Embodiment Construction

[0014] Please refer to figure 2 and image 3 , is a schematic structural diagram of the lighting device 10 provided by the first embodiment of the present invention. The lighting device 10 includes a casing 11 , a supporting bracket 12 and a plurality of light emitting units 13 .

[0015] The casing 11 has a hollow tubular structure, and three protrusions 110 extending along the axial direction of the casing 11 are formed on the inner surface thereof. Preferably, the three protrusions 110 are integrally formed with the casing 11 and uniformly arranged on the inner surface of the casing 11 along the circumferential direction. Each protrusion 110 is formed with two sliding grooves 111 extending axially along the parallel casing 11 , and the cross section of the sliding grooves 111 is U-shaped. The casing 11 is made of transparent material, such as glass, resin and so on. Of course, the cross section of the slide groove 111 can also be in other shapes, such as V-shape and so...

Abstract

The invention discloses a lighting device. The lighting device comprises a tubular shell, a bearing bracket and a plurality of light emitting units, wherein a plurality of bumps which extend in the axial direction along the parallel shell are formed on the inner surface of the shell; at least one sliding chute which extends in the axial direction of the parallel shell is formed on each bump; the bearing bracket is accommodated in the shell and comprises at least three bearing plates; a columnar structure is formed by enclosing the at least three bearing plates; the two ends of each bearing plate are penetrated into two sliding chutes respectively; the plurality of light emitting units are arranged on the at least three bearing plates respectively; and the light emitted by the plurality of light emitting units is emitted from the shell.

Description

technical field [0001] The invention relates to an illuminating device, in particular to an illuminating device with isotropic distribution of light distribution curve and easy assembly. Background technique [0002] Light Emitting Diode (LED, Light Emitting Diode) has the advantages of high brightness, low operating voltage, low power consumption, easy matching with integrated circuits, simple driving, and long life, so it can be used as a light source and widely used in the lighting field. For details, please refer to Joseph Bielecki et al. wrote Thermal Considerations for LED Components in an Automotive Lamp in the 2007IEEE, 23rd IEEE SEMI THERM Symposium. A light emitting diode is a semiconductor element that converts electrical current into light of a specific wavelength range. [0003] The light distribution curve of a light source represents the distribution of the light emitted by the light source in space. The light distribution curve of the traditional light sour...
