Abstract

An illumination device for a kitchen hood includes a light case made by high heat conductive material and a circuit board is connected to an inside of the light case. A terminal is connected to the circuit board and located outside of the light case. A light unit is connected to the circuit board and located in the light case. The light unit directly contacts the inside of the light case so as to conduct the heat from the light unit to the light case. The light case includes an open bottom with which a cover is engaged and a bulb shade is located between the light unit and the cover so as to focus or guide the light beam from the light unit.

Claims

1. An illumination device for a kitchen hood, comprising:

a light case and a circuit board connected to an inside of the light case, a terminal connected to the circuit board and located outside of the light case, a light unit connected to die circuit board and located in the light case, the light case including an open bottom with which a cover is engaged, the light unit including a heat dispensing surface which directly contacts the inside of the light case which is made by high heat conductive material, so that heat from the light unit escapes via the light case, and

a flexible plate mounted to the outside of the light case and including two bent clip ends, two first holes defined through the flexible plate and connection members extending through the first holes to be connected to the circuit board.

3. The device as claimed in claim 1, wherein a bulb shade is connected with the cover and located between the cover and the light unit.

4. The device as claimed in claim 3, wherein the cover includes an opening and the bulb shade includes an illumination portion which is engaged with the opening.

5. The device as claimed in claim 4, wherein the bulb shade includes a refraction portion, a reflection portion and the illumination portion, the refraction portion is located at an upper portion of the bulb shade and made by transparent material so tat light generated from the light unit penetrates through the refraction portion, the reflection portion is inclinedly located round the refraction portion and made by reflective material, the illumination portion is located at lower portion of the bulb shade and made by transparent material.

8. The device as claimed in claim 3, wherein the light unit includes a bulb, a base, the heat dispensing surface and legs, the bulb and the heat dispensing surface are located on opposite sides of the base, the legs extend from the base radially.

10. The device as claimed in claim 8, wherein the heat dispensing surface of the light unit extends through a positioning hole defined through the circuit board and directly contacts the inside of the light case.
