Abstract

A lamp comprises a housing, a heat dissipating unit, a light emitting member and a screen. The housing includes a lens and a base on two ends thereof, with an outlet section and an inlet section being formed on the wall of the housing. The heat dissipating unit is mounted inside the housing. The light emitting member is coupled to the heat dissipating unit and electrically connects to the base of the housing. The screen is in the form of a mesh that has a plurality of tiny holes and covers the inlet section of the housing. Consequently, by use of the screen, the lamp can meet standards for safety, gas flow impedance is reduced to enhance dissipating heat dissipating effect of the heat dissipating unit and insects are prevented from entering the housing.

Claims

1. A lamp, comprising:

a housing including a lens and a base on two ends thereof, with an outlet section and an inlet section being formed on the wall of the housing;

a heat dissipating unit being mounted inside the housing;

a light emitting member being coupled to the heat dissipating unit and electrically connecting to the base of the housing; and

a screen being in the form of a mesh that has a plurality of tiny holes and covering the inlet section of the housing.

2. The lamp as defined in claim 1, wherein the inlet section consists of plural slots annularly arranged in the wall of the housing and the screen is a meshed cover attached to an inner periphery or an outer periphery of the housing.

3. The lamp as defined in claim 1, wherein the inlet section consists of plural slots annularly arranged in the wall of the housing and the screen consist of a plurality of meshed covering plates, with each meshed covering plate covering each slot of the inlet section.

4. The lamp as defined in claim 1, wherein another screen in the form of a mesh that has a plurality of tiny holes covers the outlet section of the housing.

5. The lamp as defined in claim 4, wherein the outlet section consists of plural slots annularly arranged in the wall of the housing and said another screen is a meshed cover forming the tiny holes.

6. The lamp as defined in claim 4, wherein the outlet section consists of plural slots annularly arranged in the wall of the housing and said another screen consist of a plurality of meshed covering plates, with each meshed covering plate covering each slot of the outlet section.

7. The lamp as defined in claim 1, wherein the screen is a netting member made of threads woven across each other.

8. The lamp as defined in claim 1, wherein a distance between centers of any two adjacent tiny holes of the screen is smaller than or equal to 2 mm.

9. A lamp, comprising:

a housing including a lens and a base on two ends thereof, with an outlet section and an inlet section being formed on the wall of the housing;

a heat dissipating unit being mounted inside the housing;

a light emitting member being coupled to the heat dissipating unit and electrically connecting to the base of the housing; and

a screen being in the form of a mesh that has a plurality of tiny holes and covering the outlet section of the housing.

10. The lamp as defined in claim 9, wherein the outlet section consists of plural slots annularly arranged in the wall of the housing and the screen is a meshed cover attached to an inner periphery or an outer periphery of the housing.

11. The lamp as defined in claim 9, wherein the outlet section consists of plural slots annularly arranged in the wall of the housing and the screen consist of a plurality of meshed covering plates, with each meshed covering plate covering each slot of the outlet section.

12. The lamp as defined in claim 9, wherein the screen is a netting member made of threads woven across each other.

13. The lamp as defined in claim 9, wherein a distance between centers of any two adjacent tiny holes of the screen is smaller than or equal to 2 mm.

14. The lamp as defined in claim 9, wherein another screen covers the inlet section of the housing, with said another screen and the screen covering the outlet section being jointly formed into a single piece.
