Technical Field

[0001] The invention relates to the technical field of energy-saving lamps, in particular to an energy-saving street lamp shade. Background Art

[0002] Street lamps are common lighting devices. Due to their wide application range and large number, their overall power consumption cannot be ignored. For this reason, people have been studying how to make street lamps more energy-efficient.

[0003] Existing street lamp shades are all reflective shades, which reflect the light from the light source onto the road surface through the reflector above. The reflected light gradually darkens from the middle to the outside. Therefore, people increase the power or increase the installation density of street lamps to meet the lighting requirements, which is not conducive to energy saving and environmental protection. Summary of the invention

[0004] In view of the problems existing in the above-mentioned prior art, the present invention provides an energy-saving street lamp shade to solve the above-mentioned technical problems.

[0005] In order to achieve the above-mentioned object of the invention, the technical solution provided by the present invention is as follows: An energy-saving street lamp shade comprises a reflector, wherein a fixing piece for fixing a light source is arranged inside the reflector, an annular transparent body is arranged inside the reflector, and the fixing piece is located above the annular transparent body and inside the annular transparent body.

[0006] Preferably, a light-transmitting cover is connected below the reflective cover, and a plurality of supporting bodies are provided on the circumferential direction of the annular transparent body, one end of the supporting body is connected to the annular transparent body, and the other end is connected to the light-transmitting cover.

[0007] Preferably, the annular transparent body is circumferentially provided with protrusions on the top surface and the bottom surface, and the thickness of the protrusions gradually decreases from the middle position to the surrounding areas.

[0008] Preferably, the outer surface of the protrusion is a spherical surface.

[0009] Preferably, the support body is a transparent support rod.

[0010] Preferably, a first connecting part is provided at the bottom of the reflective cover, and a second connecting part is provided at the top of the light-transmitting cover; the second connecting part is located on the inner side of the first connecting part and is connected to the first connecting part; a first air hole is provided on the first connecting part, and a second air hole is provided on the second connecting part at a position corresponding to the first air hole; the supporting body is connected to the first connecting part, and a blocking block is provided on the supporting body, and the blocking block blocks the second air hole on the inner side of the light-transmitting cover, and the supporting body is a bimetallic strip.

[0011] Preferably, the blocking block is a rubber block.

[0012] Preferably, the first air hole is arranged obliquely, and the top end is closer to the inner side of the light-transmitting cover than the bottom end; the second air hole is arranged obliquely, and the top end is closer to the inner side of the light-transmitting cover than the bottom end.

[0013] When the energy-saving street lamp shade provided by the present invention is used, a light source is installed on the fixing part and then fixed on the street lamp. After the street lamp is turned on, the reflector reflects the light emitted by the light source, and part of the reflected light passes through the inner and outer sides of the annular transparent body and then is emitted onto the road surface through the light-transmitting cover, and another part of the reflected light is irradiated on the transparent body and then refracted and gradually overlaps with part of the light when reaching the road surface, forming a circular ring-shaped bright area.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] For examples, see Figure 1 and Figure 2The present application provides an energy-saving street lamp shade, including a reflector 1, a fixing part 2 for fixing a light source is arranged inside the reflector, the fixing part can use an existing structure, such as a lamp socket, and the light source can use an energy-saving bulb, a lamp panel, etc., an annular transparent body 3 is arranged inside the reflector, the fixing part is located above the annular transparent body and inside the annular transparent body, wherein the orientation (such as above) in the present application is referenced to the lamp shade in the use state. The transparent body can be made of existing materials, such as glass, transparent resin, etc. Since the street lamp is installed outdoors, the present application preferably connects a translucent cover 4 below the reflector to achieve a waterproof effect. Generally, the translucent cover can be threaded or bonded to the reflector; the above-mentioned annular transparent body can be fixed on the reflector or on the translucent cover. In this embodiment, the annular transparent body is provided with a plurality of supporting bodies 5 in the circumferential direction, one end of the supporting body is connected to the annular transparent body, and the other end is connected to the translucent cover, so that the annular transparent body is fixed on the translucent cover. When fixing, the fixing part and the annular transparent body are preferably arranged concentrically.

[0017] When the above-mentioned energy-saving street lamp shade is in use, the light source is installed on the fixing part and then fixed on the street lamp. After the street lamp is turned on, the reflector reflects the light emitted by the light source, and part of the reflected light passes through the inner and outer sides of the annular transparent body and then passes through the light-transmitting cover to be emitted onto the road surface. The other part of the reflected light is irradiated on the transparent body and gradually overlaps with part of the light when it reaches the road surface after being refracted, forming a circular ring-shaped bright area. In this way, after the light reflected by the lampshade is reflected onto the road surface, the reflected light gradually darkens from the middle to the annular bright area, then brightens, and then gradually darkens. The effective irradiation area (the irradiation area that meets the lighting requirements) is greatly increased, so the power or the installation density of the street lamp can be reduced, which is beneficial to energy saving and environmental protection.

[0018] As a preferred embodiment, a plurality of protrusions 3-1 are circumferentially arranged on the top and bottom surfaces of the annular transparent body, and the thickness of the protrusions gradually decreases from the middle position to the surrounding areas. Generally, the outer surface of the protrusions can be a spherical surface, so that the protrusions on both sides cooperate with the transparent body to form a convex lens, which focuses part of the reflected light to form a plurality of annular false light sources on the road surface. The annular false light sources are diffusely reflected by the road surface, which improves the brightness and range of the annular bright area and further expands the effective illumination area.

[0019] In the above embodiment, the support body can be a transparent support rod. As a preferred embodiment, see Figure 3The reflector is provided with a first connection part 1-1 at the bottom, and the light-transmitting cover is provided with a second connection part 4-1 at the top; the second connection part is located on the inner side of the first connection part and is connected to the first connection part; the first connection part is provided with a first air hole 1-2, and the second connection part is provided with a second air hole 4-2 at a position corresponding to the first air hole; the support body is connected to the first connection part, and a blocking block 6 is provided on the support body. Generally, the blocking block can be a rubber block, and the blocking block blocks the second air hole on the inner side of the light-transmitting cover. The support body is a bimetallic strip, wherein the bimetallic strip can also use other temperature-sensitive deformable strips, as long as it can be achieved The function is that it can be deformed when the temperature reaches a certain level; when making it, the bimetallic strip can be set to an upwardly convex arc, and the blocking block is fixed on the upper surface of the bimetallic strip. In this way, when the temperature inside the lampshade is high, the bimetallic strip is deformed and bent downward, thereby driving the blocking block to rotate inward, and the second air vent is connected to the inside of the lampshade. The lampshade dissipates heat through the first air vent and the second air vent to prevent the internal temperature of the lampshade from being too high and damaging the light source. This structure is particularly suitable for LED light sources; when the temperature inside the lampshade drops, the upper metal sheet returns to its original state, and the blocking block blocks the second air vent, which has a dust-proof and waterproof effect. The above-mentioned first air vent and second air vent are preferably arranged at an angle, with the top end closer to the inside of the light-transmitting cover relative to the bottom end.
