Embodiment Construction

[0052] figure 1 Shown is an exploded view of a lighting device according to an embodiment of the present invention. Please refer to figure 1 , the lighting device 100 includes a sleeve 110 , a light emitting element 120 , a driver 130 , a light guide rod 140 , a lamp cap 150 , a locking member 160 and a reflective layer 170 . The sleeve 110 is a hollow cylindrical member, so that the light emitting element 120 , the light guide rod 140 and the reflective layer 170 are assembled into the sleeve 110 from the first end 110A. The driver 130 is assembled into the sleeve 110 by the second end 110B. The lamp cap 150 is connected to the sleeve 110 such that the driver 130 is sandwiched between the sleeve 110 and the lamp cap 150 . The locking member 160 can be used to fix the light guide rod 140 inserted into the sleeve 110 .

[0053] In this embodiment, the reflective layer 170 is substantially attached to the surface of the light guide rod 140 , and the two can be manufactured t...

Abstract

The invention provides a lighting device. The lighting device comprises a sleeve, a light-emitting element, a driver and a light guide rod, wherein the sleeve is made of heat conduction insulating materials and comprises a platform, a first sleeve body part and a second sleeve body part, the first sleeve body part and the second sleeve body part are connected to the two opposite sides of the platform, a first containing space is defined by the inner side of the first sleeve body part and the first face of the platform, and a second containing space is defined by the inner side of the second sleeve body part and the second face of the platform. The light-emitting element is arranged in the first containing space and substantially borne on the first face of the platform. The driver is arranged in the second containing space of the sleeve in a contact mode. The light guide rod is arranged in the first containing space and partially stretches out of the first sleeve body part, and the light-emitting face of the light-emitting element faces towards the light guide rod.

Description

technical field [0001] The present invention relates to a lighting device, and in particular to a lighting device with a heat dissipation component. Background technique [0002] Traditional lighting devices are provided by fluorescent lamps and incandescent bulbs. As the luminous efficiency of light emitting diodes (Light Emitting Diodes, referred to as LEDs) continues to increase, light emitting diodes tend to gradually replace fluorescent lamps and incandescent bulbs and be used in lighting devices. Compared with traditional light bulbs, light-emitting diodes have absolute advantages, such as small size, long life, low voltage / current drive, not easy to break, mercury-free (no pollution problem), and good luminous efficiency (power saving). Whether it is a fluorescent lamp, an incandescent bulb or a light-emitting diode, with the improvement of the lighting brightness requirements, the heat dissipation efficiency of the lighting device has become an important factor affe...
