Problems solved by technology

Existing electroplated reflectors generally include a reflective surface coated with a metal film, but because the coating material itself has a high absorption rate of light, for example, the loss rate of the silver-plated film is 5%, and the loss rate of the gold-plated film is 9%. , the loss rate of aluminized film is as high as about 12%, which makes the light output efficiency of lamps with electroplated reflectors low
Moreover, the cost of lighting devices using electroplated reflectors is relatively high

Embodiment 1

[0044] Such as Figure 1 to Figure 6 As shown, the preferred embodiment of the present invention provides a lighting device 100a, which is a spotlight. Specifically, the lighting device 100a includes a lamp body 1a, a light source assembly 2a housed in the lamp body 1a, a fixing structure 3a for installing the light source assembly 2a, and a light distribution assembly for distributing light to the light source assembly 2a, and the lamp body 1a is enclosed. The light-transmitting plate 6a at the light outlet, and the face ring 7a connected with the lamp body 1a to fix the light-transmitting plate 6a on the lamp body 1a. Wherein, the light distribution assembly includes a lens 4a and a reflector 5a. The reflector 5a is cup-shaped and ring-shaped and transparent. After the light emitted by the light source assembly 2a passes through the light distribution of the lens 4a, part of it is directly emitted through the light-transmitting plate 6a, and part of it is reflected. After b...

Embodiment 2

[0060] Such as Figure 12 and Figure 13 As shown, the embodiment of the present invention provides a lighting device 100b, which has an integrated structure. In other alternative embodiments, the lighting device 100b may also be an assembled structure. Specifically, the illuminating device 100b includes a lamp body 1b, a light source assembly 2b accommodated in the lamp body 1b, a light distribution assembly arranged at the front end of the lamp body 1b for distributing light to the light source assembly 2b, and an electric circuit board arranged at the rear end of the lamp body 1b. Sexual junction structure 3b. Wherein, the light distribution assembly includes a lens 4b and a reflector 5b. The reflector 5b is cup-shaped and ring-shaped and transparent. After the light distribution of the light source assembly 2b passes through the lens 4b, part of the light is directly emitted, and part of it is reflected by the reflector 5b. shoot.

Abstract

The invention discloses a lighting device. The lighting device comprises a lamp body, a light source assembly and a light distribution assembly, wherein the light source assembly is stored in the lamp body, the light distribution assembly is used for distributing light for the light source assembly, the light distribution assembly comprises a transparent first optical element and a transparent second optical element, the second optical element is provided with a side wall and a light outlet, the side wall is enclosed so as to form an optical space which communicates with the light outlet, the first optical element is surrounded by the side wall of the second optical element and extends into the optical space, the first optical element is provided with a light inlet surface and a light outlet surface, the light inlet surface is enclosed so as to form a storage chamber, and the light source assembly is arranged in the storage chamber of the first optical element. According to the lighting device disclosed by the invention, the light distribution assembly in the lighting device is combined with two optical elements, the first optical element is used as a general lens for adjusting the light outlet angle, the second optical element is used as a transparent reflector for changing the light outlet direction, the full-emission effect of the reflector can be achieved without electroplating treatment, the cost is low, and the light outlet efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of lighting, and in particular relates to a lighting device. Background technique [0002] Electroplated reflectors are widely used in lighting fixtures, such as downlights, spotlights, ceiling lights, outdoor lighting fixtures and other lighting fixtures. Here, the electroplating reflector mainly plays the role of redistribution of the light emitted by the light source. Existing electroplated reflectors generally include a reflective surface coated with a metal film, but because the coating material itself has a high absorption rate of light, for example, the loss rate of the silver-plated film is 5%, and the loss rate of the gold-plated film is 9%. , the loss rate of the aluminized film is as high as about 12%, which makes the light output efficiency of the lamps with electroplated reflectors low. Moreover, the cost of the lighting device using the electroplated reflector is relatively high. Contents o...
