Embodiment Construction

[0024] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.

[0025] Such as Figure 1-3 As shown, a diffuse reflection lighting device includes: LED2 installed on the lamp stand 1, and a reflector 3 toward which the light of the LED2 shines. On the high reflection film of 3, the reflector 3 can reflect the light of LED2 from the light outlet of the lamp, and the included angle between the center ray of the light emitted by LED2 and the light irradiated by the light outlet is 45°-180°. The LED2 faces away from the lamp holder 1, and irradiates all the light on the reflector 3. Through the reflection of the reflector 3, the light path turns 45°-180° and irradiates through the light outlet of the lamp. Th...

Abstract

The invention relates to a diffuse reflection illumination device which comprises LEDs installed on a lamp holder and a reflector towards which the LEDs irradiate light. A high reflecting film is attached to the surface of the reflector. The cross section of the portion, with the high reflecting film, of the reflector is of a continuous multi-fold-line structure. The reflector can reflect the light of the LEDs from a lamp light-emitting opening. The lamp holder is arranged on the edge of one side of the reflector. The high reflecting film comprises a plurality of high polymer disordered spinning layers. Each high polymer disordered spinning layer is a sheet layer of a multi-hole structure formed by interweaving high polymer filaments. The high polymer filaments of the layers are uniform in fineness. The angle between the reflector and the lamp holder is controlled to reflect the light out through the reflector, the light is uniformly and softly distributed, the brightness is improved, and photometric data are full; a set of LED lamp bars correspond to the reflector, and the LED lamp bars are configured on the side edges of the reflector, so that different angles and positions of lamps of various types are correspondingly adjusted, and different requirements can be met.

Description

technical field [0001] The invention relates to a diffuse reflection lamp, in particular to a diffuse reflection lighting device. Background technique [0002] The reflective materials used in traditional day-off lights, high-bay lights and tunnel lights are all matte aluminum reflectors are prone to rust, resulting in reflectivity that is less than 50% with the use of time and the impact of the environment, which is a serious waste of electric energy; at the same time The light source in the prior art can directly irradiate light out of the light outlet of the lamp, so that the uniformity of the light cannot be controlled, and dazzling phenomenon easily occurs. Contents of the invention [0003] The invention overcomes the shortcomings of the prior art and provides a diffuse reflection lighting device. [0004] In order to achieve the above purpose, the technical solution adopted by the present invention is: a diffuse reflection lighting device, including: LED installed ...
