, in the process of practical application of the LED ...
