Problems solved by technology

[0008] This shows that the above-mentioned existing lighting device obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.
In order to solve the problems of lighting devices, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and general products do not have a suitable structure to solve the above problems. This is obviously a problem. Issues that relevant industry players are eager to solve

no. 1 example

[0053] see image 3 As shown, the directional lighting device 2 includes a casing 21 , an optical element 22 , and at least one light source 23 .

[0054] The housing 21 has an opening 211 . The optical element 22 covers the opening 211 to form an accommodating space 212 . The optical element 22 has a first surface 221 and a second surface 222 opposite to the first surface 221 , and the first surface 221 has at least one Fresnel pattern area 223 . image 3 The Fresnel pattern area 223 in the figure is a schematic representation, but the actual Fresnel pattern area 223 is so small that it is difficult to identify even with the naked eye.

[0055] In this embodiment, the material of the optical element 22 can be glass or plastic. If plastic is used as the material of the optical element 22, the thickness of the optical element 22 will be thinner, therefore, as Figure 4 As shown, in this embodiment, the directional lighting device 2 may further include a transparent substrat...

no. 2 example

[0061] see Figure 5 As shown, if the angles and sizes of the complex triangular protrusions 2231 on the Fresnel pattern area 223 of the optical element 22 are adjusted, a deflection angle can be generated for the parallel rays passing through the Fresnel pattern area 223, thus becoming Directional light.

no. 3 example

[0063] 6, the Fresnel pattern area 223 of the optical element 22 has at least one focal length. Angle and size, so that the light emitted by the light source 23 diverges to both sides, and the object to be irradiated can have a halo-like light beam surrounding the object to be irradiated.

[0064] In addition, in this embodiment, the optical element 22 is located between the transparent substrate 24 and the light source 23 .

Abstract

The illuminator includes a body case, an optical component, and at least a light source. The body case possesses an opening. Covering the said opening, the optical component forms an accommodation space. The optical component possesses a first surface, and a second surface opposite to the said first surface. The first surface possesses at least a zone of Fresnel pattern. The light source is setup inside the accommodation space.

Description

technical field [0001] The invention relates to a lighting device, in particular to a directional lighting device. Background technique [0002] With the increase of people's income year by year and the popularization of household electrical appliances, in modern family life, lighting devices are no longer just for the purpose of simple comprehensive lighting, but have decoration, atmosphere creation, and special local lighting, etc. and other functions. [0003] Taking daylight lamps 1 commonly used in general offices as an example, please refer to figure 1 As shown, the fluorescent lamp 1 mainly includes a base 11 , a plurality of fluorescent tubes 12 , and a reflector 13 . Wherein, a plurality of fluorescent tubes 12 are arranged in the base body 11 , and the reflector 13 is joined with the base body 11 . The reflector 13 has a plurality of reflectors 131 to reflect the light emitted by the fluorescent tube 12 to different angles, so as to increase the brightness of th...
