Problems solved by technology

Electroplated reflectors generally include a reflective surface coated with a layer of metal film, but because the coating material itself has a high absorption rate of light, for example, the loss rate of silver-plated film is 5%, the loss rate of gold-plated film is 9%, and the loss rate of aluminum-plated film is 9%. The loss rate of the film is as high as about 12%, which makes the light output efficiency of the lamps with electroplating reflectors low

Embodiment 1

[0048] Such as Figure 1 to Figure 4 As shown, the embodiment of the present invention provides a lighting device 100a, which is a spotlight. Specifically, the illuminating device 100a includes a lamp body 1a, an optical element 2a connected to the lamp body 1a, a heat sink 6a housed in the lamp body 1a, a drive power supply assembly 4a housed in the heat sink 6a, a light source assembly 3a and a A reflection device 5a for secondary light distribution of the light source assembly 3a, wherein the light source assembly 3a is arranged at one end of the reflection device 5a. It should be noted that the reflector 5a is cup-shaped and transparent, and part of the light emitted by the light source assembly 3a directly exits through the optical element 2a, and part of it is reflected by the reflector 5a and then exits from the optical element 2a.

[0049] In the following, each component and the connection relationship between the components in the lighting device 100a provided by th...

Embodiment 2

[0062] Such as Figure 9 to Figure 12 As shown, the embodiment of the present invention provides a lighting device 100b, which is a downlight. Specifically, the lighting device 100b includes a lamp body 1b, an optical element 2b connected to the front end of the lamp body 1b, a connecting piece 6b sleeved on the periphery of the lamp body 1b, two snap springs 8b connected to the connecting piece 6b, and a connecting piece connected to the lamp body 1b. The driving power supply box 7b at the rear end of the body 1b, the light source assembly 3b housed in the lamp body 1b and the reflection device 5b for secondary light distribution for the light source assembly 3b, and the driving power supply box 7b housed in the light source assembly 3b are electrically connected. The driving power supply assembly 4b is connected, wherein the light source assembly 3b is arranged at one end of the reflection device 5b. It should be noted that the reflector 5b is ring-shaped and transparent, p...

Embodiment 3

[0075] Such as Figure 13 to Figure 16 As shown, the embodiment of the present invention provides an illuminating device 100c, which includes a lamp body 1c, an optical element 2c connected to the front end of the lamp body 1c, a face ring 6c for connecting the lamp body 1c and the optical element 2c, housed in The light source assembly 3c in the lamp body 1c, the reflection device 5c for secondary light distribution for the light source assembly 3c, and the uniform plate 4c covering the light outlet of the reflection device 5c, wherein the light source assembly 3c is arranged at the light entrance of the reflection device 5c one end. It should be noted that the reflecting device 5c is ring-shaped and transparent, and part of the light emitted by the light source assembly 3c is directly emitted through the homogenizing plate 4c, partly reflected by the reflecting device 5c, and then homogenized by the homogenizing plate 4c, finally by the optical element 2c shoot. The lighti...

Abstract

The invention discloses a lighting device comprising a light body, an optical element connected with the light body, a light source assembly held in the light body, a reflection device for secondary light distribution of the light source assembly, and a driving power assembly. The reflection device is annular and transparent and is provided with a light inlet and a light outlet which are located in the two ends. The reflection device comprises an inner surface and an outer surface. The outer surface comprises a plurality of continuously arranged sawtooth structures. Each sawtooth structure comprises a first reflection face and a second reflection face which intersect. The two ends of each sawtooth structure extend to the light inlet and the light outlet correspondingly. The light source assembly is arranged at the light inlet of the reflection device. The light body comprises a projection or a clamping structure. The optical element comprises a clamping structure or a projection. The projection is held in the clamping structure, so that the light body and the optical element are clamped. According to the lighting device, incident light rays from the inner surface can all emerge with a total reflection optical effect, and luminous efficiency is improved under the circumstance without the need for electroplating treatment.

Description

[0001] This application is a divisional application of the original invention application (application number 201710386879.1, application date May 26, 2017), and the invention name of the original application is "lighting device". technical field [0002] The invention belongs to the technical field of lighting, and in particular relates to a lighting device. Background technique [0003] Existing electroplated reflectors are widely used in commercial lamps, such as downlights, spotlights, ceiling lights, outdoor lamps and other lighting fixtures. The electroplating reflector mainly plays the role of secondary light distribution for the light emitted by the light source. Electroplated reflectors generally include a reflective surface coated with a layer of metal film, but because the coating material itself has a high absorption rate of light, for example, the loss rate of silver-plated film is 5%, the loss rate of gold-plated film is 9%, and the loss rate of aluminum-plated...
