20170038045
This application claims priority to Chinese patent application no. 201510479870.6 filed on Aug. 7, 2015, the contents of which are incorporated by reference herein.
The subject matter herein generally relates to an illumination device, especially relates to a wall lamp.
LEDs have advantages of energy saving, environmental protection, long life, high color rendering index and so on. LED lamps belong to landscape lighting. So consumers want products more beautiful in the pursuit of product function at the same time. In addition, a conventional wall lamp including LEDs is directly fixed on the wall or other places, thereof an illumination angle of the wall lamp being limited.
Implementations of the present technology will now be described, by way of example only, with reference to the attached figures:
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features of the present disclosure.
Several definitions that apply throughout this disclosure will now be presented.
The term “substantially” is defined to be essentially conforming to the particular dimension, shape, or other feature that the term modifies, such that the component need not be exact. For example, “substantially rectangular” means that the object resembles a rectangle, but can have one or more deviations from a true rectangle. The term “comprising” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.

The lamp body 10 is made by one piece via die casting. The lamp body 10 includes a base 11, a first side wall 12, a second side wall 13 and a third side wall 14. The first side wall 12 and second side wall 13 respectively extend from two opposite ends of the base 11 in the same side. The third side wall 14 connects the base 11, the first side wall 12 and the second side wall 13 in the same side of the first side wall 12 and the second side wall 13. The base 11, the first side wall 12, the second side wall 13 and third side wall 14 cooperatively define a cavity 15 therebetween. The base 11 and the third side wall 14 are connected and coupled to form an L-shaped configuration. The third side wall 14 includes s an outer wall 141 and an inner wall 142. The inner wall 142 of the third side wall 14 faces the cavity 15 and the outer wall 141 is back to the cavity 15.
The base 11 is flat. The base 11 is substantially rectangular. The base 11 includes two short sides 111 and two long sides 112. The two short sides 111 can be arc-shaped. In this exemplary embodiment, the two short sides 111 are arc convex. The first side wall 12 and the second side wall 13 respectively extend from the two short sides 111 of the base 11 upwards and vertically. Preferably, the first side wall 12 and the second side wall 13 have the same shape. A width of the first side wall 12 or the second side wall 13 is gradually reduced upwards away the short sides 111 of the base 11. A bottom shape and sizes of the first side wall 12 or the second side wall 13 are the same with that of the short side 111 of the base 11. The third side wall 14 connects to a side of the first side wall 12, a side of second side wall 13 and the long side 112 of the base 11. In this exemplary embodiment, the side of the first side wall 12 and the side of the second side wall 13 connected to the third side wall 14 are arc. In other words, the outer wall 141 of the third side wall 14 is a streamlined curved surface. So the lamp body 10 has a streamlined appearance, thereof being more concise and beautiful.
A plurality of fins 16 are formed on the lamp body 10. Preferably, the fins 16 are formed on the inner wall 142 of the third side wall 14 and the base 11. In this exemplary embodiment, the fins 16 include first fins 161 and second fins 162. The first fins 161 extend from the base 11 to the cavity 15 vertically. The second fins 162 extend from the third side wall 14 to the cavity 15 vertically. Preferably, the first fins 161 are laterally formed on the base 11. The second fins 162 are vertically formed on the inner wall 142 of the third side wall 14. The two adjacent first fins 161 are spaced apart from each other. The two adjacent second fins 162 are spaced apart from each other.
Preferably, a board 17 is configured between the first fins 161 and the second fins 162. The board 17 is parallel to the base 11. The board 17 separates the first fins 161 and the second fins 162. Preferably, the first fins 161 are sandwiched between the base 11 and the board 17. The second fins 162 extend upwards from a top surface of the board 17 along the inner wall 142 of the third side wall 14.
The wall lamp 100 of the exemplary embodiment in the present disclosure further includes a fixed base 18. The fixed base 18 is formed on the lamp body 10 for fixing the connector 30. Preferably, the fixed base 18 is formed on center of the inner wall 142 of the third side wall 14.
The light emitting unit 40 is fixed on a bottom of the base 11 of the lamp body 10. The light emitting unit 40 includes at least an LED 41, a reflector 42 and a lens 43. In this exemplary embodiment, the light emitting unit 40 includes two LEDs 41. In other exemplary embodiments, the light emitting unit 40 can also includes one or a plurality of LEDs 41 to meet different power requirements. The LEDs 41, the reflector 42 and lens 43 are fixed on a bottom of the base 11 of the lamp body 10 that order. The reflector 42 covers the LEDs 41 and the lens 43 covers the reflector 42 to improve the optical properties. Preferably, the light emitting unit 40 further includes a plate 44. The plate 44 is fixed on a bottom of base 11 of the lamp body 10 and presses edges of the lens 43, thereof protecting the lens 43 from abrasion.
